Technical Field
[0001] The utility model relates to the technical field of flue dampers, in particular to a flue damper of a high-strength petroleum coke calcining furnace. Background Art
[0002] Calciner is a thermal equipment that heat treats carbon raw materials (such as coke, anthracite, etc.) at high temperature to improve the performance of raw materials. Our company uses calciner to manufacture petroleum coke. During the calcination process, high-temperature flue gas is discharged through the flue. A flue gate is hung at the flue outlet to control the discharge opening. Petroleum coke refers to the raw coke produced by delayed coking unit, also known as ordinary coke, and there is no corresponding national standard. At present, domestic production enterprises mainly produce according to the industry standard SH0527-92 formulated by the former China Petrochemical Corporation (see the attached table for details). This standard mainly classifies petroleum coke according to its sulfur content. The first-grade product, No. 1 coke, is suitable for making ordinary power graphite electrodes in the steelmaking industry, and is also suitable for use as carbon for aluminum in the aluminum smelting industry; No. 2 coke is used as electrode paste and production electrode for electrolytic cells (furnaces) in the aluminum smelting industry; No. 3 coke is used to produce silicon carbide (abrasive material) and calcium carbide (calcium carbide), as well as other carbon products, and is also used to manufacture anode bottom blocks for aluminum smelting electrolytic cells and for carbon lining bricks or furnace bottom construction for blast furnaces.
[0003] As disclosed in the authorization announcement No. 111, a flue damper for a petroleum coke calcining furnace is disclosed, including a refractory layer and a reinforcement layer distributed at intervals, the refractory layer includes four layers, the reinforcement layer includes three layers, the reinforcement layer is distributed between adjacent refractory layers, the thickness of the refractory layer near the two ends of the flue damper is not less than 15mm, the refractory layer includes a mixture of crushed refractory brick particles and refractory cement, the size of the refractory brick particles in the refractory layer is less than 6mm, the reinforcement layer includes a metal mesh, the pore size of the reinforcement layer on both sides is smaller than the pore size of the reinforcement layer in the middle, and a lifting ring is fixed at one end of the flue damper. This flue damper uses refractory brick particles and refractory cement as the main materials, but it has low strength during use and high manufacturing cost. For this reason, we propose a high-strength flue damper for a petroleum coke calcining furnace to solve the problem of low strength and high manufacturing cost of traditional dampers.
