Description

Water mist spraying device for dust isolation, dust fall and waste gas reduction of cavern

Technical Field

The utility model relates to an crossing hole room traffic and construction field, in particular to are a hole room dust separation, dust fall, subtract water smoke injection apparatus of waste gas.

Background

The existing caverns are in a four-way and eight-way structure, and have intersection conditions, and most of tail gas formed by vehicles in driving or waste gas and dust generated in the construction of cavern excavation and the like are pumped and discharged by a fan, but the construction of long caverns, large traffic volume and underground cavern groups is difficult to control, so that the environmental protection requirements cannot be met, and the health of pedestrians and workers is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the above not enough, provide a dust separation, dust fall, reduce the device that the good hole of waste gas effect separates dust, dust fall, subtracts waste gas.

The purpose of the utility model is realized like this:

the utility model discloses water smoke injection apparatus of dust removal, dust fall, subtract waste gas in hole, including high-order catch basin, be located the first person in charge, the second person in charge that the parallel hole room axis of hole department was arranged respectively in one end of hole both sides side wall department and high-order catch basin communicates with each other, many interval rings were arranged in parallel in the hole room to encircle the both ends above the waist and communicate with first person in charge, second person in charge respectively the hoop branch pipe that communicates with each other, each hoop branch pipe is equipped with gate valve and a plurality of vaporific shower nozzle, first person in charge, second person in charge keep away from on the hoop branch pipe one end respectively equipped with force (forcing) pump, ball valve, high-order catch basin and force (forcing); the ball valve, the main pipe, the branch pipe and the gate valve form a pipeline system; the mist head constitutes the spraying system.

The utility model discloses the during operation, the force (forcing) pump supplies water, is responsible for the water delivery, and circumferential branch pipe and vaporific shower nozzle sprinkle to separate dirt, dust fall and reduce waste gas, ensure pedestrian and worker physical and mental health.

The utility model discloses the hole room separates dirt, dust fall, subtracts waste gas water smoke injection apparatus can improve water smoke jetted distance and state through the big or small regulation water velocity of changing the force (forcing) pump, can start or close certain one section through opening and shutting of gate valve, can effectively keep apart the dust, reduce the raise dust, reduce waste gas, the assurance of very big degree pedestrian and worker's physical and mental health.

Drawings

FIG. 1 is a schematic plan view of the device of the present invention

Fig. 2 is a schematic view of the cross-section layout of the device of the present invention.

FIG. 3 is a schematic view showing the connection of the high-pressure collecting tank, the main pipe and the annular branch pipe.

The specific implementation mode is as follows:

referring to fig. 1 to 3, the water mist spraying device for dust separation, dust fall and waste gas reduction of the cavern of the embodiment comprises a high-level water collecting tank 1, a first main pipe 3 and a second main pipe 3-1 which are arranged in the cavern and are parallel to the axis of the cavern and are respectively arranged at one end of the side wall at two sides of the cavern and communicated with the high-level water collecting tank, and a plurality of annular branch pipes 4 which are arranged in the cavern in parallel at intervals and are respectively arranged at two ends above the arch of the cavern and communicated with the first main pipe and the second main pipe. Each annular branch pipe is provided with a gate valve 6 and a plurality of mist nozzles 7. The first main pipe and the second main pipe are respectively provided with a booster pump 2 and a ball valve 5. The high-level water collecting tank 1 is responsible for storing water, the pressure pump 2 is responsible for supplying water, and the high-level water collecting tank and the pressure pump form a pressure water supply system.

The first main pipe 3 and the second main pipe 3-1 are respectively made of phi 150 steel pipes; the annular branch pipe 4 is made of a phi 25 steel pipe; the ball valve 5 is a main switch pipe, so that another overhaul is facilitated; the gate valve 6 is a switch branch pipe, is convenient to overhaul, and forms a pipeline system. The mist nozzles 7 are arranged on the circumferential branch pipe at a certain interval (0.5 m) and are a spraying system.

When the device is used, the size of the high-level water collecting tank is determined according to the water supply amount, and the spray speed and distance of the water mist can be adjusted by adjusting the power of the pressure pump 2; the diameters of the first main pipe 3 and the second main pipe 3-1 are adjusted according to the number of the branch pipes arranged as required; the first and second main pipes can be opened or closed by using the ball valve 5; the annular branch pipe 4 can be opened or closed by using a gate valve 6; the spray state can be changed by changing the shape, size, etc. of the spray hole of the mist head 7.

Claims

1. The water mist spraying device is characterized by comprising a high-level water collecting tank, parallel cavern axes in the cavern are respectively arranged at one end of side walls on two sides of the cavern and a first main pipe communicated with the high-level water collecting tank, a second main pipe, a plurality of spaced annular parallel pipes are respectively arranged at two ends of the cavern above the arch waist and communicated with the first main pipe and the second main pipe, each annular branch pipe is provided with a gate valve and a plurality of vaporific spray heads, and the first main pipe and the second main pipe are respectively provided with a pressure pump and a ball valve at one end far away from the annular branch pipe.
