Abstract
The utility model discloses a shell-tube type heat-exchanger for sewage source heat pump. The utility model consists of a metal housing and recuperator tubes. The recuperator tubes are arranged in the metal housing; one side of the housing is provided with an inlet and an outlet connected with the recuperator tubes in the housing, the top part of the housing is provided with a sewage inlet a sewage outlet and the side wall of the housing is provided with two cleaning holes; the cleaning holes are provided with hole covers, obturating rings are arranged between the hole covers and the cleaning holes. When a plurality of foreign matter or impurities are entwined on the recuperator tubes, a customer can flush the impurities on the recuperator tubes directly with high pressure water or other modes or maintain the recuperator tubes. As the diameter of the housing of the heat-exchanger for heat pump is larger, the recuperator tubes are arranged sparsely and the sewage can flow smoothly, the pressure in the housing is not high, the requirement on the housing welding and sealing is not high and the structure is relatively simple; meanwhile, the big flow of circulatory sewage can provide more heat, thereby ensuring the heat exchange effect of the heat-exchanger. The heat-exchanger is an integrated structure and mounting of the heat-exchanger is more convenient.
Description
Technical field
The utility model relates to a kind of heat exchanger, refers to a kind of sewage source heat pump shell and tube exchanger especially.
Background technology
The sewage source heat pump type air corditioning system is a kind of pump type heat monoblock type water-air aircondition that carries out the refrigerating/heating circulation with sewage as thermal source.It is to extract energy from sewage treatment plant's secondary, three grades of water outlets, utilizes heat pump techniques to make hot water in the winter time and heats to building, makes cold water to building cooling with sewage as the heat extraction source in summer, and it is a kind of form that sewage recycling utilizes.
The shell and tube exchanger that the present invention relates to is the important composition parts in the sewage source heat pump type air corditioning system.Winter it as evaporimeter, summer as carrying out exchange heat between condenser and the sewage.Because shell and tube exchanger is immersed in the sewage, foreign matter in the sewage and impurity usually are wrapped on the heat exchanger, influence the rate of heat exchange of heat exchanger, and its surface is corroded.
Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of reasonable in design, is convenient to clean the sewage source heat pump shell and tube exchanger of maintenance, anti-corrosive properties height, long service life.
For achieving the above object, the utility model is taked following design: a kind of sewage source heat pump shell and tube exchanger, and it is made of metal shell and heat exchanger tube; Described heat exchanger tube is distributed in the inside of described metal shell; Side at described housing is provided with water inlet and the delivery port that links to each other with its internal heat exchange tubes, be provided with sewage inlet and outlet of sewer at the top of housing, sidewall at housing is provided with two clean-out openings, is furnished with port lid on the clean-out opening, is provided with sealing ring between port lid and clean-out opening.
Clean-out opening aperture on the described metal shell is 1/3～3/5 barrel dliameter.
Described heat exchanger tube is U type pipe or straight pipe type.
The utility model is owing to take above design, so have the following advantages: 1, because the utility model has additional clean-out opening at the sidewall of shell and tube exchanger metal shell, the user can clean, keep in repair heat exchanger tube directly with the foreign material on water under high pressure or other mode flushing heat exchanging pipes.2, because the utility model heat exchanger adopts corrosion resistant metal or alloy or other corrosion-resistant metal materials, composite to make, and take corresponding anticorrosion process as required, make the anti-corrosive properties of shell and tube exchanger improve, the life-span has prolonged.3, because the heat exchanger for heat pump diameter of the housing is big, the heat exchanger tube distribution is sparse, and sewage can unimpededly flow, so the housing internal pressure is little, and the requirement that housing is welded and seals is not very high, structure is also just simple relatively; Simultaneously, the big flow of circulating sewage can provide more heat, thereby guarantees the heat exchange effect of heat exchanger; In addition, heat exchanger is overall structure, and is easier for installation.

Fig. 2 is that Figure 1A-A is to side view
The specific embodiment
As shown in Figure 1, the utility model sewage source heat pump is made of metal shell 1 and heat exchanger tube 2 with shell and tube exchanger; Heat exchanger tube 2 is distributed in the inside of metal shell 1; Side at housing 1 is provided with water inlet 11 and the delivery port 12 that links to each other with its internal heat exchange tubes 2, is provided with sewage inlet 13 and outlet of sewer 14 at the top of housing 1.Sewage flows in the housing 1 from sewage inlet 13, flows out from outlet of sewer 14, when effluent stream is in housing 1, finishes exchange heat with heat exchanger tube 2; Simultaneously, foreign matter in the sewage and impurity also have been wrapped on the hot heat exchanger tube 2, influence the rate of heat exchange of heat exchanger.For this reason, as shown in Figure 1 and Figure 2, the utility model is provided with two clean- out openings 15,16 at the sidewall of heat exchanger metal shell 1, is furnished with port lid 17,18 on the clean-out opening 15,16, and 15,16 of port lid 17,18 and clean-out openings are provided with sealing ring and are fixed together by screw.
When being wound with more foreign matter or impurity on the heat exchanger tube 2, the user can open the clean-out opening port lid, directly cleans, keeps in repair heat exchanger tube in the housing with water under high pressure or other modes, make clean convenient.
The aperture of the clean-out opening 15,16 on the utility model shell and tube exchanger metal shell 1 can be 1/3～3/5 barrel dliameter, like this can be directly with the foreign material on water under high pressure or other mode flushing heat exchanging pipes.In addition, the quantity and the spacing of the deflection plate 19 in the housing 1 should be worked good with the quantity and the diameter of the clean-out opening of being offered, and promptly the maximum of each clean-out opening of being opened is cleaned diameter and can be flushed to the deflection plate or the case side of closing on, to guarantee the not having dead band of cleaning.
Because the corrosivity of sewage is stronger, therefore, the utility model heat exchanger can adopt corrosion resistant metal or alloy, makes as copper, copper alloy, stainless steel, titanium or titanium alloy or other corrosion-resistant metal materials and composite, and can take corresponding anticorrosion process as required.Because the NH in the sewage
4 +Ion pair copper and copper alloy have certain corrosiveness, and therefore, the heat exchanger tube of sewage heat exchanger adopts copper and copper alloy than the tube wall of conventional shell and tube exchanger thick 1～2 times.
Since abundant through the sewage resource that sewage treatment plant handled, in order to improve the heat exchange effect, save power, allow sewage low lift and large flow rate ground in shell, flow between pipe.The heat exchanger diameter that the utility model spy is common with the ratio of diameter of the housing design is big, and the distribution that makes heat exchanger tube is sparse and adopt U type pipe or straight pipe type with shell and tube exchanger than conventional air-conditioning.The flow of water can improve like this, on the one hand; Dirt in the water and impurity also are not easy to twine on the other hand, clean also more convenient.
Because it is sparse that the heat exchanger for heat pump diameter of the housing is big, heat exchanger tube distributes, sewage can unimpededly flow, so the housing internal pressure is little, and the requirement that housing is welded and seals is not very high, and structure is also just simple relatively; In addition, heat exchanger is overall structure, and is easier for installation.
