Abstract
The utility model relates to a dropwise condensation type heater for a heating network. The heater comprises a shell, channels arranged at two ends of the shell, a steam inlet formed on the shell, a heat exchange pipe arranged in the shell, a water inlet formed on the lower side of each channel and a water outlet formed on the upper side of each channel, wherein two ends of the shell are respectively provided with a cylindrical tube plate, tube holes are formed in each tube plate, and the tube holes corresponding to the two tube plates are in sealed communication through the heat exchange pipe; the water inlet and the water outlet are communicated through the tube plates and the heat exchange tube; and a plurality of tube holes form an inverted triangular or V-shaped tube hole assembly, and a plurality of inverted triangular or V-shaped tube hole assembles are arranged on the tube plates. According to the dropwise condensation type heater for the heating network, steam can circulate more smoothly and more naturally along the shell side, and can perform heat exchange more directly and more quickly with water in the heat exchange pipe; the adopted nickel-based implanted heat exchange pipe has high surface hardness, so that the service life of the equipment is prolonged; and the steam forms dropwise condensation on the surface of the heat exchange pipe by virtue of the nickel-based implanted pipe, so that high efficiency heat exchange between steam and water can be realized.
Description
Technical field
The utility model relates to a kind of heat exchangers for district heating, particularly a kind of dropwise condensation formula heat exchangers for district heating.
Background technology
At present, heat exchangers for district heating stringing commonly used conventional stringing mode commonly used, steam channel is generally level or vertical the layout, and the forcibly changing normal flow direction got into tube bank along passage after steam got into shell-side, caused heat exchange efficiency low and vibration is bigger; Secondly steam and water carry out heat exchange through heat exchanger tube in the conventional heat exchangers for district heating, and steam forms water membrane in the heat exchanger tube surface condensation, as clothes heat exchanger tube is wrapped in wherein; Thereby diabatic process is steam---moisture film---heat exchanger tube, and the heat exchange effect is relatively poor, and the heat exchange area of heat exchangers for district heating needs is bigger like this; The weightening finish of equipment overall weight, appearance and size is big, and the occupation of land space is big; Thereby overall cost is higher, and efficient is low, and equipment life is short.
Summary of the invention
The utility model provides a kind of steam that makes more smooth and easy, natural in the shell-side circulation in order to overcome the deficiency of above technology, and efficient improves the dropwise condensation formula heat exchangers for district heating that increase service life.
The technical scheme that its technical problem that overcomes the utility model adopts is:
This dropwise condensation formula heat exchangers for district heating; Comprise housing, be arranged at the housing two ends bobbin carriage, be arranged at steam inlet on the housing, be arranged on the heat exchanger tube in the housing and be arranged at the water inlet of bobbin carriage below and be arranged at the delivery port of bobbin carriage top; The housing two ends are separately installed with columniform tube sheet; Tube sheet is provided with pore, and the corresponding pore of two tube sheets seals connection mutually by a heat exchanger tube, and water inlet and delivery port are connected through tube sheet and heat exchanger tube; Plurality of tube holes is formed the pore group of del or V-arrangement, and several pore group arranged that are del or V-arrangement are on tube sheet.
Above-mentioned heat exchange tube outer wall is provided with nickel-base seeping layer.
Above-mentioned nickel-base seeping layer thickness is 0.012mm-0.015mm.
The beneficial effect of the utility model is: the dropwise condensation formula heat exchangers for district heating of the utility model can make steam more smooth and easy, natural in the shell-side circulation, and is more direct with hydrothermal exchange in the heat exchanger tube, rapidly; And adopt the nickel-base seeping layer heat exchanger tube; Case hardness is high, and increase equipment life, and the nickel-base seeping layer pipe makes steam form dropwise condensation on the heat exchanger tube surface; Reduced one deck heat transmission resistance " moisture film ", realized because of steam and water high efficient heat exchanging.The dropwise condensation formula heat exchangers for district heating of the utility model makes required heat exchange area reduce, compact conformation, and cost is low, and the occupation of land space is little.

Among the figure, 1. bobbin carriage 2. housings 3. delivery ports 4. water inlets 5. heat exchanger tubes 6. tube sheets 7. steam inlets 8. pore groups.
The specific embodiment
Further specify below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.
This dropwise condensation formula heat exchangers for district heating; Comprise housing 2, be arranged at housing 2 two ends bobbin carriage 1, be arranged at steam inlet 7 on the housing 2, be arranged on the heat exchanger tube 5 in the housing 2 and be arranged at the water inlet 4 of bobbin carriage 1 below and be arranged at the delivery port 3 of bobbin carriage 1 top; Housing 2 two ends are separately installed with columniform tube sheet 6; Tube sheet 6 is provided with pore, and two tube sheets, 6 corresponding pores seal connection mutually by a heat exchanger tube 5, and water inlet 4 is connected through tube sheet 6 and heat exchanger tube 5 with delivery port 3; It is characterized in that: plurality of tube holes is formed the pore group 8 of del or V-arrangement, and several pore group 8 arranged that are del or V-arrangement are on tube sheet 6.After steam gets into housing 2 through steam inlet 7; Get into along the branching shape steam channel in the tube bank of heat exchanger tube 5 compositions,, make steam directly contact more rapidly with heat exchanger tube 5 because set of heat exchange tubes is the tree-shaped stringing of bionical attitude; Directly carry out heat exchange with the water in the heat exchanger tube 5 through the heat exchange tube wall; Improve heat-transfer effect, and significantly reduced the resistance that steam flows, reduce the impact of steam tube bank.
Above-mentioned heat exchanger tube 5 pipe outer walls are provided with nickel-base seeping layer, and said nickel-base seeping layer thickness is 0.012mm-0.015mm.Make heat exchanger tube 5 case hardnesses improve, erosion resistance makes steam form dropwise condensation in the above through heat exchanger tube 5 surfaces of oozing nickel; Rather than become the moisture film shape to condense, and the tree-shaped stringing mode of the bionical attitude of set of heat exchange tubes makes that also the water that condenses can flow into lower housing portion along steam channel; Make heat exchanger tube 5 be in naked state all the time, steam and heat exchanger tube 5 are in direct contact heat-exchanging all the time, have improved heat transfer coefficient greatly; Make the required heat exchange area of equipment reduce, compact conformation, cost reduces; Reducing and the raising of heat exchanger tube 5 case hardnesses of vibration makes improve greatly equipment life.
