Description

Technical Field

[0001] This utility model belongs to the field of industrial waste gas desulfurization technology, specifically relating to an integrated industrial waste gas desulfurization device. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. In particular, waste gas generated from chemical plants, steel mills, pharmaceutical factories, coking plants, oil refineries, and other sources, as well as from daily life, produces strong-smelling waste gases that seriously pollute the environment and affect human health.

[0003] Desulfurization is a crucial step in industrial waste gas treatment. Desulfurization units effectively filter sulfides and other harmful substances from the waste gas using various filtration mechanisms. However, these filtration devices encounter a problem during operation: waste gas typically contains a large amount of dust, which can clog the filters, especially the top-level ones. Due to dust accumulation, the top-level filters are the first to become clogged. While the lower filters can still be used, their overall filtration efficiency is affected. Because the top-level filters are prone to clogging, workers have to frequently open the unit's cover for cleaning to ensure its normal operation. This frequent cleaning not only increases the workload for workers but may also lead to increased equipment maintenance costs.

[0004] To address the aforementioned issues, this application proposes an integrated industrial waste gas desulfurization device. Utility Model Content

[0009] Two mounting boxes are bolted to one side of the filter box. Each mounting box has a pair of L-shaped fixing plates fixed inside. Four pairs of sliding rods pass through each pair of L-shaped fixing plates. A return spring is sleeved on the outer wall of each sliding rod. The return spring is located between the U-shaped frame and the L-shaped fixing plate. One end of each pair of sliding rods is fixed to the U-shaped frame, and the other end is threaded with a nut. Positioning rollers for inserting into the arc-shaped positioning groove are rotatably connected to each pair of U-shaped frames.

[0010] Preferably, a water pipe is installed inside the discharge box, and several nozzles are installed at equal intervals on the water pipe.

[0011] Preferably, a pair of sliding grooves are provided on both sides of the two mounting boxes, and mounting rods are fixed on both pairs of U-shaped frames. Both ends of the mounting rods pass through the sliding grooves and are fitted with nuts by threads.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides the following technical solution: an integrated desulfurization equipment for industrial waste gas, including a filter box 1 and an exhaust box 22. The filter box 1 and the exhaust box 22 are connected by a second connecting pipe 21. A second cover door 23 is connected to one side of the exhaust box 22 by a hinge, and an exhaust pipe 24 is installed on the top. An air pump 27 is installed on both the exhaust pipe 24 and the second connecting pipe 21.

[0027] The top of the filter box 1 is equipped with a first connecting pipe 2, and a first cover door 3 is installed on one side via a hinge. Two activated carbon layers 5 are installed at equal intervals inside the filter box 1. A filter screen 4 is installed inside the filter box 1 above the activated carbon layers 5. A detachable filter screen 7 is installed inside the filter box 1 above the filter screen 4 and close to the first connecting pipe 2. A pull rod 28 is fixed on one side of the filter screen 7.

[0028] The filter box 1 has an installation groove 8 for the filter screen 7 to pass through. A pair of connecting rods 9 are fixed on one side of the filter screen 7 frame. A pair of clearance grooves 20 for the connecting rods 9 to pass through are opened on one side of the filter box 1. Two inclined grooves 11 are opened at one end of each pair of connecting rods 9, and two arc-shaped positioning grooves 10 are opened on the outer wall.

[0029] Two mounting boxes 12 are bolted to one side of the filter box 1. Each mounting box 12 has a pair of L-shaped fixing plates 13 fixed inside. Four pairs of sliding rods 14 pass through each pair of L-shaped fixing plates 13. A return spring 19 is fitted onto the outer wall of each sliding rod 14, located between the U-shaped frame 15 and the L-shaped fixing plates 13. One end of each pair of sliding rods 14 is fixed to the U-shaped frame 15, and the other end is threaded with a nut. Positioning rollers 16 for inserting into the arc-shaped positioning groove 10 are rotatably connected to each pair of U-shaped frames 15. During operation, firstly, the exhaust gas enters the interior of the filter box 1 through the first connecting pipe 2. The exhaust gas is first initially filtered by the filter screen 7, which effectively removes fine particulate matter. Then, the exhaust gas continues to flow downward and passes through the filter screen 4, which can capture even finer particulate matter to ensure the cleanliness of the emitted gas. Next, the exhaust gas passes through the activated carbon layer 5, which has a strong adsorption capacity and can effectively remove harmful gases and odors from the exhaust gas. The gas treated by the activated carbon layer 5 is purified inside the filter box 1.

[0030] Subsequently, the gas enters the discharge box 22 through the second connecting pipe 21. The discharge box 22 is equipped with a water pipe 25, and several nozzles 26 are installed at equal intervals on the water pipe 25. Inside the discharge box 22, these nozzles 26 can spray water mist to further cool and wash the gas, removing any small particles and harmful substances that may remain in the gas. After being washed, the gas is finally discharged through the exhaust pipe 24. Throughout the process, the air pump 27 is responsible for maintaining the airflow circulation of the system to ensure that the exhaust gas can pass through smoothly.

[0031] When installing the filter screen 7, it is inserted through the mounting groove 8, and then the connecting rod 9 is positioned inside the mounting box 12 by passing through the clearance groove 20. The connecting rod 9 uses two inclined grooves 11 to pass between the two positioning rollers 16 and simultaneously squeezes the two positioning rollers 16, causing them to push the two pairs of sliding rods 14 to move to both sides and drive the U-shaped frame 15 to move. The U-shaped frame 15 simultaneously squeezes the return spring 19, causing it to contract. When the arc-shaped positioning groove 10 moves to align with the position of the positioning rollers 16, the return spring 19 springs the U-shaped frame 15 back to its original position, so that the positioning rollers 16 are embedded inside the arc-shaped positioning groove 10, thereby realizing the quick installation and positioning of the filter screen 7.

