The invention discloses chromium slag detoxification and innocent treatment equipment and method based on a fixed bed, and relates to the technical field of chromium slag detoxification and innocent treatment. The equipment comprises a fixed bed reactor, a screening cylinder, a crushing cylinder and a lifting cylinder, integrates crushing, screening, lifting and circulating, does not need external complex crushing equipment, and reduces the pretreatment difficulty and cost of the refuse derived fuel. The method comprises the following steps: by taking the refuse derived fuel as an additive, drying, crushing and screening, mixing the refuse derived fuel with qualified particle size with chromium slag in a fixed bed reactor, and carrying out pyrolytic reaction under the protection of nitrogen to reduce hexavalent chromium into trivalent chromium. According to the chromium slag detoxification equipment, through sequential transmission coupling of the lifting auger, the linkage mechanism and the vertical vibration mechanism, multi-element driving input of a single power source is achieved, the equipment cost is saved, chromium slag detoxification treatment of treating waste with waste is achieved, the treatment cost is low, high efficiency and stability are achieved, Cr (III) reoxidation can be effectively avoided, and harmless, reduction and resourceful treatment of chromium slag is achieved.

This invention discloses a sulfur and chlorine fixation agent for waste-derived fuel, its application, and the waste-derived fuel itself. The raw materials for the sulfur and chlorine fixation agent include the following components by weight: 50-80 parts calcium-based desulfurization ash; 5-30 parts sodium-based desulfurization ash; 5-30 parts quicklime; and 3-15 parts oxidant. This invention also provides the application of the sulfur and chlorine fixation agent for waste-derived fuel in waste-derived fuel and the waste-derived fuel itself. The sulfur and chlorine fixation agent of this invention can significantly reduce the volatilization rate of S and Cl during the combustion of waste-derived fuel, making it suitable for the subsequent utilization of waste-derived fuel in incinerators and gasifiers. It can co-process calcium-based and sodium-based desulfurization ash from steel plants, achieving the effects of waste-to-waste treatment, low investment, and rapid results.

The application discloses a garbage derived fuel processing device, which comprises a box body with a feeding port, at least two toothed rollers are arranged in the box body and rotate in opposite directions, a feeding pipe is arranged on the feeding port of the box body, one end of the feeding pipe away from the box body is connected with a feeding hopper, a rotating shaft is rotatably arranged on one end of the feeding pipe close to the feeding hopper, a plurality of turnover blades are arranged on the rotating shaft in a circumferential direction, a rotating rod extending along the length direction of the feeding pipe is rotatably arranged on the top surface of the feeding pipe, at least one water spraying cover and at least one medicine spraying cover are arranged on the rotating rod, and the water spraying cover is arranged on the side of the medicine spraying cover away from the feeding port. The application simplifies the processing technology after crushing, increases the range of liquid flushing and disinfection of the garbage, improves the uniformity of the mixed liquid and garbage, and improves the cleaning and disinfection effect.
