Description
Technical Field
[0001] The utility model relates to the field of cyclone dust collectors, in particular to a cyclone dust collector for tail gas of a calcining furnace. Background Art
[0002] Heavy soda ash is commonly known as heavy ash, and light soda ash is commonly known as light ash. The chemical composition of light ash and heavy ash is Na 2 CO 3 The main difference between the two is the particle size and bulk density. Light ash is powdery, heavy ash is granular, and the bulk density of light ash is 600Kg / m 3 , the bulk density of heavy ash is 900~1200Kg / m 3 .
[0003] Calcination is the main process of soda ash manufacturing. The calcining furnace is the core equipment in the process. It 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. It is used for ironmaking, recovery of rare metals, catalyst production, environmental improvement, and production of special chemicals. A large amount of 400℃ high-temperature tail gas will be generated during the calcination process. The main harmful components are nitrogen oxides, sulfur dioxide, non-formaldehyde, black ash and a large amount of water vapor, etc., which inevitably carry a large amount of light ash alkali dust. Because of the large amount of water vapor, the alkali dust is easy to adhere to the dust removal equipment, forming a scarring phenomenon. Utility Model Content
[0004] To solve the above problems, the purpose of the utility model is to provide a cyclone dust collector for light ash calcining furnace tail gas, which realizes the removal of alkali dust in the calcining furnace tail gas, thereby achieving the purpose of tail gas purification and solving the scarring phenomenon formed by alkali dust adhesion.
[0005] The technical solution adopted by the utility model to solve the above problems is as follows:
[0006] A cyclone dust collector for tail gas from a light ash calcining furnace comprises a discharge port, an air outlet and a dust collector body, and is characterized in that the dust collector body is divided into an upper straight section and a lower conical section, a volute section is arranged in the straight section of the dust collector, one end of which is a volute inlet, and the other section is connected to the straight section of the dust collector, an outlet straight pipe and an air outlet are arranged inside the straight section; a heating coil is arranged on the volute inlet and the dust collector body as a heating device, the heating coil is coiled on the outer wall of the dust collector body, and the material in the dust collector body is heated and kept warm.
[0007] Furthermore, a hand hole and a vibration device are provided at the upper end of the discharge port, and the vibration device can remove the materials adhering to the inner wall of the dust collector.
[0008] Furthermore, a reinforcement ring is provided on the straight tube section of the dust collector.
[0009] The cyclone dust collector provided by the utility model can effectively solve the problem of materials adhering in the cyclone dust collector, prevent the materials from absorbing water and adhering during the dust removal process by heating the dust collector body, and remove the adhering materials by vibrating the dust collector body.
