The invention discloses a heat tube recovering system for waste heat of a high-temperature solid bulk cargo. The heat tube recovering system consists of a bulk cargo conveying system (1), a left inner heat tube (2), a right inner heat tube (3), a left outer heat tube (4), a right outer heat tube (5), a transmission device (6), an air supply system (7), a vacuum component (8), an electric cabinet (8) and a vacuum pump (10), wherein the transmission device (6) drives an auger spiral slice (1-2) to rotate so as to turn over and push forward the entered high-temperature slag, simultaneously, working media of the inner heat tube and the outer heat tube are heated, evaporation and heat absorption are performed to cool down the slag, the working medium steam is condensed by blowing air in the finned tubes of the inner and outer heat tubes, and heat of condensation is released to heat up air. The heat tube recovering system has the following advantages: 1, closed-type dry-process temperature reduction of the slag is adopted to preheat air through waste heat, so that water, energy and land are saved and emission is reduced; 2, auger turnover propulsion and the heat exchange technology of the inner and outer radial heat tubes are adopted to achieve quick heat exchange and high efficiency; 3, the inner heat tube, the outer heat tube and two working media are adopted to solve the difficult problem that lowest slag temperature and higher air preheating temperature rise can not be realized at the same time.
Description
technical field [0001] The technical solution of the present invention belongs to the field of heat exchange equipment, specifically, it belongs to the field of heat exchange equipment with condensation and evaporation of intermediate heat transfer medium in the closed pipe leading into or passing through the channel wall, according to the International Patent Classification Law, belonging to F28D 15 / 02. Background technique [0002] my country's coal-fired slag waste heat is generally not recovered. The proportion of its heat is not large, accounting for only 1% to 2% of the calorific value of coal, but the total amount of coal is huge, and it is also a valuable resource that cannot be ignored. In addition, coal-fired slag is mostly treated by wet method, which wastes precious water resources and pollutes the environment. In addition to the waste heat of coal-fired slag, industries such as steelmaking, ironmaking, and cement also have a large amount of waste heat from sol...
