The utility model is characterized in that an upper temper zone intake chamber, a middle gas gathering chamber and a lower normalized zone intake chamber are formed between the outer wall of a furnace body and the outer walls of a normalized zone and a temper zone; the normalized zone intake chamber and the temper zone intake chamber are respectively communicated with the normalized zone and the temper zone through air inlets; the gas gathering chamber is communicated with the inner part of the furnace through gas outlets, and the normalized zone intake chamber and the temper zone intake chamber are respectively provided with a gasifying agent intake tube and a gas outlet pipe. The utility model has the advantages that intake air forms rotary air current and is sufficiently preheated, the carbon content in ash is reduced, the post-treatment is simplified, the utility model has the dual functions of tempered and normalized gas generating furnaces, and the applicable hot gas can be directly supplied.
Description
The utility model relates to and a kind of raw coal is become the generation equipment of coal gas by gasification, exactly, is a kind of two-way producer gas generator.
At present, the kind of coal gas translating eqipment is more, can reduce two kinds, and a kind of is bottom blowing type, is about to air and blows in the stove from furnace bottom, and coal gas is blown from furnace roof, is called normalizing furnace; Another kind is that air is arranged in the vacuum pump inspiration stove of furnace bottom from furnace roof, becomes coal gas by high-temperature gasification and is sucked out, and is called anti-stove.All there is certain shortcoming in these two kinds of producer gas generators, and the gas quality of normalizing furnace output is poor, need complicated treatment facility, and there is the high shortcoming of carbon content in the lime-ash in anti-stove, produce very difficulty of heating gas.
The purpose of this utility model is at above-mentioned deficiency of the prior art the structure of combustion parts to be improved, particularly realize that with simple structure air inlet can form swirling eddy, and obtain abundant preheating, reduce cindery carbon content to reach, simplify rearmounted the processing, the purpose of suitable heating gas can directly be provided.
The purpose of this utility model realizes with following technical scheme: for comprising body of heater 1, fire door 2, bell 3, coal bunker 4, back fire section 5, normalized zone 6, water jacket 13, cinder chamber 14, the producer gas generator of grate 18, key is the inwall and the back fire section 5 of body of heater 1, form the interlayer air chamber between the outer wall of normalized zone 6, the interlayer air chamber is separated into the back fire section inlet plenum 7 on top, the coal gas collection chamber 9 at middle part and the normalized zone inlet plenum 8 of bottom, back fire section inlet plenum 7 communicates by air inlet port 16 and back fire section 5, coal gas collection chamber 9 by coal gas portal 17 and center ovens in communicate, normalized zone inlet plenum 8 communicates by air inlet port 20 and normalized zone 6, also is respectively equipped with on the body of heater 1 and back fire section inlet plenum 7, coal gas collection chamber 9, the vaporized chemical inlet pipe 11 that normalized zone inlet plenum 8 communicates, coal gas escape pipe 10, vaporized chemical inlet pipe 12.
Vaporized chemical inlet pipe 11,12 is provided with along the outer wall tangent line of back fire section inlet plenum 7, normalized zone inlet plenum 8, can certainly, also can make the axis of inlet pipe and tangent line form certain angle along the tangent line setting of any point, and purpose is to strengthen swirling eddy.
In addition, can design vaporized chemical inlet pipe 11,12 and be arranged at the bottom of back fire section inlet plenum 7 and the top of normalized zone inlet plenum 8 respectively, to increase warm up time.
Gasification principle of the present utility model is as follows: raw coal is housed in the stove, air or steam are from vaporized chemical inlet pipe 11 after raw coal is ignited, 12 carry out preheating by back fire section inlet plenum 7 and normalized zone inlet plenum 8 respectively, enter in the stove through air inlet port 16, because of vaporized chemical inlet pipe 11,12 and air inlet port 16,20 in body of heater center one-tenth miter angle, make air and steam at two inlet plenums 7,8 form swirling eddy, obtain abundant preheating, the high temperature swirling eddy is by air inlet port 16 then, 20 enter in the stove, carbon and airborne oxygen in the raw coal are reacted, produce the gasification layer obtains needs by reduction coal gas, assemble after coal gas escape pipe 10 flows out by coal gas collection chamber 9, in this process, because being portalled to middle part coal gas by two ends up and down, air and steam 17 flows out, just form following level, (from top to bottom) raw material layer, drying layer, do the slide layer, reducing zone, reducing zone, the gasification layer, ash bed.Said vaporized chemical is meant air, oxygen, steam or gas mixture.Because coal bunker stores certain coal amount, can make this stove move a few hours to tens hour continuously, because the principle of back fire section and anti-stove is identical, when promptly tar that is discharging in raw coal do to slip layer and sulfide and some other material favorable currents are by heat zone by burning-off, also played simultaneously combustion-supporting effect, make rearmounted treatment facility simple, again because the gasification principle of normalized zone is identical with normalizing furnace, fuel is through after the burning of back fire section, form heat zone once more, flow out from coal gas escape pipe 10 by reduction output high temperature carbon monoxide and hydrogen, thereby guaranteed the quality of coal gas, it is minimum that carbon content in the lime-ash is dropped to, and it is simple to have reached equipment, the efficient height, the purpose of heating gas can directly be provided for some heating installations.By changing the tolerance of vaporized chemical inlet pipe 11,12, can obtain anti-stove and normalizing furnace and two-way producer gas generator, can produce various coal gas.
Improvement of the present utility model has reduced cindery carbon content, has simplified rearmounted processing, and is simple in structure, convenient and practical, has the two-fold advantage of anti-stove and normalizing furnace, is a kind of comparatively ideal coal gas generation equipment.
Fig. 1 is a structure diagram of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model is made up of body of heater 1, fire door 2, bell 3, coal bunker 4, back fire section 5, normalized zone 6, back fire section inlet plenum 7, normalized zone inlet plenum 8, coal gas collection chamber 9, water jacket 13, cinder chamber 14, cleanout door 15, grate 18, following slag device 19 and vaporized chemical inlet pipe 11,12, coal gas escape pipe 10 etc.Wherein, the inwall of body of heater 1 and back fire section 5, form the interlayer air chamber between the outer wall of normalized zone 6, the interlayer air chamber is separated into the back fire section inlet plenum 7 on top, the coal gas collection chamber 9 at middle part and the normalized zone inlet plenum 8 of bottom, back fire section inlet plenum 7 communicates by the air inlet port 16 and the back fire section 5 on top, the coal gas of coal gas collection chamber 9 by the middle part portal 17 and stove in communicate, normalized zone inlet plenum 8 communicates by the air inlet port 20 and the normalized zone 6 of bottom, and, vaporized chemical inlet pipe 11,12 along back fire section inlet plenum 7, the outer wall tangent line of normalized zone inlet plenum 8 is provided with, and lays respectively at the bottom and the top of 2 air chambers.
