Abstract
The utility model discloses an underground parallel jet-flow dust removal system which is composed of a water storage tank, a water pump, pipelines, fluid flow meters, a parallel type ejector and a filter tank. The parallel type ejector comprises two ejector structures. Each ejector structure is provided with a nozzle, a suction chamber, a suction pipe and a throat pipe inlet section part. The nozzle, the suction chamber, the suction pump and the throat pipe inlet section part of one ejector structure are separated from the nozzle, the suction chamber, the suction pump and the throat pipe inlet section part of the other ejector structure through an inner wall between the two ejector structures. The water pump, the fluid flow meters, the parallel type ejector and the filter tank are connected into a loop through the pipelines. Water is pumped into the inside of the ejector from the water storage tank through the nozzles by the water pump, outer dust is driven to flow into each suction chamber from each suction pipe, the dust and the water are mixed in the second half portion of each throat pipe, fluid after being mixed flows into the filter tank through one of the pipelines, and water after being filtered flows into the water storage tank and is reused through the water pump. The underground parallel jet-flow dust removal system is relatively independent and simple in structure, easy to operate, and suitable for being used for underground dust removal.
Description
Technical field
The present invention relates to injector, particularly a kind of parallel jet dust removal system for the down-hole.
Background technology
Injector is to utilize the ejector action of one high pressure, high-octane flow type pump with injection to suck the device of another burst low pressure, low-yield fluid.In many places, all to use injector.At present, for traditional injector, general injector all is separate unit, and needs under many circumstances to increase injection volume, and the separate unit injector can not meet the demands.Utilize this parallel injector to extract the coal dust of down-hole, the air of purification down-hole improves underground labour's working environment.Purpose of the present invention overcomes the above problems exactly.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of simple in structure, simple to operate, downhole parallel jet dust removal system that can satisfy dust removing down-hole.
In order to achieve the above object, the technical scheme of the present invention's proposition is:
Downhole parallel jet dust removal system is comprised of reservoir, water pump, pipeline, first liquid flow meter, second liquid flow meter, parallel injector, filtering ponds; Parallel injector comprises the first injector and the second injector of being separated by inwall, the first injector comprises the first nozzle, the first suction chamber, the first suction pipe, the first trunnion entrance, and the second injector comprises second nozzle, the second suction chamber, the second suction pipe, aux. venturi entrance; Inwall is in the cut-off of trunnion first half, and described the first injector comprises that also the trunnion first half is positioned at the part of inwall one side, and described the second injector comprises that also the trunnion first half is positioned at the part of inwall opposite side; The first nozzle, the first suction chamber, the first suction pipe, the first trunnion entrance are separated in parallel injector one side by inwall, and second nozzle, the second suction chamber, the second suction pipe, aux. venturi entrance are separated at parallel injector opposite side by inwall; Reservoir, water pump, first liquid flow meter, second liquid flow meter, parallel injector, filtering ponds connect into a loop by pipeline.
The first suction chamber of described parallel injector, the second suction chamber, the first trunnion entrance, aux. venturi entrance and trunnion partly are all semicircular structure.
In sum, downhole parallel jet dust removal system of the present invention does not have complicated structure, satisfies the requirement that coal dust is extracted in the down-hole, therefore is easy to realize; Since simple in structure, make and keep in repair also fairly simple, convenient.
