Description
Technical field
The utility model relates to a kind of device with coal production coal gas, especially a kind of full water jacket industrial gas producer.
Background technology
Industrial gas generating furnace is to be raw material with coal, with the gas mixture of air and water vapor as vaporized chemical, by certain processing method make coal be converted into coal gas modern age the advanced person energy device.With directly be that fuel is compared with the coal, use producer gas generator, can reduce environmental pollution on the one hand, can save a large amount of energy on the other hand, can also reduce labour intensity greatly.The tradition producer gas generator primary structure as shown in Figure 3, Figure 4:
(1) main part (Fig. 4): adopt and to build firebrick structure in the steel plate cylinder, join local water jacket 1 ' products for steam (type of furnace that has because of adopt outer supply steam do not have this local water jacket 1 '), by tracheae and gas bag 2 ' be connected.The lid on main body top adopts the refractory concrete structure.The passage that the bottom is provided with a wind plays pneumatolysis to fuel.
(2) air-blast system: generally by centrifugal blower 3 ', pipeline, and instrument is formed.
(3) steam system: generally by gas bag 2 ', valve body, pipeline and hot water jacket 1 ' (or external steam) is formed.
(4) coaling machine structure: mechanical coaling machine with coal by cart transport to the coal bunker 4 at main body top ' in.Need join in the burner hearth again by producing.
(5) ash discharging gear: utilize ash-pan 5 ' rotational automatic deslagging.
(6) cleaning apparatus and power distribution system.
The main drawback of above traditional producer gas generator is: be the burner hearth that is built into refractory brick in the main part cylinder, in all processes, if refractory brick comes off or sealing property is bad, main part cylinder steel body just burns easily, burn, the work-ing life and the safety performance of main part reduce greatly.Because steam system is used gas bag, there is potential safety hazard simultaneously.
Also there is main part to adopt the producer gas generator of full water jacket, as Chinese patent ZL 01270433.4 disclosed " producer gas generator ", its body of heater is made of flue and boiler clothing, between flue and boiler clothing heating water jacket and the steam generating chamber that constitutes stove and accessory, but it does not illustrate flue, the boiler clothing and the concrete structure of water jacket between the two, and the position that is provided with of pressure release blow-down pipe and steam outlet pipe all is starkly lower than the flue tip position from its drawing, therefore do not have the function of full water jacket, there is the defective that the danger burnt and steam can't smooth and easy eliminating in flue top, and have malleation between flue and the boiler clothing, to the requirement height of material, thereby cost of manufacture is high and have a potential safety hazard.
In addition, the air-blast system of above-described producer gas generator and steam system as shown in Figure 7, its air feed craft route is:
Therefore the steam that comes from gas bag must need certain malleation, could be with the air admission burner hearth that blasts through gas blower, thereby gas bag generally need be set with stable and guarantee the pressure of steam in steam system.
Based on the above, necessary existing producer gas generator is undergone technological transformation, to overcome its existing problem.
Summary of the invention
First technical problem to be solved in the utility model is to provide a kind of main part of gas furnace not exist to be burnt, burn danger, the full water jacket industrial gas producer that long service life and safety performance are good at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this full water jacket industrial gas producer, it has body of heater, have gas exit on the body of heater, coal mechanism is equipped with at the top of body of heater, ash discharging gear is equipped with in the bottom, the bottom of body of heater also is provided with furnace bottom airduct from water vapor to the body of heater internal furnace that carry air and, the round shape part and the header field that it is characterized in that described body of heater are double-deck whole steel sheet structure, thus in body of heater, form the successive intercalated water sleeve between the skin, the bottom of water jacket is connected with water inlet pipe, outer the covering of top cover has vapour outlet, also have the water outlet that is communicated with water jacket on the outer side wall of body of heater, water outlet is connected with upflow tube, and water level is between the enclosing cover and inner cap of body of heater top cover in this upflow tube may command water jacket.
Described outer covering also has the air blast inlet, and this blast inlet is connected with gas blower by pipeline, and described vapour outlet then is connected with described furnace bottom airduct by steam-pipe.In addition, also can outside described, cover or steam-pipe on steam outlet is set, to solve the too much processing of excessive part steam under the situation of steam that water jacket produces.
Described upflow tube has one section " U " shape part, and the lower-most point of the tube chamber of upflow tube position highest point is between the enclosing cover and inner cap of body of heater top cover.The shape of upflow tube does not have special restriction, it is following or equal with water level only to need its inlet end to be located at the interior water level of water jacket, and the lower-most point of the tube chamber of exit end highest point satisfies aforementioned requirement and gets final product, but adopts " U " shape tubular construction, can form fluid-tight preferably comparatively speaking.
/ 3rd to 2/3rds places of the lower-most point of the tube chamber of described upflow tube position highest point spacing between the enclosing cover of body of heater top cover and inner cap; such position is provided with; both helped guaranteeing inner cap above be coated with competent liquid water; to play the good cooling provide protection; leave enough spaces for again steam, air in the following space of the above enclosing cover of water level, so that it flows smoothly and discharges.
Advantage of the present utility model is: 1, because the cylindrical part of body of heater is divided into double-layered cylinder whole steel sheet structure, the exterior and interior cover of body of heater top cover also is a whole steel sheet, between inside and outside two lids is water and vapor film, reaches exterior and interior cover interlayer certain altitude between the ectonexine cylinder of body of heater and is softening water.The inner chamber of body of heater is burner hearth, and all body of heater does not need refractory materialss such as refractory brick.Body of heater in the utility model, it between the double-layered cylinder softening water, inner layer cylinder there is cooling effect all the time, make the inner ring cylinder avoid Yin Wendu too high and burn, the heat that softening water in the interlayer can fully absorb again in the burner hearth produces steam for gas gasification use in the burner hearth, the work-ing life and the security that have improved the producer gas generator body of heater greatly.2, vapor system has saved gas bag and annex thereof, moreover since from blower fan to full water jacket samdwich until burner hearth, whole gas flow is unimpeded, full water jacket main body is atmospheric pressure state in process of production, so compare and existing industrial gas generating furnace, whole device ' improves and the cost of manufacture reduction.3, the water level in the water jacket can be observed ocular and clear by outside upflow tube control.4, structure is compact, simple to operation more, in actual production, need only regulate the size that the gas blower butterfly valve just can be controlled required coal gas amount.5, through practical application, coal consumption reduces more than 35%.
