Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment, and specifically to a waste gas cleaning and treatment device. Background Technology

[0002] In chemical production settings, exhaust gas filters are typically used to remove particulate matter from exhaust gases. For example... Figure 1 As shown, the existing exhaust gas filter has a housing S, inside which a filter plate L is installed. The exhaust gas G to be filtered, containing particulate matter such as oil, stone powder, adhesive powder, and thickeners (represented by small circles in the figure), flows in from the bottom of the exhaust gas filter. Most of the particulate matter such as oil, stone powder, adhesive powder, and thickeners is intercepted by the filter plate L, and the filtered exhaust gas G' flows out from the top of the exhaust gas filter.

[0003] Waste gas needs to be treated before it can be discharged; however, existing emission systems suitable for this purpose are generally characterized by complex equipment structures and processes, difficult operation, large overall investment, large footprint, and inconvenient operation and management. Summary of the Invention

[0004] The purpose of this invention is to provide a waste gas cleaning and treatment device to solve the above-mentioned defects caused by the prior art.

[0005] A waste gas cleaning and treatment device includes a purification shell, a purification chamber one, and an adsorption chamber. A perforated plate is connected through one side of the purification shell. A purification chamber two is disposed inside the purification shell. A purification chamber one is connected to one side of the purification chamber two. A purification mechanism is disposed inside the purification chamber one. The purification mechanism guides and purifies the gas, decomposing harmful substances such as formaldehyde and benzene into harmless water and carbon dioxide. An adsorption mechanism is disposed inside the adsorption chamber. The adsorption mechanism adsorbs residual heavy metals, harmful gases, and chemical toxins in the waste gas, reducing the content of harmful substances in the waste gas.

[0006] Preferably, the adsorption mechanism includes a purification box one, an injection pipe, a smoke exhaust fan blade, a catalyst particle mesh box, and a clamp. The injection pipe is connected through one side of the purification box one. A smoke exhaust fan blade is provided inside the purification box one. Catalyst particle mesh boxes are provided inside both the purification box one and the purification box two. A clamp is connected inside both the purification box one and the purification box two. The purification box one is installed inside the purification shell.

[0007] Preferably, the purification box is connected to the output shaft of the bidirectional motor via an internally installed exhaust fan blade.

[0008] Preferably, the purification box is connected to both sides of the catalyst particle mesh box via symmetrically arranged clamps inside.

[0009] Preferably, the adsorption mechanism includes a discharge pipe, an adsorption box, a bidirectional motor, a zeolite disc, a drive shaft, and a bevel gear. The discharge pipe is connected through one side of the adsorption box, the bidirectional motor is arranged directly above the adsorption box, the zeolite discs are symmetrically arranged inside the adsorption box, the end of the drive shaft is connected to the outer side of the adsorption box by a bearing, and the top of the drive shaft is connected to a bevel gear.

[0010] Preferably, the bidirectional motor is connected to bevel teeth on both sides via bevel teeth connected to the output shaft.

[0011] Preferably, the bevel gear is connected to the outer side of the zeolite disc via a drive shaft connected by an outer key.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The airflow speed is increased by rotating one side of the bidirectional motor with the exhaust fan blades, which reduces the internal pressure of the equipment and accelerates the speed at which the equipment extracts external exhaust gas. This prevents the total amount of exhaust gas from impacting the inside of the equipment and causing backflow. At the same time, the flowing exhaust gas repeatedly collides with the particles inside the catalyst particle screen, thereby accelerating the efficiency of particle and exhaust gas purification.

[0014] 2. By stacking the purification chamber 1, purification chamber 2, and adsorption chamber through the purification shell, the height space is saved, the flue gas purification system can be made sufficiently stable, and there is no need to set a long connecting flue between the two. The conical teeth drive the two sets of zeolite discs to rotate, thereby improving the purification effect of the exhaust gas and zeolite discs. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, a waste gas cleaning and treatment device includes a purification shell 1, a purification box 3, and an adsorption box 8. A perforated plate 2 is connected through one side of the purification shell 1. A purification box 6 is arranged inside the purification shell 1. A purification box 3 is connected to one side of the purification box 6. A purification mechanism 7 is arranged inside the purification box 3. The purification mechanism 7 guides and purifies the gas, decomposes harmful substances such as formaldehyde and benzene, and converts them into harmless water and carbon dioxide. An adsorption mechanism 10 is arranged inside the adsorption box 8. The adsorption mechanism 10 adsorbs residual heavy metals such as lead and mercury, harmful gases such as formaldehyde, sulfur dioxide, and chemical toxins in the waste gas, thereby reducing the content of harmful substances in the waste gas.