[0032] When disassembling filter screen 7, simply pull the lever 28 outward to disengage the positioning roller 16 from the arc-shaped positioning groove 10, then pull the connecting rod 9 out of the clearance groove 20, and filter screen 7 can be removed from the mounting groove 8, making it easy to disassemble filter screen 7. This avoids the need to frequently open the first cover door 3 to disassemble filter screen 7. When there is a lot of dust accumulated on the filter screen, the top layer filter screen 7 can be directly disassembled and cleaned without disassembling the filter device below it, thus avoiding affecting the overall filtration efficiency. This reduces the need for staff to frequently open the cover door of the device for cleaning, ensuring the normal operation of the filter device.

[0033] Specifically, by Figure 4 As shown in this embodiment, a pair of sliding grooves 18 are provided on both sides of the two mounting boxes 12, and mounting rods 17 are fixed on both pairs of U-shaped frames 15. Both ends of the mounting rods 17 pass through the sliding grooves 18 and are fitted with nuts by threads. This can increase the stability of the U-shaped frames 15 during movement, ensuring that the installation and removal of the filter screen 7 is smoother and more reliable. In addition, the design of the sliding grooves 18 allows the U-shaped frames 15 to maintain parallel movement during sliding, avoiding jamming caused by tilting.

[0034] Specifically, by Figure 5 As shown, in this embodiment, both pairs of positioning rollers 16 are made of nylon; they have good wear resistance and self-lubrication, which can effectively reduce the friction of the equipment during operation and extend the service life of the equipment. At the same time, when the nylon positioning rollers 16 come into contact with the arc-shaped positioning groove 10, they can reduce the generation of noise and make the equipment run more quietly.

[0035] Specifically, by Figure 1 and Figure 4As shown in this embodiment, the filter screen 7 is provided with a sealing strip on its frame; this can effectively prevent gas leakage and ensure the filtration effect. The material of the sealing strip is selected to have a certain degree of elasticity and corrosion resistance to adapt to the harsh environment of industrial waste gas treatment. After the filter screen 7 is installed in place, the sealing strip can fit tightly against the inner wall of the installation groove 8, thereby forming a sealed space to prevent the purified gas from mixing with the untreated waste gas, thus ensuring the high efficiency and safety of gas treatment.

[0036] Specifically, by Figure 5 As shown in this embodiment, the L-shaped fixing plate 13, the slide bar 14, and the U-shaped frame 15 are all made of metal, possessing good mechanical strength and durability.

[0037] It should be noted that the air pumps 27 are all commercially available standard equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated on further in this article.

[0038] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0039] Components not described in detail in this article are existing technologies.

[0040] The working principle and usage process of this utility model are as follows: During use, firstly, the exhaust gas enters the interior of the filter box 1 through the first connecting pipe 2. The exhaust gas is first initially filtered by the filter screen 7, which effectively removes small particulate matter. Subsequently, the exhaust gas continues to flow downward and passes through the filter screen 4. The filter screen 4 can capture even finer particulate matter, ensuring the cleanliness of the emitted gas. Then, the exhaust gas passes through the activated carbon layer 5. The activated carbon layer 5 has a very strong adsorption capacity and can effectively remove harmful gases and odors from the exhaust gas. The gas treated by the activated carbon layer 5 is purified inside the filter box 1.

[0041] Subsequently, the gas enters the discharge box 22 through the second connecting pipe 21. The discharge box 22 is equipped with a water pipe 25, and several nozzles 26 are installed at equal intervals on the water pipe 25. Inside the discharge box 22, these nozzles 26 can spray water mist to further cool and wash the gas, removing any small particles and harmful substances that may remain in the gas. After being washed, the gas is finally discharged through the exhaust pipe 24. Throughout the process, the air pump 27 is responsible for maintaining the airflow circulation of the system to ensure that the exhaust gas can pass through smoothly.

[0042] When installing the filter screen 7, it is inserted through the mounting groove 8, and then the connecting rod 9 is positioned inside the mounting box 12 by passing through the clearance groove 20. The connecting rod 9 uses two inclined grooves 11 to pass between the two positioning rollers 16 and simultaneously squeezes the two positioning rollers 16, causing them to push the two pairs of sliding rods 14 to move to both sides and drive the U-shaped frame 15 to move. The U-shaped frame 15 simultaneously squeezes the return spring 19, causing it to contract. When the arc-shaped positioning groove 10 moves to align with the position of the positioning rollers 16, the return spring 19 springs the U-shaped frame 15 back to its original position, so that the positioning rollers 16 are embedded inside the arc-shaped positioning groove 10, thereby realizing the quick installation and positioning of the filter screen 7.

[0043] When disassembling filter screen 7, simply pull the lever 28 outward to disengage the positioning roller 16 from the arc-shaped positioning groove 10, then pull the connecting rod 9 out of the clearance groove 20, and filter screen 7 can be removed from the mounting groove 8, making it easy to disassemble filter screen 7. This avoids the need to frequently open the first cover door 3 to disassemble filter screen 7. When there is a lot of dust accumulated on the filter screen, the top layer filter screen 7 can be directly disassembled and cleaned without disassembling the filter device below it, thus avoiding affecting the overall filtration efficiency. This reduces the need for staff to frequently open the cover door of the device for cleaning, ensuring the normal operation of the filter device.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
