(1) Principle of waste heat recovery machine (one heat) Principle of direct thermal, room temperature water first through the air, water heat exchanger, the air temperature was lowered to room temperature, water exchange after re-entering the oil, water heat exchanger is the excess oil to maximize the absorption and utilization of capacity by adjusting the compressor run oil temperature control between 70 ~ 95 ℃, the system uses BESTDN microcomputer control, real-time monitoring and protection of the air compressor running, 100 % ensure the normal operation of the air compressor, the system is running, it passed its own pressure water pipe network, so the water can reach places without the pump running. Waste heat recovery machine uses direct thermal is greater than 1 ℃ cold water is directly heated to between 55 ~ 90 ℃. Since the exchange with compressor oil and compressed air is room temperature water, so oil and gas temperature is controlled filling, so as to achieve the purpose of controlling the cooling system, maximize heat recovery and reduce system power consumption. Features 1, exactly matching the compressor operating conditions to achieve the best energy-saving effect. 2, the security control of air compressor cooling system, heat recovery maximized. 3, oil and gas dual recycling, energy efficiency, COP up to 88%. Energy conservation principle corrugated plate design with a high thermal conductivity of the film as the target number of different corrugated plates are inverted a complex flow path, so that rotation of three-dimensional fluid flow within the flow channel, strong turbulence can occur at low Reynolds numbers while turbulence should have self-cleaning and prevents dirt generation, cold and hot fluid whole countercurrent flow, logarithmic mean temperature difference correction system is small, the hot and cold fluid flow in the plate heat exchanger parallel to the heat transfer surface, no bypass, thus making the end plate heat exchanger temperature difference is small, water heat exchanger to reach 1 ℃, compact structure, small size, the heat loss to a minimum. (2) First, the principle of a heat recovery air compressors, compressor works as follows: The motor drives the screw rotates, the air through the filter, is sucked into the high-pressure screw compressor compressed air and circulating oil are mixed to form a high pressure Oil temperature gas mixture into the oil separator. Oil and gas mixture is separated into oil, gas and air after which the compressed air through the cooler after the heat supply to the users; and the cycle of oil and gas are separated in the oil and gas separator, condensed into liquid, and then by the former Cooler and filters , back to the compressor to complete a cycle. 2, the process of compressor operation: air compressor design oil temperature is generally 50-60 ℃, the exhaust gas temperature when the actual operation is often between 80-90 ℃, higher exhaust temperature vane compressor . High exhaust gas temperatures will lead to more oil in the gas phase, increasing the difficulty of separating the oil and gas, reducing the service life of the lubricant, the rear end of the cooling apparatus to increase compliance and reduce the overall pot life of the device. In addition to the heat generated by mechanical friction under load state, the compressor in the compressed gas will be converted mechanical energy into heat, in fact, the air compressor is running, only about 20-30% of the input energy into the air potential (ie: The atmospheric air into high-pressure air), and the remaining most of the energy is discharged through the air compressor cooling system into the air, it is wasted. In the factory, the air compressor running time more than five years, the main cost is the energy, mind, compressor waste heat utilization has been growing attention to (the cost structure shown below). 3, heat recovery unit work process: In this context, air compressor heat hot water unit came into being, our equipment can be high-temperature cycle oil (and hot compressed gas) access within the thermal water heaters, air process running in the heat generated by the fully absorbed, the water is heated. In this process, a compressor, a heat medium oil and air to be cooled, and the cold water is the medium to be heated. Compressor temperature drops, extend the life of the machine, to improve the gas production; oil and compressed air temperature drops, the rear end of the cooling apparatus can reduce burden; and after the water is heated to the set temperature, the thermal energy from the hot water unit via the hot water piping system enterprise required to place. The following is a schematic diagram for various uses: Second, the typical application connection diagram is the classical factory air compressor waste heat recovery scheme, no power, no burning oil, zero emissions, completely free of water supply! Third, the advantages of a compressor heat recovery, energy efficient, significantly benefit the entire hot water units except two small power pump occasionally run outside, do not consume any energy, no power, no burning oil, zero energy consumption. 2, water protection and longer life due to the access device made quite a compressor cooling project, the system at the same time free to produce hot water also can increase gas production, reduce the oil temperature, reducing the load of the cooling system, prolong empty press life. 3, throughout the day, anywhere since the heat hot water unit using heat generated by the compressor is running, so the hot water produced entirely unaffected by weather, as long as the production progress, to ensure all-weather hot water supply. 4, quality leadership, stable and durable compressor heat exchanger hot water unit core components without any moving parts, under normal circumstances, the service life of up to 8--10 years, strict selection and quality control to ensure the stability and durability of the system. 5, safe, reliable, safe and secure energy water heaters in the design fully comply with the principle of separation of water, to prevent the electrocution, poisoning, explosion and other safety hazards using other heating devices may occur. At the same time, robust construction and scientific design to ensure the safety of air compressor systems, compressor does not transform the original system, without any adverse effects. 6, easy to install, simple heat hot water unit modular design, simple construction and easy operation. 7, highly intelligent, saving labor of the unit complete system intelligent control, temperature control, oil detection, automatic replenishment, automatic bottled water, intelligent shutdown and other actions all through the process is complete, no staff on duty. 8, the economy is strong, economical tool according to the customer's existing hot water usage, in general 6-12 months can recover the full investment. 9, environmental protection, energy saving hot water unit to fully utilize the air compressor waste heat to produce hot water, no pollution, no noise, no emissions, no smoke, no oil. 10, sincere service, Houguwuyou entire system one-year warranty, the core of the heat exchanger two-year warranty and lifetime maintenance and 24-hour technical support.
