Description

Technical Field

[0001] This utility model relates to the field of boiler dust removal technology, specifically a boiler dust removal and ash removal gas source mixing and collection device. Background Technology

[0002] Boilers inevitably generate dust and flue gas during operation. Boiler dust removal separates dust from the flue gas, thereby reducing dust pollution and facilitating further treatment such as desulfurization and denitrification of the flue gas. With social development, environmental protection is receiving increasing attention, and boiler dust removal has been applied to various fields, including thermal power generation.

[0003] The existing boiler dust removal solution is one electrostatic precipitator and one bag filter per boiler, which uses electric cleaning. The electric field uses top electromagnetic hammer vibration cleaning, and the bag field uses pulse jet cleaning. The cleaning is carried out by connecting the main pipes in series.

[0004] Currently, the pulse valves for cleaning the baghouse of electrostatic precipitators and baghouse dust collectors frequently leak air due to the lack of air source collection, resulting in insufficient air source pressure, high operating resistance of the electrostatic precipitators and a significant increase in plant power consumption. To address this, we provide a boiler dust removal and cleaning air source mixing and collection device. Utility Model Content

The preliminary filter screen is fixedly installed inside the gas source collection device, and the fine filter screen is fixedly installed inside the gas source collection device located behind the preliminary filter screen.

[0013] As a further embodiment of this utility model: the adsorption filter is fixedly installed inside the gas source collection device, located behind the fine filter, and the adsorption groove is formed inside the adsorption filter.

[0014] As a further embodiment of this utility model: the vibration assembly includes a vibration motor, a vibration shaft, a vibration support, and a vibration plate. The vibration motor is fixedly installed at the top of the air source collection device, and the vibration shaft is fixedly installed at the output end of the vibration motor.

[0015] As a further embodiment of this invention: the vibration support is fixedly installed on the outside of the vibration shaft, and the vibration plate is fixedly installed at the end of the vibration support.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses a cyclone separator to clean the airflow drawn from the outside, separating relatively large particles from the airflow to prevent large dust particles from accumulating inside the pipe and affecting the normal operation of the electrostatic precipitator / bag filter. Through multi-stage filtration, impurities inside the airflow are separated, allowing larger dust particles to be filtered down by the preliminary and fine filters. The active adsorbent material inside the adsorption tank adsorbs oil, particulate matter, and other substances in the airflow, preventing them from mixing and forming mud-like substances that clog the pipes.

[0021] 2. This utility model uses a vibration motor to drive the vibration shaft to rotate, which in turn moves the vibration support and vibration plate. This causes the vibration plate to strike and vibrate the filter screen, causing residues on the filter screen to fall off and preventing them from clogging the filter screen and affecting the normal filtration efficiency. The cooling plate lowers the temperature inside the air source collection device, causing water vapor in the humid gas to condense on the inner wall of the air source collection device, preventing water vapor from mixing with dust to form mud-like substances that clog the pipes. An automatic drain ball valve drains excess water from inside the air source collection device, preventing liquid water from occupying space and reducing the effective air supply.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1:

[0032] Please see Figure 1 - Figure 4 This is the first embodiment of the present utility model.

[0033] This embodiment provides a boiler dust removal and ash cleaning gas source mixing and collection device, including: a gas source collection device 1, a gas flow pipe 2, an air pump 3, and an air box 9; the gas flow pipe 2 is fixedly installed on the side of the gas source collection device 1, the air pump 3 is fixedly installed at the end of the gas flow pipe 2, and the air box 9 is fixedly installed at the end of the gas flow pipe 2, and also includes:

[0034] Cyclone separator 4, filter 5, vibration 6, cooling 7 and drainage 8; Cyclone separator 4 is installed on the side of air pump 3, filter 5 is installed inside air source collection device 1, vibration 6 is installed at the top and inside of air source collection device 1, cooling 7 is installed on the side and inside of air source collection device 1, and drainage 8 is installed inside and at the bottom of air source collection device 1.

[0035] Specifically, the cyclone separator assembly 4 includes a cyclone separator 41, an inlet pipe 42, a dust collection box 43, and an outlet pipe 44. The outlet pipe 44 is fixedly installed on the side of the air pump 3, and the cyclone separator 41 is fixedly installed in front of the outlet pipe 44. The inlet pipe 42 is fixedly installed on the side of the cyclone separator 41, and the dust collection box 43 is detachably installed at the bottom of the cyclone separator 41.

[0036] Furthermore, the cyclone separator 41 can clean the airflow drawn from the outside, separating relatively large particles from the airflow to prevent large dust particles from accumulating inside the pipe and affecting the normal operation of the electrostatic precipitator / bag filter.

[0037] Specifically, the filter assembly 5 includes a preliminary filter 51, a fine filter 52, an adsorption filter 53, and an adsorption tank 54. The preliminary filter 51 is fixedly installed inside the gas source collection device 1, and the fine filter 52 is fixedly installed inside the gas source collection device 1, located behind the preliminary filter 51. The adsorption filter 53 is fixedly installed inside the gas source collection device 1, located behind the fine filter 52, and the adsorption tank 54 is formed inside the adsorption filter 53.

[0038] Furthermore, through multi-stage filtration, impurities inside the airflow are separated, allowing larger dust particles to be filtered down by the preliminary filter screen 51 and the fine filter screen 52, and allowing the active adsorbent material inside the adsorption tank 54 to adsorb oil, particulate matter and other substances in the airflow, so that they do not mix and form mud-like substances that block the pipes.

