Abstract
The utility model relates to a flat spiral tube type heat exchanger, which is a novel waste heat recovery unit and is used for the waste heat recovery of the hot waste water in the textile industry. The utility model adopts the structure that a plurality of flat spiral tubes are connected in parallel, and distributes the city water into all the flat spiral tubes by positioning shafts and diversion conduits. The city water is in the tubes, and the hot waste water is outside the tubes, and the city water and the hot waste water form the strict and organized countercurrent flow heat exchange. The heat exchange is reinforced and is not easy to have fouling under the function of the secondary flow.
Description
In light and textile industries, the especially printing and dyeing mill, spent hot water's resource exception is abundant, supplies with the technical process use if reclaim one part heat with suitable method, then can save a large amount of energy.The equipment that reclaims spent hot water's waste heat at present is generally plate type heat exchanger (as the BR-12 plate type heat exchanger of Hangzhou Dyeing and Printing Factory's use).But the heat exchanger plates of board-like heat exchanger is an integral solder, can not dismounting, and heat exchange element can not be changed, and inconvenience is cleaned, and structure is not compact, and volume is big.In order to improve these shortcomings, we have developed novel waste heat recovery apparatus---plane screwed pipe heat exchanger.
The structure of plane screwed pipe heat exchanger as shown in drawings.
Heat exchanger is made up of the plane screwed pipe (1) and the shell (2) of a plurality of parallel connections, and its profile is cylindrical.Shell is formed by iron casting, the plane screwed pipe is bent by special equipment with copper tube and forms, the two ends of the many rows plane screwed pipe parallel connection annulus (3) of burn-oning, annulus is enclosed within on the locating shaft (4) again, thereby locating shaft not only plays the positioning actions of many rows screwed pipe in parallel, and plays a part to distribute running water (locating shaft is hollow) to each row plane screwed pipe.Place plasticity pad (5) between annulus, compress with upper cover plate (6) during device.Each is arranged and inserts pin (7), the pitch in coil that is used to be maintained fixed between screwed pipe in parallel.Pin can not one be inserted into the end, otherwise can hinder spent hot water's runner, should insert across with short pin.
Heat exchanger does not need water pump, and is mobile in heat exchanger by running water and spent hot water's pressure head.Running water flows in pipe, and the spent hot water is flowed in that pipe is outer, thereby has formed strictness and organized countercurrent flow, adds the effect of secondary stream and makes the heat exchange enhancing (heat transfer coefficient reaches K=4000KJ/m
2. ℃ .h), and secondary stream has the clean effect of order, so less scaling.The plane screwed pipe has spring action, thereby has avoided owing to breaking of causing of thermal stress and leak.
This heat exchanger uses over a long time through the test of Zhejiang Province's power-saving technology centring system and in Hangzhou Dyeing and Printing Factory, proves that energy-saving effect is remarkable, and its main performance index has reached advanced international level.
This heat exchanger has identical purposes and flow with the BR-12 plate type heat exchanger that uses for a long time in Hangzhou Dyeing and Printing Factory, thereby has real comparativity.Both relatively see the following form:
| Heat loss rate | Volume | The heat exchange area of unit volume | The heat exchange element selling price | ||
| Plane screwed pipe heat exchanger | <5% | 0.12m 3 | 91m 2/m 3 | Removable cleaning about 4000 yuan and replacing | |
| The BR-12 plate type heat exchanger | 10～15 | 0.41m 3 | 29m 2/m 3 | Can not take honest and upright and thrifty 7000 yuan apart washes and changes | |
