Abstract
The invention relates to a Venturi tube type gas washer, which comprises a Venturi tube for introducing gas to be washed and a jet tube for introducing a liquid-phase washing medium, wherein the Venturi tube is provided with a head contraction section, a throat straight tube section and a tail expansion section from top to bottom sequentially; the jet tube for introducing the liquid-phase washing medium is fixed to the Venturi tube, a jet orifice of the jet tube corresponds to the throat straight tube section of the Venturi tube, and the jet tube jets the liquid-phase washing medium to the space of the throat straight tube section; the jet tube for introducing the liquid-phase washing medium comprises an inner jet tube and an outer jet tube; the inner jet tube passes through the tube wall of the head contraction section and is bent downwards, a jet orifice is positioned on a central line of the Venturi tube, and the inner jet tube jets the liquid-phase washing medium from top to bottom; and the outer jet tube passes through the tube wall of the throat straight tube section and jets the liquid-phase washing medium from outside to inside. The Venturi tube type gas washer has the advantages that a washing effect is improved obviously, and the processing efficiency and processing capacity of a single device are improved substantially, so the manufacturing cost and running cost are reduced.
Description
Technical field
The present invention relates to Drechsel system, relate in particular to a kind of venturi-type Drechsel system.
Background technology
The venturi-type Drechsel system mainly is made up of Venturi tube and jet pipe, and Venturi tube has collapsible tube, trunnion and enlarged tube three parts, and its principle is: the gas that contains solid or liquid impurity gets into collapsible tube; Flow velocity increases along pipe gradually, and water or other liquid are sprayed into by the trunnion place, is clashed into and atomizes by high velocity air; Grit in the gas contacts with drop and lubricated, and after the entering enlarged tube, flow velocity reduces gradually; Grit is bonded to each other; Particle is increased and be prone to remove,, obtain clean gas again through gas-liquid separation and gas solid separation.
The jet pipe of this washer has interior spray, sprays two kinds of versions outward, and interior spray is that jet pipe is put in the Venturi tube, and to trunnion space hydrojet, this jet pipe is only pipe, has only a shower nozzle, ejection umbrella liquid curtain, washing gas.Its shortcoming is: umbrella liquid curtain center density is big, and intensity is high, and is good to the clean result of gas; But liquid curtain periphery density is little, and intensity is low, and is bad to the clean result of gas; That is to say; The clean result of cylindric air-flow is weakened by middle mind-set periphery gradually, and the peripheral part of pressing close to the trunnion tube wall is almost nil, becomes the dead band.Outer spray is the periphery that many jet pipes is arranged in trunnion, and the jet pipe mouth of pipe passes through the trunnion wall, and to trunnion space hydrojet, its effect is just in time opposite with above-mentioned interior spray, and clean result is weakened to the center by periphery gradually, and the center of cylindric air-flow becomes the dead band.
Receive above-mentioned drawbacks limit; The disposal ability of existing venturi-type Drechsel system is all less; When gas flow is very big, has to use many washer parallel connections or, not only invest big with the higher wash mill of other cost (as: dynamic wave scrubber); Occupation of land is many, also is awkward and safeguards.Therefore, do not lean on simple up-sizing, how to improve the disposal ability of washer, become the problem of paying close attention in the industry.
Summary of the invention
For addressing the above problem, the present invention provides a kind of venturi-type Drechsel system, can increase substantially the separate unit washability.
Technical solution of the present invention is:
A kind of venturi-type Drechsel system comprises being used to feed Venturi tube that is washed gas and the jet pipe that is used to feed the liquid phase washing medium that said Venturi tube has head contraction section, throat's straight length and the afterbody expansion segment that is linked in sequence from top to bottom; Said liquid phase washing medium jet pipe is fixed on the Venturi tube; Throat's straight length of the corresponding Venturi tube of its jet sprays the liquid phase washing medium in this section space, said liquid phase washing medium jet pipe comprises inner nozzle and outer nozzle; Said inner nozzle passes through head contraction section tube wall; Downwarping, jet are positioned on the Venturi tube center line, spray the liquid phase washing medium from top to bottom; Said outer nozzle passes through the tube wall of throat's straight length, and ecto-entad sprays the liquid phase washing medium.
Said outer nozzle is made up of the feed liquor house steward who is linked in sequence, cloth pendular ring pipe, many hydrojet arms; Said cloth pendular ring pipe ring is around the periphery of Venturi tube, and is fixed on the Venturi tube through support bar, and said hydrojet arm circumferentially is uniformly distributed with; Pass through the tube wall of throat's straight length; Be the radiation convergent manner, the mouth of pipe flushes with throat straight length inwall, and ecto-entad sprays the liquid phase washing medium.
The jet of said hydrojet arm is inclined upwardly, with the gas flow formation angle of attack in the Venturi tube.
Said hydrojet arm is provided with valve, is used to regulate liquid phase washing medium injection flow.
Said hydrojet arm adopts flexible pipe.
Advantage of the present invention:
Owing to spray in adopting, spray composite construction outward, eliminated the dead band, clean result is significantly improved, and the treatment effeciency and the ability of unitary device increase substantially, thereby have reduced manufacturing cost and operating cost.
Description of drawings
Fig. 1 is the structure chart of this venturi tubular gas washer
Label among the figure: 1-head contraction section; 2-throat straight length; 3-afterbody expansion segment; 4-inner nozzle; 5-feed liquor house steward; 6-cloth pendular ring pipe; 7-hydrojet arm; 8-valve.
The specific embodiment
Referring to Fig. 1: this venturi tubular gas washer; Comprise and be used to feed Venturi tube that is washed gas and the jet pipe that is used to feed the liquid phase washing medium; Venturi tube has head contraction section 1, throat's straight length 2, the afterbody expansion segment 3 that is linked in sequence from top to bottom; The characteristics of this venturi tubular gas washer are that liquid phase washing medium jet pipe comprises inner nozzle and outer nozzle.
Said inner nozzle 4 passes through the tube wall of head contraction section 1, downwarping, and jet is positioned on the Venturi tube center line, sprays the liquid phase washing medium from top to bottom.
Said outer nozzle is made up of feed liquor house steward 5, cloth pendular ring pipe 6, many hydrojet arms 7; Said hydrojet arm 7 circumferentially is distributed on the periphery of throat's straight length 2, passes through the tube wall of throat's straight length 2, is the radiation convergent manner; The mouth of pipe flushes with throat straight length inwall, and ecto-entad sprays the liquid phase washing medium.
The jet of hydrojet arm 7 is inclined upwardly, and the gas flow formation angle of attack with in the Venturi tube can strengthen clean result.
Hydrojet arm 7 is provided with valve 8, but flexible liquid phase washing medium injection flow.
Hydrojet arm 7 adopts flexible pipe, is convenient to install, dismantle.
Spray in this washer adopts, spray composite construction outward, eliminated the hydrojet dead band, clean result is significantly improved, and the treatment effeciency and the ability of unitary device increase substantially, thereby have reduced manufacturing cost and operating cost.