[0039] In use, gas enters the cyclone separator 41 through the inlet pipe 42. Due to the incident angle, the airflow spirals inside the cyclone separator 41, constantly impacting the inner wall of the cyclone separator 41. During the movement, larger dust particles slide down the inner wall of the cyclone separator 41 to the dust collection box 43 below. When the airflow reaches the cone at the bottom of the cyclone separator 41, the cone changes the spiral radius and direction of movement, causing the airflow to be discharged from the outlet pipe 44 at the top. The air pump 3 delivers the airflow through the air pipe 2 to the interior of the air source collection device 1. After processing, the airflow is distributed to each air box 9 through the air pipe 2. Inside the air source collection device 1, the airflow passes through the preliminary filter screen 51, the fine filter screen 52, and the adsorption filter screen 53 for filtration. The adsorption tank 54 inside the adsorption filter screen 53 contains adsorption material, which adsorbs oil, particulate matter, and other substances in the airflow, preventing them from mixing and forming mud that clogs the pipes.

[0040] In summary, the cyclone separator 41 can clean the airflow drawn from the outside, separating relatively large particles from the airflow to prevent large dust particles from accumulating inside the pipe and affecting the normal operation of the electrostatic precipitator / bag filter. Through multi-stage filtration, impurities inside the airflow are separated, allowing larger dust particles to be filtered down by the preliminary filter screen 51 and the fine filter screen 52. The active adsorbent material inside the adsorption tank 54 adsorbs oil, particulate matter, and other substances in the airflow, preventing them from mixing and forming mud that clogs the pipes.

[0041] Example 2:

[0042] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0043] Specifically, the vibration assembly 6 includes a vibration motor 61, a vibration shaft 62, a vibration support column 63, and a vibration plate 64. The vibration motor 61 is fixedly installed at the top of the air source collection device 1, and the vibration shaft 62 is fixedly installed at the output end of the vibration motor 61. The vibration support column 63 is fixedly installed on the outside of the vibration shaft 62, and the vibration plate 64 is fixedly installed at the end of the vibration support column 63.

[0044] Furthermore, the vibration motor 61 drives the vibration shaft 62 to rotate, which in turn moves the vibration support 63 and the vibration plate 64, causing the vibration plate 64 to strike and vibrate the filter screen, causing the residue on the surface of the filter screen to fall off, preventing the residue from clogging the filter screen and affecting the normal filtration efficiency.

[0045] Specifically, the cooling assembly 7 includes a cooling box 71, a cooling plate 72, a water inlet pipe 73, and a water outlet pipe 74. The cooling box 71 is fixedly installed on the side of the air source collection device 1, and the cooling plate 72 is fixedly installed inside the air source collection device 1 and the cooling box 71. The water inlet pipe 73 is fixedly installed on the side of the cooling box 71, and the water outlet pipe 74 is fixedly installed on the side of the cooling box 71.

[0046] Furthermore, the cooling plate 72 lowers the temperature inside the gas source collection device 1, causing water vapor in the humid gas to condense on the inner wall of the gas source collection device 1, preventing water vapor from mixing with dust to form mud that blocks the pipes.

[0047] Specifically, the drainage assembly 8 includes an automatic drainage ball valve 81 and a water collection tank 82. The automatic drainage ball valve 81 is fixedly installed on the inner wall of the bottom end of the air source collection device 1, and the water collection tank 82 is fixedly installed at the bottom end of the air source collection device 1, located below the automatic drainage ball valve 81.

[0048] Furthermore, the excess water inside the gas source collection device 1 is drained by the automatic drain ball valve 81 to prevent liquid water from occupying space and reducing the effective gas supply.

[0049] In use, the vibration motor 61 drives the vibration shaft 62 to rotate, causing the vibration support column 63 and the vibration plate 64 to rotate, which knocks on the preliminary filter screen 51, the fine filter screen 52, and the adsorption filter screen 53, causing the residue on their surfaces to fall off and preventing them from clogging the filter screens. The cooling plate inside the cooling box 71 lowers the temperature inside the air source collection device 1 and raises the temperature inside the cooling box 71. Water is injected into the cooling box 71 through the water inlet pipe 73 and discharged through the water outlet pipe 74, thus preventing the temperature inside the cooling box 71 from getting too high. Through the setting of the cooling component 7, the water in the humid air inside the air source collection device 1 condenses inside the air source collection device 1. When there is a lot of water inside the air source collection device 1, the ball head of the automatic drain ball valve 81 rises, driving the valve to move, allowing the water to be discharged from the air source collection device 1 and collected into the water collection tank 82, preventing the water from mixing with dust to form mud-like substances that adhere to pipe bends and valves and clog the pipes.

[0050] In summary, the vibration motor 61 drives the vibration shaft 62 to rotate, which in turn moves the vibration support 63 and the vibration plate 64. This causes the vibration plate 64 to strike and vibrate the filter screen, causing the residue on the filter screen to fall off and preventing the residue from clogging the filter screen and affecting the normal filtration efficiency. The cooling plate 72 lowers the temperature inside the air source collection device 1, causing water vapor in the humid gas to condense on the inner wall of the air source collection device 1, preventing water vapor from mixing with dust to form mud that clogs the pipes. The automatic drain ball valve 81 drains excess water from inside the air source collection device 1, preventing liquid water from occupying space and reducing the effective air supply.
