The invention discloses a yellow phosphorus tail gas boiler capable of preventing polyphosphoric acid corrosion. The yellow phosphorus tail gas boiler comprises a combustion boiler main body, a steampipeline and a steel substrate; a fuel gas water tank is installed in the combustion boiler main body, a boiler sealing door is fixedly installed on the inner side of the fuel gas water tank, a fuel gas introducing port is arranged in the inner side of the boiler sealing door, a fuel gas spray gun is fixedly arranged under the fuel gas introducing port, and the left side and the right side of thefuel gas spray gun are each provided with a damping bracket; a steam pocket is connected to the inner side of the steam pipeline, a smoke exhaust pipeline is installed under the steam pocket, and a deacidification device is fixedly installed on the outer side of the smoke exhaust pipeline; and a corrosion-resistant layer is arranged on the left side of the steel substrate, an impact-resistant layer is fixedly installed on the left side of the corrosion-resistant layer, and a decorative paint layer is installed on the left side of the impact-resistant layer. According to the yellow phosphorus tail gas boiler capable of preventing polyphosphoric acid corrosion, the fuel gas spray gun and the deacidification device are adopted, and therefore the corrosive substance generating quantity can bedecreased.
Description
technical field [0001] The invention relates to the technical field of formaldehyde detection, in particular to a yellow phosphorus tail gas boiler for preventing polyphosphoric acid corrosion. Background technique [0002] At present, in the technical field of using yellow phosphorus tail gas to generate electricity in China, only a very small number of boiler manufacturers have tried to recover the waste heat of the yellow phosphorus tail gas, and very few have succeeded, resulting in most yellow phosphorus manufacturers until today. We can only watch a large amount of energy being lit as sky lanterns, which not only wastes energy but also causes serious environmental pollution. Effective recycling of yellow phosphorus tail gas can reduce the production cost of yellow phosphorus and greatly reduce pollution emissions, which is in line with the current "energy saving emission reduction” trend. [0003] However, the boilers currently on the market for burning yellow phospho...
