VOCs tail gas treatment apparatus

Abstract

The invention discloses a VOCs tail gas treatment apparatus. The apparatus comprises an exhaust gas prefilter, an adsorption tank, a desorption tank and a blower, the exhaust gas prefilter is connected with the adsorption tank, the bottom of the adsorption tank is connected with a tail gas pipeline, the tail gas pipeline is divided into two paths, one path is connected with an induced draught fan, the other path is connected with a catalysis burning device through a VOCs pipeline, the bottom of the desorption tank is connected with the VOCs pipeline, the VOCs pipeline is divided into two channels, one channel is connected with the induced draught fan, the other channel is connected with the catalysis burning device, and the top of the desorption tank is connected with the burning gas flow outlet of the catalysis burning device; and the adsorption tank is connected with the desorption tank through an ACF particle circulation pipeline, the gas inlet of an external circulating pipeline is connected with a blower through a filter screen, the external circulating pipeline is connected to a stepped interlayer in the adsorption tank and a stepped interlayer in the desorption tank respectively, and ACF particles entering from an ACF particle feeding port flow through the ACF particle circulating pipeline, and are discharged from an ACF particle discharging port. VOCs (volatile organic compounds) can be effectively removed through the apparatus.

Description

technical field [0001] The invention relates to an air protection device, in particular to the technical field of processing volatile organic compounds (VOCs) emitted during the production or use of plastic products in the plastic industry. Background technique [0002] Plastic has become an important part of our daily life, its consumption is constantly increasing, and with the continuous improvement and development of technology, the waste plastic recycling industry has also developed rapidly, but whether it is the production of plastic products Or reproduction and utilization, the process has produced more and more serious pollution to human health and the living environment, especially the emission of volatile organic compounds (VOCs for short). VOCs have caused non-negligible harm to human health and the atmospheric environment. In order to control the emission of VOCs in the plastics industry, the technical transformation of existing enterprises in the plastics indust...

Problems solved by technology

In order to control the emission of VOCs in the plastics industry, the technical transformation of existing enterprises in the plastics industry, especially the absorption treatment technology, timely rectification and replacement of saturated adsorbent activated carbon and other standard requirements are constantly improving, but the existing VOCs treatment technology There are problems such as low efficiency, low removal rate, large resource consumption and secondary pollution, which are difficult to meet these increasingly stringent standards.
