Dry quenching furnace system cooling apparatus

The invention discloses a dry quenching furnace system cooling apparatus. The apparatus comprises a shell, a gas inlet dry tube, a heat exchange tube and a sand removal device, the lower portion of the shell is provided with a sand outlet and a sewage outlet, the heat exchange tube has a water inlet and a water outlet, two sides of the dry quenching furnace system cooling apparatus are provided with a gas inlet and a gas outlet, the sand removal device is arranged at the gas inlet, the gas inlet dry tube introduces a compressed inert gas from the outside, the open pores of the gas inlet dry tube are vertically provided with a plurality of branch tubes, the branch tubes are respectively provided with equidistant transverse gas blowing tubes paralleling to the heat exchange tube, the other end of the transverse gas blowing tube is welded to the shell, and the heat exchange tube is composed of in-line arranged or staggered straight tubes and a bent tube connecting two straight tubes. The apparatus allows ash blowing cleaning to be carried out without shutdown, so manpower is reduced, economy loss caused by cleaning shutdown is eliminated, and mechanical wearing caused by dismounting of the heat exchange tube is avoided.
