Embodiment 1

[0058] Such as figure 1 and figure 2 As shown, the dust suppression agent of the present invention, the dust removal effect test device of the dustproof agent include a data acquisition and processing device, a simulated roadway device 27 for simulating the actual coal mine roadway, a dust generating device 1 for transporting dust in the simulated roadway device 27, and a simulation The dust-proof agent spraying device 9 and the dedusting device 22 for dust removal in the roadway device 27, the data collection and processing device includes a microcontroller 8 and a communication module 11 connected with the microcontroller 8 and bidirectionally communicating with a computer 12, The input terminal of the microcontroller 8 is connected with a dust sensor 6 for detecting the dust concentration in the simulated roadway device 27, and the output terminal of the microcontroller 8 is connected with a display 21;

[0059] The dust generating device 1 includes a crusher 4 for crushi...

Embodiment 2

[0072] Include the following steps in this embodiment:

[0073] Step 1. Prepare the dust not soaked in the dust suppressant solution: use the dust generating device 1 to prepare the dust not soaked in the dust suppressant solution, the process is as follows:

[0074] Using the crusher 4 to crush the material to be crushed to obtain a first powder, then screen the first powder, and put the screened first powder into a constant temperature box for constant temperature drying treatment to obtain a first dust sample, Then weigh two parts of the first dust of the same quality from the first dust sample and put them into two dust boxes 3 respectively; The two dust boxes 3 of the first dust are respectively called the first dust box and the second dust box;

[0075] Step 2. Prepare the dust soaked in the dust suppressant solution: use the dust generating device 1 to prepare the dust soaked in the dust suppressant solution, the process is as follows:

[0076] First of all, put the m...

Embodiment 3

[0106] The difference between this embodiment and embodiment 2 is: the temperature of the constant temperature drying treatment in step 1 and step 2 is 50°C, and the time of constant temperature drying treatment is 30h; The residual dust of the dust is removed for 120min, the concentration of the dust suppressant mixed solution is 5%, the concentration of the dust suppressant mixed solution is 25%, the flow rate of the infusion tube 16 is 5L / h, and the pressure of the infusion tube 16 is 0.5 MPa.

[0107] In this embodiment, the remaining steps and process parameters are the same as those in Embodiment 2.

[0108] In this embodiment, the dust removal efficiency of the dust suppressant is 92.3%, the dust removal efficiency of the dust remover is 93.7%, and the dust removal efficiency of the dust suppressant and the dust remover is 98.9%.

The testing method comprises the following steps: 1, preparing dust which is not soaked in a dust suppressant solution; 2, preparing dust which is soaked in the dust suppressant solution; 3, measuring the air dust concentration in a simulated roadway; 4, conveying the dust which is not soaked in the dust suppressant solution and measuring the dust concentration in the simulated roadway; 5, starting the dust preventive spraying device while conveying the dust which is not soaked in the dust suppressant solution, and measuring the dust concentration in the simulated roadway; 6, conveying the dust which is soaked in the dust suppressant solution and measuring the dust concentration in the simulated roadway; 7, starting the dust preventive spraying device while conveying the dust which is soaked in the dust suppressant solution, and measuring the dust concentration in the simulated roadway; 8, processing data and obtaining the dust removing efficiency. The testing device and the testing method, disclosed by the invention, are capable of testing the dust removing effect of the dust suppressant and the dust preventive.

Description

technical field [0001] The invention belongs to the technical field of dust prevention and control, and in particular relates to a dust-removing effect test device and a test method of a dust suppressant and a dust-proof agent. Background technique [0002] In recent years, with economic development and technological improvement, my country's coal mining technology has also been improved accordingly, but in the process of coal mining, dust still exists, and dust is still one of the five major disasters in mines, which not only threatens the health of workers Health, but also affect the safety and green production of mines. Coal mine dust is a variety of rock ore particles produced in various links of coal mining, accumulation, transportation, processing and utilization, mainly rock dust and coal dust. With the continuous development of the coal industry, the degree of mechanization of operations and the intensity of coal mining continue to increase, the amount of dust in roc...
