Abstract
A kind of source of sewage high-efficiency heat exchanger uses flat-faced tube helical flow path, the flowing for being conducive to dirty fluid is smooth, no-sundries can be with helical flow path by its own gravity and water impact, and the case where preventing dirty sundries obstruction heat exchanger completely occurs, and increases the contact surface of heat exchanger sewage and clear water.According to the actual state of engineering project, the actual demands such as hot-cold fluid flow, heat exchange area, heat exchange amount size can extend the spiral number of plies, also improve heat exchange amount and heat exchange efficiency using form in parallel or series.
Description
Technical field
The present invention relates to field of heat exchange equipment, are related to a kind of source of sewage high-efficiency heat exchanger.
Background technology
More and more social concerns such as population growth at present, environmental pollution receive people's concern, and resource shortage is 21
Century becomes the crisis of global facing again.Therefore, it is the needs of environmental protection and energy saving using regenerative resource.Using heat pump skill
Art is to realize one of the effective way of sewage heat energy comprehensive utilization using Municipal Sewage Energy as low level heat energy heat supply/refrigeration.
This regenerative resource of city waste heat in sewage is contained in recycling, expands the benefit of municipal sewage treatment and using energy source, real
Existing Sewage treatment recycles, and embodies the requirement of " Developing Circulation Economy builds resource-saving city ".But municipal sewage simultaneously
The primary problem of heat energy utilization is how to avoid a large amount of solid dirt sundries contained in sewage to block heat transmission equipment.It is former to solve
Crude sewage blocks the problem of heat exchanger, and the present invention reaches good anti-blocking heat exchange by designing special flat spin plate-type heat-exchange
Effect.
Invention content
It is easily blocked for existing heat exchanger, the problems such as heat exchange efficiency is not high, the present invention uses flat-faced tube helical flow path, has
Flowing conducive to dirty fluid is smooth, and no-sundries can completely prevent dirty miscellaneous with helical flow path by its own gravity and water impact
The case where object obstruction heat exchanger, occurs, and increases the contact surface of heat exchanger sewage and clear water.According to the actual state of engineering project,
The actual demands such as hot-cold fluid flow, heat exchange area, heat exchange amount size, can extend the spiral number of plies, also using in parallel or string
The form of connection improves heat exchange amount and heat exchange efficiency.
The present invention is that technical scheme applied to solve the technical problem is：
1, sewage enters from sewage inlet at the top of flat spin plate heat exchanger, flows into sewage spiral bin, sewage can be along spiral shell
Rotation storehouse is rotated down flowing, dirty to ensure that the passability of sewage, the sectional area of sewage spiral bin are less than the sectional area of sewage inlet
The big flow velocity of pressure in water spiral bin is fast, contributes to the promotion of dirty sundries, finally from the sewage of flat spin plate heat exchanger bottom
Outlet discharge；
2, clear water enters from flat spin plate heat exchanger bottom, and clear water is not required to consider anti-blocking problem, therefore from lower water inlet, with
Sewage stroke adverse current has exported after filling spiral bin from clear water output at the top of flat spin plate heat exchanger into clear water spiral bin
At heat exchange.
3, clear water spiral bin inner wall is sewage spiral bin outer wall, and sewage spiral bin superlative is clear water spiral bin inner wall, only one
It opens iron plate to be separated by, two-sided heat exchange.
4, sewage spiral bin height is higher than clear water spiral bin, ensures the discharge of sewage.
The beneficial effects of the invention are as follows：
1, while flat spin heat exchange can effectively improve heat exchange efficiency, the effective means of obstruction heat transmission equipment, profit are avoided
With the characteristic of dirty sundries and sewage itself, sewage flow is threadingly advanced downwards, and heat exchanger is integrally rounded, therefore is not in dirt
The case where sundries wall built-up；
2, sewage flows from the top to the bottom, and clear water flows from bottom to top, stroke reverse flow, can get best heat transfer effect.
Description of the drawings
Fig. 1 is the stereogram of the present invention, and Fig. 2 is the sectional view of the present invention；Wherein：
1. clear water output, 2. wastewater inlets, 3. clear water imports, 4. outlets of sewer, 5. sewage spiral bins, 6. clear water spirals
Storehouse.
Specific implementation mode
As shown in Figure 1, sewage enters sewage spiral bin 5 from wastewater inlet 2, advance is rotated down in a manner of snail,
It is discharged from outlet of sewer 4, clear water enters clear water spiral bin from clear water import 3, is threadingly advanced upwards by snail, from clear water
1 discharge of outlet, completes heat exchange.
Claims (2)
1. flat spin plate heat exchanger, the method is entered from sewage inlet at the top of flat spin plate heat exchanger by sewage,
Sewage spiral bin is flowed into, sewage can be rotated down flowing along spiral bin, to ensure that the passability of sewage, sewage spiral bin are cut
Area is less than the sectional area of sewage inlet, and the big flow velocity of pressure in sewage spiral bin is fast, contributes to the promotion of dirty sundries, finally from
The outlet of sewer of flat spin plate heat exchanger bottom is discharged.
2. flat spin plate heat exchanger as described in claim 1, it is characterised in that：Clear water is from flat spin plate heat exchanger bottom
Into clear water is not required to consider anti-blocking problem, therefore, into clear water spiral bin, fills spiral from lower water inlet with sewage stroke adverse current
Heat exchange is completed from clear water output output at the top of flat spin plate heat exchanger behind storehouse, clear water spiral bin inner wall is outside sewage spiral bin
Wall, sewage spiral bin superlative are clear water spiral bin inner walls, and an only iron plate is separated by, two-sided heat exchange.
