Abstract
The utility model belongs to the ventilation and dust control technique of the tunnel and underground engineering. A provided water screen duster forms an atomizing storehouse which is composed of the outer wall of a high pressure water pipe (3) and the inner wall of a cylindrical steel pipe (4), the high pressure water pipe (3) in the atomizing storehouse is provided with a spout hole (7), the atomizing storehouse is connected with a high pressure air feeder (10), and the outer wall of the atomizing storehouse is provided with a jet orifice (5). The duster which is provided by the utility model can utilize the high pressure water pipe and the high pressure water pipe which are used in tunnel and underground engineering construction directly, the operations are convenient, the installment is easy, and the dusting effect is good.
Description
Technical field
The utility model belongs to the ventilating dust-removing technology of tunnel and underground construction, mainly proposes a kind of screen collector.
Background technology
In tunnel and underground engineering construction, boring and bursting work, concrete spraying operation dress quarrel and quarrel stone are had bad luck operation, the operation of vehicle; Operation meetings such as the excavation pneumatically placed concrete operation of development machine produce a large amount of dust.Dust meeting serious harm health, in the dust that the people sucks, the dust of the above particle diameter of 10 μ m, heavy being attached in nasal cavity and the last respiration tracheae discharged by phlegm, and the dust of 10～5 μ m particle diameters enters the deep bronchus and sinks attached.And the fine particle of 2～0.5 μ m particle diameters can arrive pneumonocyte, causes the pathology of lung and surrounding tissue thereof so that form symptoms (so-called silicosis) such as oxygen undersupply, expiratory dyspnea in fibrous tubercle, lung's hardening, the blood.The dirt silicosis also is easy to concurrent other disease in case form to be difficult to cure, PD is also arranged after PFT completely lose and dead example.So must take the dedusting technology measure in tunnel and underground engineering construction, the control dust concentration is under admissible concentration, to ensure operating personnel's health.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of screen collector, in order to the dust that tunnel and underground engineering construction produced is removed.
The utility model is finished the technical scheme that its invention task taked: constitute the atomizing storehouse by the outer wall of a high-pressure water pipe and the inwall of a steel cylindrical tube, high-pressure water pipe in the atomizing storehouse has hole for water spraying, water under high pressure is sprayed in the atomizing storehouse, the atomizing storehouse links to each other with high-pressure pipe, make high-pressure blast enter in the atomizing storehouse and water is atomized in the storehouse that atomizes, the outer wall in atomizing storehouse has spray-hole, atomized water is ejected in tunnel and the underground construction operating environment by spray-hole forms water curtain.
High-pressure water pipe has stop valve and relief valve, and high-pressure pipe is provided with stop valve, and the atomizing storehouse is provided with relief valve.
The course of work of the utility model deduster is: link to each other with the constructing tunnel high-pressure water pipe with the high-pressure water pipe of flexible pipe with deduster, the high-pressure pipe of deduster links to each other with the constructing tunnel high-pressure air hose, water is ejected in the atomizing storehouse by atomizing storehouse inner high voltage water pipe hole for water spraying and is atomized under the distinguished and admirable effect of high pressure, spray-hole by the atomizing storehouse is ejected in the tunneling operation environment and forms water curtain, thereby dust is caught in water smoke drop and dust collision.
The deduster that the utility model proposes can directly utilize used high-pressure water pipe and high-pressure pipe in tunnel and the underground engineering construction, and is easy to operate, is easy to install and good dedusting effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, water supply hose, 2, stop valve, 3, high-pressure water pipe, 4, steel pipe, 5, spray-hole, 6, relief valve, 7, hole for water spraying, 8, air induction hose, 9, the air inlet stop valve, 10, high-pressure pipe, 11, atomizing storehouse relief valve.
The specific embodiment
The embodiment that provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, constitute the atomizing storehouse by the outer wall of a high-pressure water pipe 3 and the inwall of a steel cylindrical tube 4 in the utility model deduster, high-pressure water pipe 3 in the atomizing storehouse has hole for water spraying 7, the atomizing storehouse links to each other with high-pressure pipe 10, the outer wall in atomizing storehouse is to have spray-hole 5 on the wall of steel cylindrical tube 4, and all the other positions, storehouse that atomize except that hole for water spraying and spray-hole are enclosed construction.High-pressure water pipe is provided with stop valve 2 and relief valve 6, and high-pressure pipe is provided with stop valve 9, and the atomizing storehouse is provided with relief valve 11.
During use, high-pressure water pipe 3 is communicated with the high pressure water route of job site by water supply hose 1, and high-pressure pipe 10 is connected with the high pressure wind path.
Claims (2)
1, a kind of screen collector, it is characterized in that: constitute the atomizing storehouse by the outer wall of a high-pressure water pipe (3) and the inwall of a steel cylindrical tube (4), high-pressure water pipe (3) in the atomizing storehouse has hole for water spraying (7), the atomizing storehouse links to each other with high-pressure pipe (10), and the outer wall in atomizing storehouse has spray-hole (5).
