How to use photocatalytic oxidation to treat organic waste gas generated in chemical plants
The solvent consumption in the production process of the chemical industry is large, mainly low boiling volatile organic compounds (VOCs), of which a considerable portion will be discharged in the form of exhaust gas, generating a large amount of solvent exhaust gas. Organic waste gas is a part of gaseous pollutants, which come from various industries such as chemical waste gas, fluorinated waste gas, gaseous hydrocarbons, and foul smelling gases. Organic waste gas generally has the characteristics of being flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat.How to use photocatalytic treatment equipment to treat organic waste gas generated by chemical plants?Mainly using photocatalytic oxidation equipment to treat organic waste gas generated by chemical plants:Photocatalytic oxidation is a catalytic reaction that occurs under the action of visible light from the outside. The photocatalytic oxidation reaction uses photocatalysts and air as catalysts, and ultraviolet light as energy to degrade organic matter into CO2, H2O, and other non-toxic and harmless components. Using artificial ultraviolet vacuum waves as the driving force, nano TiO2 catalysts with strong activity and high reaction efficiency are treated with unique technology to stimulate catalytic reactions. After treatment, the waste odorous gas can achieve more ideal purification effects, with almost no maintenance costs and no secondary pollution.The projects that photocatalytic oxidation equipment has been applied to include: waste gas purification engineering in the food ingredient and food additive industry, odor treatment and purification engineering in domestic and industrial wastewater, odor treatment engineering in the chemical and pharmaceutical industry, odor purification engineering in urban sludge treatment, automobile casting exhaust gas purification engineering, waste oil regeneration industry exhaust gas purification engineering, petrochemical raw material loading and unloading cleaning exhaust gas purification engineering Smoke production industry odor purification project, precision electronics industry odor purification project, fish meal feed industry odor purification project, public place air purification project, plastic and rubber industry odor purification project, etc. Date：2024-01-12 -
Changzhou photocatalytic equipment manufacturer
It is reported that during the 12th Five Year Plan period, China's pump and vacuum equipment manufacturing industry will maintain a market growth rate of about 20%, and the sales range will be around 158.7 billion yuan by 2015. When GDP grows at a rate of 4% per year in the next 10 years, the pump industry market will increase at a rate of 5% per year. In 2011, the total global pump market was around 37 billion US dollars. As a sub industry of the pump industry, agricultural water pumps, with their sales expenses accounting for 14% of the pump industry's sales expenses, will surpass $6 billion in the global agricultural water pump market by 2015.With the continuous promotion of the process of household ownership, China's sewage treatment industry once formed a relatively complete industrial chain. Including upstream sewage treatment equipment, treatment agents, water supply and drainage pipelines, midstream sewage treatment engineering support, and downstream sewage treatment operation services. In this industry chain, the sewage treatment rate used to exceed 70%, and the investment format fundamentally constituted it.In the investment of sewage treatment equipment, water pumps account for about 15% of the total investment in mechanical equipment. Based on this proportion, the demand for pump products in urban sewage treatment during the 12th Five Year Plan period will be around 60 billion yuan, and there will be nearly 40 billion yuan in market demand in the next three years, which is beneficial for the centrifugal pump industry.In the next 3-5 years, there will be a significant increase in the demand for high-efficiency water pumps, viscous oil pumps, oil pipeline pumps, and screw pumps in the oil industry, with a demand for 140000 to 150000 units of various industrial pumps. Regarding the three major chemical pumps, the market for large-scale methylamine pumps for fertilizers, large and medium-sized low-temperature high-pressure magnetic pumps, and non-metallic chemical pumps made of special materials will also expand, with a demand for various types of chemical pumps ranging from 100000 to 120000 units.In the next 20 years, China's power industry will grow at a high speed. Key demand includes 3500 to 4200 important pump types, including feedwater pumps, booster pumps, cycle pumps, condensate pumps, condenser water ring vacuum pumps, centrifugal ash removal pumps, incoming and outgoing ash pumps, coincidence pumps, and metering pumps. We require 1400-1800 pumps for nuclear power units, including nuclear main pumps, upwash pumps, shutdown cooling pumps, spray pumps, boiler feedwater pumps, metering pumps, etc.According to relevant sources, the demand for pump products in the Chinese power industry accounts for approximately 16.4% of the total market. Due to the shrinking investment in the thermal power industry, the growth rate of demand for pump products in the power industry will slow down. It is estimated that during the 12th Five Year Plan period, this growth rate will persist between 10% and 15%, with demand accounting for about 15% of the entire pump industry market.

Technical principles of low-temperature plasma exhaust gas treatment equipment
Nowadays, there are many applications of waste gas treatment technology, and low-temperature plasma has become a very common waste gas treatment process. Below, our company will introduce the technical principle of low-temperature plasma waste gas treatment equipment to youTechnical IntroductionLow temperature plasma degradation of pollutants utilizes high-energy active particles such as electrons, ions, atoms, and free radicals to interact with pollutants in the exhaust gas, causing pollutant molecules to decompose in a very short time and undergo various subsequent reactions to achieve the goal of decomposing pollutants.The complete set of low-temperature plasma exhaust gas treatment equipment and technology, as a new type of gaseous pollutant treatment technology, is an interdisciplinary and comprehensive electronic chemistry technology that integrates physics, chemistry, biology, and environmental science. Due to its ability to efficiently decompose pollutant molecules and low treatment energy consumption, it is currently one of the most promising and effective technical methods in air pollution treatment both domestically and internationally, Its broad prospects for use and promotion have opened up a new approach for the treatment of VOC organic waste gases and odorous gases in the industrial field.Advantages of low-temperature plasma exhaust gas treatment equipment1、 No need to add any substances: Low temperature plasma exhaust gas treatment is a dry purification process, a brand new purification process that does not require any additives, does not produce wastewater or waste residue, and does not cause secondary pollution.2、 Strong adaptability: long-lasting purification function, no need for dedicated personnel to monitor. It can adapt to the purification treatment of high concentration, atmospheric volume, and different gaseous substances. It can operate in the purification area at high temperatures of 250 ℃ and low temperatures of -50 ℃, especially in humid or even saturated environments. It can work continuously 24 hours a day, ensuring stable and reliable long-term operation.3、 Low consumption and energy saving: Low operating cost and power saving are one of the core patented technologies of "low-temperature plasma". It can handle 1000M3/h odor and consume only 0.25 kWh of electricity. This equipment has no mechanical action, high degree of automation, simple process, simple operation, and is convenient without the need for dedicated management and daily maintenance.
