Self-purification method for machine-made charcoal kiln smoke collecting pipe and kiln smoke collecting system for self-purification method

Abstract

The invention relates to a self-purification method for a machine-made charcoal kiln smoke collecting pipe and a kiln smoke collecting system for the self-purification method. The method comprises the steps that bamboo and wood vinegar liquor in a liquor collecting pool flows back to the portion near the air inlet end of the kiln smoke collecting pipe through a circulating liquor supply pipeline, and the bamboo and wood vinegar liquor is used for spraying and purifying kiln smoke newly entering the kiln smoke collecting pipe; the kiln smoke collecting pipe has a certain degree of inclination, and the liquor in the kiln smoke collecting pipe is guided out from the low end and flows to the liquor collecting pool; and the smoke in the kiln smoke collecting pipe is guided out from the high end and flows to a water-gas separation device. According to the self-purification method for the machine-made charcoal kiln smoke collecting pipe and the kiln smoke collecting system, the bamboo and wood vinegar liquor flows back to the air inlet end of the kiln smoke collecting pipe through the circulating liquor supply pipeline; on the one hand, kiln smoke purification is facilitated, vaporific gas in the kiln smoke is condensed quickly, the smoke is set quickly, and the vaporific gas and the smoke flow to the liquor collecting pool along with the bamboo and wood vinegar liquor; and on the other hand, due to the fact that the bamboo and wood vinegar liquor flows in the kiln smoke collecting pipe in a circulating manner, the flushing function on the inner wall of the kiln smoke collecting pipe is achieved, and thus the kiln smoke collecting pipe can be prevented from being blocked, and the ventilatory capacity of the pipe and the pipe gas delivery safety are increased.

Description

technical field [0001] The invention relates to a self-purification method of a machine-made charcoal kiln smoke collection pipe and a kiln smoke collection system, belonging to the treatment technology of machine-made charcoal kiln smoke. Background technique [0002] When machine-made charcoal is burned in a charcoal kiln to make charcoal rods, certain kiln smoke will be produced, and the direct discharge of kiln smoke into the air will cause air pollution. According to environmental protection requirements, kiln smoke needs to be treated. For this reason, those skilled in the art usually transport the kiln smoke from the charcoal kiln to the drying furnace through a negative pressure collection pipeline for combustion. Because the kiln smoke contains wood gas, wood tar, wood vinegar or bamboo vinegar, etc., and wood tar, wood vinegar or bamboo vinegar are easy to adhere to the inner wall of the negative pressure collection pipe, it is easy to cause the ventilation volume...

AI Technical Summary

Problems solved by technology

Because the kiln smoke contains wood gas, wood tar, wood vinegar or bamboo vinegar, etc., and wood tar, wood vinegar or bamboo vinegar are easy to adhere to the inner wall of the negative pressure collection pipe, it is easy to cause the ventilation volume of the pipe to decrease or even block , not only affects the recycling rate of combustible gas in the kiln fume, but also easily causes safety accidents
