Abstract
A heat exchanger in a half-direct combustion type vehicle paint baking booth is provided with a frame, a cylindrical combustion chamber and a main radiator pipe frontal chamber, a main radiator pipe back chamber, a right main radiator pipe and a left main radiator pipe that are communicated with the cylindrical combustion chamber, and is characterized in that the left main radiator pipe and the right main radiator pipe is provided with hot air overflow outlets respectively in the pipe walls; flame filter screens are arranged above the hot air overflow outlets; the left main radiator pipe and the right main radiator pipe are provided with hot blast cycle flame-off devices inside. The device has the advantages of simple structure, high energy utilization rate, high thermal efficiency, safety and reliability.
Description
The utility model relates to a kind of thermal energy conversion device, particularly a kind of heat exchanger that is used for the half direct combustion-type in baking finish for car room.
What existing baking finish for car room adopted is indirect heat exchanger, as Chinese patent ZL97225737.3 combined padding and drying system heat exchanger, it is the heat exchanger of a kind of heat radiation type, fuel combustion type, produce heat by oil inflame, the radiating tube of the many rows heat radiation type by being located at the combustion chamber upside dispels the heat, thereby finishes heat exchange.This heat exchanger is owing to adopt heat radiation type to carry out the heat exchange of indirect type, so its thermal efficiency is low, high thermal efficiency can only reach about 80%, and along with the continuous rising of temperature in the combined padding and drying system, the thermal efficiency also can progressively reduce; In addition because main radiating tube cup top is provided with smoke evacuation chamber and chimney, the a large amount of heat that produces during burning also can be along with chimney is discharged outside the combined padding and drying system, cause energy waste, when the temperature requirement in the combined padding and drying system reaches 80 degree when above, the degree difficulty that heats up to the high temperature direction is also quite big.This structure also is only applicable to the mode of fuel oil, and when work knot charcoal phenomenon is also quite serious.Along with the variation of economic structure, high-efficiency environment friendly combustion gas mode will generally be adopted.At the characteristics of combustion gas, be badly in need of a kind of high efficiency of suitable combustion gas, low-loss combined padding and drying system heat exchanger.
The purpose of this utility model be to provide a kind of simple in structure, the thermal efficiency is high, be applicable to half direct combustion-type combined padding and drying system heat exchanger of gas type.
Technical solution of the present utility model is, be provided with support, cannular combustion chamber is housed on the support, and combustion chamber top is respectively equipped with chamber behind the main radiating tube cup of intercommunication, the main radiating tube, the main radiating tube of right side master's radiating tube and left side, and main radiating tube cup communicates with the combustion chamber; The front side of combustion chamber is connected to the burner interface that communicates, the top of burner interface is provided with the internal pressure safety device that communicates with main radiating tube cup, it is characterized in that: about have the hot-air overfall on the tube wall of main radiating tube, flame filter net about the top of its hot-air overfall is provided with and is fixed on the main radiating tube tube wall, and about be respectively equipped with the hot air circulation device that reduces internal heat in the pipe of main radiating tube.
The utility model compared with prior art, the combustion chamber is big, the thermal current flow process is reasonable, and is simple in structure, good effect of heat exchange, thermal efficiency height, loss is low, the energy utilization rate height, be a kind of be specially adapted to combustion gas, the half direct heat exchanger of combustion-type.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The utility model is provided with a support 9, cannular combustion chamber 1 is housed on the support 9,1 top, combustion chamber is respectively equipped with chamber 8 behind the main radiating tube cup 4 of intercommunication, the main radiating tube, the main radiating tube 11 of right side master's radiating tube 10 and left side, and chamber 8 communicates with combustion chamber 1 respectively behind main radiating tube cup 4 and the main radiating tube; The front side of combustion chamber 1 is connected to the burner interface 2 that communicates, and the top of burner interface 2 is provided with the internal pressure safety device 3 that communicates with main radiating tube cup 4.Burner interface 2 can external gas type burner.Have hot-air overfall 7 on the tube wall of main radiating tube 10,11 about it, the top of hot-air overfall 7 is covered with flame filter net 6, and flame filter net 6 is fixed on the tube wall of the main radiating tube 10 in left side or right side master's radiating tube 11 by screw.About be respectively equipped with the hot air circulation device 5 that reduces internal heat in the pipe of main radiating tube 10,11.
During work, burner is by burner interface 2 jet flames in the combustion chamber, the heat that burning is produced, cause combustion chamber 1 interior air themperature to raise rapidly, expand, make air flow to left and right sides radiating tube 10 through main radiating tube cup 4,11 and main radiating tube after chamber 8, except that carrying out normal thermal energy exchange, hot-air in the radiating tube since temperature raise expand produce thermal pressure make hot-air through after 5 filtrations of flame filter net directly from about main radiating tube 10,11 overfall 7 overflows, thereby enter in the combined padding and drying system room body with the air-supply air-flow, to reach the purpose that is rapidly heated.
The utility model is owing to directly have the hot-air overfall on radiating tube, so the heat energy part in the radiating tube is carried out heat exchange by the radiating tube tube wall heat that sheds, another part is directly overflowed by the hot-air overfall after the device that reduces internal heat reduces internal heat in radiating tube, thereby finishes heat exchange.So the utility model is a kind of heat exchanger that is applicable to combustion gas of half direct combustion-type.
