(1) Dry filter
In order to prevent the paint mist particles in the exhaust gas from blocking the adsorption filler (activated carbon) and affecting its adsorption performance of organic matter, it is necessary to ensure that the gas source of the adsorption treatment system is clean and dust-free. Before entering the activated carbon adsorption and concentration unit, it is necessary to carry out deep dust removal pretreatment to ensure that the dust removal efficiency reaches more than 99%. The dry dust remover adopts two-stage purification, one is medium efficiency and the other is high efficiency. Two stage dry filtration process, one medium efficiency z85, two medium efficiency g95.
(2) Activated carbon adsorption box
The activated carbon adsorption box is the key equipment to achieve the emission standard of the spray paint exhaust gas. It is very important to select the activated carbon with excellent performance and design the reasonable size of the activated carbon adsorption device. In this equipment, a new type of modular honeycomb activated carbon adsorption material is adopted, which has the ability of water resistance. Compared with granular activated carbon, it has the advantages of thermodynamic performance, low resistance, low consumption, high adsorption rate, etc., which is very suitable for use in large air volume. It has excellent adsorption performance. Its structure is porous honeycomb, with developed pore structure, large specific surface area and small fluid resistance The product is especially suitable for the purification and treatment of organic waste gas with large air volume and low concentration, such as the treatment of toxic and harmful waste gas such as xylene and butyl acetate.
(3) Catalytic burner
The regeneration method of catalytic combustion activated carbon is: the organic gas source in the desorption equipment is sent to the catalytic combustion regeneration device through the action of induced draft fan. Firstly, it passes through the dust arrester system, then enters the heat exchanger, and then it is sent to the heating chamber. Through the heating device, the gas reaches the combustion reaction temperature, and then through the catalytic bed, the organic gas is decomposed into carbon dioxide and water The temperature of the desorbed gas increases to the reaction temperature. After catalytic combustion, the removal rate of desorption gas is over 97%.
The core equipment of catalytic combustion is composed of heat exchanger, catalytic bed, electric heating element, fire and dust arrester and explosion-proof device. The fire-retardant dust remover is located on the air inlet pipe, and the explosion-proof device is set on the top of the main engine.
(4) Flame arrestor
Flame arrester is a device to prevent the spread of flame (deflagration or detonation) passing through. It is composed of flame retardant core, flame arrester shell and accessories. It is a safety device to prevent the spread of flammable gas flame.
One of the necessary conditions for combustion is to reach a certain temperature, that is, the ignition point. Below the ignition point, combustion will stop. According to this principle, as long as the temperature of the burning material is lowered below its ignition point, the spread of the flame can be prevented. When the flame passes through many small channels of the fire arresting element, it will become a number of small flames. When designing the internal flame arrestor, the contact area between the small flame and the channel wall should be expanded as much as possible, and the heat transfer should be strengthened to make the flame temperature lower than the ignition point, so as to prevent the flame from spreading.
