Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas purification, and in particular to a desulfurization, denitrification and dust removal equipment with cleaning function. Background Technology

[0002] In the field of industrial flue gas treatment, desulfurization, denitrification, and dust removal are the core links in controlling emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. Traditional equipment typically employs technologies such as wet desulfurization, selective catalytic reduction (SCR) denitrification, electrostatic precipitators, or bag filters. However, these technologies generally suffer from the following problems: the filter media and purifiers require replacement and cleaning after long-term filtration. Traditional equipment integrates the filter media and purifying agents internally, making replacement inconvenient. Therefore, we propose a desulfurization, denitrification, and dust removal device with cleaning capabilities. Utility Model Content

[0003] To address the technical problem of inconvenient replacement of traditional filter media and purifying agents, this utility model provides a desulfurization, denitrification, and dust removal device with cleaning function.

[0004] This utility model is achieved by the following technical solution: a desulfurization, denitrification and dust removal equipment with cleaning function, including a desulfurization and dust removal tower, the desulfurization and dust removal tower including a shell, a lower ear plate fixedly installed at the top of the shell, an upper ear plate fixed above the lower ear plate by fixing bolts, an installation shell fixedly installed at the top of the upper ear plate, and an air pipe opened on the surface of the installation shell.

[0005] The desulfurization and dust removal tower is equipped with a purification and dust removal mechanism, which includes a purification cylinder. The bottom of the purification cylinder is connected to one end of a flue gas pipe, and the other end of the flue gas pipe is connected to a desulfurization and denitrification generation chamber.

[0006] The top of the purification cylinder is threaded with a threaded sleeve. The top of the purification cylinder has an internal thread, and the outer surface of the threaded sleeve has an external thread. The internal and external threads of the purification cylinder and the threaded sleeve engage.

[0007] A clamping plate is fixedly installed on the inner wall of the purification cylinder. An installation plate is set inside the purification cylinder. The installation plate is disc-shaped and its edge is limited above the clamping plate. An assembly threaded sleeve is fixedly installed above the installation plate. An air guide tube is connected to the internal thread of the assembly threaded sleeve. The inner surface of the assembly threaded sleeve has an internal thread, and the top of the air guide tube has an external thread. The air guide tube is engaged into the interior of the assembly threaded sleeve through the thread.

[0008] As a further optimization of this utility model, the top of the purification cylinder is connected to a threaded sleeve via threads, and the threaded engagement structure with internal and external threads facilitates quick disassembly. When the purification agent or internal components need to be replaced or cleaned, the threaded sleeve can be unscrewed to expose the interior of the purification cylinder.

[0009] As a further optimization of this utility model, the air guide tube is connected to the mounting plate by assembling a threaded sleeve. It also adopts a threaded engagement design and can be disassembled and replaced separately without disassembling the entire equipment, thus shortening maintenance time.

[0010] As a further optimization of this utility model, two sets of mesh plates are provided, and the two sets of mesh plates are installed at both ends of the air guide cylinder. During cleaning, the air guide cylinder can be removed to replace the purifying agent, or the particles trapped by the mesh plates can be cleaned, avoiding the inconvenience of replacement caused by the integrated structure of traditional equipment.

[0011] As a further optimization of this utility model, the purifying agent (such as desulfurization and denitrification catalyst or adsorbent) in the air guide tube further purifies the residual sulfur dioxide, nitrogen oxides and particulate matter in the flue gas. The grid sheet fixes the purifying agent and evenly distributes the airflow to ensure full contact and reaction.

[0012] As a further optimization of this utility model, the upper surface of the threaded sleeve is provided with a hole, the connecting sleeve is connected to the purification cylinder through the hole, and an installation pipe is connected to the top of the connecting sleeve, which is connected to the air pipe.

[0013] As a further optimization of this utility model, the purified clean gas enters the connecting cylinder through the top hole of the threaded sleeve, and is discharged from the equipment through the installation pipe and the air pipe, forming a complete airflow path.

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

[0015] 1. The air guide cylinder of this utility model is connected to the mounting plate by a threaded assembly sleeve, both of which adopt a detachable threaded engagement structure. When the purifying agent fails or the mesh traps particles, there is no need to disassemble the entire equipment. Simply unscrew the threaded sleeve and the assembly threaded sleeve to quickly remove the air guide cylinder to replace the purifying agent or clean the mesh, which greatly shortens maintenance time and reduces production interruption losses.

[0016] 2. This utility model uses a guide tube for waste gas to enter the purification cylinder, where the internal purifying agent can deeply purify residual sulfur dioxide, nitrogen oxides, and particulate matter. Two sets of mesh plates fix the purifying agent and evenly distribute the airflow, ensuring full contact and reaction between the flue gas and the purifying agent, improving the synergistic efficiency of desulfurization, denitrification, and dust removal, achieving highly efficient purification of industrial flue gas, and meeting environmental emission requirements.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example 1:

[0028] Please combine Figures 1-7 This embodiment proposes a desulfurization, denitrification and dust removal equipment with cleaning function, including a desulfurization and dust removal tower 1. The desulfurization and dust removal tower 1 includes a shell 11. A lower ear plate 12 is fixedly installed on the top of the shell 11. An upper ear plate 13 is fixed above the lower ear plate 12 by fixing bolts 14. An installation shell 15 is fixedly installed on the top of the upper ear plate 13. An air pipe 16 is opened on the surface of the installation shell 15.

