1, heat pipe waste heat recovery
Heat pipe waste heat recovery is the use of heat pipe heat transfer characteristics of high efficiency and its environmental adaptability of heat transfer devices, mainly used in industrial energy saving field, can be widely recovered in the gaseous, liquid, solid media in the waste heat source. According to the state of hot fluid and cold fluid, heat pipe waste heat recovery device can be divided into: gas-gas type, gas-vapor type, gas-liquid type, liquid-liquid type, liquid-gas type. According to the structural form of the recycler can be divided into: integral, separated and combined.
2, between the wall heat exchanger
Heat exchanger is the chemical industry, petroleum, power, food and many other industrial sectors of the general equipment, occupies an important position in the production. In chemical production heat exchanger can be used as a heater, cooler, condenser, evaporator and reboiler, etc., more widely used. There are many types of heat exchangers, but according to the principle of heat exchange of cold and hot fluids and the way basically can be divided into three major categories, namely: between the wall, mixed and thermal storage. In the three types of heat exchangers, between the wall type heat exchanger is the most widely used. Common wall heat exchanger such as: cooling tower (or cold water tower), gas scrubber tower (or scrubber tower), jet heat exchanger, mixed condenser.
3, regenerative heat exchanger
Regenerative heat exchanger is used for regenerative heat transfer equipment, generally used in the media mixing requirements are relatively low occasions. Heat exchanger is loaded with solid filler to store heat. Generally use refractory bricks and other fire lattice (sometimes with metal waveform band, etc.).
Storage heat transfer in two stages. The first stage, the hot gas through the fire lattice, the heat will be transferred to the fire lattice and storage. In the second stage, the cold gas passes through the fire lattice and is heated by the heat stored in the fire lattice. These two stages alternate. Usually use two heat accumulators alternately, that is, when the hot gas into a device, the cold gas into another device. Commonly used in the metallurgical industry, such as the heat storage chamber of a steelmaking flat furnace. Also used in the chemical industry, such as the air preheater or combustion chamber in a gas furnace, and the regenerative cracking furnace in a man-made oil plant.
4, energy-saving ceramic heat exchanger
Ceramic heat exchanger is a new type of heat exchanger, in the high-temperature or corrosive environment to replace the traditional metal heat exchanger. With its special material - SIC quality, the kiln originally used cold air into hot air to achieve the purpose of waste heat recovery. As it can be used for a long time in concentrated sulfuric acid, hydrochloric acid and alkaline gas and liquid for a long time. Antioxidant, heat shock resistance, high temperature strength, good antioxidant performance, long service life. Heat tapping industrial kiln. The exchanged hot air as combustion air sent into the kiln and gas to form a mixture for combustion, can save 25%-45%, or even more energy.
5, jet mixing heater
Jet mixing heater is the application of jet technology in the field of heat transfer, jet mixing heater is through the direct mixing of steam and water two-phase fluid to produce hot water equipment. Jet mixing heater has high transfer efficiency, low noise (up to 65dB or less), small size, simple installation, reliable operation and low investment. The use of jet mixing heater to recover waste heat from power plants, paper mills, chemical plants, heating circulating water
Jet mixing heater is particularly suitable for use in small and medium-sized heating systems with a heating area of less than 60,000 square meters, replacing the function of the surface heater. Depending on the conditions of the heat source, the temperature of the heated water can be increased by 20℃ to 50℃. If the temperature rise of the water is required to be larger, two-stage jet hybrid heaters can also be used in series arrangement.
