Abstract
The invention discloses an inlet fluid-infusion annular spraying device for an MVR (mechanical vapor recompression) compressor. The inlet fluid-infusion annular spraying device for the MVR compressor is mainly and structurally characterized by comprising two flanges with different sizes, which are overlapped and assembled in a concave-convex way; an annular flow channel is formed between the two flanges; the overall appearance structure size is consistent with a standard flange so as to facilitate the installation of a pipeline. According to the inlet fluid-infusion annular spraying device for the MVR compressor, the purpose of inlet fluid-infusion of the MVR compressor is mainly realized; spraying holes are uniformly distributed inward along the annular flow channel; the fluid mist sprayed from each spraying hole mutually interferes with each other in the direction which is perpendicular to a suction pipeline of the compressor, so that the fluid mist is more uniform; the infused liquid is atomized uniformly and stably and enters the compressor under the drive of a vapor flow. A fluid infusion amount is adjusted by mounting the devices, such as a flow adjustment metering pump or a flow adjustment valve, on the fluid-infusion pipeline, so that predetermined working conditions of the compressor is realized.
Description
Technical field
The present invention relates to function of mechanical steam recompression system (being called for short MVR), belong to evaporation industry energy-saving technology.
Background technique
MVR system is overheated for realizing the prevention of compression function output saturation steam, conventionally to splash in compressor steam suction port side the liquid of medium of the same race, the medium that enters compressor presents vapour-liquid two-phase simultaneously, simple spray means can be aggravated the risk of cavitation effect, the impact effect that can form to compressor drum high speed raindrop under compressor suction line air-flow drives as inhomogeneous in fluid infusion, there is the consequence of similar " dripping water wears through rock " in serious situation exactly.Compressor drum constantly stands such fatigue impact, and can greatly shorten working life.Apparatus of the present invention can not only obviously reduce the risk that occurs cavitation effect, also convenient by installing on connected replenishing line, Flow-rate adjustment is measured the automatic control of pump or two kinds of modes of the installation manual control of flow control valve regulate amount infused, to realizing the predetermined operating mode of compressor.
Summary of the invention
The present invention mainly solves MVR suction port of compressor fluid infusion problem, and adopting ring runner to be evenly arranged spray holes can realize and stablize even vaporific fluid infusion at compressor steam suction line, effectively reduces the risk that cavitation effect occurs, and improves compressor working life; Control flexibly the running state of compressor by change the means of amount infused at replenishing line device for installing and adjusting simultaneously.
This device main structure is made up of two concavo-convex overlap assemblies of the flange varying in size, the middle ring runner that forms, and monnolithic case physical dimension is consistent with standard flange, so that pipeline is installed.At make even face in Central Symmetry position flange radial direction perforate installation code threaded coupling of the adjacent two mounting hole place flange excircle side faces of flange, this hand-hole interface connects replenishing line.Fluid infusion hand-hole is communicated with ring runner at Flange Plane directional steering after entering flange certain depth, changes like this injection that forms an angle of the tangential shape of liquid flow direction and ring runner, just can make liquid rotate in ring runner.Be evenly arranged several spray holes along liquid flow direction at ring runner inner side surface circumference and Flange Plane direction, each hole emission direction unanimously all forms an angle with flange radial shape; Spray holes diameter gets little but difficult obstruction as far as possible and spray velocity must not be higher than 30 metre per second (m/s)s.Each spray holes ejection liquid mist interferes with each other and more even in compressor suction line vertical surface, and under the drive that sucks steam, institute's uniform and stable vaporificization of fluid infusion body enters compressor cavity.
Flow regulator is installed on replenishing line, can be the Flow-rate adjustment metering pump that automaticity is higher, can be also that hand flow regulating valve or other Flow valves regulate, and valve regulated requires institute's fluid infusion body to carry certain pressure.Flow regulator can regulate the number of amount infused at any time, thereby can control flexibly the work condition state of compressor, and this is one of MVR system control key element.
Accompanying drawing explanation
This contrive equipment entirety presents standard flange formula structure.Dotted line express liquid runner in Fig. 1, the mobile and injection direction of the fine rule express liquid with arrow; Fig. 2 represents the main structure of this device, and broken section has shown the structure situation of one of liquid injection port, runner and nozzle.
Embodiment
Institute's fluid infusion body first passes through flow regulator, and accurately means adopt metering pump to control amount infused by rotational speed regulation exactly, facilitate automatic operating; Flow control valve is fairly simple means.After Flow-rate adjustment, possesses the interior rotation of liquid spray injection device ring runner of certain pressure, liquid is at each spray holes ejection liquid mist of circumferencial direction under pressure, and in steam suction line vertical surface, interfere with each other more evenly, then institute's fluid infusion body is followed together uniform and stable vaporificization of vapor stream and is entered in compressor.
Claims (5)
1.MVR suction port of compressor fluid infusion ring-type spraying device main structure is made up of two concavo-convex overlap assemblies of the flange varying in size, and monnolithic case physical dimension is consistent with standard flange, is convenient to pipeline and installs and exchange.
2. the ring runner that two flanges form is one of major character of this device, and ring runner being connected with the angled direction of runner tangential direction, makes liquid rotate in ring runner with the fluid infusion hand-hole from flange outer radial direction like this.
3. be inwardly evenly arranged several spray holes along liquid flow direction at ring runner circumferential flange in-plane, each hole emission direction unanimously all forms an angle with flange radial shape, and each spray holes ejection liquid mist interferes with each other and more even in steam suction line vertical surface.
4. Flow-rate adjustment metering pump is installed on replenishing line, is changed amount infused and the running state of accurate automatic control compressor by adjusting rotary speed.
5. Flow-rate adjustment valve regulation amount infused also can be installed on replenishing line and change compressor operating operating mode.
