Embodiment 1

[0030] A high-temperature lava heat exchange system, basically as attached figure 1 As shown, it includes an exchange tank 1, a heat exchanger 6 and a pump for driving liquid metal circulation. The pump is either an electromagnetic pump or a mechanical pump 5, and the mechanical pump 5 is selected in this embodiment. Both the liquid inlet and the liquid outlet of the mechanical pump 5 are provided with electric heating rods (not shown) for heating the liquid metal, so that the electric heating rods and the mechanical pump 5 form an auxiliary heating system.

[0031] The upper part of the exchange box 1 is connected with a feed hopper 2, the feed hopper 2 is an inverted cone, the lower part of the exchange box 1 is connected with a discharge port 7, and at least one layer of rollers 11 is connected to the exchange box 1 in rotation. In this embodiment The middle roller 11 is one layer. as attached figure 2 , Attached Figure 3 and Attached Figure 4 As shown, the roller 11 i...

Embodiment 2

[0041] The difference from Embodiment 1 is that, as attached Figure 7 As shown, there are at least two scrapers 12, two of which are selected in this embodiment, and the lower part of the scraper 12 is provided with a rotating shaft 121, and the rotating shaft 121 is fixedly connected with the power part fixed on the exchange box 1, and the power part is a stepper Any one of the motor or the servo motor, the present embodiment selects a stepping motor (not shown in the figure). When the stepping motor is started, the stepping motor will drive the scraper 12 to rotate towards the outer cylinder, and the blade portion of the scraper 12 will be against the outer wall of the outer cylinder.

[0042] combined with Figure 8 As shown, the outer wall of the outer cylinder is provided with a number of chutes distributed in an annular array along its axial direction. The elastic part fixedly connected with the outer wall of the outer cylinder is any one of a tension spring, a compre...

Abstract

The invention relates to the technical field of heat exchange equipment, and discloses a high-temperature lava heat exchange system. The system comprises an exchange box, a heat exchanger, and a pumpfor driving liquid-state metal to circulate; a layer of roller is at least rotationally connected into the exchange box in the vertical direction; a scraping piece butting against the roller is fixedon the exchange box; a heat exchange cavity for enabling the liquid-state metal to pass through is formed in the roller; the heat exchange cavity communicates with the pump and the heat exchange cavity; and the heat exchange cavity communicates with the pump. The high-temperature lava heat exchange system is simple in structure, and can scrape high-temperature lava attached on an outer cylinder toachieve heat exchange between the high-temperature lava and the liquid-state metal.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a high-temperature lava heat exchange system. Background technique [0002] High-temperature lava refers to the waste slag produced in the industrial smelting process, such as iron slag produced after ironmaking, which is molten at high temperature, so it is also called high-temperature lava, and the temperature can generally reach 1000-1700 °C. In the existing smelting process, the waste slag is usually cooled naturally, then crushed, and then reused. This not only makes the cooling time longer, but also the heat of the high-temperature waste slag cannot be fully utilized, resulting in energy Loss. [0003] Based on the above problems, our company has developed a high-temperature lava heat exchange system, and at the same time developed a liquid metal as a heat exchange medium. The liquid metal is an alloy composed of gallium, indium, bismuth, aluminum, iron, ma...
