Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic biogas water seals for water treatment, and particularly discloses a water treatment anaerobic biogas water seal device. Background Art

[0002] In wastewater treatment, anaerobic biochemical treatment involves the conversion of organic matter into gases such as methane and carbon dioxide through the metabolism of anaerobic microorganisms (including facultative and obligate anaerobes) under anaerobic conditions. This process is also known as anaerobic digestion or anaerobic biological treatment technology.

[0003] Biogas is a clean, renewable energy source. Under normal circumstances, biogas undergoes chemical desulfurization and is then transported to power plant boilers for incineration and power generation. During maintenance of the water treatment chemical desulfurization tower or power plant boiler shutdown, the water treatment biogas is transported via pipelines to a biogas flare for emergency combustion. To achieve this, a biogas flame arrester is required on the biogas pipeline before it enters the biogas flare to prevent the flame from propagating backwards in the pipeline under abnormal circumstances, thereby avoiding biogas combustion accidents within the pipeline. Existing mechanical flame arresters, however, often clog and are difficult to clean during actual use, posing hidden dangers during operation and maintenance.

[0004] To solve the above problems, there is a biogas water sealer on the market. A certain amount of liquid is set in the biogas water sealer, and the biogas inlet pipe extends below the liquid level of the biogas water sealer. The biogas enters below the liquid level through the inlet pipe and is then discharged through the outlet pipe.

[0005] However, the liquid level in the aforementioned biogas water seal gradually decreases during use, requiring timely water replenishment. Failure to do so can easily cause flames to propagate in the opposite direction, leading to accidents. Furthermore, the biogas in the existing biogas water seal flows directly out of the outlet pipe after flowing below the liquid level, increasing the water content in the biogas and hindering subsequent combustion of the biogas flare. Utility Model Content

[0006] In response to the above-mentioned deficiencies in the prior art, the present invention provides a water treatment anaerobic biogas water seal device to solve the problem that the liquid level in the biogas water seal gradually decreases during use and needs to be monitored and replenished with water in a timely manner. If the water is not replenished in time, it is very easy to cause the flame to propagate in the reverse direction, resulting in accidents.

[0007] In order to achieve the above purpose, the technical solution of the utility model is:

[0008] A water seal device for anaerobic biogas treatment includes a tank body containing liquid, an air inlet pipe disposed at the top of the tank body with its end disposed below the liquid level, an air outlet pipe disposed at the top of the tank body, a water inlet pipe disposed on the side wall of the tank body, and an overflow port disposed on the side wall of the tank body; the overflow port is connected to an overflow pipe; the overflow pipe extends from one end of the overflow pipe away from the tank body to the bottom of the overflow tank; a drain pipe is disposed on the upper side wall of the overflow tank; the lower end of the overflow port is higher than the lower end of the air inlet pipe; and the drain pipe is disposed below the liquid level. During use, the water inlet pipe always maintains the flow of liquid water, and the liquid water in the tank body flows into the overflow tank through the overflow port and the overflow pipe, and then flows out through the drain pipe at the top of the overflow tank. This can maintain a stable liquid level in the tank body, eliminates the need for monitoring, and avoids accidents.

[0009] Preferably, the connection between the water inlet pipe and the tank body is higher than the liquid level in the tank body; the water inlet pipe is arranged in an L shape as a whole; and the lower end of the water inlet pipe is located at the bottom of the tank body. This ensures the stability of water inflow, prevents the liquid level from shaking and causing the lower end of the air inlet pipe to leak out of the liquid level, and improves safety.

[0010] Preferably, a sewage pipe is provided on the side wall of the bottom of the tank body to facilitate cleaning of the tank body during maintenance.

[0011] Preferably, a gas-water separation mechanism is provided at the connection between the gas outlet pipe and the tank body; the gas-water separation mechanism is provided above the liquid surface, which can reduce the water content in the biogas and ensure the subsequent combustion of the biogas torch.

