Abstract

The utility model relates to a reverse combustion type garbage cremation furnace, which is characterized in that a circular water cooling interlayer is arranged between the inner wall of the furnace body and a circular flue. The upper part of the furnace body inner cavity formed by the circular flue inner wall is a storage bin, and the lower part is a flared reverse combustion burner. The outer wall of the burner and the inner wall of the circular flue form a circular cooling air bin together. The cooling air bin is communicated with the air source through an air inlet flue, and the ash bin communicated with the flue is arranged in the lower part of the burner. The casing of the flared reverse combustion type burner is distributed evenly with air inlets. A grate is arranged at the awl mouth point of the burner, and the interior of the combustion chamber under the grate is filled with multi pore space fillers made of high temperature refractory materials.

Description

The counter-burning type refuse incinerator
The utility model relates to a kind of incinerator that is used to burn away the refuse, and relates to a kind of counter-burning type refuse incinerator specifically.
Refuse pollution has become big public hazards, and this problem just seems particularly outstanding in developed country and area.The mode that many both at home and abroad at present employings are buried or burned is handled rubbish.More existing small incinerators can not make rubbish completing combustion because its structure is unreasonable, easily cause secondary pollution, and can not be widely used.Though also there are some incinerators that rubbish is fully burnt, because of first complex structure, the 2nd, need there be auxiliary equipment combustion-supporting during burning, cause increasing of operating cost, and can not get applying.
The purpose of this utility model provides a kind of auxiliary equipment that do not need can make rubbish clean-burning with regard to being to overcome above-mentioned weak point of the prior art, and there is not secondary pollution, simple and reasonable, safe in utilization, reliable, and can be the counter-burning type refuse incinerator that the user provides steam or hot water.
The purpose of this utility model can adopt following measure to realize:
The architectural feature of the utility model counter-burning type refuse incinerator is as follows: be provided with annular water-cooled interlayer between inboard wall of furnace body and annular flue, the top of the body of heater inner chamber that is made of annular flue inwall is feed bin, the bottom is tubaeform counter-burning type burner, the common formation of burner outer wall and annular flue inwall one annular cooling air storehouse, the cooling air storehouse communicates with wind regime by air inlet duct, and the grey storehouse that communicates with flue is arranged on the bottom of burner; Be furnished with fresh air inlet on the housing of tubaeform counter-burning type burner, fire grate is arranged on the awl mouth place of burner, be filled with the porous crack charges that are made by high-temperature refractory in the combustion chamber below stove is calculated, the above awl mouth section of its fire grate is the ignition zone, and the drum-shaped section of its underpart is the oxidation burning-out zone.
For making rubbish in the counter-burning type burner, be in optimal combustion state, the experiment proved that, the intake of ignition zone is preferably 1: 2 with the ratio of oxidation burning-out zone intake, for realizing this proportioning, taked following scheme to realize in the utility model, that is, make that to be opened in area sum that awl mouthful section in tubaeform counter-burning type burner top goes up fresh air inlet be to be positioned at 1/2nd of air intake hole area sum on the drum-shaped section of its underpart; Be opened in the aperture that awl mouthful section in tubaeform counter-burning type burner top goes up fresh air inlet on fresh air inlet and the bottom drum-shaped section specifically and equate that the quantity of fresh air inlet is the twice that awl mouthful section goes up the air intake hole number on the drum-shaped section.Certainly also can adopt other method to realize two-to-one air intake proportional quantity.
For obtaining heat insulation effect preferably, between the inside and outside wall of body of heater, be filled with insulation material; The chimney that communicates with annular flue is arranged on the top of body of heater.
Advantage of the present utility model do not need to be any auxiliary equipment that rubbish is fully burnt, and do not have secondary pollution, and structure tube list is reasonable, and is safe in utilization, reliable, and can be the user steam or hot water are provided.
Accompanying drawing is the front view of the utility model structure.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
As shown in the figure, between the body of heater that has the insulation interlayer (3) inwall and annular flue (5), be provided with and have the cooling cooling effect, and can be the annular water-cooled interlayer (4) that the user provides steam or hot water; Top by the body of heater inner chamber of (5) wall formation in the annular flue is feed bin, feed bin is provided with gallery ports (12), the bottom is a tubaeform counter-burning type burner (7), be evenly equipped with the identical fresh air inlet in aperture on the housing of tubaeform counter-burning type burner, the quantity of fresh air inlet is the twice that awl mouthful section in top goes up the air intake hole number on the drum-shaped section of its underpart, fire grate (6) is arranged on the awl mouth place of burner, be filled with the porous crack charges (g) that are made by high-temperature refractory in the combustion chamber below stove is calculated, the above awl mouth section of its fire grate (6) is the ignition zone, and the drum-shaped section of its underpart is the oxidation burning-out zone; The common formation of an ancient piece of jade, round, flat and with a hole in its centre one annular cooling air storehouse in burner outer wall and the annular flue, the cooling air storehouse is connected with blower fan (8) by air inlet duct, the grey storehouse that communicates with flue is arranged on the bottom of the fly-ash filter (10) of burner bottom setting, the shoot door (11) that communicates with grey storehouse is installed on the body of heater, and shoot door (11) is provided with the flame observation window; The chimney (1) that communicates with annular flue is arranged on the top of body of heater; The top of body of heater also is provided with the hoisting ring (2) that is used to lift by crane.
The course of work of the present utility model is as follows:
Ignition substance after at first will lighting drops into the ignition zone of feed bin base burning device from Jia Kemen, again rubbish (combustible garbage) is added in the feed bin, start the blower fan air-supply after closing gallery ports, this moment is as long as the suitable air quantity of control can realize controlling the burning velocity of ignition zone, the a large amount of carbon monoxide, carbon black particle and other material that are contained in the flammable flue gas that forms after the burning of ignition zone carry out second-time burning in the high temperature burning-out zone of being made of porous crack charges in fire grate enters the oxidation burning-out zone downwards.The high-temperature flue gas that forms after fully oxidation is fired to the greatest extent is downwards by grey storehouse after by the upwards discharge of annular flue, simultaneously with the working medium (water) of heat entrained in the flue gas in annular water-cooled interlayer transmits interlayer, make it to generate steam or hot water, high-temperature flue gas then enters atmosphere via the low-temperature flue gas that forms 200~300 ℃ behind the working medium absorbing and cooling temperature by chimney.The cooling of a burner body is that the cold wind that provides by blower fan is realized.
