Abstract
The utility model relates to a with the board -like dirty water heat exchanger device of the spiral pipe of 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 by cylindrical casing, spiral heat transfer board and spiral heat exchange tube group, and wherein the spiral heat exchange tube is hugged closely on the heat transfer board through the welded mode, and spiral heat transfer board welds in the circular cylindrical shell internally, forms the passageway of spiral between heat transfer board and the casing. The device's working process does: primary sewage is from heat exchanger upper portion entry entering heat exchanger and flow past helical coiled passage, flows out from heat exchanger lower part export, the refrigerant gets into the spiral heat exchange tube from the heat exchange tube entry collection case of heat exchanger lower part, and from bottom to top flows, flows into the heat exchange tube export collection case on upper portion and flows out, completion heat transfer between mobile primary sewage of in -process and refrigerant.

Technical field
The utility model relates to a kind of directly sewage source heat pump sewage heat change system, the particularly spiral of a kind of cold-producing medium and native sewage water direct heat transferTube-sheet heat exchanger.
Background technology
Along with the total power consumption of raising China and even the whole world of economic development national product power increases year by year, a large amount of consumption of fossil fuel, bring tight thusHeavy problem of environmental pollution, the energy lacks and problem of environmental pollution has become the significant problem that world faces. Therefore, cleaning can be againUtilization and the Devoting Major Efforts To Developing of the raw energy become the important topic that we face, and are also the important channels of realizing energy-conserving and environment-protective. Heat pump techniques, specialThat the sewage source heat pump technology of carrying out heat supply/cooling using Municipal Sewage Energy as low-grade heat source/low-temperature receiver becomes effective way of realizing energy-conserving and environment-protectiveOne of footpath, and more and more receive the concern of countries in the world.
Existing sewage source heat pump technology is divided into direct-type sewage source heat pump and indirect type sewage source heat pump, wherein with direct-type sewage source heat pump technomaniaMost effective, but the obstruction 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 sewageDevelopment. In research in the past, there are some heat pumps to add sewage filter device and utilize sewage after filtering directly and the side of cold-producing medium heat exchangeMethod, but the filter in the method often will consume a large amount of electric energy equal energy sources, and filter effect is also not satisfactory simultaneously, is difficult to reach straightConnect the water quality requirement of formula sewage heat exchanger to sewage, therefore develop a kind of can be directly and the heat-exchanger rig of native sewage water heat exchange be to reduce energy consumption, carryThe effective way of high Heat Pump efficiency. Develop the utility model heat-exchanger rig based on this.
Summary of the invention
Technical problem to be solved in the utility model is: overcome prior art deficiency, provide a kind of design uniqueness, low cost, power consumption few, heat exchangeThe direct native sewage water helical tube plate type heat exchanger that efficiency is high.
The technical solution of the utility model is: a kind of directly native sewage water helical tube plate type heat exchanger, mainly, by native sewage water entrance, native sewage water goes outMouthful, refrigerant inlet header, refrigerant outlet header, spiral heat exchange tube, spiral heat exchanger plates, heat exchanger shell composition.
Described native sewage water entrance is arranged in top, and as shown in Figure 1, native sewage water directly enters from this after after the conveying equipment such as sewage transport pump is carriedMouth enters heat exchanger.
Described native sewage water outlet is arranged in below, and as shown in Figure 1, native sewage water is flowed out by this outlet after heat exchanger completes exchange heat.Described refrigerant inlet header is arranged in below, and as depicted in figs. 1 and 2, refrigerant inlet header connects each spiral heat exchange tube entrance, its workWith being shunting, by cold-producing medium mean allocation in each spiral heat exchange tube.
Described refrigerant outlet header is arranged in top, and as depicted in figs. 1 and 2, refrigerant outlet header connects each spiral heat exchange tube outlet, its workWith being to conflux, collect by the cold-producing medium of each spiral heat exchange tube outlet.
Described spiral heat exchanger plates, as Fig. 1 and Fig. 2, is reversed and is formed spirality by flat board.
Described heat exchanger shell, as Fig. 1 and Fig. 2, is divided into external shell and inner shell two parts, and cylindrical, heat exchanger shell and spiral changeHot plate welding is integral, forms spirality fluid passage.
Described spiral heat exchange tube, as depicted in figs. 1 and 2, is formed by several parallel the spiraling of heat exchanger tube, and spiral heat exchange tube is close to by the mode of weldingOn spiral heat exchanger plates.
The beneficial effects of the utility model:
1. the utility model good economy performance, it is simple in structure, is easy to processing and installs, and has reduced construction cost;
2. in the utility model, cold-producing medium and native sewage water directly carry out heat exchange, have eliminated the energy loss of existing indirect heat exchange process, greatly improveHeat exchange efficiency.
3. in the heat transfer process of the utility model native sewage water and cold-producing medium, sewage relies on Action of Gravity Field to flow, and additionally power consumption, can effectively not save electricityThe energy consumptions such as energy, reduce operating cost.
4. the utility model spiral heat exchanger plates and native sewage water contact-making surface are smooth, and dirt is difficult to adhere to, and make heat exchanger plates dirtiness resistance less; Meanwhile,Heat exchanger plates twist, can produce strong disturbance when native sewage water flows through heat exchanger plates, and heat exchange is strengthened, and heat exchange efficiency is higher.
5. the utility model heat exchange area can be adjusted flexibly according to heat exchange load, can adjust spiral heat exchanger plates pitch according to native sewage water water quality simultaneously,Make simple and flexible in design process.
