Abstract

The invention provides a blast furnace gas dehydrator. The blast furnace gas dehydrator comprises a shell body (10) and a filter mesh (20) arranged in the shell body (10), wherein a gas inlet (30) is formed in the bottom of the shell body (10), a gas outlet (40) is formed in the top of the shell body (10), and the gas inlet (30) and the gas outlet (40) are respectively located at the two sides of the filter mesh (20). The blast furnace gas dehydrator further comprises blowback openings (50), a blowback pipeline and a filter residue collection device (60), wherein the blowback openings (50) are formed in the shell body (10), and the blowback openings (50) and the gas outlet (40) are located at the same side of the filter mesh (20); the blowback pipeline is connected with the blowback openings (50); the filter residue collection device (60) is connected to the shell body (10), and the filter residue collection device (60) and the gas inlet (30) are located at the same side of the filter mesh (20). According to the blast furnace gas dehydrator provided by the invention, the problem in the prior art that the filter mesh of the blast furnace gas dehydrator is complicated to clean is solved effectively.

Description

technical field [0001] The invention relates to the technical field of dehydrators, in particular to a blast furnace gas dehydrator. Background technique [0002] Blast furnace gas is a by-product of iron-making blast furnace production. Because of its low calorific value, it is not easy to use directly. The nitrogen in it is separated by pressure swing adsorption, and the concentration of combustible components in it is increased, and it is directly used for heating furnace combustion. Very good economic and social benefits. [0003] Blast furnace gas contains dust, and after bag dust removal, it still contains 10mg / Nm 3 About dust (sometimes even greater than 10mg / Nm 3 ). The blast furnace gas is then sent to a dehydrator for further filtration to remove dust and moisture. [0004] In the process of purifying blast furnace gas, the capacity of the dehydrator to treat blast furnace gas is 66700Nm 3 / h, a large amount of dust enters the dehydrator every hour. Usually, ...
