Price of electric heating pure steam generator

Principle of pure steam generator

Pure steam generator is currently one of the important equipment used in sterilization cabinets, bioreactors (tank equipment), pipeline systems (online sterilization), filters, and other applications. Ultra pure without pyrogen, the product meets the requirements for injection water in the current US Pharmacopoeia, European Pharmacopoeia, Japanese Pharmacopoeia, and Chinese Pharmacopoeia. Design and manufacture strictly in accordance with pressure vessel specifications. Can be used for process production lines in industries such as food, pharmaceuticals, and biotechnology.

Technical Features

Structural material: All parts in contact with raw water, pure steam, and injection water are made of 316L material.

• Electrochemical polishing: Electrochemical polishing of stainless steel surface to ensure the quality of production injection water and improve the service life of equipment.

• Double tube plate design: The external preheater, condenser, and high-efficiency evaporator are all designed with double tube plates, which comply with cGMP requirements and effectively eliminate the possibility of low hygiene level medium pollution in the system.

• All hot surfaces are insulated and surrounded by a 304 stainless steel shell on the outside.

• There are no moving parts on the device, making it relatively quiet, safe, and reliable to operate.

• Reliable PLC control, standardized program.

• Complete file verification and service system.

• Easy to operate and maintain.

• Control system: Adopting PLC automatic control technology to meet different control requirements of customers. From the basic assessment and distribution of pure steam quality, to more advanced methods such as continuous adjustment of various media, linkage with storage systems, hierarchical password control, and even control of evaporation rate changes, it can be said to be meticulous.

• Factory testing of complete machine performance: In the complete machine testing workshop, simulate the actual working environment according to the determined program and conduct complete machine testing.

The workflow of PSG-S type is as follows: raw water enters the separator and evaporator tube through the feed pump (the two are connected), and the liquid level is controlled by a liquid level sensor and PLC connection. Industrial steam enters the shell side of the evaporator to heat the raw water in the tube side to the evaporation temperature, and the raw water is converted into steam. This steam separates small droplets back into the raw water through gravity at low speed and high stroke of the separator, and re evaporates. The steam becomes pure steam and enters the top of the separator through a specially designed clean wire mesh device. Pure steam enters various distribution systems and usage points through the output pipeline.

The regulation of industrial steam allows the pressure of pure steam to be set through a program according to the production process requirements and can be stably maintained at the pressure value set by the user. During the evaporation process of raw water, the supply of raw water is controlled by the liquid level to maintain the liquid level at a normal level. For concentrated water, intermittent discharge can be set in the program.

Principle of pure steam generator

The workflow of PSG-G type is as follows: the raw water is heated by industrial steam in the first effect preheater, and after entering the second effect preheater, it is further heated by industrial steam condensate; Then, after entering the top of the evaporator through a water separation device, it is evenly distributed into the evaporator tubes, forming a thin film like water flow inside the evaporator tubes; These water flows are quickly evaporated due to their thinness, producing secondary steam; The raw water that has not been evaporated is discharged outside the machine. The raw water that has been evaporated is now secondary steam, which continues to spiral upwards in the evaporator, passes through the steam water separation device, and is output as pure steam from the pure steam outlet. Industrial steam is condensed into industrial steam condensate after being absorbed by the raw water in the evaporator, which serves as the heating source for the preheater. After preheating the raw water, it is discharged outside the machine through the outlet of the non condensable water in the preheater. Trace pure steam is collected by a condenser sampler and undergoes heat exchange with cooling water to become distilled water; Through online detection of conductivity, determine whether pure steam is qualified.

The secondary steam converted from raw water is clean steam, which undergoes three separation processes: after entering the evaporator at the beginning, it flows down along the tubes and evaporates at the same time, which is the * separation process; The evaporated raw water (secondary steam) is turned back 180 degrees at the lower end of the evaporator, and impurities are separated to the lower part by gravity, which is the second separation; The evaporated raw water, i.e. secondary steam, continues to spiral upwards in the evaporator and reaches the special separation device in the middle and upper parts for the third separation.

There is a portion of gas in the raw water that cannot condense into water, called non condensable gas. Depending on the degree of automation control, a continuous non condensable gas discharge device is installed at the top of the evaporator for this non condensable gas.

Difference between S-type and G-type

The forms of separation devices are different: the S-type adopts a wire mesh separation method, while the G-type adopts a spiral plate separation method.

The range of product specifications and models varies: the S-type performs well in larger models, as detailed in the product selection table.

The heating sources used for preheaters are different: the S-type has no preheater, while the G-type has a preheater.
