Description
Technical field
The present invention relates to a kind of Venturi nozzle, be applied to the dirt of buying (or sell) on credit of harmful mist, belong to frame for movementField.
Background technology
In nuclear power plant containment shell washing and filtering tapping equipment, for harmful mixing that containment superpressure is dischargedDedusting, needs installing gas filter; What in gas-filtering device, play a major role is venturi sprayMouth, current existing Venturi nozzle structure is more complicated, need to actively operate, and can not be applicable to radioactivity ringBorder, and can not meet higher instructions for use.
The venturi scrubber that ZL03204250.7 describes, this deduster is divided by the air water that forms Venturi tube main bodyThe collapsible tube being connected from device, with this moisture trap and be arranged on the inside and outside nozzle of this collapsible tube and feed pipeThe compositions such as road. Its groundwork principle is by the mixing of droplet and dusty gas, by soot dust granule and mistDrip collision sedimentation and carry out Purge gas. The venturi scrubber that ZL03204250.7 describes uses passive water supply installationMore complicated, inconvenient operation. It uses moisture trap to make complicated structure.
The venturi scrubber that ZL200620046996.0 describes, this deduster is by guider, extension fixture,Sealing packing device, base, hydraulic cylinder, depression bar, supporting seat, protective sleeve, interior centrum, aditus laryngis, contractionPipe, nozzle and supply channel form. Its groundwork principle is in the depression bar by being connected with hydraulic cylinder drivesMoving up and down of cone, reconciles the gap between aditus laryngis and convergent divergent channel and inner cone, reconcile flue gas flow andMagnitude of pressure differential between collapsible tube and convergent divergent channel, reaches efficient dedusting. ZL200620046996.0 describesVenturi scrubber complicated structure, operate more loaded down with trivial details, wayward, use passiveWater supply installation increases operation easier.
The Venturi nozzle that US5017331 describes, this Venturi nozzle is by collapsible tube, trunnion, double-deck imbibitionMouth, convergent divergent channel and baffle plate form. Its groundwork principle is to carry out droplet and dust by two liquid sucting portsMixing, make dust along with drop is got back in solution together, thereby reach dust removing effects. US5017331Two liquid sucting port position differences of Venturi nozzle of describing cause the two negative pressure difference, when Venturi nozzleWhen treating capacity changes, especially flow reduces, when throat's gas prompt drop is low, the liquid sucting port that pressure is higherNot only can not suck liquid, can also cause leaking of gaseous mixture, cause the decline of filter efficiency, performance is notStable.
Summary of the invention
The invention provides a kind of Venturi nozzle, can utilize the negative pressure forming in Venturi nozzle and do not use attachedThereby adding power set makes gas fully mix with cleaning solution the object that reaches dedusting.
A kind of Venturi nozzle, comprises nozzle body, pipette and baffle plate, and ancillary equipment has air inlet pipe, tankBody and cleaning solution; Wherein nozzle body is by collapsible tube, trunnion, convergent divergent channel and straight length overall structure from bottom to topBecome, convergent divergent channel and trunnion intersection circumferentially have uniform liquid sucting port, and liquid sucting port is connected with pipette, baffle plateBe connected with the top of straight length by pillar; Venturi nozzle is arranged in tank body and is connected with air inlet pipe, tank bodyInterior cleaning solution liquid level is higher than pipette height; Collapsible tube accelerates for gas, and angle of throat is 20-35 °,Length is 130-180mm; Length of throat is 35-50mm; Pipette is carried out imbibition by negative pressure, and quantity is3-8, diameter is 5-10mm, and length is 40-60mm; The angle of flare of convergent divergent channel is 10-18 °, lengthFor 200-240mm; Straight length fully merges for the cleaning solution after atomization and the dust in gas, and length is
600-800mm。
The course of work: when gas is filled with after air inlet pipe, gas enters the contraction of Venturi nozzle by air inlet pipePipe, collapsible tube plays the effect that gas accelerates, and gas flow rate reaches maximum at trunnion, and gas is high at trunnionSpeed flows and forms negative pressuren zone, thereby cleaning solution is sucked in Venturi nozzle from pipette; Gas at a high speed willThe cleaning solution sucking breaks into tiny dense droplet, and droplet is along with air-flow ejection forms spraying, in straight lengthWater smoke fully mixes with dust, and the droplet that has finally comprised dust is blocked by baffle plate, from the ejection of baffle plate surrounding,Thereby droplet is got back in cleaning solution, and then reached dust removing effects.
Beneficial effect: the present invention initiatively sucks liquid in pipette by negative pressure, makes dust granules and washingLiquid droplet fully mixes, and then reaches dust removing effects, does not need extra power set to make gas and cleaning solutionFully mix, structure is terse, easy to operate, practical. After testing, the present invention is for containment washingThe dust removing effects of filtering emission device can reach 99%.
Brief description of the drawings
Fig. 1 is the structural representation of Venturi nozzle of the present invention
Wherein: 1-collapsible tube, 2-trunnion, 3-pipette, 4-convergent divergent channel, 5-straight length, 6-baffle plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described
A kind of Venturi nozzle, comprises nozzle body, pipette and baffle plate, and ancillary equipment has air inlet pipe, tankBody and cleaning solution; Wherein nozzle body by collapsible tube 1, trunnion 2, convergent divergent channel 4 and straight length 5 from bottom to topEntirety forms, and convergent divergent channel 4 circumferentially has uniform liquid sucting port, liquid sucting port and pipette with trunnion 2 intersections3 welding, baffle plate 6 is by the top welding of pillar and straight length 5; Venturi nozzle be arranged in tank body withTracheae connects, and the cleaning solution liquid level in tank body is higher than pipette 3 height; Collapsible tube 1 adds for gasSpeed, angle of throat is 25 °, length is 150mm; Length of throat is 40mm; Pipette is undertaken by negative pressureImbibition, quantity is 6, and diameter is 5mm, and length is 50mm; The angle of flare of convergent divergent channel is 15 °, longDegree is 200mm; Straight length fully merges for the cleaning solution after atomization and the dust in gas, and length is
600mm。
The course of work: when gas is filled with after air inlet pipe, gas enters the contraction of Venturi nozzle by air inlet pipePipe 1, collapsible tube 1 plays the effect that gas accelerates, and gas flow rate reaches maximum at trunnion 2, and gas existsTrunnion 2 flow at high speed form negative pressuren zone, thereby cleaning solution is sucked in Venturi nozzle from pipette; At a high speedGas the cleaning solution of suction is broken into tiny dense droplet, droplet is along with air-flow ejection forms spraying,In straight length 5, water smoke fully mixes with dust, and the droplet that has finally comprised dust is blocked by baffle plate 6, from gearPlate 6 surrounding ejections, thus droplet is got back in cleaning solution, and then reach dust removing effects.
