Abstract
The utility model relates to an explosion-proof lower-mounted water seal device for washing yellow phosphorus tail gases, which is characterized in that the explosion-proof lower-mounted water seal device comprises a washing tower, wherein the washing tower comprises a gas inlet, a gas outlet and a spray nozzle; and an lower opening of the washing tower is arranged in a water tank, and the water level in the water tank is higher than the lower opening of the washing tower. The active effect of the utility model reside in that: the yellow phosphorus tail gases are isolated to air by water, and safety demands are achieved; and even if little air is leaked into the tower, and explosion occurs, the energy of a shock wave is transmitted to water, thereby effectively the tower body and equipment therein.
Description
Technical field
The utility model relates to a kind of fuel gas washing safety device.
Background technology
In the phosphorus production process, one ton of yellow phosphorus of every production can by-product 2500-3000m
3The tail gas from electric furnace of (mark attitude), the CO content in tail gas reaches 87%-92%, and total sulfur 0.8-8g/ m is separately arranged
3, total phosphorus 0.5-1.5g/ m
3, and the raw material dust etc., CO is rich in abundant calorific value, and its calorific capacity is 2500-2700KCa/ m
3It is good thermal source.
In order to utilize the calorific value of yellow phosphoric tail gas, after it can being carried out cleaning dust as fuel gas, then add alkali lye neutralization, the use of burning at last.
Because the burning-point of yellow phosphorus is 35 ℃, so 30 ℃ of spontaneous combustions of can catching fire in humid air are must be isolated with air in the processing procedure of yellow phosphorus.
Summary of the invention
The purpose of this utility model is to provide the deficiency that the explosion-proof underlying water seal of a kind of yellow phosphoric tail gas washing fills to make up prior art.
The utility model is to realize that the technical scheme that purpose adopts is: the explosion-proof underlying water seal arrangement of yellow phosphoric tail gas washing, and it is characterized in that: comprise scrubbing tower, scrubbing tower has air inlet, gas outlet and mouth spray; The end opening of scrubbing tower is placed in tank, and the water level in tank is higher than the under shed of scrubbing tower.
Good effect of the present utility model is: makes water that yellow phosphoric tail gas and air is isolated, reached safety requirements, and; even a small amount of air leak is advanced tower body; produced blast, the energy of its shock wave also can be delivered to water, thus effectively protected tower body with and interior equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment:
Yellow phosphoric tail gas enters in scrubbing tower 2 from air inlet 1, and the liquid of mouth spray 3 ejections in it washs gas, then yellow phosphoric tail gas 4 effusions from the gas outlet.
The opening 5 of scrubbing tower 2 lower ends is placed in tank 6, makes this tower body inside be in sealing state.
If reveal because tower body has part, air enters, will with tail gas in phosphorus reaction, produce combustion explosion, the meeting of its blast makes the water generates distortion, thereby release of pressure has reached the purpose of protection equipment.
