Abstract

The invention discloses a roller kiln and a smoke exhaust method of the roller kiln based on furnace pressure control. The roller kiln comprises a furnace body with a hearth and a conveying device installed in the hearth. The hearth is provided with one or more smoke exhaust sections. The smoke exhaust sections are divided into a plurality of sub-sections which are sequentially connected in the conveying direction of the conveying device. Each sub-section is provided with a smoke exhaust device with the adjustable exhaust speed. The smoke exhaust method comprises the steps that an optimal smoke exhaust section with the smoke concentration is obtained, and the smoke exhaust devices are adjusted to enable the furnace pressure in the sub-section away from the optimal smoke exhaust section tobe smaller than the furnace pressure in the sub-section close to the optimal smoke exhaust section. The roller kiln and the smoke exhaust method have the advantages that the smoke exhaust efficiency can be improved, and energy consumption and gas consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of heat treatment kiln equipment, in particular to a roller kiln and a smoke exhaust method of the roller kiln based on furnace pressure control. Background technique [0002] The roller kiln is a continuous kiln. By setting different temperature zones, the roller kiln can be divided into three parts: heating section, constant temperature section and cooling section. Roller kilns are widely used in the sintering process of powder materials, ceramics, lithium battery positive and negative materials and other new materials. Taking battery materials as an example, the materials will generate reaction waste gas or volatile gas in the heating section, which needs to pass through the exhaust system Discharge in time. Since the flue gas will carry a large amount of heat (according to calculations, this part of the heat accounts for about 25-35% of the total calorific value of the roller kiln) and is directly disch...
