Description
Technical field
Yellow phosphorus reclaimer field more particularly to a kind of efficient Yellow phosphorus recovering device.
Background technique
China possesses the most abundant phosphate rock resource in the world, and reserves, yield and the occupation rate of market of yellow phosphorus occupy the world
First.Phosphorus smelting process can generate a large amount of tail gas.But due to yellow phosphoric tail gas complicated component, purification difficulty is big and investment is more,
Therefore tail gas is mostly directly vented in the past and burns by phosphorus production enterprise, on the one hand causes the waste of the energy, resource, on the other hand
It will cause environmental pollution, do not meet national energy-saving environmental protection and requirement of developing a circular economy.The recycling of mud zero is mainly used at present
The method of evaporative condenser, the fusing point of yellow phosphorus are 44.1 DEG C, and boiling point is 280 DEG C, and dew point is 180.7 DEG C, will according to the characteristic of yellow phosphorus
Mud phosphorus is heated to boiling point in the case where completely cutting off air, and yellow phosphorus becomes gaseous state, then will import condensation containing gaseous yellow phosphorus
System makes yellow phosphorus liquefy by cooling water, is deposited in collection trench bottom.But the rate of recovery of common distillation condensation method yellow phosphorus is insufficient
70%, because the yellow phosphorus steam in device is low with the mixability of cooling water, the condensation of yellow phosphorus steam is incomplete, this is not only wasted
Yellow phosphorus resource, the pernicious gas emitted also pollute the environment.
Utility model content
The purpose of this utility model is yellow phosphorus steam and cooling in cooling yellow phosphorus steam for existing yellow phosphorus collection device
The undercompounding of water, yellow phosphorus steam condense incomplete problem, and providing one kind keeps yellow phosphorus steam and cooling water well-mixed
Device.
The technical solution adopted in the utility model is as follows:
A kind of efficient Yellow phosphorus recovering device, including collecting tank, the collecting tank are provided with air inlet and air outlet, the receipts
Collection slot lower end is provided with slag notch and water outlet, limited valve is arranged at the top of the gas outlet, the collecting tank is internally provided with
Collecting tank is divided into multiple regions by multiple partitions, partition, is provided with multiple absorption towers above collecting tank, with string between absorption tower
Connection mode connects, and spray head is provided at the top of the absorption tower, and an absorption is provided on each region in the multiple region
Tower.
Using this scheme, yellow phosphorus steam is entered in collecting tank by air inlet, due to being provided with partition in collecting tank, and
By the water level control of cooling water more than the lower edge of partition, so yellow phosphorus steam can only be from mutually flowing, then between absorption tower
Steam comes out from absorption tower enters gas outlet, yellow under the action of pressure limiting valve gravity since limited valve being arranged at the top of gas outlet
Phosphorus steam can not rush gas outlet, when yellow phosphorus steam is enough in device, increase pressure in device, when the thrust that gas generates
Greater than pressure limiting valve gravity when, pressure limiting valve, which is boosted at this moment gas, can go out gas outlet, simultaneously because the Huang inside device
Phosphorus steam releases a part, and pressure reduces in device, and component increases the pressure in pressure limiting valve falling device again.It is intermittent in this way
Be discharged yellow phosphorus steam purpose be that residence time is longer in the device in order to make yellow phosphorus steam, so as to more fully with absorption
The cooling water that top of tower spray head sprays is sufficiently mixed, and improves the rate of recovery of yellow phosphorus.
Wherein, the shape on the absorption tower is reciprocal folds.
Since the shape on absorption tower is reciprocal folding, so yellow phosphorus steam constantly changes the direction of motion in absorption tower, make
The cooling water that flowing velocity becomes very slowly make in this way the spray head at the top of yellow phosphorus steam and absorption tower to spray is sufficiently mixed
It closes, reaches the higher yellow phosphorus rate of recovery.
Wherein, the side at the top of the gas outlet is provided with lateral projection.-
Wherein, the bottom of the pressure limiting valve is interior hook-shaped.
Wherein, the collection trench bottom is horizontal by 60-70 ° of angle.
Using this scheme, makes the impurity in collecting tank that can slide to slag notch, be convenient to clean.
Wherein, the gas outlet connects exhausting scrubber system.
Using this scheme, the gas of device gas outlet discharge is directly entered exhausting scrubber system, obtains pernicious gas
Processing, protects bad border and the health of people.
Wherein, the absorption tower is respectively the first absorption tower, second absorption tower, third absorption tower.
Wherein, the first absorption tower series connection second absorption tower, second absorption tower series connection third absorption tower.
Wherein, collecting tank liquid level is divided into 3 parts by the partition.
Wherein, the absorption tower, collecting tank material be stainless steel.
Using secondary scheme, stainless steel will not generate burn into spot corrosion, corrosion or abrasion, have it is corrosion-resistant, enhancing intensity,
Deformation of steel is not easily broken and environmental-protecting performance.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. using this scheme, yellow phosphorus steam is entered in collecting tank by air inlet, due to being provided with partition in collecting tank,
And by the water level control of cooling water more than the lower edge of partition, so yellow phosphorus steam can only connect from mutually flowing between absorption tower
Steam come out from absorption tower and enter gas outlet, since limited valve being arranged at the top of gas outlet, under the action of pressure limiting valve gravity
Yellow phosphorus steam can not rush gas outlet, when yellow phosphorus steam is enough in device, increase pressure in device, when what gas generated pushes away
When power is greater than the gravity of pressure limiting valve, pressure limiting valve, which is boosted at this moment gas, can go out gas outlet, simultaneously because inside device
Yellow phosphorus steam releases a part, and pressure reduces in device, and component increases the pressure in pressure limiting valve falling device again.Interval in this way
Property discharge yellow phosphorus steam purpose be that residence time is longer in the device in order to make yellow phosphorus steam, so as to more fully with suction
It receives the cooling water that top of tower spray head sprays to be sufficiently mixed, improves the rate of recovery of yellow phosphorus.
2. the shape on absorption tower is reciprocal folding, so yellow phosphorus steam constantly changes the direction of motion in absorption tower, make to flow
The cooling water that dynamic speed becomes that in this way yellow phosphorus steam can very slowly sprayed with the spray head at the top of absorption tower is sufficiently mixed,
Reach the higher yellow phosphorus rate of recovery.
3. making the impurity in collecting tank that can slide to slag notch, it is convenient to clean.
4. the gas of device gas outlet discharge is directly entered exhausting scrubber system, pernicious gas is handled, protected bad
The health in border and people.
5. stainless steel will not generate burn into spot corrosion, corrosion or abrasion, there is corrosion-resistant, enhancing intensity, deformation of steel to be not easy
Rupture and environmental-protecting performance.
