Dust-suppressing vehicles look like ordinary sprinklers, and they carry a large water tank behind them, but their essential functions are different. The dust suppression vehicle is a special vehicle that suppresses dust dust pollution by spraying a spraying liquid such as a dust suppression curing agent. Mainly applicable to railways, roads and other areas with high dust emission. The working principle of the dust suppression vehicle is to use the hydraulic system and the electronic control system to interact with each other. That is, the mobile spray equipment in the dosing station injects the spray liquid into the liquid storage tank. When the train passes, the photoelectric detection system starts to identify the vehicle and the vehicle passes through. After the signal is issued, the control personnel controls the transmission hydraulic system to dispose the liquid pipe and the vehicle compartment. When the liquid pump starts to spray, the liquid pump is started to spray, and the flow rate of the liquid pump is adjusted to meet the design spray standard. The structure of the dust suppression vehicle includes a swing arm spray device, a liquid storage tank, a self-propelled vehicle, and a control system. In the northern part of the country, the winter is cold and dry. Therefore, the tank body, spray nozzle, and pump body must be installed with insulation systems in order to work properly. On December 1, 2015, the multi-functional dust suppression vehicle began operation and dust suppression operations began in the Dachang Hui Autonomous County of Langfang, Hebei. On the same day, the Central Meteorological Observatory continuously issued the “Orange-and-Orange†warning, and heavy toads occurred in parts of Beijing, Tianjin, central and southern Hebei, northern Henan, and northern and western mountains. In order to ensure air quality, the multi-functional dust suppression vehicle started to move, through its own internal circulation operation, using its spraying system to launch water mist into the air, and rapidly reducing the particulate matter floating in the air to the ground to play a role in purifying the air. . Many citizens have reported that the multi-function dust suppression vehicle atomizes the water and sprays it through the “big barrel†to designated areas such as the street. The spray mist is a bit like a drizzler, but passers-by will not get wet. This special vehicle can effectively reduce the generation of dust and haze in the air. However, this vehicle is still in the commissioning stage, and the relevant departments of the municipal government will conduct functional monitoring of their operations. The effect of the initial use of air on the improvement of air quality is very obvious. It is estimated that it will be popularized soon afterwards. Â
An air cooler turbine is a device used in an air cooler that increases air flow and improves air cooling efficiency. A turbine is a rotating piece made up of a series of blades that turn as air passes through the turbine, creating a powerful flow of air. This airflow takes heat out of the air, making it cooler. The air cooler turbine is usually driven by a motor and can be adjusted as needed for speed and air volume. It is widely used in automobile, robot, electronic equipment and other fields.
Air cooler, referred to as "air cooler", also called fin fan, commonly used to replace the water cooled shell - tube Heat Exchanger cooling medium. It is a device for cooling or condensing the high temperature process fluid inside the tube by sweeping the finned tube with ambient air as the cooling medium. Air cooler is mainly used in petroleum, chemical, metallurgy and other air cooler supporting use, with large air volume, high efficiency, low vibration, low noise, easy maintenance and other advantages.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
