Description
Technical field
The utility model relates to a kind of Venturi tube orifice plate compound Hydrodynamic cavitation device, belongs to reaction unit design ap-plication field.
Background technology
Hydrodynamic cavitation refers in process fluid flow, owing to the change of speed causes the formation in hole (cavity) that the pressure field of fluid changes and cause, the process of growth and collapse. Owing to Hydrodynamic cavitation reaction process is strong, so being often used to the process intensification of various reaction. Hydrodynamic cavitation reaction unit has the advantages such as volume is little, structure is simple, energy consumption is low, strong reaction, but conventional Hydrodynamic cavitation device, as little in the reaction area such as Venturi tube, orifice plate, cavitation effect is poor, it is difficult to meet actual service requirements.
For this reason, design Venturi tube orifice plate compound Hydrodynamic cavitation device, conventional Venturi tube and orifice fitting are combined as a whole by this device, and the function of Venturi tube and orifice plate is combined by this device, solve the shortcoming that single device response intensity is low, it is to increase Cavitation efficiency.
Summary of the invention
The purpose of this utility model is to provide Venturi tube orifice plate compound Hydrodynamic cavitation device.
The utility model solves the technical scheme that its technical problem adopts: Venturi tube orifice plate compound Hydrodynamic cavitation device, comprise: inlet pipe, flange mounting hole, trunnion, bolt, nut, outlet pipe, orifice plate, seal washer, it is characterized in that: Venturi tube orifice plate compound Hydrodynamic cavitation device is primarily of Venturi tube and the orifice plate composition being arranged on its trunnion place, wherein Venturi tube is divided into inlet pipe and outlet pipe two portions, two portions are connected by bolt and nut, orifice plate is arranged on two pipe junctions, the mouth of pipe at inlet pipe and outlet pipe arranges flange mounting hole, it is connected with other pipeline by flange mounting hole, in the side of orifice plate, seal washer is set, liquid flows into from the inlet pipe of Venturi tube, contraction section at inlet pipe reduces due to sectional area, flow rate of liquid is accelerated, liquid pressure reduces, when arriving trunnion place, under throat's pressure is reduced to liquid saturated vapor pressure, water vapour and the bubble being dissolved in water overflow, after liquid movement to trunnion end, due to liquid pressure fluctuation, part bubble is broken bursts, there is first cavatition, when liquid moves forward, during by the orifice plate of trunnion end, gas overflows further, after orifice plate, liquid raises at expansion pipeline section pressure, bubble is broken bursts, produce strong cavatition.
The beneficial effects of the utility model are: on the one hand, the function of Venturi tube and orifice plate is combined, solve the shortcoming that single device response intensity is low, improve Cavitation efficiency, on the other hand, Venturi tube is divided into inlet pipe and outlet pipe two portions, reduces difficulty of processing, and installs and change convenient.

The inlet pipe 1 of Venturi tube orifice plate compound Hydrodynamic cavitation device is the influx of liquid, and flange mounting hole 2 can be used for being connected the devices such as this device and other pipeline, and orifice plate 3 is a kind of Hydrodynamic cavitation device. Seal washer 4 has sealing effect. Bolt 5 and nut 8 are used for fixing inlet pipe 1 and the outlet pipe 6 of Venturi tube. Outlet pipe 6 is the spout of liquid. Trunnion 7 is used for fixing orifice plate 3, is the generation place of Hydrodynamic cavitation reaction simultaneously.
Venturi tube-orifice plate compound Hydrodynamic cavitation dress forms primarily of Venturi tube and the orifice plate 3 being arranged on its trunnion 7 place, and wherein Venturi tube is divided into inlet pipe 1 and outlet pipe 6 two portions, and two portions are connected by bolt 5 and nut 8, and orifice plate 3 is arranged on two pipe junctions. Flange mounting hole 2 is also had at the mouth of pipe of inlet pipe 1 and outlet pipe 6. Also it is lined with seal washer 4 in the side of orifice plate 3, it is used for enhanced leaktightness effect.
This Hydrodynamic cavitation device is in use, liquid flows into from the inlet pipe 1 of Venturi tube, and the contraction section at inlet pipe 1 reduces due to sectional area, and flow rate of liquid is accelerated, liquid pressure reduces, when arriving trunnion 7 place, under throat's pressure is reduced to liquid saturated vapor pressure, water vapour and the bubble being dissolved in water overflow, after liquid movement to trunnion 7 end, due to liquid pressure fluctuation, part bubble is broken bursts, and first cavatition occurs. When liquid moves forward, during by the orifice plate 3 of trunnion 7 end, gas overflows further, and after orifice plate 3, liquid raises at expansion pipeline section pressure, and bubble is broken bursts, and produces strong cavatition.
The utility model provides a kind of Venturi tube orifice plate compound Hydrodynamic cavitation device, reasonable in design, structure is simple, it is easy to operate to have, install and change the advantages such as convenient, practical, overcome that conventional Hydrodynamic cavitation device reaction area is little, cavitation effect is poor, it is difficult to meet the problem of actual service requirements, this device market potential is big, it is possible to commercially promote.
