Abstract

The utility model relates to a primary sewage baffling board tubular heat exchanger of vertical directness with the primary sewage direct heat transfer in city. The problem of dirty water heat exchanger easily blockked up in the past, the heat transfer effect is poor and be hard to realize primary sewage and refrigerant direct heat transfer is solved. The device is become with snakelike heat exchange tube group by cuboid casing, baffling heat transfer board, and wherein snakelike heat exchange tube is hugged closely on the heat transfer board through the welded mode, and baffling heat transfer board welds on heat exchanger shell with certain inclination, forms between heat transfer board and the casing and turns to the circulation passageway of buckling. The device's working process does: primary sewage gets into the heat exchanger and flows past from heat exchanger upper portion entry and turns to the passageway of buckling, moves along the heat transfer plate current, turns to the back through buckle many times and flows out from heat exchanger lower part export, the refrigerant gets into snakelike heat exchange tube from the heat exchange tube entry of heat exchanger lower part, and from bottom to top covers heat transfer pipe flowing, flows into the heat exchange tube export on upper portion and flows out, completion heat transfer between mobile primary sewage of in -process and refrigerant.

Background technology
Along with raising China or even the whole world total energy consumption of economic development national product power increase year by year, a large amount of consumption of Fossil fuel, thus bring serious environmental problem, the energy lacks and problem of environmental pollution has become the significant problem that world faces。Therefore, the utilization of clean reproducible energy and Devoting Major Efforts To Developing become the important topic that we face, and are also the important channels realizing energy-conserving and environment-protective。Heat pump techniques, particularly carries out the application of sewage source heat pump technology of heat supply/cooling using Municipal Sewage Energy as low-grade heat source/low-temperature receiver and universal becomes one of effective way realizing energy-conserving and environment-protective, and increasingly receiving the concern of countries in the world。
Sewage source heat pump technology is divided into direct-type sewage source heat pump and indirect type sewage source heat pump now, wherein most effective with direct-type sewage source heat pump technomania, but development and the application of the blocking of the heat exchanger such as solid impurity and problem restricts always this technology such as sewage heat exchanger heat exchange efficiency is low in sewage。Sewage after having in some heat pumps before sewage heat exchanger in conventional research to add sewage filter device and utilize filtration is directly and the method for refrigerant heat exchanger, but the defecator in the method often to consume substantial amounts of electric energy equal energy source, filter effect is also not satisfactory simultaneously, it is extremely difficult to the direct-type sewage heat exchanger water quality requirement to sewage, therefore develop a kind of can directly and native sewage water heat exchange and low energy consumption heat-exchanger rig be improve Heat Pump efficiency, promote the effective way of sewage source heat pump technology application popularization。This utility model heat-exchanger rig is developed based on this。
Summary of the invention
Technical problem to be solved in the utility model is: overcome prior art not enough, it is provided that a kind of design uniqueness, low cost, power consumption are few, the vertical direct native sewage water deflection plate pipe heat exchanger that heat exchange efficiency is high。
The technical solution of the utility model is: a kind of vertical direct native sewage water deflection plate pipe heat exchanger, main by native sewage water entrance, native sewage water exports, heat exchanger shell, snakelike heat exchange tube entrance, snakelike heat exchange tube exports, snakelike heat exchange tube, heat exchanger plates forms, each snakelike heat exchange tube is respectively welded in each rectangular heat exchanger plate, heat exchanger plates and heat exchanger perpendicular bisector are that acute angle interval from top to bottom is alternately welded on the housing of the internal opposite sides of heat exchanger, form the circulation passage turning to baffling, and each snakelike heat exchange tube is connected as one by the mode connected。
Described native sewage water entrance is arranged in top, as it is shown in figure 1, native sewage water directly enters heat exchanger from this entrance through conveying equipments such as sewage transport pumps。
The outlet of described native sewage water is disposed below, as it is shown in figure 1, native sewage water completes to be flowed out by this outlet after heat exchange through heat exchanger。
Described snakelike heat exchange tube entrance is disposed below, as in figure 2 it is shown, cold-producing medium enters in snakelike heat exchange tube from this entrance。
The outlet of described snakelike heat exchange tube is arranged in top, as in figure 2 it is shown, cold-producing medium and sewage flow out from this outlet after completing heat exchange。
Described heat exchanger plates, such as Fig. 1 and Fig. 2, for smooth metallic flat board, is welded on heat exchanger shell, and flat board and heat exchanger shell perpendicular bisector angle are acute angle。
Described heat exchanger shell, such as Fig. 1 and Fig. 2, in cuboid, heat exchanger shell is integrally welded with heat exchanger plates, and forms, with heat exchanger plates, the circulation passage that bending turns to, and heat exchanger shell material adopts 316L rustless steel。
Described snakelike heat exchange tube, as in figure 2 it is shown, be welded on the face of heat exchanger plates bottom by a heat exchanger tube bending, the snakelike heat exchange tube on each heat exchanger plates connects into one with elbow each other。
The beneficial effects of the utility model:
1. this utility model good economy performance, its simple in construction, it is easy to processing and installation, reduce construction cost;
2. in this utility model, cold-producing medium and native sewage water are made directly heat exchange, eliminate the energy loss of existing indirect heat exchange process, substantially increase heat exchange efficiency。
3., in the heat transfer process of this utility model native sewage water and cold-producing medium, sewage relies on action of gravity flowing, does not additionally consume energy, and can effectively save the energy consumptions such as electric energy, reduces operating cost。
4. this utility model heat exchanger plates is smooth with native sewage water contact surface, and heat exchanger plates and heat exchanger shell perpendicular bisector have certain angle, and dirt is difficult to adhere to so that heat exchanger plates dirtiness resistance is less;Meanwhile, heat exchanger plates forms, with heat exchanger shell, the flow channel turning to bending, can produce strong disturbance when native sewage water flows through heat exchanger plates, and heat exchange is strengthened, and heat exchange efficiency is higher。
