Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically a desulfurization and denitrification dust removal device. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. It is crucial for industrial waste gas desulfurization, denitrification, and dust removal.

[0003] Currently, Chinese Patent Publication No. CN105536416A discloses a desulfurization, denitrification, and dust removal device, including a desulfurization and denitrification reaction chamber, a gas-liquid phase separation chamber, and an ash collection hopper. The bottom of the desulfurization and denitrification reaction chamber is connected to the gas-liquid phase separation chamber via a connecting pipe. The ash collection hopper is connected to a dust removal pipe, and the other end of the dust removal pipe is connected to the upper end of the gas-liquid phase separation chamber. The dust removal pipe is connected to an air inlet pipe and contains multiple filter bags. The inner wall of the gas-liquid phase separation chamber is respectively provided with a vertically arranged first coil and a horizontally arranged second coil, with the first coil located above the second coil. Both the first and second coils are connected to liquid inlets. The device has a simple structure, is easy to use, and can effectively achieve desulfurization and denitrification. Furthermore, it can treat particulate matter in flue gas, making the entire treatment process more complete and effective.

[0004] Although the above technical solutions can effectively block dust by utilizing their dustproof functions, the accumulated dust can clog the filter screen over time. It is unclear how to effectively control or remove dust accumulation to ultimately achieve dust removal and improve desulfurization and denitrification efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a desulfurization, denitrification and dust removal device to achieve the purpose of dust removal.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a desulfurization, denitrification, and dust removal device, comprising an integrated desulfurization, denitrification, and dust removal tower, wherein an installation plate is fixedly installed at the flue gas inlet of the integrated desulfurization, denitrification, and dust removal tower, and high-temperature steam inlet pipes for flue gas are integrally connected at equal intervals on the installation plate, an acoustic installation chamber is integrally connected at equal intervals on one side of the integrated desulfurization, denitrification, and dust removal tower, and a steam chamber is integrally connected at the top of the integrated desulfurization, denitrification, and dust removal tower.

[0007] Preferably, the desulfurization, denitrification and dust removal integrated tower is equipped with a dust removal component, which includes a steam pipe, a steam spray hood, an acoustic soot blower and a ceramic fiber filter tube assembly. The steam pipe is integrally connected to the top of the steam chamber and the steam spray hood is integrally connected to the bottom of the steam chamber.

[0008] Preferably, the steam spray cover is provided with an atomizing spray seat, and the atomizing spray seat is provided with steam nozzles that are equidistantly connected around its circumference.

[0009] Preferably, the acoustic soot blowers are equidistantly arranged inside the acoustic installation chamber, and the acoustic soot blowers are arranged in groups of five, for a total of three groups.

[0010] Preferably, the ceramic fiber filter tube assembly is installed inside the desulfurization, denitrification and dust removal integrated tower, and is located below the steam spray hood.

[0011] Preferably, the ceramic fiber filter tube assembly includes coarse ceramic fiber filter tubes and fine ceramic fiber filter tubes, with the fine ceramic fiber filter tubes being equidistantly distributed on both sides of the coarse ceramic fiber filter tubes.

[0012] Preferably, a purification pipe is equidistantly connected to the other side of the integrated desulfurization, denitrification and dust removal tower, and a purification water pipe is connected to one end of the purification pipe. Atomizing spray heads are equidistantly connected to the bottom of the purification water pipe.

[0013] Preferably, the purification pipe, the purification water pipe, and the atomizing spray head together form a spray dust suppression system component.

[0014] Preferably, two sets of wave-type ultra-clean bag filters are installed directly below the spray dust suppression system components.

[0015] Preferably, the bottom of the integrated desulfurization, denitrification and dust removal tower is bucket-shaped, and a connecting seat is built into the bucket opening. A circulation pipe is equidistantly connected around the connecting seat. The other end of the circulation pipe penetrates the outer wall of the integrated desulfurization, denitrification and dust removal tower and extends into the interior, and is located between the spray dust suppression system components and the wave-type ultra-clean bag filter. A flue gas outlet is integrally connected at the middle position of the circulation pipe, and a solenoid valve is installed inside the flue gas outlet.

