Technical Field
The invention relates to the technical field of yellow phosphorus tail gas treatment, in particular to an integrated incineration device capable of treating yellow phosphorus tail gas without pollution and recovering energy.
Background
As the yellow phosphorus tail gas contains a plurality of polluting corrosive gases of sulfur, phosphorus and fluoride, the gas treatment and utilization are difficult. At present, the yellow phosphorus tail gas is pretreated by adopting a mode of pressure swing adsorption, water washing and alkali washing and then is utilized. The problems of the two methods exist at present: 1. the pressure swing adsorption mode is difficult to maintain in industrial production due to the overhigh investment and operation cost. 2. The pretreatment mode of water washing and alkali washing has the problems of low pollutant removal efficiency, corrosion of subsequent energy recovery equipment, secondary water pollution and the like.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and aims to provide an incineration device which can solve the problems of low treatment efficiency and high operation cost of the existing yellow phosphorus tail gas, can recover energy while treating the yellow phosphorus tail gas, and can reduce the operation cost.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
an integrated incineration device capable of carrying out pollution-free treatment on yellow phosphorus tail gas and recycling energy comprises a device body, wherein the device body comprises a first combustion tower and a second combustion tower which are communicated with each other; a fluidizer is arranged on the bottom side of the first combustion tower, and a first ejector positioned on the upper side of the fluidizer is arranged on the outer wall of the first combustion tower; a second ejector is arranged on the outer wall of the first combustion tower on the upper side of the first ejector; the second combustion tower is communicated with the tail gas absorption tower.
Further, the tail gas absorption tower is transversely arranged.
Further, the first injector and the second injector are arranged oppositely on the outer wall of the first combustion tower.
Compared with the prior art, the invention has the following beneficial effects:
the invention sprays yellow phosphorus tail gas and pollutant gases such as sulfur, phosphorus, fluoride and the like into the first combustion tower through the first ejector, and sprays powdery calcium carbonate into the first combustion tower through the second ejector, so that the yellow phosphorus tail gas and calcium carbonate powder carry out combustion reaction in the first combustion tower to form harmless solid products such as calcium sulfate, calcium phosphate, calcium fluoride and the like, and the solid products are recycled as building material additives. In order to fully promote the combustion reaction, the combustion reaction is carried out by two communicated combustion towers, and the waste heat recovery is carried out on the tail gas generated by combustion by using a tail gas absorption tower. The fluidization device at the bottom side of the first combustion tower blows the yellow phosphorus tail gas and the calcium carbonate powder, and also can play a role in promoting the combustion reaction, and simultaneously can blow the solid mixture formed by combustion to the tail gas absorption tower through air flow to be collected.

Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in figure 1, the integrated incineration device capable of carrying out pollution-free treatment on the yellow phosphorus tail gas and recycling energy comprises a device body, wherein the device body comprises a first combustion tower 4 and a second combustion tower 5, the upper parts of which are communicated with each other; a fluidizer 3 is arranged at the bottom side of the first combustion tower 4, and a first ejector 1 positioned at the upper side of the fluidizer 3 is arranged on the outer wall of the first combustion tower 4; a second ejector 2 is arranged on the outer wall of the first combustion tower 4 on the upper side of the first ejector 1; the second combustion tower 5 is communicated with a tail gas absorption tower 6; the first injector 1 and the second injector 2 are arranged oppositely on the outer wall of the first combustion tower 4.
When the invention is used, the first combustion tower 4 and the second combustion tower 5 are selected from combustion towers which can increase the combustion temperature to 9001100 ℃. After being dried from a yellow phosphorus raw material workshop, the yellow phosphorus tail gas and pollutant gases such as sulfur, phosphorus, fluoride and the like are sent to a first combustion tower 5 through a first ejector 1, and powdery calcium carbonate is sent to a first combustion tower 4 through a second ejector 2 and is subjected to reaction combustion in the first combustion tower 4. Under the action of the fluidizer, the calcium carbonate powder floats in the first combustion tower 4 and is fully mixed with the yellow phosphorus tail gas and other pollutant gases to promote the combustion reaction, and the combustion effect is improved through the second combustion tower 5 connected with the first combustion tower 4. The gas is incinerated to 9001100 ℃, changing the pollutant gas to a highly reactive gas, promoting the combustion reaction. Thereby removing harmful substances, forming harmless solid products such as calcium sulfate, calcium phosphate, calcium fluoride and the like, and recycling the solid products as building material additives. The high-temperature flue gas and the powder product after the reaction enter a tail gas absorption tower 6 for energy recovery. The tail gas absorption tower 6 is transversely arranged, so that products generated by combustion can be conveniently introduced into the tail gas absorption tower 6 along with airflow, and the products can be conveniently collected.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
