The present invention relates to a kind of mine dedusting equipment, be specifically related to a kind of convergent-divergent throttling acceleration type pneumatic dust removal system.
Background technology
Pneumoconiosis is a kind of occupational disease that is caused by dust, ranks the first in the incidence of disease of all occupational diseases of China, and the coal industry pneumoconiosis accounts for 49% of national pneumoconiosis.Pneumoconiosis Patients the lighter can cause the multiple complications such as breathing problem, pulmonary tuberculosis, and the severe one disability is even dead.The numeral of announcing according to the Ministry of Public Health shows, annual Pneumoconiosis disease reaches 5.7 ten thousand examples, and is ascendant trend year by year.An investigation of supervising security bureau, Chinese Professional safety and Health association of the All-China Federation of Trade Unions according to national colliery shows: dust concentration severe overweight under most coal mine, wherein the most serious superstate standard is more than 300 times, have every year a large amount of coal miners to suffer from pneumoconiosis, and because of the number of Death from Pneumoconiosis be the twice of security incident death toll.
At present the dust suppression mainly taked of China's coal-mine down-hole is the spray sprinkler dedusting, and the spray sprinkler dedusting method divides again two kinds of low pressure atomizing and high-pressure fogs.Its weak point is respectively: 1, low pressure atomizing dedusting, and water pressure is little, and waste water resource can't effectively reduce less coal dust, dust granules, to the efficiency of dust collection less than 70% of respirable dust.2, high-pressure fog dedusting, need to make electrical installation as power source at the product dirt pits, impels high-pressure pump work, this method input cost is large, easily causing security incident has strict requirement to supply line, equipment, and can not form complete dedusting system, and the dedusting blind spot is more.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of safer reliable, stable performance, easy maintenance, the convergent-divergent throttling acceleration type pneumatic dust removal system with extensive practical value.
A kind of convergent-divergent throttling acceleration type pneumatic dust removal system, comprise the diffuser cover body that is truncated cone-shaped, in axial direction be provided with at least two pneumatic speedup dedusting mechanisms of group in the cavity of described diffuser cover body, described pneumatic speedup dedusting mechanism comprises near the Rotary dust collecting body of diffuser cover body portlet and the source of the gas actuating unit that joins with Rotary dust collecting body power.
Described Rotary dust collecting body and source of the gas actuating unit include streamlined cover body, the large end place of two streamlined cover bodies is connected on support in being located at the diffuser mask body intracavity mutually, extend to diffuser cover body two-port place at the small end place, the interface of described Rotary dust collecting body is provided with impeller, the interface of source of the gas actuating unit is provided with air motor, and the axis of rotation of described air motor is connected on impeller.
Also be arranged with stator on the streamlined cover body of described source of the gas actuating unit.
The coaxial current collector that is provided with in the portlet place of described diffuser cover body.
The import department of described current collector is equipped with filter screen.
Also be provided with pressure inlet in the inner chamber at the portlet place of described diffuser cover body, described pressure inlet pipeline is connected on the outlet branch road of air motor, on this outlet branch road, choke valve is installed.
Also be provided with water spout in the inner chamber at the portlet place of described diffuser cover body, the water pipe of described water spout is connected on the outlet branch road and inlet channel of air motor simultaneously.
The present invention adopts the above air motor in two Lu Huoer roads to rotate in the diffuser cover body as the power source drives impeller, and dust gas axially enters from current collector, by impeller, obtains energy, thereby axially constantly discharges and reach the dedusting purpose.The diffuser cover body (conversion volume) of the truncated cone-shaped of the present invention's design can effectively be accelerated gas flow rate.Utilize in addition the gas of air motor outlet to import pressure inlet in diffuser, can improve its inner gas flow rate, accelerate the axial discharge of gas, play the purpose of energy efficiency.Place is equipped with water injector in diffuser cover body portlet, utilizes simultaneously the gas of air motor outlet as excitaton source, reaches the purpose of the water spray wet type depositing dust of calming the anger, and efficiently solves dust serious problems under coal mine.Apparatus of the present invention are safe and reliable, stable performance, and efficiency of dust collection is high, and easy maintenance has practical value widely.
