Furnace slag split-flow heat exchange device

Abstract

The application relates to a slag split flow heat exchange device, which includes an airtight casing. A slag collection chamber is arranged inside the airtight casing. A heat exchange material bed for carrying and transporting slag is arranged in the slag collection chamber. There is an air distribution plate, the slag collection chamber includes a heat exchange chamber located above the air distribution plate, a shunt cavity is provided on the inside of the side wall of the airtight shell, and a heat storage structure for absorbing slag radiation heat is provided at the upper end of the air distribution plate. Structurally, there is a channel connecting the heat exchange chamber and the distribution chamber, and the lower end of the air distribution plate is provided with an air hole connecting the slag collection chamber and the distribution chamber. The slag shunt heat exchange device of the present application can divert the airflow before entering the air distribution plate area to avoid excessive wind speed in the air distribution plate area; the heat storage structure at the top of the air distribution plate can be used to absorb radiant heat during slag granulation , the cooling air flow passing through the distribution cavity carries this part of the heat into the heat exchange cavity, and the recovery and utilization efficiency of waste heat is high.

Description

【Technical field】 [0001] The application relates to a slag split flow heat exchange device. 【Background technique】 [0002] At present, in the industrial field, smelting furnace equipment produces a large amount of slag during the production process. These slags are often accompanied by a large amount of waste heat. According to technical data, this part of waste heat resources accounts for more than 30% of its fuel consumption. It can be seen that the utilization of slag waste heat exists. Great potential. The utilization of waste heat from slag can not only reduce energy consumption per unit of product, but also reduce environmental pollution. Therefore, the utilization of waste heat from slag has considerable economic and social benefits. [0003] In the prior art, when the wind quenching method is used to recover the waste heat of the slag, there are the following disadvantages: 1. Due to the high wind speed in the area of ​​the air distribution plate, the particles wil...
