Description
Technical field
The utility model is related to MVR evaporation techniques field, the compressor anti-surge dress of particularly a kind of MVR vaporising devices
Put.
Background technology
In recent years, as domestic manufacturing industry Efforts To Develop energy conservation is transformed, MVR vaporising devices are new as one kind
Energy saving evaporator, with its excellent energy conservation and consumption reduction effects, just progressively substitute traditional triple-effect evaporation plant.MVR evaporation dresses
Put and system is maintained into negative pressure state using vavuum pump, so as to reduce material boiling point, this is first key element of its energy-conservation；Its section
Second key element of energy, is the steam temperature raising produced to the evaporation in gas-liquid separator using compressor, is then recycled.
The introducing of MVR vaporising devices, device power consumption increases, and the steam consumption of device is substantially reduced, its comprehensive energy consumption entire lowering half.
The compressor of MVR devices is centrifugal compressor, and rotating speed, generally in more than 3000r/min, is the key of MVR devices
Equipment.Centrifugal compressor will evaporate the both vapor compression of generation in MVR devices, so that 10 DEG C or so of vapor (steam) temperature is lifted, finally
Reach the purpose for recycling.Centrifugal compressor is due to the unbalanced easy initiation surge of flow Q and pressure head H, MVR vapour pressures
Contracting machine import and export pipe diameter is generally larger, and rotating speed is very fast, and it triggers the probability of surge to greatly increase again.Surge can not only be destroyed
The flowing law of machine interior media, produces mechanical noise, while can also cause the judder of workpiece, accelerates bearing
With the damage of sealing；When surge causes pipeline, machine and its basic resonance, more serious consequence can be also caused.This technology
Purpose be exactly that Compressor Pipes are transformed, so as to be prevented effectively from the surge of compressor.
The analysis found that, have the reason for compressor may trigger surge in MVR devices it is following some：1st, compressor inlet
It is evaporator, the unstable of evaporator evaporation amount certainly will cause the unstable of compressor inlet tolerance, so as to cause compressor to enter
Mouth flowed fluctuation, when compressor inlet gas flow is less than critical point flow, will cause surge.2nd, the evaporation capacity of evaporator
The unstable obvious fluctuation that can also cause compressor inlet air pressure, it is obvious so as to cause compressor inlet outlet pressure differential to change, enter one
Step influence compressor normal working point, so as to increase the possibility for inducing surge.3rd, compressor is in startup procedure, evaporator gas
Amount cannot keep up with compressor normal work institute air demand, so as to trigger surge.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of compressor anti-surge installation of MVR vaporising devices,
The surge of compressor is avoided using reflux line, the steady of compressor inlet and outlet pressure and flow is realized using instrument and meter for automation
It is fixed, the normal working point of compressor is ensured, so as to further ensure the normal operation of system.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of compression of MVR vaporising devices
Machine anti-surge installation, including gas-liquid separator and compressor, are connected with inlet pipeline and outlet conduit on the compressor, compression
Machine is connected by by inlet pipeline with the top of gas-liquid separator；It is also associated with back between the inlet pipeline and outlet conduit
Flow tube road, the reflux line is provided with magnetic valve.
Preferably, it is equipped with pressure converter on the outlet conduit and at the top of gas-liquid separator.
Preferably, the pressure converter and magnetic valve are connected with controller.
Preferably, the controller is Siemens's ET200MPLC controllers, the pressure converter（7）It is 3151 pressure
Converter.
Preferably, the controller is also connected by RS485 communication interfaces with host computer.
The utility model provides a kind of compressor anti-surge installation of MVR vaporising devices, effectively reduces centrifugal compressor
There is the possibility of surge in machine, not only avoid the abrasion of machine seal member and bearing in MVR devices, ensure machine
Continuous operating time, and avoid the more serious consequences such as pipeline, machine and its basic resonance that surge causes.
