The invention discloses a method and device for determining the optimal distance of nozzles in a wet string grid air purification device. The method comprises the steps that S1, the average value of the dust particle size range is calculated; s2, selecting an atomization average particle size and a nozzle corresponding to the atomization average particle size according to the average value of the dust particle size range; s3, parameters of the wet string grid air purification device are determined, wherein the parameters comprise the optimal water supply pressure and the optimal filtering air speed; s4, generating an on-way particle size distribution diagram of the atomized test droplet cluster; and S5, taking the measurement point distance corresponding to the intermediate value of the optimal atomization particle size distribution interval section as the optimal mounting distance of the nozzle. According to the method, the optimal mounting distance of the nozzles in the wet string grid air purification device is determined through testing, so that liquid drops atomized by the nozzles are mixed with dust more sufficiently, the dust removal efficiency is improved, and water resources are saved. The invention further discloses a wet string grid air purification device, the mounting distance of the nozzles is determined through the method, and therefore the wet string grid air purification device has the optimal dust removal efficiency.
Description
【Technical field】 [0001] The invention relates to the technical field of environmental protection equipment, in particular to a method and a device for determining the optimum distance of nozzles in a wet string grid air purification device. 【Background technique】 [0002] With the advancement of national science and technology and the continuous development of high-speed rail and subway, my country has become a country with the most complex and diverse tunnels in the world. In the process of tunneling, blasting construction causes serious dust and harmful gas pollution, which endangers the health of workers and the surrounding environment. Therefore, in order to form a good circulation of fresh air, ventilation and dust removal methods must be adopted, and the supporting technology is the wet string grid air purification device. [0003] The wet string grid air purification device is a dust removal device that achieves the purpose of dust treatment through spray dust reduc...
