Problems solved by technology

Due to the high water content of the garbage, the ignition conditions are poor. In order to improve the drying strength and burnout rate of the garbage, the operation mode of increasing the primary air temperature and increasing the excess air coefficient of the primary air is generally used, but these methods will result in poor cooling effect of the grate pieces. Increase exhaust smoke loss, NO x Adverse effects such as high emission concentration

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 and figure 2 , the present invention provides a garbage incinerator with a movable intermediate arch structure, the incinerator is mainly composed of an incinerator drying section 1, a combustion section 2, a burnout section 3, an incinerator grate located in the furnace, and an incinerator front arch 9. Rear arch 4, slide rail 5, fixing piece 7, hydraulic cylinder 8 and middle arch 6 of the incinerator.

[0029] The middle arch 6 of the incinerator is arranged between the front arch 9 and the rear arch 4 in the furnace. Slide rail 5 is set below the middle arch 6 of the incinerator, and the bottom surface of the middle arch 6 is movably placed on the slide rail 5. The slide rail 5 is installed outside the side wall of the furnace, and the middle arch 6 is moved into the hearth through the side wall of the incinerator. The midd...

Abstract

The invention relates to a garbage incinerator with a movable middle arch structure. A sliding rail is arranged below a middle arch of the incinerator, the bottom face of the middle arch is movably arranged on the sliding rail, the sliding rail is installed outside a side wall of a hearth, and the middle arch is moved into the hearth through the side wall of the incinerator; the middle arch is located above a combustion section of the incinerator, a front flue gas channel is formed by the middle arch and a front arch in the hearth, and a rear flue gas channel is formed by the middle arch and a rear arch; a hydraulic cylinder drives the middle arch through a fixing part, and the middle arch is moved in or out of the hearth from the side wall of the incinerator under drive control of the hydraulic cylinder. Through the design of the movable middle arch, the middle arch can be moved in and out, the size of the middle arch is changed, the cooling air capacity in the middle arch is changed, therefore, distribution of garbage combustion radiant heat is adjusted, the combustion temperature of the combustion section is increased, the drying effect is enhanced, and the garbage burn-off rate is increased.

Description

technical field [0001] The invention relates to garbage incineration technology, in particular to a garbage incinerator provided with a movable intermediate arch structure. Background technique [0002] my country's garbage generally contains water and high ash content. Due to the high water content of the garbage, the ignition conditions are poor. In order to improve the drying strength and burnout rate of the garbage, the operation mode of increasing the primary air temperature and increasing the excess air coefficient of the primary air is generally used, but these methods will result in poor cooling effect of the grate pieces. Increase exhaust loss, NO x Adverse effects such as high emission concentration. [0003] Through investigation and research, there is a large difference in the calorific value of waste in winter and summer in China. The temperature of the incinerator in operation is low in winter and high in summer; improve. [0004] In view of this, technicia...
