Problems solved by technology

[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 effectively and economically utilize them will be a very problem that needs to be solved.
[0006] There are two types of effluent treatment methods, one is to arrange the effluent to flow in the channel on the kiln mouth, and spray water into the flowing effluent at the same time to cool and decompose it; the other is to drain the effluent Put it into a container, such as a stuffy tank car, and transport the stuffy tank container to other areas by car or rail car, but it only realizes cooling and transportation, and there is no recovery of high-temperature heat energy

Embodiment 1

[0039] Embodiment 1. Heat pipe waste heat utilization system on the discharge flow channel

[0040] figure 1 The discharge outlet 2 on the kiln 1 discharges the discharge 3 to the flow channel 4, and the evaporation end 7 of the heat pipe is arranged around the flow channel and at the bottom, and the condensation ends 9 of a plurality of heat pipes are arranged in the container 8, and the container is provided with There are inlet 6 and outlet 5. The heat pipe absorbs the heat energy of the discharge through the evaporation end of the heat pipe and then transfers the heat to the condensation end 9 of the heat pipe. The condensation end is set in the container. The outflow is to the outside, and the condensing end of the heat pipe exchanges heat with the fluid to realize the application of the heat energy of the exhaust.

Embodiment 2

[0041] Embodiment 2. Heat pipe waste heat utilization system for transporting stuffy tanks

[0042] figure 2 The discharge outlet 2 on the kiln 1 in the middle discharges the discharge 3 into the transport tank 10, and the evaporation end 7 of the heat pipe is arranged at the inner bottom and the surrounding of the transport tank, and the condensation ends 9 of multiple heat pipes are arranged in the transport tank. 8, the transport tank is provided with an inlet 6 and an outlet 5, and the heat pipe absorbs the heat energy of the discharge through the evaporation end of the heat pipe and then transfers the heat to the condensation end 9 of the heat pipe. The condensation end is set in the container, and the fluid flows from the transport tank The inlet enters the transport stuffy tank, and then flows out from the outlet to the outside, and the heat pipe condensing end exchanges heat with the fluid to realize the application of the heat energy of the discharge.

Abstract

The invention provides a heat tube type kiln discharge afterheat utilization system. The heat tube type kiln discharge afterheat utilization system comprises at least one kiln and a container, wherein the container is arranged outside a discharge port of the kiln, and is positioned on a discharge runner or conveying container; at least two cavities are formed in the container; one is a fluid cavity, and the other one is a heat tube cavity; a fluid inlet and a fluid outlet are formed in the fluid cavity; one end of a heat tube is arranged in the fluid cavity, and the other end is arranged in the heat tube cavity; the heat tube cavity is arranged around the discharge runner or on the conveying container for absorbing the heat energy of discharges; the heat energy is transmitted to the fluid cavity through the heat tube; and the heat exchange is performed with a fluid through the fluid cavity. The heat tube type kiln discharge afterheat utilization system performs the heat exchange between the kiln discharges and the heat tube, uses the heat tube for recovering the heat energy of the high-temperature discharges, uses the fluid heat exchange for realizing the recovery and the utilization of the heat energy, and realizes the recovery of high-temperature afterheat of the kiln with high temperature, large scale, low cost and high efficiency.

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...
