Description

Technical Field

[0001] The utility model relates to the field of low - nitrogen burners, and specifically relates to a staged gas low - nitrogen burner. Background Technique

[0002] A low - nitrogen burner is a device that adds a blower, an induced draft fan, a frequency converter, uses control valves and multiple circuit integrations to the traditional burner to make clean energy and the burner operate to provide more efficient heat energy for the boiler. The generation of nitrogen oxides in low - nitrogen combustion is part of the combustion reaction: the nitrogen oxides generated by combustion are mainly NO and NO2, collectively referred to as NOx.

[0003] According to a staged gas low - nitrogen burner with the publication number CN219510788U, it includes a base. The left end of the upper surface of the base is fixedly installed with a burner. The left end of the burner is fixedly installed with a gas staging pipe. The right end of the upper surface of the base is fixedly installed with a filter box. The right end of the burner is fixedly installed with an air outlet pipe.

[0004] However, when the above - mentioned disclosed patent purifies the flue gas, it uses multiple groups of atomizing nozzles to purify it. However, the purification effect of the atomizing nozzles is not good, and it is easy to cause a small amount of NOx to still be contained in the discharged flue gas. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide a staged gas low - nitrogen burner to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A staged gas low - nitrogen burner, including a low - nitrogen burner body. A purification box is installed on one side of the low - nitrogen burner body, and an air outlet pipe is arranged on one side of the low - nitrogen burner body. The air outlet pipe penetrates into the interior of the purification box. A gas staging pipe is arranged on one side of the low - nitrogen burner body. A purification chamber and a filtration chamber are arranged inside the purification box. Multiple groups of partition plates are fixedly installed inside the purification chamber. A gas guide pipe is installed on the inner wall of the filtration chamber, and the end of the gas guide pipe penetrates into the purification chamber. Activated carbon is arranged inside the filtration chamber, and an exhaust pipe is arranged inside the filtration chamber.

[0007] By adopting the above technical solution, the problem of poor gas purification effect in the prior art is solved. When the gas enters the purification chamber through the outlet pipe, under the action of the dispersion plate, the discharged gas can be dispersed, so as to come into contact with the water in the purification chamber. Since there are multiple partition plates, the gas can fully contact with the water, and the partition plates are inclined, so the gas is discharged slowly. Moreover, the diameter of the air duct is smaller than that of the outlet pipe, and the diameter of the exhaust pipe is smaller than that of the air duct, which will cause the air pressure in the purification chamber to rise. Therefore, the water at the bottom of the purification chamber will enter the upper part of the purification chamber through the circulation pipe, enabling the internal water to circulate, better purifying the discharged gas. The purified gas enters the activated carbon through the air duct, so as to purify the gas again, and finally is discharged through the exhaust pipe.

[0008] The utility model is further configured such that a water inlet valve is provided at the top of the purification tank, a liquid discharge valve is provided at the bottom of the purification tank, and both the liquid discharge valve and the water inlet valve penetrate into the interior of the purification chamber.

[0009] By adopting the above technical solution, the water inlet valve provided can facilitate adding water into the purification chamber, and the setting of the drain valve can facilitate discharging the water inside the purification chamber.

[0010] The utility model is further configured such that the partition plates are inclined, the partition plates are evenly distributed inside the purification chamber, and every two groups of the interior of the purification chamber are arranged staggeredly.

[0011] By adopting the above technical solution, the staggeredly inclined partition plates can enable the gas to more fully contact and react with the water inside the purification chamber, and prevent the gas from being discharged immediately.

[0012] The utility model is further configured such that the diameter of the air duct is smaller than that of the outlet pipe, and the diameter of the exhaust pipe is smaller than that of the air duct.

[0013] By adopting the above technical solution, the smaller diameter of the air duct than that of the outlet pipe will cause the gas to be discharged slowly, so that a large amount of gas will not enter the filtration chamber at the same time, and the gas purification effect is better. The smaller diameter of the exhaust pipe enables the purified gas not to be discharged immediately in the filtration chamber.

[0014] The utility model is further configured such that a baffle is installed on one side of the purification tank by bolts, and a sealing gasket is provided on one side of the baffle.

[0015] By adopting the above technical solution, the provided baffle can be conveniently disassembled, so as to facilitate replacing the activated carbon inside the purification tank.

[0016] The utility model is further configured such that a dispersion plate is fixed at the bottom end of the inner wall of the purification chamber, and the dispersion plate is conical.

[0017] By adopting the above technical solution, the conical dispersion plate can make the gas discharged from the air outlet pipe disperse better in the purification chamber, so as to be able to contact water better.

[0018] The utility model is further arranged such that a circulation pipe is fixed on one side of the purification box, and both ends of the circulation pipe penetrate into the interior of the purification chamber.

[0019] By adopting the above technical solution, through the arranged circulation pipe, when the pressure inside the purification chamber increases, the water at the bottom of the purification chamber will enter above the purification chamber through the circulation pipe, so that the water inside can circulate, and the gas can be purified better.

