[0024] Please refer to Figures 1-4, an embodiment of the present utility model provides a technical solution: a nitroaromatic condensing collector, including a condensing tank 1, a top plate 2 is provided at the top of the condensing tank 1, a mounting plate 3 is provided at the lower end of the top plate 2, a condensing column 4 is fixedly connected to the lower end of the mounting plate 3, a condensing pipe 5 is provided on the outer surface of the condensing column 4, a water inlet 501 and a water outlet 502 are provided at the top end of the condensing pipe 5, a mounting block 6 is provided inside the condensing tank 1, a cover plate 7 is fixedly connected inside the mounting block 6, a filter screen 8 and an activated carbon filter element 9 are provided at the bottom of the condensing tank 1. By providing the mounting plate 3, the condensing column 4, and the condensing pipe 5, it is beneficial to condense nitroaromatic gas within the largest range, reduce the situation of incomplete condensation, avoid gas waste. By providing the mounting block 6 and the cover plate 7, it is beneficial to prevent the condensed nitroaromatic liquid from falling into the trachea 16 and avoid pollution of the trachea 16. By providing the filter screen 8 and the activated carbon filter element 9, it is beneficial to remove impurities from the nitroaromatic liquid and adsorb odors.

[0025] A water outlet pipe 10 is fixedly connected to the bottom of the condensing tank 1, a valve 11 is provided inside the water outlet pipe 10, a temperature detector 12 is provided on the outer surface of the condensing tank 1, a mounting frame 13 is provided at the bottom of the condensing tank 1, a reaction kettle 14 is provided on the side of the condensing tank 1, a base 15 is provided at the bottom of the reaction kettle 14, a trachea 16 is provided at the top end of the reaction kettle 14, and an air outlet 1601 is provided at one end of the trachea 16. By providing the temperature detector 12, it is beneficial to detect the temperature suitable for condensing nitroaromatic gas and extract the nitroaromatic liquid with the highest purity. By providing the reaction kettle 14 and the trachea 16, it helps the nitroaromatic gas to directly enter the condensing tank 1 for condensation.

[0026] The upper half of the condensing tank 1 is a cylinder, and the lower half is a sphere. The condensing pipe 5 passes through the inside of the condensing tank 1 and surrounds the outer surface of the condensing column 4. The condensing column 4 is installed inside the condensing tank 1 and is made of metal. The condensing column 4 is located above the cover plate 7, the cover plate 7 is located above the air outlet 1601, one end of the trachea 16 passes through the condensing tank 1 and is located above the cover plate 7, and the water outlet pipe 10 is located inside the mounting frame 13.

[0027] Working principle: For this nitroaromatic condenser, during the synthesis of compounds in the reaction kettle 14, various intermediates such as nitrosobenzene, hydroxylamine, and azoxybenzene are generated. The gaseous nitroaromatic hydrocarbons will directly enter the condensation tank 1 through the gas pipe 16 for condensation, avoiding waste and even air pollution caused by gas leakage. The condensate flows in from the water inlet 501 of the condenser tube 5 and flows out from the water outlet 502. During the flow of the condensate, the temperature inside the condenser tube 5 decreases, and the condenser tube 5 drives the temperature of the condensation column 4 to decrease. Multiple condensation columns 4 are arranged on the mounting plate 3, making the temperature in the condensation tank 1 decrease faster and in a wider range, being able to condense the nitroaromatic hydrocarbon gas into liquid to the greatest extent, avoiding incomplete condensation and preventing the pollution of the environment by the excess gas. Through the temperature detector 12, it can be observed that the temperature inside the condensation tank 1 reaches a suitable temperature for condensing the nitroaromatic hydrocarbon gas into liquid. The gaseous nitroaromatic hydrocarbons move upward through the gas pipe 16 and come into contact with the condensation column 4, and the gas condenses into liquid and hangs on the condensation column 4. When the amount of nitroaromatic hydrocarbon gas increases, the continuous low temperature will also make the condensed liquid increase. At this time, the nitroaromatic hydrocarbon liquid drips downward. A cover plate 7 is installed inside the condensation tank 1, and the cover plate 7 is set above the air outlet 1601, which can ensure the large-scale condensation of the nitroaromatic hydrocarbon gas inside the condensation tank 1 and prevent the dropped liquid nitroaromatic hydrocarbons from entering the inside of the gas pipe 16, effectively preventing the pollution of the gas pipe 16 and being unfavorable to the production of nitroaromatic hydrocarbon gas. The liquid passes through the filter screen 8 and the activated carbon filter element 9 and flows out from the water outlet pipe 10. The setting of the activated carbon filter element 9 is beneficial to removing the impurities of the nitroaromatic hydrocarbon liquid and adsorbing the peculiar smell.

However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can also be made without departing from the purpose of the present invention.
