Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to an energy-saving air intake control device for a boiler. Background Technique

[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place where fuel is burned. The boiler includes two major parts: the pot and the furnace. During normal operation, the boiler needs to cooperate with an air intake control device to make the internal combustion more stable.

[0003] For example, the publication number CN218178939U discloses an air intake device for a combustion boiler, which includes a combustion boiler main body, an air inlet pipe and a combustion chamber main body. The inner wall of the combustion boiler main body is fixedly connected with the air inlet pipe and the combustion chamber main body, and the air inlet pipe and the combustion chamber main body are communicated. The inner wall of the combustion boiler main body is fixedly installed with an air supply device for driving air supply. The top of the air inlet pipe is installed with a filtering mechanism for protection. This air intake device can automatically intake air by installing the air supply device and the filtering mechanism. At the same time, it is convenient to quickly connect the air inlet pipe and the mounting rack, and the filter screen can effectively filter. After using for a period of time, manually press to remove the filtering mechanism for maintenance. However, when this air intake device is in use, there are still other deficiencies. The air intake device filters the air through a filter screen. Since the impurity particles in the air are of different sizes, but the filter screen structure of the existing air intake device is single, the filtering efficiency is limited, and it is difficult to filter out particulate matters of different sizes in the air, and it is impossible to remove harmful gases from the air, so the filtering effect of the air used for the boiler is not good. Therefore, when using this device, there are still certain deficiencies. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an energy-saving air intake control device for a boiler, so as to solve the problem that in the current market, when an energy-saving air intake control device for a boiler is in use, due to the different sizes of impurity particles in the air, but the filter screen structure of the existing air intake device is single, the filtering efficiency is limited, it is difficult to filter out particulate matters of different sizes in the air, and it is impossible to remove harmful gases from the air, resulting in poor filtering effect of the air used for the boiler as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An energy-saving air intake control device for a boiler, including a base, a boiler body is fixedly installed on the top of the base, an air inlet pipe is fixedly connected to the right side of the boiler body, an air outlet pipe is fixedly connected to the left side of the boiler body, and a flow velocity measurement sensor body is arranged on the outer wall of the air outlet pipe;

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem that when an energy-saving intake control device of a boiler on the market is in use, due to the different sizes of impurity particles in the air, but the existing filter screen structure of the intake device is single, the filtering efficiency is limited, it is difficult to filter out particulate matters of different sizes in the air, and harmful gases in the air cannot be removed, resulting in poor filtering effect of the air used for the boiler. Refer to Figure 1 and Figure 3 - Figure 7 , sliding grooves 13 are opened inside both sides of the filter box 5, a coarse filter screen plate 14 penetrates through the inside of the sliding grooves 13, a fine filter screen plate is arranged at the bottom of the coarse filter screen plate 14 inside the filter box 5, an adsorption plate 15 is arranged at the bottom of the fine filter screen plate inside the filter box 5, and an activated carbon plate 16 is arranged at the bottom inside the filter box 5. A conveying pipe 9 is fixedly installed on the left side of the main body 8 of the exhaust fan, and the left side of the conveying pipe 9 is connected to the intake pipe 3 through a flange 10. The coarse filter screen plate 14 is detachably connected to the sliding grooves 13 and the movable grooves 12, and metal meshes are arranged inside the coarse filter screen plate 14 and the fine filter screen. A sponge core is arranged inside the adsorption plate 15, and an activated carbon core is arranged inside the activated carbon plate 16.

[0031] By operating the main body 8 of the exhaust fan, the outside air enters the filter box 5 through the connecting pipe 6, so that the air first passes through the wire mesh with larger filter holes in the coarse filter plate 14, and the coarse filter plate 14 intercepts and filters the larger particulate impurities in the air. Then the preliminarily filtered air passes through the wire mesh with smaller filter holes in the fine filter plate, and the small particulate matter in the air can be filtered out. The air after secondary filtration passes through the sponge core in the adsorption plate 15, and the remaining tiny particles and impurities in the air can be adsorbed. The air after multiple filtrations finally passes through the activated carbon core in the activated carbon plate 16, and the harmful gases in the air after multiple filtrations can be removed. Thus, the filtered air is transported into the boiler main body 2 through the connecting pipe 7, the conveying pipe 9 and the intake pipe 3 for use, preventing impurity damage, reducing the failure rate of the boiler, reducing pollutant emissions, and reducing corrosion and wear, thereby improving the combustion efficiency and service life of the boiler.

