The main task of the gas purification system is to make the gas quality (dust content, moisture, etc.) meet the requirements of gas pressurized transportation and gas user use, and strive for advanced and reasonable technology and economy. Coal gas generated in smelting, coking, sintering and other working sections of iron and steel enterprises often carries dust and other droplets of harmful substances. In order to prevent dust and liquid drops from being brought out along with the gas flow to affect other spaces, various dewatering and dust removing devices are generally designed and installed in the gas conveying process to separate the dust and the liquid drops from the gas flow.

As a coarse dust removal and dehydration device, the gravity type dust removal dehydrator is widely applied to dry and wet dust removal of iron and steel enterprises.

First embodiment

Referring to fig. 1, the present embodiment provides a gas dust-removing dehydrator 10, which is used for transferring gas and performing dust-removing and dehydrating processes on gas. The gas dust-removing dehydrator 10 can improve the dust-removing and dehydrating effects on the gas under the condition of ensuring the gas conveying efficiency.

Referring to fig. 1 and 2, the gas dust-removing dehydrator 10 includes a volume 100, a partition 200 and a partition net 300. The volume body 100 is provided with a cavity therein, and the cavity is used for transportation and transition of gas, that is, a transportation pipeline of gas is used for connecting the volume body 100 and is communicated with the cavity 110, so that the transportation pipeline can transport the gas into the cavity 110, and transport the gas to a designated place after transition through the cavity 110. In addition, the volume body 100 is provided with an air inlet 120 and an air outlet 130, the air inlet 120 and the air outlet 130 are both communicated with the cavity 110, and the air inlet 120 and the air outlet 130 are both used for connecting a gas conveying pipeline, so that the gas conveyed by the gas conveying pipeline can be guided into the cavity 110 through the air inlet 120, and the gas in the cavity 110 can be guided out of the cavity 110 through the air outlet 130, and the transition of the volume body 100 to gas conveying can be realized.

The baffle 200 and the separation net 300 are both disposed inside the cavity 110, and the baffle 200 and the separation net 300 are connected to each other and divide the cavity 110 into an inlet chamber 111 and an outlet chamber 112. The gas inlet cavity 111 is connected to the gas inlet 120, so that the gas introduced into the volume 100 through the gas inlet 120 can enter the gas inlet cavity 111. The gas outlet cavity 112 is communicated with the gas outlet, so that the gas entering the gas outlet cavity 112 can be guided out through the gas outlet 130. It should be noted that, in the present embodiment, after entering the gas inlet cavity 111 through the gas inlet 120, the gas can pass through the partition 300 and enter the inside of the gas outlet cavity 112.

In addition, in this embodiment, when the gas enters the gas inlet cavity 111 from the gas inlet 120, since the aperture of the gas inlet 120 is smaller than the inner diameter of the gas inlet cavity 111, that is, the flow area of the gas is suddenly increased, and further the flow speed of the gas is suddenly reduced, at this time, due to the action of its own gravity, particles with larger particle size, which are mixed in the gas, can be separated from the gas, and further, the effects of partial dust removal and dehydration are achieved. It should be noted that, the particulate matter herein refers to: solid dust, small water droplets, and other liquid particles.

Further, in the present embodiment, the intake port 120 is directed toward the partition 200. That is, when the gas is introduced through the gas inlet 120, the horizontally flowing gas directly impacts the partition board 200, which further reduces the flow velocity of the gas and changes the flow direction of the gas, and at this time, due to the action of the inertia force, some particles in the gas impact the partition board 200 to lose kinetic energy and fall to the bottom of the volume 100. When the obtained decelerated gas passes through the separation net 300, the gas can be fully contacted with the separation net 300, so that liquid particles in the gas can be attached to the separation net 300, and the separation net 300 adsorbing the liquid particles can infiltrate and agglomerate various particles in the gas, thereby further improving the dust removal and dehydration efficiency of the gas.

After the gas enters the gas inlet chamber 111 through the gas inlet 120, the gas impacts the partition plate 200 and is decelerated, so that a part of large particles in the gas can stall and fall to the bottom of the volume body 100. The decelerated gas passes through the screen 300, and after the gas is dedusted and dehydrated by the screen 300, the gas enters the gas outlet cavity 112. The gas entering the gas outlet cavity 112 can be guided out through the gas outlet 130, when the gas dust-removing dehydrator 10 is just put into use, the gas outlet 130 is arranged close to the top of the volume body 100, so that when the gas enters the gas outlet cavity 112, the gas can be accumulated in the gas outlet cavity 112, and the gas is guided out from the gas outlet 130 until the depth of the gas reaches the gas outlet 130, and the gas guided out through the gas outlet 130 can flow stably, so that the output of the gas can be stable.
