Sewage source heat pump technology characteristics and operation mechanism
Sewage source heat pump heat pump is the main technical principles of the operation mechanism, the sewage in the heat or cold transferred to buildings. Can be divided into three energy transfer process:
The first process : unit of medium in the evaporator to absorb heat medium evaporation, evaporation temperature of 3 DEG C, poly bag supplierat 10 DEG C of medium water in the evaporator by heat transfer medium, and the heat is released, and to the medium, medium absorbs heat evaporation.
Second process: set oneself medium circulation, evaporation of the gas compressor suction and compression, into high temperature, high pressure gas, into the condenser, heat transfer process to the condenser, and the condenser is connected with the terminal system.
Third process: unit under high temperature and high pressure, medium enters the condenser, heat, and water for heat exchange, will realize in the evaporator absorbs heat and input power sum output to the heating system of process water, heating system water heat release to the room, achieve the purpose of heating. In the whole process, unit energy input output ratio can reach a maximum of 4.5, whereby the motor input power is 1kcal, the energy is 4.5kcal terminal system. In the whole process of a small quantity of electric power consumption, great use sewage energy, thereby achieving the purpose of saving energy, refrigeration process for the thermal process of inverse process.
Technical characteristics
Beijing rainbow benefit of energy science and technology limited company independent research and development of sewage source heat pump system is the key to take the heat removal process to prevent bad water heat exchange equipment congestion and pollution. Sewage in the presence of a large number of large scale debris, such as plastic bags, leaves, cause the equipment and pipeline jam pollution, the traditional means of filtration and machinery grille can dispose of these objects, but the actual inoperable, involves covering, cleaning, impurity transport and the surrounding environmental pollution problemsmake plastic bageven with the most simple water treatment process, the processing cost but also greatly higher than the pump from the water heating and cooling of the value, but also in water treatment process also covering problem. This gave the city sewage source heat pump has brought extinction catastrophe, it is also the technical delay development problem. Therefore, to solve the bad quality of heat transfer equipment and pipeline jam and pollution problems of the traditional sense of the water treatment is not feasible. As a result of sewage water quality characteristics, and the other water source heat pump technology compared with its two characteristics, is also the key technology of this system.
( 1) the application process and equipment.
Sewage source heat pump intelligent sewage control machine ( referred to as intelligent anti trimming machine ) filter face their rotation, at any time have some filtering surface located in the filtering work area, sewage is specified in diameter above the solid, suspended solids were filtering surface interception, which contains the size of the suspended solids to sewage heat exchanger non blocking heat transfer device. Another portion is located in the hydraulic recoil filter surface area. In the filter surface to rotate within a week, each with a filtering hole has a part time in the filter working region to exercise a filtering function, another part of the backwash zone by backwashing, to restore the function of filtering. Sewage through the filtering to heat exchanger heat transfer without clogging, after heat exchange to prevent sewage sewage machine back flush area on the filtering surface of backwashing, and the backwashing dirt all away side by side back to the sewers. To successfully solve the city sewage utilization in large debris caused by equipment and pipeline plugging problem of pollution. The technology and equipment, can ensure the city sewage heat exchanger without clogging to run for a long time, so that the large-scale application of city sewage as cold and heat source of heat pumps become reality.
( 2) sewage heat exchanger.
Despite the removal of sewage in some of the larger debris, but miniature sediment and fibrous dirt still exists in a large amount, actually may not take sewage treatment process, because the processing fees are extracted heat value and high times. Due to the micro fibrous sediment and dirt on the flow and heat transfer has great influence, therefore, Beijing rainbow benefit of energy science and technology limited production of sewage heat exchanger has a special process. My company at home and abroad is the only one in the original sewage source heat pump heating and air conditioning professional enterprises, has experts agree that the world's first, level of technology is a leading international level. The" sewage intelligent self cleaning anti blocking heat collector" the process and technology has been the achievement of national science and technology innovation award.
Practice has proved, the technology and equipment, can ensure the city sewage heat exchanger without clogging to run for a long time, so that the city sewage used as sewage source heat pump cold heat source to become a reality. The technological achievements after years of in-depth theoretical research and a number of engineering practice, has become increasingly mature and improve; already in energy saving, water recycling, Offshore company environmental protection three aspects have extensive, far-reaching influence.
