Description

Technical Field

[0001] The utility model relates to the technical field of gas purification devices, in particular to a sulfide-containing gas purification device. Background Art

[0002] Sulfur compounds refer to a class of compounds formed by metals or non-metals with strong positive charge and sulfur. During industrial production, sulfur compound-containing gases will be generated. If such gases are directly discharged, it will not only cause environmental pollution, but also cause harm to human health. At present, sulfur compound-containing gases are mostly purified by activated carbon filtration, but there are sulfur compound-containing gas purification devices that often cause sulfur compound-containing gases to be discharged before they are completely purified. To solve the above problem, a Chinese patent (patent publication number: CN206778137 U) discloses a sulfur compound-containing gas purification device, which adjusts the gap between the first notch and the second notch by the flow rate of the sulfur compound gas, so that the sulfur compound in the device body automatically changes the purification time according to the flow rate. However, the activated carbon layer in the device cannot be replaced. After a certain period of use, the failure of the activated carbon layer will cause the sulfur compound to be discharged into the air, and the gas cannot be detected during discharge, and it is impossible to know whether the sulfur compound is purified. Utility Model Content

[0003] The utility model aims to provide a sulfur compound gas purification device to solve the problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The principle of the basic technical solution: the box first performs preliminary filtration on the sulfur compound gas, and the filter plate is movably connected to the box to realize the replacement or cleaning of the filter plate, and then the gas is introduced into the generating tank for secondary purification. The purified gas is discharged after passing the detection component, and the unpurified gas is returned to the box through the pipeline for secondary filtration.

[0007] The beneficial effects of the basic technical solution are: through the double filtration of the activated carbon layer and the reaction tank, the sulfur-containing compound gas is effectively purified, and it will not be discharged until it passes the inspection of the detection component. The unqualified gas is circulated to the box for filtration again, effectively controlling the risk of sulfur-containing compound gas being discharged into the air without being purified.

[0009] Through the above arrangement, when the filter plate is used for a period of time and the activated carbon on the filter plate becomes ineffective, the filter plate can be taken out for cleaning and covered with new activated carbon, thus saving materials.

[0010] Preferably, the detection assembly comprises a sulfide gas sensor, an alarm and a control panel, the sulfide gas sensor is arranged at the outlet of the second pipeline, and the alarm and the control panel are arranged at the side end of the gas outlet tank.

[0011] Through the above settings, after the purified gas passes the sulfide detector and is qualified, the electronic valve opens to discharge the gas. The unqualified electronic valve will not open, and the gas flows back to the box through the third channel for further evolution. If the electronic valve does not work for a long time, the alarm will sound to remind the operator to check whether the filter plate or the reaction material in the reaction tank needs to be replaced.

[0012] Preferably, the feed port and the discharge port are provided with sealing covers.

[0013] By means of the above arrangement, gas leakage is avoided.

[0014] Preferably, support rods are provided at the lower ends of the box body, the reaction tank and the gas outlet tank, and the bottom of the reaction tank is arc-shaped.

[0015] Through the above arrangement, the bottom of the reaction tank is curved, making it easier to drain the substances in the reaction tank.

Tank 16, the second pipeline 11 is provided with a first one-way valve 12, the gas outlet tank 16 is provided with a sulfide detection component, the detection component includes a sulfide gas sensor 13, an alarm 23 and a control panel 15, the sulfide gas sensor 13 is arranged at the mouth of the second pipeline 11, the alarm 23 is arranged at the upper end of the gas outlet tank 16, and the control panel 15 is arranged at the side end of the gas outlet tank 16. The upper end of the gas outlet tank 16 is provided with a gas outlet 21, and the gas outlet 21 is provided with an electronic valve 14, the liquid level sensor 10, the buzzer 24, the alarm 23, the sulfide sensor and the control panel 15 are electrically connected, the lower end of the gas outlet tank 16 is provided with a third pipeline 17 connected to the box body 3, the end of the third pipeline 17 close to the box body 3 is provided with a second one-way valve 19, the end of the third pipeline 17 close to the gas outlet tank 16 is provided with a second fan 18, and the box body 3, the reaction tank 9 and the lower end of the gas outlet tank 16 are provided with a support rod 20.

[0024] The specific implementation process is as follows:

[0025] First, connect the air inlet pipe 2 to the flue, start the first fan 1, and the sulfur compound gas is sucked into the box 3. The gas first contacts the filter plate 4 in the box 3. The activated carbon on the filter plate 4 can absorb part of the sulfur-containing substances. The gas enters the solution in the reaction tank 9 through the first pipe 6. The reaction tank 9 stores an alkaline solution and a catalyst that reacts with sulfides. The alkaline solution enters the reaction tank 9 through the feed port 7 and is discharged through the discharge port 8 after use. At this time, the gas enters the gas outlet tank 16 through the third pipe 17. After being detected by the sulfur compound sensor, the electronic valve 14 automatically opens to discharge the gas if it meets the emission standards. If the use time is too long or the gas contains sulfur compounds, the gas will be discharged. If there are too many substances and the gas cannot be purified to the standard, the electronic valve 14 will not open. At this time, the second fan 18 will start to transport the gas that has not been purified to the standard to the box 3 through the third pipeline 17 for secondary evolution. This cycle is repeated to ensure that the discharged gas meets the standards. When the electronic valve 14 is not opened for a long time, the alarm 23 will sound to remind the staff to check whether there are too many sulfides accumulated on the activated carbon of the filter plate 4, resulting in failure to purify. At this time, the filter plate 4 can be taken out for cleaning and the activated carbon can be reattached. Secondly, check whether the solution in the reaction tank 9 is invalid. If it is invalid, the corresponding solution and catalyst can be replaced.
