Description

TECHNICAL FIELD

[0029] The present application will be described in detail below with reference to the drawings and optional embodiments.

[0030] Figure 1 is a schematic diagram of an equipment for treating waste gas by ion exchange resin according to an embodiment of the present application, as Figure 1 As shown in the figure, the present application discloses an equipment for treating waste gas by ion exchange resin 10, which comprises a waste gas treatment unit 20, a shower tank 300, a first pneumatic stirrer 310, a first medicine storage tank 411, a second medicine storage tank 412, a cation exchange column 510 and a tap water source 530, wherein the waste gas treatment unit 20 comprises a waste gas treatment main body 21, and a gas inlet 22, a gas outlet 23, a first shower liquid inlet 24, a second shower liquid inlet 25 and a waste gas treatment drainage 26 arranged on the waste gas treatment main body 21.

[0031] The shower tank 300 is communicated with the first shower liquid inlet 24 and the second shower liquid inlet 25 through a first liquid pump 710, a first valve 801 is arranged on the first shower liquid inlet 24, a second valve 802 is arranged on the second shower liquid inlet 25, and the first pneumatic stirrer 310 is arranged in the shower tank 300 for stirring the shower in the shower tank 300.

[0032] The liquid outlet of the first medicine storage tank 411 is communicated with the liquid inlet of the shower tank 300 through a second liquid pump 720, and the first medicine storage tank 411 is used for storing sodium chlorite; the liquid outlet of the second medicine storage tank 412 is communicated with the liquid inlet of the shower tank 300 through a third liquid pump 730 and a third valve 803, and the second medicine storage tank 412 is used for storing sodium hydroxide.

[0033] The outlet of the cation exchange column 510 is communicated with the inlet of the shower tank 300 through the fourth valve 804, the waste gas treatment drainage 26 is connected with the inlet of the cation exchange column 510 through the fourth liquid pump 740 and the fifth valve 805, and the tap water source 530 is connected with the inlet of the cation exchange column 510 through the sixth valve 806.

[0034] The shower liquid is used to regenerate the resin filter layer in the waste gas treatment unit 20, that is, the resin filter layer can be regenerated by spraying the shower liquid on the resin filter layer in the waste gas treatment unit 20.

[0035] For example, the flow rates of the second liquid pump 720 and the third liquid pump 730 are adjusted to be 2.0 m3 / h, the fourth valve 804 and the sixth valve 806 are opened, until the water level in the shower tank 300 rises to the highest control point, then the fourth valve 804 and the sixth valve 806 are closed, the second liquid pump 720 is opened for 3 minutes and then closed, and the third liquid pump 730 and the third valve 803 are opened for 5 minutes and then closed; then the first pneumatic agitator 310 is started to run for 10 minutes, so as to complete the configuration of the shower liquid.

[0036] Compared with the existing waste gas treatment device 10 using ion exchange resin, the first pneumatic agitator 310, the first medicine storage tank 411 storing sodium chlorite and the second medicine storage tank 412 storing sodium hydroxide are additionally arranged in the shower tank 300. After the shower liquid in the shower tank 300 is used up, the sodium chlorite in the first medicine storage tank 411 and the sodium hydroxide in the second medicine storage tank 412 are directly delivered into the shower tank 300, and then tap water is delivered into the shower tank 300 from the tap water source 530, and the first pneumatic agitator 310 is used to stir in the shower tank 300. In this way, it is not necessary to set a separate configuration tank to configure the shower liquid and then add it into the shower tank 300, so that the operation difficulty is reduced and the use convenience is improved.

[0037] Moreover, the cation exchange column 510 is additionally arranged in the present application. The tap water from the tap water source 530 is hard water, which is first changed into soft water through the cation exchange column 510, that is, the cation exchange column 510 is used to soften the tap water, and then the tap water is delivered into the shower tank 300. The shower liquid configured by the soft water makes the resin filter layer have a higher regeneration efficiency.

