Referring to fig. 1, in some embodiments of the present invention, the present embodiment provides a hot low pressure separator system for recovering hot low pressure gas, including a hot low pressure separator 100, a natural gas tank 200, and a recovery pipeline 300. The hot low pressure separator 100 has an outlet end 110; the natural gas tank 200 has an intake end 210; one end of the recycling pipe 300 is connected to the air outlet 110, and the other end of the recycling pipe 300 is connected to the air inlet 210.
The hot low-pressure gas generated by the hot low-pressure separator 100 enters the recycling pipeline 300 through the gas outlet end 110, passes through the recycling pipeline 300, reaches the other end of the recycling pipeline 300, and enters the natural gas tank 200 from the gas inlet end 210. That is, the hot low-pressure gas is recycled to the natural gas tank 200 along the recycling pipeline 300 and is utilized by the natural gas system, so that the hot low-pressure gas can be recycled to the natural gas system, thereby achieving the purposes of saving natural resources and avoiding resource waste.
In some embodiments of the present invention, the thermal low pressure separator 100 further has a liquid discharge end 120, the liquid discharge end 120 is disposed at the bottom of the thermal low pressure separator 100, one end of the liquid pipeline 130 is connected to the liquid discharge end 120, and the other end of the liquid pipeline 130 is connected to a liquid collecting tank 400. Not only the hot low-pressure gas but also the liquid product are generated in the hot low-pressure separator 100, and the liquid product is distributed in the lower half of the hot low-pressure separator 100 due to gravity, so the drain 120 is disposed at the bottom of the hot low-pressure separator 100 for draining the liquid in the lower half of the hot low-pressure separator 100. It can be understood that the liquid discharge end 120 is connected with a vertically downward liquid pipe 130, and the vertically downward liquid pipe 130 facilitates the discharge of the liquid, so as to avoid the liquid remaining in the liquid pipe 130, which may block the liquid pipe 130, and may corrode the liquid pipe 130, thereby affecting the liquid pipe 130. The liquid discharged from the liquid outlet end can be discharged into the liquid collection tank 400 through the liquid pipe 130.
In some embodiments of the present invention, it can be further understood that, in the thermal low pressure separator 100, besides the product of the thermal low pressure gas and the product of the liquid, a part of the gaseous product with lower density than the atmospheric density may be generated, and the gaseous product is collected in the upper half of the thermal low pressure separator 100, so the thermal low pressure separator 100 further has an exhaust port 140, the exhaust port 140 is disposed at the top of the thermal low pressure separator 100, and the exhaust port 140 is connected to the exhaust valve 141. In order to maintain the pressure of the hot low-pressure separator 100 stable, the exhaust valve 141 at the exhaust port 140 is opened to discharge the generated gaseous substances out of the hot low-pressure separator 100. In addition, if the hot low pressure separator 100 fails during operation, emergency maintenance is required. To ensure that the pressure in the low-pressure thermal separator 100 is at a safe level, the exhaust valve 141 is opened to exhaust the pressure medium in the low-pressure thermal separator 100, so that the pressure in the low-pressure thermal separator 100 is restored to a value close to atmospheric pressure, thereby ensuring safety.
In some embodiments of the present invention, a first control valve 310 is further disposed on the recycling pipe 300, and the first control valve 310 is disposed at the air outlet end 110. The first control valve 310 is disposed on the recycling pipe 300, and the recycling pipe 300 can be connected or blocked by opening or closing the first control valve 310 by operating a valve rod of the first control valve 310. On one hand, when the output side of the first control valve 310 fails or stops working, the first control valve 310 needs to be closed to isolate the hot low pressure environment in the hot low pressure separator 100, so as to avoid the damage and destruction to the hot low pressure separator 100 caused by safety accidents or hot low pressure gas backflow phenomenon during maintenance failure.
In some embodiments of the present invention, a pressure gauge 320 is disposed at the gas inlet 210 of the natural gas tank 200, and a check valve 330 is disposed between the pressure gauge 320 and the gas inlet 210. Still be provided with pressure sensor (not shown in the figure) on recovery pipeline 300, pressure sensor will acquire the pressure value feedback in recovery pipeline 300 and give back to manometer 320, and manometer 320 makes things convenient for the technical staff to read and understand the visual reaction of pressure value in recovery pipeline 300 on manometer 320's panel board to make technical staff know the environment in recovery pipeline 300, and then can judge the inside pressure environment of hot low pressure separator 100. Meanwhile, the pressure environment in which the hot low-pressure gas enters the natural gas tank 200 can also be known. The check valve 330 provided between the pressure gauge 320 and the intake end 210 is to prevent the hot low-pressure gas from entering the natural gas tank 200 at a lower pressure than the natural gas tank 200 and causing a natural gas backflow phenomenon, so that the hot low-pressure gas cannot enter the natural gas tank 200, and the check valve 330 allows the hot low-pressure gas to pass therethrough, but does not flow from the natural gas tank 200 side to the hot low-pressure separator 100 side.
Referring to fig. 2, in some embodiments of the present invention, the recovery pipe 300 and the intake end 210 are connected by a flange 340, and the flange 340 is provided with a threaded mounting hole 341. On the recovery pipeline 300 side of the flange 340, a threaded mounting hole 341 is formed in the flange 340, threads matched with the threaded mounting hole 341 of the flange 340 are also formed in one end, connected with the flange 340, of the recovery pipeline 300, the recovery pipeline 300 is communicated with the flange 340 through a threaded structure, the flange 340 and the natural gas tank 200 are of an integrated structure on the air inlet end 210 side of the natural gas tank 200, the flange 340 on the natural gas tank 200 is connected with the flange 340 connected to the recovery pipeline 300 in a matched mode, and the two flanges 340 can be fastened and connected through studs or bolts.
It will be appreciated that a sealing ring 342 is provided between the two flanges 340. The recovery pipeline 300 and the natural gas tank 200 are connected by the flange 340, and because the heat low-pressure gas exists in the recovery pipeline 300, the connection structure of the flange 340 is required to meet the requirement of high air tightness, and the heat low-pressure gas is prevented from leaking into the atmosphere, so that the waste of resources is caused.
In some embodiments of the present invention, a second control valve 131 is disposed on the liquid pipe 130. The second control valve 131 is a floating ball trap or a steam trap. The floating ball type drain valve has a very obvious effect of preventing the hot low-pressure gas from discharging liquid substances in a steam heating system of the hot low-pressure separator 100, and can ensure that the hot low-pressure separator 100 achieves the highest working efficiency. The working principle of both steam traps and floating ball traps is choke and drain, and further explanation of steam traps is omitted herein. It should be noted, however, that the two valves described above should be generally horizontally mounted in the fluid line 130.
In some embodiments of the present invention, the outer walls of the recovery conduit 300 and the fluid conduit 130 are each covered with an insulating jacket (not shown). It can be understood that the product of the hot low-pressure separator 100, the hot low-pressure gas and the liquid, can absorb enough heat in the hot low-pressure separator, resulting in higher temperature of the hot low-pressure gas and the liquid, so that the temperature of the pipe wall of the recovery pipe 300 and the temperature of the pipe wall of the liquid pipe 130 can be higher, and therefore, the outer walls of the recovery pipe 300 and the liquid pipe 130 are wrapped with heat-insulating sleeves to isolate the pipe wall with higher temperature, thereby avoiding the safety accidents of burning and scalding.
The present embodiment has been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
