Description

Technical Field

[0001] This utility model relates to the field of thermal storage heating furnace technology, and more specifically to an energy-saving thermal storage natural gas heating furnace. Background Technology

[0002] High-temperature heat treatment is an indispensable core process in many industrial fields such as metallurgy, machinery, chemical industry, and building materials. Such processes usually require materials to be continuously heated to hundreds or even thousands of degrees Celsius, which consumes a lot of energy and is a veritable energy consumer. With the continuous rise in global energy costs and the in-depth promotion of the "dual carbon" strategic goal, energy conservation and emission reduction of industrial furnaces have become an urgent need and a major technical challenge for the sustainable development of the industry.

[0003] For a long time, natural gas has been one of the main fuels widely used in the field of industrial heating due to its advantages such as being clean, efficient, easy to control and having environmentally friendly combustion products. Nowadays, the regenerative natural gas heating furnace system combines burners and regenerators in pairs and switches between them periodically under precise timing control to achieve energy saving.

[0004] When using modern regenerative natural gas heaters, natural gas needs to be mixed with air before being introduced into the furnace. However, if the gas is not mixed evenly, the combustion efficiency of the natural gas will decrease, resulting in incomplete combustion and wasting resources. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy-saving thermal storage natural gas heater to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an energy-saving, heat-storing natural gas heater, comprising a heater body, a heater sealing door fixedly connected to the side of the heater body, a flue pipe fixedly connected to the top of the heater body, an inlet pipe fixedly connected to the side of the heater body away from the flue pipe, a second mixing mechanism fixedly connected to the side of the inlet pipe away from the heater body, a natural gas pipe fixedly connected to the side of the second mixing mechanism away from the inlet pipe, and a first mixing mechanism fixedly connected to the side of the natural gas pipe; the first mixing mechanism includes a first blower that can provide gas, a first gas pipe fixedly connected to the side of the first blower, a sealing pipe fixedly connected to the bottom end of the first gas pipe, the sealing pipe being located on the side of the natural gas pipe and fixedly connected to the natural gas pipe, and a through hole being opened on the side of the natural gas pipe, the through hole being located inside the sealing pipe.

[0007] Furthermore, the natural gas pipe passes through the first mixing mechanism and is connected to the second mixing mechanism, which is connected to the interior of the heating furnace body through an inlet pipe.

[0008] Furthermore, the natural gas pipe has three sets of through holes on its side, with six through holes in each set. The sealed pipe is sealed to the sides of the natural gas pipe, and a space for gas to pass through is provided inside the sealed pipe.

[0009] Furthermore, the second mixing mechanism includes a second blower that provides air, a second gas pipe that is fixedly connected to the side of the second blower, a gas chamber that is fixedly connected to the side of the second gas pipe away from the second blower, and a sealing cap that is fixedly connected to the side of the gas chamber away from the inlet pipe, the sealing cap being in communication with a natural gas pipe.

[0010] Furthermore, two connecting plates are fixedly connected to the top of the gas chamber, and a rotating shaft is fixedly connected to the sides of the bottom of the two connecting plates that are close to each other. A surrounding cylinder is movably sleeved on the side of the rotating shaft, and a blade assembly is fixedly connected to the side of the surrounding cylinder.

[0011] Furthermore, the blade assembly is located inside the gas chamber on the side near the inlet pipe, and the second gas pipe is located on the side of the blade assembly away from the inlet pipe, and the gas chamber is in communication with the inlet pipe.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model includes a first blower, a first gas pipe, a sealed pipe, and through holes. Natural gas enters and circulates through the natural gas pipe. At this time, the first blower introduces air into the sealed pipe through the first gas pipe. The air in the sealed pipe enters the natural gas pipe through through holes opened on the side of the natural gas pipe. There are three sets of through holes to improve the mixing effect, so that the gas and natural gas are fully mixed in the natural gas pipe, improving the combustion effect and avoiding natural gas waste.

[0014] 2. This utility model comprises a gas chamber, a second gas pipe, and a second blower. Gas mixed in the natural gas pipe enters the gas chamber, and a second blower blows outside air into the gas chamber through the second gas pipe. The gas in the natural gas pipe and the gas entering through the second gas pipe enter the gas chamber simultaneously and flow into the inlet pipe. This flow drives the blade assembly to rotate, further mixing the air entering through the second gas pipe with the mixed gas entering through the natural gas pipe. This ensures thorough mixing of the natural gas and air, allowing for complete combustion of the natural gas within the heating furnace body. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figure 1 and Figure 2 This utility model provides an energy-saving and heat-storage natural gas heater, including a heater body 1, a heater sealing door 2 fixedly connected to the side of the heater body 1, a flue pipe 3 fixedly connected to the top of the heater body 1, an inlet pipe 7 fixedly connected to the side of the heater body 1 away from the flue pipe 3, a second mixing mechanism 6 fixedly connected to the side of the inlet pipe 7 away from the heater body 1, a natural gas pipe 4 fixedly connected to the side of the second mixing mechanism 6 away from the inlet pipe 7, a first mixing mechanism 5 fixedly connected to the side of the natural gas pipe 4, the natural gas pipe 4 passing through the first mixing mechanism 5 and communicating with the second mixing mechanism 6, and the second mixing mechanism 6 communicating with the interior of the heater body 1 through the inlet pipe 7.

