Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically, it relates to a waste gas treatment device for a drying furnace used in titanium zirconium ore processing. Background Technology

[0002] Titanium zirconium ore is a scarce resource. Due to its special metallic properties, it is widely used in industries such as precision casting, advanced refractory materials, aerospace, and medical chemicals.

[0003] With the large-scale development of the titanium zirconium ore processing industry, the amount of exhaust gas emitted from drying furnaces is increasing day by day. In order to meet environmental protection requirements and achieve sustainable development, reducing pollutant emissions in exhaust gas and improving exhaust gas purification efficiency has become an industry consensus. In the existing technology, static adsorption and filtration devices are mostly used for the treatment of exhaust gas from titanium zirconium ore processing drying furnaces, such as traditional fixed bed molecular sieve adsorption equipment and single filter dust removal devices.

[0004] However, current waste gas treatment equipment still has the following defects in actual use. First, under static treatment, the contact area and contact time between waste gas and purification materials are limited, resulting in low adsorption and sieving efficiency of molecular sieves for pollutants in waste gas, making it difficult to achieve efficient purification of waste gas.

[0005] Secondly, existing equipment lacks an automatic cleaning mechanism. During long-term waste gas treatment, the intercepted particulate matter tends to accumulate inside the equipment, which not only affects gas flow but also reduces the activity and lifespan of the purification materials. Frequent manual cleaning operations increase maintenance costs and affect production continuity. Therefore, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a waste gas treatment device for a drying furnace for titanium zirconium ore processing that can overcome or at least partially solve the above problems.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0009] Preferably, the rotating shaft is rotatably connected to the connecting seat, a protrusion is fixedly connected to the rotating shaft, a guide groove is provided on the roller, the protrusion is slidably connected in the guide groove, a rotary joint is provided on one end of the rotating shaft, the end of the air supply pipe that communicates with the air supply chamber is provided on the rotary joint, and a drive mechanism for driving the rotating shaft to rotate the roller is provided on the connecting seat.

[0010] In order to drive the drum to rotate synchronously with the shaft and accelerate the purification efficiency of the exhaust gas, the drive mechanism further includes a motor, which is fixedly mounted on the connecting seat, and gears that mesh with each other are fixedly mounted on the output end of the motor and on the shaft.

[0011] To increase the sealing at the connection between the collection bin and the roller, preferably, a sealing gasket is provided on one end of the roller, and the sealing gasket is in contact with the collection bin.

[0012] To facilitate the cleaning of particulate matter impurities collected in the collection chamber, the collection chamber is further detachably connected to the roller via fixing bolts.

[0013] For preliminary filtration of exhaust gas, preferably, a filter box is also included, the fixing ring is fixedly connected to the filter box, the bottom of the filter box is fixedly connected to an air inlet pipe, the filter box stores an appropriate amount of water for preliminary filtration of exhaust gas, and the end of the air supply pipe away from the air supply chamber is connected to the upper end of the filter box.

[0014] To further filter the pre-filtered exhaust gas, multiple activated carbon filters are inserted into the filter box, and one end of the gas supply pipe connected to the filter box is located above the activated carbon filters.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A waste gas treatment device for a drying furnace used in titanium-zirconium ore processing includes a fixed ring 2, and further includes: a drum 201 rotatably connected to the fixed ring 2, wherein a zeolite molecular sieve cylinder 204 is provided inside the drum 201, and an exhaust hole is provided on the drum 201; a collection bin 202 detachably connected to one end of the drum 201; a sealing plug 3 slidably connected to the zeolite molecular sieve cylinder 204; an electric telescopic rod 302 fixedly installed on the fixed ring 2, wherein the telescopic end of the electric telescopic rod 302 is fixedly connected to a connecting seat 303; a rotating shaft 301, one end of which is inserted into the drum 201 and fixedly connected to the sealing plug 3, wherein the rotating shaft 301 and the sealing plug 3 are provided with a gas delivery chamber 401 communicating with the drum 201, and the rotating shaft 301 is connected to the connecting seat 303; and a gas delivery pipe 4 is provided on the rotating shaft 301 and communicates with the gas delivery chamber 401.

[0026] The rotating shaft 301 is rotatably connected to the connecting seat 303. A protrusion 304 is fixedly connected to the rotating shaft 301. A guide groove is provided on the roller 201. The protrusion 304 is slidably connected in the guide groove. A rotary joint is provided on one end of the rotating shaft 301. The end of the air supply pipe 4 that is connected to the air supply chamber 401 is provided on the rotary joint. A drive mechanism for driving the rotating shaft 301 to drive the roller 201 to rotate is provided on the connecting seat 303.

[0027] The drive mechanism includes a motor 305, which is fixedly mounted on a connecting seat 303. Gears 306 that mesh with each other are fixedly mounted on the output end of the motor 305 and on the rotating shaft 301.

