Example Embodiment

[0031] The following description only represents a specific embodiment of the present invention, which is only for further describing the present invention, but does not limit the present invention.

[0032] Completed a split type electric heating furnace, including an upright circular stainless steel inner cylinder with a diameter of 0.5m and a furnace body height of 3m. The inner cylinder is covered with furnace tiles, and the distance between the furnace tiles and the outer wall of the inner cylinder is 35mm; the furnace tiles are divided into two lobes in the circumferential direction. The furnace tile is an arc-shaped heat insulation board made of polycrystalline mullite; each furnace tile is equipped with a chromium-nickel resistance wire inside, and there are several horizontal grooves on the inside of the furnace tile, and the chromium-nickel resistance wire is wound into a spiral The shape is placed in the groove, and the two ends of the resistance wire are led out of the...

Abstract

The invention provides a kind of resolution type heating furnace, involves an electric heating stove and its decomposes on in the catalyst carrier the application. Including inner liner, stove tile, outside stove tile thermal insulation material, furnace shell; The stove tile divides into at least two petals in the circumference direction, each petal stove tile alone is loaded with the electric heating part, the thermal insulation material, each petal stove tile joint on a pulley, the pulley may slippery leave along the track outside the tube body, enables around the tube body each petal stove tile to be allowed to separate with the furnace body, is advantageous for controls warm, overhaul. The invention may use in each kind to need to control the temperature the heating furnace, specially takes the catalyst carrier decomposing furnace.

Description

Technical field: [0001] The invention relates to a heating furnace, in particular to an electric heating furnace and its application in the decomposition of catalyst carriers. Background technique: [0002] Usual electric heating furnace is to wrap a heating wire from top to bottom outside the whole furnace. If the heating wire breaks down, it is necessary to disassemble all the insulation layers and furnace tiles for maintenance and replacement. This kind of furnace is currently used for the decomposition of the catalyst carrier. When the electric heating part is repaired, it is time-consuming, labor-intensive, and material-intensive. The cycle is long and the production is delayed. Invention content: [0003] The technical problem to be solved in the present invention is: [0004] When the traditional electric heating furnace is overhauled, all the furnace tiles need to be dismantled, resulting in high cost and long cycle time, and the whole electric heating wire cannot...
