Adsorbent capable of removing toxic substances in exhaust gas

Abstract

The invention discloses an adsorbent capable of removing toxic substances in exhaust gas. The adsorbent is characterized by being prepared from the following raw materials, by weight part: 8-15 of calcium carbonate fiber, 20-40 of tetrabutyl titanate, 3-5 of silica sol, 6-8 of calcium aluminate, 60-80 of volcanic rock, 6-9 of PA6 nylon powder, 3-4 of gelatin, 1-3 of ammonium bicarbonate, 4-6 of montmorillonite, 6-8 of calcium chloride, and a proper amount of deionized water. Montmorillonite and calcium chloride added in the adsorbent are good in adsorbability of waste gas and high in purifying rate, and don't cause secondary pollution to environment by themselves. The prepared adsorbent has good adsorption effect on various contaminants, is high in adsorption efficiency and easy to remove, is good in reuse effect, and has bright application prospects.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an adsorbent capable of removing toxic substances in waste gas and a preparation method thereof. Background technique [0002] In the production of modern chemical industry, pharmaceutical industry and fine chemical industry, some compounds are easy to produce a large amount of waste gas during the production process, some enterprises will directly discharge into the natural environment without taking any measures, and some enterprises will discharge into the environment through simple treatment , but these behaviors will harm the spontaneous combustion environment, and will also cause a lot of waste of resources, so how to maximize the recovery of resources and reduce the impact of toxic substances in the exhaust gas on the natural environment and the health of nearby residents. The traditional materials for adsorbing exhaust gas are mainly activated carbon, diatomaceous earth, molecu...

[0002] In the production of modern chemical industry, pharmaceutical industry and fine chemical industry, some compounds are easy to produce a large amount of waste gas during the production process, some enterprises will directly discharge into the natural environment without taking any measures, and some enterprises will discharge into the environment through simple treatment , but these behaviors will harm the spontaneous combustion environment, and will also cause a lot of waste of resources, so how to maximize the recovery of resources and reduce the impact of toxic substances in the exhaust gas on the natural environment and the health of nearby residents

The traditional materials for adsorbing exhaust gas are mainly activated carbon, diatomaceous earth, molecular sieve, etc., but there are disadvantages such as low adsorption capacity, significant decrease in adsorption performance in sweat atmosphere, decrease in adsorption capacity after regeneration, and high operating costs, making this kind of adsorbent currently unavailable. It has been well applied in the field of waste gas treatment
