Application of liquid ring vacuum pump in sugar industry
The reliable technology of liquid ring vacuum pump is proved by practice.
Liquid ring vacuum pump not only provide the products to you alone, our professional engineers will spend a lot of time, for your specific process, a comprehensive analysis to determine your needs, and then design the most suitable liquid ring vacuum pump/compressor system meet your ability to handle the most basic and vacuum or compression stress and the special performance requirements of your device, make our engineers to provide you with cost-effective optimal solution.
Liquid ring vacuum pump is used in sugar industry.
From plants to juice.
Sugar cane; After harvesting and transportation to the sugar refinery, the sugar cane is washed, divided and then chopped up by the hob. The sugarcane fragments are mixed with water many times and squeezed between the rolls. The juice is collected, and the solids with fiber (often called bagasse) are used as fuel or for making paper. The vacuum pump is used in all these processes.
Sugar beet; After harvesting and transport to the factory, beet was cleaning, mechanical cut into thin strip (usually called cossettes) and then through a diffuser them in the sugar content of soluble in water, the processed sugar beet wire or sugar beet is squeezed into 75% of the temperature, the energy for the recovery of the extra sugar and reduce drying. The beet pulp is then dried and sold as animal feed.
Rotary vacuum filter.
The available sugar is extracted from the mud at the bottom of the clarifier (filter) by a drum filter. Like many other industries, the NASH liquid ring vacuum pump is the preferred vacuum for these filters in the sugar industry. In operation, the slurry of the entrainment or even the soft solids will not damage the liquid ring vacuum pump.
Using NASH liquid ring vacuum pump can meet the requirements of vacuum degree, through the rotary drum vacuum filter in the washing period of need of vacuum pump is about 18 "HGV (equivalent to 405 mbar abs) in the pick up department takes about 10" HGV (equivalent to 675 mbar abs). Considering the pipeline pressure drop, which usually means in the entrance of the pump vacuum pump in the 21 "HGV 303 mbar (abs) when a vacuum pump is applied to two parts at the same time, in the pick up period of low vacuum degree can be regulated through vacuum regulator.
The condensation gas is extracted from the condenser.
Steam, air and other incompressible gases can be extracted from evaporators and vacuum tanks. The modern way is to use a single-stage vacuum tank to extract from the condenser.
In this wet vacuum system, a NASH vacuum pump ACTS as a secondary condenser. Liquid closely contact and air compression, condensation out most of the no removal of water vapor in the counterflow condenser, the importance of this role is water vapor into liquid will reduce the volume of liquid ring vacuum pump to deal with, it is to reduce the effect of the type of pump, compared with the dry air flow, significantly improve the ability of handling the NASH vacuum pump.
The increase in specific capabilities depends on the temperature difference between the liquid and the imported air, the vapor mixture.
Simple and reliable liquid ring vacuum pump, a sugar refinery in the production cycle of the middle closed production workshop due to high costs, they are looking for a simple reliable equipment, they chose our vacuum pumps and compressors.
The liquid ring vacuum pump/compressor feature ensures that you get a more uniform sugar crystallization.
Liquid ring vacuum pump structure material.
On the specification of material, need special attention when mixed with the water will produce carbonic acid, corrosive sulfur will be generated from the sulfur fuel, more than cause trouble, the effect is more to the usual material corrosion formation, unless to take appropriate preventive measures.
If the gas contains hard particles, they will cause wear and tear on the equipment. A successful measure is to install a wet scrubber upstream of the compressor.
If carbon steel compressors are used, the equipment needs to be protected by controlling the PH value of the sealant. It is recommended to add pure alkali in water and install PH detector. These precautions will extend the service life of carbon steel compressor, from one or two production cycle was extended to more than four production cycle, do not contain high sulphur in limekiln gas and fuel, has used for years to run reports.
For carbon dioxide compressors, stainless steel is a more durable material, and if you want a longer compressor life and a fail-safe system, consider stainless steel.
