Summary of the invention
In order to address the above problem, the utility model provides a kind of combined type waste heat recovery heater, and a kind of more practical, more economical, more environmental protection, waste heat recovery heater that the scope of application is wider are provided.
The utility model relates to a kind of composite and multi-purpose flue gas waste heat-recovering equipment, utilizes the fume afterheat can be simultaneously or preheated burning air and heating demineralized water etc. separately.
A kind of combined type waste heat recovery heater that the utility model provides, it contains at least one group of waste heat recovery heater, described waste heat recovery heater comprises: concentric bilayer heat pipe (1), dividing plate (2), lower union (3), upper union (4), upper header (5), lower collector pipe (6), wherein:
Described upper union, concentric bilayer heat pipe and lower union connect successively, and the described dividing plate of described dividing plate is divided into sky crosswind road and fume side flue to heat exchanger, make described air not be communicated with described flue gas;
Described upper union is positioned at described upper header, and described lower union is positioned at described lower collector pipe;
Described concentric bilayer heat pipe is divided into inner and outer tubes.
Preferably, fill working media between the hollow heat pipe inner and outer pipes of the annular concentric of described concentric bilayer heat pipe and be evacuated, the outer tube Lower Half is exposed in flue gas.
Preferably, described waste heat recovery heater is that a plurality of parallel waies link.
The combined type waste heat recovery heater that the utility model provides adopts the high-performance heat transfer components heat pipe to do basic heat exchange element, and install the fin reinforcing heat exchange additional in fume side and air side, greatly improve heat exchange efficiency, adopt heat pipe to do the biography heat transfer boundary condition, the heating surface wall surface temperature is controlled, fundamentally avoid dew point corrosion, greatly improved the Whole Equipment life-span.The utility model device structure is reasonable, and advanced technology can heat separately hot blast or heat separately demineralized water, and hot blast and demineralized water are heated in also utilization capable of being combined simultaneously.
Description of drawings
The structural representation of the combined type waste heat recovery heater that Fig. 1 provides for the utility model;
The operation principle schematic diagram of the combined type waste heat recovery heater that Fig. 2 provides for the utility model.
The specific embodiment
The combined type waste heat recovery heater that the utility model provides, it comprises the waste heat recovery heater of one or more parallel connections, and wherein the waste heat recovery heater comprises: concentric bilayer heat pipe (1), dividing plate (2), lower union (3), upper union (4), upper header (5), lower collector pipe (6); Upper union, concentric bilayer heat pipe and lower union connect successively, and dividing plate makes described upper union not be communicated with being connected of lower union with concentric bilayer heat pipe, concentric bilayer heat pipe; Upper union is positioned at described upper header, and described lower union is positioned at described lower collector pipe; The concentric bilayer heat pipe is divided into inner and outer tubes, fills working media between the hollow heat pipe inner and outer pipes of the annular concentric of concentric bilayer heat pipe and is evacuated, and the outer tube Lower Half is exposed in flue gas.
During work, high-temperature flue gas is by patent equipment Lower Half smoke box, heat is passed to heat-pipe working medium, the heat-pipe working medium vaporization, heat is passed to the demineralized water of heat pipe inner tube and the air of the heat pipe first half, cold demineralized water enters the heat pipe inner tube by lower collector pipe 6 and union, absorb the heat temperature rising that working medium is transmitted, and discharge by upper header 5, cold air is by its upper side air duct access arrangement, absorb the heat temperature rising discharge that heat-pipe working medium transmits, the amount that passes into cold air and cold demineralized water can be passed through the automatic valve Automatic Balance Regulation.
In sum, the utility model provides a kind of combined type waste heat recovery heater to take full advantage of the heat of flue gas in flue, reduced the waste of the energy, amount of heat that simultaneously can preheated air can be regulated by the air capacity of passing through, demineralized water absorption heat can pass into the desalination water yield by control and regulate, and also can automatically regulate by balance Control Scheme.The combined type waste heat recovery heater that the utility model provides adopts the high-performance heat transfer components heat pipe to do basic heat exchange element, and install the fin reinforcing heat exchange additional in fume side and air side, greatly improve heat exchange efficiency, adopt heat pipe to do the biography heat transfer boundary condition, the heating surface wall surface temperature is controlled, fundamentally avoid dew point corrosion, greatly improved the Whole Equipment life-span.The utility model device structure is reasonable, and advanced technology can heat separately hot blast or heat separately demineralized water, and hot blast and demineralized water are heated in also utilization capable of being combined simultaneously.The whole heat exchange efficiency of this device can reach more than 35%, successful, and convenient quality control, cost-effectively simple in structure is cheap and can greatly lower the energy loss, is more suitable for large-scale production and business and uses; The scope of application is wide especially, therefore easily applies, and can have a tremendous social and economic benefits in the short period of time.
