Light-weight calcining machine with buried pipe fluidized bed for sodium carbonate

Abstract

The invention discloses naphtha soda pipe laying fluidized bed calcining machine. It solves the problem of that calcining floor area is large; equipment investment is large; furnace inner pre mixing section is scarred; grain state is formed not good; calcining sealing is difficult; and so on. The invention has the advantages of high heat efficiency and simple operation. Its structure is that pipe laying fluidized bed is set on ground jack; and its upper side surface is set feed inlet; its lower part is set feed outlet; the heat exchanger rig is set in it; its bottom is set wind box; its top is set wind outlet; the heat exchanger rig is set air admission cover.

Description

technical field [0001] The invention relates to a light soda ash buried pipe fluidized bed calcination machine for calcination of light soda ash. Background technique [0002] The soda ash calcination industry is a very important category in the current industry. There are two main types of soda ash products, heavy soda ash and light soda ash. The difference in its specifications is mainly due to the difference in physical properties, such as bulk density, particle size and shape, and resting angle. Generally, the density of light soda ash is 500~600kg / m3. [0003] The task of calcining light soda ash is to heat and decompose the wet heavy alkali (mainly composed of sodium bicarbonate) separated by vacuum filter to produce anhydrous sodium carbonate. The main equipment used by domestic soda ash production plants for calcination of light soda ash is mainly steam rotary calcination furnace. The steam calciner is equipped with a steam coil inside the equipment, and the stea...

AI Technical Summary

Problems solved by technology

[0004] Large floor area; large investment in equipment; scabbing of the premixing section in the furnace; poor state of particle formation; difficult calcining and sealing, poor operating environment, large amount of equipment maintenance and other defects

[0005] In practical application, foreign light soda ash fluidized calcination devices have disadvantages such as unstable operation, easy to die, small equipment production capacity and cannot be scaled up, and relatively large dust removal equipment.
