The utility model discloses a high-temperature steam exhaust energy-saving system of an autoclave in the building material industry, which is used for recovering waste heat and energy-saving treatment of waste gas of high-temperature steam generated in the production process of the autoclave.
Referring to fig. 1, the present utility model includes: an autoclave 10, a condenser 20, a heat exchanger 30, a cooling tower 40 and a wastewater collection tank 50.
The autoclave 10 is used for discharging high-temperature steam containing dust, and the high-temperature steam is an energy-saving treatment object of the utility model. The condenser 20 is used for realizing the first-stage cooling of the autoclave 10, and has an air inlet end for inputting high-temperature steam, an air outlet end for outputting steam condensate (a product formed by condensing the high-temperature steam by the condenser 20), an air inlet end for inputting a cooling medium (the cooling medium can be cooling water or other cooling mediums, and is used for cooling the high-temperature steam and recovering waste heat of the high-temperature steam), and an air outlet end for outputting the cooling medium. The air outlet end of the autoclave 10 is connected to the air inlet end of the condenser 20, so that the high-temperature steam discharged from the autoclave 10 enters the condenser 20.

The air outlet end of the condenser 20 is connected to the first heat exchange channel of the heat exchanger 30, and the high-temperature steam cooled by the condenser 20 is converted into condensed water and enters the first heat exchange channel.
The cooling tower 40 is used for outputting cooling water for the system, and the cooling tower 40 is provided with a water inlet end, a first water outlet end 41 and a second water outlet end 42. The first heat exchange channel of the heat exchanger 30 is connected to the water inlet end of the cooling tower 40, so that condensed water after high-temperature steam conversion enters the cooling tower 40 again for circulation after further heat exchange of the heat exchanger 30; the first water outlet end 41 of the cooling tower 40 is connected to the water inlet end of the condenser 20, and provides cooling water for the condenser 20, so that the cooling water and high-temperature steam generate heat exchange inside the condenser 20; the second water outlet end 42 of the cooling tower 40 is connected to the second heat exchange channel of the heat exchanger 30, so that the condensed water after the high-temperature steam is converted exchanges heat with the cooling water, the temperature of the condensed water of the high-temperature steam is further reduced, and the cooling water further recovers the residual heat of the high-temperature steam.
