Abstract
An indirect heating hot-air furnace comprises a firebox in the furnace, multi-backhaul cylinder shape heat exchange cavities which are arranged outside the firebox, a wind line device which is communicated with a heat cavity in the heat exchange cavity, and an induced-draft fan which is communicated with a smoke cavity in the heat exchange cavity. As the wall of the heat exchange cavity is provided with a staggered pattern straight cooling plate, the efficient of heat exchange is improved. The induced-draft fan is provided with a wind amount adjusting valve, which can control the heating amount in unit time of the fuel in the firebox. An upper superface and a lower superface of each cylinder shape heat exchange cavity are planes, which prolongs the service life of the hot-air furnace.
Description
The utility model relates to the hot-blast stove technical field, particularly a kind of charcoal indirect hot-blast stove that burns.
At present, hot-blast stove generally all acts as a fuel with coal, makes chimney over-emitting black exhaust, pollution greatly.Existing hot-blast stove roughly is made of body of heater, combustion chamber, heat-exchanger rig, turnover wind apparatus.A kind of " negative pressure adjustable high-efficiency energy-saving hot blast furnace " just disclosed for No. 94227577.2 as Chinese patent.It is provided with spiral flow deflector the air-flow that enters in the heat exchanging chamber is carried out mandatory friction heat exchange in the heat convection chamber, to improve its heat exchange efficiency; The heat exchange efficiency of this kind structure is undesirable.The flue gas flow of this hot-blast stove is unadjustable, makes the caloric value of unit interval not control, and has brought great inconvenience to use.Moreover the upper and lower end face of existing hot-blast stove is the circular cone tubular, because barrel temperature changes greatly, is prone to the weld cracking of cylindrical shell and end face, influences service life.
The purpose of this utility model is: provide a kind of heat exchange efficiency height, simple in structure, life-span long burn charcoal indirect hot-blast stove.
For reaching above-described purpose, the utility model is achieved through the following technical solutions:
A kind of indirect hot-blast stove comprises: be located at the combustion chamber in the body of heater, be provided with many backhauls tubular heat exchanging chamber outside the combustion chamber, the turnover wind apparatus that communicates with hot air cavity in the heat exchanging chamber; The induced-draft fan that communicates with flue gas chamber in the heat exchanging chamber; The heat exchanging chamber wall is provided with the straight shape fin of wrong row's formula.
In the utility model, described induced-draft fan is provided with volume damper.Each tubular heat exchanging chamber end face up and down is the plane.The combustion chamber links to each other by short smoke pipe with second layer high-temperature flue gas interchannel; Temperature measuring equipment is housed in the body of heater, and temperature measuring equipment connects overtemperature alarm and automatic cooling device, and the combustion chamber is made by refractory material.
Advantage of the present utility model is: because the heat exchanging chamber wall is provided with the straight shape fin of wrong row's formula, improved heat exchange efficiency.Induced-draft fan is provided with volume damper, can control the unit interval caloric value of fuel in the combustion chamber, brings great convenience to use.Each tubular heat exchanging chamber end face up and down is the plane, and the plane cylindrical shell can produce deformation, the influence that comes balance to expand with heat and contract with cold, thereby the service life of prolongation hot-blast stove.Hot-blast stove is provided with temperature measuring equipment, overtemperature alarm and automatic cooling device, is easy to temperature in monitoring and the control stove, increases the service life.
Be elaborated the utility model in order more clearly to illustrate below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is a heat exchange process schematic diagram of the present utility model.
As shown in Figure 1: hot-blast stove of the present utility model comprises: by the combustion chamber 1 that refractory material is made, be provided with many backhauls tubular heat exchanging chamber outside the combustion chamber, the heat exchanging chamber wall is provided with the straight shape fin 4 of wrong row's formula, to improve heat exchange efficiency.Hot air cavity in the heat exchanging chamber is connected with air inlet 2 and air outlet 3; Be provided with induced-draft fan 6 on the body of heater top with volume damper 5.Can regulate the burning of control fuel to the flue gas flow of hot-blast stove.Each tubular heat exchanging chamber up and down end face is the plane and expands with heat and contract with cold to the influence of weld with balance, increases the service life.The combustion chamber links to each other by short smoke pipe 7 with second layer high-temperature flue gas interchannel; Temperature thermocouple 8 is housed in the body of heater, and thermocouple connects overtemperature alarm and automatic cooling device.In order to temperature in monitoring and the control stove, prevent that body of heater is overheated, cause hot-blast stove to damage.
Fig. 2 has provided heat exchange process of the present utility model.Air enters first heat exchanging chamber 9 by air inlet, and enters second heat exchanging chamber 10 through first heat exchanging chamber bottom; Hot-air through the two return heat exchange enters internal layer heat exchanging chamber 11, carries out being discharged by air outlet after the sufficient heat exchange with the straight shape heat exchanger fin of mistake row's formula.The flow process of flue gas is as follows: the flue gas in the combustion chamber 1 enters the flue gas interlayer 12 at body of heater middle part by short smoke pipe 7, by the exhaust opening that communicates with the flue gas interlayer, discharges through induced-draft fan.Because hot air cavity and flue gas chamber are staggered, and can effectively utilize the waste heat of flue gas.
