Abstract
The utility model is related to hot-blast stove, particularly a kind of hot-blast stove heat exchanger.Including heat exchanger body, the heat exchanger body is placed in the burner hearth of hot-blast stove, helically pipeline structure, and one end is connected with wind powder mixed pipe line, and the other end is bell-mouth structure of air, bell-mouth structure of air correspondence burner.Mixed gas containing coal dust are when through over-heat-exchanger, fugitive constituent is lighted first in heat exchanger, secondly because accumulated temperature is stepped up, fixed carbon is ignited, under the double action of self heat and external radiation heat, coal dust fully burns, flame of the row into temperature more than 1300 degrees Celsius at nozzles is being sprayed, the thermal efficiency of hot-blast stove had both been improve, inferior fuel can be being made full use of again, save fuel, reduces cost.
Description
Technical field
The utility model is related to hot-blast stove, particularly a kind of hot-blast stove heat exchanger.
Background technology
At present, hot-blast stove is widely used, and hot-blast stove is including chain furnace, fluidized bed furnace, dust stove and handwarmer etc.,
Fuel combustion efficiency varies, it is impossible to meet the requirement of energy saving, and especially dust stove, and wind powder is direct through wind powder mixed pipe line
Burner combustion is sprayed to, because wind powder temperature is relatively low, fuel combustion is insufficient, waste the energy.
Utility model content
In order to solve the above technical problems, the utility model provides one kind allows the fuel to fully burning, the heat of energy saving
Wind furnace heat exchanger.
The technical scheme in the invention for solving the above technical problem is:
A kind of hot-blast stove heat exchanger, including heat exchanger body, the heat exchanger body are placed in the stove of hot-blast stove
In thorax, helically pipeline structure, one end is connected with wind powder mixed pipe line, and the other end is bell-mouth structure of air, bell-mouth structure of air correspondence
Burner.
Using the utility model of above-mentioned technical proposal, compared with prior art, beneficial effect is:
Mixed gas containing coal dust first light fugitive constituent in heat exchanger when through over-heat-exchanger,
Secondly because accumulated temperature is stepped up, fixed carbon is ignited, and under the double action of self heat and external radiation heat, coal dust fills
Divided combustion, is spraying flame of the row into temperature more than 1300 degrees Celsius at nozzles, improves the thermal efficiency of hot-blast stove, saves fuel,
Reduces cost.
Further, prioritization scheme of the present utility model is:
The heat exchanger body is isometrical cylindrical screw pipeline structure or Reducing screw pipeline structure.
The spiral pipeline is heat resisting pipe.
Brief description of the drawings
Fig. 1 is the utility model embodiment use state structural representation;
Fig. 2 is that heat exchanger body is Reducing screw pipeline structure schematic diagram;
In figure:Body of heater 1;Burner hearth 2;Water cooling tube 3;Drum 4;Heat exchanger body 5;Fix bar 6;Wind powder mixed pipe line 7;Combustion
Burner 8.
Specific embodiment
The utility model is described in detail in detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, a kind of hot-blast stove heat exchanger, hot-blast stove is pulverized-coal fired boiler.Heat exchanger body 5 is placed in body of heater 1
Burner hearth 2 in, the both sides of burner hearth 2 are provided with water cooling tube 3, and the top of burner hearth 2 is provided with drum 4, and the bottom of burner hearth one end is provided with burning
Device 8.Heat exchanger body 5 is isometrical cylindrical screw pipeline structure, and material is heat resisting pipe;The one end of heat exchanger body 5 and wind
Powder mixed pipe line 7 is connected, and the other end is bell-mouth structure of air 5-1, bell-mouth structure of air 5-1 correspondence burners 8, the axle of heat exchanger 5
Line is arranged with horizontal plane.
Heat exchanger body 5 can also be Reducing screw pipeline structure(Shown in Fig. 2).
Operationally, the mixed gas containing coal dust are first in heat exchanger when through over-heat-exchanger for the utility model
First fugitive constituent is lighted, secondly because accumulated temperature is stepped up, fixed carbon is ignited, in the double of self heat and external radiation heat
Under recast is used, coal dust fully burns, flame of the row into temperature more than 1300 degrees Celsius at the bocca of bell-mouth structure of air 5-1,
Both the thermal efficiency of hot-blast stove had been improve, inferior fuel can have been made full use of again, saved fuel, reduces cost.
The preferably feasible embodiment of the utility model is the foregoing is only, not thereby limits to power of the present utility model
Sharp scope, the equivalent structure change that all utilization the utility model specifications and accompanying drawing content are made, is both contained in the utility model
Interest field within.
