Embodiment 2

[0076] An embodiment of the present invention is a foam performance evaluation method for preventing and controlling industrial high-temperature dust, which is used in the experimental platform described in any one of Embodiment 1, comprising the steps of:

[0077] Arrange the experimental platform, start the air supply device and the heating device, and add dust into the dust control device;

[0078] After the uniformly mixed dusty airflow is evenly distributed in the transparent shell, the dust concentration monitoring system is started to monitor the initial dust concentration under the condition of no foam dust removal, and the external foam generating device is started. The foam includes gel foam, magnetized foam, water Base foam, heterogeneous foam, etc.;

[0079] By controlling the heating device, changing the temperature of the dust-laden airflow, respectively monitoring the change of the dust concentration at different temperatures, so as to measure the dust removal e...

Abstract

The invention discloses a foam prevention and control industrial dust method and an evaluation device, relates to the technical field of industrial dust prevention and control, and can realize comprehensive evaluation of dust removal performance of different foams at different temperatures. The device mainly comprises a transparent shell, a foam spraying device, an air supply device, a spiral outflow device, a digital display temperature sensor, a dust control device, a heating device, a high-speed camera, a thermal imager and a dust concentration monitoring device, wherein the foam spraying device is positioned in the transparent shell and is connected with the external foam generating device through a horizontal pipeline; dust concentration monitoring devices which are annularly and uniformly arranged are arranged above and below the foam spraying device; the spiral outflow device is located at the bottom of the transparent shell and outwards connected with a digital display temperature sensor, a dust control device, a heating device and an air supply device in sequence through a horizontal pipeline; the high-speed camera and the thermal imager device are arranged outside the transparent shell. The whole set of testing device is simple to operate, low in cost, good in controllability and comprehensive in testing parameters, and is particularly suitable for evaluating and researching the dust removal performance of different foams at different temperatures.

Description

technical field [0001] The foam prevention and control industrial dust method and evaluation device of the present invention relate to foam dust removal efficiency measurement and evaluation methods, and belong to the technical field of industrial dust prevention and control. Background technique [0002] Dust is one of the main pollution sources of urban air, which can induce pneumoconiosis and other occupational diseases. With the rapid development of my country's industrial economy in the past ten years, the problem of dust has become more and more prominent. According to the 2017 Bulletin on the State of the Ecological Environment in China issued by the Ministry of Environmental Protection, 72.8% of the 338 prefecture-level cities have air quality exceeding the standard, and 74.2% of the severe and above pollution is mainly caused by PM2.5. Dust can cause great harm to people's physical and mental health. According to statistics from the National Health Commission, there...
