Description

一种垃圾焚烧发电厂灰渣收集装置Ash collection device for garbage incineration power plant 技术领域Technical field
本发明涉及一种垃圾焚烧发电厂辅助设置，尤其涉及一种垃圾焚烧发电厂灰渣收集装置。The invention relates to an auxiliary installation of a garbage incineration power plant, in particular to an ash collection device of the garbage incineration power plant.
背景技术Background technique
随着城市的发展，人口的聚集，城市每天产生的垃圾量在不断增加，加剧了垃圾焚烧发电厂处理垃圾的压力。在垃圾焚烧发电厂的生产运营过程中，由于垃圾成分复杂，垃圾在燃烧过程中将产生大量飞灰。大量飞灰经水平烟道落入灰斗后经输灰机排走。水平烟道的落灰温度较高，而且还带有一定黏度，容易附着在灰斗内壁，常造成灰斗堵灰。目前的处理方法是：人工通过灰斗人孔门进行捅灰、掏灰疏通。With the development of cities and the concentration of population, the amount of garbage produced in cities is increasing every day, which intensifies the pressure on garbage incineration power plants to dispose of garbage. In the production and operation of waste incineration power plants, due to the complex composition of waste, a large amount of fly ash will be generated during the combustion of waste. A large amount of fly ash falls into the ash hopper through the horizontal flue and is discharged by the ash conveyor. The ash falling temperature of the horizontal flue is relatively high, and it also has a certain viscosity, which is easy to adhere to the inner wall of the ash hopper, which often causes the ash hopper to block the ash. The current treatment method is: stab the ash and dredge the ash manually through the ash bucket manhole door.
问题是，操作人员在进行捅灰及掏灰的过程中，飞灰容易从人孔门向外掉落造成漏灰。由于飞灰含有大量的重金属及二恶英等有害物质，飞灰泄漏不仅影响现场工作环境，而且严重危害现场人员的身体健康，甚至导致环境两次重度污染，清理工作量大，而且，由于飞灰温度高，还容易导致操作人员发生高温烫伤的危险。The problem is that in the process of stabbing and digging out the ash, the fly ash will easily fall from the manhole door and cause ash leakage. Since fly ash contains a large amount of heavy metals and dioxin and other harmful substances, the leakage of fly ash not only affects the working environment on site, but also seriously endangers the health of on-site personnel. The ash temperature is high, and it is also easy to cause the danger of high temperature burns to the operators.

具体实施方式detailed description
图1为现有技术一个实施例的结构示图。图中显示，现有技术中，一种垃圾焚烧发电厂灰渣收集装置，按照落灰由上往下掉落的方向，依次包括灰斗1、落灰管2及输灰机3，所述落灰管2的上端口与所述灰斗1的出料口连接而下端口接入到所述输灰机3，落灰经所述落灰管2落入所述输灰机3中，在所述灰斗1上还开设人孔门1.1。Fig. 1 is a structural diagram of an embodiment of the prior art. The figure shows that in the prior art, an ash collection device for a garbage incineration power plant includes an ash hopper 1, an ash pipe 2 and an ash conveyer 3 according to the direction in which the ash falls from top to bottom. The upper port of the ash falling pipe 2 is connected with the discharge port of the ash hopper 1, and the lower port is connected to the ash conveying machine 3, and the ash falling into the ash conveying machine 3 through the ash falling pipe 2, A manhole door 1.1 is also opened on the ash hopper 1.
