Description

Technical Field

[0001] The utility model relates to the field of waste gas purification, in particular to a fume waste gas purification device. Background Technique

[0002] When food processing factories are processing, they often generate waste gas with fumes. These waste gases cannot be directly discharged into the atmosphere, which will cause pollution to the atmosphere. It is necessary to separate the fumes. The gas with fumes produced by high-temperature processing will condense into an oil-water mixture after encountering cold fog, and then the oil stain can be separated by precipitation. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fume waste gas purification device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A fume waste gas purification device, including a bottom plate, a processing tank is arranged on the upper side of the bottom plate. An air inlet cavity and a condensation cavity are arranged in the processing tank. A threaded block is arranged at the upper end of the bottom plate. The threaded block is threadedly connected with a sealing cover. A spray pipe is fixedly connected inside the sealing cover. One end of the spray pipe extends into the condensation cavity, and the spray pipe is provided with a plurality of spray holes. A cold water pump is fixedly connected to the rear side of the upper end surface of the bottom plate. A water inlet pipe is fixedly connected between the cold water pump and the upper end surface of the bottom plate. The cold water pump can pump cold water into the spray pipe through the water inlet pipe. A sedimentation tank is fixedly connected to the front side of the upper end surface of the bottom plate. A sewage discharge pipe is fixedly connected between the sedimentation tank and the lower end of the processing tank. The sewage discharge pipe communicates with the sedimentation tank and the condensation cavity, so that the fume waste gas flowing through the condensation cavity can be condensed by the cold water mist sprayed from the spray holes and then flow into the sedimentation tank through the sewage discharge pipe for sedimentation and stratification.

[0005] Advantageously, the processing tank is provided with a vacuum heat preservation cavity, and the vacuum heat preservation cavity can keep the temperature of the condensation cavity, enhancing the effect of fume condensation in the condensation cavity;

[0006] Advantageously, a support frame is fixedly connected to the side wall of the processing tank, and the lower end surface of the support frame is fixedly connected to the upper end surface of the bottom plate;

[0007] Advantageously, an air inlet pipe communicating with the air inlet cavity is arranged on the front side of the processing tank. The fume waste gas generated by food processing is introduced into the air inlet cavity through the air inlet pipe and then flows downward through the condensation cavity for condensation;

[0008] Beneficially, a controller is fixedly connected to the upper end surface of the bottom plate. The controller controls the output power of the cold water pump, thereby controlling the size of the water mist sprayed out from the spray holes to adapt to oil fume waste gas with different flow rates. The water inlet pipe is a flexible pipe and can be rotated and deformed to a certain extent along with the rotation of the sealing cover. The sewage discharge pipe is a rigid pipe to ensure that the oily sewage can be smoothly discharged into the sedimentation tank.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] By providing a spray pipe, spray holes and a treatment tank, after high-pressure cold water is introduced into the spray pipe by a cold water pump, cold water mist is sprayed out through the spray holes. The cold water mist sprays towards the side wall of the condensation chamber, condenses the oil fume gas introduced from the air inlet pipe, and then flows downward for quick purification of the oil fume waste gas.

[0011] By providing a sewage discharge pipe and a sedimentation tank, after the condensed oil-water mixture is introduced into the sedimentation tank through the sewage discharge pipe, sedimentation and stratification are carried out, and finally the oil and water are separated.

A cold water pump 106 is fixedly connected to the rear side of the upper end surface of the bottom plate 100, and a water inlet pipe 105 is fixedly connected between the cold water pump 106 and the upper end surface of the bottom plate 100. The cold water pump 106 can pump cold water into the spray pipe 110 through the water inlet pipe 105. A sedimentation tank 109 is fixedly connected to the front side of the upper end surface of the bottom plate 100, and a sewage discharge pipe 108 is fixedly connected between the sedimentation tank 109 and the lower end of the treatment tank 102. The sewage discharge pipe 108 communicates the sedimentation tank 109 and the condensation chamber 112, so that the oil fume waste gas flowing through the condensation chamber 112 can be condensed by the cold water mist ejected from the spray holes 114 and then flow into the sedimentation tank 109 through the sewage discharge pipe 108 for sedimentation and stratification.

[0022] The treatment tank 102 is provided with a vacuum heat preservation chamber 111, and the vacuum heat preservation chamber 111 can heat-preserve the inside of the condensation chamber 112 to enhance the oil fume condensation effect inside the condensation chamber 112;

[0023] The side wall of the treatment tank 102 is fixedly connected with a support frame 101, and the lower end surface of the support frame 101 is fixedly connected with the upper end surface of the bottom plate 100;

[0024] An air inlet pipe 103 communicating with the air inlet chamber 115 is provided on the front side of the treatment tank 102, and the oil fume waste gas generated by food processing is introduced into the air inlet chamber 115 through the air inlet pipe 103 and then flows downward through the condensation chamber 112 for condensation;

[0025] A controller 107 is fixedly connected to the upper end surface of the bottom plate 100. The controller 107 controls the output power of the cold water pump 106, thereby controlling the size of the water mist ejected from the spray holes 114 to adapt to oil fume waste gas with different flow rates. The water inlet pipe 105 is a flexible pipe and can be rotated and deformed to a certain extent as the sealing cover rotates. The sewage discharge pipe 108 is a rigid pipe to ensure that the oily sewage can be smoothly discharged into the sedimentation tank 109.

[0026] Working principle:

[0027] First, start the cold water pump 106 through the controller 107. The cold water pump 106 pumps in low-temperature cold water, pressurizes it, then passes it through the water inlet pipe 105 into the spray pipe 110, and finally sprays out cold water mist from the spray holes 114 to fill the entire condensation chamber 112.

[0028] Then, the oil fume waste gas generated during processing enters the intake chamber 115 through the intake pipe 103, and then flows downward through the condensation chamber 112. When flowing through the condensation chamber 112, the high-temperature oil fume waste gas meets the low-temperature water mist and condenses into an oil-water mixture, which falls downward and passes through the sewage discharge pipe 108 into the sedimentation tank 109.

[0029] Finally, the oil-water mixture is left to stand and separate in the sedimentation tank 109. After pumping out the water on the upper layer, the oil stain can be separated and processed.
