Abstract
Description
Technical Field
[0001] This utility model relates to the field of incinerator slag treatment technology, specifically a slag and dust sorting and collection device for a waste incinerator. Background Technology
[0002] Waste incineration is a technology that burns waste at high temperatures. Waste incineration is a process that uses high-temperature oxidation to convert organic matter in waste into inorganic substances such as carbon dioxide, water, and ash. Inside the incinerator, waste undergoes a violent oxidation reaction under certain temperature, oxygen, and residence time conditions, releasing a large amount of heat energy.
[0003] After the waste is completely burned on the grate, the resulting slag is discharged to the slag discharge machine. The slag discharge machine collects the slag until a certain amount is reached, and then discharges the slag.
[0004] Water-sealed slag dischargers are common slag discharge equipment in waste incineration systems. After the slag is hoisted into the slag trough and comes into contact with water, it is rapidly cooled. The slag is then scooped out by a slag remover. However, because the slag is in a high-temperature state when discharged, it generates a large amount of steam and slag dust upon contact with water, which cannot be handled. This results in high internal pressure and high temperature, causing the steam and slag dust to overflow from the slag discharge port with the airflow, affecting the workshop environment and making it impossible to effectively recover the slag dust. Therefore, this application is proposed to solve the above-mentioned problems. Utility Model Content
