Integrated equipment for slag cooling and gypsum drying of thermal power plant

Abstract

The invention is applicable to the technical field of energy conservation, and provides integrated equipment for slag cooling and gypsum drying of a thermal power plant. The integrated equipment comprises a cylinder body, a feeding device and a discharging device, wherein the cylinder body is provided with an inner cavity, a middle cavity and an outer cavity which are concentric, the cylinder bodyis mounted on an equipment bracket and can rotate relative to the equipment bracket, pushing assemblies used for pushing materials are arranged in the inner cavity, the middle cavity and the outer cavity, and the inner cavity communicates with the outer cavity; the feeding device is used for feeding the materials into the cylinder body; and the discharging device is used for outputting the materials outwards. The integrated equipment has the beneficial effects that a traditional process that high-temperature slag cooling and gypsum drying of the thermal power plant are separately carried outis changed, originally lost slag energy is efficiently utilized, waste of heat energy is greatly reduced, the drying cost is reduced, and the occupied space of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an integrated equipment for slag cooling and gypsum drying in a thermal power plant. Background technique [0002] There are two major problems in coal-fired power generation in thermal power plants, one is slag discharge and the other is flue gas emission. The slag is high-temperature slag, and the flue gas contains harmful gases such as sulfur dioxide. [0003] The problem to be solved in the discharge of high temperature slag is the cooling of high temperature slag. At present, power plants generally use circulating water cooling and auxiliary equipment. The equipment used for direct water cooling of slag, such as water-cooled scraper slag extractor, also has indirect water cooling equipment such as CFB power plant drum slag cooler, but these equipment absorb high-temperature slag through cold medium. The heat in the slag is used for heat energy exchange, and the effec...
