Description

Automatic cleaning device for liquid spraying filter element of gas pressurizer

Technical Field

The utility model relates to a coal gas adds press hydrojet filter core self-cleaning device.

Background

The steel industry, as an important group part of economic development in our country, has carbon dioxide emissions accounting for 12% of the total emissions each year, and this proportion still shows an increasing trend. The low-carbon metallurgical engineering technology is the mainstream trend of the development of the metallurgical engineering at present, the oxygen blast furnace has the process characteristics of low carbon, environmental protection and high efficiency, the hydrogen-rich smelting is realized in 8 months in 2021, the pressurized coke oven gas is successfully injected at the blast furnace tuyere, the fuel ratio is greatly reduced, and the economy and the function of energy conservation and emission reduction of the traditional blast furnace are subversive. As a part of Baoku low-carbon metallurgy, in order to accelerate the blast furnace to spray the coke oven gas to realize the industrial test target of hydrogen metallurgy, eight-steel company starts to perform hydrogen-rich industrial test in an Ou smelting furnace which is not the traditional smelting process, but for the change of the coke oven gas sprayed by a gas pressurizer along with seasons and climates, substances which can be separated out in the coke oven gas are easy to separate out and then block a filter screen, which becomes a technical difficulty.

Disclosure of Invention

An object of the utility model is to provide a coal gas adds press hydrojet filter core self-cleaning device can realize the quick switch-over of system, washs fast, has avoided the frequent machine that jumps of coal gas adding press, and the technological bottleneck that high-power motor frequently started effectively protects the smooth operation of coal gas adding press.

The technical scheme of the utility model be, a coal gas presser hydrojet filter core self-cleaning device, including wasing the casing, wash the casing and be cylindrical, vertical even interval is setting up four admission valves on wasing the lateral wall of casing, is connecting a side intake valve through the check valve on wasing the end wall of casing, four admission valves and side intake valve all connect a steam intake pipe, are connecting two blowoff valves on wasing another lateral wall of casing, the effluent water sump is being connected to the blowoff valve.

The utility model discloses can realize the quick switch-over of system, wash fast, avoid the frequent machine that jumps of coal gas presser, the technological bottleneck of the frequent start-up of high-power motor effectively protects coal gas presser even running.
