Plasma ignition kiln drying device for anthracite kiln

Abstract

A plasma ignition kiln drying device for an anthracite kiln belongs to pulverized coal kilns. A primary air pulverized coal pipe, a base, and a primary thermal cracker are connected in series and communicated through a flange plate; a secondary thermal cracker is sleeved at the outer side part of the primary thermal cracker in a matching manner; a peripheral air pulverized coal pipeline is formed between the primary thermal cracker and the secondary thermal cracker; cyclone blades are assembled inside the peripheral air pulverized coal pipeline; structures taking the shapes of an external cone and an inner cone in the same direction respectively are arranged on the external surface of the tail end part and the internal surface of the tail side part of the primary thermal cracker; a structure taking the shape of an inner cone, matched with the external cone at the tail end part of the primary thermal cracker, is arranged on the inner wall surface of the secondary thermal cracker, so as to form an energy collection opening; and two plasma generators are assembled symmetrically on the base. The device has a novel, reasonable and simple structural design, is reliable to use, and has the advantages of strong adaptation to pulverized coal, high pulverized coal burn-up factor and excellent environment-friendly effect, and low production and operation costs.

Description

technical field [0001] The invention belongs to a pulverized coal kiln, and mainly relates to a device on an anthracite pulverized coal kiln for ignition, kiln drying and normal operation after ignition. Background technique [0002] The kiln drying and ignition of the traditional rotary kiln all use traditional fuel oil, gas and other ignition and oven methods, wasting a lot of high-quality energy. In order to overcome the problems existing in traditional equipment, plasma ignition and kiln ignition devices have been initially developed successfully. However, due to structural design defects, such devices have low burnout, long ignition time, and smoke and dust emissions for ignition of inferior coal and anthracite. Big, polluted environment is serious, that is to say, plasma ignition technology and equipment need to be further improved and improved in terms of environmental protection and energy saving. Contents of the invention [0003] The purpose of the present inven...

In order to overcome the problems existing in traditional equipment, plasma ignition and kiln ignition devices have been initially developed successfully. However, due to structural design defects, such devices have low burnout, long ignition time, and smoke and dust emissions for ignition of inferior coal and anthracite. Large, polluted environment is serious, that is, plasma ignition technology and equipment need to be further improved and improved in terms of environmental protection and energy saving
