_ rotary-vane vacuum pump for steam condensation water industry

by:J&T     2020-07-08

how to effectively recycle steam condensate is the current volume need to solve the problems in the process of production. Some customers has already consulted before this aspect of the problem. At that time, the technical personnel is given using rotary vane vacuum water pump in steam condensation water solution, because it USES a technical background: in the process of DCP production, oxidation, need a certain amount of low pressure steam. Distillation section, as well as finished products processing, as well as the whole production process of some auxiliary section of the need for continuous hot water heating, some critical reactor need to directly participate in hot water.

with the continuous development of vacuum technology, the application of the vacuum pump is more and more widely, with our single-stage rotary vane vacuum pumps with double rotary vane vacuum pump performance, our company can offer specific solutions for you. The actual situation. The solution to meet the application requirements.

steam as a kind of clean and safe energy carrier, is widely used in electricity, petroleum, chemical industry, printing and dyeing, papermaking, textiles, brewing, rubber, ceramics and other industrial fields. Steam in all equipment after the release of the latent heat of evaporation, at the same temperature and same pressure into the saturation of condensate. Due to the vapor pressure is greater than atmospheric pressure, the quantity of heat of condensation water can reach 20% of the total quantity of heat of steam. 30%, the higher the pressure and temperature, the quantity of heat of condensation water, the more the greater the proportion of total quantity of heat of steam. As you can see, the quantity of heat of condensation water recycle and effectively, has a great potential for energy saving.

steam condensation water recycling method need to use appropriate methods according to the local situation, both the system design is simple, and fundamentally eliminate the problems in the operation maintenance, make steam condensation water recycling work smoothly. And out the other. Import rotary-vane vacuum pump are optimized in the whole production process, the steam condensed water collecting device is arranged in the production workshop, collection and recycling paragraphs steam condensation water, achieve energy conservation and emissions reduction. And can discharge of high temperature condensed water, make the most of the quantity of heat of condensation water, save water, save fuel. It to the factory to improve the economic benefits of the energy consumption and has important effect.

this is rotary-vane vacuum pump are how to recycle of steam condensed water.

during the compression stage in the rotary-vane vacuum pump are all or part of the condensing steam must also change in the process of distillation and drying. In this case, helps to remove pump discharge without condensation of steam. However, compatibility is not always enough to prevent condensation of steam. Mix condensate and oil will cause the increase of extreme pressure and the reducing of the working fluid lubrication ability. These factors will cause the corrosion of the pump. Before the steam discharge, rotary vane vacuum water pump must warm up at least half an hour.

high temperature working fluid to reduce condensation, and other ways to reduce condensation include only get low discharge pressure and discharge condensate, respectively. Therefore, we should use condensate separator in inlet side and outlet side. You must use the oil mist filter and vertical exhaust pipe to prevent the back pressure at the exit. If there are extraction system, the outlet should be connected to it.

dust, particles and chemicals: filters and separator can be under the condition of certain restrictions to protect rotary-vane vacuum pump from wear and corrosion. Equipped with polyester fiber ( SAS) Or epoxy glass fiber ( DFT) Filter separator can filter sticky dust. Activated carbon filter ( FAK) Combined with inorganic steam, the filler replaceable filters.

into hydrocarbons ( Oil vapor) Can be heated in the catalytic trap ( 市区) In catalytic incineration, and absorb zeolite trap ( ZFO or ST) All kinds of steam, the steam can be renewable when saturated by baking. Condensed water can be collected in the condensate separator ( KAS or CT) And manually in the discharge.