[0032] Embodiment 2: The intake air volume of the boiler can be controlled to achieve an energy-saving effect. Reference can be made to the attached Figure 1 - attached Figure 4 , including a base 1. A boiler main body 2 is fixedly installed on the top of the base 1. An intake pipe 3 is fixedly connected to the right side of the boiler main body 2, and an exhaust pipe 4 is fixedly connected to the left side of the boiler main body 2. A flow velocity measuring sensor body is arranged on the outer wall of the exhaust pipe 4. A filter box 5 is fixedly installed on the top of the right side of the base 1. A connecting pipe 6 is fixedly connected to the front of the filter box 5. A communicating pipe 7 is fixedly connected to the back of the filter box 5. An exhaust fan main body 8 is arranged behind the communicating pipe 7. A microcomputer controller main body is arranged behind the exhaust fan main body 8 on the right side of the base 1. The conveying pipe 9 is communicated with the intake pipe 3. Two flanges 10 are arranged on the right side of the intake pipe 3.

[0033] The output end of the flow velocity measuring sensor body connected to the exhaust pipe 4 is connected to the receiving end of the microcomputer controller body arranged on the base 1, and the output end of the microcomputer controller body is connected to the receiving end of the exhaust fan main body 8. Thus, the flow velocity of the flue gas discharged from the exhaust pipe 4 connected to the boiler main body 2 is monitored in real time by the flow velocity measuring sensor body, and the signal is transmitted to the microcomputer controller body. Then the microcomputer controller body receives the signal of the flow velocity measuring sensor body and correspondingly outputs a signal to adjust the rotation speed of the exhaust fan main body 8, thereby controlling the intake air volume and achieving an energy-saving effect.

[0034] The above-mentioned flow velocity measurement sensor body (publication number: CN112684204B, which has been disclosed in the existing structure. It calculates the runoff velocity by the water level when the runoff passes through the notch, and the measurement accuracy is relatively low at low flow velocities. In contrast, the present invention directly calculates the runoff velocity through the change in the water level height in the water collecting bucket, greatly improving the accuracy), and the microcomputer controller body (publication number: CN104049558A, which has been disclosed in the existing structure, is a microcomputer controller integrating liquid crystal display, touch button input, harmonic elimination function, three-phase voltage acquisition, communication, real-time fault recording, and fault alarm function), so it will not be elaborated here too much.

[0035] Embodiment 3: The coarse filter plate 14, fine filter plate, adsorption plate 15, and activated carbon plate 16 can be disassembled, replaced, and cleaned. Reference can be made to Appendix Figure 1 , Appendix Figure 3 , and Appendix Figure 5 - Appendix Figure 7 Four movable slots 12 are provided on the front surface of the filter box 5. Four sealing slots 11 are provided on the outer wall of the movable slots 12 on the front surface of the filter box 5. A sealing gasket 18 penetrates through the inside of the sealing slot 11. A sealing plate 17 is fixedly connected to the front surface of the sealing gasket 18. Fastening bolts 19 penetrate through both sides of the sealing plate 17 and the ends are inserted into the filter box 5. The sealing gasket 18 is detachably connected to the sealing slot 11, and the sealing slot 11 is arranged in a mouth-shaped structure.

[0036] By manually pulling out the corresponding fastening bolt 19 from the sealing plate 17, the sealing plate 17 drives the sealing gasket 18 to disengage from the corresponding sealing slot 11. Through the corresponding movable slot 12, the internally installed coarse filter plate 14, fine filter plate, adsorption plate 15, and activated carbon plate 16 are pulled outwards through the corresponding sliding slots 13, so that they can be disassembled, replaced, and cleaned, improving the subsequent air filtration effect.

[0037] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
