◆Why don’t we use polyurethane to make dust curtains?
Although polyurethane has good wear resistance, the molded product is relatively hard and is not suitable for use as dust curtains on guide troughs. Because winter is coming, the natural rubber material will not harden and crack.
The dust curtain has the following functions:
- Has blocking and filtering functions: Since the dust curtain is hung in the tunnel, the coal dust carried in the wind flow is blocked and filtered when passing through the dust curtain. It is captured by the dust curtain, thus reducing the concentration of coal dust in the air flow and purifying the air flow.
--With moistening and flushing functions: Since a purification spray device is installed in front of the dust curtain, the coal dust captured by the dust curtain is moistened by the water droplets of the purification spray and flushed to the tunnel floor to become never floating. of deposited coal dust.
Since the structure of the guide trough is the main factor that affects the dust removal effect, the factors include the length of the guide trough, the size of the flow cross-section at the entrance and exit, etc. Therefore, these main factors have become the main content of experimental research on improving the dust removal effect of the guide trough.
The dust removal effect of the guide trough is poor. Analysis of the main reason is that the dust-proof structure is not complete enough and the flow area at the outlet of the guide trough is too large (the outlet is close to open), so dust can fly freely without resistance. In response to existing problems, measures should be taken to install double or multi-layer soft dust curtains at the exit of the guide trough. After the implementation of the measures, the dust removal efficiency of the guide trough has been significantly improved. The guide trough can effectively control the free spread of dust and greatly reduce the quality of dust in the coal conveying trestle.
