Description

Technical Field

[0001] This utility model relates to the field of brine extraction and cavity creation technology in gas storage facilities, specifically to an automatic sewage discharge system for wind and solar power generation in brine extraction wells. Background Technology

[0002] In the process of brine extraction and cavity construction in a salt cavern gas storage facility, the surface technology of the brine extraction well site includes brine extraction trees and their inlet and outlet pipelines, and square well pools. The functions of the square well pools are: first, to collect rainwater; second, to collect brine overflowing from the brine extraction trees (due to corrosion of the brine extraction tree equipment, there is often a situation where brine seeps out and overflows into the square well pools), thus avoiding pollution of the surrounding environment; and third, to facilitate daily inspections and well repair and logging operations.

[0003] Currently, the method for treating the sludge (including overflowing brine and rainwater) in the well pits is to pump the sludge into tank trucks and then have it treated by a wastewater treatment plant. This method requires paying additional wastewater treatment fees to the wastewater treatment plant, is frequent and costly; and if the tank trucks are not delivered in time, the sludge in the well pits may not be discharged in time, causing the sludge to overflow and pollute the environment. Utility Model Content

[0004] The purpose of this invention is to solve the problem of water accumulation in the square well pool of brine wells in salt cavern gas storage facilities, as described in the prior art, and to provide an automatic sewage discharge system for wind and solar power generation in brine wells.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automatic sewage discharge system for brine well wind and solar power generation, including a brine tree and a brine tree inlet pipeline and a brine tree outlet pipeline connected to it, a square well pool and a discharge pipeline; wherein the suction end of the discharge pipeline is placed in the square well pool, and its discharge end is connected to the brine tree outlet pipeline, and a sewage pump and its control system are installed on the discharge pipeline, the energy of the sewage pump and its control system comes from the wind and solar hybrid power generation system connected to it; the wind and solar hybrid power generation system includes integrated photovoltaic power generation equipment and wind power generation equipment.

[0006] Furthermore, the drainage pipeline is equipped with two pump sets, one in use and one in standby, which have the same structure and are set in parallel. Each pump set includes a one-way check valve, a sewage pump body, and a shut-off valve in the direction from the suction end to the discharge end. The connecting pipeline from the shut-off valve is merged into one, which is equipped with a drainage pipeline pressure gauge and a drainage pipeline one-way check valve. The end of the merged connecting pipeline is connected to the above-mentioned brine tree discharge pipeline. The suction ends of the two pump sets extend into the above-mentioned square well pool, and their installation heights are the same.

[0007] Furthermore, each pump unit pipeline is also equipped with a basket filter, located on the connecting pipeline on the suction side of the aforementioned one-way check valve.

[0008] Furthermore, a liquid level sensor is installed inside the square well pool, which is connected to the aforementioned sewage pump control system via a line or signal.

[0009] Furthermore, the sewage pump control system can also be connected to a mobile phone and / or computer via wireless signal.

[0010] Furthermore, an inlet control valve and an inlet pressure gauge are connected in series on the brine tree inlet pipeline; an outlet pressure gauge and an outlet control valve are connected in series on the brine tree outlet pipeline; and the outlet end of the outlet pipeline is connected to the outlet pipeline on the outlet side of the outlet control valve.

