Description

Emission-control equipment
Technical field
The present invention relates to a kind of emission-control equipment.
Background technique
Underground coal mine vehicle is cooled by waste gas treatment tank the waste gas that motor is discharged and washs, the part harmful gas removed charcoal cigarette and dissolve in waste gas, and extinguishes the flame in waste gas, to ensure exhaust, safety through Explosion-resistant pale.China's Authorization Notice No. is the waste gas treatment tank that CN203978574U utility model patent specification discloses a kind of underground coal mine vehicle, comprise large water tank, little water tank, the water of little water tank enters large water tank by syphon tube, be provided with ball float water level control mechanism in little water tank, ball float water level control mechanism is connected with water-adding pipe.Water-adding pipe is generally connected with the water supply tank on vehicle, the setting height(from bottom) of water supply tank on vehicle is greater than the setting height(from bottom) of waste gas treatment tank, water level in waste gas treatment tank makes the water route of water supply tank and waste gas treatment tank connect lower than during needed height by ball float water level control mechanism, water in water supply tank relies on the effect of gravity to enter in the little water tank of waste gas treatment tank, and the clean water in little water tank is filled in large water tank by syphon tube according to the principle of siphonage.When anhydrous in water supply tank, even if large water tank water level is lower, do not have water can fill in little water tank, cause large water tank water level not up to standard, waste gas can not get process.The waste gas that underground coal mine is not treated be do not allow discharge, above-mentioned model utility arranges level sensor in large water tank for this reason, for feeding back the water yield of large water tank, but make the structure of waste gas treatment tank loaded down with trivial details, and the sewage in large water tank can make the ball float of level sensor not easily move up and down along measuring guide, measurement signal is inaccurate.
Summary of the invention
The object of the invention is to propose a kind ofly can ensure that not treated waste gas does not discharge and the emission-control equipment that is simplified of structure.
For achieving the above object, the present invention takes following technological scheme: the present invention includes waste gas treatment tank, water-adding pipe, water supply tank, waste gas treatment tank 1 comprises large water tank and is in the little water tank in large water tank, little water tank is connected by syphon tube with between large water tank, in addition, also comprise solenoid valve for water, monitoring host computer and flame-out cylinder solenoid valve, monitoring host computer has electric controller, above-mentioned solenoid valve for water is connected in water-adding pipe, level sensor is provided with in little water tank, the signaling line of level sensor, the flame-out guide line of cylinder solenoid valve is all connected with the electric controller in monitoring host computer with the guide line of solenoid valve for water, described water-adding pipe one end is connected with water supply tank, the other end leads to little water tank through the tank wall of large water tank, connect when electric controller controls solenoid valve for water, water supply tank is to little water tank moisturizing, the timing simultaneously of timer in monitoring host computer, timer arrives the time of setting, electric controller does not receive the signal of level sensor, namely electric controller controls flame-out cylinder solenoid valve and connects, flame-out cylinder quits work, engine misses.
Described level sensor comprises sound-pipe and to be enclosed within sound-pipe and can the ball float of movement on sound-pipe.
The present invention has following good effect: (1) the present invention takes in little water tank, arrange level sensor and replaces ball float water level control mechanism, cancel the level sensor in large water tank, the structure of emission-control equipment is simplified, owing to being clean water in little water tank, ball float easily moves up and down along measuring guide, makes measurement signal accurate.(2) the present invention utilizes the timer in monitoring host computer, when moisturizing, arrive set time, electric controller does not receive the signal of level sensor, namely electric controller controls flame-out cylinder solenoid valve and connects, and flame-out cylinder quits work, engine misses, motor does not have waste gas to produce, and ensure that not treated waste gas does not discharge.
Accompanying drawing explanation
Fig. 1 is emission-control equipment fundamental diagram.
Embodiment
Embodiment 1
See Fig. 1, a kind of emission-control equipment, comprise waste gas treatment tank 1, water-adding pipe 2, solenoid valve for water 3, monitoring host computer 4, flame-out cylinder solenoid valve 5 and water supply tank 6.Waste gas treatment tank 1 comprises large water tank 1-1, little water tank 1-2, little water tank 1-2 is in large water tank 1-1, little water tank 1-2 is connected by syphon tube 1-3 with between large water tank 1-1, during the water level of the water level in little water tank 1-2 higher than large water tank 1-1, water in little water tank 1-2 fills in large water tank 1-1 by syphon tube 1-3, the end face of large water tank 1-1 fixes a level sensor 1-5, the sound-pipe 1-5-1 of level sensor 1-5 and ball float 1-5-2 inserts in little water tank 1-2, and ball float 1-5-2 slides up and down along sound-pipe 1-5-1 according to the water level in little water tank 1-2.
Described little water tank 1-2 is in the side of large water tank, the outer side surface of this side box wall of little water tank 1-2 is affixed to the inner side surface of the corresponding side box wall of large water tank 1-1, the tank wall bottom that large water tank 1-1 and little water tank 1-2 is affixed has hole, the tank wall of the through little water tank 1-2 in hole, be fixed with joint 1-4 in hole, one end of water-adding pipe 2 is connected with water supply tank 6, and water-adding pipe 2 the other end is connected with joint 1-4, the tank wall making water-adding pipe pass large water tank 1-1 leads to little water tank 1-2, connects described solenoid valve for water 3 in water-adding pipe 2.
