Spray tower price, spray tower manufacturer
The packing layer inside the spray tower serves as a mass transfer device for the gas-liquid two-phase contact component. The bottom of the packed tower is equipped with a packing support plate, and the packing is placed on the support plate in a disorderly manner. Install a packing pressure plate above the packing to prevent it from being blown by upward airflow. The spray liquid of the spray tower is sprayed onto the packing through the liquid distributor from the top of the tower and flows down along the surface of the packing. Gas is sent from the bottom of the tower, distributed by the gas distribution device, and continuously flows against the liquid through the gaps in the packing layer. On the surface of the packing, the gas-liquid two phases are in close contact for mass transfer. When liquid flows downwards along the packing layer, wall flow phenomenon may sometimes occur, and the wall flow effect causes uneven distribution of gas-liquid phases in the packing layer, resulting in a decrease in mass transfer efficiency. Therefore, the filling layer inside the spray tower is divided into two sections, with a redistribution device installed in the middle. After redistribution, it is sprayed onto the lower filling layer.Spray tower manufacturer1. Adjustment of circulating water volume: It is determined by the spray tower water supply pump. When one boiler is running, one can be turned on. When two or three pumps are running simultaneously in winter, both pumps should be turned on. The flow rate of the mud pump should be adjusted according to the flow rate of the circulating pump to make it equal.2. Dosage in the dosing tank of the spray tower: When running a boiler, add 2 bags of alkali and 5 bags of hydrated lime. If two or three boilers are running in winter, the dosage can be increased by a corresponding multiple.The sedimentation tank of the spray tower should be cleaned regularly, once a week in summer and once every three days in winter.4. When discharging the ash water separator, it should be discharged once per shift. The discharge valves should be opened separately until clear water is discharged.5. The above rotating components should be regularly inspected and lubricated, and any faults should be promptly eliminated to ensure the desulfurization effect of the spray tower.6. When adding medication up and down stairs, attention should be paid to safety, and there should be independent security and mutual security awareness.7. After work is completed, it is necessary to clean up and tidy up in a timely manner, and ensure that the site is clean when people leave. Date：2024-01-12 -

The performance of fiberglass desulfurization tower is quite stable
Fiberglass desulfurization tower:1. Suitable for operating equipment without noise. The performance of the desulfurization tower is quite stable, and there should be no noise generated during operation. If there is noise, it should be stopped immediately to check if the equipment is installed correctly,2. Check if the tower installation is stable. This may seem like an inconspicuous small matter, but it is important for the normal use of fiberglass desulfurization towers. Purification towers are equipment that needs to be used for a long time, so installation must be firm,3. Check if the fan is running properly. The fan inside the tower plays a crucial role in the normal operation of the desulfurization tower, and the performance of the fan determines the efficiency of equipment desulfurization. Daily attention must be paid to the maintenance of the fan.4. The tower body should avoid approaching flammable and explosive materials. Fiberglass belongs to flammable materials, so it is important to pay attention to fire prevention in daily life.The flue gas desulfurization system is used for the function of thermal power plants, mainly to remove sulfides from the flue gas. There are two methods for desulfurization: one is to add an absorbent to coal, so that SO2 reacts during the combustion process to generate solid waste, which remains in fly ash. This desulfurization technology, also known as dry desulfurization, has an efficiency of no more than 80% and is now rarely used; Another method is to install an absorption tower after the dust collector, using alkaline liquid to wash and absorb SO2 in the flue gas, in order to achieve the goal of purifying the flue gas. This technology, also known as wet flue gas desulfurization, has a theoretical desulfurization rate of up to 99%.Desulfurization tower refers to the core device of wet desulfurization. In the field of desulfurization, a desulfurization tower, also known as an absorption tower, as the name suggests, is a device that absorbs pollutants. Broadly speaking, a tower that undergoes reactions such as SO2 absorption within it.The so-called industrial absorption tower, in simple terms, the fiberglass absorption tower used in industry is an industrial absorption tower, but not all absorption towers can be used in industry, especially absorption towers that do not meet industrial usage requirements cannot be used in industry. So only absorption towers that meet what requirements can be used in industry?As an industrial fiberglass absorption tower, it can be used in industry. Firstly, the contact surface and time between gas and liquid inside the tower should be sufficient. Secondly, the disturbance in gas-liquid two-phase should be strong. Secondly, the industrial absorption tower should meet the requirements of simple operation, high operational stability, low resistance, low energy consumption, and easy maintenance. In addition, absorption towers used in industry also need to have certain mechanical strength and corrosion resistance.1. Thermal power plants generally use cooling towers. After heating, water generates high-pressure gas to drive the turbine to generate electricity, while the remaining gas needs to be cooled. The working principle is as follows: the water on the cooling tower of the power plant is pumped up and evenly dispersed and dropped down through a water distributor. Generally, the height of the cooling tower is several tens of meters, like a huge chimney, which can draw air up from below and take away heat during the contact between air and water droplets, thus serving as cooling water2. Central air conditioning also has a cooling tower function to cool the circulating liquid.3. There are also professional FRP cooling towers, commonly known as cooling water towers, cold water towers, cooling water towers, FRP towers, water towers, etc., which are mainly square, round, cross flow, counter flow, and packless spray type series cooling towers.

