AI Technical Summary

Technical Problem

After the existing atmosphere furnace stops working, the waste heat emitted by the resistive wire and the waste heat accumulated inside are difficult to dissipate quickly, resulting in the temperature in the furnace maintaining a high level for a long time, and it is impossible to directly open the furnace door to take out the product, extending the production cycle and causing repeated energy consumption.

Method used

By designing a carbon nanotube production atmosphere furnace for waste gas waste heat recovery, the driving resistance heating tube is used to accurately retract back to the space area between the inner and outer walls of the furnace body, and quickly close the diversion side groove with the sliding baffle to form a physical heat barrier. Through efficient heat exchange between waste gas waste heat and insulation water tank, the rapid dissipation of waste heat and gas preheating is achieved, reducing the power consumption during re-start.

Benefits of technology

The safe removal of carbon nanotube products 35-50 minutes in advance is achieved, which significantly reduces production cycle and energy consumption, and improves production efficiency and energy utilization.

Abstract

The invention provides a carbon nano tube production atmosphere furnace capable of recycling waste gas waste heat, and relates to the technical field of carbon nano tube production, the carbon nano tube production atmosphere furnace comprises a furnace body shell and a protective cover body, the rear end of the furnace body shell is provided with a support, the middle position of the support is provided with a servo motor, and the furnace body shell is installed in the protective cover body; a furnace body inner container is mounted on the inner side of the furnace body shell; a heat preservation water tank is mounted on the outer side of the furnace body shell; a driving pump is mounted at the top of the furnace body shell; four guide sliding rails which are evenly distributed are installed on the inner side wall of the furnace body inner container. A physical thermal barrier is formed by driving the resistance heating pipe to precisely shrink back to a space area between the inner side wall of the furnace body shell and the outer side wall of the furnace body liner and matching with rapid closing of the sliding baffle to the flow guide side groove, so that the temperature gradient decline rate of the atmosphere furnace is increased, and the problems that waste heat emitted by the resistance wire is difficult to dissipate rapidly and energy is wasted are solved. And the temperature in the furnace is maintained at a high position for a long time.
