Description

Technical Field

[0001] The utility model relates to the technical field of incineration treatment, in particular to a fly ash cleaning and dehydration integrated device. Background Art

[0002] With the rapid development of the economy, the problem of garbage disposal is becoming more and more serious. At present, the largest way to dispose of garbage in my country is landfill, but the landfill occupies a large amount of land, and the land resources are becoming increasingly scarce. As a result, the proportion of incineration in garbage disposal has increased year by year. The use of incineration to treat garbage has the advantages of reducing volume and quantity, reducing land occupation, utilizing waste heat, and achieving resource utilization, and has been widely used. In the process of garbage incineration, incineration fly ash will be produced, which mainly refers to the capture of the flue gas purification system and the bottom ash settled at the bottom of the flue and chimney. The municipal waste incineration (MSWI) fly ash generated after the incineration of municipal domestic garbage accounts for about 2%-5% of the original garbage mass. As garbage incineration disposal becomes more and more common, the production of garbage incineration fly ash in my country is also increasing. Due to the presence of a large number of heavy metals, dioxins and other toxic and harmful substances in fly ash, it has been included in the "National List of Hazardous Wastes" with the number HW18, so incineration fly ash must be properly disposed of.

[0003] The integrated fly ash cleaning and dehydration device disclosed in the Chinese utility model patent application publication specification CN216881008U simplifies the fly ash acid-washing and water-washing decalcification process, improves the processing efficiency, and reduces the cost and pressure of subsequent fly ash processing. However, when the fly ash enters the cleaning chamber, it is directly poured into the feed port, which causes the fly ash to be blocked at the feed port, affecting normal feeding, and it is impossible to clean while feeding, resulting in a low cleaning efficiency.

[0013] (III) Beneficial effects

[0014] The utility model provides a fly ash cleaning and dehydration integrated device, which has the following beneficial effects:

[0015] 1. The fly ash cleaning and dehydration integrated device has the effect of preventing fly ash from being blocked when it enters the cleaning chamber through the arrangement of the second motor, the second rotating shaft and the rotating rod. When in use, the fly ash is poured into the cleaning chamber from the feed hopper. During the pouring process, the second motor is turned on to drive the second rotating shaft to rotate, and the second rotating shaft drives the rotating rod to rotate to break up the fly ash entering therefrom, thereby preventing the fly ash from being blocked at the feed port, thereby achieving the purpose of avoiding blockage.

[0016] 2. The fly ash cleaning and dehydration integrated device has the effect of continuously cleaning the fly ash through the arrangement of the sewage pump, the water pipe, the dehydration chamber, the water channel, the filter screen and the return water tank. When in use, the fly ash continuously enters the cleaning chamber from the feed hopper. During the entry process, water and various liquid medicines enter the cleaning chamber through the liquid medicine water inlet. The first motor drives the first rotating shaft to rotate, and the first rotating shaft drives the stirring rod to rotate, thereby stirring the fly ash and water in the cleaning chamber. The cleaning of the fly ash is completed during the stirring process. At the same time, the sewage pump is turned on, and the mixed liquid in the sewage pump is pumped into the water pipe to make the mixed liquid enter the dehydration chamber. After the mixed liquid enters the dehydration chamber, the fly ash is separated by the action of the filter screen, and the liquid enters the water channel through the filter screen, and then from The return water tank re-enters the cleaning chamber, so that the liquid medicine is reused and circulated, and fly ash is continuously added. This process makes the amount of liquid medicine in the cleaning chamber at 80%. After the fly ash enters the cleaning chamber, it needs to pass through the liquid medicine before being pumped away by the sewage pump, and then the cleaning of the fly ash can be completed. In order to improve work efficiency, relevant personnel in time can appropriately change the size of the dehydration chamber so that the dehydration chamber can store more fly ash. After the fly ash is processed, the cleaned fly ash enters the heater. At this time, the heater is turned on to dry and dehydrate the fly ash in the dehydration chamber, and then the agglomerated fly ash is cleaned. When the device is used, fly ash can be added while cleaning. Compared with cleaning in batches, a lot of time is saved and the loss of liquid medicine is reduced, thereby achieving the purpose of improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
