Problems solved by technology

However, for the waste plexiglass recycling industry, especially for those companies that use manual mold filling, this method will inevitably lead to incomplete waste gas treatment, and even cause secondary pollution, resulting in bad odor in the factory area. Scattered, failing to meet national environmental protection requirements
Moreover, this technology consumes more energy, which is not conducive to cost saving for enterprises.
At the same time, since there are many recyclable components in the exhaust gas, direct treatment is not conducive to recycling, resulting in unnecessary waste

Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0023] A waste gas treatment process of an acrylic factory, comprising the following steps:

[0024] Step a: The exhaust gas enters the dust collector through the exhaust pipe, and is separated by a cyclone to remove the dust in the exhaust gas;

[0025] Step b: the exhaust gas that has undergone dust removal treatment is cooled by a cooling device;

[0026] Step c: The cooled waste gas enters the spray tower from the air inlet at the bottom of the spray tower, passes through the packing layer, and is rinsed with lye to wash away the acidic and water-soluble components in the waste gas, and removes water through the demisting layer, from the spray Discharge from the top of the tower;

[0027] Step d: The exhaust gas after dehydration is pressed into the activated carbon fiber adsorption unit by the fan for adsorption treatment;

[0028] Step e: The ex...

Abstract

The invention discloses an acrylic factory waste gas treatment process and belongs to the field of waste gas treatment. The process comprises the following steps: removing dust of a waste gas; cooling; leaching with an alkali liquid, and removing fog; adsorbing with activated carbon; performing combustion treatment; filtering with slaked lime, and discharging into the atmosphere; performing thermal treatment on an adsorption saturated activated carbon fiber adsorption unit, desorbing adsorbed organic waste gases, and regenerating the adsorption unit; separating and recycling desorbed waste gases. By adopting the process, the waste gas purification degree is increased, meanwhile useful waste gases are recycled, and the purposes of energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a waste gas treatment process of an acrylic factory. Background technique [0002] The organic waste gas produced by the waste plexiglass recycling industry has complex components and low concentration. The process waste gas generated during production has not been treated at the end, and the organic waste gas is discharged into the air indiscriminately. Over the years, the surrounding air quality has accelerated and deteriorated. The main pollutants in the waste organic glass recycling industry are condensation tail gas, vacuum pump exhaust gas, cracking and rectification residue. Its main components are organic substances such as methyl methacrylate, methyl acrylate, methacrylic acid, and methanol. [0003] At present, condensation method, adsorption method, catalytic combustion method, adsorption + catalytic combustion method, photocatalytic method, membrane technology meth...
