Step 1, preparation
Push driving handle(1), Combined type dehumidifying device in subway station is moved to the big construction operation of water capacity in subway station Region, junction box(13)It is connected with subway station interior power;
Step 2, freeze drying
Start semiconductor cooler(9)With electrothermal resistance silk screen(18), semiconductor cooler(9)Start to water tank(21)Interior water into Row refrigeration, water circulating pump(8)By water tank(21)Interior chilled water is sent into annular copper pipe(3)In, make annular copper pipe(3)Outer surface temperature Degree then starts wind turbine less than air dew point temperature in subway station(12)And electrostatic precipitator(2), draught fan impeller rotation is to subway Air generates air draught effect in standing, and gas passes through electrostatic precipitator(2)Into blast pipe(10), into blast pipe(10)Interior height Humid air encounters evenly arranged annular copper pipe(3)It condenses, condenses the moisture of precipitation under the effect of gravity along annular copper Pipe(3)It slides to variable diameter guide flow device(4), then pass through diversion pipe(5)Flow into header tank(6);
Step 3, heating dehumidifying
Highly humid air is by annular copper pipe(3)Become low temperature and low humidity air after condensation and passes through wind turbine(12)It blows into wind turbine Pipe(22)Section, low temperature and low humidity air is in ajutage(22)Pass through electrothermal resistance silk screen at section(18)High temperature low-humidity air is heated to form to send Entering in subway station, high temperature low-humidity air carries out hot and humid area with the highly humid air in subway station, and air themperature increases in subway station, Wall surface condensed formation flow by thermal evaporation, but without steam condensation be precipitated;
Step 4, ventilation drying
In dehumidification process, wind turbine(12)Convection current is formed with the exhaust blower at the air port of subway station both ends, the damp-heat air that gives up is from subway It stands and is discharged at air draft.
10. the application of Combined type dehumidifying device in a kind of subway station, it is characterised in that:Combined type dehumidifying device in the subway station For the dehumidifying of work zone in subway station, in application, in subway station Combined type dehumidifying device wind turbine(12)With subway station Exhaust blower at the air port of both ends forms convection current.
