Description

Technical Field

[0001] This utility model relates to the field of oily flue gas technology, and in particular to a dust collector for treating oily flue gas. Background Technology

[0002] Flue gas is a mixture of gases and particulate matter, and is a major cause of atmospheric pollution in residential areas. The composition of flue gas is complex, including gases such as water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, while particulate matter includes fuel ash, coal particles, oil droplets, and high-temperature pyrolysis products. Therefore, flue gas pollution is a complex pollution caused by multiple toxic substances. The harmfulness of particulate matter to humans is related to particle size; most harmful particles are those with a diameter of less than 10 μm, with particles of 1-2.5 μm being the most dangerous.

[0003] Some flue gas contains oil. When treating oily flue gas, the viscosity of the oil means that the filter element needs to be replaced very frequently, wasting a lot of resources. When using liquid filtration to filter oil, it is unknown when the liquid needs to be replaced. Therefore, we have proposed a dust collector for treating oily flue gas. Utility Model Content

[0004] The purpose of this utility model is to provide a dust collector for treating oily fumes, so as to solve the technical problems in the prior art.

[0005] This utility model provides a dust collector for treating oily fumes, including a first housing and a filter body. A second housing is fixedly connected to the lower outer part of the first housing, and a circular opening is formed through the upper part of the second housing inside the first housing.

[0006] The upper end of the filter body is fixedly connected to the lower end of the connecting plate, and the connecting plate has several through holes evenly opened inside the upper surface area of ​​the filter body. The upper end of the connecting plate is fixedly connected to the lower end of the transmission rod of the servo motor. The connecting plate is rotatably connected inside the limiting housing, and the servo motor is fixedly connected to the upper middle part of the first housing.

[0007] Preferably, an air inlet pipe is inserted into the lower part of the first housing, the air inlet pipe passes through the second housing, and an air distribution housing is fixedly provided at the air outlet end of the air inlet pipe.

[0008] Preferably, the lower part of the first housing has a liquid level gauge, and the liquid level gauge is provided with a standard water level mark.

[0009] Preferably, the limiting housing is fixedly and sealed to the upper part of the inner cavity of the first housing, and a stabilizing disk is fixedly connected to the upper inner side of the limiting housing through a bracket. The transmission rod of the servo motor is inserted into the middle of the stabilizing disk through a bearing.

[0010] Preferably, the outer side of the connecting plate has an arc groove, and a slip ring is inserted into the inside of the arc groove. The slip ring is fixedly connected to the upper side of the inner wall of the first housing.

[0011] Preferably, a connecting rod is fixedly connected to the lower middle part of the connecting plate, and a reducer is fixedly connected to the lower end of the connecting rod. A stirring rod is fixedly connected to the lower end of the output shaft of the reducer, and a stirring impeller is fixedly connected to the lower end of the stirring rod. The outer side of the reducer is fixedly connected to the inner side of the first housing by a fixing rod.

[0012] Preferably, the front side of the second housing is provided with an observation window, and the front side of the second housing is also connected to a first drain pipe.

[0013] Preferably, a second drain pipe is inserted into the front end of the first housing, and the second drain pipe passes through and is sealed into the second housing. A replenishment pipe is also provided on the upper side of the first housing, and exhaust pipes are fixedly inserted into both sides of the upper end of the first housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Due to the overall structure of the equipment, when the liquid is fully saturated and cannot decompose the oil, the oil will accumulate over time and float on the top of the liquid. When the oil at the top overflows the annular opening, it will enter the interior of the second housing. At this time, the staff can observe the liquid inside the second housing through the observation window, thus reminding the staff that the liquid needs to be replaced.

[0016] Before changing the liquid, the servo motor is accelerated and started, which drives the filter body and the stirring impeller to rotate relatively quickly, causing the liquid to be in a centrifugal state. In this way, most of the oil in the upper part will enter the second housing through the annular opening, and the high-speed rotation of the filter body can shake off the filtered dirt, thus achieving the effect of cleaning the filter body.

[0029] The upper end of the filter body 21 is fixedly connected to the lower end of the connecting plate 20, and the connecting plate 20 has several through holes 17 evenly opened inside the upper surface area of ​​the filter body 21. The upper end of the connecting plate 20 is fixedly connected to the lower end of the transmission rod of the servo motor 2. The connecting plate 20 is rotatably connected inside the limiting housing 12, and the servo motor 2 is fixedly connected to the upper middle part of the first housing 1.

