Abstract
The utility model provides a spiral tubular flue heat exchanger contains casing (1) and spiral pipe (2), casing (1) contains flue gas entry (11) and exhanst gas outlet (12), spiral pipe (2) contain water inlet (21) and delivery port (22), this heat exchanger is supporting to be provided with steam pocket (3) and circulating pump (4), and wherein steam pocket inlet tube (31) are connected with spiral pipe delivery port (22), and outlet pipe (32) are connected with spiral pipe water inlet (21) through circulating pump (4), form the hydrologic cycle route. This heat exchanger operation in -process, circulating water and flue gas carry out reverse heat exchange, and output high -temperature steam passes through the steam pocket and goes out steam pipe (33) and supply with other and need heat supply production processes, realizes to sum up that flue gas part waste heat recovery utilizes. Furthermore, the utility model provides a spiral tubular flue heat exchanger, internal drag is little and occupation space is little, but the current flue of direct replacement reduces the flue heat and scatters and disappears.
Description
Technical field
This utility model is related to a kind of flue gas waste heat recovery technical field, particularly a kind of helix tube type chimney heat exchanger.
Background technology
At present, the field of industrial production such as domestic generating, iron and steel, chemical industry, heat supply, flue gas heat recovery have become focus
Subject under discussion.In existing flue gas heat recovery technique, it is commonly designed on the basis of original underground flue and further builds on the ground
Flue path so as to which the heat transmission equipment such as air preheater, heat exchanger or boiler with relevant position is connected, and realizes waste heat recovery.
However, due to there is the restriction of job site space, often needing the longer flue of design, the flue gas Jing flue processes of circulation to inevitably result in
Partial heat scatters and disappears, so as to reduce waste heat recovery rate.
The content of the invention
For the lost problem of flue residue heat, the present invention provides a kind of helix tube type chimney heat exchanger, and which directly can substitute
Partly upper flue, while reclaim flue heat.
The technical scheme of this utility model solve problem is as follows：A kind of helix tube type chimney heat exchanger, comprising housing and spiral shell
Coil；Its housing is vertical cylinder structure, comprising smoke inlet and exhanst gas outlet；Serpentine pipe includes water inlet and outlet；
The helix tube type chimney heat exchanger is simultaneously equipped with drum and circulating pump；Drum includes water inlet pipe, outlet pipe and steam outlet pipe；
The serpentine pipe water inlet is connected with drum outlet pipe, and serpentine pipe outlet is connected with drum water inlet pipe.
During use, the water upper entering and lower leaving in serpentine pipe, flue gas bottom in and top out are formed in counter current heat exchange, drum and are produced
Go out steam and be delivered to the production link for needing heat supply by steam outlet pipe.
The helix tube type chimney heat exchanger low cost, while appropriate design can be done to its size according to flue size, with reference to
The characteristics of its internal helicoid heat exchanger tube resistance is little, can directly substitute existing part flue structure, make full use of narrow space
Heat recovery is done, flue heat is reduced and is scattered and disappeared.
Description of the drawings
Fig. 1 is helix tube type chimney heat exchanger of the present invention.
Specific embodiment
In order to more clearly explain this utility model, spy describes in detail as an example, but right required by this utility model is not
Only in this.
A kind of helix tube type chimney heat exchanger as shown in Figure 1, containing housing（1）And serpentine pipe（2）；Housing（1）It is vertical
Formula cylindrical structure, upper and lower side are respectively equipped with exhanst gas outlet（12）And smoke inlet（11）；Serpentine pipe（2）Comprising water inlet（21）
And outlet（22）；It is supporting with the heat exchanger to be provided with drum（3）And circulating pump（4）, wherein drum（3）Containing water inlet pipe（31）、
Outlet pipe（32）And steam outlet pipe（33）, water inlet pipe（31）With serpentine pipe outlet（22）Connection, outlet pipe（32）By circulation
Pump（4）With serpentine pipe water inlet（21）Connection, forms water circulation path；Additionally, the helix tube type chimney heat exchanger produces high temperature steaming
Vapour passes through drum steam outlet pipe（33）Supplying other needs heat supply production link, to sum up realizes flue gas partial heat recovery.This changes
In hot device running, from underground flue（5）The high-temperature flue gas of transmission are bottom-up to be carried out inversely with water that is from up to down circulating
Heat exchange, high-temperature-hot-water is from outlet（22）The instant vaporization in drum, produces steam from steam outlet pipe（33）Discharge, while vapour
Water Jing circulating pumps in bag（4）Effect is from water inlet（31）Into helix tube type chimney heat exchanger, water circulation heat exchange is realized.
This helix tube type chimney heat exchanger, composition are simple, low cost, and small volume, diameter of the housing can be according to flue sizes
And space size is adjusted so as to adapt to technological requirement.Additionally, serpentine pipe resistance is less, system pressure affects unobvious.Cause
This, the vertical flue built can directly be replaced with helix tube type chimney heat exchanger by us, reduce flue heat and scatter and disappear,
Improve fume afterheat utilization rate.
Claims (2)
1. a kind of helix tube type chimney heat exchanger, which includes housing（1）And serpentine pipe（2）；The housing（1）Comprising smoke inlet
（11）And exhanst gas outlet（12）；The serpentine pipe（2）Comprising water inlet（21）And outlet（22）, it is characterised in that：The spiral shell
Coil formula chimney heat exchanger water inlet（21）By circulating pump（4）With drum outlet（32）Connection；The helix tube type flue
Heat exchanger outlet（22）With drum water inlet（31）Connection.
