Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 shows the overall structure of the application;
Wherein, 1. bocca; 2. air inlet pipe; 3. intake valve; 4. air outlet valve; 5. liquefied room; 6. shower nozzle; 7. outlet valve.
Detailed description of the invention
For making the object of the application and technical scheme clearly, be clearly and completely described below in conjunction with the technical scheme of the embodiment of the present application to the application.Obviously, described embodiment is a part of embodiment of the application, instead of whole embodiments.Based on the embodiment of described the application, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the application's protection.
As shown in Figure 1, a kind of environment-protecting type exhaust air combustion furnace, comprise outer courage, inner bag is provided with in described outer courage, one end of described inner bag is provided with air inlet, one end that described air inlet is opposing is provided with gas outlet, the madial wall of described inner bag is provided with several boccas 1, each bocca 1 is all connected in air inlet pipe 2; The air inlet of described inner bag is connected with exhaust input tube road, and junction is provided with intake valve 3, and the gas outlet of described inner bag is connected with the one end in exhaust output tube road, and junction is provided with air outlet valve 4, and described intake valve 3 is check valve with air outlet valve 4; The other end in described exhaust output tube road is connected with liquefied room 5.
Such design sends into inner bag in order to realize waste gas from air inlet, burnt gas is sent from the gas outlet of inner bag, in addition, according to the pressure of inner bag combustion gas, this two places one-way cock can realize auto-admission and give vent to anger, avoid combustion furnace sky to burn or because the burning gases sent into are too much, cause that pressure in combustion furnace is excessive causes accident.
The arrival end of described liquefied room 5 is connected with exhaust output tube road, and the port of export of liquefied room 5 connects the pipeline for carrying water, and junction is provided with outlet valve 7.The top of described liquefied room 5 madial wall is provided with several shower nozzles 6 for spraying water.
Such design be to burning after the purification again of waste gas, prevent because burning insufficient, also harmful element is mingled with in waste gas, discharge into the atmosphere like this, can to environment, the design is by spray washing, and waste gas is soluble in water, is then discharged into by liquefied room 5 port of export together in the pipeline of conveying water in company with water.The port of export of liquefied room 5 connects the pipeline for carrying water, and junction is provided with outlet valve 7, the setting of outlet valve 7 is mainly in order to realize automation, simultaneously, ensure that waste gas fully contacts with shower water, waste gas can as much as possiblely to dissolve in water, and only have the water yield in liquefied room 5 reach a certain amount of after, outlet valve 7 just can be opened and discharge.
Preferably, inner bag described in the application is rotary structure, facilitates circumference to arrange bocca 1, farthest can utilize the working face of inner bag, that can increase burning gases with contact area that is combustion flame simultaneously, is beneficial to the Thorough combustion of waste gas.And rotary structure is easily placed in workshop, floor space is less.
Preferably, outer courage described in the application is tubular structure.Tubular structure is easily placed in workshop, and floor space is less, and convenient processing, save cost.
An embodiment of the application is provided with heat exchanger between inner bag and outer courage, because inner bag combustion will inevitably form a large amount of heats, this is write heat and exchanges to space outerpace in time by object exactly that arrange heat exchanger between inner bag and outer courage, can be used, also can be discharged in air, heat exchanger is not set, the temperature of combustion furnace inner bag and outer courage can be caused too high, easily burn out device, and be prone to accidents.
Another embodiment of the application is full of water in the cavity that formed between described inner bag and outer courage, and wall of outer container offers for the water inlet to water filling in this cavity and the delivery port for draining.Like this, the amount of heat that burning is formed just need not be wasted, and for heating water, by delivery in other production process, saves the energy, and decreases the discharge capacity to air.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, and all terms used herein (comprising technical term and scientific terminology) have the meaning identical with the general understanding of the those of ordinary skill in field belonging to the application.Should also be understood that those terms defined in such as general dictionary should be understood to have the meaning consistent with the meaning in the context of prior art, unless and define as here, can not explain by idealized or too formal implication.
The implication of the "and/or" described in the application refers to respective individualism or both simultaneous situations include interior.
With the above-mentioned desirable embodiment according to the application for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this application technological thought, can carry out various change and amendment completely.The technical scope of this application is not limited to the content on description, must determine its technical scope according to right.
