Description
Technical field
The utility model relates to the boiler that a kind of vertical shaft type reclaims high temperature powdery solid material waste heat, and recyclable high temperature powdery solid material waste heat is output as saturated vapor.
Background technology
The waste heat boiler of current recovery high-temperature solid material waste heat is common following several pattern: the waste heat boiler that 1, reclaims the big fast regular shape solid material waste heat of high temperature adopts tunnel type more, reclaims the solid material waste heat by the radiation heat transfer mode; 2, the waste heat boiler that reclaims the big fast loose solid material waste heat of high temperature adopts forced convertion mode heated gaseous intermediate medium more, reclaims the heat of gaseous state intermediate medium then by conventional flue type residual heat boiler; 3, the waste heat boiler that reclaims the loose solid material waste heat of high temperature granule adopts fluidisation (boiling) mode heated gaseous intermediate medium more, reclaims the heat of gaseous state intermediate medium then by conventional flue type residual heat boiler.
More than three kinds of waste heat boilers all need use high temperature air to make heat transferring medium, one time heat loss is big, and the dust contained flue gas of sending is big, must can reach environmental requirement through dust suppression, yet take dust suppression will cause the waste of power and water.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides the boiler of the recyclable high temperature powdery of a kind of vertical shaft type solid material waste heat, and it does not have ash-laden gas to discharge, and can not cause environmental disruption, does not have the waste of power and water yet.
The technical scheme that the utility model adopted is: it comprises vertical shaft, evaporation tube row, communicating pipe, drum, down-comer and steam guiding tube at the bottom of the band inversed taper platform shape of bottom, described vertical shaft is made of refractory material and insulation material, top is provided with charging aperture, and the bottom is provided with discharge gate; Described evaporation tube row is made up of left and right collection case and Duo Gen evaporation tube, evaporation tube with about collection case sealing communicate, evaporation tube row places vertical shaft, series connection between each evaporation tube row, the right side collection case that is next group evaporation tube row communicates by the communicating pipe sealing with adjacent last one group of evaporation tube row's left side collection case, and the right side collection case of going up one group of evaporation tube row in the vertical shaft most communicates with the drum sealing by steam guiding tube; Described drum above vertical shaft, drum by in down-comer and the vertical shaft next group evaporation tube row's left side collection case sealing communicate.
Described down-comer is serially connected with water circulating pump, and described drum is in the optional position of vertical shaft above-below direction.
The utility model is to send high-temperature dust or granule solid material to the boiler inlet, and it is directly contacted with the heat conduction evaporation tube row of boiler, adopts the transmission of heat by contact mode, the heat exchanger effectiveness height.Because high-temperature material flow velocity in boiler is very slow, so can not produce than galling, do not have flue dust yet and discharge evaporation tube row, therefore do not need to adopt any dust suppression.With compare as the waste heat boiler of heat exchange medium with air, have the advantage of saving the electricity charge and water rate.
