The heat exchanger of the smoke and hot water boiler is characterized in that the box body is divided into a heat exchange box body and a smoke box body, the metal separating plate fixed through bolts is installed between the heat exchange box body and the smoke box body, an evaporation section of each heat pipe is of a finned pipe structure, and condensation sections of the heat pipes are sleeved with water jackets which are mutually communicated. The heat exchanger of the smoke and hot water boiler has the advantages of being scientific and reasonable in structural design, capable of fully using waste heat of the smoke, improving the thermal efficiency, prolonging the service life, convenient to repair and high in innovation performance.
Description
Technical field
The invention belongs to boiler HVAC field, relate to a kind of heat-transfer equipment, particularly a kind of fume hot-water boiler heat-exchanger.
Background technology
Heat exchanger is a kind of energy-saving equipment that between material, heat transmits of realizing between two or more fluid of different temperatures, can make heat pass to by higher fluid the fluid that temperature is lower, make fluid temperature (F.T.) reach flow process set quota, to meet the needs of process conditions.Meanwhile, heat exchanger is also one of capital equipment improving energy utilization rate, in chemical industry, oil, power, food and other many industrial circles, occupies critical role.Heat exchange of heat pipe is domestic development a kind of heat-exchange device faster in recent years, heat pipe is as the heat transfer element of heat exchanger, its one end is evaporator section (bringing-up section), and the other end is condensation segment (cooling section), and according to application, needing can be two sections of intermediate arrangement adiabatic section.The vaporization of liquid evaporation when one end of heat pipe is heated in Mao Renxin, steam flows to the other end and emits heat and condense into liquid under small pressure reduction, and liquid flows back to evaporator section along porous material by the effect of capillary force again.So circulation oneself, heat is reached separately-is held by one end of heat pipe, takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and phase change medium, through heat pipe, the heat of thermal objects is delivered to rapidly outside thermal source, has advantages of that simple structure, efficiency are high.
Existing heat exchange of heat pipe consists of casing, heat pipe and metal partion (metp), on the inwall of casing, be welded with metal partion (metp), the smoke box that this metal partion (metp) is bottom by the interior separation of casing and be positioned at the heat exchange box on smoke box top, on the casing of smoke box both sides, be respectively arranged with into mouth and outlet flue, on the casing of heat exchange box both sides, be respectively arranged with water inlet and delivery port, the heat pipe of longitudinal setting is installed on the plate face of metal partion (metp).Existing heat exchange of heat pipe structure is comparatively single, and also there are the following problems: 1. casing is integral type structure, and the mounting means that welds in casing of metal partion (metp), is unfavorable for the maintenance of heat exchanger; 2. the evaporator section of heat pipe (bringing-up section) is polished rod structure, and the efficiency of heating surface is lower; 3. the heat exchange box of heat exchanger is partly that the condensation segment (cooling section) of heat pipe directly contacts with water, easily causes adhering to and the corrosion of heat pipe of incrustation scale on heat pipe, has shortened the service life of heat pipe and whole heat exchanger.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of design science rationally, make full use of fume afterheat, improve the thermal efficiency, increase the service life, be convenient to the fume hot-water boiler heat-exchanger of maintenance.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of fume hot-water boiler heat-exchanger, comprise casing, heat pipe and metal partion (metp), described heat pipe is installed in installing hole made on metal partion (metp), it is characterized in that: described casing is divided into heat exchange casing and smoke box casing two parts, between heat exchange casing and smoke box casing, the metal partion (metp) being bolted is installed, the evaporator section of described heat pipe is fin tube structure, and the condensation segment of described heat pipe is set with the water jacket being interconnected outward.
And, between described metal partion (metp) and heat exchange casing and between metal partion (metp) and smoke box casing, be respectively arranged with sealing gasket.
And described sealing gasket is the sealing gasket that heat resistant rubber is made.
Advantage of the present invention and good effect are:
1. this fume hot-water boiler heat-exchanger, by two parts casing that traditional integrated box is designed to be connected and fixed by bolt, and, the metal partion (metp) being bolted is set between two parts casing, facilitated the maintenance of heat pipe.And by the evaporator section of heat pipe is designed to fin tube structure, strengthened the contact area with flue gas, improve heat exchange efficiency; To on the condensation segment of heat pipe, install water jacket additional, this water jacket not only can help hot pipe cooling, and, also avoided adhering to incrustation scale on the outer wall of heat pipe, shorten the service life of heat pipe.
2. this fume hot-water boiler heat-exchanger, by between metal partion (metp) and heat exchange casing and between metal partion (metp) and smoke box casing, sealing gasket being set, has guaranteed the sealing of heat exchange casing and smoke box casing, avoids the leakage of cold and hot medium (water, flue gas).
3. scientific structure design of the present invention is reasonable, and there is the fume afterheat of making full use of, improve the thermal efficiency, increase the service life, be convenient to maintenance, be a kind of fume hot-water boiler heat-exchanger with higher innovation.
