Description

Yellow phosphorus grain slag flushing system

Technical Field

The utility model relates to a yellow phosphorus preparation field especially relates to a yellow phosphorus grain slag dashes sediment system.

Background

At present, yellow phosphorus production in China is mostly unit equipment of ten thousand tons per year, the equipment is large, and a large occupied area is needed. In the production process of yellow phosphorus, phosphate ore forms slag, namely waste slag after being heated. About 8-10 tons of waste residues are generated every 1 ton of yellow phosphorus is produced, the amount of the waste residues is large, and the waste residues are in a high-temperature molten state at 1300 ℃. At present, the waste residue is treated by directly flowing the waste residue into a waste residue cooling pool through a chute, then a set of travelling equipment with a grab bucket is built above the waste residue cooling pool, and a residue bucket is built near the waste residue cooling pool. After the waste residue meets water for cooling, the cooled waste residue is grabbed into the residue bucket through the travelling crane equipment, then the transport vehicle is driven into the lower part of the residue bucket, and the waste residue is discharged into the transport vehicle from the residue bucket and is pulled away.

The existing waste residue treatment mode has the following problems:

1. because the waste residue from the yellow phosphorus furnace is in a high-temperature melting state of 1300 ℃, a large amount of high-temperature and high-pressure steam is generated after the waste residue meets cooling water, and because the waste residue cooling tank is open, the high-temperature heat energy of the waste residue is completely lost through the generated large amount of water vapor, and the waste residue cannot be effectively recycled.

2. Because the temperature of the slag from the yellow phosphorus furnace reaches 1300 ℃, and the temperature of the cooling water is low, the temperature difference between the slag and the cooling water is very large, the high-temperature slag of the yellow phosphorus furnace can be rapidly cooled after meeting the cooling water, so that the high-temperature slag is exploded into fine particles, and the particles are pea-sized. Because the slag particles of the blast cracks are small, the grab bucket is difficult to grab the waste slag from the cooling pool, and water is stopped to feed after the slag discharge is finished, and then the waste slag in the waste slag cooling pool is manually cleaned.

3. Because the waste residue cooling bath is bulky, along with intaking always, but the circulation speed of water is slow, and the waste residue gets into the rigidity of waste residue cooling bath through the chute, waste residue egress opening department needs a large amount of cooling water just to make the waste residue obtain fully cooling, the waste residue is by can not in time clear up, lead to the waste residue to pile up, the high temperature waste residue that continuously falls into can produce a large amount of steam and push the cooling water open, lead to the cooling water can not in time contact with the contact of high temperature waste residue, the waste residue fuse is in the same place, meet water and just produce the explosion very easily again. In order to prevent explosion, the current practice is to increase the size and depth of the slag cooling tank as much as possible and increase the water storage capacity, so the larger the volume of the slag cooling tank is.
