Efficient methanol high-temperature cracking furnace with automatic carbon burning function

Abstract

The invention discloses an efficient methanol high-temperature cracking furnace with an automatic carbon burning function. The efficient methanol high-temperature cracking furnace comprises a furnacebody. A pipeline area is arranged on one side of the furnace body, a left door, a middle door and a right door are sequentially arranged on the side, away from the furnace body, of the pipeline area from left to right, and a cooling pipe is mounted on the side, away from the middle door, of the pipeline area. A gas outlet of the cooling pipe is connected with a methanol cracking gas pipe; a venting opening, a connecting outlet and a waste discharging outlet are sequentially formed in the side, away from the cooling pipe, of the methanol cracking gas pipe from top to bottom; and the methanol cracking gas pipe is connected with the furnace body through the connecting outlet. According to the efficient methanol high-temperature cracking furnace, a novel nano plate is adopted as a heat preservation layer, so that temperature rise of the outer wall of the furnace body is reduced, energy consumption of the equipment is reduced, and the service life of the equipment is prolonged; the crackingdistance of methanol in the cracking pipe is increased through the U-shaped cracking pipe, accordingly, the cracking efficiency of the cracking pipe is improved, full cracking of the methanol is ensured, and the gas production rate is high; and meanwhile, a device can conduct carbon burning automatically, and the carbon deposit problem of the cracking pipe is solved.

Description

technical field [0001] The invention relates to the field of methanol high-temperature cracking furnaces, in particular to a high-efficiency methanol high-temperature cracking furnace with an automatic charcoal burning function. Background technique [0002] Methanol (Methanol, dried, CH3OH) is the simplest saturated monohydric alcohol with CAS numbers of 67-56-1 and 170082-17-4, molecular weight of 32.04, and boiling point of 64.7°C. Also known as "wood alcohol" or "wood essence". It is a colorless, volatile liquid with alcohol odor. The lowest dose of human oral poisoning is about 100mg / kg body weight, and oral intake of 0.3-1g / kg can be fatal. Used in the manufacture of formaldehyde and pesticides, etc., and used as an extractant for organic matter and a denaturant for alcohol. Usually produced by the reaction of carbon monoxide and hydrogen. [0003] At present, methanol cracking gas is widely used as the main protective gas of the spheroidizing annealing furnace, bu...

AI Technical Summary

Problems solved by technology

[0003] At present, methanol cracking gas is widely used as the main protective gas of the spheroidizing annealing furnace, but the gas production of the current high-temperature methanol cracking furnace is relatively small, and there are problems of incomplete cracking and a large amount of carbon powder, which affect the spheroidization The quality of annealing furnace products, for this reason we have designed a high-efficiency methanol high-temperature cracking furnace with automatic charcoal burning function to solve the above problems
