Online hot plate furnace hazardous waste co-processing device and using method

Abstract

The invention belongs to the technical field of solid waste treatment, and particularly relates to an online hot plate furnace hazardous waste co-processing device which comprises a heat exchange device and further comprises a steam generation unit, a steam engine, a power conversion unit and a grinding unit, wherein one end of the heat exchange device is connected to a hot plate furnace, and the other end of the heat exchange device is connected to a decomposition furnace; pulverized coal is filled in the grinding unit; and one part of the pulverized coal processed by the grinding unit is fed into the hot plate furnace, and the other part of the pulverized coal is fed into the decomposition furnace. The invention further provides a using method of the device, the using method comprises the steps of collecting heat, generating steam, generating torque through a steam engine and the like. The heat released by reducing the temperature of combustion gas in the hot plate furnace is collected through the heat exchange device, pulverized coal is levigated, energy is fully utilized, cost is reduced, and the combustion quality of the online hot plate furnace is improved.

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 co-processing hazardous waste device and a use method. Background technique [0002] The use of cement kilns to co-process and dispose of bulk pollutants produced by urban development such as municipal solid waste, sludge, and hazardous waste is a new way based on existing pollutants. From the perspective of the cement industry itself, the co-processing of cement kilns is more in line with the current development direction of the adjustment and transformation of cement enterprises. It can expand the regional social functions of cement enterprises, improve the 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 reducing the hazards of pollutants, the...

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
