Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal devices, and more specifically, particularly relates to an air inlet dust removal device for a pressure regulating valve. Background Art

[0002] In order to prevent dust from entering the pressure regulating valve and causing damage to the pressure regulating valve, a dust-proof net is usually installed at the air inlet of the existing pressure regulating valve. The gas is filtered through the dust-proof net, so that the dust in the air falls into the collection bin and enters the sedimentation bin through the inclined pipe to wait for unified cleaning.

[0003] For example, CN215887088U discloses an air inlet dust removal device for a blast furnace gas pressure regulating valve group, which includes a gas pipeline, a dust sedimentation chamber, a sedimentation inclined pipe and a dust bin; the gas pipeline includes a vertical pipe section and a horizontal pipe section that are connected, and a pressure regulating valve is provided on the horizontal pipe section; the dust sedimentation chamber is funnel-shaped and is connected to the lower end of the connection between the vertical pipe section and the horizontal pipe section; the sedimentation inclined pipe is arranged obliquely and is connected to the lower opening of the dust sedimentation chamber; the dust bin is connected to the lower opening of the sedimentation inclined pipe. This device can effectively reduce the dust content in the gas, effectively prevent the situation that the residual dust in the gas enters the pressure regulating valve group and punches through the valve, avoid the accidental situation of equipment damage and shutdown due to the large dust content in the blast furnace gas in the past, has the characteristics of simple structure, high dust removal efficiency, less residual dust in the gas, etc., improves the stability of production operation, and reduces the probability of failure.

It is necessary to regularly clean or replace the dust-proof net. When cleaning or replacing, the dust-proof net needs to be removed and reinstalled first, which not only causes a large labor burden on the staff, but also takes a long time, affecting the cleaning or replacement efficiency of the dust-proof net.

[0030] The specific usage mode and function of this embodiment: When gas enters the pressure regulating valve along the intake pipe 1, the dust filter plate 6 will filter the dust in the gas, so that the dust falls from the dust collection bin 2 into the dust settling bin 3. When the dust in the dust settling bin 3 is too much and needs to be unloaded, open the ash unloading valve, and then press the pressurizing air bag 303.
