Problems solved by technology
However, there are the following problems: firstly, the separation effect of the sorting chamber on large particles is not obvious, and the high-concentration airflow may entrain a large number of large particles into the next stage, and the cooling effect of the sorting chamber on large particles is not good. The lower part is the air distribution device, which is not conducive to fluidized cooling

The invention belongs to effluent incinerator auxiliary equipment, and particularly relates to a wind and water combined type multi-level cooling slag cooler. A one-level cooling air chamber is arranged in the middle of the slag cooler, a slag cooler cavity chamber is divided into a one-level cooling cavity in the upper portion and a two-level cooling cavity in the lower portion, a two-level cooling air chamber is vertically connected to the lower portion of the one-level cooling air chamber and communicated with the one-level cooling air chamber, and the one-level cooling air chamber is communicated with a main air chamber through a rotating support internally provided with a ventilation channel and a rotating shaft internally provided with a ventilation channel. A water cooling system is composed of slag scraper blades and cooling water pipelines. The one or more levels of cooling water pipelines are arranged at the bottom of the two-level cooling air chamber, and a set of slag scraper blades fixedly connected with the rotating shaft are arranged above each level of cooling water pipeline. The slag cooler can carry out fine and rough separation, efficient liquid-state slag cooling and fast condensed slag crushing, large slag is prevented from being produced, secondary cooling is carried out on the slag, and the discharged slag of a boiler can be cooled to the greatest extent.
Description
technical field [0001] The invention belongs to auxiliary equipment for waste liquid incinerators, and in particular relates to a wind-water composite multi-stage cooling slag cooler. Background technique [0002] The waste liquid incineration boiler is an efficient and low-cost combustion device for treating hazardous waste liquid, and its slag discharge system is crucial to the operation of the boiler. Due to the combustion of low-quality fuel (hazardous waste liquid) with high water content, the waste liquid contains a large amount of alkali metal salts after combustion, and the amount of hot slag discharged is large, which is easy to cause heat loss and heat pollution, so the slag discharge system is very important for the operation of the boiler. Efficiency and environmental impact cannot be underestimated. [0003] The high-temperature bottom slag discharged from the waste liquid incineration boiler has a slag discharge temperature close to the furnace combustion temp...
