Embodiment 1

[0032] Referring to Fig. 2, this embodiment provides a liquid slag sensible heat short-distance recovery equipment with granulation chamber, granulation wind, back blowing and grate bed, which is composed of a closed granulation chamber 1, at one end of the granulation chamber A slag chute 103 is provided, and a downwardly inclined fan-shaped slag distributing pan 104 is provided below the slag chute, a granulation air nozzle 105 is provided under the slag distributing pan, and a high-temperature air inlet 106 is provided on the top of the granulation chamber; On the opposite side of the blowing nozzle, the other end of the granulation chamber is provided with a blow-back nozzle 107; below the granulation chamber, there is a grate bed 4 which can move the granulated slag, and the air chamber 7 under the grate bed is provided with a high-temperature cooling air blower. Air inlet 5. A slope 401 is provided at the head end of the grate bed, a lower hopper 8 is provided at the end...

Embodiment 2

[0035] Referring to Fig. 3, the structure of the liquid slag sensible heat short-distance recovery equipment given in this embodiment is basically the same as that in Embodiment 1, except that the granulated slag can be reflected back to the grate bed more accurately and evenly, and the top shell of the granulation chamber The inner surface is a three-sided reflective surface composed of an arc surface 108 and two flat surfaces 109, which further shortens the recycling distance.

Embodiment 3

[0037] Referring to Fig. 4, this embodiment provides a liquid slag sensible heat short-distance recovery equipment with a granulation chamber, a granulation wind, a blowback, a grate bed and a low-temperature recovery chamber. two parts.

[0038] The upper part is composed of two parts, the granulation chamber 1 and the low-temperature recovery chamber 2. The granulation chamber is composed of an arched water-cooled top shell 101 and a water-cooled vertical wall 102. A slide A slag channel 103, a downwardly inclined fan-shaped slag distributing pan 104 is provided below the slag chute, a granulation air nozzle 105 is provided below the slag distributing pan, and a high-temperature air inlet 106 is provided on the top of the arched water-cooled top shell. The end of the granulation chamber (the right end in the figure) is provided with a blow-back nozzle 107 . The included angle between the injection direction of the granulation wind nozzle and the horizontal plane is adjustab...

Abstract

The present invention relates to a liquid slag sensible heat short-distance recovery method and its equipment. It is characterized by that in the downwards falling process of high-temperature liquid slag said method uses reverse high-pressure high-speed granulating air to promptly and quickly cool and impact the liquid slag to obtain pulverized granulated slag, and makes the granulated slag quickly fed into granulating chamber, and reflected from its internal surface and fallen on the grate type slag-conveying mechanism, under the action of granulating air and back blowing air the heat quantity in the liquid slag can be quickly discharged and collected, so that the recovery distance can be greatly shortened.

Description

technical field [0001] The invention relates to a method for recovering sensible heat of liquid slag in industries such as metallurgy, thermal power, and chemical industry, in particular to a short-distance recovery method and equipment for sensible heat of liquid slag, which belongs to a waste heat recovery method and equipment. Background technique [0002] In industries such as metallurgy, thermal power, and chemical industry, a large amount of waste—waste slag in a high-temperature, liquid state is produced, which is collectively referred to as “liquid slag” in the present invention. [0003] For example: in the metallurgical industry, only a part of this liquid slag is transported to the slag yard by wind quenching, water quenching or natural cooling to recover its granulated slag as building materials. Heat is all lost and wasted in vain. According to relevant information, the total amount of blast furnace liquid slag in my country's metallurgical industry is nearly 1...
