A chemical plant in acidic organic emission control technology program 
 I. Project Overview 

 Shanghai Chemical Co., Ltd. the existing water series of the production process, raw material point in the reactor dosing a small amount of volatile gases. Raw material dosing points are distributed in two production plants, now workshop marked as emissions workshop # 1 and 2 emissions workshop. The emission of the two workshops and the existing collection configuration is as follows: 
 1 emissions workshops: 
 1 # a raw material of the emission workshop added emission point. Raw materials, investment and increase the emission point configuration set the hood sets, and configure the exhaust pipe and exhaust fan, direct emissions from the roof of the workshop; 
 2 emissions workshops: 
 2 # 4 emissions workshop raw materials added to the emission point. Four discharge points have been ranked to set the hood and connect the exhaust pipe and exhaust fan, direct emissions from the roof of the workshop. 
 Second, the major pollutants 

 ? Exhaust main ingredient: formaldehyde, phenol, sulfuric acid mist, total non-methane hydrocarbons, ammonia. 
 ? Exhaust gas temperature: 25 ℃ -30 ℃ 
 ? Exhaust air volume: 1 # emission sources to configure the wind about 2000-3000m3 / h; 2 # emission source configuration wind about 5000-7000m3 / h. 
 Third, the governance principles 

 A purification system design to achieve the national emission standards of air pollutants emission standards for new sources of pollution emissions extremal two of GB16297-1996. 
 2, two of the atmospheric environment quality standards for ambient air quality standard (GB3095-1996); 
 Purification equipment requirements, simple operation, smooth running, safe and reliable, in line with the motor class design standards. 
 4, the most economical purification system investment, low running costs of the principle. 
 Fourth, the purification treatment process 
 A design based on: 

 Emissions workshop # 1 and # 2 exhaust emissions workshop emission point distribution, such as the use of separate governance, one-time higher input costs, and post-operational and management costs are high, so the case design uses a separate collection, centralized purification governance strategy. The company design # 1 emissions workshop exhaust source and 2 workshop exhaust emissions by sources of emissions emissions, use of existing waste gas collection system to collect, and then brought together through the air supply pipe to a centralized purification. 

 To deal with the nominal concentration of design: 
 Comprehensive adsorption purification of the nominal concentration of 200 mg / m3; 
 3, handle the rated air flow design 
 Comprehensive adsorption purification rated air flow 10000m3 / h 
 4, the purification process flow diagram: 
 5, control flow statements: 
 Emission points for a # emission workshop, use of the existing set of hood and gas gathering fans, collected exhaust gas transport by pipeline to 2 emissions workshop 2 workshop exhaust air through a pipe convergence. 
 2 # emission point exhaust emissions workshop to collect, collection, use of the existing set of hood and gas gathering fans exhausted to the outside. Connected through the exhaust pipe of the pipe with a # emission workshop merger. Pipeline access activated carbon in the combined exhaust gas purification tower. Exhaust in the rear booster fan power, purification by activated carbon tower. Purification of the standard gas by 15 meters above the exhaust, high-altitude emissions. 
 6, activated carbon exhaust gas purification tower on 
 Organic waste gas into the of HXT-Q organic waste gas adsorption before the processor, particulate matter, the purification of the oil spill, prevent contamination adsorption carrier. Into the the HXT type activated carbon organic waste gas adsorption purification device for purifying exhaust gas after after preliminary purification. This purification equipment physical purification method of organic waste gas adsorption in the adsorption carrier to purify the purpose. The purification installations adsorption carrier to adopt the columnar granular activated carbon material, large adsorption surface area, the removal efficiency more than 90%. This purification devices, small size, clean, high efficiency, good activity. Adsorption purification device carrier drawer modules, quick chuck closed, usually in the 5 minutes loading and unloading is completed. Adsorption cycle depending on the use of generally three months, the adsorption weeks after the expiration to replace the activated carbon, to ensure that exhaust emissions standards. 
 Fifth, the emission standards 

 "Air pollutant emission standards GB16297-1996 new pollution sources extremal two execution. 
 Maximum Contaminant allows 
 Emission concentration maximum allowable emission rate 
 Exhaust two 
 Formaldehyde 25mg/m3 15m 0.26kg / h 
 Phenolic 100mg/m3 0.1kg / h 
 Sulfuric acid mist 45mg/m3 1.5kg / h 
 Non-methane hydrocarbons 120 mg/m3, 10 kg / h 


 Conclusion: (1) organic waste gas after comprehensive treatment can reach all kinds of national emission standards 
 (2) the standard concentration for the final emission concentration. 
 2, the emitted pollutant discharge standards (GB14554-93) 
 Maximum Contaminant allows 
 Emission concentration maximum allowable emission rate 
 Exhaust two 
 Ammonia 15m 4.9kg / h 



 Sixth, after-sales service 

 We are responsible for the construction of the project, the warranty period of one year, provide after-sales service long after the warranty expires. Supply-side delivery of the equipment prior to use, professional and technical personnel responsible for camp to the demand side, the free operating on the demand side, operators and maintenance personnel, maintenance, training, help need to be familiar with equipment operation, master maintenance essentials. Supply-side has a full-time service department and equipped with professional staff, the need to provide fast, courteous, professional service. The demand side in the equipment operation, such as quality problems, the supply side in the 48 hours after receiving the demand-side repair (only on working days), arrive at the scene.
