Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust equipment, in particular to an efficient and low-dust vertical boiler flue pipe. Background Technique

[0002] When a boiler burns fuel, it is necessary to ensure the air circulation in the internal combustion chamber. Therefore, the flue gas generated by combustion needs to be discharged through a smoke exhaust pipe, and these flue gases mainly contain water vapor, carbon dioxide, nitrogen, and other combustion products;

[0003] Existing vertical smoke exhaust pipes are generally made of high-temperature resistant materials such as stainless steel or galvanized plates. Their structures are mainly designed to meet the smooth flow and discharge requirements of flue gas. Therefore, this type of smoke exhaust pipe does not have a dust filtration structure, so that when the flue gas is discharged through the smoke exhaust pipe, a certain amount of dust particles will be discharged at the same time. This direct discharge method will pollute the surrounding environment. At the same time, the increase of a large number of dust particles in the surrounding air environment will also cause harm to the respiratory systems of the people moving around. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an efficient and low-dust vertical boiler flue pipe, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A sewage pipe is fixedly installed at the bottom of the dust settling water tank, and a sewage valve is fixedly installed at the bottom of the sewage pipe. Shunt pipes are fixedly installed on both sides of the dust settling water tank. A fixed pipe is fixedly installed at the top of the dust settling water tank, and a smoke exhaust pipe is fixedly installed at the top of the fixed pipe. A rain shield is arranged at the top of the smoke exhaust pipe, and the rain shield is fixedly installed at the top of the smoke exhaust pipe through a plurality of support rods.

[0007] Preferably, an exhaust pipe is fixedly installed at the top of the dust settling water tank, and dust settling water is stored in the dust settling water tank.

[0008] Preferably, intake pipes are fixedly installed on both sides of the dust settling water tank. An acceleration cover is fixedly installed at the bottom of the intake pipe. The longitudinal section of the acceleration cover is in a horn shape, and the acceleration cover is placed in the dust settling water tank. Through the arrangement of the intake pipe and the acceleration cover, the flue gas can be accelerated into the dust settling water tank by using the principle of gradually shrinking the channel, so that the flue gas impacts the water body in the dust settling water tank at a high speed, thereby improving the interception effect of dust particles in the flue gas.

[0009] Preferably, one ends of the two shunt pipes are fixedly connected through a boiler connection pipe. The ends of the two shunt pipes far from the boiler connection pipe are respectively fixedly connected to one ends of the corresponding intake pipes. And the end of the boiler connection pipe far from the shunt pipe is connected to the exhaust end of the boiler. With the arrangement of the boiler connection pipe and the shunt pipes, the flue gas discharged from the boiler can be shunted into the two intake pipes, so that without affecting the flue gas emission volume, the flue gas can impact the water body in the dust-removing water tank at a high speed for dust-removing treatment.

[0010] Preferably, flanges are fixedly installed at both the top and bottom of the fixed pipe. A first connection seat is fixedly installed on the outer side of the fixed pipe. The first connection seat is connected to the output end of an external delivery pump through a connecting pipe. A plurality of second connection seats are fixedly installed inside the fixed pipe.

[0011] Preferably, an atomizing nozzle is threadedly connected inside the second connection seat. The fixed pipe is fixedly installed between the exhaust pipe and the smoke exhaust pipe through the flange at the top. With the arrangement of the fixed pipe and the atomizing nozzles, the flue gas that has undergone primary dust-removing treatment can be subjected to secondary dust-removing, so as to improve the low-dust effect of flue gas emission.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] For the high-efficiency low-dust vertical boiler flue pipe of the present utility model, with the arrangement of the dust-removing water tank, shunt pipes, fixed pipes, intake pipes, and acceleration covers, the flue gas discharged from the boiler can be shunted to impact the dust-removing water body in the dust-removing water tank, so that the dust particles collide with the water body and decelerate, and the water body in the dust-removing water tank captures the dust particles. At the same time, with the cooperation of the water mist sprayed by a plurality of atomizing nozzles, the particulate matter content in the flue gas can be further reduced, thus achieving the low-dust effect of flue gas emission.

