Method for producing microfiber glass wool by using exhaust gas generated in yellow phosphorus production process

Abstract

The invention relates to a method for producing microfiber glass wool by using exhaust gas generated in a yellow phosphorus production process, which is characterized by comprising the following steps: spraying water on exhaust gas generated in an electric furnace yellow phosphorus production process to remove liquid phosphorus and dust in the exhaust gas; and after carrying out gas-water separation on the washed exhaust gas, washing with alkali, spraying alkali liquor onto the exhaust gas to regulate the pH value to 6.5-8, sending into the gas distribution disk, and after combustion, blowing flame to glass fiber at a flaming port, thereby obtaining the microfiber glass wool. The invention overcomes the defect of waste of massive exhaust gas in yellow phosphorus industry, provides an effective heat source for microfiber glass wool production industry, creatively combines the two industries, implements circular and economic utilization, and conforms the national policy of energy saving and emission reduction. Meanwhile, the invention establishes an effective solution, and achieves success in practice, thereby greatly lowering the production cost of the microfiber glass wool and enhancing the quality of the microfiber glass wool.

Description

technical field [0001] The invention relates to a method for producing microfiber glass wool from the tail gas produced in the yellow phosphorus production process. Background technique [0002] Yellow Phosphorus, titled White Phosphorus. Due to the action of light and heat, it quickly turns yellow. Pure yellow phosphorus is odorless, but because it reacts with oxygen in the air to produce oxygen and phosphorus oxides, it often has a garlic odor. [0003] Yellow phosphorus has a wide range of uses. Elemental phosphorus can be directly used by the military to produce incendiary bombs, smoke bombs, and tracer bombs. It can also produce dehydrating agents (such as phosphoric anhydride), lubricants, matches, pesticides, plasticizers (such as phosphorus chloride). The deep processing products of yellow phosphorus (phosphoric acid, phosphate) are more widely used. [0004] The raw materials for the production of yellow phosphorus are phosphate rock, silica and coke, which are r...

AI Technical Summary

Problems solved by technology

[0011] At present, combustible gas natural gas or coke oven exhaust gas is used to produce microfiber glass wool. As a high-quality heat source, natural gas is expensive, coupled with large energy consumption, which makes the cost and price of microfiber glass wool remain high.
