Abstract
The utility model relates to a hot blast stove capable of recycling tail gas waste heat, comprising a hearth and a heat exchanger, wherein the hearth is communicated with the heat exchanger through a smoke passage, a hot blast stove feed port is arranged in the front of the hearth; after the hearth is communicated with the heat exchanger, insulating layers are respectively arranged at two sides of the hearth and the heat exchanger, the heat exchanger is communicated with the insulating layer through the smoke passage; a smoke outlet is arranged at bottom of the insulating layer to discharge the tail gas of which the waste heat is used; the hot blast stove capable of recycling tail gas waste heat is simple in structure; since the insulating layers are arranged at two sides of the hearth and the heat exchanger, the waste heat in high-temperature smoke can be sufficiently used so as to achieve the aim of sufficiently recycling the resource.
Description
Technical field
The utility model relates to the hot-blast stove technical field, specifically is a kind of hot-blast stove that using waste heat from tail gas utilizes again that has.
Background technology
Hot-blast stove as thermal power machinery begins extensive use in the seventies in 20th century in China, and it has become the regeneration product of electric heat source and traditional steam power thermal source in many industries.Along with the development of medium-sized and small enterprises and the improvement of family housing, demand to hot-blast stove is more and more, particularly those utilize the unit that hot-air is dried and warmed oneself, and store industry, food-processing industry, Chinese medicinal herbs industry etc. as grain, all combustion heat wind furnace are had very big demand.Hot-blast stove generally all acts as a fuel with fire coal, the remaining stalk of fuel oil and rural area etc. at present, the flue gas tail gas that fuel produces after the burner hearth internal combustion is directly to discharge from exhaust opening, the temperature of discharging flue gas tail gas is higher, therefore with the direct discharge of high-temperature flue tail-gas waste to heat energy, in the prior art, do not have to utilize and discharge the equipment that the extraction heat utilizes again the high-temperature flue tail-gas from exhaust opening.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can utilize the hot-blast stove that using waste heat from tail gas utilizes again that has of discharging heat the high-temperature tail gas from exhaust gases passes.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of have a hot-blast stove that using waste heat from tail gas utilizes again, comprise a burner hearth and a heat exchanger, be communicated with by exhaust gases passes between described burner hearth and the heat exchanger, be shaped on the hot-blast stove charging aperture in the front portion of described burner hearth, it is characterized in that, described burner hearth and heat exchanger are after being communicated with, and the both sides of burner hearth and heat exchanger are provided with heat-insulation layer, also are connected by exhaust gases passes between described heat exchanger and heat-insulation layer.
Described heat-insulation layer bottom is provided with exhaust opening, and the tail gas after the UTILIZATION OF VESIDUAL HEAT IN is discharged.
Operation principle of the present utility model is, fuel is put into burner hearth by the hot-blast stove charging aperture to burn, the high-temperature flue gas of burning enters the heat exchanger from exhaust gases passes, high-temperature flue gas in heat exchanger after, enter heat-insulation layer by exhaust gases passes once more, high-temperature flue gas carried out waste heat and utilized in heat-insulation layer this moment, after exhaust opening discharge.
The beneficial effects of the utility model are simple in structure, have increased heat-insulation layer at burner hearth and heat exchanger both sides, can make full use of the waste heat that contains in the high-temperature flue gas, resource is reached fully again utilize.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of have a hot-blast stove that using waste heat from tail gas utilizes again, comprise a burner hearth 1 and a heat exchanger 2, be communicated with by exhaust gases passes 3 between burner hearth 1 and the heat exchanger 2, be shaped on hot-blast stove charging aperture 11 in the front portion of burner hearth 1, be used for fuel and enter burner hearth 1 burning, at burner hearth 1 with after heat exchanger 2 is communicated with, the both sides of burner hearth 1 and heat exchanger 2 are shaped on heat-insulation layer 4, also be connected between heat exchanger 2 and the heat-insulation layer 4 simultaneously, will enter in heat-insulation layer 4, carry out waste heat and utilizing by the high-temperature flue gas in the heat exchanger 2 by exhaust gases passes 3, and heat-insulation layer 4 bottoms also are shaped on exhaust opening 41, well the tail gas after the UTILIZATION OF VESIDUAL HEAT IN are discharged.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. one kind has the hot-blast stove that using waste heat from tail gas utilizes again, comprise a burner hearth and a heat exchanger, be communicated with by exhaust gases passes between described burner hearth and the heat exchanger, be shaped on the hot-blast stove charging aperture in the front portion of described burner hearth, it is characterized in that, described burner hearth and heat exchanger are after being communicated with, and the both sides of burner hearth and heat exchanger are provided with heat-insulation layer, also are connected by exhaust gases passes between described heat exchanger and heat-insulation layer.
