Abstract

The utility model relates to an ash hopper of a dust remover, which adopts steam as a heat source and aluminum powder as a heat conducting medium, and is heated by a coil pipe A snakelike metal coil pipe is arranged in a jacket between the outer side of an ash hopper wall and a thermal insulating layer; and the aluminum powder with high thermal conduction is filled in the space of the jacket. Thesteam heat in the coil pipe is unilaterally transferred in a thermal conduction manner through a pipe wall, an aluminum powder layer and the ash hopper wall so as to uniformly and quickly heat ash. Steam is finally coagulated into water and discharged.In the utility model, the aluminum powder with excellent thermal conduction replaces the prior air layer, so that the defect of slow heating of thetraditional coil pipe heating ash hopper is overcome. The utility model has the advantages of simple structure, good heating effect and no maintenance.

Description

The steam-heated dust collector ash hopper of heat-conducting type

Technical field

The utility model relates to a kind of dust collector ash hopper, especially the steam-heated dust collector ash hopper of heat-conducting type.

Technical background

The ash bucket of dust exhaustor is the grey ash discharging gear of a kind of collection.In order to prevent that ash from becoming the tide caking, keep ash discharge smooth and easy, need heat ash bucket, the temperature that makes grey headwall is more than 150 ℃.Present ash bucket SMD electro heat, the forms of outer insulation of adopting more.Every large-scale dust exhaustor electrical heating power reaches more than 200 kilowatt, and the operation consumption of current is huge, and electrical heating elements is fragile, maintenance difficult.Because steam is a lot of in the power plant, for electro heat, can save the energy about 80% with vapour, therefore once there were some power plant steam heating coil to be installed in the grey headwall outside, change electro heat into steam heating.But coil pipe can't be close to grey headwall, can only lean on the heat conduction and the free convection of air in the coil pipe interlayer that grey headwall is heated, and heats is very poor, so once adopted steam-heated power plant all to make electro heat again into.Therefore, dust collector ash hopper does not have reliable and energy-conservation heating way so far.

Summary of the invention

The electro heat energy consumption that has dust collector ash hopper now is big, heater element is fragile in order to overcome, and the problem of steam coils heats difference, the utility model provides a kind of steam-heated heat-conducting type novel deduster ash bucket that is applicable to.This dust collector ash hopper with steam be the heating thermal source, with metal powder (aluminium powder) augmentation of heat transfer, have energy-conservation, heats good and the advantage of freedom from repairs.

The technical solution of the utility model is: in the outside of dust collector ash hopper wall, install and fix the heat dissipation metal coil pipe.With insulation shell coil pipe is enclosed in the chuck, and in chuck, fills aluminium powder.Steam enters from the suitable for reading of coil pipe, be condensed into condensate water after, discharge through vapor and water separator from the coil pipe end opening, heat is conducted to grey headwall by coil pipe and aluminium powder packed layer.Aluminium powder is high conduction material, so steam coils is very fast and even to the heating of grey headwall, the temperature difference of steam and grey headwall is minimum.Owing to adopt steam heating, so compare energy-conservation 75-80% with present widely used electro heat.Compare with traditional steam coils heating, heats is much better.Chuck is interior without any consumable accessory simultaneously, and ash bucket does not need repairing.

The beneficial effects of the utility model are: heats is good, energy-conservation, manufacturing is simple, freedom from repairs.

The specific embodiment

In Fig. 1 Fig. 2, metal coil pipe (2) is fixed on outside the four sides of dust collector ash hopper (1) wall, use insulation shell (5) that coil pipe is enclosed in the chuck again, and fill chuck with aluminium powder (4).Steam is from suitable for reading the entering of coil pipe (2), and the mode of heat by heat conduction passed to grey headwall, is condensed into condensate water then, discharges by the vapor and water separator (3) of bottom.Because the aluminium powder coefficient of thermal conductivity is very high, it is very fast therefore to conduct heat, and the temperature of heating surface is very even, and the temperature difference of steam and condensate water and grey headwall is very little.

Claims

1. steam-heated dust collector ash hopper of heat-conducting type, form by grey headwall, coil pipe, aluminium powder packed layer, heat-insulation layer, conduit fittings etc., it is characterized in that: arrange snakelike metal coil pipe in the chuck between the grey headwall outside and heat-insulation layer, and the filling of the space outside coil pipe aluminium powder, be the medium augmentation of heat transfer with the aluminium powder layer.
