Embodiment 1

[0042] Embodiment 1, have the hexagonal solid block of three temperature control spring mechanisms

[0043] figure 1 The hexagonal solid block shown is composed of 70% steel slag, 20% copper ore powder, 3% graphite powder, and 7% aluminum oxide. They are mixed and formed. There is a groove in the rectangular block Road 2. There are three temperature control spring mechanisms on three sides. 3. The temperature control spring can be started after 450 degrees. In the shell and tube heat exchanger, heat is exchanged to realize the utilization of temperature.

Embodiment 2

[0044] Embodiment 2, the hexagonal solid block that has a thermal expansion mechanism

[0045] figure 2 It is a hexagonal solid block, which is composed of 30% power plant coal ash, 65% gold mine tailings powder, and 5% graphite powder. They are mixed and shaped, and heated at 1200 degrees. A thermal expansion mechanism 4 is provided, and when the temperature rises, the liquid inside begins to expand, which pushes the thermal expansion mechanism to expand, so as to realize the separation of solid particles and discharge.

[0046] Heat transfer and heat exchange at 10-1000 degrees can be applied.

Embodiment 3

[0047] Embodiment 3, semicircular solid block with concave structure

[0048] image 3 The solid block with a concave structure shown is composed of 60% iron slag and 40% quartz sand. After adding it to a temperature of 800 degrees for 30 minutes, the two concave structures can be combined into a cylinder, and the cylinder and After the discharge is mixed, it is separated by solid-liquid separation equipment, and the separated heat storage body is loaded into the shell-and-tube heat exchanger, and the heat energy is recovered by the heat exchanger, and the recovered solid particles are reused.

Abstract

The invention aims to provide a heat accumulator for high-temperature recovery of kiln discharges, which can realize the recovery of high-temperature kiln afterheat with high temperature, large scale, low cost and high efficiency, and is suitable for the heat accumulation at a temperature of 10-1500 DEG C. The heat accumulator consists of metal or nonmetal or a mixture thereof, and is mixed with the kiln discharges in a kiln outlet; the heat energy exchange is performed between the heat accumulator and the kiln discharges; after the heat accumulator reaches a set temperature, the heat accumulator is separated from the discharges, then, a heat exchanger of the heat accumulator is used for exchanging heat to realize the recovery and the utilization of the heat energy; and the heat accumulator can recover the heat energy of the kiln discharges of 30-1200 DEG C. The invention further aims to provide an application method of the heat accumulator for high-temperature recovery of the kiln discharges; the heat accumulator is mixed with the discharges; and after the heat accumulator reaches the set temperature, the heat accumulator is separated from the discharges to realize the recovery and the utilization of afterheat.

Description

technical field [0001] The invention relates to heat energy utilization, in particular to a method for recovering high-temperature waste heat of a kiln by using a heat storage body. Background technique [0002] There are many discharges from industrial kilns, such as steel slag from steelmaking plants, which have a lot of waste heat, but the existing technology cannot recycle the waste heat. [0003] At present, only water can be used to cool the steel slag, and then recover the heat energy of the slag flushing water, but the temperature of the slag flushing water is only 60-90 degrees, and high temperature utilization cannot be realized. [0004] In fact, the temperature of the discharged steel slag can reach 300-800 degrees, and there are technical problems on how to recover the waste heat. [0005] The discharge of industrial kilns, steel slag, etc., and the tailings formed by various mine developments have accumulated as above, and there are hidden dangers. How to effe...