Overview of Odor Waste Gas Treatment
Overview of Odor Waste Gas Treatment:Stinky gas pollution is a gas substance that affects the olfactory organs, causing unhappiness and endangering the living environment. It is a relatively common environmental hazard that has been internationally recognized. It is studied and controlled as a single listed hazard.In recent years, China has also begun to pay attention to the monitoring and prevention of odorous waste gas treatment, and has formulated emission standards and analysis methods for some odorous compounds. The primary goal of the odor pollution prevention and control policy is to meet the emission standards for odor substances specified in GB 14554-93, with the ultimate intention of eliminating odor and creating a odorless working and living environment.The amount of odor perceived by people is directly proportional to the impact of odorous substances on their sense of smell. It is clear that even if 90% of the odorous exhaust gas is removed, the concentration of odor perceived by people's sense of smell only decreases by half. This determines that the prevention and control of odorous waste gas treatment is more difficult than the prevention and control of other atmospheric pollutants. To eliminate odors, it is dozens to thousands of times more stringent than meeting emission standards. Therefore, strengthening the treatment of odorous waste gas pollution is very important.

The principle of photocatalytic oxidation for deodorization
The photocatalytic oxidation method uses catalysts to accelerate the rate of liquid-phase oxidation and decomposition of odors.The photocatalytic oxidation method using neodymium dioxide as a catalyst has a good removal effect on odor. In the past 20 years of research, it has been found that photocatalytic technology directly uses 02 in the air as an oxidant, under mild reaction conditions (room temperature, normal pressure), and has the ability to purify almost all pollutants. Common photocatalysts are mostly metal oxides or sulfides, such as TiC) 2, ZnO, ZnS, CdS, and PbS.However, due to photo corrosion and chemical corrosion, TiC) 2 * ZnO has better practicality, with Ding 102 being the most widely used. TiO2 has the best comprehensive performance, with high photocatalytic activity (higher than ZnO), stable chemical properties, strong redox properties, insoluble, non-toxic, and low cost. It is the most widely studied and applied single compound photocatalyst. The essence of semiconductor photocatalysis is the redox reaction in photoelectric conversion. According to the electronic structure of semiconductors, when they absorb a photon with energy not less than their bandgap energy (? G), the electron (e2) will transition from the full valence band to the empty conduction band, leaving a positively charged hole (h+) in the valence band. Valence band holes have strong oxidizing properties, while conduction band electrons have strong reducing properties. They can directly interact with reactants and also react with other electron donors and acceptors adsorbed on the catalyst. For example, holes can oxidize H20, and electrons can reduce 02 in the air, generating H2() 2 The OH group and Hoy group have strong oxidation ability and can effectively oxidize odor pollutants, ultimately decomposing them into inorganic small molecules such as CO2 and H2O, achieving the goal of eliminating odor.

Knowledge of Installation and Maintenance of Waste Gas Treatment Tower
The exhaust gas treatment tower is a device that completes the absorption operation. It can be divided into three categories based on the shape of gas-liquid phase touch. The first type is plate tower, bubbling absorption tower, and mixing bubbling absorption tower where gas is dispersed in the liquid phase in the shape of bubbles; The second type is the ejector, Venturi tube and spray tower with liquid dispersed in the gas phase in the form of droplets; The third type is packed absorption towers and falling film absorption towers where the liquid moves in a film like manner and touches the gas phase. The activity method of gas-liquid two-phase flow inside the tower can be either counter flow or parallel flow. Generally, countercurrent operation is used, and the absorbent participates in top-down activity at the top of the tower, touching the gas moving from bottom to top. The liquid that absorbs the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.In the era of increasingly developed industry, exhaust gas treatment towers play a crucial role. They can treat industrial exhaust gases and have a crucial effect on air purification. If there were no exhaust gas treatment towers, it's hard to imagine what a mess industry would become. So, how much do you know about the installation and maintenance of waste gas treatment towers?Users carry out concrete foundation construction based on foundation data; The equipment should be installed on a concrete foundation that is more than 100mm above the ground; Supporting pipelines, valves, etc. should have independent support and cannot be fixed on tower equipment; During installation, attention should be paid to maintaining the equipment and avoiding damage to the body and exposed components. When connecting the tower flange with the external flange, the correct tightening method should be selected, and excessive force should not be applied to avoid cracking of the flange. Steel gaskets shall not be used for flange gaskets, and corrosion-resistant and oil resistant rubber gaskets can be used; After the equipment installation is completed, water is used for cyclic debugging, and it operates normally without any signs of running, emitting, dripping, leaking, or clogging.In addition, to ensure the normal operation of the tower equipment, a dedicated person must be responsible for handling it.
