Our steam injection system has reliable performance and low maintenance requirements.
Jet vacuum system is used to create and maintain vacuum in polyester and nylon production equipment.
Steam ejector is a kind of vacuum equipment, which is the application of jet technology in the field of heat transfer. The steam ejector has the characteristics of simple structure, no moving parts, stable and reliable operation, large pumping capacity, and can extract water vapor, dust, flammable, explosive and corrosive gases.
Working principle: the high-pressure power steam enters the suction chamber at several times the speed of sound through the Laval nozzle, forming a low-pressure area in the suction chamber, and the low-pressure suction fluid is carried into the suction chamber by the high-pressure power steam; in the mixing section of the diffuser, the power steam decelerates continuously, and the extracted gas accelerates continuously to exchange momentum and energy and mix gradually; In the throat of the diffuser, the power steam and the extracted gas are completely mixed evenly, and the speed reaches the same; in the diffuser section, the speed gradually decreases, and the pressure gradually increases, and the kinetic energy is converted into enough pressure energy to achieve the outlet pressure discharge.
Suction Range: The steam ejector is customized according to different working conditions, with an extraction volume of 0 to several hundred thousand cubic meters.
Material: Carbon steel, stainless steel, graphite and other non-metallic materials can be selected according to different working conditions.
Steam Ejector Vacuum System
The steam injection system is composed of steam ejector, condenser and valve fittings. General steam injection system mainly includes: direct condensation steam injection system and indirect condensation steam injection system.
Jet vacuum pumps are usually driven by steam. Steam is easy to obtain in industry and has been proved to be a good power medium. When the steam in the jet vacuum pump condenses, the condensate must be regarded as waste liquid in some cases.
If the product steam generated in the production process is used as the power medium of the jet pump, this situation can be avoided. The power steam condensate can be further used in production or re evaporated and used as power medium again. The product steam driven jet pump is also used under the condition that no water can enter into the system.
The function of product steam driven jet vacuum pump is no different from that of steam driven jet vacuum pump, so it provides the same basic advantages. In addition, the energy consumption requirement is lower than that of steam driven jet vacuum pump to a certain extent, because the evaporation of organic steam requires less heat.