[0038] Figure 2 is a schematic view of a waste gas treatment unit according to an embodiment of the present application, as Figure 2As shown, the exhaust treatment unit 20 further comprises a first resin filter layer 211, a second resin filter layer 212, a third resin filter layer 213, a fourth resin filter layer 214, a first spraying structure 221, a second spraying structure 222, a third spraying structure 223 and a fourth spraying structure 224, the first resin filter layer 211, the second resin filter layer 212, the third resin filter layer 213 and the fourth resin filter layer 214 are sequentially arranged from top to bottom in the exhaust treatment main body 21.

[0039] Exhaust gas enters from the gas inlet 22, passes through the first resin filter layer 211, the second resin filter layer 212, the third resin filter layer 213 and the fourth resin filter layer 214 respectively, and is discharged from the gas outlet 23.

[0040] The first spraying structure 221 is located on the first resin filter layer 211, the second spraying structure 222 is located on the second resin filter layer 212, the third spraying structure 223 is located on the third resin filter layer 213, and the fourth spraying structure 224 is located on the fourth resin filter layer 214.

[0041] The first spraying structure 221, the second spraying structure 222 and the first spraying liquid inlet 24 are in communication, and the third spraying structure 223, the fourth spraying structure 224 and the second spraying liquid inlet 25 are in communication.

[0042] Because the exhaust treatment unit 20 is provided with four layers of resin filter layers, namely the first resin filter layer 211, the second resin filter layer 212, the third resin filter layer 213 and the fourth resin filter layer 214, and each layer of resin filter layer is provided with a spraying structure above, namely the first spraying structure 221, the second spraying structure 222, the third spraying structure 223 and the fourth spraying structure 224.

[0043] Therefore, in order to ensure the uniformity of the spraying of the spraying structure, the first valve 801 and the second valve 802 are arranged, when the first valve 801 is opened, the spraying liquid will enter the first spraying structure 221 and the second spraying structure 222 from the first spraying liquid inlet 24, and be sprayed on the upper two layers of the first resin filter layer 211 and the second resin filter layer 212, when the second valve 802 is opened, the spraying liquid will enter the third spraying structure 223 and the fourth spraying structure 224 from the second spraying liquid inlet 25, and be sprayed on the lower two layers of the third resin filter layer 213 and the fourth resin filter layer 214, so as to ensure that the spraying liquid is uniformly sprayed on the first resin filter layer 211, the second resin filter layer 212, the third resin filter layer 213 and the fourth resin filter layer 214.

[0044] For example, the first liquid pump 710 and the first valve 801 are opened, and when the liquid level in the shower tank 300 drops to the first control point, the first valve 801 is closed; the second valve 802 is opened, and when the liquid level in the shower tank 300 drops to the lowest control point, the second valve 802 is closed, thereby completing the regeneration of the first resin filter layer 211, the second resin filter layer 212, the third resin filter layer 213, and the fourth resin filter layer 214.

[0045] Referring to Figure 1 The device 10 for treating waste gas by using ion exchange resin further comprises an anion exchange column 520, and a liquid outlet of the cation exchange column 510 is communicated with a liquid inlet of the anion exchange column 520 through a seventh valve 807, and a liquid outlet of the anion exchange column 520 is communicated with the shower tank 300 through an eighth valve 808.

[0046] The communication between the cation exchange column 510 and the anion exchange column 520 can adjust the PH value of the circulating water, and the capacity of the anion exchange column 520 is increased.

[0047] In addition, the liquid outlet of the cation exchange column 510 is connected with a sewer through an eighteenth valve 818, and the waste gas treatment drainage 26 is connected with the sewer through a fourth liquid pump 740 and a nineteenth valve 819, so that the liquid in the cation exchange column 510 can be directly discharged into the sewer, and the liquid in the waste gas treatment unit 20 can be directly discharged into the sewer.

