Technical field
It the utility model is related to field of energy utilization, more particularly to a kind of vertical rotating sewage heat exchanger.
Background technology
Municipal sewage alternative partial fuel coal, oil burning boiler, can suitably alleviate me as a kind of reproducible low-temperature heat source
The environmental problem of state, and the energy resource structure in China can be optimized, to the significant of national energy-saving emission reduction.
Sewage heat exchanger is the key equipment for realizing municipal sewage Btu utilization, and sewage and clean water are in sewage heat exchanger
Realize contactless heat exchange.However, sewage is introduced into heat exchanger, inevitably exchanged heat as a kind of severe water quality
Fouling on surface, heat exchange surface thermal resistance is caused to increase, heat exchanger total heat transfer coefficient declines quickly.Sewage dirt can even block
Heat exchanging pipe, influence heat exchanger and continually and steadily exchange heat.Therefore, there is easy fouling in sewage heat exchanger, and hardly possible cleaning, easily blocking etc. are many
Technical barrier.
At present sewage heat exchanger mainly have immersion, shell-and-tube, showering spray type these three.Immersion sewage heat exchanger is by sewage
Heat exchanger is immersed directly in cesspit pond, has good anticorrosion and anti-clogging performance.But heat exchange mode is nature pair
Stream, heat exchange efficiency is low, and heat exchange area is big, and the dirt deposition in the pond that exchanges heat also is difficult to solve with cleaning, is not suitable in heavy construction
Middle popularization.Pipe shell type sewage water heat exchanger heat transfer form is forced convertion, and heat transfer coefficient is big, but cleans difficult, maintenance workload
It is larger.Showering spray type sewage heat exchanger efficiently solves the obstruction scale problems of heat exchanger, and heat transfer coefficient is higher.But heat exchanger table
Periodic purge is needed on the outside of face, and the cycle is short, secondary pollution be present in formal system.
The utility model proposes a kind of vertical rotating sewage heat exchanger, in the absence of dirty stifled problem, utilizes the rotation of heat exchanger tube
Turn, there is augmentation of heat transfer and certain scale removal ability, coordinate rubber ball cleaning, it is possible to achieve the real-time online of heat exchanger is free of demolition clear
Wash.Exchange heat as forced convertion, and clean water and sewage are countercurrent flows.The utility model overcomes the shortcomings that above-mentioned heat exchanger,
To better profit from sewage resource, there is provided a kind of new approaches and methods.
The content of the invention
The utility model purpose is to provide a kind of vertical rotating sewage heat exchanger, can realize real-time online rubber ball cleaning, tool

Connection device is fixed on the top surface of casing 1 and bottom surface.Spiral heat exchange plate 7 includes upper and lower two heat-transfer surfaces, and centre is hollow, is formed
The flow channel of clear water.Two heat-transfer surface one end and the rotary shaft 6 of heat exchanger plates 7 weld together, other end end-enclosed and away from
There is small―gap suture from the internal face of casing 1.The foot of rotary shaft 6 inside casing 1 open one section of spiral mouth with it is spiral helicine
Heat exchanger plates 7 weld, and the topmost of the rotary shaft 6 inside casing 1 is opened one section of spiral mouth and welded with spiral helicine heat exchanger plates 7
Connect, the remainder of rotary shaft 6 directly welds with spiral heat exchange plate 7.The intermediate tube internal cavities of rotary shaft 6 are using filling material
Material tamps, and both ends retain internal cavities and are easy to clear water to flow.The part that the bottom of rotary shaft 6 is exposed at outside casing 1 is equiped with driven
Wheel 8, is connected with the driving wheel 9 that motor 10 drives by gear or belt, realizes rotating shaft 6 and the rotation of heat exchanger plates 7.Rotate
Realized by shaft connector 11 and clear water inlet duct 2 and clear water output pipeline 3 part that axle 6 stretches out casing upper and lower end parts
Connection.
The lateral surface of casing 1 is provided with rubber ball cleaning circulation pipe 18, the top of the top of circulation pipe 18 connection box heat exchanger 1, follows
The bottom of endless tube 18 connection box heat exchanger 1 bottom.Circulation pipe 18 is provided with glueballs circulation valve 12, on circulation valve 12
Side has pipeline to be connected with receiving Ball valve 13 and receiving ball room 15.Ball room is received as service room, its bottom is provided with pipeline and service valve
17 are connected with rubber ball cleaning circulation pipe 18.Receive the lateral surface of ball room 15 and be provided with a loose-leaf inward swinging door 14, be easy to take out outward
Glueballs adds glueballs inward.During normal heat exchange, rotary shaft 6 is motionless, it is necessary to when cleaning, and closes wastewater inlet valve and clear
Water inlet valve, sewage and clear water is not allowed to enter heat exchanger.Motor 10 is then turned on, drives driving wheel 9 to rotate, driving wheel 9
It is connected by belt or gear with driven pulley 8, drives driven pulley 8 to rotate, so as to realize the rotation of axle 6 and spiral heat exchange plate 7.

Part between shape opening is tamped with filler, does not allow clear water to pass through.
Sewage enters heat exchanger from the sewage inlet 4 on top, along the spiral shell formed between two neighboring spiral heat exchange plate 7
The space of rotation shape is flowed from top to bottom, after reaching exchanger base, drains along outlet of sewer 5.Sewage also can be along heat exchanger plates 7
With the interstitial flow between the internal face of casing 1, but the very little of the void designs, therefore most of sewage is still along spiral
The spatial flow of shape.Sewage flows from top to bottom along helical space, and there is souring in heat exchanging face, and dirt is in current scour
Under Action of Gravity Field, it is not easy to accumulate.Therefore, the heat exchanger has certain self-cleaning action, between the time for extending heat exchanger cleaning
Every.
As shown in figure 3, shaft connector 11 includes connecting bolt 111, the airtight and watertight padding 112 of rotary shaft, the company of rotary shaft
The connecting bushing 114 of spindle set 113 and dead axle forms.Filler uses the anti abrasive filler of good airproof performance, ensure that rotation
Axle will not leak in rotation reclaimed water.
Because two heat exchange surfaces up and down of heat exchanger plates 7 and the inner surface of casing 1 are the contact surface of sewage, therefore, change
Hot plate 7 preferably uses stainless steel material, in order to prevent dirt from depositing, can use polishing.
The utility model is applied to sewage heat change, and sewage runner uses wide runner, and runner inside is unobstructed, is not easily blocked, changes
Clear water in hot device carries out countercurrent flow with sewage, and heat transfer temperature difference is larger, and heat exchange efficiency is higher.Also, dirt of the present utility model
Water- to-water heat exchanger, glueballs on-line cleaning is employed, suitable for the heat exchange of the poor sewage of water quality.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model should be included in
Within the scope of protection.
