Abstract

The utility model relates to a corrugated plate type heat exchanger belonging to heat exchangers used in the chemical engineering field. The utility model is characterized in that the utility model is composed of cold pipes, hot pipes, partition plates and stream controlling plates. The central sections of the partition plates are folded into page plates in an S shape. The stream controlling plates are installed on the two sides of the page plate. The cold pipes and the hot pipes are positioned at the external sides of the stream controlling plates. The two ends of the partition plates are circled into an elliptical casing to pack the page plates, the stream controlling plates, the hot pipes and the cold pipes. The two end heads of the heat exchanger are provided with end clamping plates in a clamping mode. Gap raised heads among page plates have small controllable page plate gaps, and the utility model has the advantages of compact structure, good turbulent flow degree, high heat exchange efficiency, small utilized materials, high effective material utilization rate, simple fabrication process, less invested cost for processing equipment and low cost.

Description

Ripple page or leaf plate type heat exchanger

One, technical field

The utility model belongs to the heat exchanger that chemical field uses.

Two, background technology

Existing spiral heat exchanger is made on the private volume bed by two blocks of parallel steel plates.Every block plate is by while coiling shape, and forms two concentric channels, and its cross section is a rectangle, imports and exports and takes over the marginal end that is loaded on two passages respectively.This class heat exchanger precision of manufacturing process requires high, needs with expensive special equipment processing.

The structure of existing plate type heat exchanger is to be arranged at regular intervals by one group of heat transfer plate, compress by pad to be installed together, but its seal perimeter is long, and complex manufacturing, production cost is higher.

Three, summary of the invention

The purpose of this utility model provides a kind of ripple page or leaf plate type heat exchanger, and production technology is simple, low processing cost, compact conformation, good effect of heat exchange.

The utility model is achieved in that ripple page or leaf plate type heat exchanger, is made up of cold pipeline 2, hot channel 3, dividing plate 1 and control stream plate 6, and the mid portion of dividing plate 1 is folded into page plate 5 by S shape, and control stream plate 6 is installed in the both sides of page or leaf plate 5; Cold pipeline 2, hot channel 3 are positioned at the outside of control stream plate 6, and the two end portions of dividing plate 1 encompasses an oval-shaped shell with page or leaf plate 5, control stream plate 6, hot channel 3, cold pipeline 2 parcels, clamp in the two ends of heat exchanger end clamping plate 4 are installed; On page or leaf plate 5, be processed with the waveform of inclination; Be processed with on the page or leaf plate 5 and decide crack plush copper 14.

Hot channel 3 is provided with hot water inlet 8, hot water outlet 10; Cold pipeline 2 is provided with cold water inlet 9, cold delivery port 7.

Compare with existing heat exchanger, the beneficial effects of the utility model are:

1, can to control page sheet separation very little for the decide crack plush copper of page or leaf between plate, compact conformation; Can on original heat exchange pipeline, improve heat exchange structure, not take the device space;

2, because the page or leaf plate adopts the wavy shaped configuration of inclination, simultaneously, be processed with on the wave plate and decide the crack projection, make the fluid turbulent degree good, the heat exchange efficiency height;

3, the inner page or leaf of shell multilayer parcel plate is very thin, and material uses few, the effective rate of utilization height of material;

4, the processing technology difficulty is low, and manufacture craft is simple, process equipment less investment, low production cost.

Five, the specific embodiment

Dividing plate 1 mid portion of the utility model ripple page or leaf plate type heat exchanger is folded into page plate 5 along S shape, and two ends are walked around hot and cold pipeline respectively as shell; The shell internal layer is corrugated, and skin is dull and stereotyped, and the centre is filled with filler 11; Rear and front end at heat exchanger clamps with end clamping plate 4, the gas welding sealing; Control stream plate 6 is installed on hot and cold pipeline, forms the space of a sealing, page or leaf plate 5 is divided into heat exchanger between hot and cold two heat transfer zone; As shown in Figure 4, the left side is a cold water area 12, and the right side is hydrothermal area 13.

Cold water enters a page sheet heat exchanger by cold flow pipeline bottom horizontal flow sheet from front to back by the cold water pipe water inlet, accept heat after, enter cold pipeline by the cold water flow export and discharge.

In like manner, hot water passes through hot-fluid pipeline bottom horizontal flow sheet from back to front, enters a page sheet heat exchanger by the hot-water line water inlet, after the exchange heat, enters hot channel by the flow of hot water outlet and discharges.

Be processed with corrugated dividing plate 1 part and be folded into page plate 5 along S shape, the ripple incline direction of adjacent page plate 5 is corresponding, has formed the corrugated channel that tilts like this in the slit of 5 of page or leaf plates; Ripple bearing of trend and pipeline inclination certain angle on the page or leaf plate 5 make fluid that the trend that along inclined direction flows be arranged, and have reduced the flow dead of slit, have improved the utilization rate of page or leaf plate.

Appropriate location at hot and cold water pipe processes water inlet and delivery port respectively, and the mid portion of water pipe is blocked, and to prevent water from pipeline intermediate flow mistake, control stream plate 6 is housed around the pipeline, and the control fluid enters and carries out heat exchange in page plate.
