Description
技术领域 technical field
本发明属于环保设备技术领域，具体涉及一种气液混合喷雾装置。 The invention belongs to the technical field of environmental protection equipment, and in particular relates to a gas-liquid mixing and spraying device.
背景技术 Background technique
颗粒物污染是影响我国城市空气质量的首要因素,我国北方大部分城市气候比较干燥，多风，较多的大气扬尘和车辆轮胎磨损及车辆携带物和尾气颗粒等洒落造成城市道路容易积尘。为了消除城市道路扬尘，加大空气湿度，降低地面温度，改善空气质量，现有的做法是清扫和洒水降尘。洒水车通常喷洒的是稍加压力的水柱，能够辐射一定的路面，喷洒过后路面会积聚一定的水面，在水分完全蒸发之前保持路面细尘不被自然风和车辆尾流扬起，达到一定降尘的目的。北方城市气候干燥，洒一次水所起的降尘的作用甚至超不过半小时，作用时间太短；如果持续洒水，水消耗量极大，而这些城市大多缺水，造成经济一定的负担；且长期洒水容易使路面发生浸泡塌陷，高温的路面遇水会开裂，缩短路面的寿命。 Particle pollution is the primary factor affecting the air quality of cities in my country. The climate in most cities in northern my country is relatively dry and windy. More atmospheric dust and vehicle tire wear and vehicle carry-on and exhaust particles cause urban roads to accumulate dust easily. In order to eliminate dust from urban roads, increase air humidity, reduce ground temperature, and improve air quality, the existing practice is to sweep and sprinkle water to reduce dust. Sprinklers usually spray a slightly pressurized water column, which can radiate a certain amount of road surface. After spraying, a certain amount of water will accumulate on the road surface. Before the water is completely evaporated, the fine dust on the road surface will not be raised by the natural wind and the wake of the vehicle to achieve a certain degree of dust reduction. the goal of. The climate in the northern cities is dry, and the dust reduction effect of one sprinkling of water does not exceed half an hour, which is too short; if the water is continuously sprinkled, the water consumption will be huge, and most of these cities are short of water, causing a certain burden on the economy; and long-term Sprinkling water will easily cause the pavement to soak and collapse, and the high-temperature pavement will crack when it encounters water, shortening the life of the pavement.
发明内容 Contents of the invention
本发明的目的是提供一种气液混合喷雾装置，以解决现有的洒水降尘设备喷洒水柱，耗水量大，降尘作用时间短，容易给路面带来损害的问题。 The object of the present invention is to provide a gas-liquid mixing and spraying device to solve the problems of large water consumption, short dust-reducing action time and easy damage to the road surface caused by the existing sprinkler and dust-reducing equipment spraying water column.
为解决上述技术问题，本发明所采取的技术方案为： In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
一种气液混合喷雾装置，它包括安装在支架上的动力装置、水箱、数个喷头，喷头的底端安装在中空的喷杆上，所述水箱通过进水管与柱塞泵的进水口相连接，柱塞泵的出水口通过高压水管与水气混合装置相连接，水气混合装置还与高压空气储罐相连接，高压空气储罐的进气口与空气压缩装置相连接，水气混合装置与喷杆相连通；空气压缩装置、柱塞泵分别通过皮带轮与动力装置相连接。 A gas-liquid mixed spraying device, which includes a power device installed on a bracket, a water tank, and several nozzles, the bottom of which is installed on a hollow spray rod, and the water tank is connected to the water inlet of a plunger pump through a water inlet pipe. Connection, the outlet of the plunger pump is connected to the water-air mixing device through the high-pressure water pipe, the water-air mixing device is also connected to the high-pressure air storage tank, the air inlet of the high-pressure air storage tank is connected to the air compression device, and the water-air mixing device The device is connected with the spray rod; the air compression device and the plunger pump are respectively connected with the power device through the belt pulley.
优选的，所述喷头为多孔喷头，孔的直径为120-150μm。 Preferably, the nozzle is a porous nozzle, and the diameter of the holes is 120-150 μm.
优选的，所述喷头呈倒锥形安装在喷杆上。 Preferably, the spray head is installed on the spray rod in an inverted cone shape.
优选的，所述水气混合装置上设有阀门。 Preferably, the water-air mixing device is provided with a valve.
优选的，所述柱塞泵上设有进水量调节阀、回流阀、调压阀，柱塞泵的最大压力为35MPa,最高转速为700rpm。 Preferably, the plunger pump is provided with a water intake regulating valve, a return valve, and a pressure regulating valve. The maximum pressure of the plunger pump is 35MPa, and the maximum speed is 700rpm.
优选的，所述动力装置为柴油机或汽油机或电动机，动力装置上设有控制器。 Preferably, the power device is a diesel engine or a gasoline engine or an electric motor, and the power device is provided with a controller.
本发明在使用时，动力装置启动后，柱塞泵将水箱中的液体吸入，通过柱塞泵对液体加压后进入水气混合装置；同时动力装置带动空气压缩装置工作，给高压空气储罐中输入高压空气，高压空气储罐中的高压空气进入水气混合装置中；在水气混合装置内高压水和高压空气充分混合形成水雾进入喷杆中，经过喷头喷洒向空中。经过阀门的调节，喷头喷射出的每粒水珠的直径在120-150微米，喷头的喷洒量为25-35L/min，喷洒射程为1-2M。本装置就像空中喷射出由细微的水粒组成雾气，可以漂浮在空气中，达到降尘、加湿、净化空气的效果。 When the present invention is in use, after the power unit is started, the plunger pump sucks the liquid in the water tank, pressurizes the liquid through the plunger pump, and then enters the water-air mixing device; at the same time, the power unit drives the air compression device to work to supply high-pressure air to the storage tank. The high-pressure air is input into the high-pressure air tank, and the high-pressure air in the high-pressure air storage tank enters the water-air mixing device; the high-pressure water and high-pressure air are fully mixed in the water-air mixing device to form water mist, which enters the spray bar and sprays into the air through the nozzle.

This device is like spraying mist composed of fine water particles in the air, which can float in the air to achieve the effects of dust reduction, humidification and air purification.
柱塞泵工作时，不能超过最大压力30MPa和最高转速650rpm。压力过大则加压后的水呈极小的雾状颗粒，重力小于微尘，达不到降尘的目的；压力小加压后的水形状不变，压力极小时加压后的水呈滴灌状，均会在路面积聚，对路面造成影响。 When the plunger pump is working, it cannot exceed the maximum pressure of 30MPa and the maximum speed of 650rpm. If the pressure is too high, the pressurized water will be in the form of very small mist particles, and the gravity will be smaller than that of fine dust, which will not achieve the purpose of dust reduction; if the pressure is small, the shape of the pressurized water will not change, and if the pressure is extremely small, the pressurized water will be drip irrigation will accumulate on the road surface and affect the road surface.
喷头的喷射形式、大小、形状，均由柱塞泵上的调压阀控制。 The injection form, size and shape of the nozzle are all controlled by the pressure regulating valve on the plunger pump.
