Description
Technical Field
The invention belongs to the field of environmental protection. In particular to an injection fog gun device which is mainly used for reducing dust and haze.
Background
With the acceleration of the urbanization process in China, all industries in China also get rapid development, however, in all links of industrial chains such as the whole building industry, the coal industry, the urban construction, the electric power industry and the like, a lot of construction and use processes have great influence on urban air pollution, if the weather is dry and slightly windy, dust easily flies, and solid particles are generated to the environment, so that great influence is caused.
Aiming at the continuous and random dust and haze, a plurality of fog guns appear, and the fog guns are mainly used in places where dust pollution needs to be treated, such as cities, construction sites, equipment use sites and the like; liquid fog dust fall, the particle concentration in the decomposition desalination air, can effectively decompose pollution particulate matter, dust etc. in the air can be carried out in haze weather, effectively alleviate the haze. The device can also be used in areas needing dust fall, such as coal yards, coal storage bins or totally enclosed coal storage places, coal logistics parks, coal centralized transportation stations, open-air coal mining and the like.
However, the range of the common fog gun is 30-100m, and some fog guns need larger range, and need larger fan and booster pump to provide much power, so that the energy consumption is high, and further considerable noise is accompanied.
The injection fog gun device has the characteristics of long injection distance, good atomization effect, low noise value and the like, and meets the requirements of use places.
Disclosure of Invention
The invention provides an injection fog gun device which is long in spraying distance, good in atomization effect and low in noise value.
An injection fog gun device is characterized by comprising a first guide cylinder, an anti-blocking adjustable nozzle bracket, an anti-blocking adjustable nozzle, an atomizing nozzle, a water inlet pipe, a fan and a second guide cylinder; the fan is arranged between the first guide cylinder and the second guide cylinder, the second guide cylinder is connected with the air inlet of the fan, and the first guide cylinder is connected with the air outlet of the fan; a circle of atomizing nozzles are arranged at the outlet of the first guide cylinder; the center position of the middle section of the first guide cylinder is provided with an anti-blocking adjustable nozzle through an anti-blocking adjustable nozzle bracket; the anti-blocking adjustable nozzle and the atomizing nozzle are connected with the booster pump unit through a water inlet pipe.
The second guide cylinder is in a horn opening shape, air enters from a large opening, air exits from a small opening, the air inlet of the fog gun is arranged, the area of the air inlet is increased, and air can smoothly enter the fog gun.
The first guide cylinder is a conical cylinder, air enters from a large opening, air exits from a small opening, and is arranged at an air outlet of the fog gun, so that the diameter of the guide cylinder is reduced, and the air flow rate is increased.
The anti-clogging adjustable nozzle is the nozzle in a novel fog gun device. The single-beam atomizing nozzle sprays more concentrated water mist, and the water mist is small in amount, large in pressure and high in speed. The support is fixed at the axis position of the middle section of the first guide cylinder, and the anti-blocking adjustable nozzle can also adjust the water quantity.
The atomizing nozzle is made of stainless steel or brass and is arranged outside the outlet of the first guide cylinder, the circle of the atomizing nozzle is uniformly arranged, the amount of water mist is large, but the speed is relatively low, and the atomizing nozzle is a main atomizing device of a fog gun.
The dust and haze removing system is arranged at a fixed high place or on a vehicle, and is combined with a frequency converter, a power device, a booster pump unit, an electric control cabinet and a rotary mounting bracket to form a set of fixed or movable multifunctional dust and haze removing system.
The invention adopts a single-beam nozzle to emit higher-speed water mist which is arranged at the axis position in a mist gun; the atomizing nozzles on the periphery of the outlet of the first guide cylinder form a ring shape, jet out water mist with relatively low speed and are arranged at the outlet of the fog gun. The small amount of water mist ejected from the pressurized single-beam nozzle has high pressure and flow velocity, is working fluid and is ejected from the nozzle at high speed. And (3) under the turbulent dispersion action of jet flow and the direction of the fog gun opening and the fog gun range, the water mist with large ejection quantity and lower relative pressure around the entrainment periphery is ejected by the annular multi-nozzle. The sucked water mist with lower pressure and larger volume is used as the ejection fluid. The working fluid and the injection fluid are mixed at the fog gun port under the action of the fan, equivalently, the working fluid and the injection fluid enter a mixing space for momentum exchange, the velocity distribution is gradually uniform in the process, and the pressure is often increased in the process. Then, the mixed water mist enters the diffusion space after being away from the mist gun opening for a certain distance, and the pressure is increased due to the reduction of the flow speed. The pressure of the mixed water mist is higher than the average value of the pressures of the two water mist, so that the original pressurized water mist range is farther. The main characteristic of the injection fog gun is that the pressure of the injection fog is increased without directly consuming mechanical energy. The injection fog gun can directly utilize various pressure energy sources as working power, does not need to increase auxiliary equipment, and can obtain good comprehensive benefits.
