Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a petrochemical tail gas treatment device. Background Art

[0002] Chemical waste gas refers to the toxic and harmful gases discharged by chemical plants during chemical production. The discharged gases often contain many types of pollutants. If the harmful gases are discharged directly, it is easy to pollute the surrounding environment. This requires the gas to be treated before discharge to meet the emission standards. Therefore, the existing petrochemical tail gas treatment equipment has been continuously innovated and developed. Therefore, it can be seen that the current petrochemical tail gas treatment equipment basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN211612175U discloses a spray tank and an adsorption box, wherein the upper end of the spray tank is fixedly connected with a fixed cylinder, a water pipe is rotatably sleeved in the fixed cylinder through a ball bearing, the upper end of the water pipe is fixedly sleeved with a driven gear, the upper end of the spray tank is fixedly connected with a driving motor, the upper end output shaft of the driving motor is fixedly connected with a driving gear meshing with the driven gear, the pipe wall of the water pipe located in the spray tank is connected with a plurality of annular hollow disks through a plurality of uniformly and symmetrically arranged delivery pipes, and the lower end of the annular hollow disk is fixedly connected with a plurality of tilted atomizing nozzles. The utility model can effectively improve the spray range of the spray liquid, ensure the quality of the spray treatment, and expand the spray range of the equipment by setting a plurality of annular hollow disks and a plurality of nozzles, thereby improving the quality of the spray treatment of the equipment.

[0004] However, when the spraying mechanism of the above-mentioned device is actually used, since the gas flows inside the tank body, it is inevitable that some gas will flow directly out of the tank body when the structure performs the spraying step, resulting in the spraying structure being difficult to fully spray the gas to be purified, thereby reducing the efficiency and effect of the exhaust gas treatment equipment on the exhaust gas treatment. Therefore, a petrochemical exhaust gas treatment equipment is urgently needed to solve the above-mentioned problem. Utility Model Content

[0005] The utility model aims to provide a petrochemical tail gas treatment device to solve the problem that the spray structure of the above-mentioned equipment can achieve the best treatment effect on the tail gas.

[0006] To achieve the above object, the utility model provides the following technical solution: a petrochemical tail gas treatment device, comprising a first tank body, a transport pipe is fixedly connected to the inner top wall of the first tank body, a first water pump is fixedly connected to one end of the top of the transport pipe, a spray groove is provided on the surface of the transport pipe, and a feed pipe is fixedly connected to the bottom of one side of the first tank body;

[0010] Preferably, a second tank body is fixedly connected to one side of the top of the support plate, and slots are provided on both sides of the inner wall of the second tank body.

[0011] Preferably, a guide tube is fixedly connected to the top of the first tank body, and one end of the guide tube is fixedly connected to the bottom of one side of the second tank body, and a first exhaust fan is fixedly connected to the inner wall of the guide tube.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the tail gas treatment liquid is sprayed out through the spray slot to purify the gas in the tank, the electric telescopic rod drives the baffle to move up and down repeatedly. When the baffle rises, it contacts the limit ring, thereby dividing the gas in the tank into multiple groups, and then the tail gas treatment liquid sprayed out of the spray slot sprays each group of gas, and when the baffle descends, the gas in the bottom part rises to the top part, and the baffle is closed again for spraying, so that the gas is layered into multiple groups and sprayed multiple times, avoiding the situation that the gas directly enters the subsequent steps without being sprayed due to flow, so that the tail gas treatment liquid can fully contact with the tail gas, thereby improving the treatment effect of the equipment on petrochemical tail gas.

[0017] 2. After the gas is sprayed by the equipment, the sprayed gas enters the reflux pipe, and the recovered tail gas treatment liquid is transported to the transport pipe again through the second water pump, so that the equipment can reuse the tail gas treatment liquid, thereby effectively avoiding the waste of resources.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 , an embodiment provided by the utility model:

[0028] A petrochemical tail gas treatment device comprises a first tank body 1, a transport pipe 2 is fixedly connected to the inner top wall of the first tank body 1, a first water pump 3 is fixedly connected to one end of the top of the transport pipe 2, a spray groove 4 is provided on the surface of the transport pipe 2, and a feed pipe 16 is fixedly connected to the bottom of one side of the first tank body 1;

[0029] The limiting mechanism includes an electric telescopic rod 5, the top of the electric telescopic rod 5 is fixedly connected to the inner top wall of the first tank body 1, the bottom end of the electric telescopic rod 5 is fixedly connected to a baffle 6, the inner side wall of the first tank body 1 is fixedly connected to a limiting ring 7, the inner side wall of the limiting ring 7 is fixedly connected to a sealing ring 8, and the top of the baffle 6 is overlapped with the bottom of the sealing ring 8, movable grooves 9 are opened on both sides of the inner wall of the baffle 6, and the surface of the transport pipe 2 is overlapped with the inner wall of the movable groove 9, and connecting rods 24 are fixedly connected on both sides of the bottom of the baffle 6.