[0029] The desulfurization and dust removal tower 1 is equipped with a purification and dust removal mechanism 4. The purification and dust removal mechanism 4 includes a purification cylinder 41. The bottom end of the purification cylinder 41 is connected to one end of the flue gas pipe 2, and the other end of the flue gas pipe 2 is connected to the desulfurization and denitrification generation chamber 3.

[0030] The top of the purification cylinder 41 is threadedly connected to a threaded sleeve 42. The top of the purification cylinder 41 has an internal thread, and the outer surface of the threaded sleeve 42 has an external thread. The internal and external threads of the purification cylinder 41 and the threaded sleeve 42 engage.

[0031] Specifically, the top of the purification cylinder 41 is connected to the threaded sleeve 42 via threads, and the threaded engagement structure with internal and external threads facilitates quick disassembly. When the purification agent 46 or internal components need to be replaced or cleaned, the threaded sleeve 42 can be unscrewed to expose the interior of the purification cylinder 41.

[0032] A retaining plate 5 is fixedly installed on the inner wall of the purification cylinder 41. The retaining plate 5 has a ring-shaped structure. An installation plate 43 is set inside the purification cylinder 41. The installation plate 43 is disc-shaped and fits against the inside of the purification cylinder 41. The edge of the installation plate 43 is limited above the retaining plate 5. An assembly threaded sleeve 44 is fixedly installed above the installation plate 43. An air guide cylinder 45 is threadedly connected to the inside of the assembly threaded sleeve 44. The inner surface of the assembly threaded sleeve 44 has an internal thread, and the top end of the air guide cylinder 45 has an external thread. The air guide cylinder 45 is threaded into the assembly threaded sleeve 44. The air guide cylinder 45 is connected to the installation plate 43 through the assembly threaded sleeve 44. It also adopts a threaded engagement design and can be disassembled and replaced separately without disassembling the entire equipment, thus shortening maintenance time.

[0033] The air guide cylinder 45 contains a purifying agent 46, and mesh plates 47 are installed at both ends of the cylinder. Two sets of mesh plates 47 are provided, installed at both ends of the air guide cylinder 45. During cleaning, the air guide cylinder 45 is removed to replace the purifying agent 46, or to clean the particles trapped by the mesh plates 47, avoiding the inconvenience of replacement caused by the integrated structure of traditional equipment.

[0034] In the specific technical solution, industrial flue gas first enters the flue gas pipe 2 through the desulfurization and denitrification generation chamber 3. The flue gas is then transported through the flue gas pipe 2 to the bottom of the purification cylinder 41 and upwards through the guide cylinder 45. The purification agent 46 in the guide cylinder 45, such as a desulfurization and denitrification catalyst or adsorbent, further purifies the residual sulfur dioxide, nitrogen oxides, and particulate matter in the flue gas. The mesh plate 47 fixes the purification agent 46 and evenly distributes the airflow to ensure sufficient contact and reaction.

[0035] A further technical solution is provided, in which the upper surface of the threaded sleeve 42 is provided with a hole, and a connecting sleeve 48 is connected above the purification sleeve 41. The connecting sleeve 48 is connected to the purification sleeve 41 through the hole, and an installation pipe 49 is connected above the connecting sleeve 48. The installation pipe 49 is connected to the air pipe 16.

[0036] The purified clean gas enters the connecting cylinder 48 through the top hole of the threaded sleeve 42, and is discharged from the equipment through the installation pipe 49 and the air pipe 16, forming a complete airflow path.

[0037] The working principle of the desulfurization, denitrification, and dust removal equipment with cleaning function described in this patent is as follows:

[0038] Flue gas pretreatment and desulfurization and denitrification

[0039] Industrial flue gas first enters flue gas pipe 2 through desulfurization and denitrification generation chamber 3. The flue gas is then transported through flue gas pipe 2 to the bottom of purification cylinder 41 and upward through guide pipe 45. The purification agent 46 (such as desulfurization and denitrification catalyst or adsorbent) in guide pipe 45 further purifies the residual sulfur dioxide, nitrogen oxides and particulate matter in the flue gas. The mesh plate 47 fixes the purification agent 46 and evenly distributes the airflow to ensure sufficient contact and reaction.

[0040] The purification system features a detachable design for easy cleaning.

[0041] The top of the purification cylinder 41 is connected to the threaded sleeve 42 via threads. The threaded engagement structure with internal and external threads facilitates quick disassembly. When the purification agent 46 or internal components need to be replaced or cleaned, the threaded sleeve 42 can be unscrewed to expose the interior of the purification cylinder 41.

[0042] The air guide tube 45 is connected to the mounting plate 43 by assembling the threaded sleeve 44. It also adopts the threaded engagement design and can be disassembled and replaced separately without disassembling the entire equipment, thus shortening the maintenance time.

[0043] During cleaning, remove the air guide tube 45 to replace the purifier 46, or clean the particles trapped by the mesh plate 47, avoiding the inconvenience of replacement caused by the integrated structure of traditional equipment.

[0044] Airflow circulation and equipment linkage

[0045] The shell 11 of the desulfurization and dust removal tower 1 is connected to the mounting shell 15 through the lower ear plate 12, the upper ear plate 13 and the fixing bolts 14. The air pipe 16 on the surface of the mounting shell 15 is connected to the purification cylinder 41 through the mounting pipe 49 and the connecting cylinder 48.

[0046] The purified clean gas enters the connecting cylinder 48 through the top hole of the threaded sleeve 42, and is discharged from the equipment through the installation pipe 49 and the air pipe 16, forming a complete airflow path.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
