During use, the traditional sludge waste gas treatment device is prone to incomplete treatment of hydrogen sulfide gas in the sludge waste gas, and the waste liquid generated after the sludge waste gas treatment is not treated and directly discharged, which is easy to cause environmental pollution. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a sludge waste gas treatment device, including a treatment box, the top of the treatment box is connected to an exhaust fan through an air pipe, the other end of the exhaust fan is connected to an air intake pipe through a gas flow sensor, one side of the treatment box is connected to a conduit through an electromagnetic flow valve, the other end of the conduit is sealed and connected to a copper sulfate storage tank, a vibration mechanism is installed on the outside of the treatment box, the vibration mechanism includes a hollow plate and a mounting column, one end of the outside of the hollow plate is fixedly connected to a drive motor, the output end of the drive motor is connected to a cam through a driving shaft, the other end of the mounting column is connected to a support seat through a spring, and the treatment box is also connected to a solenoid valve and an alkali solution storage tank through a connecting pipe.

[0006] Preferably, a discharge outlet is integrally formed at the bottom of the processing box, and a sealing plate is slidably connected to the bottom end of the discharge outlet. One end of the sealing plate is connected to a mounting plate via an electric push rod, and the output end of the electric push rod is fixedly connected to one end of the sealing plate, and the other end of the electric push rod is fixedly connected to one end of the mounting plate, and the other end of the mounting plate is fixedly connected to the outer surface of the processing box.

[0007] Preferably, a controller is fixedly connected to the middle of the exterior of the processing box, a pH sensor is installed below the controller, and a detection end of the pH sensor is located inside the processing box.

[0008] Preferably, one end of the gas pipe is located inside the processing box, the other end of the gas pipe is sealed connected to one end of the vacuum pump, one end of the gas flow sensor is sealed connected to the other end of the vacuum pump, and the other end of the gas flow sensor is sealed connected to one end of the air intake pipe.

[0009] Preferably, one end of the electromagnetic flow valve is sealed and connected to one side of the processing box and communicates with the interior thereof, and the other end of the electromagnetic flow valve is sealed and connected to one end of the conduit.

[0010] Preferably, one end of the driving shaft is rotatably connected to the inner wall of the hollow plate, the other end of the driving shaft is fixedly connected to the output end of the driving motor, the cam is fixedly connected to the middle of the driving shaft, one end of the spring is fixedly connected to the other end of the mounting column, the other end of the spring is fixedly connected to one end of the support seat, and four mounting columns are provided, which are fixedly connected at the four corners of the bottom of the processing box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model combines an air pipe, an air pump, a gas flow sensor, an air intake pipe, an electromagnetic flow valve, a conduit and a copper sulfate storage tank. When the sludge waste gas is treated, the controller first sets the amount of liquid outflow controlled by the electromagnetic flow valve each time according to the gas flow detected by the gas flow sensor. At this time, the air pump sucks the sludge waste gas through the air intake pipe, and then the waste gas is transported to the inside of the treatment box through the air pipe after being detected by the gas flow sensor. After the waste gas enters the inside of the treatment box, the hydrogen sulfide gas in the waste gas reacts with the copper sulfate solution in the treatment box, thereby solving the problem that part of the hydrogen sulfide gas cannot be decomposed during the preheating process when the hydrogen sulfide gas is decomposed by heating.

[0014] When the amount of gas entering the treatment box reaches the amount of liquid set by the electromagnetic flow valve, the controller will control the electromagnetic flow valve to open. At this time, the copper sulfate solution in the copper sulfate storage tank is transported to the inside of the treatment box through the conduit, so as to automatically add an appropriate amount of copper sulfate solution to the inside of the treatment box, thereby avoiding the phenomenon that the hydrogen sulfide gas reaction is not complete when the amount of hydrogen sulfide gas is greater than the amount of copper sulfate liquid;

[0015] When the exhaust gas is being processed inside the treatment box, the driving motor will drive the cam to rotate inside the hollow plate through the driving shaft, and then cooperate with the spring and the mounting column to make the treatment box vibrate as a whole, thereby improving the adequacy of the reaction between the exhaust gas and the copper sulfate solution inside the treatment box;

[0016] When the waste liquid inside the treatment box is being treated, the controller first detects the pH inside the treatment box through the pH sensor, and then controls the solenoid valve to open. At this time, the alkali liquid in the alkali liquid storage tank flows into the interior of the treatment box through the connecting pipe. When the value detected by the pH sensor is 6-7, the controller controls the solenoid valve to close and controls the electric push rod to operate. At this time, the electric push rod will drive the sealing plate to move out through the discharge port. At this time, the sediment and waste liquid in the treatment box will flow out directly, so as to neutralize the waste liquid in the treatment box, avoiding the pollution to the environment caused by the direct discharge of waste liquid with excessive acidity.
