Abstract

The invention discloses a heat recovery module and a blast-furnace slag heat recovery device composed of the same. The heat recovery module comprises an auger delivery heat exchange device. A water quenching chamber is arranged on the auger delivery heat exchange device. A furnace slag inlet and a superheated steam outlet are formed in the upper portion of the water quenching chamber. The bottom of the water quenching chamber communicates with an inlet of the auger delivery heat exchange device. The auger delivery heat exchange device is connected with a power device. Spray devices are further arranged in the water quenching chamber. Collected furnace slag can pass through the heat recovery module, a medium in the heat recovery module and the furnace slag can exchange energy, the medium absorbing the energy can drive other executing mechanisms, the cooled furnace slag can be directly discharged out, the purposes of saving energy, reducing consumption and lowering the production cost are achieved, and the heat recovery rate of the device can reach 70% or over.

Description

technical field [0001] The present invention relates to the technical field of heat recovery, and more specifically relates to a heat recovery module and a slag heat recovery device composed of the same. Background technique [0002] At present, international and domestic iron and steel enterprises have not found a high-efficiency heat recovery method in the blast furnace slag water quenching process. Domestic iron and steel enterprises all adopt wet water quenching slag. The main processes are OCP method, RASA method, INBA method, TYNA method and MTC method. There is no way to recover the slag heat in these technological methods. The enthalpy of slag is 130 kcal / kg, and about 450 kg of slag is produced for every ton of iron smelting. If calculated based on the annual output of 800 million tons, the annual recoverable heat is equivalent to the heat of 22.6 million tons of standard coal, which is equivalent to about 20 billion yuan . Contents of the invention [0003] T...
