Adsorption filtering agent for nano strontium titanate modified montmorilonite clay and preparation method therefor

Abstract

The invention discloses an adsorption filtering agent for nano strontium titanate modified montmorilonite clay. The dsorption filtering agent is prepared from the following raw materials in parts by weight: 70-80 parts of montmorilonite clay, 11-14 parts of coke powder, 15-20 parts of coal ashes, 2-4 parts of rosin, 1-3 parts of magnesium chloride, 1.1-2.4 parts of sodium metaphosphate, 0.6-0.9 part of antimonous oxide, 4.2-5.7 parts of nano strontium titanate, 0.4-0.8 part of a silane coupling agent YDH-151 and an appropriate amount of water. The adsorption filtering agent prepared by the preparation method has the characteristics of a rough and hard surface, a large specific surface area, high porosity, good adsorption filtering performance and low cost, the nano strontium titanate is loaded on the surface of the montmorilonite clay through a physical and chemical modifying method for decomposing organic pollutants into carbon dioxide and oxygen gas, so that harmful substances adsorbed on the montmorilonite clay are reduced, the service life of the adsorption filtering agent is prolonged, and the adsorption filtering agent is provided with a good waste gas filter function while being sprayed to a dust collector filter material and is suitable for being used in high temperature soot treatment.

Description

technical field [0001] The invention relates to the technical field of adsorption filter materials, in particular to an adsorption filter of nano strontium titanate modified montmorillonite clay and a preparation method thereof. Background technique [0002] With the rapid development of industrialization, the problem of air quality is becoming more and more serious. Especially in recent years, smog has seriously threatened people's health across the country, and the side effects caused by it have become increasingly serious. The culprits are domestic building materials, chemicals, For the smoke and dust discharged from kiln heads and kiln tails, calcium carbide furnaces, ferroalloy furnaces, etc. in metallurgical industries, the most commonly used dust removal equipment is the bag filter. The bag filter is a dry dust filter device. After the filter material is used for a period of time, due to effects such as screening, collision, retention, diffusion, and static electricit...

Problems solved by technology

However, in the actual operation process, the use of the first layer is not enough, resulting in low dust removal effect and serious wear and corrosion of the filter material after long-term use. There is an urgent need for an adsorption filter with high efficiency and multiple functions to be sprayed on the filter before the dust collector starts to work. The surface of the material is used as the first layer, which can not only improve the dust removal effect of the dust collector, but also filter and absorb the harmful exhaust gas discharged.
