Abstract
The utility model relates to a three-stage water washing tower for yellow phosphorus tail gas, and is characterized by comprising three stages of series tower bodies, wherein the tower bodies are provided with air inlets and air outlets; the first-stage tower body and the second-stage tower body are provided with water spraying ports, and spoilers are arranged in the tower bodies; and absorption carriers are arranged in the three stages of tower bodies. The three-stage water washing tower, provided by the utility model, has the advantages that: the tail gas is sprayed by the water, so that liquid phosphorous, sulfur and dust impurities in the tail gas are sprayed by the water and settled. The washed dust is 0.0036-0.0054 kg/m<3>. On the one hand, the cleanliness of the tail gas is improved, and a sequent combustion process is ensured to preform successfully. On the other hand, a phosphorus product is recovered.
Description
Technical field
The utility model relates to a kind of gas cleaning unit.
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 the tail gas reaches 87%-92%, and other has total sulfur 0.8-8g/ m
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, it can be burnt as fuel gas, owing to wherein contain impurity, impurity must be removed the burning operation of guarantee back and carry out normally.
Summary of the invention
The purpose of this utility model provides three grades of water wash column of a kind of yellow phosphoric tail gas to remedy the deficiency of prior art.
The utility model for realizing the technical scheme that purpose adopts is: three grades of water wash column of yellow phosphoric tail gas is characterized in that: be provided with the tower body of three grades of series connection, tower body all has air inlet and gas outlet; The water mouth spray is arranged on the firsts and seconds tower body, spoiler is arranged in the tower body; In three grades of tower bodies absorption carrier is arranged.
Optimize, absorption carrier is hollow round table.
Good effect of the present utility model is: water spray tail gas makes liquid phosphorus in the tail gas, sulphur, dust impurity by sprayed sedimentation by water.Dust is 0.0036-0.0054Kg/ m after the washing
3Improve so on the one hand the cleanliness factor of tail gas, guaranteed carrying out smoothly of subsequent combustion operation.On the other hand, can reclaim phosphorus product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of hollow round table.
The specific embodiment
Embodiment:
Yellow phosphoric tail gas enters in the one-level tower body 2 from air inlet 1, and the water of water mouth spray 3 ejections on it carries out cleaning dust to gas, and spoiler 8 plays the effect that increases gas-water contact area.Then yellow phosphoric tail gas 4 enters secondary tower body 5 from the gas outlet, carries out entering three grades of towers 6 behind the repeated washing in secondary tower body 5.
Hollow round table 7 in three grades of tower bodies 6 is spreading at random, and gas is in process of osmosis, and its impurity also can be adsorbed by hollow round table 7.At last, qualified yellow phosphoric tail gas is sent to next procedure from three grades of tower bodies.
In one-level tower body 2 and secondary tower body 5 spray washing processes, phosphorus can with falling under water in the feeder 9, can be recycled.
