Detailed Implementation

[0023] Please see Figure 1 In a first aspect, embodiments of this utility model provide a chimney sewage pipe gas-water collection and reuse system, comprising: a chimney 1, a filter 2, and a gas-water separator 3, wherein the first port 2a of the filter 2 is connected to the chimney 1; the inlet 3a of the gas-water separator 3 is connected to the second port 2b of the filter 2; the outlet 3b of the gas-water separator 3 is connected to the downstream process; and the outlet 3c of the gas-water separator 3 is connected to the sewage purifier 4.

[0024] In the embodiments of this utility model, by installing a filter 2, a sewage purifier 4, and a gas-water separator 3 on the sewage pipe of the chimney 1, the gas and water can be effectively separated and recycled, thereby improving the technical problem that when the valve is fully open, exhaust gas will also leak out of the pipe while draining water, affecting the surrounding environment and causing certain safety hazards to on-site personnel and inspection personnel.

[0025] In one embodiment, a chimney exhaust pipe gas-water collection and reuse system further includes an exhaust gas pressurizing fan 5, which is connected to an exhaust port 3b. The exhaust gas pressurizing fan 5 can pressurize the exhaust gas, facilitating its discharge. Using a gas-water separator 3 and a wastewater purifier 4, water and gas are treated to render them harmless, reducing environmental pollution, effectively improving the on-site working environment, ensuring safety during hot work and inspection operations, and eliminating safety hazards.

[0026] A first valve is also installed between the exhaust gas booster fan 5 and the outlet 3b. The first valve can control the shutdown of the exhaust gas booster fan 5, which facilitates equipment maintenance.

[0028] In one embodiment, the centrifugal pump 7 is controlled by a Pump General T8. A first probe 61, a second probe 62, and a third probe 63 are installed in the water collection tank 6. The first probe 61 corresponds to the low liquid level, the second probe 62 corresponds to the medium liquid level, and the third probe 63 corresponds to the high liquid level. In addition to automatic control, the centrifugal pump 7 is also equipped with manual control, which can be switched at any time, making operation convenient and quick. This device has a one-button setting function, and protection can be set according to the specific pump power. The protection functions include overload, overcurrent, phase loss, and stall protection, preventing equipment failure and damage.

[0029] When the water level reaches the three levels of the high level probe in sequence from low, medium, and high, the pump starts automatically. When the water level reaches the low level in sequence from high, medium, and low, the pump stops automatically, thus realizing automatic control of the pump's start and stop.

[0030] In one embodiment, the centrifugal pump 7 is connected to the production water pipeline 8, and a check valve 9 is also provided between the centrifugal pump 7 and the production water pipeline 8. The check valve 9 can prevent water in the production water pipeline 8 from flowing back to the centrifugal pump 7.

[0031] Please see Figure 2 In one embodiment, a guide plate 31 is provided inside the gas-water separator 3.

[0032] When the gas-liquid mixture in chimney 1 enters the inlet 3a of gas-liquid separator 3 through the drain pipe, the internal baffle 31 prevents the exhaust gas pressurizing fan 5 from drawing the liquid into the pipe. The gas in gas-liquid separator 3 is drawn away by the exhaust gas pressurizing fan 5, and the liquid enters the sewage purifier 4 for purification. The upper end of gas-liquid separator 3 is connected by a flange for easy daily maintenance.

[0033] Please see Figure 3In one embodiment, the wastewater purifier 4 is provided with a first filter layer 41, a second filter layer 42, a third filter layer 43 and a fourth filter layer 44. The wastewater purifier 4 includes an inlet 4a and an outlet 4b. The outlet 4b is located at the bottom of the wastewater purifier 4, and the inlet 4a is located above the outlet 4b. The first filter layer 41, the second filter layer 42, the third filter layer 43 and the fourth filter layer 44 are stacked between the inlet 4a and the outlet 4b. The first filter layer 41 is located close to the outlet 4b.

[0034] In one embodiment, the first filter layer 41 is made of quartz sand and filter paper, the second filter layer 42 is made of activated carbon and filter paper, the third filter layer 43 is made of ceramic sand and filter paper, and the fourth filter layer 44 is made of granite pebbles.

[0035] This technical solution aims to achieve the recycling of gas and water resources through filter 2, gas-water separator 3, sewage purifier 4 and water collection tank 6. The exhaust gas is led to the outlet of exhaust gas pressurizing fan 5 through the exhaust port 3b and then sent to the downstream process. Gate valves are also installed at each equipment to ensure the normal operation of the on-site sewage pipe and make full use of exhaust gas and water.
