Waste gas purification device for garbage heat treatment

The invention discloses a waste gas purification device for garbage heat treatment, and relates to the technical field of waste gas purification, the waste gas purification device comprises a fixed seat, the top of the fixed seat is fixedly connected with a purification machine body, the outer surface of the purification machine body fixedly communicates with a first gas inlet pipe, and the upper surface of the fixed seat is fixedly connected with a second gas inlet pipe. The first electric contact and the second electric contact are close to each other and make contact with each other, so that a worker can quickly know the condition that the treating fluid in the liquid storage tank is insufficient through an alarm signal, and the treating fluid can be quickly added, and the problem that the worker cannot timely discover and supplement the treating fluid in the liquid storage tank is solved. The external pump body idles due to the fact that liquid cannot be pumped, so that an impeller of the pump body is not
