Description

Technical Field

[0001] The utility model belongs to the technical field of pollutant disposal facilities, and in particular relates to an entrance and exit spray washing device for a temporary closed construction operation room of a mud phosphorus storage site. Background Art

[0002] Mud phosphorus refers to waste with no residual value generated during the production of yellow phosphorus. Landfilled and stored mud phosphorus will cause underground soil to be infiltrated and polluted, which poses a very high environmental risk. In particular, the land where the mud phosphorus is stored no longer meets the conditions for other uses, and the mud phosphorus storage site must be excavated, cleaned, disposed of, and transformed. During the excavation and cleaning of the mud phosphorus storage site, fire and smoke (whose main components are phosphorus pentoxide and slight fluoride) will occur, which will cause secondary pollution to the construction site, the surrounding environment, and the air, and will pose a great threat to the human body and the environment. In response to this situation, effective secondary pollution prevention and control measures must be taken, such as building a temporary closed construction operation room as an operating space at the storage site. The construction material is corrosion-resistant metal or plastic material. The operating space must be in a negative pressure state during construction, and the collected smoke must be handled uniformly. In terms of excavation construction requirements, the excavator and vehicle close the movable door after entering the operating space, and load the vehicle while excavating the pollutants. After the storage tank is loaded, it must be sealed. After vehicles loaded with pollutants leave the construction site through the movable door, they must immediately enter the designated area for repeated cleaning to ensure that there are no pollutants remaining on the outside of the vehicle and the outside of the tank containing mud phosphorus and pollutants before leaving the construction site. Traditional manual cleaning is time-consuming and labor-intensive. If automatic car washing equipment is built, the structure is complex, the cost is high, and it is not convenient to build and circulate as a temporary facility. Existing car washing equipment is divided into two types: mobile and fixed, depending on whether the spray washing is mobile. The mobile type has a complex structure, and the fixed type requires the construction of more spray washing pipes and nozzles, and the structure is also relatively complex. For this reason, it is very necessary to develop a spray washing device for the entrance and exit of a temporary closed construction operation room in a mud phosphorus storage site that has a simple structure, is easy to build, and can be thoroughly cleaned.
