DETAILED DESCRIPTION

[0027] Example 1:

[0028] Please refer to Figures 1-5The utility model provides a new type of setting machine oil fume waste gas purification device, including waste gas pipe 1, white equipment 2, spray filter integrated equipment 3, heat exchange equipment 4 and high voltage electrostatic tower 5, white equipment 2 includes the heat absorption pipe 24 and the heat release pipe 25 in the heat absorption pipe 24 upper part, is equipped with a plurality of superconductive heat pipe 26 between heat absorption pipe and heat release pipe, and the both ends of a plurality of superconductive heat pipe 26 are located heat absorption pipe 24 and heat release pipe 25 inside respectively, and one end of waste gas pipe 1 and heat absorption pipe 24 are communicated, when the waste gas enters the inside heat absorption pipe 24, the heat of waste gas will be absorbed by superconductive heat pipe 25, thereby reducing the temperature of waste gas, namely the oil fume particles in waste gas will condense and separate out, thereby realizing the effect of removing part oil fume particles, in addition, when the temperature of waste gas reduces, can reduce the flue gas temperature required by subsequent heat exchange equipment to reduce, reach the effect of energy saving.

[0029] The other end of heat absorption pipe 24 is connected with spray filter integrated equipment 3, and the spray filter integrated equipment 3 includes a spray tower 6, a spray pipe 7, a filter screen 8 and a cleaning device 9. The filter screen 8 is arranged in the spray tower 6, and the filter screen 8 is in an inverted conical shape. The filter screen 8 divides the spray tower 6 into an air inlet cavity 10 and an air outlet cavity 11. The air inlet cavity 10 is located at the bottom of the air outlet cavity 11. The spray pipe 7 is arranged in the air outlet cavity 11, and the output end of the spray pipe 7 corresponds to the filter screen 8. The cleaning device 9 is arranged in the air inlet cavity 10, and the cleaning device 9 includes a motor 12, a scraper 13 and a support 14. The motor 12 is installed in the air inlet cavity 10, and a protective shell 20 is installed on the outside of the motor 12. The protective shell 20 is used to protect the motor 12 and prolong the service life of the motor 12. The support 14 is installed at the output end of the motor 12, and the scraper 13 is installed on the support 14. The scraper 13 and the filter screen 8 are close to each other on the side close to the air inlet cavity 10.

[0030] The waste gas passing through the heat absorption pipe 24 enters the spray tower 6, and the spray pipe 7 sprays liquid. When the liquid falls on the filter screen 8, a water film is formed. Since the waste gas moves upward, the waste gas passes through the filter screen 8, and the water film on the filter screen 8 cools the waste gas, so that the oil fume particles in the waste gas are separated out and adhere to the filter screen 8. This avoids the oil fume particles in the subsequent flue gas from adhering to the subsequent heat exchange equipment 4, ensures the subsequent heat exchange effect, and drives the support 14 to rotate through the motor 12. The scraper 13 is driven to rotate through the rotating support 14, and the scraper 13 cleans the filter screen 8. In addition, the bottom of the spray tower 6 is connected to an oil-water separation tank 22, and a water pump is connected to the output end of the oil-water separation tank 22. The water pump is communicated with the spray pipe 7. The oil fume particles and water are separated through the oil-water separation tank 22, and the water is sprayed out through the spray pipe 7 again through the water pump. This realizes the secondary use of water resources. In addition, the water film can also remove various pollutants in the flue gas, including particulate matter, acidic gases (such as SO2), basic gases and organic matter.

[0031] The gas outlet end of the spray tower 6 is connected with the heat exchange device 4, which can reduce the temperature of the waste gas. The heat exchange device 4 is a plate heat exchanger, and the heat exchange device 4 is connected with a cooling tower 21. The cooling tower 21 is used to cool the medium for heating the flue gas of the heat exchange device 4, so as to circulate and cool the flue gas, thereby ensuring the cooling efficiency. The output end of the heat exchange device 4 is connected with the high-voltage electrostatic tower 5. Most of the dust in the waste gas is removed through the high-voltage electrostatic tower 5.

[0032] The output end of the high-voltage electrostatic tower 5 is connected with a fiber filter device 23. The fiber filter device 23 includes a filter box 15 and a plurality of dust collecting bags 16. The filter box 15 is internally provided with a sealing frame 17. The plurality of dust collecting bags 16 pass through the sealing frame 17 and are connected with the sealing frame 17. The filter box 15, the dust collecting bags 16 and the sealing frame 17 cooperate to filter the flue gas through the dust collecting bags 16, so as to separate the dust and gas in the flue gas. The output end of the fiber filter device 23 is connected to one end of a heat releasing pipe 25. The superconducting heat pipe 26 in the heat absorbing pipe 24 absorbs the temperature of the waste gas. The superconducting heat pipe 26 transmits the temperature to the inside of the heat releasing pipe 25, so as to heat the waste gas in the heat releasing pipe 25, thereby realizing the removal of white smoke. One end of the heat releasing pipe is connected with a chimney 19.

[0033] Working principle:

[0034] In use, the waste gas pipe 1 is used to guide the external waste gas into the inside of the heat absorbing pipe 24. The superconducting heat pipe 26 absorbs the temperature of the flue gas, reduces the temperature, and precipitates part of the oil smoke particles in the waste gas. The waste gas passing through the heat absorbing pipe 24 enters the inside of the spray tower 6.

[0035] The spray pipe 7 sprays liquid. When the liquid falls on the filter screen 8, a water film is formed. Since the waste gas moves upward, the waste gas passes through the filter screen 8. The water film on the filter screen 8 cools the waste gas, so that the oil smoke particles in the waste gas are precipitated. The oil smoke particles are attached to the filter screen 8, so as to avoid the oil smoke particles in the subsequent flue gas from being attached to the subsequent heat exchange device 4, thereby ensuring the subsequent heat exchange effect. Meanwhile, the water film also removes various pollutants in the flue gas, including particulate matter, acidic gas (such as SO2), basic gas and organic matter. The motor 12 drives the support 14 to rotate, and the scraper 13 is driven to rotate through the rotating support 14. The scraper 13 passes through the filter screen 8 to achieve a cleaning effect. In addition, the bottom of the spray tower 6 is connected to an oil-water separation tank 22. The output end of the oil-water separation tank 22 is connected with a water pump. The water pump is connected with the spray pipe 7. The oil-water separation tank 22 can separate the mixed oil smoke particles and water. The water pump sprays the water through the spray pipe 7 again, thereby realizing the secondary use of water resources.

[0036] The exhaust gas passing through the spray tower 6 will enter the heat exchange device 4, which will reduce the temperature of the exhaust gas. The heat conducting medium of the heat exchange device 4 is connected with the cooling tower 21, and the heat conducting medium of the heat exchange device 4 is cooled through the cooling tower 21. After passing through the high-voltage electrostatic tower 5, most of the dust in the exhaust gas is removed. The exhaust gas will enter the fiber filter device 23. The filter box 15, the dust collecting bag 16 and the sealing frame 17 cooperate to filter the flue gas through the dust collecting bag 16, so as to separate the dust and gas in the flue gas. The heat releasing pipe 25 can transfer the heat in the heat absorbing pipe 24 to the exhaust gas through the superconducting heat pipe 26, so as to increase the temperature of the exhaust gas, thereby realizing the effect of removing white smoke. The chimney 19 is used for discharging the flue gas.
