A waste gas purification equipment for chemical plants integrating filtration, adsorption and dust removal

Abstract

The invention discloses a waste gas purification equipment for chemical plants integrating filtration, adsorption and dust removal, which belongs to the technical field of waste gas purification. A shielding component is arranged inside one end of the waste gas inlet pipe located inside the purification tank, and the shielding component is above the A filter assembly is installed, and an adsorption assembly is installed above the filter assembly. The invention is scientific and reasonable, safe and convenient to use, and uses the power when the exhaust gas enters the purification tank to drive the filter screen to move upwards, compressing the shaking spring, so that the shaking spring is stored Elastic potential energy, when the chemical waste gas is not continuously introduced into the purification tank, the filter screen plate will fall downward under the action of the vibration spring and gravity, and contact with the rubber column, so that the filter screen plate will be in the vibration spring and the rubber column Under the action of continuous shaking, the particulate matter filtered by the filter screen is shaken off from the filter screen, so that no additional cleaning of the filter screen is required, which is more energy-saving and environmentally friendly.

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;