[0012] Preferably, the gas-water separation mechanism includes a conical tube fixedly mounted at the end of the outlet pipe; the conical tube is in the form of a truncated cone with open ends; the smaller end of the conical tube is positioned away from the outlet pipe; and a baffle is coaxially fixedly mounted below the conical tube. Biogas is deflected by the baffle before being discharged through the conical tube, increasing contact between the biogas and the baffle, allowing water in the biogas to condense and drip, thereby reducing the water content of the biogas.

[0013] Preferably, the baffle is arranged in a bamboo hat shape as a whole, and the top end of the baffle is arranged toward the outlet pipe, so as to further increase the contact between the biogas and the baffle.

[0014] Preferably, the upper end surface of the baffle is fixed on the closing tube through a support rod.

[0015] The beneficial effects of the utility model are:

[0016] 1. When in use, the water inlet pipe always keeps liquid water flowing in. The liquid water in the tank body flows into the overflow tank through the overflow port and overflow pipe, and then flows out through the drain pipe on the upper part of the overflow tank. It can keep the liquid level in the tank body stable, without the need for monitoring, and avoid the occurrence of accidents.

[0017] 2. The setting of the gas-water separation mechanism can reduce the water content in the biogas and ensure the subsequent combustion of the biogas torch. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1

[0026] like Figure 1 、 2 As shown, a water seal device for anaerobic biogas treatment includes a tank body 1, in which liquid is placed. An air inlet pipe 2 with an end portion arranged below the liquid level 9 is provided on the top of the tank body 1. An air outlet pipe 3 is also provided on the top of the tank body 1. A water inlet pipe 4 is provided on the side wall of the tank body 1. An overflow port 5 is provided on the side wall of the tank body 1. The overflow port 5 is connected to an overflow pipe 6. The overflow pipe 6 extends from one end of the tank body 1 to the bottom of an overflow tank 7. A drain pipe 8 is provided on the upper side wall of the overflow tank 7. The lower end of the overflow port 5 is higher than the lower end of the air inlet pipe 2. The drain pipe 8 is arranged below the liquid level 9. When in use, the water inlet pipe 4 always keeps liquid water flowing in. The liquid water in the tank body 1 flows into the overflow tank 7 through the overflow port 5 and the overflow pipe 6, and then flows out through the drain pipe 8 on the upper part of the overflow tank 7. This can keep the liquid level in the tank body 1 stable, eliminate the need for monitoring, and avoid accidents.

[0027] In the above arrangement, the connection between the water inlet pipe 4 and the tank body 1 is higher than the liquid level 9 within the tank body 1; the water inlet pipe 4 is generally L-shaped; and the lower end of the water inlet pipe 4 is located at the bottom of the tank body 1. This ensures stable water inflow and prevents swaying of the liquid level 9 that could cause leakage from the lower end of the air inlet pipe 2, thereby improving safety. A drain pipe 10 is installed on the bottom sidewall of the tank body 1 to facilitate cleaning of the tank body 1 during maintenance.

[0028] Example 2

[0029] Based on Example 1, a gas-water separation mechanism is provided at the connection between the gas outlet pipe 3 and the tank body 1; the gas-water separation mechanism is provided above the liquid level 9, which can reduce the water content in the biogas and ensure the subsequent combustion of the biogas torch.

[0030] Among them, the gas-water separation mechanism includes a closing pipe 11 fixedly arranged at the end of the outlet pipe 3; the closing pipe 11 is a truncated cone shell with upper and lower ends open; the small diameter end of the closing pipe 11 is arranged away from the outlet pipe 3; and a baffle 12 is fixedly arranged below the closing pipe 11. After the biogas is deflected by the baffle 12, it is discharged from the closing pipe 11, which increases the contact between the biogas and the baffle 12, and the moisture in the biogas can condense and drip, reducing the moisture content in the biogas. The baffle 12 is arranged in a conical shape as a whole, and the top of the baffle 12 is arranged toward the outlet pipe 3, further increasing the contact between the biogas and the baffle 12. The upper end surface of the baffle 12 is fixedly set on the closing pipe 11 by a support rod 13.
