Vinegar-dreg (or vinasse)-burning hearth structure of fluidized-bed boiler

Abstract

The invention relates to the filed of boiler apparatuses, in particular to a vinegar-dreg (or vinasse)-burning hearth structure of a fluidized-bed boiler. The hearth structure comprises an air opening, a feeding opening, a boiler body, a burning chamber, a heat accumulating layer, a discharge opening, an air discharge opening and a fuel conveying device. Vinegar dregs (or vinasse) are conveyed by the fuel conveying device to enter the feeding opening and finally pass through the discharge opening. A boiler wall and the fuel conveying device are both made of high-temperature-resisting materials. The temperature in the burning chamber is high. Within a primary heating, the majority of the ash carried in the vinegar dregs (or vinasse) is burned. After a secondary heating, the vinegar dregs (or vinasse) releases the majority of heat, and meanwhile, the vinegar dregs (or vinasse) are completely burned out. The hearth structure realizes large-scale quantity-reduction, volume-reduction and non-harmful utilization of the vinegar dreg (or vinasse) resource, and better solves the social, environmental and energy problems caused by the vinegar dregs (or vinasse).

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a fluidized bed boiler furnace structure for burning vinegar (wine) grains, which can be widely used in various engineering companies, large-scale vinegar factories, wineries, paper mills and garbage treatment plants. Background technique [0002] Vinegar (wine) grains are residual waste in the vinegar (wine) industry. In the vinegar (wine) industry, the amount of vinegar (wine) lees produced every day is large, and has low calorific value, high moisture content, high salinity, a large amount of odor, takes up a lot of space and resources, and is slow to dissolve naturally. Characteristics such as serious pollution are produced to the environment, because these characteristics, the processing of vinegar (wine) grains is quite difficult. At present, vinegar (wine) grains are processed, and some studies are used as fertilizer or matrix, and some studies are made into feed by drying...

AI Technical Summary

Problems solved by technology

But the deficiency of this patent is: in the structure such as material ram, slag drop pool, tower type water spray dust collector, water tank type soot collector of burning rice husk boiler, water must be used.

However, the disadvantages of this patent are: the composition structure is very complicated, the control of the upper temperature of the furnace and the outlet steam temperature of the tail heating surface is not easy to realize, the cost is high, and it is difficult to popularize

However, the disadvantage of this patent is that the composition structure is complex, which will inevitably lead to high cost, and it is impractical to use it in a large area in rice-producing areas.
