[0034] The present application provides a dehumidification system for a kitchen waste fermentation tank, as shown in Figures 1 to 5

[0035] Embodiment one:

[0036] ​A kind of dehumidification system for kitchen garbage fermentation tank, including base 1, ventilation system and dehumidification heat pump unit are installed on base 1, ventilation system can extract the gas of high temperature and high humidity (the working condition required by fermentation process) of fermentation tank, the high temperature and high humidity gas extracted is changed into dry high temperature gas and reenters the inside of fermentation tank under the action of dehumidification heat pump unit, to realize the dehumidification of the inside of fermentation tank.

[0037] Ventilation system includes box 2, box 2 is installed on base 1, both ends of box 2 are respectively provided with air inlet pipe 3 and air outlet pipe 4, air inlet pipe 3 is communicated with the fermentation tank of outside by ventilator, air inlet pipe 3 is connected with the fermentation tank, and dust screen is fixedly connected on the inner side wall of fermentation tank, the position of air inlet pipe 3, the setting of dust screen can avoid the impurities in the inside of fermentation tank to enter the inside of air inlet pipe 3 and affect the flow of air, air outlet pipe 4 is also communicated with the fermentation tank of outside, under the action of ventilator, the gas in the inside of fermentation tank will enter the inside of box 2 through air inlet pipe 3, and then enter the inside of fermentation tank through air outlet pipe 4, to form circulation.

[0038] Dehumidification heat pump unit includes compressor set 5, condensing dehumidifier 6 and back temperature evaporator 7, compressor set 5 is installed on base 1, condensing dehumidifier 6 is installed in the inside of box 2 and close to one end of air inlet pipe 3, back temperature evaporator 7 is installed in the inside of box 2 and close to one end of air outlet pipe 4, condensing dehumidifier 6 and back temperature evaporator 7 are connected with each other, compressor set 5 can reduce the temperature of condensing dehumidifier 6 end when working, and the heat generated can be transmitted to back temperature evaporator 7, so that the temperature around condensing dehumidifier 6 can be reduced, and the temperature around back temperature evaporator 7 can be increased (the working principle of compressor set 5 is prior art, and it has been widely applied, so the utility model is not described in detail).

[0039] After the high temperature and high humidity gas in the inside of fermentation tank enters the inside of box 2, it will first contact condensing dehumidifier 6, because the temperature around condensing dehumidifier 6 is low, so the high temperature and high humidity gas will first be condensed into low humidity and low temperature gas, and then contact back temperature evaporator 7, which is heated by back temperature evaporator 7 (back temperature evaporator 7 can heat the air to above 60 DEG C), so as to become high temperature dry gas, and finally return to the inside of fermentation tank, in the above process, the gas in the inside of fermentation tank is dehumidified, and the cooling of the inside of fermentation tank is reduced, so that the energy consumption of fermentation tank is greatly reduced in the dehumidification process.

[0040] In order to make the condensing dehumidifier 6 and the temperature recovery evaporator 7 fully contact with the air in the process of air flow, make the condensing dehumidifier 6 better condense, and make the temperature recovery evaporator 7 better heat, the plurality of finned tube dehumidifiers in the condensing dehumidifier 6 and the plurality of finned tube temperature recovery evaporators in the temperature recovery evaporator 7 are arranged in a staggered distribution state, so that the condensing dehumidifier 6 and the temperature recovery evaporator 7 can fully contact with the air in the process of air flow.

The flow uniformizing plate 12 arranged between the air inlet pipe 3 and the condensing dehumidifier 6 can make the high-temperature and high-humidity gas fully contact with the condensing dehumidifier 6, thereby improving the condensing efficiency. The flow uniformizing plate 12 arranged between the condensing dehumidifier 6 and the temperature recovery evaporator 7 can make the condensed gas fully contact with the temperature recovery evaporator 7, thereby improving the heating efficiency.

[0042] The water pan 8 is arranged on the lower side wall of the inside of the box body 2. The water produced after the high-temperature and high-humidity gas is condensed will fall on the lower side wall of the inside of the box body 2, and then flow into the inside of the water pan 8. The water pan 8 is provided with the drain pipe 9. The drain pipe 9 is in the shape of “U”. One end of the open end of the drain pipe 9 is the water inlet end which is communicated with the water pan 8, and the other end is the water outlet end which is bent to the horizontal direction and communicated with the outside drain pipe. The bending part of the drain pipe 9 will store a certain amount of water, which plays a sealing role, so that the gas in the box body 2 will not leak. When the liquid level in the communication end of the drain pipe 9 and the water pan 8 is higher than the bending end of the drain pipe 9, the water in the drain pipe 9 will be smoothly discharged through the discharge end of the drain pipe 9.

[0043] The arrangement of the drain pipe 9 can make the air in the fermentation tank not discharge waste gas in the fermentation process, so that the air in the fermentation tank realizes full closed loop operation in the fermentation process, and does not pollute the environment.

[0045] Further, in order to improve the utilization efficiency of energy, improve the energy saving effect, the base 1 is further provided with a heat recovery system, the heat recovery system comprises a heat exchanger 10 and a circulating pipe 11, the heat exchanger 10 is installed on the base 1, the circulating pipe 11 is installed in the compressor set 5, the circulating pipe 11 is communicated with the heat exchanger 10 through a circulating water pump, under the action of the circulating water pump, water flows in the circulating pipe 11 and the heat exchanger 10, the heat generated during the operation of the compressor set and part of the heat energy released during the dehumidification and condensation process are transmitted to the heat exchanger 10, the heat exchanger 10 is provided with a cold water inlet pipe and a hot water outlet pipe, the cold water inlet pipe and the hot water inlet pipe are communicated through a copper pipe, when the water outside flows in the copper pipe, the water flowing from the circulating pipe 11 to the heat exchanger 10 heats the water, so that the heat exchanger 10 can heat the water outside, and the heated hot water is used in the kitchen and other areas needing hot water.
