Description
Technical field
The utility model relates to heat exchanger, specifically a kind of sewage plate type heat exchanger.
Background technology
Sewage heat exchanger is the front-end product in sewage source heat pump system, be mainly used to extract the heat be dispersed in the sewage such as urban original wastewater, industrial wastewater, washing slag water, dyeing waste water winter, pass to source pump by intermediary's water coke slurry, promote through source pump and heat to building, summer passes to the heat of building the inside in sewage, to architecture refrigerating, this has not only saved the energy, and decrease the consumption of environmental pollution and water resource, its appearance makes sewage not enter source pump, avoid the Corrosion blockage of sewage to unit, but owing to containing a large amount of suspensions in municipal sewage and industrial wastewater, its circulation is utilized to be again open type, suspension in heat exchanger and impurity are in cumulative process rapidly, blocking is extremely serious with soft dirty pollution problem, very easily block heat exchanger, heat exchange efficiency reduces greatly, have a strong impact on the heat transfer effect of heat-exchange system, so plate cleaning often will be dismantled, cleaning process is more loaded down with trivial details, , the clean and maintenance cycle is short, operation element amount is large, and add production cost, and sewage or industrial wastewater are done filtration treatment by existing sewage heat change system employing, exploitation filtering technique and equipment, recycling heat exchanger carries out heat exchange, although solve blockage problem like this, but also make system process quite complicated, cost of investment improves greatly.
A kind of automatic inverse flushing native sullage plate heat exchanger (utility model application 200820074148.X) is proposed in prior art, its feature is that sewage enters, outlet and clean water enter, outlet connects one group of reverse circulated loop respectively, sewage enters, outlet is connected with differential pressure pickup, when sheet surface fouling makes sewage resistance increase, sewage is caused to enter, between outlet pipe, pressure reduction increases, utilize and enter with sewage, the differential pressure pickup that outlet pipe connects reaches backwash object, sheet surface fouling is rinsed, but this method can only make sheet surface fouling be rinsed, the stopping state that other impurity in sewage and dirt cause cannot be avoided.
Propose one in prior art and exempt to unpick and wash centrifugal sewage heat exchanger (application for a patent for invention number 201110191631.2), its enclosure interior is provided with double-layer spiral runner, double-layer spiral runner upper, lower port is communicated with intermediary water inlet with intermediary water out respectively, the neighboring of double-layer spiral runner is fixedly connected with the inwall of housing, the inner periphery of double-layer spiral runner is fixedly connected with tube wall, the cavity formed between double-layer spiral runner adjoining outer walls forms sewage runner, sewage runner upper, lower two ends are communicated with outlet of sewer with sewage inlet port respectively, its feature utilizes centrifugal force make dirt be difficult to precipitate and rest on the surface of intermediary's water heat exchange, widen sewage runner by increasing simultaneously, larger object or particle and suspension can smooth and easyly be passed through, thus the heat exchanger dismounting problem avoided because blocking and dirt dirt cause, but this heat exchanger structure is more complicated, volume is large, cost of investment is high, use power consumption is large, uneconomical applicable.
Utility model content
The utility model is intended to solve the problem, thus provide a kind of dirty impurities in water and dirt can be avoided to cause blocking and pollution, reduction heat exchanger dismounting frequency, improve service life, structure is simple, cost of investment is low sewage plate type heat exchanger.
The utility model solves described problem, and the technical scheme of employing is:
A kind of sewage plate type heat exchanger, comprise framework, plate, the clamping plate of framework is provided with clean water import and export and sewage import and export, screen pipe is provided with in the pipeline of wastewater inlet, the clamping plate of the wastewater inlet pipeline other end is provided with one with the perforate of welding adapter and flange, the flange of perforate is provided with blind plate.
Adopt the utility model of technique scheme, compared with prior art, its outstanding feature is:
1. the blocking that the dirty impurities in water of sewage plate type heat exchanger and dirt can be avoided to cause and pollution, reduce the dismounting frequency of heat exchanger, improve service life and heat exchange efficiency.
2. structure is simple, and volume is little, cost of investment is low.
As preferably, the utility model further technical scheme is:
Plate is fat pipe structure, increases circulation area, avoids runner to block.
Plate is one time punching molded structure, and structure is simple, and cost of investment is low.
Sheet surface is coated with corrosion-inhibiting coating, can effectively avoid plate to corrode, and improves service life.
Screen pipe adopts sheet material with holes to roll or select silk screen to roll.