[0028] It also includes a filter box 1, a fixing ring 2 fixedly connected to the filter box 1, an air inlet pipe 101 fixedly connected to the bottom of the filter box 1, an appropriate amount of water for preliminary filtration of exhaust gas stored in the filter box 1, and an end of the air supply pipe 4 away from the air supply chamber 401 connected to the upper end of the filter box 1.

[0029] Multiple activated carbon filters 102 are inserted into the filter box 1, and the end of the gas supply pipe 4 connected to the filter box 1 is located above the activated carbon filters 102.

[0030] During use, the high-temperature exhaust gas generated by the drying oven enters the filter box 1 through the air inlet pipe 101. The exhaust gas comes into contact with the water in the filter box 1. The water uses its own characteristics of intercepting particulate matter and absorbing soluble acidic gases to perform preliminary filtration of the exhaust gas. Most of the particulate matter and soluble acidic gases are absorbed by the water, while large particulate matter settles at the bottom of the filter box 1. At the same time, the exhaust gas is cooled down. After preliminary water treatment, a small part of the gas containing particulate matter floats upward and passes through the activated carbon filter screen 102. The activated carbon relies on the strong adsorption field of its well-developed pore structure and microporous organization to adsorb the particulate matter in the gas, completing the secondary filtration. The pre-treated exhaust gas enters the gas transmission pipe 4.

[0031] The pretreated exhaust gas enters the rotary joint through the gas delivery pipe 4. The rotary joint ensures that the gas delivery is not affected by the rotation of the shaft 301. Then, it is delivered to the drum 201 through the gas delivery chamber 401. Subsequently, it passes through the zeolite molecular sieve cylinder 204. The zeolite molecular sieve cylinder 204 uses the pore size sieving characteristics to adsorb molecules smaller than its pore size and repel molecules larger than its pore size, thus filtering the particulate matter again and blocking the particulate matter in the drum 201. The clean gas is discharged into the air through the exhaust port, achieving deep purification.

[0032] After the exhaust gas enters the drum 201, the motor 305 is started. The motor 305 drives the rotating shaft 301 to rotate through the meshing gears 306. When the rotating shaft 301 rotates, the protrusion 304, under the limiting action of the guide groove, drives the drum 201 to rotate synchronously. The rotating zeolite molecular sieve cylinder 204 accelerates its contact with the gas entering the drum 201, increasing the filtration speed. At the same time, the electric telescopic rod 302 is activated. The electric telescopic rod 302 drives the connecting seat 303 and the rotating shaft 301 to move, causing the sealing plug 3 to slide back and forth inside the zeolite molecular sieve cylinder 204. When the sealing plug 3 slides towards the collection chamber 202, the internal space of the drum 201 gradually shrinks and the internal pressure gradually increases, further accelerating the contact between the exhaust gas and the rotating zeolite molecular sieve cylinder 204, improving the filtration efficiency. In addition, when the sealing plug 3 slides towards the collection chamber 202, it can also push the particles blocked in the drum 201 into the collection chamber 202, preventing the accumulation of a large number of particles in the drum 201 during the process of filtering and purifying the exhaust gas, which would affect the efficiency of the zeolite molecular sieve cylinder 204 in filtering and purifying the exhaust gas.

[0033] It should be noted that a one-way valve is installed on gas pipeline 4;

[0034] To facilitate regular cleaning of the water in filter box 1, a drain pipe with a valve switch (not shown in the figure) can be added to the bottom of filter box 1 to facilitate regular cleaning of the water in filter box 1.

[0035] Example 2: Refer to Figure 1 , Figure 5 A waste gas treatment device for a drying furnace for processing titanium zirconium ore is basically the same as that in Example 1. Furthermore, a sealing gasket 203 is provided on one end of the drum 201, and the sealing gasket 203 is in contact with the collection bin 202.

[0036] When the collection chamber 202 is installed at one end of the roller 201, the collection chamber 202 and the sealing gasket 203 fit tightly together, which can effectively prevent the waste gas from leaking through the gap at the connection between the collection chamber 202 and the roller 201 during the waste gas treatment process, ensuring that the waste gas can be fully filtered, adsorbed and purified, improving the cleanliness of the final exhaust gas and avoiding environmental pollution caused by waste gas leakage.

[0037] The collection chamber 202 is detachably connected to the roller 201 by fixing bolts;

[0038] When it is necessary to clean the particulate matter collected in the collection chamber 202, the fixing bolts can be unscrewed to remove the collection chamber 202 from the roller 201, which facilitates the cleaning of the particulate matter collected in the collection chamber 202. After cleaning, the collection chamber 202 can be reinstalled on the roller 201 using the fixing bolts to continue the exhaust gas treatment work. The detachable connection characteristic of the fixing bolts enables convenient installation and removal between the collection chamber 202 and the roller 201.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