[0011] Compared with existing technologies, this utility model has the following advantages: The utility model has a simple structure and, for the first time, combines the drainage of the square well pool with the sap output from the brine-producing tree. A water pump injects the accumulated water from the square well pool into the brine-producing tree's sap output pipeline, which flows together with the extracted brine into the gas storage facility for treatment. This ensures timely drainage, prevents the brine-producing tree equipment from being submerged in water, avoids losses caused by corrosion of the tree itself, equipment, and pipelines, and reduces the cost and frequency of water treatment. Furthermore, the water pump integrates solar photovoltaic and wind power generation, eliminating the need for separate wiring, and offers advantages such as being environmentally friendly and having low maintenance costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1 As shown, an automatic sewage discharge system for brine well wind and solar power generation includes a brine well 1 and connected to it by a brine well inlet pipeline 100, a brine well outlet pipeline 200, a square well pool 2, and a drainage pipeline 300. The square well pool 2 is located on the ground below the brine well 1, facilitating daily inspection, well repair, and logging operations. The brine well 1 can adopt a conventional technical structure from the prior art. The brine well inlet pipeline 100 is connected to the inlet side of the brine well 1 and includes an inlet pipeline control valve 101 and an inlet pipeline pressure gauge 102 connected in series through a connecting pipeline. The brine well outlet pipeline 200 is connected to the outlet side of the brine well 1 and includes an outlet pipeline pressure gauge 103 and an outlet pipeline control valve 104 connected in series through a connecting pipeline. The outlet end of the brine well outlet pipeline 200 is connected to the gas storage station processing system.

[0015] The specifications of the aforementioned square well pool 2 are set according to actual production needs, such as a square cement pool of 1.8m×1.8m×1.8m. The suction end of the aforementioned drainage pipeline 300 is placed inside the aforementioned square well pool 2. The drainage pipeline 300 includes two pump sets (one in use and one in standby, operating alternately). The two sets have the same structure and are arranged in parallel. Each pump set includes a basket filter 306, a one-way check valve 301, a sewage pump 302 body, and a shut-off valve 303, which run from the suction end to the discharge end. The connecting pipes from the shut-off valve 303 of the two pump sets are merged into one drainage pipeline, on which a drainage pipeline pressure gauge 304 and a drainage pipeline one-way check valve 305 are installed in sequence. The end of the merged connecting pipe is connected to the aforementioned brine tree discharge pipeline 200, located on the discharge side of the discharge pipeline control valve 104. The suction end connecting pipes of the two pump sets extend into the aforementioned square well pool 2, and their installation heights are the same. A funnel-shaped outward expansion water collection end can be installed. The sewage pump 302 in the two pump sets mentioned above is equipped with a sewage pump control system 3, which can be a user-friendly stainless steel integrated control cabinet, and can realize automatic control of the opening and closing of the sewage pump 302. The integrated cabinet of the sewage pump control system 3 is also equipped with a wireless signal output terminal 8, which can be connected to a mobile phone and / or computer via signal to view the system operating status, system faults, water level, charging status and battery power in real time.

[0016] A liquid level sensor 5 is also fixedly installed in the aforementioned square well pool 2, which can monitor the water level in the square well pool 2 in real time. It is connected to the aforementioned sewage pump control system 3 via signal or line, so as to facilitate the automatic start and stop of the sewage pump 302.

[0017] The power of the sewage pump control system 3 comes from the wind-solar hybrid power generation system 4 connected to it. The wind-solar hybrid power generation system 4 includes an integrated solar photovoltaic power generation device 6 and a wind power generation device 7. The solar photovoltaic power generation device 6 has a capacity of 150W / h, and the wind power generation device 7 has a capacity of 400W / h.

The wind-solar hybrid power generation system 4 has its own power input-output converter, and its overall output voltage is AC220V and the power is 1000W.

[0018] The specific working principle is as follows: The square well pool 2 stores rainwater, overflowing brine, and other accumulated liquids. When the liquid level sensor 5 detects that the liquid level exceeds half the depth of the square well pool 2 or a fixed set value, it transmits the monitoring signal to the aforementioned sewage pump control system 3. The sewage pump control system 3 then controls one of the pump sets to start operation, discharging the accumulated liquid to the brine tree outlet pipeline 200. The operating power of the sewage pump 302 is capable of discharging 2m³ of sewage. 3 / h. When the liquid level sensor 5 detects that the liquid level has dropped to about 10% of the depth of the square well pool 2, the sewage pump control system 3 controls the sewage pump 302 to shut down. The aforementioned wind-solar hybrid power generation system 4 can also power the remote electronic inspection equipment installed on the brine tree 1, enabling real-time inspection of the brine tree 1.
