Description
Technical field
The present invention relates to waste removal equipment field, more particularly, relate to a kind of RVP railway vacuum evacuation system.
Background technology
Common vacuum system vacuum tank adopts the on-the-spot glass tube of manual observation to control the liquid level of vacuum tank, owing to containing a lot of hard rubbish and foreign material in the sewage of train, pipeline very easily blocks, dredge pump can be caused in running not start, vacuum pump is vacuumizing always, easily the sewage of vacuum tank is filled, thus sewage is drawn into steam-water separator and vacuum pump through vacuum pipe, causes the damage of vacuum pump.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of railway vacuum evacuation system.
Railway vacuum evacuation system of the present invention, comprises vacuum pump, vacuum tank, steam-water separator and dredge pump; Passenger vehicle dirt box sucks vacuum line by sewage and connects vacuum tank, and vacuum tank connects steam-water separator and vacuum pump successively by vacuum line, and vacuum tank is by pollutant discharge vacuum pipeline connecting pipe crushing engine and dredge pump successively; In vacuum tank, pressure vacuum gauge, vacuum pressure sensor, radar level gauge are installed; Described vacuum pump, dredge pump, pressure vacuum gauge, vacuum pressure sensor, radar level gauge are connected with on-the-spot PLC control system respectively.
Described vacuum pump connects deodorizing spray column successively by pipeline liquid injecting device.
Compared with prior art, the invention has the beneficial effects as follows:
The mode that vacuum system of the present invention adopts magnetic flap level gauge to combine with radar level gauge carrys out the startup of control of sewage disposal pump, magnetic flap level gauge not belt controling signal, only for the display at scene, for the liquid level in naked eyes viewing vacuum tank, radar level gauge belongs to General Radar content gauge, it is based on the measuring instrument of time stroke principle, and radar wave runs with the light velocity, and running time can be converted into thing position signal by electronic unit.Probe sends high-frequency impulse and propagates along hawser, reflects and is received by the receiver in instrument, and distance signal is converted into thing position signal when pulse runs into material surface.
Vacuum system of the present invention installs pipeline delumper additional before dredge pump, ensure that the normal operation of dredge pump and has greatly often prolonged application life.
The by-pass valve control of vacuum evacuation system of the present invention all adopts stainless steel knife gate valve, and blow-off line not easily blocks, system longer service life.
The vacuum degree control of vacuum system of the present invention adopts pressure vacuum gauge and vacuum pressure sensor double control, and the stable of system more can ensure.
Railway vacuum evacuation system adopts online assignment form, and system vacuum remains between-10kPa ~-50kPa, can realize the continuous running of suction face to pressure face.
The complete airtight free from extraneous odour of each several part vacuum line of the present invention, without blocking, without gas leakage, leakage of oil, leak and leak the phenomenon of dirt, meeting the requirement of environmental protection, energy-saving equipment advanced technology.
Railway vacuum evacuation system can meet 8 or 16 marshalling various motor train unit trains of CRH and the suction of general fast passenger vehicle dirt box, rinse and the needs of discharge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, railway vacuum evacuation system of the present invention, comprises vacuum pump 5, vacuum tank 1, steam-water separator 4 and dredge pump 3; Passenger vehicle dirt box sucks vacuum line by sewage and connects vacuum tank (the implementation case adopts 2 vacuum tanks), vacuum tank connects steam-water separator and vacuum pump (the implementation case adopts three groups of steam-water separators and vacuum pump) successively by vacuum line, and vacuum tank is by pollutant discharge vacuum pipeline connecting pipe crushing engine 2 and dredge pump 3 successively; In vacuum tank, pressure vacuum gauge, vacuum pressure sensor, radar level gauge are installed; Described vacuum pump, dredge pump, pressure vacuum gauge, vacuum pressure sensor, radar level gauge are connected with on-the-spot PLC control system respectively.Described vacuum pump connects deodorizing spray column 7 and 8 successively by pipeline liquid injecting device.
By vacuum pump, vacuum tank being evacuated to setting vacuum, by starting to aspirate, carry dirt in vacuum tank after extraneous and the intrasystem pressure differential of soil pick-up pipeline, after reaching certain setting liquid level, automatically carrying out blowdown.
Vacuum pump suction makes system produce vacuum and forms negative pressure, and dirt suction is delivered in vacuum tank temporary, and when sewage in vacuum tank reaches design liquid level, dredge pump starts automatically by effluent discharge in tank.
Vacuum pump and dredge pump can run automatically according to the vacuum pressure scope of setting and two position.
Adopt on-the-spot PLC control system to control, monitored by pressure vacuum gauge and vacuum pressure sensor automatic pressure and control the running of vacuum pump, the running according to the automatic control of sewage disposal pump of the signal of radar level gauge; Operation system setting malfunction coefficient and warning function, can show working vacuum degree and working condition.System automatic control equipment runs and produces vacuum and discharge dirt, without the need to human attendance.
Vacuum pipe adopts high-quality tubing, features such as having inner wall smooth, resistance is little, effective discharge is large, pipe joint is few, method of attachment is many, be easy for installation.
The dredge pump that this practicality newly adopts has following characteristics:
1, unique mill twin shaft design, separate cutting blade and pad is adopted to be arranged on two parallel axis of rotation, alternately stacked, realize spiral cutting, reach good cutting effect, the alloy steel processing and manufacturing of special substance selected by cutting blade and pad, surface uniform, intensity is high, ensures the thorough pulverizing of particle object in crushing process of unlike material.
2, the unique design of blade, can pulverize rigid and flexible impurity, coupling rotational under the drive of motor reducer, produces powerful extruding force and scissors power, thus hard solid thing in pipeline and flexible impurity is thoroughly pulverized.Low-speed handing moment of torsion is large, effective.
3, according to different inflows, pipes crasher has less head loss, increases circulation effect, makes current more smooth;
4, the combination sealing arrangement of mechanical seal box outside framework oil seal is adopted, without the need to rinsing sealing, adjusting.Very convenient in use technology process;
5, when generation solid blocks or when blocking, supporting control cabinet can send signal to mill, make blade auto-reverse, obstruction is exited re-starting pulverizing again, realize the intelligentized control method of whole process, meet unattended requirement.
The radar level gauge tool that this practicality adopts has the following advantages:
1, radar level gauge can measure liquid, solid dielectric such as: crude oil, slurry, raw coal, fine coal, volatile liquid etc.;
2, can measure the medium can measuring All Media constant >1.8 in a vacuum, measurement category can reach 35m;
3, power supply and output signal are by two core cable (loop circuit), adopt 4 ... 20mA exports or numeric type signal exports;
4, the material firm and durable that non-contact measurement employing easy for installation is extremely stable, accurately reliable resolution ratio can reach 1mm;
5, do not affect by operating modes such as noise, steam, dust, vacuum.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
