Utilize system.
Background technology
Steam is as a kind of widely used energy, frequently as thermal source or power source, steam in industry and civil engineering
Discharge heat energy or acting after, pressure and temperature is relatively low, or condensed water in high temperature flash distillation after caused byproduct steam, quality compared with
It is low, it often can not further utilize, can only directly discharge the waste in an atmosphere, causing heat energy and water resource, and cause heat
Pollution, influences atmospheric environment and working environment.
The vulcanizing equipment of rubber industry, as vulcanizing tank, vulcanizer need steam to vulcanize as thermal source to rubber product,
, it is necessary to first bleed off the steam inside vulcanizing equipment before the operation that discharges, subsequent operation could be carried out.This some vapor needs
Racked up in setting time, and also reach normal pressure, and be intermittent operation, pressure is relatively low, and amount is little, utilizes existing technique
It is difficult to recycle.
There are several process routes to this both at home and abroad at present：One is being passed through an exhaust steam tank, tank top is directly discharged into greatly

Steam pipe is in line, and not only heat energy can not utilize this some vapor, but also can cause plant area's thermal pollution, adverse condition, high humility
Dust polymerize in drop and air, is also easy to produce aerosol, exacerbates the formation of haze weather；
The second is be passed directly into gas utilization unit, but because the low pressure exhaust steam pressure is relatively low, density it is small, it is necessary to pipeline it is thicker,
It can not more importantly build the pressure, the normal operation for the process equipment that can influence front end that builds the pressure, operational effect is poor；
The third is using steam jet ejector（Also referred to as jet pump）, by the use of high steam as power, injection low parameter steam, add
Utilized after pressure mixing as live steam, but the program has significant limitation, because the steam of vulcanization plant discharge is interval
Property, cut in and out, can not realize that continuous compression utilizes by steam jet ejector；
The fourth is using vacuum pumping low parameter steam, utilized as thermal source, but vacuum pump system initial cost is larger, running cost
With higher, the investment repayment phase is longer, and caused condensate can not recycle, and is directly discharged into sewerage or circulating water
System, high-quality low use, causes the waste of water resource.
In summary, there is the drawbacks such as not strong, the inefficient, system complex of operability in existing process route.How to carry
For a kind of simple system, easily operated low pressure exhaust steam recycling system, realize high efficiente callback to low pressure exhaust steam and
Utilize, be the technical issues that need to address.
