Abstract

The invention discloses a heat accumulating type furnace gas forced circulation device of an industrial furnace. The furnace gas forced circulation device is arranged on an industrial furnace body and comprises a gas treatment unit. A first gas extracting branch pipeline body and a second gas extracting branch pipeline body are arranged on a gas extracting pipeline, and a first gas blowing branch pipeline body and a second gas blowing branch pipeline body are arranged on a gas blowing pipeline; and the first gas extracting branch pipeline body and the first gas blowing branch pipeline body as well as the second gas extracting branch pipeline body and the second gas blowing branch pipeline body communicate with a first heat accumulator and a second heat accumulator correspondingly under a controlled state, pipelines behind the first heat accumulator and the second heat accumulator are arranged to be matched with a first opening and a second opening of a hearth correspondingly, and gas in the hearth is extracted out or blown into by turns. In the heat accumulating type furnace gas forced circulation device of the industrial furnace, according to the principle of heat accumulator heat accumulating and releasing, furnace gas of an electric furnace and a fuel-fired furnace is subjected to forced furnace gas circulation and forced convection through a draught fan outside the furnace, homogeneity of the furnace temperature is greatly improved and reaches + / -3 DEG C or + / -5 DEG C, and the requirements for special material treatment are met; and forced furnace gas circulation, forced convection and forced agitation are conducted, furnace gas circulation is smooth, and homogeneity of the furnace temperature is remarkably improved.

Description

technical field [0001] The invention relates to an industrial heating furnace, in particular to a regenerative forced furnace gas circulation device for industrial furnaces such as electric furnaces and fuel furnaces. Background technique [0002] For periodic industrial furnaces, such as electric furnaces, fuel furnaces, etc., the furnace temperature uniformity largely depends on the circulation intensity of the furnace gas in the furnace. If the intensity of the furnace gas circulation is high, the furnace temperature uniformity will be high. Low; therefore, in order to improve the uniformity of the furnace temperature, a circulation fan is often installed in the furnace, and the rotation of the fan generates agitation to form a forced furnace gas circulation. These measures are effective when the furnace temperature is low. However, for medium and high temperature furnaces, as the furnace temperature rises, the circulation fan is easily damaged at medium and high tempera...
