The feed water is delivered to the side of the pipe that removes the contaminated column and heat exchanger through a feed pump, and the liquid level is controlled by a level gauge. After the industrial steam or heated water enters the heat exchanger, the raw water is heated to the evaporation temperature. And a strong thermal cycle is formed inside the two cylinders. Pure steam is produced in the evaporator (excluding the contaminated column). The low velocity of the steam and the height of the cylinder will remove any water droplets that may be impure under gravity. Through a pneumatic adjustment of the opening degree of the industrial steam inlet valve, the pure steam pressure can be constantly maintained at a user-set pressure value ranging from 0 to 3 bar.
Structural features
The pure steam generator consists of two parallel columns: a double-shelled tube sanitary clean exchanger.
In addition to contaminating the column.
The equipment is all made of AISI 316L stainless steel, and the working surfaces of the cylinders and exchangers are subjected to standard procedures for pickling and purification.
A gasket of pharmaceutical grade PTFE is used.
All components are mounted on a sturdy carbon steel bracket for easy removal and assembly.
Mineral wool insulation, surface covered with AISI304 stainless steel satin polished protective layer.
S-type pure steam generator working principle
The working process of the S-type pure steam generator is as follows: the raw water enters the pipe of the separator through the feed pump (the two are connected), the liquid level is controlled by the liquid level sensor and the PLC, and the industrial steam enters the evaporation. In the shell process of the device, the raw material water in the management is heated to the evaporation temperature, and the raw material water becomes steam. The steam is separated from the raw water by gravity in the low speed and the height stroke of the separator. Re-evaporation, steam enters the various distribution systems and points of use.
The adjustment of the industrial steam allows the pressure of the pure steam to be set according to the procedures of the Shengchao process and can be stably maintained at the pressure value set by the user. During the evaporation of the raw materials, the supply of raw water is controlled by the liquid level, so that the liquid level of the raw water is always maintained at a normal level, and intermittent discharge can be set in the program for the concentrated water.
F-type pure evaporation generator works
The raw material water is heated by the industrial steam in the first effect preheater, and the second effect preheater is further heated by the industrial steam condensed water; then enters the top of the evaporator through the water dividing device, uniformly distributed into the evaporation column tube, in the evaporation column A film-like water flow is formed in the tube; these water streams are quickly evaporated due to the thinness, generating secondary steam; the raw water that has not been evaporated is discharged to the outside of the machine. The evaporated raw water, now secondary steam, continues to spiral up in the evaporator and is passed through the steam-water separation unit as pure steam from the steam outlet. The industrial steam is condensed into industrial steam condensate as a heating source of the preheater after the evaporator is absorbed by the raw water, and the raw water is preheated and discharged from the non-condensed water discharge outlet of the preheater. The trace pure steam is collected by the condensing sampler and exchanged with the cooling water to be cooled to become distilled water. After the on-line detection of the conductivity, it is judged whether the pure steam is qualified.
The secondary steam converted from raw water is clean steam, which undergoes three separations: after entering the evaporator at the beginning of the Zui, it flows down the column tube and simultaneously evaporates, which is * times separation; the evaporated raw water (secondary Evaporation) is folded back 180 degrees at the lower end of the evaporator. The impurities are separated into the lower part by gravity. This is the second separation. The evaporated raw material water, ie secondary evaporation, continues to spiral up in the evaporator. At the upper special separation device, a third separation is performed.
In the raw material water, there is a part of gas which cannot be condensed into water, which is called non-condensable gas. This part of non-condensable gas is provided with a continuous discharge device of non-condensable gas at the top of the evaporator according to the degree of automatic control.
Multi Span Plastic Film Greenhouse
Arch greenhouse is a kind of economical greenhouse, which is welcomed by the users with graceful curve form and low cost. It has beautiful appearance, fluent visual, reasonable structure and good performance for keep temperature. It is economical greenhouse because of its relatively low manufacturing cost. It can be applied in most areas of China. Double membrane greenhouse is used more in north of China, while single film greenhouse is used more in southern region. It can get maximum sunlight when visible light is within the scope of 0.4 to 0.7 microns and form a thick envelope, which can effectively prevent heat loss and prevent the invasion of cold air. Adopting a double membrane can greatly improve heat preservation performance of the greenhouse and save operating cost. The top cover material is polyethylene lifelong anti-fog and anti-dipping film po-covering. The outer of it has the function of UV protection and the inner has the function of preventing from the sets of dew. According to the needs of customers, the sides of the greenhouse can be covered with polyethylene lifelong anti-fog and anti-dripping po-covering or polycarbonate hollow plate.
