Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas drainers, and in particular to a gas drainer with a self-cleaning device. Background Technology
[0002] Gas drainers are widely used in the steel industry for blast furnace gas, coke oven gas, converter gas, and mixed gas pipelines as the main equipment for removing water and impurities from gas pipelines. In 2018, the Ministry of Emergency Management of the People's Republic of China issued the "Safety Technical Regulations for Gas Drainers" AQ7012-2018, which clearly stipulates that solid debris deposited at the bottom of the drainer cylinder should be cleaned to ensure smooth drainage.
[0003] When it is necessary to clean impurities inside the gas drain, the operator needs to open the flange cover of the gas drain. However, the flange cover of the gas drain is mostly made of cast iron and other technical materials and is relatively large. Removing the flange cover is time-consuming, laborious, and poses a safety risk, making the cleaning operation of the gas drain quite inconvenient. Summary of the Invention
[0004] The purpose of this invention is to provide a gas drainer that facilitates the removal of impurities.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas drainer with a self-cleaning device, comprising a drainer body, wherein a perforated pipe is provided inside the drainer body, and a plurality of water spray holes are opened on the side wall of the perforated pipe, and the water inlet end of the perforated pipe extends through the side wall of the drainer body.
[0006] Furthermore, an outlet is provided at the end of the drain body away from the inlet end of the porous pipe, and several spray holes are inclined, with the spray holes inclined from the inlet end of the porous pipe toward the outlet end of the drain body. The inclined arrangement of the spray holes can push impurities inside the drain body toward the outlet end of the drain body while spraying water for cleaning.
[0007] Furthermore, the spray holes include a number of first spray holes, a number of second spray holes, and a number of third spray holes. The inclination angles of the first spray holes, second spray holes, and third spray holes are all different, thereby increasing the coverage of the sprayed water on the inner wall of the drain body and making the cleaning more thorough.
[0008] Furthermore, the first spray holes are divided into several groups, with each group of first spray holes evenly arranged along the circumference of the porous tube and sequentially arranged along the length of the porous tube; the second spray holes are also divided into several groups, with each group of second spray holes arranged along the circumference of the porous tube; the third spray holes are also divided into several groups, with each group of third spray holes evenly arranged along the porous tube; the groups of second spray holes and the groups of third spray holes are staggered between every two adjacent groups of first spray holes. This arrangement ensures that the spray holes at different angles are evenly distributed, resulting in more uniform spraying of the inner wall of the drainer body.
[0009] Furthermore, the diameter of the porous tube ranges from 10 mm to 219 mm, the number of a group of first injection holes is 6 to 36, and the number of a group of second injection holes and a group of third injection holes are both 5 to 30. The diameter of the porous tube is positively correlated with the number of first, second, and third injection holes. The larger the diameter of the gas drainer to be cleaned, the larger the diameter of the porous tube, and thus the greater the number of first, second, and third injection holes in each group on the porous tube.
[0010] Furthermore, the diameters of the first, second, and third injection holes all range from 1 mm to 12 mm.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. High-pressure water is injected into the perforated pipe. The high-pressure water is then sprayed out from the spray holes on the side wall of the perforated pipe and sprayed onto the inner wall of the drain body to achieve cleaning. The impurities after cleaning are discharged from the drain hole of the drain body along the water flow, thus completing the cleaning. Therefore, it is not necessary to remove the flange cover of the gas drain, which improves the convenience of cleaning the gas drain.
[0013] 2. The water spray holes are designed to be angled from the inlet end of the multi-hole pipe to the other end. This design allows the water sprayed from the water spray holes to clean the inner wall of the drain body while simultaneously pushing the mixture of water and impurities inside the drain body. This causes the water and impurities inside the drain body to flow further towards the outlet of the drain body, resulting in cleaner discharge of impurities. Attached Figure Description
