Abstract

The utility model relates to a novel heat-exchanging device which is mainly composed of a gas-burner, a blower, a smoke pipe, a bulkhead, etc.; the smoke pipe and the bulkhead are arranged in a furnace body. The flue gas heat conducts the heat exchange with the cold current which is blown from the blower through the smoke pipe, and an air stack is formed along the bulkhead. The temperature raises through the repeated convolution motion, and heat air is delivered into the room for heating through a hot air port. The heating furnace is used in the south of China or used for household winter heating of the central heating condition, and the heating furnace can also be used in the occasions, such as a hothouse, a greenhouse, a drying chamber, etc. Compared with a coal furnace, the fuel is saved, the thermal efficiency can be reached by more than 70%, and the environment pollution is reduced. The utility model develops a new way for the exploration and utilization of the combustion gas energy source.

Description

Bulkhead convolution type gas hot-air heating farnace

The utility model relates to the combustion gas heat-exchange device, and particularly a kind of it can be used for family with the dividing plate swinging air heating stove as fuel gas source such as coal gas, natural gas, liquefied gas, unit heating, occasions such as greenhouse greenhouse and oven dry.

At present, China lacks the unit and the family of central heating condition, and warming is except still generally adopting common coal stove or " native heating installation ", occurred coal-fired hot-blast stove again, utilized air heating, it is to utilize fire coal to make thermal source, with the gas in ventilation duct heating, carry out heat exchange.Make fuel with coal, not only not fully comprehensive utilization, and also the flue dust after the burning can cause serious pollution to environment.

In order to reduce the Application and Development of environmental pollution and new forms of energy, the purpose of this utility model provides a kind of dividing plate swinging air heating stove that utilizes combustion gas as thermal source.

The purpose of this utility model is realized by following proposal.

The heat that fuel gas buring discharged of body of heater passes in the densely covered smoke pipe uphill process, is risen by cold airflow revolution around smoke pipe that air blast blows into, and carries out heat exchange, becomes hot blast and is displaced into indoor heating.

Fig. 3, A-A place profile

Now in conjunction with the accompanying drawings and embodiments the utility model is elaborated.

As shown in Figure 1, the utility model is mainly by base 10 with hot-air mouth 6 is arranged, and outer burnt gas valve 1, the air blasts 2 of burner 9, smoke pipe 8, dividing plate 7 and stove in the upper furnace body 11 of floss hole 5 are formed.The inwall of body of heater is filled with heat-insulation layer 3, to reduce scattering and disappearing of heat, body of heater can be designed to square column type (as present embodiment shown in Figure 2) and also can be designed to cylindrically, and gas burner 9 is an atmospheric burner, is applicable source of the gas of different nature as long as change indivedual parts in addition.Its air inlet valve 1 is a switch, and adjustable fuel gas amount again is with the temperature of control heating hot blast.

The material of smoke pipe 8 is generally selected the high copper tube of thermal conductivity factor for use, to improve heat exchanger effectiveness, dwindles the heat exchange space.Smoke pipe quantity is generally elected as between 10～20, and horizontal layout is by cross arrangement (as shown in Figure 3), and smoke pipe is two ends shut on every side up and down, and the middle wind chamber that forms promptly only allows fuel gas calorie to enter smoke pipe, carries out heat exchange with cold airflow in the wind chamber.In order to improve heat exchange effect, prolong heat exchanger time, in smoke pipe, be provided with disorderly smoked sheet 12, the snakelike strip of disorderly smoked sheet for being made by thin metal blank in smoke pipe, makes the full of twists and turns rising of hot flue gas, to reach the purpose of fully carrying out heat exchange.

Shut along smoke pipe 8 some one ends that are being interspersed, the dividing plate 7 that an end is uncovered, revolution air channel (as shown in Figure 1), its objective is to prolong the air-flow flow process, increase heat-exchange time, improve the thermal efficiency, separator material generally adopts general steel plate, and quantity is the 4-6 piece.

Blower fan 2 adopts mini fan, blast, air quantity should not be excessive.

Top cover 4 adopts ironcasting, and cost is low, and is durable in use.

Base 10 is a square column type or cylindrical, also is provided with around the base for the required air hole of burning.

This heat supply stove uses; Open the valve 1 that connects source of the gas earlier, ignition combustion device 9, fuel gas calorie rise by smoke pipe, and by the air channel of cold wind by being formed by dividing plate 7 that blower fan 2 blows into, revolution is risen and absorbed the heat that smoke pipe distributes repeatedly, becomes thermal current, is discharged into indoor from hot-air mouth.Hot flue gas passes smoke pipe and discharges through the chimney that floss hole 5 connects.

This heat supply stove can be used for lacking the family of central heating condition, and unit and China's south resident's warming also can be used for greenhouse, greenhouse, occasions such as drying chamber.Fuel gas source can adopt artificial coal gas, natural gas, liquefied petroleum gas etc.It is a kind of combustion gas new forms of energy that utilize, and the thermal efficiency can reach more than 70%, and can reduce the novel heating installation of environmental pollution.
