Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater nitrobenzene treatment technology, specifically, to a treatment device for emergency removal of nitrobenzene in the event of a sudden environmental incident. Background Technology
[0002] Nitrobenzene, with the molecular formula C5H6NO2, a relative molecular weight of 123, a relative density (water=1) of 1.20, a melting point of 5.7℃, and a boiling point of 210.9℃, exhibits extremely high stability in water. Due to its density being greater than water, it sinks to the bottom of water bodies and remains unchanged for a long time. Furthermore, because of its certain solubility in water, the resulting water pollution can persist for a considerable period. Industrial wastewater often contains nitrobenzene, and direct discharge will pollute water sources. Treatment is very complicated and requires highly specialized equipment for removal.
[0003] Currently, nitrobenzene is only detected after it has been discharged, lacking a detection process before discharge. Once discharged into a river, it is difficult to clean up. Moreover, once discharged into the river, the nitrobenzene needs to be pumped out and filtered. In the past, only one filtration method was used, which easily led to incomplete removal and made it impossible to carry out multiple filtration treatments. Therefore, this application proposes an emergency treatment device for the removal of nitrobenzene in sudden environmental incidents to solve this problem.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0023] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:
[0024] Please see Figure 1-4 According to an embodiment of the present invention, an emergency treatment device for removing nitrobenzene in the event of a sudden environmental incident includes: a treatment tank 1, an internal detection chamber 101, a filter chamber 106 on one side of the detection chamber 101, a reaction chamber 107 on one side of the detection chamber 101, a stirring blade 108 inside the reaction chamber 107, and a filter element 110 at the bottom of the reaction chamber 107; a control box 2 installed outside the treatment tank 1, with a water quality detector 201 fixedly installed inside the control box 2; a filter drawer 3 installed inside the filter chamber 106; and a reagent cylinder 302 installed above the reaction chamber 107. The present invention uses the water quality detector 201 for emergency detection and the activated carbon filter plate 301 and filter element 110 to filter nitrobenzene, making it suitable for emergency treatment of sudden nitrobenzene incidents.
[0025] According to the above-described scheme of this utility model, an inlet valve 102 is installed on the upper side of one side of the detection chamber 101, and a drain valve 103 is installed on the lower side of one side of the detection chamber 101. The probe of the water quality detector 201 extends into the detection chamber 101. A controller 202 is connected to one side of the water quality detector 201. A lift pump 104 is provided at the bottom of the detection chamber 101. A lift pipe 105 is connected to one side of the lift pump 104. The other end of the lift pipe 105 extends into the filter chamber 106, which facilitates emergency detection to determine whether the water source is polluted.
[0026] According to the above-mentioned solution of this utility model, the bottom of the filter drawer 3 is provided with an activated carbon filter plate 301, the activated carbon filter plate 301 is bolted to the filter drawer 3, and the filter drawer 3 is sleeved with the treatment tank 1 to facilitate the adsorption and filtration of nitrobenzene by activated carbon.
[0027] According to the above-described scheme of this utility model, a metering valve 303 is fixedly installed at the bottom of the reagent cylinder 302. The metering valve 303 is connected to the pipeline of the reaction chamber 107 to facilitate the metered discharge of the reagent, so that it can be mixed and reacted with nitrobenzene. A motor 109 is provided at the top of the reaction chamber 107. The output end of the motor 109 is connected to the stirring blade 108. The motor 109 is bolted to the treatment tank 1. The motor 109 is composed of a geared motor to facilitate mixing and stirring of the reagent. A liquid pump 111 is fixedly installed on the outside of the treatment tank 1. The liquid pump 111 is connected to the valve of the filter element 110 to facilitate reverse osmosis filtration of nitrobenzene.
[0028] In practical use, water contaminated with nitrobenzene is injected into the detection chamber 101 through the inlet valve 102. The detection chamber has an inclined structure. The treated wastewater is tested by the water quality detector 201. If the water passes the test, it is discharged through the drain valve 103. If the water fails the test, the drain valve 103 is closed, and the controller 202 controls the lift pump 104 to pump the unqualified wastewater into the filter chamber 106. The unqualified wastewater is then adsorbed and filtered by the activated carbon filter plate 301 in the filter drawer 3.

The filter element 110 adopts a reverse osmosis membrane with a pore size of 0.0001 microns, which can retain benzene molecules with a diameter of 0.00058 microns. It not only has the effect of water quality detection, but also has the effect of emergency filtration to remove nitrobenzene.
