Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, and in particular to a fly ash treatment device for waste incineration power plants. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the amount of urban waste has increased dramatically. Waste incineration, as an effective waste treatment method, has been widely used in some large cities due to its advantages such as good volume reduction and high energy recovery rate. However, waste incineration produces a large amount of fly ash, which contains high levels of various harmful metals and salts such as Cd, Pb, Zn, and Cr that can be leached by water. Improper handling will cause serious secondary pollution to the environment. Furthermore, the heavy metals in fly ash are difficult to degrade naturally and are easily leached by water, thus polluting groundwater, soil, and air. The accumulation of heavy metals can cause long-term harm to ecosystems and human health.

[0003] The existing method for treating fly ash involves spraying water mist into the air to adsorb the fly ash, which is then discharged through a drainage device. However, the current method of collecting and discharging fly ash requires a long period of adsorption and dilution with clean water. If the wastewater is not filtered and the fly ash is collected and discharged directly, it will pollute the environment.

[0004] Therefore, it is necessary to provide a new fly ash treatment device for waste incineration power plants to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fly ash treatment device for waste incineration power plants.

An inclined plate is fixedly connected inside the collection body. An opening is provided on one side of the collection body, and a transmission pipe is fixedly connected to the opening side.

[0009] The filter structure includes a filter body, a collection body, and a spraying device installed on the top of both the filter body and the collection body. Multiple sets of slide rails are fixedly connected to the inner wall of the filter body, and collection baskets are slidably connected to the top of each set of slide rails. Two sets of collection baskets are provided, each with a through hole on its front side. A rotating shaft is rotatably connected inside each through hole. Scrapers are fixedly connected to the bottom of each rotating shaft, and a rotating handle is fixedly connected to the front end of each rotating shaft. A filter screen is installed at the bottom of the collection basket. Two outlets are provided on the front side of the filter body.

[0010] Preferably, a base is fixedly connected to the bottom of the filter body, which can support the filter body.

[0011] Preferably, a guide plate is fixedly connected to one end of the transmission pipe, and the wastewater can be transmitted to the filtration structure through the guide plate.

[0012] Preferably, both sets of collection baskets are fixedly connected to the front side with a pull rod, which allows the collection baskets to be easily removed.

[0013] Preferably, a collection tray is fixedly connected to the bottom of the filter body, and a drain pipe is fixedly connected to one side of the collection tray, through which the filtered wastewater can be discharged.

[0014] Preferably, water pipes are fixedly connected to one side of both sets of spraying devices, and clean water can be input into the spraying devices through the water pipes.

[0015] Preferably, a controller is fixedly connected to one side of the filter body, and a power cord is fixedly connected to one side of the controller, so that the entire device can be operated intuitively through the controller.

[0017] Compared with related technologies, the fly ash treatment device for waste incineration power plants provided by this utility model has the following beneficial effects:

[0018] This utility model provides a fly ash treatment device for a waste incineration power plant;

[0019] 1. This utility model can collect fly ash through a set collection structure. Before the fly ash needs to be treated, the fly ash is collected into the flue pipe by a fan. The spraying device on the top of the collection body is controlled by the operation controller to spray clean water. The fly ash flowing through the flue pipe is adsorbed by the water mist. The wastewater flows through the inclined plate to the transmission pipe and then to the filter body, thereby realizing the collection of fly ash for convenient subsequent treatment.

[0020] 2. This utility model can filter and collect fly ash through a set filter structure. When fly ash needs to be treated, the spraying device installed on the top of the filter body can be controlled by the operation controller to spray clean water to further dilute the sewage flowing through the transmission pipe. Larger fly ash particles in the sewage are collected and accumulated by the filter screens at the bottom of the two sets of collection baskets. After the fly ash is collected, the collection basket is pulled by the pull rod and taken out from the outlet. The fly ash on the filter screen is scraped off by rotating the rotating handle and collected. After the water in the fly ash evaporates, it forms a solid, thereby realizing the collection and treatment of fly ash. Attached Figure Description
