Description
Technical Field
The utility model relates to a yellow phosphorus tail gas processing technology field, in particular to yellow phosphorus tail gas power generation facility burning tail gas processing apparatus.
Background
The phosphorus chemical industry is an important pillar industry in provinces of cloud, noble, sichuan and the like. Theoretically, the byproduct of over 85 percent of carbon monoxide gas is 2500-3000m < 3 > when one ton of yellow phosphorus is produced, and the yellow phosphorus is an indispensible secondary resource. At present, in China, phosphorus ore, coke and silica are mixed according to a certain proportion by adopting an electric furnace method for producing yellow phosphorus, the mixture is heated and melted, phosphorus steam generated by reaction enters a condensation tower along with furnace gas, the phosphorus steam is condensed by water, phosphorus and fluorine in the furnace gas are condensed and enter a phosphorus receiving tank, the residual furnace gas is called phosphorus furnace tail gas, the main component of the tail gas is CO, the direct emission of the yellow phosphorus tail gas has strong pollution to the environment, and the yellow phosphorus tail gas can be emitted only by retreatment.
The existing yellow phosphorus tail gas is usually treated by synthesizing sodium formate with the yellow phosphorus tail gas to produce formic acid. Formic acid is one of basic organic chemical raw materials, and is widely used in the industries of pesticides, leather, textiles, medicines, rubber and the like. Meanwhile, the technical threshold for synthesizing sodium formate from yellow phosphorus tail gas to produce formic acid is low, and a large amount of enterprises invest to construct the device, so that China basically monopolizes the global formic acid market. However, the formic acid market is small, the yield of the yellow phosphorus tail gas is too high, for example, in 2022, the yield of formic acid in luci chemical industry is 40 ten thousand tons, which is the largest global formic acid supplier, (one ton of formic acid needs about 702 cubic meters of yellow phosphorus tail gas, even if the formic acid is produced by the yellow phosphorus tail gas, only 7 billion cubic meters are needed), and the yield of the yellow phosphorus tail gas is large, so other ways must be used to fully utilize the yellow phosphorus tail gas.
As the heat value in the yellow phosphorus tail gas is higher and can reach 11700KJ/m < 3 >, the yellow phosphorus tail gas is utilized to generate electricity to replace the traditional fire coal at the present stage, thereby relieving the shortage of electric power resources and realizing the comprehensive utilization of the resources. The yellow phosphorus tail gas is used for power generation and mainly comprises two stages of tail gas purification and waste heat power generation, and the yellow phosphorus tail gas contains more acidic substances which can corrode a boiler, so that the yellow phosphorus tail gas needs to be purified to prolong the service life of the boiler, the purified yellow phosphorus tail gas is introduced into a gas holder, and then is conveyed into a power station through a booster fan to be combusted and generated by a generator set.
For example in the patent document of publication No. CN215939541U, a yellow phosphorus tail gas recovery and purification tower for power generation is disclosed, tail gas lets in the purification frame through the air inlet, the solenoid valve is used for controlling the speed that tail gas lets in the purification frame, the shower nozzle can flow through the treatment fluid from the water tank through the second pipeline when letting in tail gas, the treatment fluid circulates and starts the high-pressure pump simultaneously, the high-pressure pump makes the treatment fluid diffusion through air cock spun high-pressure gas, conveniently mix with the tail gas that gets into, start first motor simultaneously, first motor can drive the pivot and rotate, the pivot rotates and can drive the stirring leaf and rotate simultaneously, the stirring leaf rotates and makes the mixture of treatment fluid and tail gas more complete.
In the scheme, the yellow phosphorus tail gas filled into the purification frame is purified through the spray head, the purified gas can be directly discharged into the drying chamber to be dried, the dried tail gas enters the generator set to be combusted for power generation, and the problem of environmental pollution caused by direct discharge of the tail gas is solved; secondly, as the treatment liquid is directly introduced into the spray head from the water tank for mixed spraying, but the concentration of the treatment liquid is different when tail gas with different concentrations is treated, and the use of the treatment liquid with the original concentration can reduce the purification effect of the tail gas; owing to set up the stirring leaf, when the stirring leaf rotated, can produce centrifugal force, the air current can be stirred around the stirring leaf, and the tail gas that is located the stirring leaf top can move the lower part of stirring leaf for the mixed degree of treatment fluid and tail gas is lower, has reduced the purifying effect to tail gas.