[0048] The device 10 for treating waste gas by using ion exchange resin further comprises a waste liquid pool 540, and a liquid outlet of the anion exchange column 520 is communicated with a liquid inlet of the waste liquid pool 540 through a ninth valve 809, and a liquid outlet of the waste liquid pool 540 is connected with a drainage pipeline through a fifth liquid pump 750.

[0049] The excess liquid in the anion exchange column 520 can be first stored in the waste liquid pool 540, and then discharged into a waste water treatment station of a factory through the drainage pipeline for comprehensive treatment.

[0050] After running for a period of time, the cation exchange column 510 needs to be regenerated, and the third storage tank 413, the first regeneration liquid tank 421, and the second pneumatic agitator 320 are added, the third storage tank 413 is used for storing hydrogen chloride with a higher concentration, and the first regeneration liquid tank 421 is used for storing hydrogen chloride regeneration liquid with a lower concentration.

[0051] Specifically, the device 10 for treating waste gas by ion exchange resin further comprises a third storage tank 413, a first regeneration liquid tank 421, and a second pneumatic agitator 320. The tap water source 530 is connected to the liquid inlet of the first regeneration liquid tank 421 through the tenth valve 810, and the first regeneration liquid tank 421 is used to store hydrogen chloride regeneration liquid. The liquid outlet of the third storage tank 413 is connected to the liquid inlet of the first regeneration liquid tank 421 through the sixth liquid pump 760, and the third storage tank 413 is used to store hydrogen chloride. The second pneumatic agitator 320 is arranged in the first regeneration liquid tank 421 and used to agitate the hydrogen chloride regeneration liquid in the first regeneration liquid tank 421.

[0052] The liquid outlet of the first regeneration liquid tank 421 is connected to the liquid inlet of the cation exchange column 510 through the seventh liquid pump 770. In this way, one more cation exchange column 510 does not need to be arranged as a backup, thereby reducing the cost of the device 10 for treating waste gas by ion exchange resin.

[0053] For example, when the water outlet of the cation exchange column 510 has a pH of 5, regeneration is performed. First, the seventh liquid pump 770 and the eighteenth valve 818 are opened, the eighteenth valve 818 is controlled to have a flow rate of 1 m3 / h, and when the liquid level in the first regeneration liquid tank 421 is lowered to the lowest point, the seventh liquid pump 770 is closed. After the sixth valve 806 is opened for three minutes, the sixth valve 806 and the eighteenth valve 818 are automatically closed, and the regeneration of the cation exchange column 510 is completed.

[0054] For example, the tenth valve 810 is opened, and when the liquid level in the first regeneration liquid tank 421 rises to the set position, the tenth valve 810 is closed. Then, the sixth liquid pump 760 is opened for 10 minutes and then closed. Then, the second pneumatic agitator 320 is opened, and 10 minutes later, the second pneumatic agitator 320 is automatically stopped, and the configuration in the first regeneration liquid tank 421 is completed.

[0055] After running for a period of time, the anion exchange column 520 also needs to be regenerated. Specifically, the device 10 for treating waste gas by ion exchange resin further comprises a second regeneration liquid tank 422 and a third pneumatic agitator 330. The tap water source 530 is connected to the liquid inlet of the second regeneration liquid tank 422 through the eleventh valve 811. The liquid outlet of the second storage tank 412 is connected to the liquid inlet of the second regeneration liquid tank 422 through the third liquid pump 730 and the twelfth valve 812. The second regeneration liquid tank 422 is used to store sodium hydroxide regeneration liquid. The second pneumatic agitator 320 is arranged in the second regeneration liquid tank 422 and used to agitate the sodium hydroxide regeneration liquid in the second regeneration liquid tank 422.

[0056] The liquid outlet of the second regeneration liquid tank 422 is communicated with the liquid inlet of the anion exchange column 520 through the thirteenth valve 813 and the eighth liquid pump 780, and the tap water source 530 is communicated with the liquid inlet of the anion exchange column 520 through the fourteenth valve 814.

