Abstract

The utility model relates to a highly-effective sewage heat exchanger. A spiral metal flow deflector is wound at the straight pipe part of a coiled pipe, sleeve pipes with stoppers at both ends are sheathed at the outer side of the metal flow deflector, and a medium communicating pipe is arranged between every two sleeve pipes. The highly-effective sewage heat exchanger has the advantages of compact structure, reasonable design and easy installation; when the heat exchanger is adopted for sewage heat exchange, since the medium flows in the sleeve pipes, the sewage flows in the coiled pipe, andthe medium and the sewage flow oppositely to form convective flow; and the heat exchanger has effective heat exchange effect, small volume and small occupied area, is particularly suitable for low-temperature sewage heat exchange, has high heat exchange efficiency, saves power consumption during heat exchange, saves a great amount of energy and has low comprehensive cost.

Description

The wastewater efficient heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, especially relates to a kind of wastewater efficient heat exchanger.

Background technology

At present, heat exchanger is used in sewage disposal, adopt large-scale tank usually, in sump, install a plurality of serial connections or and the coiled pipe that connects, media flow is arranged in the coiled pipe, the cell body two ends are provided with sewage and import and export, yet above-mentioned heat-exchanger rig volume is big, floor space is big, and cost height, heat exchange efficiency are low.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and volume is little, in light weight, and the wastewater efficient heat exchanger that heat exchange efficiency is high easily is installed.

In order to achieve the above object, the technical solution adopted in the utility model is: at coiled pipe straight tube position winding screw shape metal flow deflector, its outside is set with the sleeve pipe of two ends band shutoff, is provided with medium communicating pipe between per two sleeve pipes.

The utility model has the advantages that:

1, compact conformation, reasonable in design is easily installed, and when adopting this device to carry out the sewage heat exchange, because medium flows in sleeve pipe, sewage flows in coiled pipe, and medium and sewage subtend flow, and form convection current, and heat exchanger has heat exchange effect efficiently;

2, the utility model volume is little, floor space is little;

3, the utility model is specially adapted to low-temperature sewage heat exchange and heat exchange efficiency height, and a large amount of energy are saved in the heat transfer process power consumptive province, and integrated cost is low.

Description of drawings

Fig. 1 is the utility model structural representation;

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, the utility model is at coiled pipe 1 straight tube position winding screw shape metal flow deflector 2, and its outside is set with the sleeve pipe 3 of two ends band shutoff, is provided with medium communicating pipe 4 between per two sleeve pipes 3.

Described coiled pipe 1 two ends and bend pipe position are equipped with respectively and are opened movable joint 5 soon.

Coiled pipe 1 described in the utility model adopts thin-wall stainless steel polishing pipe, sleeve pipe 3 adopts metal material, sewage pumps into heat exchanger sewage inlet 8 by filter screen by sewage pump during heat exchange, discharge by coiled pipe outlet 9 again, medium enters by medium inlet 6, through the metal flow deflector 2 in the sleeve pipe 3 velocity of medium is accelerated, discharge through media outlet 7, reciprocation cycle is used, because the sewage in the coiled pipe 1 flows fast, dirt is difficult for being stranded in the coiled pipe 1, make coiled pipe 1 tube wall adsorbate and impurity few, be difficult for to stop up, the utility model at coiled pipe 1 two ends and pipe bent position be equipped with and open movable joint 5 soon, be convenient to the operating personnel and check, dirt on maintenance and cleaning coiled pipe 1 inwall.The utility model can be connected in series mutually or and be connect use by one or more wastewater efficient heat exchanger.
