Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of boiler explosion prevention, in particular to a boiler furnace protection equipment with an explosion-proof structure. BACKGROUND

[0002] The combustion wave propagating at subsonic speed is called deflagration. It is the phenomenon that the combustible mixture accumulated in the furnace burns at the same time, so that the pressure on the flue gas side of the furnace suddenly rises. In severe cases, the pressure generated by deflagration can exceed the allowable value of the designed structure, causing damage to the water wall, rigid beam and furnace roof and wall. The generation of deflagration must have three conditions (i.e. three elements of deflagration), none of which can be omitted. One is the accumulation of fuel and combustion air; two is that the fuel and air mixture reaches the deflagration concentration; three is the presence of sufficient ignition energy.

[0003] Therefore, how to avoid the accumulation of fuel and combustion air during the start, operation and shutdown of the boiler is the key to preventing furnace deflagration. Once the deflagration occurs, the gas will expand and cause damage to the boiler and the burner, which cannot ensure personal safety. SUMMARY

When there is a lot of dust attached to the inner wall of the pipe, in order to ensure ventilation of the pipe and rapid introduction of oxygen, the cleaning component can help reduce the deposition of debris on the inner wall of the pipe, maintain smooth ventilation, and avoid the backflow of fly ash produced by combustion, which affects the use of the fan.

[0048] 3. The present invention sets a monitoring component, and the flue gas enters through the shell and contacts the monitoring module, so that the monitoring module detects the concentration of carbon monoxide. The cooling pipe is connected to the cooling box externally, so that the coolant cools the monitoring module. After the monitoring is completed, the monitoring module and the shell are retracted into the box, and the baffle is closed to protect the monitoring module to avoid direct contact with the flue gas.

[0049] 4. The present invention sets a scraping assembly, and the curved plate drives the special-shaped rods to approach the scraper. The special-shaped rods are squeezed by the curved plate and open each other, so that the end of the special-shaped rod close to the scraper is opened, thereby driving the special-shaped rods to move to both sides along the bottom of the shell, so that the scraper cleans the fly ash at the bottom of the shell, so that the flue gas can contact the monitoring module in time. At the same time, the curved plate reduces the flue gas flow entering the shell at the bottom. After cleaning is completed, the curved plate is opened again, so that the scraper is in the middle position of the bottom of the shell again, allowing the flue gas to enter the shell.

DETAILED DESCRIPTION

[0059] The present application will be further described below in conjunction with the drawings and specific embodiments. The embodiments of the present application are given for illustration and description only, and are not intended to be exhaustive or to limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application for various embodiments with various modifications as are suited to the particular use contemplated.

[0060] Embodiment 1, please refer to Figure 1-Figure 5 The present application provides a technical solution: a boiler furnace protection equipment with anti-explosion structure is described as follows.

[0061] It comprises:

[0062] The boiler body 1 has a combustion chamber 7 formed in the inner wall thereof, and an air duct 8 formed in the inner wall of the boiler body 1 near one side of the combustion chamber 7;

[0063] The mounting plate 3 is arranged on the top of the boiler body 1;

[0064] The air induction mechanism 4 is mounted on the top of the mounting plate 3;

[0065] The monitoring mechanism 5 is installed on the top of the mounting plate 3 and away from the side of the air inducing mechanism 4;

[0066] The boiler furnace protection device with an anti-explosion structure also includes:

[0067] The combustion engine 2 is installed on the side of the boiler body 1 close to the combustion chamber 7;

[0068] The smoke exhaust pipe 6 is installed on the side of the boiler body 1 away from the combustion engine 2.

