Description
Technical field
The present invention relates to the heat recovery systems in a kind of drying room for tentering boarding machine.
Background technique
Framing shaping machine is a kind of textile machine for the dehydration of textile fabric, drying, baking, arrangement, thermal finalization, tentering
It needs to heat using combustion of natural gas in forming machine, existing framing shaping machine generallys use direct gas heating system, burns
Head is to mix fresh air and natural gas in proportion to spray into baking oven burning in normal use process, on the one hand, due to combustion
The flame that makes a fire is difficult to control, and combustion of natural gas head heat of nozzle cap in burning is not easy to pump, and is easy product heap, framing shaping machine dries
Temperature distribution is non-uniform in case, and the local local temperature close to combustion chamber is excessively high, influences processing effect and product quality, separately
The incomplete combustion of one side natural gas also results in the waste of combustion gas.
Summary of the invention
The object of the invention seeks to provide a kind of Temperature Distribution that can make in framing shaping machine baking oven more evenly, improves burning
Efficiency reduces the heat recovery system in the drying room for tentering boarding machine of combustion gas waste.
The present invention is achieved through the following technical solutions:
A kind of heat recovery system in drying room for tentering boarding machine, including cylindrical combustion room, gas inlet pipe, combustion gas blower,
Gas mixing chamber, combustion head, air hose, air valve, air blower, combustion gas mixing plate；
Wherein the gas inlet pipe connects combustion gas fan inlet, and combustion gas fan outlet connects gas mixing chamber, and combustion gas is mixed
It closes room and connects combustion head；
The air hose includes three sections, is air inlet section, bringing-up section, air outlet section, air blower connection air inlet section, air inlet respectively
Air valve is provided in section, control enters the cold air amount of air hose, and bringing-up section is the helix tube being looped around outside cylindrical combustion room
Section, using the high temperature of combustion chamber come the air in heating coil pipeline section, air outlet section is connected to gas mixing chamber, by heating
Air is introduced in gas mixing chamber, with combustion gas mixing；
Optimization, the air inlet section of the air hose, bringing-up section, the position of air outlet section from low to high, can use heat in this way
The light reason of air makes the air of heating enter gas mixing chamber in a manner of Natural Circulation；
Optimization, two blocks of mutually perpendicular combustion gas mixing plates, the combustion gas mixing plate are provided in the gas mixing chamber
On be evenly arranged with multiple circular holes, combustion gas and the hot-air of gas mixing chamber are entered from combustion gas blower and air hose, it is mixed in combustion gas
The separation for passing through combustion gas mixing plate in room is closed, enters combustion head after evenly mixing；
Optionally, the cylinder straight tube for surrounding combustion chamber can also be used in the bringing-up section of air hose.
The beneficial effects of the present invention are: combustion is sent to after pigtail heating of the cold air in air hose outside combustion chamber
In gas mixing chamber with combustion gas mixing, on the one hand can improve in drying chamber non-uniform temperature distribution, on the other hand, by improve into
The air themperature for entering combustion head keeps burning more complete, improves the thermal efficiency, and the utilization rate of the energy reaches maximization, reduces the energy
Loss, alleviates production cost, improves the competitiveness of user.
Detailed description of the invention:
Attached drawing 1 is overall structure signal of the invention；
Attached drawing 2 is the schematic diagram of gas mixing chamber；
Attached drawing 3 is the schematic diagram of combustion gas mixing plate；
Attached drawing 4 is optional embodiment schematic diagram；
In figure, gas inlet pipe 1, combustion gas blower 2, gas mixing chamber 3, combustion head 4, air blower 5, air hose 6, air
Valve 7, combustion chamber 8,31 are the fuel gas inlets of gas mixing chamber, and 32 be the hot-air inlets of gas mixing chamber, and 33 be combustion gas mixing
Plate；
Specific embodiment:
The present invention will be further described with reference to the accompanying drawings and detailed description:
It is as shown in Figure 1 to Figure 3:
Gas inlet pipe 1 connects 2 import of combustion gas blower, the outlet of combustion gas blower 2 connection gas mixing chamber 3, gas mixing chamber 3
Combustion head 4 is connected, combustion gas leads into gas mixing chamber 3 by combustion gas blower 2, in gas mixing chamber 3 after mixing air, into
Enter the burning of combustion head 4；
Air hose 6 includes three sections, is air inlet section, bringing-up section, air outlet section, the connection air hose 6 of air blower 5, air respectively
Air valve 7 is provided in 6 air inlet section of pipe, control enters the cold air amount of air hose, there cannot be mixing too in combustion gas in igniting
More air, this will lead to ignition difficulties, and when normal operation, the air needed is more, it is therefore desirable to which air valve controls in combustion gas
Air capacity, bringing-up section is the pigtail being looped around outside combustion chamber, using the high temperature of combustion chamber come the sky in heating coil pipeline section
Gas, air outlet section are connected to gas mixing chamber, the air by heating are introduced in gas mixing chamber, with combustion gas mixing；
The air inlet section of air hose 6, bringing-up section, the position of air outlet section from low to high, can use the light original of hot-air in this way
Cause makes the air of heating enter gas mixing chamber in a manner of Natural Circulation；
It is provided with two blocks of mutually perpendicular combustion gas mixing plates 33 in gas mixing chamber, is evenly arranged on combustion gas mixing plate 33
Multiple circular holes enter combustion gas and the hot-air of gas mixing chamber from combustion gas blower and air hose, by combustion in gas mixing chamber
The separation of gas mixed plate enters combustion head after evenly mixing；
In Fig. 4, the bringing-up section of air hose is different from the pigtail of a upper scheme, straight using the cylinder for surrounding combustion chamber
Pipe, cold air enter gas mixing chamber after heating in cylinder straight tube.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