[0020] In summary, the main beneficial effects of the utility model are as follows:

[0021] The utility model solves the problem of poor gas purification effect in the prior art by arranging a purification box, a circulation pipe, a partition plate and an exhaust pipe. When the gas enters the purification chamber through the air outlet pipe, under the action of the dispersion plate, the discharged gas can be dispersed, so as to contact the water in the purification chamber. Since there are multiple partition plates, the gas can fully contact the water, and the partition plates are inclined, so the gas is discharged slowly. Moreover, the diameter of the air guide pipe is smaller than that of the air outlet pipe, and the diameter of the exhaust pipe is smaller than that of the air guide pipe, which will cause the air pressure in the purification chamber to increase. Therefore, the water at the bottom of the purification chamber will enter above the purification chamber through the circulation pipe, so that the water inside can circulate, and the discharged gas can be purified better. The purified gas enters the activated carbon through the air guide pipe, so as to purify the gas again, and finally is discharged through the exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0031] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0032] A staged gas low-nitrogen burner, as Figure 1 - Figure 7 shown, includes a low-nitrogen burner body 1. A purification box 2 is installed on one side of the low-nitrogen burner body 1. An exhaust pipe 3 is provided on one side of the low-nitrogen burner body 1, and the exhaust pipe 3 penetrates into the interior of the purification box 2. A gas staging pipe 4 is provided on one side of the low-nitrogen burner body 1. A purification chamber 21 and a filtration chamber 22 are provided inside the purification box 2. A plurality of baffles 7 are fixed inside the purification chamber 21. The burned gas enters the purification chamber 21 through the exhaust pipe 3. Under the action of the dispersion plate 9, the discharged gas can be dispersed, so as to contact the water in the purification chamber 21. Since there are multiple baffles 7, the gas can fully contact the water, and the baffles 7 are inclined, so the gas is discharged slowly. A gas duct 10 is installed on the inner wall of the filtration chamber 22, and the end of the gas duct 10 penetrates into the purification chamber 21. Activated carbon 11 is provided inside the filtration chamber 22, and an exhaust duct 6 is provided inside the filtration chamber 22.

[0033] Please refer to Figure 2 and Figure 4 , a water inlet valve 12 is provided at the top of the purification box 2, and a drain valve 8 is provided at the bottom of the purification box 2, and both the drain valve 8 and the water inlet valve 12 penetrate into the interior of the purification chamber 21. By providing the water inlet valve 12, it is convenient to add water into the purification chamber 21, and the setting of the drain valve 8 can facilitate the discharge of the water inside the purification chamber 21.

[0034] Please refer to Figure 2 , the baffle 7 is inclined, and the baffles 7 are evenly distributed inside the purification chamber 21, and every two groups of the purification chambers 21 are arranged alternately inside. The alternately inclined baffles 7 can make the gas more fully contact and react with the water inside the purification chamber 21, and the gas will not be discharged immediately.

[0035] Please refer to Figure 1 and 3 The diameter of the air duct 10 is smaller than that of the air outlet pipe 3, and the diameter of the exhaust pipe 6 is smaller than that of the air duct 10. The smaller diameter of the air duct 10 makes the gas discharge slower, so that a large amount of gas will not enter the inside of the filtration chamber 22 at the same time, and the gas purification effect is better. The smaller diameter of the exhaust pipe 6 makes the purified gas not discharged immediately in the filtration chamber 22.

[0036] Please refer to Figure 6 One side of the purification box 2 is installed with a baffle 13 through bolts, and a sealing gasket is arranged on one side of the baffle 13. The arranged baffle 13 facilitates disassembly, so that the activated carbon 11 inside the purification box 2 can be replaced conveniently. The setting of the sealing gasket ensures that there is no gas leakage inside the filtration chamber 22 due to the baffle 13.

[0037] Please refer to Figure 2 、 Figure 3 and Figure 7 A dispersion plate 9 is fixed at the bottom end of the inner wall of the purification chamber 21, and the dispersion plate 9 is conically arranged. The arranged conical dispersion plate 9 can make the gas discharged from the air outlet pipe 3 better dispersed in the purification chamber 21, so that it can better contact with water.

[0038] Please refer to Figure 2 and Figure 3 A circulation pipe 5 is fixed on one side of the purification box 2, and both ends of the circulation pipe 5 penetrate into the inside of the purification chamber 21. Through the arranged circulation pipe 5, when the pressure inside the purification chamber 21 increases, the water at the bottom of the purification chamber 21 will enter above the purification chamber 21 through the circulation pipe 5, so that the water inside circulates, and the gas can be purified better.

[0039] The working principle of the present utility model is as follows: When in use, water is added into the interior of the purification chamber 21 through the water inlet valve 12. Subsequently, the water inlet valve 12 is closed. The gas enters the low-nitrogen burner body 1 through the gas grading pipe 4. Then, the burned gas enters the purification chamber 21 through the air outlet pipe 3. Under the action of the dispersion plate 9, the discharged gas can be dispersed, so as to come into contact with the water in the purification chamber 21. Since there are multiple partition plates 7, the gas can fully contact with the water. Moreover, the partition plates 7 are inclined, so the gas is discharged slowly. In addition, the diameter of the air guide pipe 10 is smaller than that of the air outlet pipe 3, and the diameter of the exhaust pipe 6 is smaller than that of the air guide pipe 10. This will cause the air pressure in the purification chamber 21 to increase. Therefore, the water at the bottom of the purification chamber 21 will enter the upper part of the purification chamber 21 through the circulation pipe 5, enabling the water inside to circulate, and better purifying the discharged gas. The purified gas enters the filtration chamber 22 through the air guide pipe 10, and the gas is purified again by the activated carbon 11, and finally discharged through the exhaust pipe 6.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed.