[0030] like Figure 2 As shown: an air inlet pipe 5 is inserted into the lower part of the first housing 1, the air inlet pipe 5 passes through the second housing 6, and an air distribution housing 15 is fixedly provided at the air outlet end of the air inlet pipe 5.

[0031] Specifically, the gas separator shell 15 can evenly divide the gas into several bubbles.

[0032] like Figure 2 As shown: The lower part of the first housing 1 has a liquid level gauge 7, and the liquid level gauge 7 is provided with a standard water level mark.

[0033] Specifically: The level gauge 7 uses a level gauge that is already available on the market.

[0034] like Figure 3 As shown: The limiting housing 12 is fixedly and sealed to the upper part of the inner cavity of the first housing 1. The upper inner side of the limiting housing 12 is fixedly connected to the stabilizing disk 11 by a bracket. The transmission rod of the servo motor 2 is inserted into the middle of the stabilizing disk 11 through a bearing.

[0035] Specifically, the stabilizer 11 can increase the stability of the rotation of the servo motor 2 shaft.

[0036] like Figure 3 As shown: The outer side of the connecting plate 20 has an arc groove, and a slip ring 19 is inserted into the inside of the arc groove. The slip ring 19 is fixedly connected to the upper side of the inner wall of the first housing 1.

[0037] Specifically:

[0038] like Figure 2 As shown: A connecting rod is fixedly connected to the lower middle part of the connecting plate 20, and a reducer 13 is fixedly connected to the lower end of the connecting rod. A stirring rod 14 is fixedly connected to the lower end of the output shaft of the reducer 13. A stirring impeller 16 is fixedly connected to the lower end of the stirring rod 14. The outer side of the reducer 13 is fixedly connected to the inner side of the first housing 1 by a fixing rod.

[0039] Specifically: the reducer 13 can slow down the rotation speed of the stirring rod 14, and the reducer 13 adopts a reducer that is already available on the market.

[0040] like Figure 1 As shown: The front side of the second housing 6 is provided with an observation window 8, and the front side of the second housing 6 is also connected to a first drain pipe 9.

[0041] Specifically: the first drain pipe 9 can drain the liquid inside the second housing 6 and is equipped with a valve.

[0042] like Figure 1 As shown: the front end of the first housing 1 is connected to the second drain pipe 10, and the second drain pipe 10 passes through and is sealed to the second housing 6. The upper side of the first housing 1 is also provided with a replenishment pipe 4, and the upper ends of the first housing 1 are fixedly connected to exhaust pipes 3.

[0043] Specifically: the replenishment pipe 4 can inject liquid into the interior of the first housing 1, and the second drain pipe 10 can drain the liquid inside the first housing 1 and is equipped with a valve.

[0044] Working principle: When the equipment is in normal use, a liquid that can dissolve oil is injected into the first housing 1 through the liquid replenishment pipe 4. The liquid has a specific gravity greater than that of oil. The liquid can be carbon tetrachloride. When the injected liquid just barely overflows the annular port 18, the liquid injection is stopped and the switch valve on the liquid replenishment pipe 4 is closed. Then, gas is introduced.

[0045] The gas first passes through the inlet pipe 5 and is evenly divided into small bubbles by the gas separator shell 15, so that it can be fully mixed with the liquid and the oil in the gas is absorbed and decomposed. At the same time, the servo motor 2 is started to rotate slowly, which makes the connecting plate 20 and the filter body 21 rotate. After being reduced by the reducer 13, the stirring rod 14 and the stirring impeller 16 rotate, thus slowly stirring the liquid. This allows the liquid to fully absorb the oil in the gas. After the oil is absorbed by the liquid, the gas passes upward through the filter body 21 for a second filtration. After the second filtration, the gas is discharged through the exhaust pipe 3.

[0046] When the liquid is fully saturated and cannot decompose the oil, the oil will accumulate over time and float on the top of the liquid. When the oil at the top overflows the annular opening 18, it will enter the interior of the second shell 6. At this time, the staff can observe the liquid inside the second shell 6 through the observation window 8, thus reminding the staff that the liquid needs to be replaced.

[0047] Before changing the liquid, the servo motor 2 is accelerated and started, which drives the filter body 21 and the stirring impeller 16 to rotate relatively quickly, so that the liquid is in a centrifugal state. In this way, most of the oil in the upper part will enter the second housing 6 through the annular port 18, and the filter body 21 rotates at high speed, which can throw off the filtered dirt and achieve the effect of cleaning the filter body 21.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
