Method and system for extinguishing and cooling activated carbon in front discharge hopper of adsorption tower

Abstract

The invention discloses an method for extinguishing and cooling activated carbon in a front discharge hopper of an adsorption tower. The method comprises the following steps: 1) acquiring a thermal imaging image of a material entering a tail imaging area (3) of a vibrating screen (2) by using a thermal imager (1); 2) judging whether the material entering the imaging area (3) has a high-temperature point or not according to the thermal imaging image, and if it is judged that the thermal imaging image has the high-temperature point, recording the finding position of the material at the high-temperature point in the tail imaging area (3) of the vibrating screen (2); and (3) when the materials at the high-temperature point move into a discharge hopper (5) connected with a discharge port of a conveyor (4), carrying out fire extinguishing and cooling treatment on the high-temperature materials through a spontaneous combustion activated carbon extinguishing and cooling device arranged at the upper part of the discharge hopper (5). High-temperature activated carbon is detected at the tail part of the vibrating screen, and is treated in a flowing and falling state when the high-temperature activated carbon falls into the stock bin, so the problem that high-temperature activated carbon particles are difficult to comprehensively detect and treat is solved, and the safety of the system is improved.

Description

technical field [0001] The invention relates to the detection and treatment of high-temperature activated carbon particles in an activated carbon flue gas purification device, in particular to a method and system for extinguishing and cooling activated carbon in a front discharge hopper of an adsorption tower, and belongs to the technical field of activated carbon flue gas purification. Background technique [0002] The amount of flue gas produced in the sintering process accounts for about 70% of the entire iron and steel process, and the main pollutants in the sintering flue gas are dust, SO 2 , NO X ; In addition, there are a small amount of VOCs, dioxins, heavy metals, etc.; they need to be purified before they can be discharged. At present, the technology of activated carbon desulfurization and denitrification device for treating sintering flue gas has been mature, and it has been popularized and used in China, and good results have been achieved. [0003] The working...