[0069] During operation, before the combustion engine 2 is turned on, the induced draft mechanism 4 blows air into the combustion chamber 7 for a period of time to blow out the combustible gas retained in the combustion chamber 7. Then the boiler body 1 starts to work, fuel is introduced, and the combustion engine 2 is turned on. The exhaust gas generated by the combustion is transmitted to the smoke exhaust pipe 6 through the air duct 8. The concentration of carbon monoxide in the smoke is detected by the monitoring mechanism 5. When the concentration of carbon monoxide is high, the induced draft mechanism 4 is turned on again to introduce oxygen into the boiler body 1, so that the boiler body 1 can burn more fully during operation, reduce the production of carbon monoxide, and thus reduce the occurrence of deflagration.

[0070] The air induction mechanism 4 includes:

[0071] The fan 401 is arranged on the top of the mounting plate 3;

[0072] Pipe 402, the outer wall of the fan 401 is provided with a pipe 402, which is installed on the top of the inner wall of the boiler body 1. A valve is provided inside the lower part of the pipe 402, and the valve is opened when the fan 401 is turned on;

[0073] Cleaning assembly 403 , which is installed on the top of the inner wall of pipe 402 .

[0074] Before combustion begins, the fan 401 is turned on to ventilate the interior of the boiler body 1 through the pipe 402. When a large amount of carbon monoxide is produced during the combustion process, the fan 401 is turned on again to introduce oxygen into the boiler body 1 to make the combustion more complete and reduce the production of carbon monoxide. When a large amount of dust adheres to the inner wall of the pipe 402, in order to ensure ventilation of the pipe 402 and rapid introduction of oxygen, the cleaning component can help reduce the deposition of debris on the inner wall of the pipe 402, maintain smooth ventilation, and avoid the backflow of fly ash produced by combustion, which affects the use of the fan 401.

[0075] The monitoring body 5 also includes:

[0076] Box 504, box 504 is installed on the top of the inner wall of the boiler body 1, so that the monitoring component 507 can be retracted into the box 504 for storage when not in use;

[0077] The baffle 505 is arranged on the inner wall of the boiler body 1 close to the box body 504. The outer wall of the baffle 505 is slidably connected to the inner wall of the boiler body 1. The baffle 505 isolates the monitoring component 507 from the boiler body 1 when the monitoring component 507 is retracted.

[0078] Monitoring agencies 5 include:

[0079] A drive box 501 is provided on the top of the mounting plate 3, and a drive rod 502 is installed on the outer wall of the drive box 501;

[0080] The threaded rod 503 is threadedly connected to the inner wall of the driving rod 502, and the threaded rod 503 moves up and down under the drive of the driving rod 502;

[0081] Monitoring assembly 507, the top of which is rotatably connected to the bottom of the threaded rod 503, and the monitoring assembly 507 is used to monitor the concentration of carbon monoxide in the boiler body 1 in real time;

[0082] The scraping assembly 508 is installed at the bottom of the monitoring assembly 507 . The scraping assembly 508 is used to keep the flue gas in the boiler body 1 in contact with the monitoring assembly 507 .

[0083] The monitoring body 5 also includes:

[0084] Cooling box 506, cooling box 506 is installed on the top of driving box 501, the outer wall of cooling box 506 is connected with the top of monitoring assembly 507, the inner wall of box body 504 is connected with the outer wall of threaded rod 503, and cooling liquid is filled in cooling box 506.

[0085] During operation, the baffle 505 opens, and the driving rod 502 drives the threaded rod 503 to move downward, so that the monitoring component 507 moves downward from the box 504 to the vicinity of the smoke exhaust pipe 6, so that the monitoring component 507 measures the carbon monoxide concentration of the flue gas generated by combustion. When a high carbon monoxide concentration is detected, the draft mechanism 4 needs to be opened. The content of fly ash and other debris in the flue gas is high. The scraping component 508 cleans the bottom of the monitoring component 507 so that the flue gas can pass through the monitoring component 507, thereby detecting the carbon monoxide concentration. Check once every period of time to avoid carbon monoxide accumulation and explosion accidents.

