Abstract
The invention discloses a method for recycling a cloth bag of a limekiln powder dust remover, comprising the steps as follows: (1) the inner and outer sides of the cloth bag of the used limekiln powder dust remover are rapped and beaten; (2) the inner and outer sides of the cloth bag are washed repeatedly by a high pressure water jet; (3) the cloth bag is dipped in hydrochloric acid solution with mass percent concentration of 2.3-3.37% for 8-20 hours; (3) the dipped cloth bag is taken out from soak solution, and the inner and outer sides of the cloth bag are washed by the high pressure water jet; (5) the cloth bag is dried in the sun naturally. The air perm of the cloth bag treated by the method of the invention can meet the requirement; therefore, the cloth bag can be used repeatedly and save production costs.
Description
Technical field
The present invention relates to a kind of recovery method, relate in particular to a kind of cloth bag recovery method of lime burner powder precipitator.
Background technology
The ash furnace powder precipitator is installed on the ash furnace exit in the soda ash production process, is used to collect calcium carbonate and decomposes the calcium oxide flying dust that the back generates, and the cloth bag of this ash furnace powder precipitator is of a size of 980X3500mm, every cloth bag is worth 800 yuan.Owing to there are not effectively to clean the means that reclaim cloth bag, cloth bag is scrapped processing usually at present; Also have and utilize 5% Xi sulfuric acid immersion 24 hours, the flushing of high pressure river to handle cloth bag, harden, cause Air permenbility can't reach requirement but the result is a cloth bag.
Summary of the invention
The object of the present invention is to provide a kind of cloth bag recovery method that makes a kind of lime burner powder precipitator that cloth bag can use repeatedly.
The present invention is achieved by the following technical programs.
The cloth bag recovery method of a kind of lime burner powder precipitator of the present invention, it may further comprise the steps:
(1) knocks the inside and outside two sides of the cloth bag of patting used ash furnace powder precipitator;
(2) wash the inside and outside two sides of described cloth bag repeatedly with giant;
(3) be that the hydrochloric acid solution of 2.3%-3.37% soaked described cloth bag 8-20 hour with mass percent concentration;
(4) cloth bag after the described immersion is taken out from soak, wash two sides inside and outside the described cloth bag repeatedly with giant;
(5) dry naturally standby.
Adopt the cloth bag after inventive method is handled to reach the Air permenbility that regulation requires, thereby can use repeatedly, save producing cost.
The specific embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
The cloth bag recovery method of a kind of lime burner powder precipitator of the present invention, it may further comprise the steps: (1) knocks the inside and outside two sides of the cloth bag of patting used ash furnace powder precipitator.(2) wash the inside and outside two sides of described cloth bag repeatedly with giant.(3) be that the hydrochloric acid solution of 2.3%-3.37% soaked described cloth bag 8-20 hour with mass percent concentration, if described concentration of hydrochloric acid solution is lower than 2.3%, be difficult for the dust that adheres on the cloth bag is cleaned up, if described concentration of hydrochloric acid solution is higher than 3.37%, not only wastes hydrochloric acid and also cause the cloth bag corrosion to be hardened easily.Soak time can guarantee that at 8-20 hour cloth bag has air permeability and good.(4) cloth bag after the described immersion is taken out from soak, wash inside and outside the described cloth bag two sides repeatedly to remove catabolite and to eliminate the corrosion of hydrochloric acid solution cloth bag with giant.(5) dry naturally standby.Described water can be river, can save cost like this.
