Equipment for treating VOCs (volatile organic chemicals) exhaust gases and use method of equipment

Abstract

The invention relates to equipment for treating VOCs (volatile organic chemicals) exhaust gases. The equipment comprises an inner barrel and an outer barrel which are vertically and fixedly arranged, an interlining cavity between the inner barrel and the outer barrel is communicated with a low-concentration exhaust pipe, the inner cavity of the inner barrel is connected with a high-concentration exhaust pipe, a primary combustion chamber communicated with the high-concentration exhaust pipe and a secondary combustion chamber located above the primary combustion chamber and communicated with the primary combustion chamber are further fixed in the inner barrel, a primary combustor and a secondary combustor are arranged in each of the primary combustion chamber and the secondary combustion chamber, a preheating cavity is arranged on the outside of the primary combustion chamber in a surrounding manner, the preheating cavity is communicated with the interlining cavity through a pipe provided with a pressure pump, the water outlet of the pipe is connected with atomizers arranged downwards, and the atomizers are located at the position above the joint of the low-concentration exhaust pipe and the outer barrel. The multi-stage multi-point atomization technology is utilized, liquid absorbing the exhaust gases is fully atomized, contact area and contact time of the exhaust gases and the absorbing liquid are increased, and absorption efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to equipment and a method for treating VOCs waste gas. Background technique [0002] With the improvement of people's awareness of environmental protection and the country's environmental protection requirements, the gas emitted by industry must be treated before it can be discharged. For VOCs waste gas, the traditional treatment equipment uses the waste gas directly into the liquid that can absorb the waste gas. In this treatment method, the contact area between the gas and the liquid is small, the contact time is short, and the absorption effect is poor, resulting in secondary pollution (sewage ), which cannot meet the high requirements of environmental protection, and the existing treatment equipment can only treat high-concentration waste gas or low-concentration waste gas alone. Contents of the invention [0003] Aiming at the deficiencies of the p...
