Flue gas is made only to flow into organic Rankine bottoming cycle main system, it is ensured that exhaust gas volumn is sufficient.Disconnection divided current system step: first PLC3
Control triple valve III to open, make working medium be bypassed to condenser II, simultaneously close off decompressor II and generator II, treat system
After middle Temperature of Working declines, PLC6 control stop valve and pump cuts out, then divided current system will be closed, and treat heat
After source heat abundance, to wait to reopen.
Exhaust gas volumn in entrance system is shunted as subsystem by the present embodiment by arranging divided current system, so that logical
Cross the exhaust gas volumn of main system organic Rankine system, heat remains stable, makes system be in more stable running status all the time,
Avoid various parts to be chronically at overheated and high loaded process state affect its life-span and increase the problem of cost, pass through meanwhile
Whole waste heat recovery process is controlled by control system, makes the control to system more efficient, accurate, intelligent, it addition, the most logical
Cross overtemperature prote system to instantaneous high-temperature and the control of continuous high temperature, make system run more steady.
As the improvement of the present embodiment, include gas or liquid or flowable solid by the heat source medium in exhaust gases passes entrance system
Body, such as the middle low temperature waste gas produced in industrial process or waste water, and geothermal energy or other low-grade solid energy etc..
As the improvement of the present embodiment, the cycle fluid of system is that non-azeotrope mixes organic working medium, and its thermodynamic property is stable, profit
In the stability and the security that improve system.
