Abstract
The utility model discloses an arrangement structure of a coal molten salt furnace and a heat recovery steam generator, which comprises a coal molten salt furnace and a heat recovery steam generator that are arranged on a furnace bed steel frame, a closed rotary feeder, a back-end ductwork erected between the coal molten salt furnace and the heat recovery steam generator. The back-end ductwork is connected with the coal molten salt furnace and the heat recovery steam generator through pipes respectively. Regarding the utility model, an operating platform of a steamer from 6m through 8m can be saved; civilwork investment can be saved; and high temperature ductwork is shortened. Bottom ash of the heat recovery steam generator and the slag of the coal molten salt furnace can be discharged together; no bottom ash discharge device is needed additionally. The utility model has the advantages of simple structure, economization of investment on civilwork of plants, shortening length of equipment, reduction of thermal losses and reduction of production cost and so on.
Description
Technical field
The utility model relates in a kind of aluminum oxide production process, is used for the coal-fired molten salt furnace of fused salt heating station and the configuration structure of heat recovery steam generator, belongs to coal-fired molten salt furnace technical field.
Background technology
In the prior art, in aluminum oxide production process, the channelization dissolving-out process needs the high temperature thermal medium heat supply, the domestic high-temperature molten salt that generally uses at present.In existing fused salt heating station, main device comprises: coal-fired molten salt furnace 1, back-end ductwork 2, heat recovery steam generator 3, airtight Rotary feeder 4, structure as shown in Figure 1, wherein coal-fired molten salt furnace 1 connects heat recovery steam generators 3 by back-end ductwork 2, heat recovery steam generator 3 is connected with airtight Rotary feeder 4.Because back-end ductwork 2 is horizontally disposed with, so heat recovery steam generator 3 will be installed on the high platform of 6m with airtight Rotary feeder 4, the construction level of station is increased, construction volume strengthens, and the configuration of the pipeline of equipment is complicated, operating personnel's amount of labour strengthens, and the factory and enterprise capital expenditure is increased and the rising of production and operation cost.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, save factory site and material, shortening equipment installation distance, reduce thermal losses, reduce the coal-fired molten salt furnace of capital expenditure and the configuration structure of heat recovery steam generator, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises coal-fired molten salt furnace 1, coal-fired molten salt furnace 1 is installed on the fire grate steel frame 5, on fire grate steel frame 5, heat recovery steam generator 3 is installed, below heat recovery steam generator 3, be provided with airtight Rotary feeder 4, be provided with vertically arranged back-end ductwork 2 between coal-fired molten salt furnace 1 and heat recovery steam generator 3, back-end ductwork 2 is connected with heat recovery steam generator 3 with coal-fired molten salt furnace 1 respectively by pipeline; Be provided with furnace bottom ash handling equipment 6 below coal-fired molten salt furnace 1, heat recovery steam generator 3 connects furnace bottom ash handling equipment 6 by airtight Rotary feeder 4.
Owing to adopted such scheme, the utility model can save steam generator 6m～8m operating platform, once invest to save civil engineering, shorten high-temperature flue length simultaneously.The bottom ash of heat recovery steam generator is got rid of by the furnace bottom ash handling equipment with the slag of coal-fired molten salt furnace, needn't establish other heat recovery steam generator bottom ash tapping equipment in addition.Therefore compare with prior art, the utlity model has simple in structure, save factory's construction investment, shorten the equipment installation distance, reduce thermal losses, advantage such as reduce production costs.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic diagram;
Accompanying drawing 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment of the present utility model: in fused salt heating station factory building, make fire grate steel frame 5, coal-fired molten salt furnace 1 is installed on the fire grate steel frame 5, furnace bottom ash handling equipment 6 is installed below coal-fired molten salt furnace 1, heat recovery steam generator 3 is installed on fire grate steel frame 5, an airtight Rotary feeder 4 is installed below heat recovery steam generator 3, vertical installation back-end ductwork 2 between coal-fired molten salt furnace 1 and heat recovery steam generator 3, back-end ductwork 2 tops are connected with coal-fired molten salt furnace 1 by pipeline, the below of back-end ductwork 2 is connected with heat recovery steam generator 3 by pipeline, airtight Rotary feeder 4 is connected with furnace bottom ash handling equipment 6, by airtight Rotary feeder 4 bottom ash of heat recovery steam generator 3 is disposed to furnace bottom ash handling equipment 6 and carries out ash disposal.
