Treatment system for yellow phosphorus in soil or phosphorus mud and use method

Abstract

The invention discloses a system for treating yellow phosphorus in soil or phosphorus mud and a use method, and belongs to the technical field of yellow phosphorus treatment systems and methods. A turning and throwing driving motor is mounted at the upper end of the turning and throwing frame device, one end of the gas collecting pipe is communicated with the upper part of the turning and throwing frame device, the other end of the gas collecting pipe is communicated with an inlet of the dust removal device, an air inlet of the fan is communicated with an outlet of the dust removal device, and an air outlet of the fan is communicated with a gas distributor in the absorption tower; the inlet end of the circulating pump is communicated with the lower part of the absorption tower, the outlet end of the circulating pump is communicated with an atomizing nozzle in the absorption tower, one end of the pipeline is communicated with the top end of the absorption tower, and the other end of the pipeline is communicated with the lower part of the chimney. According to the method, the single treatment area is 9 m < 2 >, the lifting height of the turning shaft is controlled through the hydraulic device, so that the turning depth is controlled, the maximum turning depth is 40 cm, toxic smoke generated in the turning process enables negative pressure to be formed in the space of the turning frame device under the action of the draught fan, and smoke overflow is avoided.

Description

technical field [0001] The invention relates to a yellow phosphorus disposal system and a using method in soil or phosphorus mud, and belongs to the technical field of yellow phosphorus disposal systems and methods. Background technique [0002] Yellow phosphorus is highly toxic, and it is a substance that is easy to spontaneously combust. Its ignition point is 40 °C, and it burns violently in oxygen, producing bright flames and thick white smoke, resulting in phosphorus pentoxide. The smoke of phosphorus pentoxide irritates mucous membranes, and has irritating and burning effects on the skin. The maximum allowable concentration is 1 mg / m 3 . [0003] Yellow phosphorus is an important raw material for industrial production. Products made from yellow phosphorus are widely used in many fields such as pesticides, medicines, detergents, food additives, and flame retardants. In the process of yellow phosphorus production or downstream product processing, if it is not properly m...

Problems solved by technology

Both of them do not effectively remove the dust mixed in the flue gas during the construction process, increase the operating load of the flue gas treatment system, and have adverse effects on the disposal efficiency

Because the mixing equipment is placed in a closed greenhouse, personnel still need to enter the closed space for operation during the process, which will also have a certain impact on the health of the operators
