Embodiment 1

[0021] A novel environment-friendly dust collector, which includes a dust filter bag, and the dust filter bag is prepared according to the following process:

[0022] 1) Add zeolite and kaolinite to the crusher in turn for crushing, then mix with bentonite, and then grind to obtain a powder with a particle size of 200 mesh, which is material A; the mass of the zeolite, kaolinite and bentonite The ratio is 2:1:1;

[0023] 2) Add deionized water to the cationic starch, stir evenly to obtain a suspension, then add the material A obtained in step 1), stir at 300 rpm for 30 minutes, then let it stand for 6 hours, filter and collect the precipitate, and place the precipitate at 50°C Drying, and finally crushing to obtain material B; wherein, the mass ratio of cationic starch, deionized water and material A is 1:10:2;

[0024] 3) Add nano-silicon carbide, nano-diatomaceous earth, methacryloxypropyltrimethoxysilane and its deionized water into the stirring tank in sequence, and stir ...

Abstract

The invention belongs to the technical field of environmental protection, and discloses a novel environment-friendly dust collector which comprises a dust filter bag. The dust filter bag is prepared according to the process including the steps: 1) preparing a material A; 2) preparing a material B; 3) preparing a material C; 4) preparing a material D; 5) preparing the dust filter bag. The dust collector with the modified dust filter bag is environmentally friendly, pollution-free, high in filtering efficiency and long in service life, and has an important industrial application value.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a novel environmental protection dust collector. Background technique [0002] Dust collector is a device that separates dust from flue gas, called dust collector or dust removal equipment. The performance of the dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life and difficulty of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production. 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 co...