在垃圾焚烧发电厂的生产运营过程中，由于垃圾成分复杂，在燃烧过程中将产生大量飞灰，大量飞灰经水平烟道落入灰斗1之后经输灰机3排走。水平烟道的落灰温度较高，而且还带有一定黏度，容易附着在灰斗内壁，常造成灰斗1堵灰。目前的处理方法是：操作人员通过人孔门1.1进行捅灰、掏灰疏通。In the production and operation process of waste incineration power plants, due to the complex composition of waste, a large amount of fly ash will be produced during the combustion process, and a large amount of fly ash will fall into the ash hopper 1 through the horizontal flue and be discharged by the ash conveyer 3. The ash falling temperature of the horizontal flue is relatively high, and it also has a certain viscosity, which is easy to adhere to the inner wall of the ash hopper, which often causes the ash hopper 1 to block the ash. The current treatment method is: the operator uses the manhole door 1.1 to stabbing and digging out the ash.
但问题，操作人员在进行捅灰及掏灰的过程中，飞灰容易从人孔门向外掉落造成漏灰,也称为落灰。由于飞灰含有大量的重金属及二恶英等有害物质，漏灰不仅影响现场工作环境，而且严重危害现场人员的身体健康，甚至导致环境两次重度污染，清理工作量大，而且，由于飞灰温度高，还容易导致操作人员发生高温烫伤的危险。But the problem is that in the process of stabbing and digging out the ash, the fly ash is easy to fall from the manhole door to cause ash leakage, which is also called ash falling. Because fly ash contains a large amount of heavy metals and dioxin and other harmful substances, ash leakage not only affects the working environment on site, but also seriously endangers the health of on-site personnel. The high temperature also easily leads to the danger of high temperature burns for the operators.
图2、图3为本发明第一个实施例的结构示意图，其中图2为立体图、图3为主视图。图中显示，与现有技术不同的是，本例中，还设置漏灰收集装置，按照落灰由上往下掉落的方向，所述漏灰收集装置依次包括格栅板4，收集斗5，输灰管6及插板阀7，所述格栅板4设置在所述人孔门1.1的下侧，所述输灰管6的上端口与所述收集斗5连接而下端口接入到所述输灰机3，所述人孔门1.1泄漏出来的漏灰掉落在所述格栅板4然后进入所述漏灰收集装置。还设置人工操作台9，所述人工操作台9包括平台9.1、支架9.2、防护栏9.3、爬梯9.4、围板9.5。图中显示，在输灰管6上还设置有法兰8.1、8.2用于管道的安装和连接。2 and 3 are schematic diagrams of the structure of the first embodiment of the present invention, in which FIG. 2 is a perspective view, and FIG. 3 is a front view. As shown in the figure, different from the prior art, in this example, a leakage ash collection device is also provided. According to the direction in which the ash falls from top to bottom, the ash leakage collection device includes a grid plate 4 and a collection bucket in turn. 5. The ash conveying pipe 6 and the inserting plate valve 7, the grid plate 4 is arranged on the lower side of the manhole door 1.1, the upper port of the ash conveying pipe 6 is connected with the collecting bucket 5 and the lower port is connected When entering the ash conveyor 3, the ash leaked from the manhole door 1.1 falls on the grid plate 4 and then enters the ash collection device. A manual operation platform 9 is also provided, and the manual operation platform 9 includes a platform 9.1, a bracket 9.2, a protective fence 9.3, a ladder 9.4, and a fence 9.5. As shown in the figure, flanges 8.1 and 8.2 are also provided on the ash conveying pipe 6 for pipe installation and connection.
当发生灰斗1堵灰时，操作人员可以通过爬梯9.4爬上平台9.1，打开人孔门1.1对灰斗1的内部进行捅灰、掏灰疏通。如果发生漏灰事件，掉落的漏灰被所述漏灰收集装置收集，可以有效确保确保操作人员人身安全及环境卫生，避免工作环境受到再次污染。When the ash hopper 1 is blocked by ash, the operator can climb the platform 9.1 by climbing the ladder 9.4 and open the manhole door 1.1 to stabbing and digging out the ash inside the ash hopper 1. If an ash leakage event occurs, the fallen ash leakage is collected by the ash leakage collection device, which can effectively ensure the personal safety and environmental sanitation of the operators, and prevent the working environment from being polluted again.