[0016] This invention provides a desulfurization, denitrification, and dust removal device. It has the following beneficial effects: (1) The present invention sets up a steam chamber for storing steam. When dust removal is carried out, high-pressure steam is used to blow away the accumulated dust inside. The impact force of the steam is greater than that of the soot particles. Under the coverage of the steam nozzle, the soot particles attached to the ceramic fiber filter tube assembly fall off, and then further dust removal is carried out.

[0017] (2) The present invention uses a sonic soot blower to convert compressed air energy into sonic energy through a sonic generator. The sonic energy is then transmitted to the dust accumulation area on the ceramic fiber filter tube assembly by a sonic wave guide. The sonic energy is used to make the dust particles vibrate back and forth, thereby detaching them from the surface of the ceramic fiber filter tube assembly and achieving the purpose of removing dust accumulation.

[0018] (3) By setting up a ceramic fiber filter tube assembly, when the flue gas passes through the ceramic fiber filter tube assembly, the dust is blocked and adsorbed on the surface of the ceramic fiber filter tube assembly, while nitrogen oxides and ammonia enter the interior of the ceramic fiber filter tube assembly. Since the interior of the ceramic fiber filter tube assembly is impregnated with a catalyst, when the flue gas enters the interior of the ceramic fiber filter tube assembly, a reaction occurs under the action of the catalyst, thereby carrying out desulfurization and denitrification. The dust blocked on the outer surface of the ceramic fiber filter tube assembly is blown to the bottom by the sonic soot blower and steam nozzle.

[0019] (4) This invention further reduces dust in the flue gas after desulfurization and denitrification by setting up a spray dust suppression system component and a wave-type ultra-clean bag filter. This causes the dust particles to fall off due to gravity after being covered by moisture. As the wastewater is discharged from the flue gas outlet, the connecting seat is equipped with a flue gas detector to detect parameters such as flue gas content. The detected flue gas content parameters are fed back to the external controller through the circuit. The controller controls the opening and closing of the solenoid valve in the flue gas outlet through the circuit based on the deviation between the actual measured flue gas content and the initial set flue gas content input on the controller. If the initial set flue gas content value is not reached, the flue gas will flow along the circulation pipe under the airflow and eventually flow to the bottom of the spray dust suppression system component to continue the dust suppression work until the initial set flue gas content value is reached.

[0026] A preferred embodiment of the desulfurization, denitrification, and dust removal device provided by the present invention is as follows: Figure 1-6 As shown: A desulfurization, denitrification and dust removal device includes an integrated desulfurization, denitrification and dust removal tower 111. An installation plate 112 is fixedly installed at the flue gas inlet of the integrated desulfurization, denitrification and dust removal tower 111. High-temperature steam inlet pipes 113 are integrally connected and equidistantly arranged on the installation plate 112. An acoustic installation chamber 114 is integrally connected and equidistantly arranged on one side of the integrated desulfurization, denitrification and dust removal tower 111. A steam chamber 115 is integrally connected and arranged at the top of the integrated desulfurization, denitrification and dust removal tower 111. Example 2

[0027] Based on Example 1, a preferred embodiment of the desulfurization, denitrification, and dust removal device provided by the present invention is as follows: Figure 1-6 As shown: The desulfurization, denitrification and dust removal integrated tower 111 is equipped with a dust removal component 2. The dust removal component 2 includes a steam pipe 211, a steam spray hood 212, an acoustic soot blower 215, and a ceramic fiber filter tube assembly 216. The steam pipe 211 is integrally connected to the top of the steam chamber 115, and the steam spray hood 212 is integrally connected to the bottom of the steam chamber 115. An atomizing spray seat 213 is provided on the steam spray hood 212, and steam nozzles 214 are equidistantly connected around the atomizing spray seat 213. By setting up a steam chamber 115 to store steam, when dust removal is carried out, high-pressure steam is used to blow away the accumulated dust throughout the chamber. The impact force of the steam is greater than that of the soot particles. Under the coverage of the steam nozzle 214, the soot particles attached to the ceramic fiber filter tube assembly 216 are dislodged, and further dust removal is carried out.

