Waste gas purification equipment integrating filtration, adsorption and dust removal for chemical plant

Abstract

The invention discloses waste gas purification equipment integrating filtration, adsorption and dust removal for a chemical plant, and belongs to the technical field of waste gas purification. A shielding assembly is arranged in the end, located in a purification tank, of a waste gas inlet pipe; a filtering assembly is mounted above the shielding assembly; and an adsorption assembly is mounted above the filtering assembly. The equipment is scientific and reasonable, and is safe and convenient to use; a filter screen plate is driven to move upwards by power generated when waste gas enters the purification tank in order to compress a shaking spring and make the shaking spring store elastic potential energy, and when the chemical waste gas is not continuously introduced into the purificationtank, the filter screen plate falls down under the action of the shaking spring and gravity, the filter screen plate is in contact with a rubber column, so that the filter screen plate continuously shakes under the action of the shaking spring and the rubber column, particulate matters filtered by the filter screen plate are shaken off from the filter screen plate, the filter screen plate does notneed to be additionally cleaned, more energy is saved, and more environment is protected.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to an exhaust gas purification equipment for chemical plants integrating filtration, adsorption and dust removal. Background technique [0002] Chemical waste gas refers to the poisonous and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity, which seriously pollutes the environment and affects human health. In the prior art, the chemical modification of activated carbon, targeted adsorption, and reduction of external emissions are widely used low-cost waste gas treatment methods. However, the particulate matter in chemical waste gas will seriously hinder the absorption of harmful gases by activated carbon, so , filtering particulate matter before adsorbing harmful gases from chemical waste gas can effectively prolong the ser...

AI Technical Summary

Problems solved by technology

[0003] 1. When filtering the particulate matter in the chemical waste gas, dust and other particulate matter will accumulate on the filter screen, which will affect the filtering effect of the chemical waste gas. In addition, using vibration equipment to vibrate the filter screen board requires additional energy and cannot To achieve energy conservation and environmental protection;

[0004] 2. The existing purification equipment takes extra time to replace the activated carbon screen, which affects the normal purification of chemical waste gas by the purification equipment. If the activated carbon screen is not replaced after it is saturated, it will also affect the purification effect of the activated carbon screen;