[0086] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on Example 1, the cleaning component 403 includes:

[0087] Telescopic rod 4031, which is installed on the top of pipe 402;

[0088] Circular plate 4032 is mounted on the bottom of telescopic rod 4031. The top of circular plate 4032 is rotatably connected to the bottom of telescopic rod 4031. The surface of circular plate 4032 is evenly provided with air holes 4033. The edge of circular plate 4032 contacts the inner wall of pipe 402, so that debris attached to the inner wall of pipe 402 is scraped off.

[0089] The filter screen 4034 is rotatably mounted on the inner wall of the circular plate 4032 .

[0090] Before the boiler body 1 starts working, the circular plate 4032 is located at the top of the pipe 402 under the drive of the telescopic rod 4031, so that the gas sent by the fan 401 is directly transmitted to the interior of the boiler body 1 through the pipe 402. During combustion, when a high carbon monoxide content is detected in the boiler body 1, the valve inside the pipe 402 is opened, allowing the fan 401 to transport oxygen into the boiler body 1. Fly ash generated during combustion will enter along the pipe 402. At this time, the telescopic rod 4031 drives the circular plate 4032 to be located below the pipe 402, and the filter 4034 rotates out of the circular plate 4032 to block the air vent 4033. This allows the airflow to be smoothly transported into the boiler body 1 while preventing fly ash from entering the pipe 402 and affecting the fan 401. The airflow in the boiler body 1 is maintained, reducing the occurrence of deflagration.

[0091] Monitoring component 507 includes:

[0092] The outer wall of the housing 5071 is slidably connected to the inner wall of the air duct 8. The upper and lower surfaces of the housing 5071 are evenly provided with sieve holes 5072. The top of the housing 5071 is rotatably connected to the bottom of the threaded rod 503.

[0093] Monitoring module 5073 , which is installed on the inner wall of the box 504 , is used to monitor the concentration of carbon monoxide in the flue gas inside the air duct 8 .

[0094] The monitoring component 507 also includes:

[0095] Cooling pipe 5074: The top of cooling pipe 5074 is connected to the outer wall of cooling box 506. The outer wall of cooling pipe 5074 is sleeved with the inner wall of housing 5071. Cooling pipe 5074 is in contact with the outer wall of monitoring module 5073, so that the temperature of monitoring module 5073 is lower than the flue gas temperature, maintaining the normal function of monitoring module 5073.

[0096] Motor 5075 , the motor 5075 is arranged on the outer wall of the shell 5071 , and the motor 5075 is used to drive the scraping component 508 .

[0097] When detection is required, the threaded rod 503 drives the shell 5071 to descend to a position near the smoke exhaust pipe 6, and the smoke passes through the shell 5071 and comes into contact with the monitoring module 5073, so that the monitoring module 5073 detects the concentration of carbon monoxide. The cooling pipe 5074 is externally connected to the cooling box 506, so that the coolant cools the monitoring module 5073. After the monitoring is completed, the monitoring module 5073 and the shell 5071 are retracted into the box 504, and the baffle 505 is closed to protect the monitoring module 5073 to avoid direct contact with the smoke. The carbon monoxide content in the smoke is monitored in real time, and measures can be taken in time to reduce the carbon monoxide concentration, thereby avoiding the accumulation of too much combustible gas and causing deflagration.

[0098] The scraping assembly 508 includes:

[0099] A bent plate 5081 is rotatably mounted on the outer wall of the housing 5071 , with one side of the bent plate 5081 connected to the outer wall of the motor 5075 ;

[0100] The limiting rod 5082 is symmetrically provided on the inner wall of the bent plate 5081 , and the outer wall of the limiting rod 5082 is slidably connected to the inner wall of the bent plate 5081 ;

[0101] The special-shaped rod 5083 has one end which is sleeved on the outside of the limiting rod 5082. Two special-shaped rods 5083 are symmetrically provided. The limiting rod 5082 allows the special-shaped rod 5083 to move freely, but moves with the bent plate 5081. The two special-shaped rods 5083 are movably connected at the contact position.

