(1) Except for grinding anthracite and semi-anthracite, when the coal milling system of the active lime factory operates under negative pressure, anti-riot valve should be installed. Device location: Active limestone production line Active limestone production line ① Mill inlet and outlet pipes. The cross section of the anti-riot valve is not less than 70% of the cross-sectional area of the pipeline; ② Two anti-riot valves should be installed on the top cover of the coarse powder separator; Four percent. (2) If the anti-riot valve of the dynamic separator is installed on the central short tube of the dynamic separator, its cross-sectional area shall not be less than 40% of the cross-sectional area of the short tube. At least two anti-riot valves should be installed on the top cover of the dynamic separator. The total area value shall be not less than 5% of the volume value of the dynamic separator. (3) The area value of the pulverized coal bin riot valve should be equivalent to 0.01 square meters per cubic meter of pulverized coal bin volume value, and should not be greater than 0.5 square meters. (4) On the inlet and outlet pipes of the dynamic separator and on the pipes in front of the exhaust fan or primary air blower, the cross-sectional area of the riot valve is generally not less than 70% of the cross-sectional area of the pipe.

(6) The anti-riot valve can be installed on the vertical pipeline above the air inlet of the mill, the dynamic separator and the pulverized coal silo. In the event of an explosion, the generated gas can be sent out through a vertical pipe. When it is difficult to arrange the pipeline, the inclined pipe may be allowed, but the inclined angle with the vertical direction shall not be greater than 50 degrees. The angle between the anti-riot valve installed outdoors and the horizontal plane shall not be less than 45 degrees.