[0024] In this embodiment, the adsorption mechanism 10 includes a purification box 3, an injection pipe 4, a smoke exhaust fan blade 14, a catalyst particle mesh box 15, and a clamp 16. The injection pipe 4 is connected through one side of the purification box 3. The smoke exhaust fan blade 14 is provided inside the purification box 3. The catalyst particle mesh box 15 is provided inside both the purification box 3 and the purification box 6. The clamp 16 is connected inside both the purification box 3 and the purification box 6. The purification box 3 is installed inside the purification housing 1.

[0025] In this embodiment, the purification box 3 is connected to the output shaft of the bidirectional motor 9 through the internal exhaust fan blades 14. The exhaust fan blades 14 guide and accelerate the flue gas, thereby improving the efficiency of the flue gas colliding with the purified particles.

[0026] In this embodiment, the purification box 3 is connected to both sides of the catalyst particle mesh box 15 through symmetrically arranged clamps 16 inside. The rectangularly distributed clamps 16 are used to position the outside of the catalyst particle mesh box 15 to ensure the stability of the installation of the catalyst particle mesh box 15.

[0027] The adsorption mechanism 10 includes a discharge pipe 5, an adsorption box 8, a bidirectional motor 9, a zeolite disc 11, a drive shaft 12, and a bevel gear 13. The discharge pipe 5 is connected through one side of the adsorption box 8. The bidirectional motor 9 is arranged directly above the adsorption box 8. The zeolite discs 11 are symmetrically arranged inside the adsorption box 8. The tail end of the drive shaft 12 is connected to the outer side of the adsorption box 8 by a bearing. The top end of the drive shaft 12 is connected to the bevel gear 13.

[0028] In this embodiment, the bidirectional motor 9 is connected to the bevel teeth 13 on both sides through the bevel teeth 13 connected to the output shaft. The bevel teeth 13 simultaneously drive the two sets of zeolite discs 11 to rotate, and the zeolite discs 11 are simultaneously adsorbed and filtered.

[0029] In this embodiment, the bevel teeth 13 are connected to the outer side of the zeolite disk 11 via the drive shaft 12 connected by the outer key, and the symmetrically arranged zeolite disks 11 adsorb the flue gas to improve the purification effect of the flue gas.

[0030] In practical applications, this waste gas cleaning and treatment device includes the following tasks:

[0031] Step 1: During use, first select the appropriate size of the catalyst particle screen box 15 according to the amount of exhaust gas, and directly inject the corresponding type of photocatalyst particles into the catalyst particle screen box 15. Then, use the symmetrically set clamps 16 to position the outside of the catalyst particle screen box 15, and then inject the external exhaust gas into the catalyst particle screen box 15. When the granular denitrification agent reacts with the exhaust gas, it can effectively reduce NOx emissions.

[0032] Step 2: The bidirectional motor 9 drives the exhaust fan blades 14, which in turn increase the flow speed of the exhaust gas inside the first purification box 3, accelerating the flow of the exhaust gas. The faster-flowing exhaust gas will disperse after impacting the solid particles that make up the pad layer, and the dispersed exhaust gas will still have a certain flow speed. This further accelerates the injection of the exhaust gas into the second purification box 6, where 0.5-1mm granular activated carbon adsorbs or catalytically reduces and removes sulfides from the flue gas, thereby achieving the purpose of purifying the flue gas.

[0033] Step 3: At the same time, the purified gas is transferred through the exhaust pipe set on one side of the purification box 2 6. During the transfer process, the temperature of the flue gas is reduced, and the heat of the purification box 1 3 and the purification box 2 6 can be transferred and dissipated using the mesh plate 2.

[0034] Step 4: When the flue gas is injected into the adsorption box 8, the bidirectional motor 9 is turned on, and the bidirectional motor 9 drives the bevel gear 13 to rotate. The bevel gear 13 drives the outer bevel gear 13 to mesh, and the bevel gear 13 drives the transmission shaft 12 and the zeolite disc 11 to rotate. When the waste gas containing VOCs passes through the adsorption zone of the zeolite rotor, the VOCs are adsorbed by the zeolite molecular sieve. The purified gas is directly discharged through the discharge pipe 5 set on one side.

[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
