Abstract
The utility model discloses a full soldering board type overfall heat net heater, and belongs to heat exchanging equipment, in particular to a plate type heat exchanger, the heat net heater adopts round heat exchanging plates which are welded into a plate bundle, a plurality of groups of plate bundles are welded into a heat exchange core body and are installed in a cylindrical shell, since plate bundle form of surrounding group welding is adopted, sealing pads are cancelled, and the heat resistance and pressure resistance performances are better than detachable type heat exchangers. The plates are modular structure, and flow modes and flow passage size can be changed according to different technical demands. The investment is small, the cost is low, and the defects of original full welding type plate shell type heat exchangers are overcome. The heater is a highly-efficiency heat exchanging device, and is applicable to gas to liquid and liquid to liquid heat exchange occasions with high heat transmission efficiency, compact structure and low pressure reduction.
Description
Technical field
The utility model belongs to heat-exchange apparatus, particularly plate type heat exchanger.
Background technology
In carbonated drink shell-and-tube heat exchangers for district heating application widely at present and steam power plant and the city central heating system, it has characteristics such as can bearing high temperature, high pressure, no leakage, but low, the easy fouling of heat exchange efficiency, weight per volume are big, the loaded down with trivial details maintenance difficult of production process, manufacturing cost height, investment are big etc.And plate type heat exchanger has very high heat transfer coefficient, general 4500～6500W/m
2.K, have characteristics such as compact conformation, the occupation of land space is little, dismounting is easy to maintenance simultaneously again.But because the restriction of structure and rubber gasket be to the limitation of temperature, so it is more suitable for using under the operating mode of low pressure, low temperature.HTHP in industries such as thermoelectricity, chemical industry, smelting, not competent under the operating mode that prevents to reveal.
Chinese patent 01265997.5 discloses a kind of all welded type lamella heat exchanger, made up certain effect that the advantage of preceding two kinds of heat exchangers obtains preferably, but, need repeatedly final molding of continuous punching press because its elongated battened construction that adopts adopts the hydraulic press punching press.Meet the cutter place and occur fold, crackle easily, there is cumulative departure in length direction.Weld seam system between two thin plates adopts automatic argon arc welder, automatically location, welding automatically.Wherein the unfitness of butt joint of two thin plates and the amount of dehiscing between plate are all wanted strict control, otherwise will cause weld defect or cause leak source.These all need special equipment to solve, and output investment ratio is bigger.So, need specialization, production in enormous quantities just can reduce cost.
The utility model content
For all welded type lamella heat exchanger manufacture difficulty that overcomes existing use rectangle heat exchange plate big deficiency, the purpose of this utility model provides the board-like turbulent flow heat exchangers for district heating of a kind of full weldering, should the board-like turbulent flow heat exchangers for district heating of full weldering pressure-bearing height, high temperature resistant but also be easy to make not only, the low utilization of cost promoted.
The technical scheme that its technical problem that solves the utility model adopts is: the board-like turbulent flow heat exchangers for district heating of a kind of full weldering, comprise shell, heat exchange core body, it is characterized in that: described heat exchange core body becomes undulatory circular heat exchange plate according to crest the mode of crest to be combined in the periphery welding by two to form weld seam between plate and become the plate bundle, form runner between plate between two plates, many group plate bundles are combined into heat exchange core body according to trough to the mode of trough, import and export the adjacent two plate bundles welding of periphery at the heating agent of each plate and form weld seam between pipe, two plate interfasciculars are runner between pipe, heat exchange core body is installed in the columniform shell, shell is provided with runner import between pipe, runner exit between pipe is installed between the plate of outer casing end between runner import and plate the heating agent on the runner exit and heat exchange core body and imports and exports and join.
The ripple of described undulatory circular heat exchange plate is circular arc, rectangle or half hexagon.The board-like turbulent flow heat exchangers for district heating of the full weldering of the utility model has following advantage:
1, the utility model adopts unique all-welded structure and pressure vessel protectiveness shell, makes it have that the shell-and-tube heat exchangers for district heating is high temperature resistant, the high voltage performance characteristics.
2, the utility model adopts unique disk and thin plate design, has overcome the shortcoming of the microscler battened construction of existing all welded type casing-structure heat-exchanger, only needs a mold, and cost is low, and can a whole moulding of punching press.Stressed evenly because of it, the balanced stretching guarantees that it has good compression capability.
3, the circular heat exchange plate welding of identical two dark ripples, big water channel design forms the plate bundle, adopt the heat transfer theory of plate type heat exchanger, formed runner between the plate of similar plate type heat exchanger in the plate interfascicular, again by runner between plate Shu Zucheng pipe, the cold fluid and hot fluid partition flows, and realizes complete countercurrent flow.Heat transfer efficiency than traditional high 3-8 of shell-and-tube heat exchangers for district heating doubly.Its compact conformation, the heat transfer area of unit volume are 1.2 times of shell-and-tube, thereby equipment volume is reduced, and weight saving only is 1/4 of identical heat exchange area shell-and-tube heat exchangers for district heating.
4, with a kind of fluid in the shell-and-tube heat exchangers for district heating when Reynolds number is 4000～6000, just can reach turbulence state, and in full weldering plate type heat exchanger when Reynolds number is 100～300, just can reach turbulence state.
5, plate is after staggered welding all around, and owing to expanding with heat and contract with cold phenomenon, the plate internal stress discharges in running, and the surperficial dirt of plate is split away off automatically.Usually dirtiness resistance only is 1/5～1/4 of a shell-and-tube heat exchangers for district heating dirtiness resistance.
The template reasonable in design of the board-like heat exchangers for district heating of the disclosed full weldering of the utility model in a word, make heat transfer reasonable with fluid resistance characteristic coupling, so the heat transfer efficiency height, pressure drop is low, combination property is preferable, has eliminated the dead band phenomenon that shell-and-tube heat exchangers for district heating and detachable board-like heat exchanger exist.Adopt the plate bundle form of peripheral assembly welding, cancelled gasket seal, so heat-resisting, withstand voltage properties is better than detachable board-like heat exchanger.Plate is a modular construction, can change the size of flow process form and flow area according to different technological requirements.And small investment, cost is low, has overcome the deficiency of original all welded type lamella heat exchanger.Be a kind of high-efficiency heat exchanger equipment, be applicable to solution-air and liquid-liquid heat exchange occasion use that heat transfer efficiency height, compact conformation and pressure drop are little.
