Embodiment

[0019] Such as figure 1 As shown, the present invention provides an experimental device for testing the dust suppression effect of the foam sol, which mainly consists of three parts, namely the air supply part ( figure 1 shown in A), the sample test tube part ( figure 1 shown in B) and the test section ( figure 1 shown in C).

[0020] Air supply part: It consists of a stepless variable speed fan (GMS-900F) 1, a regulating valve 2 and a radially variable right-angle elbow 10. The continuously variable speed fan 1 is connected to the small end of the diameter-variable right-angle elbow 10 through the regulating valve 2, and the large mouth end of the diameter-variable right-angle elbow 10 is communicated with one end of the experimental tube 11 of the sample experimental tube part B through the quick connection valve 3.

[0021] Sample test tube part: including test tube 11 , quick connection valves 3 and 5 , slot 4 and sampling plate 13 . One end of the test tube 11 communi...

Abstract

An experimental device for testing an effect of foam collosol on inhibiting dust mainly comprises an air supply part, a sample experiment pipe part and a test part. The air supply part comprises a stepless speed change fan and a reducing right-angle elbow pipe. The sample experiment pipe part comprises an experiment pipe, a quick connection valve, a slot and a sampling plate. The test part comprises an anemograph, a test pipe, a DS-FC handheld intelligent dust tester and a dust concentration measuring port. The device can be used for quantitatively testing a critical wind speed value of the foam collosol for inhibiting the dust, so that a quantitative evaluation actual measurement instrument is provided for further researching and developing a new formula of the higher-efficiency foam collosol. The device can be further applied to quantitative test of the dust inhibition effect of a surface cohesive material for inhibiting bulk cargos. With the application of the device, a novel quantitative test and analysis method is provided for researching and developing technologies for inhibiting raised dust of coal piles and port bulk cargos, and the device has very wide application prospects in the research and development field.

Description

technical field [0001] The invention belongs to the technical field of coal mines, and relates to an experimental device for testing the effect of foam sol on dust suppression. The experimental device can be used to test the effective limit wind speed value of foam sol to suppress dust without raising dust. Background technique [0002] The potential safety hazards and occupational health problems caused by coal dust have become one of the key technical issues that need to be solved urgently in my country's coal mining, coal consumption, and coal transfer industries. Therefore, in order to effectively suppress coal dust, a new technology of foam sol for coal dust prevention is proposed. This technology has strong surface cohesiveness, which can firmly bond the surface of loose coal together, thereby preventing coal dust from raising dust due to external disturbances. [0003] So far, there is no test report on determining the effect of foam sol on coal dust suppression, an...
