Abstract

A water-curtain wash-off dust collector comprises an air inlet pipe (1), a water drift plate (2), a water overflow tank (3), a top-spray pipe (4), an exhaust pipe (5), a water washing chamber (6), a lower spray pipe (7), a water storage tank (8), a maintenance door (9), a partition board (10), a valve (11) and a water pump (12), wherein, the air inlet pipe (1) is a rectangular increasing coupling which is arranged horizontally, and forms a closed dust collecting and exhaust passage with the water washing chamber (6) and the exhaust pipe (5); the water storage tank (8) with the valve, the water pump and a water circulation pipeline is arranged below the water washing chamber; the water overflow tank (3) and the top-spray pipe (4) are arranged at the upper part of the water washing chamber; the water drifting plate (2) is connected to the lower part of the water overflow tank (3); and an arc-shaped curved plate is arranged at the lower end of the water drift plate. The dust remover is novel dust collecting equipment for treating dust cloud in a water washing manner during the sand blasting technological process. The dust remover has the function that dust-laden tail gas subject to the primary treatment by a cyclone dust extractor is blown into a working area of the dust remover for washing and filtering, so that tail gas exhausted into the air reaches the national environmental protection standard without a chimney, the operation is safe and reliable, the maintenance is convenient, and the equipment cost is reduced.

Description

Cascade rinsing type deduster

Technical field

The utility model is a kind of novel dust removing equipment that the mode that washes with water used in the blasting craft flow process is handled cloud.

Background technology

Existing dry collector dust removing effects is not good, and particularly filter cartridge dust remover needs artificial regularly deashing and periodic replacement, maintenance cost height.

Summary of the invention

The purpose of this utility model provides a kind of efficiency of dust collection height, air drag wet scrubber little, easy to maintenance.

Cascade rinsing type deduster is a kind of novel dust removing equipment that the mode that washes with water used in the blasting craft flow process is handled cloud.Its effect is that the washing and filtering processing is carried out in the working region of sending into this equipment by blower fan through the dust-laden tail gas of cyclone dust collectors preliminary treatment, can make to enter aerial tail gas and reach national environmental standard, not need chimney, safe and reliable, easy to maintenance, reduced equipment cost.

Its operation principle is: water pump injects the spilling water groove to water continuously, make its overflow, form the water curtain of waterfall shape on dropping plate, when dust-contained airflow contacted with moisture film, dust promptly was captured, fall into tank, the dust that is not captured enters the washing chamber from the bottom of dropping plate and is repeatedly washed under the effect of taking out (sending) general mood stream, is still dashed to tank by water, the water droplet of carrying secretly in the air-flow is blocked by dividing plate 10, and clean air-flow enters atmosphere.

Water in the tank can be recycled, and the water supply trunk line is provided with along overflow water slot length direction.On trunk line, branch pipe(tube) is set at regular intervals, supply water to the overflow tank.Prevent that for overflow is all even floating thing from flowing to dropping plate, be provided with dividing plate in the overflow tank, make water flow to dropping plate from the lower partition.

For ease of indoor cleaning, top, body rear portion, chamber is provided with AD.

Water injection system is to clean the key facility of cloud.The flow direction of water spraying direction and cloud is opposite, and the interval between the nozzle guarantees the water smoke overlaid of ejection, makes all dust-contained airflows all obtain cleaning.

Technique effect of the present utility model is that it has the efficiency of dust collection height, and resistance is little, and the cleaning works amount is little, advantage easy to maintenance.
