Abstract

The invention discloses a device for absorbing heat energy from combustion of yellow phosphorus with heat transfer oil, comprising an oil tank, a yellow phosphorus combustion furnace, a steam generator, an air heater, an evaporator, a circulating pump and a valve that are connected in a loop. Heat transfer oil is used as a heat-conducting medium to absorb the heat energy from combustion of yellow phosphorus and transfer to the evaporator, the steam generator and the air heater so as to prepare concentrated solution or steam or dry air. The device of the invention meets the technological requirements of heat absorption at different temperatures, which remarkably reduces the operation pressure of high-temperature heating system and the safety requirements, and improves the reliabilities of the system and equipment. The heat-conducting medium of the invention can be recycled so as to not only provide the heat needed in the technological process, but also dispense with a special coal-fired boiler, an exhaust-heat boiler and a cooling water device, therefore the cost for absorbing and reusing the heat energy from combustion of yellow phosphorus is greatly reduced, and the energy is saved. The device of the invention has favorable economic, social and environmental benefits.

Description

technical field [0001] The invention belongs to heat energy recovery mechanical technology, and relates to a device for absorbing yellow phosphorus combustion heat energy by heat conduction oil. Background technique [0002] Phosphoric acid and phosphates are an important part of the chemical industry. The production methods of phosphoric acid are divided into thermal phosphoric acid and wet phosphoric acid. Because thermal phosphoric acid has the advantages of high product concentration and less impurities, it has been widely used in phosphorus chemical enterprises. The main process of the production process of thermal phosphoric acid is yellow phosphorus melting, yellow phosphorus burning and hydration absorption. Chinese patent CN201010127125.2 The method for directly producing food-grade high-purity phosphoric acid from yellow phosphorus is that liquid phosphorus is continuously supplied at the bottom of the combustion tower under the condition of a certain water level...
