More Information
Summary:The utility model provides a weary steam removes dust and water recovery system for brown coal are dry has set up nitrogen gas source, vapour source, weary steam by -pass and two -stage difference in temperature heat exchanger group in the system. Medium temperature in the one -level dew point heat exchanger makes weary steam drop the temperature of about 75 DEG C of dew points to. Medium temperature in the second grade condensation point heat exchanger is the temperature below the weary steam condensation point. Inside the high temperature high pressure nitrogen gas blowback dust remover, steam passes through heating coil and heats the dust remover, and under nitrogen gas and steam effect, the dust remover keeps avoiding the temperature of dew point, has avoided the trouble that the dust remover sack was lived by the dust paste under the dew point temperature. Nitrogen gas reduces the oxygen content, makes dust remover operation safety. Before the oxygen content of dust remover and temperature missed the req