[0057] The device 10 for treating waste gas by ion exchange resin further comprises a reuse liquid tank 550, the liquid outlet of the anion exchange column 520 is communicated with the liquid inlet of the reuse liquid tank 550 through the fifteenth valve 815, and the liquid outlet of the reuse liquid tank 550 is communicated with the liquid inlet of the anion exchange column 520 through the sixteenth valve 816 and the eighth liquid pump 780.

[0058] In this way, one more anion exchange column 520 does not need to be set as a backup, thereby reducing the cost of the device 10 for treating waste gas by ion exchange resin.

[0059] For example, when the PH of the water outlet of the anion exchange column 520 is 5, the anion exchange column 520 starts regeneration; the eighth liquid pump 780, the sixteenth valve 816 and the ninth valve 809 are opened, the liquid in the reuse liquid tank 550 is discharged into the anion exchange column 520, and at the same time, the liquid in the anion exchange column 520 is discharged into the waste liquid pool 540, when the liquid level of the reuse liquid tank 550 drops to the lowest point, the sixteenth valve 816 and the ninth valve 809 are closed.

[0060] The thirteenth valve 813 and the fifteenth valve 815 are opened, the liquid in the second regeneration liquid tank 422 is input into the anion exchange column 520, and at the same time, the liquid in the anion exchange column 520 is discharged into the reuse liquid tank 550, when the liquid level in the second regeneration liquid tank 422 drops to the lowest point, the eighth liquid pump 780, the thirteenth valve 813 and the fifteenth valve 815 are closed.

[0061] The fourteenth valve 814 and the ninth valve 809 are opened, and after three minutes, the fourteenth valve 814 and the ninth valve 809 are closed, tap water is added into the anion exchange column 520, and at the same time, the liquid in the anion exchange column 520 is discharged into the waste liquid pool 540, thereby completing the regeneration of the anion exchange column 520.

[0062] For example, the eleventh valve 811 is opened, and when the liquid level in the second regeneration liquid tank 422 rises to the set position, the eleventh valve 811 is closed, that is, tap water is added into the second regeneration liquid tank 422. The third liquid pump 730 and the twelfth valve 812 are opened, and after 10 minutes, the third liquid pump 730 and the twelfth valve 812 are closed. Then the third pneumatic stirrer 330 is started, and after 10 minutes, it is automatically stopped, thereby completing the configuration in the second regeneration liquid tank 422.

[0063] After running for a period of time, the shower liquid in the shower tank 300 needs to be replaced, so the application also sets the first liquid pump 710 and the seventeenth valve 817, and the liquid outlet of the shower tank 300 is connected with the drain pipe through the first liquid pump 710 and the seventeenth valve 817.

[0064] For example, directly open the pump first liquid pump 710 and the seventeenth valve 817, when the liquid level of the shower tank 300 drops to the lowest point, close the pump first liquid pump 710 and the seventeenth valve 817, to drain the liquid in the shower tank 300, and then reconfigure the shower liquid, which will not be repeated here.

[0065] Moreover, the tap water source 530 of the application can also be connected with the liquid inlet of the shower tank 300 through the twentieth valve 820, and after a long time of running, the circulating water will be lost, so the twentieth valve 820 is added to supplement the lost water in the shower tank 300.

[0066] It should be noted that the inventive concept of the application can form a very large number of embodiments, but the length of the application file is limited, and it is not possible to list them one by one, so the above described embodiments or technical features can be combined to form new embodiments without conflict, and the combination of each embodiment or technical feature will enhance the original technical effect.

[0067] The above is a further detailed description of the application in combination with specific optional embodiments, and cannot be considered as limiting the specific implementation of the application to these descriptions. For ordinary skilled persons in the technical field to which the application belongs, without departing from the concept of the application, a number of simple deductions or substitutions can be made, which should be considered as falling within the protection scope of the application.
