The invention discloses a conveying device capable of being used for a yellow phosphorus tail gas purification system. The device comprises a yellow phosphorus electric furnace, wherein a differentialpressure transmitter is arranged on the yellow phosphorus electric furnace, the yellow phosphorus electric furnace is communicated with a main water seal pipeline, an air inlet and an air outlet arerespectively formed in the main water seal pipeline, the main water seal is communicated with a first water washing structure through a pipeline, the air outlet is communicated with a first water washing structure through a pipeline, the first water washing structure is communicated with a first gas-water separation assembly through a pipeline, and the first gas-water separation assembly is communicated with a second water washing structure through a pipeline. The differential pressure transmitter is arranged at the air outlet of the yellow phosphorus electric furnace, the yellow phosphorus tail gas purification system is used for controlling the pressure in the yellow phosphorus electric furnace and improving stability of the pressure in the yellow phosphorus electric furnace through thePLC control system by adjusting the running rotating speed of the water ring vacuum pump and adjusting the extraction amount of the yellow phosphorus tail gas in unit time, and the purification quality of the yellow phosphorus tail gas is improved through mutual cooperation of water washing and alkali washing.
Description
technical field [0001] The invention relates to a conveying device, more specifically, the present invention mainly relates to a conveying device which can be used in a yellow phosphorus tail gas purification system. Background technique [0002] During the yellow phosphorus manufacturing process, yellow phosphorus tail gas containing 80-90% CO is produced as a by-product; for many years, the comprehensive utilization technology has developed to direct fuel - yellow phosphorus tail gas boiler, or as raw material - production of sodium formate, etc. The composition and properties of yellow phosphorus tail gas are complex , the purification treatment is difficult, difficult to process and recycle, and it is discharged by combustion, which not only causes waste of sulfur and carbon resources in the gas, but also seriously pollutes the atmospheric environment. Due to the unstable reaction in the yellow phosphorus electric furnace, the amount of tail gas generated per unit time ma...
