Steam jet heat pump
Steam jet heat pump can be used in the following aspects:
Low pressure steam booster reuse some factories use several different pressure steam at the same time, and the heat source and can't meet, then can use steam jet heat pump will be part of the low pressure steam pressure, in order to meet the needs of industrial production.
Equipment exhaust steam recycling some steam equipment, due to its low exhaust pressure, cannot be reused. Steam jet heat pump can be used to add steam to the steam pipe network, which can be reused.
The recovery system of flash vapors is shown in FIG. 2. The flash vapors generated by condensate entering the flash tank are sucked away by the heat pump and pressed to supply production or life.
Characteristics of steam jet heat pump:
1. Easy to operate and easy to maintain, which can guarantee the stability of supply and pressure.
2. The energy saving benefit is remarkable. In the recycling enterprise, the low pressure steam and flash steam can be used to recover the steam price, and the annual steam value is worth hundreds of thousands to more than one million.
3. Automatic control system can ensure that the vapor pressure is unchanged within the range of 30%-100%, and the effect of the limited fluctuation of thermal users on the equipment efficiency is solved.
Main performance indexes and parameters of steam jet heat pump:
The performance index of jet heat pump is the ejection coefficient. The ejection coefficient is equal to the inlet steam flow/drive steam flow; The numerical value of the ejection coefficient is related to the main parameters of the steam jet heat pump.
Main parameter expansion ratio =PP/PH; Compression ratio = PC/PH;
PP - drive steam pressure PH - ejection steam pressure PC - mixed steam pressure.
The structure size of the heat pump shall be designed and manufactured separately according to the steam parameters of the user.
