Background technique

The Chinese utility model patent for now retrieving a Publication No. CN205667773U discloses a kind of workshop spray Leaching formula waste gas dust-removal device, including waste gas delivery pipeline, waste gas dedusting tank, water pipe, water pump, base support and waste water treatment box；Institute State the top right side central location that waste gas dedusting tank is arranged in waste gas delivery pipeline；The waste gas delivery pipeline is provided with double end discharge Mouthful；The lower end of waste gas delivery pipeline, and double end discharge outlet and the horizontal seamless welding of waste gas delivery pipeline is arranged in the double end discharge outlet； The top of waste water treatment box is arranged in the waste gas dedusting tank, and waste gas dedusting tank is concordant with waste water treatment box right end face designs And it welds；The waste gas dedusting tank is provided with spray tube, guide plate, blower fan, motor and bottom plate；Water injection valve on clear water reserviors is used In the gas effect that addition clear water and discharge are clean.

But the bottom of the dust-extraction unit is provided with the blower fan for promoting exhaust gas and ejecting liquid convection current, needs to remove in exhaust gas The device of mating driving blower fan in dirt tank, manufacture is difficult, unreasonable structure.

Utility model content

The purpose of the utility model embodiment is to provide a kind of workshop dust-extraction unit, solves at least to a certain extent State one of technical problem, have the advantages that it is structurally reasonable, facilitate manufacture.

The utility model first aspect provides a kind of workshop dust-extraction unit, comprising:

Spray column is provided with spraying mechanism；

Foul water tank is located at spray column lower end and collects sewage；

Water inlet pipe leads in spray column, is connected to spraying mechanism；

Waste gas delivery pipeline, for house exhaust to be sent into spray column；

The spray column includes spray chamber, and the side of the spray chamber is provided with air inlet, the side wall of the spray chamber into The opposite side of stomata is provided with return passage, and the return passage includes the refluxing opening towards spraying mechanism, and the air inlet tilts upward The refluxing opening of air inlet opposite side in towards spray chamber.

By using above-mentioned technical proposal, house exhaust reaches air inlet from waste gas delivery pipeline, enters spray by air inlet It is moved obliquely when drenching chamber, forms convection current with the liquid that spraying mechanism sprays, promote contact of the house exhaust with ejecting liquid, mention Height spray efficiency；House exhaust does not enter refluxing opening by the part of ejecting liquid taken away, and is sent to again from return passage reflux Spraying mechanism below, and ejecting liquid convection current improves the dust removing effects to house exhaust；No setting is required in spray chamber blower fan Promote gaseous exchange, spray column is simple to manufacture, and cost reduces, structurally reasonable.

Further, the air inlet is towards the lower end of refluxing opening.

By using above-mentioned technical proposal, house exhaust not by the part of ejecting liquid taken away from the lower end of refluxing opening into Enter return passage, the rebound by the chamber interior walls that flow back is oriented to, and is delivered in spray chamber above refluxing opening, with ejecting liquid pair Stream, makes grit land with drop.

Further, the return passage is provided in the reflux tilted upward towards spraying mechanism in the upper end of refluxing opening Wall.

By using above-mentioned technical proposal, the house exhaust by the chamber interior walls rebound guiding that flows back is along reflux inner wall direction spray Mechanism flowing is drenched, the grit in house exhaust is adsorbed leukorrhagia by the ejecting liquid that spraying mechanism sprays.

Further, the return passage is circle along the cross section of spray chamber circumferential direction.

By using above-mentioned technical proposal, the return passage of circular cross section is equal in guiding of the different location to house exhaust It is even, so that return passage is formed the steady air flow flowed towards spraying mechanism.

Further, the inner wall upper end of the spray chamber is provided with venthole, and the venthole is diagonally downward towards spray It is intracavitary, exhaust pipe is provided with outside the venthole.

By using above-mentioned technical proposal, venthole diagonally downward, reduces the probability that grit is discharged with gas, improves discharge The cleannes of gas, it is structurally reasonable.

Further, the spraying mechanism includes the water feeding base being connected to water inlet pipe, and is rotatably connected on water feeding base Water spout, the water spout includes connecting tube and spray head, the connecting tube and water feeding base rotatory sealing, in the connecting tube It is fixed with pivoting leaf, several spray apertures being uniformly arranged are provided on the spray head.

By using above-mentioned technical proposal, when shower water passes through connecting tube from water feeding base, shower water causes pivoting leaf Impact makes pivoting leaf have the tendency that rotation, drives connecting tube rotation, and the water droplet sprayed from spray apertures is under the influence of centrifugal force It is spread far from center of rotation, expands spray area, and the lower of rotation path can form spray cascade, reduce between spraying Gap improves drop to the adhesiving effect of grit.

Further, there are four the spray equipment is uniformly distributed in a ring on the top of spray chamber.

By using above-mentioned technical proposal, the equally distributed spraying mechanism of annular expands spray area, and reduces The generation at dead angle is sprayed, spray efficiency is improved.

Further, the water feeding base includes the flow pipe that the Five-way tube being connected to water inlet pipe is connected to Five-way tube, described The water discharging direction of flow pipe straight down, the connecting tube and flow pipe rotatory sealing.

By using above-mentioned technical proposal, it is connect using Five-way tube with water inlet pipe, uniform fluid flow is shunted, flow pipe and five Water discharging direction is adjusted to straight down after siphunculus connection, structurally reasonable, simple installation.

In conclusion the utility model embodiment has the advantages that

First, return passage is oriented to house exhaust, increase the ejecting liquid that house exhaust and spraying mechanism spray Contact probability, improve spraying effect, return passage and spray column are integrally formed when processing, easily manufactured；

Second, the spray area of the spraying mechanism of rotation injection is big, gap when spray is smaller, sprays high-efficient.
