Embodiment Construction

[0016] In order to facilitate the understanding of those skilled in the art, the following in conjunction with the attached figure 1 , the structural principle of the present invention is described in further detail:

[0017] A device for testing and evaluating the dust suppression rate of a dust suppressant. The axial flow fan 1 is a frequency modulation fan, and its own speed can be adjusted through the frequency regulator. Humidity regulator 6 regulates the temperature and humidity of the experimental cabin. When testing under high-speed wind, such as wind speeds above grade 8, experimental dust can be manually placed at the front end of the high-speed wind section 2 of the experimental cabin, and the high-speed wind section 2 of the experimental cabin The set test port is used to test the wind speed, total dust, and particle size distribution of a certain wind speed blowing through the coal pile with the smoke sampler 7 and the electric low-pressure impactor 8 respectively...

Abstract

The invention discloses an unorganized-dust dust suppressant dust restraining rate testing and evaluating device and a method. The unorganized-dust dust suppressant dust restraining rate testing and evaluating device mainly comprises an axial flow fan, an experiment cabin, and a measuring amount adjusting and controlling device; the measuring amount adjusting and controlling device is composed of a temperature and humidity regulator, a smoke dust sampling device, and an electrical low pressure impactor; the axial flow fan is connected with an experiment cabin high speed wind section via flexible connection; the axial flow fan is connected with the temperature and humidity regulator; the experiment cabin is divided into the experiment cabin high speed wind section, an experiment cabin wind direction adjusting section, an experiment cabin low speed section, and an experiment cabin air exhaust section along wind direction tendency; the top of the experiment cabin high speed wind section is provided with testing ports; a wind direction adjusting device is arranged between the experiment cabin wind direction adjusting section and the experiment cabin low speed section; the top of the experiment cabin low speed section is provided with a twin-fluid atomization nozzle and a material falling port, the bottom is provided with a wastewater discharge hole, and the side surface is provided with testing ports; and the smoke dust sampling device and the electrical low pressure impactor are connected with the testing ports. The unorganized-dust dust suppressant dust restraining rate testing and evaluating device is convenient and accurate for testing, is reliable, and is capable of stimulating environmental parameters accurately.

Description

1. Technical field [0001] The invention belongs to the field of environmental technology, and specifically refers to a device for testing and evaluating the dust suppression rate of a fugitive dust suppressant. 2. Background technology [0002] Unorganized dust discharge usually refers to dust discharge without fixed discharge facilities or below a certain height, which widely exists in various links such as bulk material production, processing, transportation, loading and unloading, not only in mines, but also in construction, quarries, storage yards, ports, etc. , thermal power plants, steel plants, cement plants, waste recycling and other places may occur. Taking thermal power plants as an example, fuel coal is easy to generate secondary dust during transportation, loading and unloading, and storage. Stone, cement, sand, etc. required for building construction will also produce a large amount of particles with a particle size less than 2.5 μm during the preparation proces...
