Vertical roasting stove

Abstract

The invention discloses a vertical roasting stove. The vertical roasting stove comprises a vertical stove body, wherein a rotary table is mounted at the bottom of the stove body and is connected with a rotation driving device; a wind distributing splitter is mounted on the rotary table; discharging channels are arranged on the side surface of the bottom of the stove body; inlets of the discharging channels are positioned in the outer side of the rotary table; unloading valves are mounted on the discharging channels; baffles are mounted on the side wall of the stove body around the wind distributing splitter, and are positioned at the inlets of the discharging channels; the lower ends of the baffles are compactly abutted against the top surface of the rotary table; wind inlet pipes are arranged at the bottom of the stove body; wind distributing holes are formed in the wind distributing splitter, and are communicated with wind inlet pipes. The vertical roasting stove disclosed by the invention has the advantages that the vertical roasting stove can perform destructive distillation and calcination on briquettes or sludge pellets, and perform drying and cooling at the same time; the whole production process can be performed continuously, so that the production efficiency is high; when the briquettes are destructively distilled, the situation that coal gas is mixed with air can be effectively avoided.

Description

technical field [0001] The invention relates to a dry distillation equipment, in particular to a vertical roasting furnace. Background technique [0002] my country's coal resources are rich and widely distributed, but the domestic application level of coal resources is relatively low, and most of them are directly burned and discharged from loose coal. The energy utilization rate is not high, and it will cause pollution to the environment. One of the main reasons is that in order to improve the utilization rate of coal, bulk coal can be made into briquettes, and then roasted, dry-distilled and coked to obtain dry-distilled coke. At the same time, raw coal gas can be recovered during the dry-distillation process. Boilers and fixed beds in chemical fertilizer plants and other equipment can realize clean coal combustion and reduce environmental pollution caused by coal-fired fields; raw coal gas can be separated from chemical products such as gas, tar, benzene, naphthalene and o...

AI Technical Summary

Problems solved by technology

However, most of the existing equipment that can roast briquettes or sludge pellets cannot achieve continuous production, and the production efficiency is low, so it is difficult to meet the needs of the production process. Moreover, most of the existing roasting equipment can only realize the dry distillation function. The steps of drying and cooling of briquettes or sludge pellets need to be completed in conjunction with other equipment and production steps, and when the existing roasting equipment performs dry distillation of briquettes, some volatiles are carried in the exhausted flue gas, especially in the When carbonizing bituminous coal, the volatile content of the emission is high, which makes it difficult to meet environmental protection standards
