[0021] In the existing devices, the purpose of treating water is achieved by baking the water in the open container with gas to make the water evaporate gradually. However, this method has low efficiency and high operating cost, which is not conducive to popularization and implementation. Therefore, there are shortcomings. Therefore, the inventor provides a backflow liquid evaporation device after research, which can achieve good evaporation efficiency, high working efficiency and low cost of operation, which is conducive to popularization and implementation.

[0022] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0023] Please refer to Figure 1 The embodiment of the utility model provides a return liquid evaporation device, including a combustion chamber 100 and an evaporation chamber 200. The evaporation chamber 200 is used to evaporate the return liquid, and the combustion chamber 100 is used to accelerate the evaporation of the return liquid.

[0024] Please refer to Figure 2The combustion chamber 100 includes a combustion chamber 110 and an igniter 120. The combustion chamber 110 is hollow in design. The igniter 120 is fixedly connected in the combustion chamber 110. An air inlet 130 is reserved at the upper end of the igniter 120. The evaporation chamber 200 includes an evaporation chamber 210, an evaporation coil 220 and a return liquid spray member 230. The evaporation chamber 210 is fixedly connected to the upper side around the combustion chamber 110. The evaporation coil 220 is fixedly connected to the inside of the evaporation chamber 210, and the evaporation coil 220 is in close contact with the cavity wall of the combustion chamber 110. The return liquid spray member 230 is fixedly connected to both sides of the evaporation chamber 210, and the output end of the return liquid spray member 230 passes through the side wall of the evaporation chamber 210 and extends into the evaporation chamber 210. When in use, the natural gas is ignited through the igniter 120, thereby burning throughout the combustion chamber 110, and the heat is transferred to the evaporator coil 220, so that the evaporator coil 220 obtains a high temperature state, and the return liquid is sprayed on the evaporator coil 220 through the return liquid spray part 230, so that part of the return liquid is directly evaporated on the evaporator coil 220, and at the same time, part of the return liquid that has not yet evaporated falls into the evaporator chamber 210. Due to the heating effect of the combustion chamber 110 and the evaporator coil 220, the temperature inside the entire evaporator chamber 210 is very high, so that this part of the return liquid can also achieve the effect of rapid evaporation. In addition, the structure is simple as a whole and the cost is low, thereby solving the problems of slow evaporation efficiency, low work efficiency, high operating cost, and unfavorable promotion and implementation in the prior art.

[0025] Please refer to Figure 3 The return liquid spraying member 230 includes a liquid inlet 231, a water collecting tank 232, an output pipe 233 and a spray plate 234. The plurality of liquid inlets 231 are fixedly connected to one side of the water collecting tank 232. A water pump is arranged in the water collecting tank 232. One end of the output pipe 233 is fixedly connected to the water collecting tank 232. The other end of the output pipe 233 is connected to the spray plate 234. A mounting groove 211 is provided on the inner wall of the evaporation chamber 210. The spray plate 234 is fixedly connected to the mounting groove 211. The initially filtered return liquid enters the water collecting tank 232 through the liquid inlet 231 and is transported to the spray plate 234 through the water pump in the tank. The igniter 120 includes a blowout preventer installation port 121, an igniter body 122, and an ignition nozzle 123. The blowout preventer installation port 121 is fixedly connected to the side of the igniter body 122, and the ignition nozzle 123 is fixedly connected to the igniter body 122 in a dot matrix arrangement. Natural gas enters the igniter body 122 through the blowout preventer installation port 121, and is then ignited through the ignition nozzle 123, so that the entire combustion chamber 110 is filled with flames, which is convenient for heating.

[0026] Please refer to Figure 4 The spray plate 234 is provided with a spray nozzle 235, and the lowermost spray nozzle 235 has a certain inclination angle for aiming at the evaporation coil 220. The spray nozzle 235 sprays the return liquid on the evaporation coil 220.

[0027] Please refer to Figure 5 A cleaning port 140 is provided on one side of the combustion chamber 110. The cleaning port 140 is used to clean the residue left by the return liquid after evaporation. A manual escalator 150 is fixedly connected to the side of the combustion chamber 110. The manual escalator 150 is convenient for getting on and off the device. A movable wire mesh 160 is installed on the top of the combustion chamber 110. The movable wire mesh 160 is not in operation so that personnel can walk on the top of the device for inspection.

[0028] In summary, the working principle of the return liquid evaporation device of the embodiment of the utility model is as follows: when in use, natural gas enters the igniter body 122 through the blowout prevention tube installation port 121, and then is ignited through the ignition nozzle 123, so that it burns to the entire combustion chamber 110, and the heat is transferred to the evaporation coil 220, so that the evaporation coil 220 obtains a high temperature state, and the preliminarily filtered return liquid enters the water collection tank 232 through the liquid inlet 231, and is transported to the spray plate 234 by the water pump in the tank, and then sprayed through the spray nozzle 235. On the evaporator coil 220, part of the return liquid is directly evaporated on the evaporator coil 220, and at the same time, part of the return liquid that has not yet evaporated falls into the evaporator chamber 210. Due to the heating effect of the combustion chamber 110 and the evaporator coil 220, the temperature inside the entire evaporator chamber 210 is very high, so that this part of the return liquid can also achieve the effect of rapid evaporation. In addition, the structure is simple as a whole and low in cost, thereby solving the problems of slow evaporation efficiency, low work efficiency, high operating cost, and being unfavorable for promotion and implementation in the prior art.
