Abstract
A wind guide spray dust prevention device belongs to coal mine wind guide spray dust prevention device, which is characterized in that the spray device is installed in a wind guide institution composed of three guide cylinders. Two ends of each cylinder are respectively connected with the straight tube-shaped wind guide institution composed of an inlet wind guide cylinder and an outlet wind guide cylinder. Air enters from the inlet wind guide cylinder and goes out from the outlet wind guide cylinder. A high-pressure water pipe is arranged in the inlet wind guide cylinder, a team of ejecting nozzles are arranged in the high-pressure water pipe of the inlet wind guide cylinder, the water injection direction of the ejecting nozzles is of the same direction with the wind, the inlet wind guide cylinder also have a high-pressure water pipe, a team of ejecting nozzles are arranged in the high-pressure water pipe of the outlet wind guide cylinder, the water injection direction of the ejecting nozzles is of the same direction with the outlet air direction. The wind guide spray dust prevention device is of simple structure, can intake the majority air of the coal face, humid settle coal dust, at the same time water mist sprayed from the air outlet can form a large amount of fog circle which can surround dust sources and reach the target of dust prevention and greatly reduce face coal dust. The dust prevention rate is more than 90 percent.
Description
Technical field
The utility model belongs to the mine atomizing de-dusting apparatus, relates in particular to a kind of coal mine getting working face, fully-mechanized mining working atomizing de-dusting apparatus.
Background technology
In coal mine coal-winning machine or development machine operation process, can produce a large amount of coal dusts, this is the main dust source of getting working face.As the inside and outside spray method depositing dust with routine, the dustiness in the ambient air of mining machinery driver operating position is still very high, can reach more than 100～150mg/m3.Especially at fully-mechanized mining working, mining height is bigger, and the output height often is accompanied by large-area wall caving when the coal-winning machine coal cutting, and the dust concentration of work plane is higher, sometimes up to 600mg/m3, only depends on the interior external spraying of coal-winning machine can not satisfy the depositing dust requirement of fully-mechanized mining working.
According to home and abroad colliery coal-winning machine measurements for reduction and current research developments, the press water atomizing de-dusting is still the most effective current dust-removing method.Thereby select rational jet parameters, guiding dust laden air the flow direction, develop the equipment of realizing the high atomization degree and improve efficiency of seizing dust, be the main direction of current depositing dust research.
The utility model content
The purpose of this utility model provides a kind of simple in structure, the significant wind-guiding atomizing de-dusting apparatus of depositing dust dust removing effects.
The technical solution adopted in the utility model is as follows:
A kind of wind-guiding atomizing de-dusting apparatus, comprise atomization mechanism, it is characterized in that atomization mechanism is installed in the wind guiding mechanism of three guides compositions, the two ends of one guide connect the air intake guide respectively and the air-out guide is formed straight tubular wind guiding mechanism, air is entered by the air intake guide and is derived by the air-out guide, insert high-pressure intake pipe in the air intake guide, high-pressure intake pipe in the air intake guide is provided with one group of injection shower nozzle, the water spraying direction of injection shower nozzle with distinguished and admirable to identical, also have access to high-pressure intake pipe in the air-out guide, high-pressure intake pipe in the air-out guide is provided with one group of injection shower nozzle, and the water spraying direction of injection shower nozzle is identical with air-out direction.
Described three guides are the guide of rectangle for the internal diameter identical cross-section.
Described three guides are circular cylinder for the internal diameter identical cross-section.
The two ends of described guide are connected with the air-out guide with the air intake guide by flange respectively.
Described high-pressure intake pipe and wind-guiding barrel vertical junction are gone in air intake guide and the air-out guide.
Injection shower nozzle in air intake guide and the air-out guide is the long-range shower nozzle of high strength, make air intake form the negative pressure field when effect of one group of injection shower nozzle is water spray in the air intake guide, the effect of injection shower nozzle is to impel negative pressuren zone to increase in the air-out guide, also can make air outlet form large-area range of atomization simultaneously.The air intake guide sucks this wind-guiding atomizing de-dusting apparatus with the dust laden air around the mining machinery, the coal dust that swims is moistening sinking under the water smoke effect, the spray stream of air outlet ejection, and fogging degree is very high under the high wind speed effect, form large-area mist circle and surround the dirt source, realize the depositing dust purpose.
When using this wind-guiding atomizing de-dusting apparatus, original device of mining machinery and parts do not change, and still keep former inside and outside spraying system, and debugging does not influence normal digging production basically when this device is installed.
The beneficial effects of the utility model are, this wind-guiding atomizing de-dusting apparatus is simple in structure, the negative pressure that can utilize first group of injection shower nozzle to form sucks most of face air in the guide, moistening sedimentation coal dust, the spray stream of air outlet ejection simultaneously, fogging degree height under the high wind speed effect, form large-area mist circle and surround the dirt source, realize the depositing dust purpose, greatly reduce the coal dust of work plane, dust reduction rate reaches more than 90%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the cut-away section structural representation of the utility model embodiment;
Fig. 2 is that the A of Fig. 1 is to the cut-away section structural representation.
The specific embodiment
As Fig. 1 and 2, this wind-guiding atomizing de-dusting apparatus is by air intake guide 1, air-out guide 5 and the guide 4 that is positioned at the two are formed wind guiding mechanisms, three guides are rectangular cylinder, be about 4000mm, wide about 600mm, high about 350mm, the three connects by flange, air is entered by the air intake guide and is derived by the air-out guide, insert high-pressure intake pipe 2 in the air intake guide, high-pressure intake pipe and wind-guiding barrel vertical junction are gone in air intake guide and the air-out guide, high-pressure intake pipe in the air intake guide is provided with one group of injection shower nozzle 3, and the water spraying direction of injection shower nozzle to identical, also has access to high-pressure intake pipe 6 with distinguished and admirable in the air-out guide, high-pressure intake pipe in the air-out guide is provided with another group injection shower nozzle 7, and the water spraying direction of injection shower nozzle is identical with air-out direction.
Open the injection shower nozzle and spray water, the wind speed of air intake is about 8.5m/s, and the suction air volume of guide is about 80m
3/ min sucks this device with the dust laden air around the mining machinery, and the coal dust that swims is moistening sinking under the water smoke effect.The spray of air outlet ejection, fogging degree is very high under the high wind speed effect, forms large-area mist circle and surrounds the dirt source, realizes the depositing dust purpose.This device gross weight is about 400kg, when machine maintenance, can easily ventilating duct integrally be hung on face roof, also this device can be taken apart from flange, and two people can remove.
