| titleOfInvention | Anti-splashing positive and negative pressure protector |
| abstract | The utility model relates to a positive negative pressure protector of anti-splash relates to biogas fermentation engineering technical field. Comprises a box body, wherein the box body is arranged in a closed manner, and the side wall of the box body is provided with an air inlet pipe connected with a biogas fermentation tank; the box body is internally provided with a clapboard which comprises a positive pressure chamber and a negative pressure chamber; the positive pressure chamber comprises a positive pressure pipe and a positive pressure chamber exhaust device, the positive pressure exhaust device comprises a main exhaust pipe and a rain-proof cap which are arranged at the top of the box body, and gas exhausted from the box body can only be exhausted through the main exhaust pipe; a first antifreezing solution filling device is arranged on one side of the positive pressure chamber, a negative pressure pipe is arranged in the negative pressure chamber, a rain-proof cap is arranged at the exhaust end of the negative pressure pipe, and a second antifreezing solution filling device is arranged on one side of the negative pressure chamber, so that the antifreezing solution can be filled through the device. The utility model can prevent the antifreeze from splashing to the outside of the negative pressure chamber or the box body when the positive pressure exhaust device exhausts, and prolong the service life of the positive and negative pressure protector; the antifreeze can be flexibly added, and the use is convenient. |
