Embodiment 1
[0033] A method of preventing soot spraying on an air release valve of a double chamber kiln comprising the use of a Figure 6 , Figure 7 , Figure 8 The specific method for preventing the soot spraying device of the air release valve of the double-chamber kiln shown is as follows:
[0034] A. When the system cuts off the gas transported to the kiln, that is, before entering the burnout time, the system controls to open the electric control valve 14, and the gas in the kiln is transported to the dust collector through the exhaust pipe 13 and the waste gas pipe 3, and the pressure in the kiln enters Reduce to below 10kpa before the reversing period; when the burnout time is short and the pressure in the kiln drops below the set value, further set to prolong the burnout time to achieve a sufficient reduction in the gas pressure in the kiln; then open the combustion air release valve 11, Adjust the opening speed of the combustion air release valve 11 to 8 seconds to realize th...

[0040] A method of preventing soot spraying on an air release valve of a double chamber kiln comprising the use of a Figure 6 , Figure 7 , Figure 8 The specific method for preventing the soot spraying device of the air release valve of the double-chamber kiln shown is as follows:
[0041] A. When the system cuts off the gas transported to the kiln, that is, before entering the burnout time, the system controls to open the electric control valve 14, and the gas in the kiln is transported to the dust collector through the exhaust pipe 13 and the waste gas pipe 3, and the pressure in the kiln enters Reduce to below 10kpa before the reversing period; when the burnout time is short and the pressure in the kiln drops below the set value, further set to prolong the burnout time to achieve a sufficient reduction in the gas pressure in the kiln; then open the combustion air release valve 11, Adjust the opening speed of the combustion-supporting air release valve 11 to 10 seconds t...
