Description

Technical Field

[0001] This utility model relates to the technical field of flue gas purification equipment, and in particular to an industrial high-temperature flue gas purification device. Background Technology

[0002] Waste incineration is a method of treating waste by burning it at high temperatures, which oxidizes the combustible components into stable gases. The heat generated during incineration can be used to generate electricity, thereby achieving the goals of harmlessness, waste reduction, and resource recovery. It is one of the most commonly used methods for treating urban and rural waste.

[0003] Currently, most purification methods for flue gas generated from coal combustion or waste incineration have some insurmountable drawbacks, such as the generation of large amounts of soot tar, which makes treatment difficult, and the difficulty in completely removing volatile organic compounds. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an industrial high-temperature flue gas purification device. A drive mechanism rotates the spray pipe during the spraying process, ensuring comprehensive spraying of the purification chamber. This allows for more thorough contact and a more complete reaction between the absorbent and the flue gas, improving the purification effect. Furthermore, the flue gas is gradually purified through fiber balls and activated carbon filtration, effectively reducing the dust content in the purified flue gas. The significant purification effect brings great convenience to production and use.

[0005] To solve the above-mentioned technical problems, the present invention adopts an industrial high-temperature flue gas purification device, comprising: a purification chamber, an air outlet at the top of the purification chamber, a sewage outlet at the bottom of the purification chamber, an air inlet on one side of the purification chamber, a spray mechanism on the other side of the purification chamber, and a drive mechanism for driving the spray mechanism to rotate. A first filter mechanism and a second filter mechanism are sequentially arranged above the spray mechanism inside the purification chamber. The first filter mechanism includes a receiving frame inside the purification chamber, and the space of the receiving frame is filled with several fiber balls. The second filter mechanism is a filter plate filled with a solid-phase adsorbent.

[0006] In a preferred embodiment of this invention, the solid-phase adsorbent is activated carbon.

[0007] In a preferred embodiment of this utility model, the fiber ball is formed by weaving modified fiber bundles, and the diameter of the fiber ball is 55-75mm.

[0008] In a preferred embodiment of the present invention, the spraying mechanism includes a spray pipe, one end of which is provided with a plurality of spray heads, and the other end of which extends out of the purification chamber and is connected to the purification chamber through a bearing. A first bevel gear is provided on the pipe body extending out of the purification chamber.

[0009] In a preferred embodiment of this utility model, the spray head is a flat-head atomizing spray head.

[0010] In a preferred embodiment of the present invention, the driving mechanism includes a drive motor disposed on the side wall of the purification chamber and a second bevel gear disposed on the output end of the drive motor, wherein the first bevel gear and the second bevel gear mesh.

[0011] In a preferred embodiment of this utility model, the drive motor is a forward and reverse reversible motor.

[0012] In a preferred embodiment of this utility model, a dust removal bag is fitted onto the air outlet.

[0013] In a preferred embodiment of this utility model, a filter plate is detachably installed inside the sewage outlet.

[0014] In a preferred embodiment of this utility model, the inner upper wall of the purification box is coated with an anti-corrosion coating.

[0015] The beneficial effects of this utility model are as follows: the spray pipe is driven to rotate during the spraying process by the drive mechanism, so that the inside of the purification box is sprayed thoroughly, making the contact between the absorbent liquid and the flue gas more thorough and the reaction more complete, thus improving the purification effect of the flue gas. Then, the flue gas is gradually purified by the fiber balls and activated carbon filtration, which effectively reduces the dust content in the purified flue gas. The purification effect is significant, bringing great convenience to production and use. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 This utility model discloses an industrial high-temperature flue gas purification device, comprising: a purification chamber 1, an air outlet 2 located at the top of the purification chamber, a sewage outlet 3 located at the bottom of the purification chamber, an air inlet 4 located on one side of the purification chamber, a spray mechanism located on the other side of the purification chamber, and a drive mechanism for driving the spray mechanism to rotate. A first filter mechanism and a second filter mechanism are sequentially arranged above the spray mechanism within the purification chamber. Specifically, the first filter mechanism includes a receiving frame 5 located within the purification chamber, and a plurality of fiber balls 6 are arranged and compressed within the space of the receiving frame. The fiber balls are formed by weaving modified fiber bundles, and the diameter of the fiber balls is 55-75 mm, with a distribution density of 6-18 mg / cm³. Several fiber balls adsorb and filter out larger dust particles in the flue gas, and settle and discharge the pollutants under gravity, which can reduce the unevenness of the flue gas filter surface. The second filter mechanism is a filter plate 14 filled with solid adsorbent. The solid adsorbent is activated carbon, which can adsorb and intercept nitrogen oxides and a small amount of acidic gases in the flue gas, and can further adsorb and purify the flue gas.

[0020] Specifically, the spraying mechanism includes a spray pipe 7, with multiple spray heads 8 at one end. The other end of the spray pipe extends outside the purification chamber and is connected to the purification chamber via a bearing. A first bevel gear 9 is installed on the pipe extending out of the purification chamber. The driving mechanism includes a drive motor 10 installed on the side wall of the purification chamber and a second bevel gear 11 installed on the output end of the drive motor. The first bevel gear and the second bevel gear mesh. The drive motor is a forward and reverse motor, and the spray heads are flat-head atomizing nozzles. The two sets of bevel gears can drive the rotation of the spray pipe. A pipe for conveying the prepared spray liquid is connected to the other end of the spray pipe. Multiple spray heads can spray the interior of the purification chamber comprehensively, thereby making the contact between the spray liquid and the flue gas more thorough and the reaction more complete, thus improving the purification effect of the flue gas.

[0021] Specifically, a dust bag 12 is fitted onto the air outlet to perform a final filtration of the purified gas. A filter plate 13 is detachably installed inside the drain outlet. The inner upper wall of the purification chamber is coated with an anti-corrosion coating to reduce the degree of corrosion of the inner wall of the purification chamber caused by acidic substances in the flue gas and improve its service life.

[0022] The beneficial effects of this utility model are as follows: the spray pipe is driven to rotate during the spraying process by the drive mechanism, so that the inside of the purification box is sprayed thoroughly, making the contact between the absorbent liquid and the flue gas more thorough and the reaction more complete, thus improving the purification effect of the flue gas. Then, the flue gas is gradually purified by the fiber balls and activated carbon filtration, which effectively reduces the dust content in the purified flue gas. The purification effect is significant, bringing great convenience to production and use.
