On be provided with gas discharge outlet.
Further, described spray thrower includes several spray heads.
The utility model has the advantages and positive effects that:
1st, the exhaust opening on boiler body passes through entering of the exhaust gases passes in u shape structure in gas pipeline and heat-exchanging water tank
Gas port connects, and substantially prolongs the time of staying in exhaust gases passes for the high-temperature flue gas, thus effectively transferring heat to heat exchange
Water in water tank, the delivery port of heat-exchanging water tank is connected with ring-shaped water jacket by aqueduct, so that having uniform temperature
Water circulation enters ring-shaped water jacket and is heated, is effectively utilized the heat energy of high-temperature flue gas, has saved the energy；
2nd, the flue gas after heat-exchanging water tank cooling sequentially passes through cyclone separator by the most of dust in flue gas and particle
Remove, subsequently enter sack cleaner, further the micronic dust in flue gas is removed, finally enter absorption chamber, by shower water or
Other absorbing liquids of person absorb to the pernicious gas in flue gas, and the waste liquid entrance waste collection pond absorbing gained is easy to subsequently locate
Reason, finally by the fume emission after processing, greatly reduces the pollution to environment.
