Device for prolonging service life of cloth bag through leak detector

Abstract

The invention provides a device for prolonging the service life of a cloth bag through a leak detector. A clean gas outlet blind plate valve and an ash conveying valve are respectively arranged at an inlet and an outlet in a conical casing. A lower part at the left side of the conical casing is sequentially provided with a lower inlet hole and a compressed air valve. A central part at the right side of the conical casing is sequentially provided with an upper inlet hole and a half-clean gas inlet blind plate valve. Each cloth bag internally provided with a keel bell mouth is vertically arranged between the upper inlet hole and the lower inlet hole of the conical casing. The cloth bags internally provided with the keel bell mouths are additionally provided with the leak detector. An upper plate and a lower plate of the leak detector are provided with detection holes which are matching with the number and the mouth dimension of the cloth bags. Detection tubs fixed on the lower plate are combined with the keel bell mouths of the cloth bags. Bolts for fixing a filtering material are arranged at two ends of the upper plate and the lower plate.

Description

technical field [0001] The invention relates to technical transformation, especially for eliminating the blind replacement and waste of the dry bag dust removal system, the design of the leak picker has excellent effect after use. Background technique [0002] The 5# hot blast stove in the old area of ​​the blast furnace branch is equipped with 1#-7# dry bag dust removal system. In the early stage, the box bag with a service life of two years was replaced as a whole in the early stage, that is, it needs to be replaced every two years. Box bags, through the inspection of the bags replaced on site, it is found that only 10.5% of the damaged bags are found, that is, there are 210 bags in a box, and the number of damaged bags is 20 at most, and the remaining bags can continue to be used for 1-2 years. The method of periodic box body bag replacement as a whole is obviously an inevitable result of waste of resources and increase of production cost. [0003] In order to achieve th...
