[0027] The constant temperature water tank 19 is provided with a water float valve 5 for controlling water inlet and water level, and maintaining the height of the liquid level 2 in the water tank. Preferably, a shield 6 is provided above the water float valve 5, and the shield 6 is fixedly mounted on the inner wall of the box body 1, and the shield 6 is used to prevent the water float valve 5 from being impacted by water flow and air flow.
[0028] The condensate cooling device 15 is provided with an overflow port 10 for controlling the upper limit of the water level of the constant temperature water tank 19 .
[0029] The water pump 8 of the spray cooling device 16 provides high-pressure water to the spray head 9 through the water pipeline 7, and solidifies the tiny particles below PM10 such as particulate matter, oil smoke, non-methane total hydrocarbons in the flue gas after the first condensation cooling in the condensed water.
[0030] Furthermore, the water pump 8 is a submersible pump, and the water pump 8 is arranged in a constant temperature water tank 19 .

The gas outlet 13 can be connected to the delivery pipeline through the provided connection flange as needed to discharge clean air.
[0036] Example:
[0037] The utility model discloses a vertical water-washing cold-treatment oil fume deodorizing device, which is installed at the end of a pipeline of a kitchen oil fume treatment and exhaust system, and is used for treating the residual smell and oil droplets in the fume after conventional kitchen oil fume treatment, so as to obtain pollution-free clean gas.
[0038] like Figure 1 As shown, the housing 1 of the vertical water-washing cold-treatment oil fume deodorization device is functionally divided into two parts, the lower part of the housing 1, a condensing water cooling device 15 is arranged at the lower part of the housing 1, and the upper part of the housing 1 includes a flue gas inlet 12, a gas outlet 13 and a spray cooling device 16 arranged side by side at the top; below the flue gas inlet 12 is the liquid level of the constant temperature water tank 19 of the condensing water cooling device 15; the gas outlet 13 is installed with three layers of water-draining nets 14. The flue gas entering the housing 1 through the flue gas inlet 12 is sequentially cooled and condensed by the condensing water cooling device 15, washed with water by the spray cooling device 16 and the water-draining net 14 at the gas outlet 13 to obtain clean and odorless gas, which is discharged through the gas outlet 13.
[0039] The refrigeration unit 3 of the condensed water cooling device 15 is arranged in the space isolated from the lower part of the box body 1. The condenser 4 of the refrigeration unit 3 is arranged in a constant temperature water tank 19, and the water temperature in the constant temperature water tank 19 is maintained at 0-5°C by refrigeration; a heat dissipation window 18 and an inspection door are arranged on the side wall of the box body 1 where the refrigeration unit 3 is located. The refrigeration unit 3 sets the operation mode and parameters through the control panel 17, and always keeps the water in the water tank at a constant temperature. When the flue gas enters the box body 1 downward from the flue gas inlet 12, the liquid surface 2 of the constant temperature water tank 19 with a temperature of 0-5°C cools the flue gas.
[0040] The constant temperature water tank 19 is provided with a water float valve 5 for controlling water inlet and water level, and maintaining the height of the liquid level 2 in the water tank; the water float valve 5 is located below the gas outlet 13. A protective cover 6 is provided above the water float valve 5, and the protective cover 6 is fixedly mounted on the side wall of the box body 1, and the protective cover 6 is used to prevent the water float valve 5 from being impacted by water flow and air flow.
[0041] The condensate cooling device 15 is provided with an overflow port 10 for controlling the upper limit of the water level of the constant temperature water tank 19 .
[0042] The spray cooling device 16 includes a water pump 8, a water pipeline 7, and a spray head 9, and the spray head 9 is installed on the water pipeline 7. The water pump 8 is a submersible pump, and the water pump 8 is arranged below the water float valve 5 in the constant temperature water tank 19; the spray water comes from the constant temperature water tank 19, and the water temperature is 0-5°C. The water pump 8 provides high-pressure water to the spray head 9 through the water pipeline 7.

[0046] The control panel 17 of the oil fume deodorizing device is arranged on the side surface outside the box body 1 .
[0047] A valve is installed on the water supply pipe connected to the water pump 8.
[0048] The working principle of the oil fume deodorizing device of the utility model is:
[0049] First, the high-temperature flue gas enters the vertical water-washing cold-treatment fume deodorization device, and contacts the water surface of the constant temperature water tank with a temperature of 0 to 5°C for cooling. After reflection, the flue gas with residual temperature is sprayed with condensed water to further dilute and clean the fume, thereby achieving the purpose of flue gas cooling.
[0050] Then, the condensed water condenses the tiny particles below PM10, such as particulate matter, oil smoke, and non-methane total hydrocarbons in the oil smoke, into large particles again, and uses the fluidity of the condensed water spray to clean them, and further achieves the purpose of oil smoke purification through the grease cleaning decomposition agent in the condensed water;
[0051] In the purification process of the kitchen exhaust system, such as: electrostatic purification of oil fume, low-temperature plasma purification of oil fume, or UV purification and deodorization, ozone will be generated. The utility model utilizes the physical property of ozone that it can be dissolved in water and deodorize. Under the action of the wind pressure of the kitchen exhaust system, the ozone is pressed into the condensate water tank, and meets the oil fume, particulate matter, non-methane total hydrocarbons and other media in the condensate water containing grease cleaning decomposition agent again, so that the ozone no longer diffuses into the air, thereby achieving the purpose of purifying the smoke and removing the taste in the box.
[0052] The utility model has the characteristics of cooling, removing particulate matter, oil smoke, non-methane total hydrocarbons, and removing odors. According to the installation conditions, it can be installed at the outdoor end of the exhaust system or on the indoor self-circulating modular oil smoke treatment device. In particular, the indoor installation effect is better. There is no need to install outdoor pipes and winter maintenance. It can continuously circulate and cool the high temperature environment of the kitchen. After condensation water cooling, spray cooling and cleaning, and the gas outlet drainage net, the clean and odorless gas is discharged into the environment, making the environment more comfortable and providing an excellent working environment for the kitchen.
[0053] It should be noted that the above-mentioned embodiments are examples rather than limitations of the present invention, and those skilled in the art will be able to design many alternative embodiments without departing from the scope of the claims of this patent.
