Abstract
The utility model relates to a high pressure water mist generator. Each year, gas explosion accidents incessantly happen, causing a large loss of life and property. According to the utility model, aninlet of a high pressure water pump is communicated with a water storage tank, an outlet of the high pressure water pump is communicated with an inlet of an overflow valve, an outlet of the overflow valve is communicated with a rotary spray nozzle through a hose pipe, a flow meter and a water mist control valve are arranged on the hose pipe, and an overflow opening of the overflow valve is communicated with the water storage tank. An electric motor is in matching connection with the high pressure water pump, a methane density detecting instrument is in signal connection with a signal input terminal of a controller, and a signal output terminal of the controller is in signal connection with an electric motor to control the turn-on and turn-off state of the electric motor. The high pressurewater mist generator can timely detect gas leakage in mines and is automatically opened in restricted time to decrease the density of the methane gas before methane density reaches explosion degree.
Description
Technical field
The utility model belongs to the safety production technique field, relates to the methane explosion prevention technology that ensures Safety of Coal Mine Production, is specifically related to a kind of high-pressure water mist generator.
Background technology
China is the big country of world's coal production and consumption, and coal is in one section very long from now on main energy sources that will be still China period.Coal mine gas is a kind of fuel gas based on methane, and the explosion limit of methane in air is 5.3～14.0%, meets naked light and will blast in the explosion limit scope.Can produce a large amount of heats during gas explosion, and form flame, temperature can reach 1850～2650 ℃, causes personnel to be burnt, and also can cause coal-dust explosion and mine fire, also can produce a large amount of toxic and harmfuls simultaneously, and airborne oxygen content reduces greatly.
The annual gas explosion accident in the whole nation constantly takes place, and has caused the heavy losses of lives and properties.If it is strengthen the real-time concentration of monitoring and in time reducing mine leakage gas of gas in the mine, significant to generation of minimizing accident and life and property loss so.
Summary of the invention
The purpose of this utility model is to provide a kind of and absorbs to reduce the high-pressure water mist generator of methane concentration by super-pressure water smoke.This high-pressure water mist generator can detect the concentration of methane in the mine in real time, opens when methane reaches the dangerous concentrations of setting, reduces methane concentration by the thin water smoke of super-pressure that sprays, to ensure the safety in production in colliery.
High-pressure water mist generator of the present utility model comprises water supply installation, water storage box, methane concentration detector, controller, overflow valve, high-pressure hydraulic pump, rotary nozzle.
The delivery port of water supply installation is arranged on the top of water storage box, the position of corresponding water supply installation delivery port is provided with screen pack in the water storage box, the outlet pipe of water supply installation is provided with water inlet switch, be provided with float in the water storage box, float and water inlet switch are connected, the unlatching and the closure of control water supply installation delivery port.Water supply installation is water tank or tap water pipe line.
The bottom of the import of high-pressure hydraulic pump and water storage box sidewall is by the water pump pipeline connection, the water pump pipeline is provided with the pump capacity meter, the water under high pressure delivery side of pump is communicated with the import of overflow valve, the outlet and the rotary nozzle of overflow valve pass through soft pipe connection, flexible pipe is provided with flow meter and water smoke control valve, and the overfall of overflow valve is communicated with water storage box.
The clutch end of motor and the central axis of high-pressure hydraulic pump are connected, for high-pressure hydraulic pump provides power.The methane concentration detector is connected with the signal input part signal of controller, and the signal output part of controller is connected with the motor signal, the switch of control motor.
High-pressure water mist generator of the present utility model can in time detect the gas leakage in the mine, and when not reaching lower explosive limit, opens methane concentration high-pressure water mist generator automatically, reduce the concentration of methane gas, alarm gives the alarm simultaneously, does stringent effort for the mine personnel grace time.Unexpected blast with regard to having avoided causing owing to the unexpected naked light that causes in the explosion limit scope when methane concentration causes personnel's heavy casualties like this.The utility model efficiently solves the potential problem that causes coal mine gas from explosion, and is significant for the safety in production in the mine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of high-pressure water mist generator comprises water supply installation 1, water storage box 14, methane concentration detector 6, controller 5, overflow valve 11, high-pressure hydraulic pump 12, rotary nozzle 8.
The delivery port of water supply installation 1 is arranged on the top of water storage box 14, the position of corresponding water supply installation 1 delivery port is provided with screen pack 3 in the water storage box 14, the outlet pipe of water supply installation 1 is provided with water inlet switch 2, be provided with float 15 in the water storage box 14, float 15 is connected with water inlet switch 2, the unlatching and the closure of control water supply installation 1 delivery port.
The bottom of the import of high-pressure hydraulic pump 12 and water storage box 14 sidewalls is by the water pump pipeline connection, the water pump pipeline is provided with pump capacity meter 13, the outlet of high-pressure hydraulic pump 12 is communicated with the import of overflow valve 11, the outlet of overflow valve 11 is communicated with by flexible pipe 9 with rotary nozzle 8, flexible pipe 9 is provided with flow meter 10 and water smoke control valve 7, and the overfall of overflow valve 11 is communicated with water storage box 14.
The central axis of the clutch end of motor 4 and high-pressure hydraulic pump 12 is connected, for high-pressure hydraulic pump 12 provides power.Methane concentration detector 6 is connected with the signal input part signal of controller 5, and the signal output part of controller 5 is connected with motor 4 signals, the switch of control motor 4.
The control procedure of this high-pressure water mist generator is as follows: the concentration that is detected methane in the mine by the methane concentration detector in real time, and send signal to controller by the methane concentration detector, when the detected methane concentration value of methane concentration detector reaches setting value, controller sends signal instruction to motor, makes the work of driven by motor high-pressure hydraulic pump.High-pressure hydraulic pump extracts the water in the water storage box, make water under high pressure through the overflow valve pressure regulation after flexible pipe arrives rotary nozzle again, and form thin water smoke by nozzle ejection, water smoke can be controlled by the water smoke control valve.Water inlet by switch control water supply installation replenishes the water in the water storage box.Screen pack between water supply installation water inlet and water storage box will regularly clean, to guarantee its cleaning.
