Novel tubular-type deduster and high temperature-resistant high-precision high-ventilating polytetrafluoroethylene fiber tube used for preparing deduster

Abstract

The invention relates to a novel tubular-type deduster. The novel tubular-type deduster is characterized by comprising several PTFE membrane pipes (1), one ends of the several PTFE membrane pipes (1)are fixed through pouring by a sealed glue, and the other ends of the several PTFE membrane pipes (1) are sealed. The novel tubular-type deduster has good dust processing capability, and the high temperature-resistant high-precision high-ventilating polytetrafluoroethylene fiber tube used for preparing deduster is used for preparing the deduster.

Description

technical field [0001] The invention relates to a novel tubular dust collector and a high-temperature-resistant, high-precision, high-breathability polytetrafluoroethylene fiber membrane tube used for preparing the dust collector. It is mainly used in gas-solid separation, dust removal in cement plants, flue gas dust removal, and boilers. Exhaust gas dust removal and other fields. Background technique [0002] In recent years, with the rapid development of the economy, metallurgical steelmaking electric furnaces and boilers fueled by raw coal have increased a lot. The air pollutants emitted by these furnaces have caused great harm to the surrounding environment, including nitrogen oxides, sulfides and dust Etc. Therefore, while removing acid gas, it is very necessary to remove particulate matter from dusty gas in order to reduce air pollution and avoid smog. [0003] At present, the dust removal technology mostly uses the bag filter device, which is a dry dust filter device...

AI Technical Summary

Problems solved by technology

[0006] (2) The material of the bag filter is relatively hydrophilic, but some flue gas contains more water, or the dust carried by it has strong hygroscopicity, which often causes the filter bag to stick and block the filter material

[0007] (3) The filter materials of the bag filter are relatively small, and the quality is not good, especially the filter bags at high temperature, and the flue gas is highly corrosive, and some have to be replaced in just a few months. bags, which increases operating costs and maintenance workload, and brings inconvenience to users

[0008] (4) The size of the bag filter is generally large, and the specific surface area of ​​the filter is small, which increases the size of the main equipment

[0009] (5) Some types of bag filter workers have poor working conditions, and when checking and replacing filter bags, they need to enter the box
