Description
Technical field
The present invention relates to the system that a kind of high velocity jet effect by water obtains vacuum and condensing steam, particularly relate to a kind of intelligent water jet vacuum.
Background technique
Water jet vacuum is widely used in the industrial fields such as metallurgy, chemical industry, light industry, medicine, food.It is made up of circulating water pump, water injection vacuum pump, pressure instrumentation, circulation water channel, pipeline and process operation unit etc.Its working principle is: the work cycle WATER AS FLOW MEDIUM being provided system by circulating water pump, and the high-speed jet water produced by nozzle in water injection vacuum pump forms absorption negative pressuren zone, produces vacuum and the adsorption condensing effect to steam.Traditional water jet vacuum is the reliability of guarantee work, and is the situation of change adapting to pressure (degree of vacuum) in industrial production, usually needs to select the quantity of circulating water larger with employing compared with the water jet pump of large gauge.What namely adopt is a kind of rigid design of larger redundancy, and in normal working or when requiring compared with rough vacuum, system is still according to the Power operation of consumption peaks.Need the degree of vacuum be suitable in process of production, the redundancy negative pressure that water jet vacuum produces normally is discharged by the atmospheric valve be arranged on equipment or pipeline, creates extra energy ezpenditure.
Summary of the invention
The object of the present invention is to provide a kind of intelligent water jet vacuum, to overcome traditional water jet vacuum to bring energy dissipation defect according to larger redundancy rigid design method.
A kind of intelligent water jet vacuum, comprise circulation water channel, pipeline, it is characterized in that: the adjustable water ejector vacuum pump also comprising adjustable water flow velocity and flow, the frequency conversion water-circulating pump of regulating flow quantity, pressure transmitter, process operation unit, adjustable water ejector vacuum pump comprises pump case, cam mechanism, nozzle slide block, nozzle body, adjustable nozzle, nozzle slide block is driven to move by cam mechanism, make it to change with the nozzle cross-section size that formed on nozzle body, reach the object regulating jet size, according to practical operation needs, automatically can adjust the flow of quantity of circulating water and water jet pump nozzle water in water jet vacuum in good time, flow velocity, the degree of vacuum that water jet vacuum is produced and actual production adapt, avoid the waste of the energy.
The innovative point of this invention is: 1), adopt the frequency conversion water-circulating pump of regulating flow quantity to replace the non-adjustable water-circulating pump of traditional flow; 2), the adjustable water ejector vacuum pump of regulating flow quantity and flow velocity is adopted to substitute uncontrollable traditional water jet pump; 3), according to the analogue signal of pressure (testing degree of vacuum) transmitter, regulate the flow of circulating water pump and the flow of water jet pump nozzle and flow velocity in proportion simultaneously; 4), new software control pattern is realized by iterative computation, the flow of circulating water pump flow and water jet pump nozzle, flow velocity is made to obtain Optimum Matching, under the degree of vacuum provided requiring water jet vacuum and cooling steam amount condition, the power consumpiton realizing circulating water pump is minimum; 5), cancel on operating unit vacuum equipment or pipeline for regulating the logical air modulating valve of degree of vacuum.
The invention has the advantages that adopt can the method for timely adjustment quantity of circulating water and water injection vacuum pump nozzle flow velocity and flow, change traditional water jet vacuum not by changing quantity of circulating water, changing water jet pump nozzle flow velocity and flow, there is portion of energy waste problem in normal operation, is the energy-conservation water jet vacuum of a kind of novelty.According to estimation, this system can than traditional energy saving of system more than 25%, with evaporation capacity 3.0m
3the vacuum evaporator system of/h is example, and the electricity charge are in 0.6 yuan/degree, and conservative estimation at least can save the electricity charge 50,000 yuan every year.
This Method and Technology also has general meaning, can be applied on similar device and equipment.

Embodiment
Embodiments of the present invention are described in detail below in conjunction with accompanying drawing:
A kind of intelligent water jet vacuum, comprise circulation water channel 5, pipeline 4, it is characterized in that: also comprise the adjustable water ejector vacuum pump 2 of adjustable water flow velocity and flow, the frequency conversion water-circulating pump 1 of regulating flow quantity, pressure transmitter 3, process operation unit 6.Adjustable water ejector vacuum pump 2 comprises pump case 7, cam mechanism 8, nozzle slide block 9, nozzle body 10, adjustable nozzle 11, nozzle slide block 9 is driven to move by cam mechanism 8, make it to change with adjustable nozzle 11 cross-section size that formed on nozzle body 10, reach the object regulating jet size.According to practical operation needs, automatically can adjust flow, the flow velocity of quantity of circulating water and water jet pump nozzle water in water jet vacuum, the degree of vacuum that water jet vacuum is produced and actual production adapt, and avoid the waste of the energy in good time.
The technological process of intelligent water jet vacuum of the present invention is consistent with traditional water jet vacuum, but completely different on the equipment adopted and its working mechanism and control.First in equipment: the adjustable water ejector vacuum pump 2 adopting adjustable water flow velocity and flow; Adopt the frequency conversion water-circulating pump 1 of regulating flow quantity; Pressure transmitter 3 characterization processes operating unit 6 degree of vacuum is adopted to depart from the situation of setting value, to frequency conversion water-circulating pump 1 and adjustable water ejector vacuum pump 2 outputting analog signal.Concrete controlling method is: the control mode of employing is: when after the degree of vacuum receiving process operation unit 6 and pressure transmitter 3 analogue signal, frequency conversion water-circulating pump 1 and adjustable water ejector vacuum pump 2 are carried out presetting simultaneously, again according to the analogue signal variation tendency that pressure transmitter 3 feeds back, carry out adjusting again of frequency conversion water-circulating pump 1 and adjustable water ejector vacuum pump 2.The method of adjustment is whenever frequency conversion water-circulating pump 1 adjusts once, and adjustable water ejector vacuum pump 2 adjusts in a wider scope, seeks the degree of vacuum maximum value in given water yield situation.Repeatedly perform such iteration searching process, in the hope of reaching a minimum circulating water pump power.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; make some equivalent alternative or obvious modification without departing from the inventive concept of the premise; and performance or purposes identical, then should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
