Calcium oxide digestion waste heat recovery device
The invention relates to the technical field of chemical production devices, and particularly discloses a calcium oxide digestion waste heat recovery device which comprises a digestion tank, a dust remover and a heat exchanger which are sequentially connected, a stirring mechanism is arranged in the digestion tank, the upper end of the digestion tank is detachably connected with a dust collection cover, and the stirring mechanism comprises a stirring shaft; one end of the stirring shaft extends out of the dust collection cover and is connected with a driving mechanism, the upper end of the dust collection cover is connected with an inlet of the dust remover through an air inlet pipe, and an outlet of the dust remover is connected with the heat exchanger through an air outlet pipe; a water medium pipeline of the heat exchanger is connected with the digestion tank through a water supply pipe to supply high-temperature hot water to the digestion tank. The invention aims to solve the problems that heat generated by calcium oxide digestion during calcium hydroxide production is wasted, and water in a calcium oxide digestion reaction chamber is in non-uniform contact with calcium oxide.
本申请涉及化工生产装置技术领域，具体公开了一种氧化钙消化余热回收装置，包括依次连接的消化罐、除尘器和换热器，所述消化罐内设有搅拌机构，消化罐上端可拆卸连接有集尘罩，搅拌机构包括搅拌轴，以及与搅拌轴可拆卸固定的搅拌叶，搅拌轴一端延伸出集尘罩外部并连接有驱动机构，集尘罩上端通过进风管与除尘器的入口连接，除尘器出口通过出风管与换热器连接，换热器的水介质管路通过送水管与消化罐连接为消化罐送入高温热水。本专利的目的在于解决氢氧化钙生产时氧化钙消化产生热量被浪费，氧化钙消化反应室水与氧化钙接触不均匀的问题。
