Description
Technical field
The utility model belongs to hazardous waste equipment of rotary kiln incineration field, relates to a kind of tandem water-cooled furnace door short section for industrial hazardous waste rotary kiln combustion furnace, is particularly useful for being connected between Rotation error and feeder.
Background technology
Current China is to the processing method of industrial dangerous waste, and the general rotary kiln type incinerator that adopts processes, and in rotary kiln front end, feeder is housed, is connected to a fire door pipe nipple between feeder and Rotation error charging aperture.Domestic used fire door pipe nipple at present, what have makes frame-type with heat resisting cast steel; The dull and stereotyped jacket type of some employings, stay bolt bar is evenly covered with between chuck, logical cooling water forced circulation in chuck, cooling water after softening is entered from cooling water inlet, the front end of water-cooled furnace door short section is entered into by bottom chuck, rise through side chuck and converge to coolant outlet, so far completing the forced circulation of whole cooling water, ensure that water-cooled furnace door short section normal work in high temperature environments.
The feeder fire door pipe nipple used at present, the frame-type structure made with heat resisting cast steel, although structure is simple, because this part is placed in rotary kiln, the temperature in rotary kiln is very high, causes fire door pipe nipple to be heated generation gross distortion, causes feeder normally to work.Adopt dull and stereotyped jacket type fire door pipe nipple, although solve the problem of fire door pipe nipple temperature distortion, but because chuck is flat stressed bad, a lot of stay bolt bar need be welded between chuck, because weld seam density is comparatively large, add upper flat plate chuck stressed bad, work in high temperature environments again, service time one is long, just occurs crackle at the anterior stay bolt bar weld seam of fire door pipe nipple or housing angle welding place, causes the cisco unity malfunction that leaks.
Summary of the invention
Problem to be solved in the utility model is, overcome the deficiencies in the prior art, a kind of tandem water-cooled furnace door short section for industrial hazardous waste rotary kiln combustion furnace is provided, adopt the fire door pipe nipple of the semicircle steel pipe chuck of tandem, structure is both simple, temperature distortion problem can be solved again, the instructions for use under hot environment can be met.
The utility model solves its technical problem and takes following technical scheme to realize:
According to a kind of tandem water-cooled furnace door short section for industrial hazardous waste rotary kiln combustion furnace that the utility model provides, comprise housing and the flange be connected with feeder that housing is equipped with, fire access, gusset, fire door flashboard, cooling tube, described cooling tube is that tandem is contained on the outer surface of housing, cooling water inlet and coolant outlet are all arranged on the cooling tube medium position of housing bottom surface, the position of coolant outlet is located at above the position of cooling water inlet, the flange be connected with feeder is arranged on the left end of housing, fire access to be arranged on the side near left end and to pass in housing, link of boards is in the junction of flange and housing, fire door flashboard is contained in the housing between flange and cooling tube, and can move up and down.
It is take following technical scheme to realize further that the utility model solves its technical problem:
Aforesaid cooling tube adopts semicircle steel pipe chuck form to make.
The utility model compared with prior art has significant advantage and beneficial effect:
Because the utility model adopts the fire door pipe nipple of the semicircle steel pipe chuck of tandem, cooling water after softening is flowed into from cooling water inlet, first the bottom righthand side of water-cooled furnace door short section is entered into by cooling tube, temperature is the highest herein, position is minimum, through the convoluted flow of cooling tube to left direction, finally discharges from coolant outlet, so far complete the forced circulation of whole cooling water, ensure that water-cooled furnace door short section normal work in high temperature environments.
Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to detailed description of the invention, structure, feature and effect thereof of providing according to the utility model, be described in detail as follows.
A kind of tandem water-cooled furnace door short section for industrial hazardous waste rotary kiln combustion furnace as shown in Fig. 1 ~ 5, comprise housing and the flange be connected with feeder that housing is equipped with, fire access, gusset, fire door flashboard, cooling tube, described cooling tube 9 is contained on the outer surface of housing 8 for cascade, cooling tube adopts semicircle steel pipe chuck form to make, cooling water inlet 1 and coolant outlet 2 are all arranged on the cooling tube medium position of housing bottom surface, the position of coolant outlet is located at above the position of cooling water inlet, the flange 3 be connected with feeder is arranged on the left end of housing, fire access 4 to be arranged on the side near left end and to pass in housing, gusset 5 is connected to the junction of flange and housing, fire door flashboard 6 is contained in the housing between flange and cooling tube, and can move up and down.
Workflow: first the cooling water after softening is entered from cooling tube import 1, first the middle part of the bottom righthand side of water-cooled furnace door short section is entered into by cooling tube, temperature is the highest herein, position is minimum, through the convoluted flow of cooling tube to left direction, finally discharged by coolant outlet 2, so far complete the forced circulation of whole cooling water, ensure that water-cooled furnace door short section normal work in high temperature environments.Cooling tube 9 in water-cooled furnace door short section all adopts tandem semicircle steel pipe chuck form, and do chuck with semicircle steel pipe stressed very good, manufacturing process is simple, can reduce a lot of cost.Owing to adopting semi-steel pipe to do the design that chuck is convenient to cooling duct, cooling duct can be made to design more meet Thermodynamic Law.First cooling water enters into the middle part of the bottom righthand side of fire door pipe nipple, temperature is the highest herein, then progressively spiral and move to left, finally discharge from following delivery port, this series circuit, cooling water flow velocity is very fast, circulate smooth and easy, not easily block, the heat this ensures that thered suffered by fire door pipe nipple is taken away in time by cooling water, make the temperature of fire door pipe nipple can not be too high, ensure that water-cooled furnace door short section normal work in high temperature environments.The utility model is connected between Rotation error 7 and feeder.