[0022] In this embodiment, the natural gas in the natural gas pipe 4 is mixed with the outside air through the first mixing mechanism 5 and the second mixing mechanism 6, and then enters the heating furnace body 1 through the inlet pipe 7. When the fully mixed gas is burned, it can be fully burned, thereby avoiding waste of natural gas and achieving the effect of energy saving.

[0023] Reference Figure 3 The first mixing mechanism 5 includes a first blower 501 that can provide gas. A first gas pipe 502 is fixedly connected to the side of the first blower 501. A sealing pipe 503 is fixedly connected to the bottom end of the first gas pipe 502. The sealing pipe 503 is located on the side of the natural gas pipe 4 and is fixedly connected to the natural gas pipe 4. A through hole 504 is opened on the side of the natural gas pipe 4. The through hole 504 is located inside the sealing pipe 503. Three sets of through holes 504 are opened on the side of the natural gas pipe 4. Each set of through holes 504 contains six through holes 504. The sealing pipe 503 is sealed to the sides of the natural gas pipe 4 on both sides. A space for gas to pass through is opened inside the sealing pipe 503.

[0024] In this embodiment, the gas in the first gas pipe 502 enters the sealed pipe 503. The two ends of the sealed pipe 503 are sealed, allowing the gas to flow in the space of the gas chamber 603. The gas then enters the natural gas pipe 4 through the three sets of through holes 504 on the side of the natural gas pipe 4. The air and the natural gas in the natural gas pipe 4 are mixed multiple times to improve the mixing effect. The three sets of through holes 504 ensure that the air can enter in stages, thus making the mixing more uniform.

[0025] Reference Figure 4 The second mixing mechanism 6 includes a second blower 601 that provides air. A second gas pipe 602 is fixedly connected to the side of the second blower 601. A gas chamber 603 is fixedly connected to the side of the second gas pipe 602 away from the second blower 601. A sealing cover 604 is fixedly connected to the side of the gas chamber 603 away from the inlet pipe 7. The sealing cover 604 is connected to the natural gas pipe 4. Two connecting plates 605 are fixedly connected to the top of the gas chamber 603. A rotating shaft 606 is fixedly connected to the side of the bottom of the two connecting plates 605 that are close to each other. A surrounding cylinder 607 is movably sleeved on the side of the rotating shaft 606. A blade assembly 608 is fixedly connected to the side of the surrounding cylinder 607. The blade assembly 608 is located inside the gas chamber 603 on the side close to the inlet pipe 7. The second gas pipe 602 is located on the side of the blade assembly 608 away from the inlet pipe 7. The gas chamber 603 is connected to the inlet pipe 7.

[0026] In this embodiment, the gas in the second gas pipe 602 enters the gas chamber 603. At this time, the mixed gas in the natural gas pipe 4 and the air in the second gas pipe 602 flow in the gas chamber 603. When the gas flows, it passes through the blade assembly 608. When the gas passes through the blade assembly 608, it drives the blade assembly 608 to rotate. When the blade assembly 608 rotates, the mixed gas in the natural gas pipe 4 and the gas in the second gas pipe 602 are mixed again. The blade assembly 608 is located in the gas chamber 603 on the side close to the inlet pipe 7, and the second gas pipe 602 is located on the side of the blade assembly 608 away from the inlet pipe 7. This ensures that the gas in the second gas pipe 602 passes through the blade assembly 608, guaranteeing the mixing effect and preventing the gas in the second gas pipe 602 from being discharged into the heating furnace body 1 from the inlet pipe 7 without being mixed.

[0027] The working principle of this utility model is as follows: During combustion, natural gas enters through the natural gas pipe 4. When the natural gas enters the natural gas pipe 4, the connecting plate 605 is activated, which introduces gas into the first gas pipe 502. The gas in the first gas pipe 502 enters the sealed pipe 503. The two ends of the sealed pipe 503 are sealed, allowing the gas to enter the natural gas pipe 4 through the three sets of through holes 504 on the side of the natural gas pipe 4. The air and the natural gas in the natural gas pipe 4 are mixed multiple times to improve the mixing effect.

[0028] After being mixed in natural gas pipe 4, the gas enters gas chamber 603. At this time, the second blower 601 starts and causes the gas to enter the second gas pipe 602. The gas in the second gas pipe 602 then enters gas chamber 603. The mixed gas in natural gas pipe 4 and the air in the second gas pipe 602 flow in gas chamber 603. As the gas flows, it passes through blade assembly 608. When the gas passes through blade assembly 608, it drives blade assembly 608 to rotate. When blade assembly 608 rotates, the mixed gas in natural gas pipe 4 and the gas in second gas pipe 602 are mixed again. After mixing, the gas enters the heating furnace body 1 through inlet pipe 7. The fully mixed air and natural gas are fully combusted in the heating furnace body 1 and then discharged through exhaust pipe 3, ensuring that the natural gas can be fully combusted.

[0029] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
