Organic waste gas treatment of Changchun Yi Yi Pharmaceutical Co., Ltd.
1, Changchun Baiyi Pharmaceutical Co., Ltd is Changchun BCHT Biotechnology Co. subsidiary company, incorporated in July 30, 2010, the registered capital of 60 million yuan. The company is located in Changchun hi tech Industrial Development Zone, covers an area of 40 thousand square meters, the existing building area of 14 thousand square meters.
While vigorously improving the economic efficiency of enterprises, paying attention to the quality of products, carrying out the concept of "from environmental protection to sustainable development economy", we intend to control the waste gas produced in the process of production. Commissioned by the company, Xuzhou Longtai environmental protection equipment manufacturing Co., Ltd. prepared a preliminary design program for its odor gas treatment.
We are guided by the principle of mature and reliable process, reasonable overall layout, convenient operation and management and low processing cost.
Project overview
This project is the chemical waste gas purification project, the basic situation of waste gas treatment:
1. The emission of waste gas treatment is 7647m3/h.
2. The composition of organic pollution gas is DMF, piperidine, methylene chloride, three acetic acid, ethyl two mercaptan, ether, acetonitrile and so on.
Dragon environmental protection to purify the exhaust gas of the project, including waste gas treatment plan, design, construction and installation debugging.
design basis
1) first-hand information obtained from field surveys
2) the environmental protection law of the People's Republic of China (1989-12-26)
3) the law of the People's Republic of China on the prevention and control of air pollution (2000-04-29)
4) ambient air quality standard (GB3095-1996)
5) decision of the State Council on Several Issues concerning environmental protection issued by the State Council (1996) No. 31
6) Order No. seventy-second of the president of the People's Republic of China on the clean production promotion act of the People's Republic of China
7) national environmental protection "fifteen plan"
8) comprehensive emission standard for air pollutants (GB16297-1996)
9) emission standard for odor pollutants (GB14554-1993)
10) code for design of power supply and distribution systems (GB50052-1995)
11) the experience gained in the project of the project for the management of similar environmental pollution projects by Longtai environmental protection equipment
Solution
Purification process / process characteristics, safety, purification efficiency, total investment
(one-time investment + operating costs) energy consumption, there are two pollution?
UV lights are unsafe and generally high
Water (chemical) spray + activity
Carbon adsorption (caustic soda),
Hydrogen peroxide, etc.) safe in general
(likely to fail) low high solid waste treatment
Combustion method is unsafe, high, very high
Low temperature plasma is unsafe
(organic waste gases flammable and explosive) high, high, none
LTAOP high safety (95% +) moderate
(operating cost is 1/10 of activated carbon) low none
Biological filter safety is generally high
LTAOP technology principle
The ozone generator generates a positive charge with positive charge of ozone molecules O3+, positive charge, ozone formation of a large number of hydroxyl groups on special oxidation accelerator LTC-A/B developed by our company under the action of (OH), hydroxyl (OH) has a strong oxidation ability. In advanced oxidation decomposition, O3+, involved in the direct reaction of OH in indirect reaction in PH. 4 under the condition of 90% completed by indirect reaction. Especially for the decomposition of odorous gases, the decomposition rate is over 95% after direct and indirect reactions.
Technological process
Waste gas treatment process
Long Tai environmental protection company is currently well documented in the domestic organic waste gas treatment project, the best environmental protection manufacturers.
According to the complexity and diversity of the chemical waste gas treatment project, the long environmental protection company has constantly sum up experience in the practice, constantly technological innovation, and adopt unique design for different projects.
After the comprehensive analysis of the construction cost, operating cost, maintenance cost and purification effect, we suggest that the exhaust gas should be treated with advanced oxidation system.
The exhaust gas through the pipeline into the collection after the dragon net advanced oxidation system, active free radical oxidation system can produce a large number of hydroxyl radicals and ion agent active groups DMF, piperidine, dichloromethane, three fluorine acetic acid, ethylene two mercaptan, ether, acetonitrile and other harmful pollutants and the chemical reaction, a large number of harmful pollutants are decomposed for carbon dioxide, water, harmless acid after catalytic oxidation system, to further processing, hydroxyl radical and ion agent reactive groups in catalytic oxidation agent and residual harmful pollutants react again harmful pollutants to be completely decomposed into carbon dioxide, water and acid alkali absorption system into harmless, thephysico chemical spray washing the chemical spray washing system, the absorption liquid by countercurrent type (neutralization liquid NaOH) atomization spray washing, thus To achieve the clean effect, the scheme not only has high efficiency, but also can efficiently remove DMF, piperidine, methylene chloride, three acetic acid, ethyl two mercaptan, ethyl ether, acetonitrile and other pollutants.
The use of LTAOP waste gas treatment system, the effect can not only meet the national level two emission standards, but also far below the standard, and the operation and maintenance costs are low.

After-sale service
In order to enable the owner to operate the relevant equipment properly and ensure the normal operation of the system, technical training is needed for the relevant personnel. It includes basic knowledge, facilities, operation methods and emergency handling methods. We provide free personnel training two times. The first training site is on the spot, with the basic knowledge of waste gas treatment. The second training site is also on the spot. The contents are the operation methods of the waste gas treatment station and the emergency treatment methods. The whole training plan is completed during the commissioning of the waste gas treatment facility.
The formal transfer of owner management in equipment, regular customer service service actively, strengthen ties with the owners, the owners in the operation process of solving difficulties, achieve "active service, regular visits, the call will be needed to", specifically:
