When the sand does not hit When the upper row of baffles 44 hits the lower row of baffles 44, the sand will fall on the bottom of the collecting box 31 near the discharge port. When the sand does not hit the two rows of baffles 44, the sand will fall on the bottom of the collecting box 31 away from the discharge port, so as to achieve full coverage of the bottom of the collecting box 31 and extinguish the molten material. Carbon monoxide and carbon dioxide will be produced during the combustion of the optical cable. Carbon monoxide is toxic and the post-combustion gas needs to be disposed of in advance, otherwise it will cause harm to the health of the staff. When the combustion test is over, the exhaust fan 45 is started. The exhaust fan 45 draws air from the outer shell 1 through the suction pipe 46 and passes the air into the box body 48 through the connecting pipe 47. Carbon monoxide will react with the copper chloride solution. After the gas enters the copper chloride solution,The gas moves along the blocking plate 50 and the blocking block 51 in the form of bubbles, which increases the contact time between the gas and the solution, and the treated gas is discharged from the gas outlet pipe 49.
