Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification, in particular to an oil fume purification treatment device for grain and oil processing production. Background Art

[0002] A large amount of oil fume waste gas will be emitted during the processing of grain and oil. In addition to water vapor, oil mist and fine particles, the oil fume also contains volatile substances and odorous gases. These gaseous substances are not friendly to the environment and human body. Large-scale emissions are a great hazard to both the human body and the environment.

[0003] The existing fume purification treatment devices for grain and oil processing have some drawbacks. First, they cannot intercept and filter the large particles of dust generated by the processing, which easily leads to blockage inside the device. They are also not easy to disassemble and clean, affecting the use effect. Secondly, the purification steps are single and the purification effect is poor. Utility Model Content

[0006] Preferably, a soap water bin is provided at the lower portion of the fan 1, and a drying bin is provided at the upper portion of the soap water bin on the side of the fan 1.

[0007] Preferably, a smoke guide pipe is connected between the soap water tank and the fan 1, and a smoke outlet tray is connected to the lower end of the smoke guide pipe.

[0008] Preferably, a connecting pipe is connected to the front of the drying bin, and the lower end of the connecting pipe is fixedly connected to the upper end of the soap water bin.

[0009] Preferably, a decomposition bin is provided at the upper end of the side of the soap water bin, and an activated carbon bin is provided at the lower part of the decomposition bin.

[0010] Preferably, a conduit is connected between the upper end of the side of the decomposition chamber and the drying chamber, and ultraviolet UV lamp tubes are provided at both ends inside the decomposition chamber.

[0011] Preferably, a second fan is provided outside the activated carbon bin, and the upper end of the second fan is fixedly connected to the lower end of the side of the decomposition bin.

[0012] Preferably, an air supply pipe is connected between the lower ends of the lower end blower 2 at the side of the activated carbon bin, and an air outlet pipe is connected to the front of the activated carbon bin.

[0013] Compared with the prior art, the utility model has the following beneficial effects: it is easy to prevent dust from entering the device and causing blockage, and has a good purification effect;

[0014] The handle can be pulled outward to move the pull rod outward and compress the spring, thereby driving the push block to move and make way for the insert block. The dust filter layer can then be attached to the side of the smoke hood so that the insert block is inserted into the groove on the edge of the smoke hood. The handle is then released and the push block is reset through the pull rod under the push of the spring so that the push block is inserted into the insert block. In this way, the position of the dust filter layer is fixed on the smoke hood, which can intercept and filter large particles of dust generated during processing, and easily prevent dust from entering the device and causing blockage.

[0015] (2) Under the suction effect of fan 1, an airflow is formed in front of the smoke hood. The airflow drives the oil smoke through the smoke guide pipe and enters the soap water tank. Since there are multiple smoke outlets evenly distributed on the smoke outlet plate, the smoke can fully contact with the liquid in the soap water tank, which is conducive to the initial adsorption and precipitation of particulate matter in the oil smoke. Under the action of fan 2, the gas is introduced into the activated carbon tank through the gas pipe. The activated carbon in the activated carbon tank further adsorbs the gas, which is conducive to improving the purification effect. The treated gas is discharged from the outlet pipe with good purification effect. BRIEF DESCRIPTION OF THE DRAWINGS
