Peculiarity:
As shown in the figure below, the continuity of the distribution of nitrogen purity in the bed of the adsorption tower from the bottom to the bottom and the top to the high is improved, and it is easy to quickly produce qualified nitrogen with pure purity.
Reduce the raw material air consumption, ensure the continuity of nitrogen purity distribution in the adsorption tower bed, and improve the nitrogen production efficiency of carbon molecular sieve, which changes the history that high-purity nitrogen (99.9995%N2) cannot be produced by pressure swing adsorption technology.
Reduce the load of the compressed air purification unit, improve the pretreatment effect of raw material compressed air, and ensure the performance index of carbon molecular sieve.
The higher the purity of nitrogen, the more significant the energy saving effect.
Peculiarity:
The actuator made of the piston and the valve core is integrated, and the rigidity and stability are superior.
In the process of opening and closing, the wear resistance and sealing of the sealing surface are good.
The opening and closing stroke is small, the circulation area is large, and the pressure loss is small.
Quickly complete the opening and closing action within (0.3~0.5) seconds.
The fluctuation of the pressure difference between the front and back of the valve does not affect the opening and closing speed of the valve.
The valve action indication is intuitive, and the feedback part is indicated.
Compact structure and easy installation.
It is convenient for long-distance pneumatic control.
The wearing parts (seals) have a long service life of up to 2 million cycles.
The body is made of stainless steel and has a long service life of 20 years.
Peculiarity:
According to the specifications of the adsorption tower, cylinder pressing devices of different specifications are configured to ensure that the molecular sieve is always in a compressed state.
Directly display the sinking position of the carbon molecular sieve
It has the function of sinking alarm and limit shutdown.
The drive gas is taken directly from the adsorption tower.
The hydraulic check device is used to prevent the cylinder piston from moving. (QG-10-500)
The compression force is constant, and does not change with the displacement of the molecular sieve, and does not change with the pressure fluctuation of the adsorption tower.
The unique structure design of the adsorption tower effectively changes the speed and direction of the air flow in the adsorption tower, reduces the generation of dead space in the adsorption tower, and further improves the utilization rate of molecular sieves.
At the same time, it avoids the impact of high-speed air flow on the molecular sieve, reduces the pulverization of the molecular sieve, is conducive to prolonging the service life of the molecular sieve, improves the adsorption performance of the molecular sieve, and reduces energy consumption.
When the gas production does not reach 100%, the molecular sieve does not reach the adsorption saturation state, and can be used for adsorption for a period of time, thereby reducing the number of exhaust gas emissions per unit time and reducing the air consumption of the equipment.
Purity anti- vibration technology
According to the characteristics of the pressure swing adsorption gas production equipment, under the condition that the gas supply volume remains unchanged, the gas production equipment decreases with the increase of raw gas temperature or the attenuation of adsorbent performance, and the purity of product gas decreases. With the increase of gas consumption, the purity of product gas decreases, which is easy to cause unqualified product gas purity to cause gas production equipment to empty and run, and even swing the machine, resulting in energy waste, gas shutdown and huge economic losses to users.
The purity anti-vibration technology can greatly reduce energy consumption, and increase stability.
