【正文】 uid absorption gas mixture of some ponents, in addition to the net gas in the dust, gas, wet or dry. But its most extensive use is a cooling gas, and the cooling liquid used mostly to water. Air conditioning engineering is widely used in the spray chamber, can be regarded as a special form of it. Spray chamber not only can like gas washing tower for air cooling, but also can carry on the heating treatment. However, it also has the high water quality requirements, large occupation area, such as the shortings of many pump energy consumption: so, present in the general construction, the spray chamber is not usually used or only as humidification equipment use. However, in order to regulate the humidity for the primary purpose of the textile factory, cigarette factory is still widely used!( 3) jet heat exchangerIn this device, the high pressure fluid from the nozzle, forming a high velocity, low pressure fluid is introduced into the mixing chamber and jet direct contact heat transfer, and feeding into a diffusion tube, the diffusion tube exit to achieve the same pressure and temperature to the user.( 4) mixing condenserThe device is usually the water and steam in direct contact method to make steam condensate.The regenerative heat exchanger heat storage type heat exchanger used for regenerative heat exchange equipment. With solid filler, used to store heat. General refractory brick brick fire plaid ( sometimes with metal wave band ). Heat transfer in two stages. The first stage, the hot gas through the lattice, the heat is transferred to the fire and save up lattice. The second stage, cold gas through the lattice, lattice savings by fire heat emitted by heating. The two phase alternating. Usually with two regenerator used alternately, whereby when the hot gas into a reactor, cold gas into another device. Commonly used in the metallurgical industry, such as the open hearth furnace regenerator. Also used in chemical industry, such as gas furnace air preheater or bustion chamber, synthetic oil plants in the heat accumulating type cracking furnace.The regenerative heat exchanger is generally used on medium mixed with low requirements.Ceramic ceramic heat exchanger heat exchanger is a kind of new type high temperature heat energy recovery device, main ponent is silicon carbide, can be widely used in metallurgy, machinery, building materials, chemical industry, recycling all kinds of industrial furnace directly discharged 8501400 high temperature flue gas waste heat, in order to obtain high temperature bustion air or gas.Research into the device to the heat transfer element material is a new type silicon carbide ceramic works, it is resistant to high temperature and thermal shock performance, from 1000 degrees C air cooled to room temperature, repeated 50 times over the cracks do not occur。s version of the GMP launched, plate will gradually withdraw from the food, beverage, pharmaceutical and other highlevel health industry.Shell and tube type heat exchanger tube shell type heat exchanger ( also known as the tube ) is a shell and tube heat exchanger mainly prises a shell, pipe, tube plate and the head and other parts, shell were round, with internal parallel bundles or spiral pipe, both ends of the pipe bundle, fixed on the tube plate. In shell and tube heat exchanger for heat exchange of the two fluids, a kind of flows in tube, the trip called tube。 however, the heating surface by the container wall, heat transfer coefficient is not high. In order to improve the heat transfer coefficient and the kettle liquid is heated evenly, the kettle stirrer. When the jacket cooling water is injected into or no phase change heating agent, also in the clamping sleeve arranged helical baffles or other additional turbulent measures, in order to improve the jacket side heat transfer coefficient heat transfer surface. As a plement deficiency, also can be in the interior of the autoclave fitted snake tube. A clamping sleeve type heat exchanger used in the reaction process of heating and cooling.Submerged coil heat exchanger in this heat exchanger is the metal pipe winding into various and container which is adapted to the shape, and immersed in a liquid contained within the container. The snake tube heat exchanger has the advantages of simple structure, can bear high pressure, corrosionresistant materials available。 the upper and lower guide rod, connection on the frame plate and between the uprights, used to support and to the pressure plate and the heat transfer piece guide。 a plurality of tie rod bolt, used to intensify the frame plate and the pressure plate。The pipe corrosion, together with the shell scrap, the service life of the equipment is low。The difference in temperature, easy to produce, the tube plate and the tube head is easy to produce thermal stress damage。Thirdly, no inner leakage。 U shape tube heat excha
