The utility model relates to a sealed air structure of a garbage discharge port of a garbage incineration boiler, belonging to the technical field of garbage incineration boiler equipment, which comprises a garbage entry port into the boiler, the discharge port is square, the discharge port is surrounded by a furnace wall, the discharge port is a furnace, the furnace is a mixture of garbage and coal, and the left, right and bottom sides of the discharge port. A total of 15_30 nozzles are arranged on the furnace wall, and 5_10 nozzles are evenly arranged on the left side, right side and lower wall of the lower orifice. The nozzles penetrate into the furnace wall from outside the furnace wall and are vertically arranged with the furnace wall. The nozzle is not at the end of the nozzle. The nozzle is in the furnace and near the lower orifice, and the other end of the nozzle is connected with the fan. Pressure sealed gas; when the fan starts, the high-pressure sealed gas in the nozzle is sprayed into the furnace through the nozzle to seal the discharge port; the beneficial effect of the utility model is that the waste discharge port can be sealed, the boiler room will not emit a pungent odor, and does not affect the surrounding environment and the health of the staff.

一种垃圾焚烧锅炉垃圾下料口密封风结构
本技术为一种垃圾焚烧锅炉垃圾下料口结构,特别涉及一种垃圾焚烧锅炉垃圾下料口密封风结构,属于垃圾焚烧锅炉设备
技术介绍
垃圾焚烧锅炉的给垃圾焚烧系统中,垃圾进入锅炉处有一个长方形下料口。垃圾在送入炉内前要进行发酵,发酵后的垃圾产生刺鼻的气味,在送入炉内的过程中,由于垃圾焚烧锅炉处于微正压状态运行,垃圾下料口密封不佳,使得整个锅炉房内会散发出刺鼻的气味,不但影响着周围环境,而且影响着工作人员的身体健康。
技术实现思路
本技术的目的是针对上述垃圾焚烧锅炉垃圾下料口结构的现有技术中,存在垃圾下料口密封不佳,整个锅炉房内会散发出刺鼻的气味,影响周围环境和工作人员身体健康的缺陷,提供了一种垃圾焚烧锅炉垃圾下料口密封风结构,可以达到垃圾下料口能密封住,锅炉房内不会散发出刺鼻的气味,不影响周围环境和工作人员身体健康的目的。为了实现上述目的本技术采取的技术方案是:一种垃圾焚烧锅炉垃圾下料口密封风结构,包括垃圾进入锅炉的下料口,所述下料口为方形,下料口四周为炉壁,下料口内为炉膛,炉膛内为垃圾和煤的混合物;在下料口的左、右两侧和底部的炉壁上共设置 ...
【技术保护点】
1.一种垃圾焚烧锅炉垃圾下料口密封风结构,包括垃圾进入锅炉的下料口,所述下料口为方形,下料口四周为炉壁,下料口内为炉膛,炉膛内为垃圾和煤的混合物,其特征在于:在下料口的左、右两侧和底部的炉壁上共设置有15‑30个喷管,下料口的左侧、右侧和下部的炉壁上各均匀设置有5‑10个喷管,喷管自炉壁外穿入炉壁内、与炉壁垂直设置,喷管未端为喷口,所述喷口在炉膛内、靠下料口处,喷管另一端与风机连接,喷管内有高压密封气体。
