Abstract
The invention discloses a heat energy exchange unit, which comprises a first heat exchanger, a second heat exchanger, wherein the shell side or pipe side of the first heat exchanger is connected with a cold and heat circulating water pipe of a production device; the shell side or pipe side of the second heat exchanger is connected with a cold and heat water pipe of a heat utilization device; the pipe sides or shell sides of the first and second heat exchangers are communicated through a compression pipe with a compressor and an expansion pipe with an expansion valve; and working medium is filled in the communicated pipe sides or shell sides. The heat energy exchange unit has the following advantages that: 1, the heat is fully utilized, the steam consumption is reduced, and a great deal of fuel cost is saved; 2, a cooling tower is eliminated, so water loss caused by sprayed water evaporation and drifting is reduced, the waste of water resource is avoided, and heat radiation pollution to the air is reduced; and 3, enclosed circulation is adopted, the water loss is reduced, and the saline matter is difficult to deposit. Meanwhile, oxygen, microorganisms and nutrient required by microorganisms are difficult to enter a circulating water system, so the water treatment cost is reduced and the service life of the heat exchange equipment is prolonged.
Description
One, technical field
The invention belongs to energy recovery and utilize technical field, be specifically related to a kind of heat energy exchange unit.
Two, background technology
In manufacturing enterprises such as oil, chemical industry, power plant and steel mill, usually the application cycle water system is that process units cools, promptly for providing cooling water, process units lowers the temperature by the circulating water pipe, by the circulating hot water pipe heated cooling water is sent into cooling tower again and lower the temperature, at last by sending process units again back to after the water pump pressurization.There is following weak point in this kind method: 1, a large amount of heat energy are discharged in the air, waste, and environment is polluted.2, a large amount of water vapour tower that is cooled evaporates, and not only causes the waste of water resource, and produces a large amount of salts and be deposited in the circulation, has increased cost of water treatment.3, because to have adopted cooling tower, circulation be open, thereby the required nutrient of a large amount of oxygen, microorganism and microorganism can enter in the circulation, caused the deterioration of water quality, also increased cost of water treatment.
Three, summary of the invention
The purpose of this invention is to provide a kind of heat energy exchange unit, to overcome the many deficiencies in the present technology.
For achieving the above object, the technical solution used in the present invention is: this unit comprises first and second two heat exchangers, is characterized in: the shell side of first heat exchanger or tube side link to each other with the hot and cold circulating water pipe of process units; The shell side of second heat exchanger or tube side link to each other with hot and cold water pipe with thermic devices; Between the tube side or shell side of first and second heat exchanger, compressed pipe through having compressor and the expansion tube that has an expansion valve communicate, and in tube side that communicates or the shell side working medium are housed.
Adopt said structure, working medium is under the expansion valve effect, and gasification heat absorption in the tube side of first heat exchanger or journey will siphon away from the heat that the process units circulating hot water pipe sends into the hot water in shell side or the tube side; The working medium that has heat is under the effect of compressor, and the heat release of liquefying in the tube side of second heat exchanger or shell side enters cold water in shell side or the tube side with heat transferred from cold water pipe, and the hot water that produces after the heat exchange is supplied with by hot-water line and used with thermic devices.Because heat transfer process is to force to carry out in the physical phase transition process of working medium, more traditional parallel heat exchange mode, has higher heat exchange ratio, improved heat exchange efficiency and heat exchange ratio, when having realized high efficient heat exchanging, also have following advantage: 1, heat is fully recycled, and has reduced steam consumption, save a large amount of fuel costs, increased economic benefit.2, owing to cancelled cooling tower, reduce the moisture loss of being brought because of trickle evaporation and drift, thereby avoided the waste of water resource, reduced heat radiation pollution to air.3, because recirculated water has been realized sealing and circulating, reduced scattering and disappearing of moisture, salt is difficult for being deposited in the circulation.Simultaneously, the required nutrient of oxygen, microorganism and microorganism also is difficult to enter in the circulation, thereby has reduced cost of water treatment, prolongs the service life of heat transmission equipment.
