On-line hot plate furnace co-processing device and method for co-processing hazardous waste

Abstract

The invention belongs to the technical field of solid waste treatment, and in particular relates to an on-line hot plate furnace for co-processing hazardous wastes, including a heat exchange device, one end of the heat exchange device is connected to the hot plate furnace, the other end is connected to a decomposition furnace, and also includes steam A generating unit, a steam engine, a power conversion unit and an abrasive unit, the abrasive unit is equipped with pulverized coal, part of the pulverized coal processed by the abrasive unit is sent to the hot plate furnace, and the other part of the pulverized coal is sent to the decomposition furnace. The invention also provides a method for using the device, which includes steps of heat collection, steam generation, and torque generation by the steam engine. The method of the invention collects the heat released by reducing the temperature of the combustion gas in the hot plate furnace through the heat exchange device. , the pulverized coal is ground and processed, the method makes full use of energy, saves costs, and improves the combustion quality of the on-line hot plate furnace.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to an on-line hot plate furnace for co-processing hazardous wastes and a method for using the same. Background technique [0002] The use of cement kilns to co-process and dispose of bulk pollutants generated by urban development such as municipal solid waste, sludge, and hazardous waste is a new approach based on existing pollutants. From the perspective of the cement industry itself, the co-processing of cement kilns is a development direction that is more in line with the current adjustment and transformation of cement enterprises. It can expand the regional social functions of cement enterprises, improve the development dilemma of pure product production-oriented development of cement enterprises, and create additional benefits for the environment and society. benefit. From the perspective of strengthening environmental protection and effectively reduc...

Problems solved by technology

[0011] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an on-line hot plate furnace co-processing hazardous waste device to solve the problem that the prior art does not utilize the temperature difference between the hot plate furnace and the decomposition furnace , did not collect and utilize part of the heat released by the temperature difference; the existing technology only controls the temperature in the calciner by controlling the amount of pulverized coal, and needs to adjust the amount of pulverized coal added to the calciner at all times; the existing technology cannot use heat The temperature difference between the pan furnace and the calciner grinds the pulverized coal, and the coal powder is unevenly distributed in the hot pan furnace and the calciner, resulting in uneven heat release, insufficient work quality and work efficiency. The method of using the device is provided
