[0022] As shown in Figure 2 and Figure 3As shown, the demisting assembly comprises a partition 8 and a mist catching net 11 fixedly installed inside the demisting box 5, for dividing the demisting box 5 into a wet steam chamber 10 and a dry gas chamber 12, the bottom of the annular plate 6 and located in the wet steam chamber 10 is communicated with the spray head 7, the inner wall of the wet steam chamber 10 and located at the bottom of the annular plate 6 is fixedly connected with a plurality of condensation plates 9, one side of the bottom of the wet steam chamber 10 is communicated with the first connecting pipe 16, the inner wall of the dry gas chamber 12 is inserted with a plurality of activated carbon adsorption nets 13, one side of the dry gas chamber 12 is fixedly connected with the fan 14 and the air inlet end of the fan 14 is communicated with the dry gas chamber 12.

[0023] Specifically, the partition 8 and the mist catching net 11 effectively divide the inner cavity of the demisting box 5 into the wet steam chamber 10 and the dry gas chamber 12, realizing dry and wet separation, which helps to separate water molecules in the water mist from the air; the spray head 7 is designed to form a ring-shaped water curtain to capture water molecules in the water mist, increase its weight, and at the same time promote the conversion of mist to water droplets through the condensation plate 9, and fall together on the bottom of the inner cavity of the wet steam chamber 10; through the cooperation of the first connecting pipe 16 and the water pump 15, the water is circulated to the annular plate 6 and the heat exchanger body 1; the mist catching net 11 is used to block the wet steam chamber 10 and convert the attached mist on its surface into water droplets, so that it slides down to the bottom of the inner cavity of the wet steam chamber 10; the design of the activated carbon adsorption net 13 is used to adsorb and filter the residual water vapor entering the dry gas chamber 12 again, to ensure that the discharged air is clean.

[0024] As shown in Figure 2 and Figure 3 , a plurality of condensation holes are formed on each set of condensation plates 9, and one side of each condensation plate 9 is tightly attached to the mist catching net 11.

[0025] Among them, the design of the condensation plate 9 aims to adsorb water molecules in the mist and transfer them to the bottom of the wet steam chamber 10 through the condensation holes, and then deliver them to the water pump 15 through the first connecting pipe 16 for water recycling; the condensation plate 9 is tightly attached to the mist catching net 11, which helps to block the water mist on the top layer and separate the water molecules in the water mist from the air through the mist catching net 11, realizing effective isolation effect.
