Abstract
The utility model discloses a plate heat exchanger, belongs to heat exchange equipment, and particularly relates to a plate heat exchanger with a descaling device. The plate heat exchanger comprises a heating medium inlet, a heating medium outlet, a coolant inlet and a coolant outlet, wherein the heating medium inlet, the heating medium outlet, the coolant inlet and the coolant outlet are mounted on a fixed compressing plate. The plate heat exchanger is characterized in that the heating medium inlet is provided with a heating medium descaling electromagnetic pole perpendicular to a water inlet pipe, the coolant inlet is provided with a coolant descaling electromagnetic pole perpendicular to the water inlet pipe, the heating medium descaling electromagnetic pole and the coolant descaling electromagnetic pole are both connected with a various frequency current generator through wires, and the various frequency current generator is installed on the middle portion of the fixed compressing plate. The plate heat exchanger has the advantages that the descaling electromagnetic poles are directly installed on the water inlet of the plate heat exchanger, the descaling device is combined with the heat exchanger into a whole, descaling processing can be carried out on water entering the plate heat exchanger, heat exchange efficiency can be improved, and service life of the plate heat exchanger is prolonged. Compared with the fact that the descaling device is installed independently outside the plate heat exchanger, the plate heat exchanger has the advantages of being low in manufacturing cost and small in size, and saving an installation area.
Description
Technical field
The utility model belongs to heat-exchange apparatus, and the plate type heat exchanger of apparatus for eliminating sludge particularly is housed.
Background technology
Plate type heat exchanger is a kind of new type high efficient heat exchanger that is formed by a series of sheet metal closed assemblies with certain bellows-shaped.Form the thin rectangular shape passage between the various plates, carry out exchange heat by plate.Plate type heat exchanger is the ideal equipment that liquid-liquid, liquid-vapour carry out heat exchange.It has that heat exchange efficiency height, heat loss are little, advantages of compact and light structure, floor space are little, install clean make things convenient for, be widely used, characteristics such as long service life.Under the uniform pressure damaed cordition, its heat transfer coefficient is than the high 3-5 of pipe heat exchanger times, and floor space is 1/3rd of pipe heat exchanger, and heat recovery rate can be up to more than 90%.It is exactly that the easy fouling of the water capacity results in blockage that but there is the drawback of a maximum in existing plate type heat exchanger, if stopping up, heat exchanger may directly influence the heat exchange effect, serious must take cleaning apart, cleaning as this equipment of plate type heat exchanger is very hard, also wasting time very, if in heating season, fouling of heat exchangers stops up and the words of cleaning, must stop heating, so most of user can not accept.In order to solve the problem of the easy fouling of plate type heat exchanger, the employing that has at the plate type heat exchanger water inlet end independently apparatus for eliminating sludge is installed, though can reduce the fouling blockage problem, apparatus for eliminating sludge takes up an area of big, has influenced the performance of the little advantage of plate type heat exchanger volume.
The utility model content
In order to overcome the easy fouling obstruction of existing plate type heat exchanger or the big deficiency of external apparatus for eliminating sludge floor space, the utility model provides a kind of plate type heat exchanger, this plate type heat exchanger has realized that scale removal is heat-exchange integrated, both can avoid fouling to stop up, not increase volume and the floor space of plate type heat exchanger again.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of plate type heat exchanger, comprise that the heating agent that is installed on the fixed pressure plate is imported and exported, refrigerant is imported and exported, it is characterized in that: the heating agent scale removal electromagnetic pole vertical with water inlet pipe is installed in the described heating agent import, the refrigerant scale removal electromagnetic pole vertical with water inlet pipe is installed in the described refrigerant import, heating agent scale removal electrode all is connected with the frequency conversion current feedback circuit by lead with refrigerant scale removal electrode, and the frequency conversion current feedback circuit is installed in the middle part of fixed pressure plate.
Because the utility model is installed the electron ion rod at the heating agent of plate type heat exchanger and the water inlet of refrigerant respectively, make and enter heat exchanger and get hydrone under the effect of frequency-conversion electromagnetic field, the associative key that makes original big association body state water is interrupted by the degree of depth and is dissociated into active very strong unimolecule or the water of little association state, thereby physical arrangement and the characteristic of water have been changed, strengthened the polarity of hydrone, increased the polar moment of hydrone, improve the hydratability of hydrone to dirty components of one-tenth such as calcium ions and magnesium ions, carbanions, played the effect that stops incrustation scale to form.And make original incrustation scale crystallization become soft, come off, dissolve, and discharge through drain filter, reach the scale removal purpose.
The beneficial effects of the utility model are that the scale removal electromagnetic pole is directly installed on the heating agent of plate type heat exchanger and the water inlet of refrigerant, realized variable-frequency electromagnetic descaling equipment and heat exchanger package are integrated, can carry out the formation that the scale removal processing can reduce incrustation scale to entering plate type heat exchanger water, can also make original incrustation scale crystallization become soft, come off, dissolving, discharge through drain filter, can improve heat exchange efficiency, increase the service life of plate type heat exchanger, descaling equipment is installed outside plate type heat exchanger more separately, and to have cost low, volume is little, save advantages such as erection space.