[0019] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0020] As Figures 1-4 shown, the high-efficiency and low-dust vertical boiler flue pipe provided by the present utility model includes a dust-settling water tank 1. A drain pipe 2 is fixedly installed at the bottom of the dust-settling water tank 1, and a drain valve 3 is fixedly installed at the bottom of the drain pipe 2. Diverging pipes 4 are fixedly installed on both sides of the dust-settling water tank 1. A fixed pipe 5 is fixedly installed at the top of the dust-settling water tank 1, a smoke exhaust pipe 6 is fixedly installed at the top of the fixed pipe 5, a rain shield 7 is arranged at the top of the smoke exhaust pipe 6, and the rain shield 7 is fixedly installed at the top of the smoke exhaust pipe 6 through a plurality of support rods 8.

[0021] As Figure 2 shown, an exhaust pipe 11 is fixedly installed at the top of the dust-settling water tank 1. Dust-settling water is stored in the dust-settling water tank 1. Air inlet pipes 9 are fixedly installed on both sides of the dust-settling water tank 1. An acceleration hood 10 is fixedly installed at the bottom of the air inlet pipe 9. The longitudinal section of the acceleration hood 10 is in a horn shape, and the acceleration hood 10 is placed in the dust-settling water tank 1. Through the arrangement of the air inlet pipe 9 and the acceleration hood 10, the flue gas can be accelerated into the dust-settling water tank 1 by using the principle of gradually reducing the channel, so that the flue gas impacts the water body in the dust-settling water tank 1 at a high speed, thereby improving the interception effect of dust particles in the flue gas;

[0022] As Figure 1 、 Figure 3 shown, one ends of the two diverging pipes 4 are fixedly connected through a boiler connection pipe 12. The ends of the two diverging pipes 4 far from the boiler connection pipe 12 are respectively fixedly connected to one ends of the corresponding air inlet pipes 9. The end of the boiler connection pipe 12 far from the diverging pipe 4 is connected to the exhaust end of the boiler. By means of the arrangement of the boiler connection pipe 12 and the diverging pipes 4, the flue gas discharged from the boiler can be diverted into the two air inlet pipes 9, so that the flue gas can impact the water body in the dust-settling water tank 1 at a high speed for dust-settling treatment without affecting the flue gas emission volume;

[0023] As Figure 1 、 Figure 4As shown, flanges are fixedly installed at both the top and bottom of the fixed pipe 5. A first connection seat 13 is fixedly installed on the outer side of the fixed pipe 5. The first connection seat 13 is connected to the output end of an external delivery pump through a connecting pipe. A plurality of second connection seats 14 are fixedly installed inside the fixed pipe 5. An atomizing nozzle 15 is connected to the second connection seat 14 by internal threads. The fixed pipe 5 is fixedly installed between the exhaust pipe 11 and the smoke exhaust pipe 6 through the flange at the top. Through the arrangement of the fixed pipe 5 and the atomizing nozzle 15, the flue gas that has undergone primary dust reduction treatment can be subjected to secondary dust reduction, thereby improving the low-dust effect of flue gas emission.

[0024] It should be noted that the present utility model is an efficient low-dust vertical boiler flue pipe. When the boiler exhausts air outward through a fan, the flue gas enters the boiler connection pipe 12, and the boiler connection pipe 12 diverts the flue gas through two shunt pipes 4 into the corresponding intake pipes 9. Thus, when the flue gas flows through the acceleration cover 10, its cross-sectional area gradually decreases. When a fluid passes through a channel with a reduced cross-section, its flow rate will increase accordingly. Therefore, the flue gas will impact the water body in the dust reduction water tank 1 at a high speed. Furthermore, due to the inertia of the dust particles, the dust particles will maintain a certain state of motion and collide with the water body. When the dust particles collide with the water body, the speed of the dust particles will gradually slow down until the speed reduces to zero. At this time, the momentum of the particles also becomes zero, and finally, they adhere to the surface of the water and are captured by the water, thereby being able to reduce the content of dust particles in the flue gas. After the flue gas that enters the dust reduction water tank 1 undergoes the first dust reduction treatment by the water body, the flue gas enters the smoke exhaust pipe 6 again through the exhaust pipe 11. At the same time, a plurality of atomizing nozzles 15 located between the exhaust pipe 11 and the smoke exhaust pipe 6 spray mist water into the dust reduction water tank 1, thereby reducing the particle content in the flue gas once again. Thus, the flue gas after two dust reduction treatments is discharged through the smoke exhaust pipe 6, effectively reducing the particulate matter content in the flue gas.
