Abstract

The utility model discloses a wet dust collector for mines, which consists of a casing, a sprayer, a dust filter, and a dust water collector. The device is connected with the upper negative pressure air barrel of a tunneling machine so as to effectively improve the mine dustfall rate. The utility model has such characteristics as compact structure, small noise, high dedusting efficiency and large ventilation volume; moreover. And the utility model is easily used with the tunneling machine and the work surface ventilation system, with the aim to improve the mine dustfall rate, thereby the utility model is applicable to the tunneling work surface of the coal mine with high-medium concentration gas, and also to the tunneling work surface of the non-coal mine.

Description

Mining wet scrubber

Technical field:

The utility model belongs to mining and uses equipment, relates in particular to a kind of cleaner that development machine uses that is matched in.

Background technology:

In the prior art, the deduster that uses under the coal mine, home products mostly are the direct water spray dirt mode of going out, and the shortcoming of this mode is that water supply volume is big, can not make dust fully moistening, and the air moisture content of discharge is big, and less dust is discharged with air, and dust removing effects is poor.And similar external product adopts is the totally enclosed type dust filter unit, and shortcoming is that drafting efficiency is poor, is not suitable for China's coal-bed gas concentration height, characteristics that ventilation is big, must the frequent clean dust filter unit, and labor strength is big.

Summary of the invention:

The purpose of this utility model provides the mining wet scrubber after a kind of the improvement, can effectively improve the mine dust dust reduction rate.

The purpose of this utility model is achieved in that

The utility model is made up of shell, sprayer, dust filter unit, dust water collector;

Described shell is welded by steel plate, is cydariform, and an end is an air intake, and the other end is an air outlet;

Near the air intake place, D type porous sprayer is installed in the housing;

At inner walls and housing middle part, symmetry is installed some dust filter units, one side the loose guiding gutter that is provided with of dust filter unit, the facade of dust filter unit is vertical with horizontal plane, keep certain angle with the air intake direction, dust filter unit is separated into " it " font with the space in the housing;

" V " type header tank is arranged at the bottom of described guiding gutter.

Beneficial effect: the utlity model has characteristics such as compact conformation, noise is little, efficiency of dust collection is high, ventilation is big, easier and development machine and face-airing system support, can effectively improve the mine dust dust reduction rate, be specially adapted to high, normal, basic concentration fiery colliery driving face, also can be used for the non-coal mine driving face.

Description of drawings:

Fig. 1 is a structure diagram of the present utility model;

Fig. 2 is the left view of Fig. 1.

Described in detail below in conjunction with accompanying drawing.

As shown in the figure:

One end of cydariform deduster 4 is an air intake, the other end is an air outlet, air outlet is connected with air-introduced machine, close air intake place in the deduster 4, D type porous sprayer 1 is installed, at deduster 4 inwalls and middle part, symmetry is installed some dust filter units 2, dust filter unit 2 loose one side are provided with guiding gutter 5, the facade of dust filter unit 2 is vertical with horizontal plane, keeps certain angle with the air intake direction, and dust filter unit 2 is separated into " it " font with the space in the deduster 4, " V " type dust water collector 3 is arranged at the bottom of guiding gutter 5, and the sewage that dust filter unit 2 is collected flows into " V " type dust water collector 3 behind guiding gutter 5.

During work, air-introduced machine sucks the air of dust pollution in the deduster 4, built-in atomizing device 1 with airborne dust fully moistening after, speed by about 3 metre per second (m/s)s enters, the part air is by dust filter unit 2, dust water is bonded on the dust filter unit 2, the air that remainder carries dust water is walked around dust filter unit 2 and is continued " it " fonts and advance, because action of centrifugal force, the dust water that weight is bigger in the air is got rid of on dust filter unit 2, behind 3-4 " it " font, the dust more than 95% in the air can be got rid of on dust filter unit 2.Be bonded in dust on the dust filter unit through the effect of wind-force, gravity, enter discharge in the dust water collector 3 by guiding gutter 5, bigger dust granules is bonded on the dust filter unit, and accumulating to influences dust filter unit ventilation 30% when above, and available water rinses out.
