Several working forms of waste heat recovery equipment of Fengxin Technology Factory

Heat pipe waste heat recovery device

 Heat pipe waste heat recovery device is a heat exchange device made by using the high efficiency heat transfer characteristics of heat pipe and its environmental adaptability. It is mainly used in the field of industrial energy saving, and can widely recover the waste heat sources in gaseous, liquid and solid media. According to the state of hot fluid and cold fluid, the heat pipe waste heat recovery device can be divided into: gas gas type, gas steam type, gas liquid type, liquid liquid gas type. According to the structure of the recycler, it can be divided into: integral type, separate type and combined type.

Wall to wall heat exchanger

The heat exchanger of the waste heat recovery factory is the general equipment of chemical, petroleum, power, food and many other industrial departments, which plays an important role in the production. In the chemical production, the heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., which is more widely used. There are many kinds of heat exchanger, but according to the principle and method of heat exchange of cold and hot fluid, it can be basically divided into three categories: wall type, hybrid type and regenerative type. Among the three types of heat exchanger, wall to wall heat exchanger is the most widely used. Common wall type heat exchanger such as: cooling tower (or cold water tower), gas washing tower (or washing tower), jet heat exchanger, hybrid condenser.

Regenerative heat exchanger

The regenerative heat exchanger is used for the equipment of regenerative heat exchange, and it is generally used in the occasions with low requirements for medium mixing. The heat exchanger is filled with solid filler to store heat. Generally, fire grids are built with refractory bricks (sometimes with metal wave belts, etc.).

The regenerative heat transfer is carried out in two stages. In the first stage, the hot gas passes through the fire lattice and transmits the heat to the fire lattice for storage. In the second stage, the cold gas is heated by the heat stored in the fire lattice through the fire lattice. The two stages alternate. Generally, two regenerators are used alternately, that is, when the hot gas enters one, the cold gas enters the other.

It is often used in metallurgical industry, such as regenerator of open hearth furnace. It is also used in chemical industry, such as air preheater or combustion chamber in gas furnace and regenerative cracking furnace in artificial oil plant.

Energy saving ceramic heat exchanger

Ceramic heat exchanger in Jinan ventilation equipment is a new type of heat exchanger, which replaces the traditional metal heat exchanger in high temperature or corrosion environment. With its special material SiC, the cold air used in the kiln is changed into hot air to achieve the purpose of waste heat recovery. It can be used in concentrated sulfuric acid, hydrochloric acid, basic gas and liquid for a long time. Oxidation resistance, heat shock resistance, high temperature strength, good oxidation resistance and long service life. Hot tapping industrial furnace. It can save 25% - 45% energy and even more energy if the hot air is sent to the kiln as combustion supporting air to form a mixture with gas for combustion.

Jet mixing heater

Jet mixing heater is the application of jet technology in the field of heat transfer. Jet mixing heater is a device that produces hot water by direct mixing of steam and water two-phase fluid. The jet mixing heater has the advantages of high transfer efficiency, low noise (up to 65dB), small volume, simple installation, reliable operation and low investment. Recovery of waste heat from power plant, paper mill and chemical plant by jet mixed heater, heating circulating water

Jet hybrid heater is especially suitable for small and medium-sized heating systems with heating area of no more than 60000 square meters. According to the different conditions of heat source, the temperature of heating water can be increased by 20 ℃ ~ 50 ℃. If the temperature rise of water is required to be large, the two-stage jet mixing heater can also be used in series.
