Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of decarbonization liquid recovery, in particular to a decarbonization liquid recovery device. Background Art
[0002] In the decarbonization system of fertilizer plants, the separation of decarbonization liquid contained in the regeneration gas of decarbonization liquid has always been carried out by installing a separator at the regeneration gas outlet. The separator is filled with some plastic fillers, and the decarbonization liquid contained in the regeneration gas is separated by the fillers in the separator and directly discharged through the vent pipe. Because the gas flow is large and the flow rate is fast, the decarbonization liquid entrained in the gas cannot be completely separated by the regeneration gas separator. In actual use, the separation effect is not good. The riser pipe of the separator still entrains a lot of decarbonization liquid and is discharged. The decarbonization liquid lost every day is more than 10Kg, causing great economic losses. Utility Model Content
[0003] The utility model aims to provide a decarbonization liquid recovery device to solve the problem that a large amount of decarbonization liquid is entrained in the gas discharged from the separator, causing waste and economic losses.
[0004] Technical solution: The utility model provides a decarbonization liquid recovery device, including: an air riser, a liquid collecting tray, a supporting rib plate, a liquid collecting cover plate, and a liquid downcomer; the liquid collecting tray is arranged at the upper end outlet of the air riser; the supporting rib plate is arranged in the liquid collecting tray; the liquid collecting cover plate is a conical cover plate, which is arranged above the supporting rib plate, and a first liquid baffle plate is arranged below the liquid collecting cover plate; the liquid downcomer is arranged below the liquid collecting tray.
[0005] Furthermore, in the above-mentioned decarbonization liquid recovery device, the support rib plate is connected to the liquid collecting plate by welding, and the liquid collecting cover plate is connected to the support rib plate by welding. The welding connection improves the overall structural strength of the device.
[0006] Furthermore, in the above-mentioned decarbonization liquid recovery device, a stainless steel wire mesh is wound on the support rib plate, and the stainless steel wire mesh is wound 4-5 times. The wire mesh further decelerates and separates the formed droplets and flows down to the liquid collection tray, thereby improving the decarbonization liquid recovery effect.
[0007] Furthermore, in the above-mentioned decarbonization liquid recovery device, the first liquid baffle plate is welded at intervals below the liquid collecting cover plate, and the first liquid baffle plate is provided with several layers. The multi-layer liquid baffle plate can cause the decarbonization liquid in the discharged gas to collide and decelerate continuously for multiple times, and gather into droplets to flow to the liquid collecting tray.
[0008] Furthermore, in the above-mentioned decarbonization liquid recovery device, 8 supporting ribs are evenly distributed.
[0009] Furthermore, in the above-mentioned decarbonized liquid recovery device, the downcomer is located inside and below the liquid collecting cover plate, and there are two downcomers, which are respectively arranged on both sides of the riser.
[0010] Furthermore, in the above-mentioned decarbonization liquid recovery device, the liquid collecting tray is provided with a second liquid baffle plate which is designed to be bent inwards.
[0011] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the utility model describes a decarbonization liquid recovery device, after the regenerated gas is separated, the residual decarbonization liquid entrained in the gas is decelerated through continuous collisions between the gas riser, the liquid collecting cover plate and the multi-layer liquid baffle plate, and is further decelerated and separated through the wire mesh to form droplets that flow down to the liquid collecting plate, and the accumulated decarbonization liquid is then recovered to the underground tank through the downcomer and pumped into the system for recycling and use through the submersible pump. The device has a simple structure and a good recovery effect, reduces the loss of decarbonization liquid, protects the environment, reduces costs, and is highly practical.
