DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] As shown in Figures 1-4 The present application provides a technical solution:

[0026] The utility model provides a new heat exchanger for washing tower, including the box 1, is provided with temperature sensor 19 in the left side outside lower portion of box 1, is provided with circulating mechanism in the right side of box 1, and the circulating mechanism includes circulating pump 3, is provided with circulating pump 3 in the right side outside lower portion of box 1, and the water inlet end of circulating pump 3 is connected with box 1 through input pipe 4, and the water outlet end of circulating pump 3 is provided with output pipe 5, is provided with heat dissipation box 2 in the top middle portion of box 1, is provided with heat dissipation mechanism one in the inside of heat dissipation box 2, and heat dissipation mechanism one includes serpentine pipe 6, is provided with serpentine pipe 6 in the inside of heat dissipation box 2, is communicated with the water outlet pipe 7 in the right side upper end outside of box 1, is provided with switching valve 8 in the outside one end of water outlet pipe 7, and the water inlet pipe 9 is provided with connecting pipe 10 respectively in the other two ends of switching valve 8, and the one end of connecting pipe 10 is apart from switching valve 8 and is communicated with the right end of serpentine pipe 6, heat dissipation mechanism one also includes fan 11, is fixedly installed fan 11 in the top middle portion of heat dissipation box 2, is provided with air inlet 12 in the both ends of heat dissipation box 2, is fixedly installed dust screen 13 in the inside of air inlet 12, is provided with heat dissipation mechanism two in the inside upper portion of box 1, and heat dissipation mechanism two includes hollow straight pipe 14, is provided with a plurality of hollow straight pipes 14 in parallel in the inside upper end of box 1, and is provided with air filter 15 in the both ends of hollow straight pipe 14 and penetrates box 1 respectively;

[0027] In the embodiment, in different industrial production environments, the flow rate, temperature of waste gas and the operating load of the washing tower and other factors will change, and the cooperation of the heat dissipation mechanism one and the heat dissipation mechanism two can be flexibly adjusted according to the specific working conditions. When the flow rate of waste gas is large and the temperature is high, the heat dissipation intensity of the heat dissipation mechanism one and the heat dissipation mechanism two can be simultaneously increased, and when the flow rate of waste gas is small, the heat dissipation intensity can be appropriately reduced to save energy.

[0028] In some seasonal production factories, the production load and waste gas emission in different seasons will be different. In summer, the air temperature is high, and the temperature of waste gas is also relatively high. At this time, the synergistic effect of the heat dissipation mechanism one and the heat dissipation mechanism two can be fully utilized to strengthen heat dissipation. In winter, the temperature of waste gas is relatively low, and the heat dissipation intensity can be appropriately reduced to meet the production demand in different seasons.

[0029] As shown in Figure 3 and Figure 4 , a spraying mechanism is arranged between the heat dissipation mechanism two and the heat dissipation mechanism one, and the spraying mechanism includes an inner pipe 16. The inner pipe 16 is vertically arranged between the left side of the box 1 and the heat dissipation box 2. The top end of the inner pipe 16 is communicated with the left end of the serpentine pipe 6. The bottom end of the inner pipe 16 is fixedly installed with an atomizing nozzle 17. The two side upper ends of the atomizing nozzle 17 are fixedly connected with the box 1 through a hanger 18.

[0030] In this embodiment, the inner tube 16 of the spraying mechanism guides the refrigerant after heat dissipation through the serpentine pipe 6 to the atomizing nozzle 17, which atomizes the refrigerant into fine droplets. The droplets fully contact the rising hot gas flow or high-temperature liquid in the tank 1 during the falling process, and the droplets evaporate and absorb heat, which can quickly absorb a large amount of heat, thereby further reducing the temperature in the tank 1 and enhancing the heat dissipation effect of the entire heat exchanger.

[0031] In some high-temperature and high-pressure industrial production environments, the heat in the washing tower accumulates quickly, and only relying on the heat dissipation mechanism one and the heat dissipation mechanism two may not meet the heat dissipation demand. The atomized droplets of the spraying mechanism can quickly absorb heat, play a role in rapid cooling, effectively prevent the temperature in the washing tower from being too high, and ensure the normal operation of the system.

[0032] Working principle: when working, the circulating pump 3 is started, the water inlet end of the circulating pump 3 is communicated with the box body 1 through the input pipe 4, it extracts the refrigerant which needs to be heat exchanged from the box body 1, the circulating pump 3 provides power for the flow of the refrigerant, so that the refrigerant forms a cycle in the system, the extracted refrigerant is pressurized after the circulating pump 3, is transported to the condenser in the washing tower from the water outlet end of the circulating pump 3 through the output pipe 5, after completing heat exchange, flows back to the box body 1, and continuously circulates, so as to maintain the heat exchange process of the whole system, when the temperature of the refrigerant flowing back to the box body 1 is increased, the switching valve 8 acts, so that the refrigerant enters the serpentine pipe 6 in the heat sink box 2 through the connecting pipe 10, the serpentine pipe 6 has a large surface area, when the liquid flows in the serpentine pipe 6, heat is transferred to the surrounding environment through the pipe wall of the serpentine pipe 6, and preliminary heat dissipation is realized, at the same time, the fan 11 located at the middle of the top end of the heat sink box 2 is started, the fan 11 rotates to generate air flow, the air flow enters the inside of the heat sink box 2 from the air inlet 12 at one end of the heat sink box 2, passes through the serpentine pipe 6, and then flows out from the air inlet 12 at the other end, the forced convection can accelerate the flow speed of the air around the serpentine pipe 6, so that the heat exchange efficiency between the serpentine pipe 6 and the surrounding air is improved, and the heat dissipation effect is further enhanced, when the temperature of the liquid in the box body 1 is higher, heat is transferred to the hollow straight pipe 14, under the action of pressure difference or natural convection, external air enters the inside of the hollow straight pipe 14 through the air filter 15, the air filter 15 can filter out dust and impurities in the air, so that the heat dissipation effect is not affected when the dust and impurities enter the inside of the hollow straight pipe 14, after the air entering the inside of the hollow straight pipe 14 absorbs the heat transferred by the hollow straight pipe 14, the air flows out of the box body 1 from the air filter 15 at the other end, the heat of the liquid in the box body 1 is taken away through the heat conduction and convection, so that the liquid in the box body 1 is further heat dissipated, when the liquid in the serpentine pipe 6 is heat dissipated, part of the liquid flows downward through the inner pipe 16, and finally reaches the atomizing nozzle 17 fixedly installed at the bottom end of the inner pipe 16, the atomizing nozzle 17 atomizes the liquid into fine droplets, the droplets are sprayed downward under the action of gravity, the atomized droplets contact the hot gas flow or high-temperature liquid rising in the box body 1 in the falling process, the heat in the box body 1 is further absorbed through the evaporation heat absorption of the droplets, so that the heat dissipation effect of the whole heat exchanger is enhanced.
