Operational features:

    Under the net from the slurry was diluted by white puddle and was pumped to the ZPC-type Cleaner is divided into paragraphs. The end of the segment Cleaner recommend the use of dilution water with low solids content of the water - for example, sealed from the suction pit or a white water tank filter water. This can greatly reduce the number of the end of the segment Cleaner. Cleaner good from the pulp through a number of nozzles into the degassing device device top form droplets, and the formation of a layer of slurry wall in the device film. Device near the body of the absolute pressure of the boiling slurry pressure. Due to the high vacuum and paste the collision, can effectively separate the air from the slurry is removed through the vacuum pump Nessler discharged from the tank. In addition to gas after the slurry by gravity flow to low-pulse pump, and through the net paper machine screen sent to the paper machine headbox. Sizing headbox slurry bypass pipe to return to the degassing device. In addition to air through the overflow device to maintain a stable level for the low-pulse pump provides a constant suction pressure head, allowing flow of slurry to stabilize the pressure inside.

 Structure Principle:

    ZCQ series of degassing is controlled by a multi-vessel into the slurry injection pipe, high-pressure nozzle rotation rate of arrival, overflow weir plate and degassing device and physical device composed of. Sizing the system installed in the machine ZCQ series of degassing device, from the Cleaner to the slurry, in order to pressure into the slurry into a multi-branch pipe, through a high rotation rate of the nozzle, a strong jet to the outgassing on the top , so that slurry fragmented into many small droplets, and form a layer along the cylindrical surface of outgassing device sports film; and outgassing of vacuum inside the slurry produced on the role of boiling, so that the slurry free gas and air bubbles in the low-pressure began to expand; and impact rupture, its combination of residual and the air has also been effectively separate spray, impact, boiling the three physical effects, so that **0% of the air in the slurry extrusion, fiber is also Flocculation to be ease. Meanwhile, the slurry concentration of volatile sub-classified as a small independent component monomer, and the degassing device body to stay a certain time, in a specially designed under the action of the weir plate, so that in addition to gas-slurry flow into a reverse flow inside, while the effectively control the frequency is higher than 0.*3HZ pulse and the concentration of the slurry flow volatility. 1, injection of slurry through the Cleaner Spinjet low drop-ejector nozzle, spray nozzle to maximize the effects of exposure to droplet size, improve air removal.

 2, the impact of jet crash into the slurry outgassing on the top, smash the pulp in the fiber bundle so that the fiber on the adhesion of air bubbles out. In addition to the inner surface of gas device that can prevent any scaling occurs.

 3, boiling degassing device through the self-adjusting vacuum system makes the absolute pressure within the slurry maintained at a temperature corresponding to the boiling point, thus ensuring that devices in addition to gas from the air can be cleared.

 Uses

 ZCQ series of pulp degassing device sizing system, a modern paper machine key equipment. Device Cleaner and low pulse between the net sieve, separation and extrusion slurry **0% air. Make slurry into the headbox, the pulp before the elimination of pressure, flow or concentration changes, while maintaining its stability is conducive to the formation of paper pages, the quality stability, productivity improvement.

 Features

 1, through the jet and falling film on the surface of the impact of fluid, vacuum and other physical effects, and residence time to achieve complete degassing slurry Internet.

 2, so that the slurry into the headbox concentration of stability, slurry flow and pressure stability; copy paper Zhang quantitative changes in small, poor quality will be greatly enhanced.

 3, preventing rot pulp production, prevent foaming, reduce the concentration of dirty material; to the Department of dehydration machine net improvement in the evenness of paper pages better, productivity is improved.