[0028] The acoustic soot blowers 215 are equidistantly arranged inside the acoustic installation chamber 114, with five acoustic soot blowers per group, for a total of three groups. By setting up an acoustic soot blower 215, compressed air energy is converted into acoustic energy through an acoustic generator. The acoustic energy is then transmitted to the dust accumulation area attached to the ceramic fiber filter tube assembly 216 via an acoustic waveguide. The acoustic energy is used to cause the dust particles to vibrate back and forth, thereby detaching them from the surface of the ceramic fiber filter tube assembly 216 and achieving the purpose of removing the dust accumulation.

[0029] The ceramic fiber filter tube assembly 216 is installed inside the desulfurization, denitrification and dust removal integrated tower 111 and is located below the steam spray hood 212; the ceramic fiber filter tube assembly 216 includes a coarse ceramic fiber filter tube 2161 and a fine ceramic fiber filter tube 2162, and the fine ceramic fiber filter tube 2162 is equidistantly distributed on both sides of the coarse ceramic fiber filter tube 2161. By setting up a ceramic fiber filter tube assembly 216, when flue gas passes through the ceramic fiber filter tube assembly 216, dust is blocked and adsorbed on the surface of the ceramic fiber filter tube assembly 216, while nitrogen oxides and ammonia enter the interior of the ceramic fiber filter tube assembly 216. Since the interior of the ceramic fiber filter tube assembly 216 is impregnated with a catalyst, when the flue gas enters the interior of the ceramic fiber filter tube assembly 216, a reaction occurs under the action of the catalyst, thereby carrying out desulfurization and denitrification. The dust blocked on the outer surface of the ceramic fiber filter tube assembly 216 is blown downwards by the sonic soot blower 215 and the steam nozzle 214, effectively controlling dust accumulation or removing it, thereby ultimately achieving the effect of dust removal and helping to improve the desulfurization and denitrification efficiency.

[0030] On the other side of the desulfurization, denitrification and dust removal integrated tower 111, a purification pipe 221 is equidistantly connected, and a purification water pipe 222 is connected to one end of the purification pipe 221. Atomizing spray heads 223 are equidistantly connected to the bottom of the purification water pipe 222. The purification pipe 221, the purification water pipe 222 and the atomizing spray heads 223 together form a spray dust suppression system component. Two sets of wave-type ultra-clean bag filters 224 are installed directly below the spray dust suppression system components; By setting up a spray dust suppression system component and a wave-type ultra-clean bag filter 224, the flue gas that has already undergone desulfurization and denitrification is further dusted, causing the dust particles to fall due to gravity after being covered by moisture. As the wastewater is discharged from the flue gas outlet 227, the connecting seat 225 contains a flue gas detector to detect parameters such as flue gas content. The detected flue gas content parameters are fed back to an external controller through a circuit. The controller controls the opening and closing of the solenoid valve in the flue gas outlet 227 based on the deviation between the actual measured flue gas content and the initial set flue gas content input to the controller. If the initial set flue gas content value is not reached, the flue gas will be guided by the airflow along the circulation pipe and eventually flow to the area below the spray dust suppression system component to continue dust suppression until the initial set flue gas content value is reached.

[0031] The bottom of the desulfurization, denitrification and dust removal integrated tower 111 is bucket-shaped, and the bucket opening has a built-in connecting seat 225. The connecting seat 225 is equidistantly connected with circulation pipes 226. The other end of the circulation pipe 226 penetrates the outer wall of the desulfurization, denitrification and dust removal integrated tower 111 and extends into the interior, and is located between the spray dust suppression system components and the wave-type ultra-clean bag dust collector 224. The middle position of the circulation pipe 226 is integrally connected with a flue gas outlet 227, and a solenoid valve is installed inside the flue gas outlet 227.

[0033] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
