Description
Technical field
The invention belongs to technical field of operation, is related to a kind of separator, particularly a kind of wet type polishing dust deduster.
Background technology
Wet dust removal is fully contacted with dusty gas using cleaning solution (generally water), and grit is washed and makes gas
The method of body purification.Wet dust removal efficiency high, wet scrubber is simple in construction, and low cost, floor space is small, operates maintenance side
Just, particularly suitable for processing high temperature, high humidity, inflammable, explosive dusty gas.
Chinese patent literature discloses a kind of wet type polishing deduster (application publication number CN106695565A), utilizes air-flow
By forcing aquatic products unboiled water to be spent between dividing plate and liquid level during wind gap, and then spray mixes with air-flow.Because air current flow makes
Water produces wave, and dust and accumulation of impurities cause liquid surface height controlling precision extremely low on liquid level, and then causes between wind
Air flow rate is unstable at gap, and spray amount is also unstable so that moisture content is inconsistent in air-flow.
The content of the invention
The present invention proposes a kind of wet type polishing dust deduster, the technical problem to be solved in the present invention be how to improve it is wet
Formula polishes dust deduster moisture content uniformity.
The technical problems to be solved of the present invention can be realized by following technical proposal：This wet type polishes dust deduster
Including casing, water inlet pipe and the horizontally disposed Venturi tubes of Duo Gen, the inner chamber posterior region of casing is dedusting chamber, on front side of inner chamber under
Portion region is dust-collecting cavity, and actuation holes are provided with the side wall of dust-collecting cavity；Dust-collecting cavity and dedusting chamber pass through baffle interval, dividing plate and casing
Communicating passage is left between the bottom surface of inner chamber；More Venturi tubes are horizontally arranged, and Venturi tube is fixedly connected with dividing plate, venturi
Pipe makes dust-collecting cavity be connected with dedusting chamber；The neck of Venturi tube has an inlet opening, the inlet opening in more Venturi tubes with
Water inlet pipe is connected；This wet type polish dust deduster using when need to hold liquid medium in the intracavity bottom of casing, liquid is situated between
The liquid level of matter is located between root edge and the Venturi tube of dividing plate.
Compared with prior art, communicating passage is in sealed condition, i.e. air-flow during the operation of this wet type polishing dust deduster
Can not be from communicating passage by the way that but the dust for being deposited in dust-collecting cavity can enter dedusting chamber by communicating passage, dust accumulation is existed
Together, it is convenient to clean.Communicating passage also enables dust-collecting cavity and the liquid medium of dedusting chamber mutually flow, so make dust-collecting cavity and
The liquid medium liquid level of dedusting chamber is essentially identical.
During the polishing dust deduster operation of this wet type air-flow from Venturi tube by the way that liquid medium passes through water inlet pipe and enters text
In venturi, it is achieved in water and is mixed with air-flow.During water is with air motion, water is crashed to pieces into tiny water smoke, and tool
There is the advantages of water smoke is well mixed with air-flow.
Water inlet pipe is connected with running water pipe or is connected with storage tank, it is ensured that water supply pressure is stable and output is steady
It is fixed, thereby guarantee that water smoke content is consistent in air-flow.

Dust-collecting cavity 1d and dedusting chamber 1a are spaced by dividing plate 4, and dividing plate 4 is vertically arranged, dividing plate 4 and the bottom surface of the inner chamber of casing 1
Between leave communicating passage 5.The inner chamber bottom plate 1g of casing 1 is obliquely installed, and inner chamber bottom plate 1g rear end is less than front end, so that
It can be slided naturally to dedusting chamber 1a directions after the dust accumulation settled in dust-collecting cavity 1d, and then the powder settled with dedusting chamber 1a
Dirt is packed together, and is convenient to clean dust.
