Yellow phosphorus and cement integrated production method and device

Abstract

The invention discloses a yellow phosphorus and cement integrated production method and device. Phosphorus slag and heat produced when yellow phosphorus is produced are utilized, an argillaceous raw material in cement clinker production is replaced by the phosphorus slag, and the heat serves as a heat source in the raw material calcining process. Compared with a traditional yellow phosphorus production technology, the cost of the special place for stacking the waste slag is avoided, waste water for cooling the waste slag is eradicated, and resource and energy waste is prevented. Compared with a traditional cement clinker production technology, the high-temperature melting waste slag produced by the yellow phosphorus directly serves as high-temperature melting materials of cement, the purpose of re-utilization of the yellow phosphorus waste slag resource is achieved, the process that the cement raw material is subjected to temperature increasing and melting to be converted into clinker is omitted, the high-temperature heat energy of the waste slag is utilized, the waste slag resource is reused while energy is saved, the use of coal in the calcining process is reduced, resources are saved, and the waste gas produced by the coal is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an integrated production method of yellow phosphorus and cement and a production device thereof. Background technique [0002] Yellow phosphorus is a basic chemical raw material, which is widely used in national defense, electronics, food, fertilizer, chemical industry and other fields. Its uniqueness is irreplaceable by other raw materials. At present, the domestic production capacity is excessive, but it is indispensable. [0003] Cement is a basic building material, widely used in industry, agriculture, transportation and other fields, and is one of the indispensable basic materials for national construction. [0004] However, yellow phosphorus and cement are both high-energy and high-pollution production enterprises. They both have a high-temperature melting (above 1400°C) process and a high-temperature cooling stage at the same time, resulting in...

Problems solved by technology

[0004] However, yellow phosphorus and cement are both high-energy and high-pollution production enterprises. They both have a high-temperature melting (above 1400°C) process and a high-temperature cooling stage at the same time, resulting in a lot of waste of heat energy, especially in the yellow phosphorus production process. , the discharge of high-temperature molten slag is the largest heat loss, and consumes a large amount of water required for cooling the slag