[0102] The support sleeve 5085, the top of the support sleeve 5085 is installed on the outer wall of the shell 5071, the inner wall of the support sleeve 5085 is socketed with the outer wall of the special-shaped rod 5083, and the inner wall of the support sleeve 5085 is socketed with the connection between the special-shaped rod 5083, so that the special-shaped rod 5083 is further supported.

[0103] The scraping assembly 508 also includes:

[0104] The scraper 5084 is symmetrically arranged at the bottom of the housing 5071. The top of the scraper 5084 is slidably connected to the bottom of the housing 5071. The inner wall of the scraper 5084 is rotatably and slidably connected to one end of the special-shaped rod 5083.

[0105] A separator 5086 is installed at the bottom of the housing 5071 and is located between the two special-shaped rods 5083. The separator 5086 is used to separate the special-shaped rods 5083 to both sides when the special-shaped rods 5083 are close to each other.

[0106] Spring 5087, spring 5087 is installed on the opposite side of the scraper 5084. When the two scrapers 5084 are in the middle position, the spring 5087 is in a normal state. When the two scrapers 5084 are separated from each other, the spring 5087 is stretched, so that the spring 5087 generates a pulling force to drive the special-shaped rod 5083 to return to its original position.

[0107] During use, due to the large amount of fly ash in the flue gas, it is particularly easy to block the bottom of the shell 5071, so that the flue gas cannot quickly contact the monitoring module 5073, resulting in untimely monitoring. At this time, the motor 5075 drives the bent plate 5081 to rotate, causing the bent plate 5081 to rotate downward, so that the bent plate 5081 drives the special-shaped rod 5083 to approach the scraper 5084. The special-shaped rod 5083 is squeezed and opened by the bent plate 5081, so that the end of the special-shaped rod 5083 close to the scraper 5084 is opened, thereby driving the special-shaped rod 5083 to move to both sides along the bottom of the shell 5071, so that the scraper 5084 cleans the fly ash at the bottom of the shell 5071, so that the flue gas can contact the monitoring module 5073 in time. At the same time, the bent plate 5081 reduces the flue gas flow entering the shell 5071 at the bottom. After cleaning is completed, the bent plate 5081 is opened again, so that the scraper 5084 is again in the middle position of the bottom of the shell 5071, allowing flue gas to enter the shell 5071.

[0108] The specific workflow is as follows:

[0109] During operation, before the combustion engine 2 is turned on, the induced draft mechanism 4 blows air into the combustion chamber 7 for a period of time to blow out the combustible gas retained in the combustion chamber 7. Then the boiler body 1 starts to work, fuel is introduced, and the combustion engine 2 is turned on. The exhaust gas generated by the combustion is transmitted to the smoke exhaust pipe 6 through the air duct 8. The baffle 505 is opened, and the driving rod 502 drives the threaded rod 503 to move downward, so that the monitoring component 507 moves downward from the box body 504 to the vicinity of the smoke exhaust pipe 6, so that the monitoring component 507 measures the carbon monoxide concentration of the flue gas generated by the combustion. When a high carbon monoxide concentration is detected, the induced draft mechanism 4 needs to be turned on. The content of fly ash and other debris in the flue gas is high, and the scraping component 508 cleans the bottom of the monitoring component 507 so that the flue gas can pass through the monitoring component 507, thereby detecting the carbon monoxide concentration;

[0110] When a lot of dust adheres to the inner wall of the pipe 402, in order to ensure ventilation of the pipe 402 and rapid oxygen flow, the cleaning component can help reduce the deposition of debris on the inner wall of the pipe 402 and maintain smooth ventilation;

[0111] When the concentration of carbon monoxide is high, the induced draft mechanism 4 is opened again to introduce oxygen into the boiler body 1, so that the boiler body 1 can burn more completely during operation, reduce the generation of carbon monoxide, and thus reduce the occurrence of deflagration.

[0112] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