The quantity of Venturi tube 3 is more, and Venturi tube 3 is horizontally disposed, dividing plate 4 and more of the inner chamber of casing 1 Venturi tube 3
Horizontal Tile arranges, and the quantity that Figure of description provides Venturi tube 3 is 5, and the air inlet port of adjacent Venturi tube 3 is interdependent
Lean on, the overall width of 5 Venturi tubes 3 is identical with the width of dividing plate 4.Venturi tube 3 has one in coniform intake section, one is in
The neck of straight tube-like and in coniform outlet portion；Neck has inlet opening；Inlet opening in more Venturi tubes 3 with water inlet
Pipe 2 is connected；The Venturi tube 3 of the structure is not easily blocked.The taper in outlet portion is 1:8~1:15；Applicant passes through big gauge
Calculate and experiment draws the taper for first determining outlet portion, adjusting to readaptability the length in outlet portion just can efficiently control water atomization
Degree and water smoke and air-flow mixing uniformity；The length in outlet portion and the diameter ratio of neck are 5~6.5.Above-mentioned use is more
The structure of root Venturi tube 3 is higher with dust catching efficiency compared with using a thicker Venturi tube 3, water atomization degree height,
Water smoke mixes evenly with air-flow, more compact structure.
Venturi tube 3 is located in dedusting chamber 1a, is provided with dividing plate 4 and the position of Venturi tube 3 one-to-one corresponding and size and text

Structure significantly improves the mounting stability of Venturi tube 3, avoids producing abnormal sound during wet type polishing dust deduster operation.Thus may be used
Know do not have Venturi tube 3 and appurtenances in dust-collecting cavity 1d, ensure air current flow smoothness, especially avoid producing flowing
Vortex and flow dead, and then it is effectively guaranteed dust-collecting cavity 1d dust catching efficiency.
This wet type polish dust deduster using when need to hold liquid medium 7, liquid medium 7 in the intracavity bottom of casing 1
Liquid level 8 be located between root edge and the Venturi tube 3 of dividing plate 4.Liquid medium 7 is water or detergent solution.Dust-collecting cavity 1d's
Blowdown discharge outlet 9 is provided with side wall, blowdown discharge outlet 9 is located between root edge and the Venturi tube 3 of dividing plate 4, i.e., by controlling liquid
The actual height of control liquid level 8 of maximum height in face 8.
This wet type polishing dust deduster also includes control circuit, wind pressure sensor and alarm, and wind pressure sensor is set
In dedusting chamber 1a, control circuit according to the signal of wind pressure sensor control alarm whether alert.Specifically,
When Venturi tube 3 blocks, air pressure changes in dedusting chamber 1a, and then is detected and produced according to setting by wind pressure sensor
Signal, in other words, the alarm alert then blockage phenomenon of notification portion Venturi tube 3, so people can and
When safeguarded, ensure dust catching efficiency.
By illustrating that this wet type polishes the application of dust deduster, the effect of various pieces is further illustrated and beneficial to effect
Fruit.Polishing wheel is arranged in dust-collecting cavity 1d, and blower fan is provided with air outlet 1b, and fan operation makes air enter from actuation holes 1e,
Discharged after dust-collecting cavity 1d, Venturi tube 3, dedusting chamber 1a from air outlet 1b；It is consequently formed air-flow.Air-flow passes through Venturi tube 3
When, water mixes with air-flow and current smash into the globule and water smoke and the globule and water smoke by air-flow and uniformly mixed with air-flow.
Air-flow containing dust, the globule and water smoke is after water removal plate 1c separation, and clean air is discharged from air outlet 1b, powder
Dirt be mixed in current downwards trickling and the intracavity bottom of casing 1 assemble, dust natural subsidence on the inner chamber bottom plate 1g of casing 1,
Unnecessary water is discharged through blowdown discharge outlet 9；Water can be miscellaneous by the part floated in dust-collecting cavity 1d on liquid medium 7 in the process
Matter washes away, and significantly reduces the impurity to be floated in dust-collecting cavity 1d on liquid medium 7, and then reduces Venturi tube 3 and block possibility.
