Description
Technical field
The utility model relates to a kind of energy-saving hot blast furnace.
Background technology
In daily production and the life process, often need use hot blast, to regulate the temperature of environment, for example mining, growing vegetables, animal feeding etc.At present, the acquisition mode of hot blast mostly produces steam, through air heat exchanger the mode of the heat transferred air of steam is obtained hot blast again through boiler.Aforesaid way is wanted earlier the water heating, i.e. the heat that fuel combustion produces can not directly exchange with air, and generation hot blast speed is slow, and owing to water will absorb great amount of heat, after boiler quits work, this part heat will waste, and cause the waste of the energy.
Summary of the invention
The technical problem that the utility model will solve is to above-mentioned defective, provides a kind of and produces that hot blast speed is fast, the hot-blast stove of energy savings.
In order to solve the problems of the technologies described above; The utility model provides a kind of energy-saving hot blast furnace with following structure; Its design feature is to comprise coal furnace, dirt pocket and the air heat exchanger that sets gradually; The gas approach of dirt pocket docks with the exhanst gas outlet of coal furnace, and the gas approach of air heat exchanger docks with the exhanst gas outlet of dirt pocket.
Said coal furnace comprises body of heater; The body of heater front end is provided with closed fuel inlet, is provided with interlayer in the body of heater, and interlayer is separated into the combustion chamber of bottom and the smoke output chamber on top with the body of heater inner chamber; Be provided with the revolution fire grate in the combustion chamber; The leading section of combustion chamber is provided with air inlet, rearward end is provided with slag notch, and the smoke output chamber front end is communicated with combustion chamber, and the smoke output chamber rear end is provided with exhanst gas outlet.
Said dirt pocket comprises the chamber body of both ends open, is connected with refractory masses on the inwall of chamber body.
Said air heat exchanger comprises housing, and the housing inner chamber is separated into three chambers in upper, middle and lower by two diaphragm plates, and the middle chamber front end is provided with gas approach, the rear end is provided with exhanst gas outlet, is provided with many heat exchanger tubes with upper chamber and lower chambers connection in the middle chamber; Upper chamber by last vertical clapboard be separated into the air-out chamber that is positioned at the housing front end be positioned at the housing rear end went up the wind passage, housing is provided with the hot-blast outlet that is communicated with the air-out chamber; Lower chambers is separated into by following vertical clapboard and is positioned at descending the wind passage and being positioned at the air-inlet cavity of housing rear end of housing front end, and housing is provided with the cold wind import that is communicated with air-inlet cavity.
Since the high-temperature flue gas that the utility model produces coal furnace through heat exchanger directly and air carry out heat exchange, saved and utilized water to do the intermediate link of medium in the prior art, accelerated the heat transfer rate greatly, it is in time rapid promptly to obtain hot blast, energy savings.
In sum, the advantage of the utility model is that hot blast produces in time rapidly good energy-conserving effect.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The utility model is following about the definition of direction: with the flue gas trend is reference, along the direction of flue gas trend be after, before the direction of contrary flue gas trend is.
As shown in Figure 1, energy-saving hot blast furnace comprises coal furnace 1, dirt pocket 2 and the air heat exchanger 3 that sets gradually.Said coal furnace 1 comprises body of heater 11; Body of heater 11 front ends are provided with closed fuel inlet 12, are provided with interlayer 13 in the body of heater 11, and interlayer 13 is separated into the combustion chamber 14 of bottom and the smoke output chamber 15 on top with body of heater 11 inner chambers; Be provided with revolution fire grate 16 in the combustion chamber 14; The front bottom end of combustion chamber 14 is provided with air inlet 18, the bottom, rear end is provided with slag notch 17, and smoke output chamber 15 front ends are communicated with combustion chamber 14, and smoke output chamber 15 rear ends are provided with exhanst gas outlet.The known technology that revolution fire grate 16 adopts for existing boiler, coal is fallen on the slow rotating revolution fire grate 16 from fuel inlet 12, and abundant burning back is delivered near the slag notch 17 by revolution fire grate 16.Preferably establish the refractory masses (not shown) on the inwall of body of heater 11, interlayer 13 is preferably also processed by refractory material.Said dirt pocket 2 comprises the chamber body 21 of both ends open, is connected with refractory masses 22 on the inwall of chamber body 21.Said air heat exchanger 3 comprises housing 31; Housing 31 inner chambers are separated into three chambers in upper, middle and lower by two diaphragm plates 32; The middle chamber front end is provided with gas approach, the rear end is provided with exhanst gas outlet, is provided with many heat exchanger tubes 37 with upper chamber and lower chambers connection in the middle chamber; Upper chamber be separated into by last vertical clapboard 33 the air-out chamber 34 that is positioned at the housing front end be positioned at the housing rear end went up wind passage 35, housing 31 is provided with the hot-blast outlet 36 that is communicated with air-out chamber 34; Lower chambers is separated into by following vertical clapboard 38 and is positioned at descending wind passage 39 and being positioned at the air-inlet cavity 40 of housing rear end of housing front end, and housing 31 is provided with the cold wind import 41 that is communicated with air-inlet cavity 40.The gas approach of above-mentioned dirt pocket 2 docks with the exhanst gas outlet of coal furnace 1, and the gas approach of air heat exchanger 3 docks with the exhanst gas outlet of dirt pocket 2.
During use, on air heat exchanger 3 exhanst gas outlets, will load onto deduster and air-introduced machine, also will adorn air-introduced machine at hot-blast outlet 36, above-mentioned deduster and air-introduced machine are all not shown in the drawings.The high-temperature flue gas that coal furnace 1 fuel combustion produces gets into dirt pocket 2 through the exhanst gas outlet of smoke output chamber 15 and its rear end; After the locular wall collision; big grit in the flue gas falls, and flue gas gets in the middle chamber of air heat exchanger 3 after dirt pocket 2 carries out dedusting, and discharges through the exhanst gas outlet that is located at the middle chamber rear end; Flue gas is through in the process of middle chamber; Cold air gets into air-inlet cavities 40 through cold wind import 41, and the heat exchanger tube 37 that gets into heat exchanger 3 rear portions then and flue gas carry out getting into after the heat exchange first time went up wind passage 35, and wind passage 39 was descended in entering after heat exchanger tube 37 and the flue gas that then gets into heat exchanger 3 middle parts carried out the heat exchange second time; Get into heat exchanger 3 anterior heat exchanger tubes 37 again and carry out getting into air-out chamber 34 after the heat exchange for the third time, after hot-blast outlet 36 outflows with flue gas.Flue gas is through in the process of middle chamber, and the path of cold air is a roundabout, is more conducive to like this carry out sufficient exchange heat with flue gas.