[0030] After the tail gas is injected into the first tank body 1, the transport pipe 2 is connected to the tail gas treatment liquid, and the tail gas treatment liquid is sprayed out from the spray slot 4 through the first water pump 3 to purify the liquid in the first tank body 1. During the purification, the electric telescopic rod 5 drives the baffle 6 at the bottom to rise. After the baffle 6 rises, it overlaps the bottom of the limit ring 7, so that the sealing ring 8 fills the gap between the limit ring 7 and the baffle 6, thereby dividing the first tank body 1 and the petrochemical tail gas in the first tank body 1 into multiple groups, so that the spray slot 4 sprays each group of gas. After the initial spraying, the baffle 6 is driven to descend by the electric telescopic rod 5, so that a gap is formed between the limit ring 7 and the baffle 6. At this time, the gas divided into multiple groups in the first tank body 1 rises to the area at the top of each group, and then each group of gas is divided by the rising of the baffle 6, so as to perform secondary spraying, and so on.

[0031] See also Figure 3 , 5 7. An embodiment of the present invention is as follows:

[0032] A return pipe 10 is fixedly connected to both sides of the bottom of the first tank body 1 , a second water pump 11 is fixedly connected to the inner wall of the return pipe 10 , and one end of the return pipe 10 is fixedly connected to the top of the transport pipe 2 .

[0033] During spraying, the exhaust gas treatment liquid on the surface of the baffle 6 drips into the inner bottom wall of the first tank body 1 through its own flow when the baffle 6 descends, and then the exhaust gas treatment liquid in the first tank body 1 is transported from the reflux pipe 10 to the transport pipe 2 through the second water pump 11, so as to recycle the exhaust gas treatment liquid.

[0034] Furthermore, a support plate 12 is fixedly connected to the four sides of the bottom of the first tank body 1 , and a support column 13 is fixedly connected to the four sides of the bottom of the support plate 12 .

[0035] The support column 13 can support the bottom of the support plate 12 , and the support plate 12 can support the bottom of the first tank body 1 .

[0036] See also Figure 4-6 , an embodiment provided by the utility model:

[0037] A second tank body 14 is fixedly connected to one side of the top of the support plate 12 , and two sides of the inner wall of the second tank body 14 are provided with clamping grooves 15 .

[0038] Furthermore, a guide tube 17 is fixedly connected to the top of the first tank body 1 , and one end of the guide tube 17 is fixedly connected to the bottom of one side of the second tank body 14 , and a first exhaust fan 18 is fixedly connected to the inner wall of the guide tube 17 .

[0039] Furthermore, a mounting frame 19 is inserted into the inner wall of the card slot 15 , and an activated carbon filter 20 is fixedly connected to the inner wall of the mounting frame 19 .

[0040] After the spraying step in the first tank body 1, the first exhaust fan 18 draws the gas in the first tank body 1 into the second tank body 14 through the guide pipe 17. When the gas rises in the second tank body 14, it gradually penetrates the activated carbon filter 20 in the installation frame 19, thereby filtering the gas. Since the activated carbon filter 20 is divided into three groups, the gas is filtered three times.

[0041] Furthermore, a discharge pipe 21 is fixedly connected to the top of the second tank body 14 , and a second exhaust fan 22 is fixedly connected to the inner wall of the discharge pipe 21 .

[0042] Furthermore, a connecting plate 23 is fixedly connected to the surface of the guide tube 17 , and one side of the connecting plate 23 is fixedly connected to the other side of the first tank body 1 .

[0043] After filtering, the gas is discharged from the discharge pipe 21 through the second exhaust fan 22 , and the connecting plate 23 can fix the guide pipe 17 between the first tank body 1 and the second tank body 14 .

[0044] Working principle: When the equipment is used to treat petrochemical tail gas, the waste gas is first injected into the first tank body 1 through the feed pipe 16, and the tail gas treatment liquid is sprayed out from the spray slot 4 through the first water pump 3 to purify the liquid in the first tank body 1. During purification, the baffle 6 is raised and overlapped to the bottom of the limit ring 7, so that the sealing ring 8 fills the gap between the limit ring 7 and the baffle 6, thereby dividing the gas in the first tank body 1 into multiple groups, and then spraying each group of gas through the spray slot 4. After spraying, the baffle 6 is lowered, so that the gas rises, and then the baffle 6 is raised. This process is repeated to spray the gas in groups for multiple times. During the spraying, the exhaust gas treatment liquid at the spray slot 4 contacts the exhaust gas, so that some harmful substances in the exhaust gas contact and react with the exhaust gas treatment liquid, thereby achieving the purpose of treating the exhaust gas. After spraying, the first exhaust fan 18 transports the gas to the second tank body 14, and the gas is filtered through the activated carbon filter 20. Finally, the gas is discharged from the discharge pipe 21 through the second exhaust fan 22. The exhaust gas treatment liquid is a liquid used for automobile exhaust purification. Its main function is to convert exhaust gas into harmless gas and water.
