Description

Technical Field

[0001] The present invention relates to the technical field of energy savers, and in particular to an energy saver for a gas boiler. Background Art

[0002] In industrial production, industrial boilers, as important equipment for energy conversion, are widely used in power generation, heating, and steam and hot water supply in process flows. Among them, steam boilers are mainly used for power generation or to provide high-pressure steam to various industrial processes, while gas boilers, especially waste heat boilers, focus on recovering and utilizing waste heat generated in various industrial production processes to improve energy efficiency and reduce environmental pollution. One of the core components of a waste heat boiler is the boiler economizer, which was originally designed to capture and recycle the heat energy carried by the high-temperature flue gas generated during the boiler combustion process. Through the energy conversion structure within the economizer, the high-temperature flue gas is cooled, and the released heat is transferred to the boiler's feed water system, thereby preheating the feed water and improving the overall thermal efficiency of the boiler. This process not only reduces the direct emission loss of heat, but also promotes the recycling of resources, which is in line with the green development trend of modern industry.

[0003] However, the boiler economizers in the prior art have significant deficiencies in actual operation. Specifically, when the high-temperature flue gas enters the economizer, due to its fast flow speed and the relatively direct path design, the residence time of the flue gas inside the economizer is relatively short. This limitation directly affects the heat exchange efficiency between the energy conversion structure and the flue gas in the economizer, so that a large amount of heat energy cannot be effectively captured and transferred to the feed water. In addition, due to the short residence time of the flue gas in the economizer, the energy conversion structure cannot fully absorb the heat energy in the flue gas, resulting in limited heat recovery, which in turn limits the increase in the boiler feed water temperature. A lower feed water temperature not only reduces the thermal efficiency of the boiler, but may also affect the stable operation of the boiler and the quality of the output steam, which has an adverse effect on subsequent production processes.

[0004] The Chinese invention patent with publication number CN117490053A discloses an economizer for a gas boiler. A sealing member is installed in the shell. When the smoke enters the shell, the sealing member cooperates to prevent the smoke from being discharged to the outside, thereby increasing the time it stays in the shell and heating the water in the interlayer. After a period of closure, the sealing member is released by the release member, allowing the smoke to be discharged from the outlet. The device absorbs more heat from the flue gas. However, it requires the use of a drive structure such as an electric push rod, which increases energy consumption. Moreover, when the electric push rod fails, the energy conversion structure in the economizer cannot be used directly, and the stability is not high.

[0005] In view of this, the present invention proposes an economizer for a gas boiler to remedy and improve the deficiencies of the prior art. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting the partition component 1 and the partition component 2, a flue gas flow passage with multiple curved sections is formed in the accommodating chamber. The flue gas cannot flow in a straight line to quickly leave the accommodating chamber through the air outlet, which prolongs the time the flue gas stays in the economizer. As a result, the heat exchanger structure inside the economizer exchanges more heat from the flue gas, which increases the temperature of the heat returned to the boiler and the feed water temperature of the boiler. In addition, there is no need to use a driving structure such as a motor, which has a simple structure, low cost, high reliability, and low difficulty in maintenance and replacement. The inclined arrangement of the inclined plate 1 and the inclined plate 2 will also block part of the flue gas, reducing the flow rate of the flue gas, further prolonging the time the flue gas stays in the economizer, and ultimately increasing the feed water temperature of the boiler. (2) The arrangement of filter plate 1 and filter plate 2 serves to block dust in the flue gas, facilitating subsequent flue gas discharge and improving the practicality of the present application. The top of filter plate 1 is inserted into slot 1 to fix filter plate 1, so that filter plate 1 can stably block dust in the flue gas. The blocking structure 1 can be folded or bent to block only one side of filter plate 1 without blocking filter hole 1. Filter plate 1 is an elastic plate, and each filter hole 1 is arranged in a square array, especially each filter hole 1 distributed at intervals along the vertical direction. At this time, for a column of filter holes 1 distributed vertically, by inserting a rod into the lowest filter hole and moving it upward, the dust in this column of filter holes 1 can be pushed out, making it convenient to remove filter plate 1 for dust cleaning. (3) By setting up the connecting mechanism, each partition mechanism 1 and each partition mechanism 2 can support each other. At this time, it is not necessary to connect each partition mechanism 1 and each partition mechanism 2 to the wall of the accommodating chamber. The base is composed of a bottom plate, a top plate, a front plate, a back plate and two side plates. It is convenient to remove the partition component 1 and the partition component 2. When the base is damaged, only part of it needs to be replaced without replacing the entire base. It is also convenient to clean the water storage chamber. When the partition component 1 and the partition component 2 are set in the base, they generally fit the top wall and bottom wall on the inner side of the base to avoid providing a straight flow path for the smoke. When the connecting mechanism is not set up, such a setting can also play the role of clamping and fixing the partition component 1 and the partition component 2. BRIEF DESCRIPTION OF THE DRAWINGS

Summary 3: Compared with the prior art, a connecting mechanism 6 is provided between any two adjacent partition mechanisms 1 41 and between any two adjacent partition mechanisms 2 51, so that each partition mechanism 1 41 and each partition mechanism 2 51 can support each other. At this time, there is no need to connect each partition mechanism 1 41 and each partition mechanism 2 51 to the wall of the accommodating chamber 11, and the base is composed of a bottom plate 14, a top plate 15, a front plate 16, a back plate 17 and two side plates 18. It is convenient to remove the partition component 1 4 and the partition component 2 5. When the base is damaged, only part of it needs to be replaced without replacing the entire part. It is also convenient to clean the water storage chamber.

[0022] The following is the working process and principle of the above embodiment: The initial state is as follows: the bottom plate 14, the top plate 15, the front plate 16, the back plate 17 and the two side plates 18 constitute the shell 1 and form the accommodating chamber 11 and the water storage chamber. The water inlet pipe 2 is connected to a water injection device such as a faucet, and the water outlet pipe 3 remains closed. Then water is injected into the water storage chamber, and the water fills the water storage sub-chamber 1, water storage sub-chamber 2, water storage sub-chamber 3, water storage sub-chamber 4 171, and water storage sub-chamber 5 181.

[0023] The working steps are as follows: The flue gas is injected into the accommodating chamber 11 through the air inlet. When the partition component 14 and the partition component 2 5 are not provided, the flue gas can flow in a straight line and leave the accommodating chamber 11 through the air outlet 13. After the partition component 14 and the partition component 2 5 are provided, a flue gas flow passage with multiple curved sections is formed in the accommodating chamber 11. The flue gas cannot flow in a straight line to quickly leave the accommodating chamber 11 through the air outlet 13, which prolongs the time the flue gas stays in the economizer, thereby making the energy conversion structure inside the economizer exchange more heat for the flue gas, thereby increasing the temperature of the heat returned to the boiler and the feed water temperature of the boiler, and does not require a driving structure such as a motor, so the structure is simple, the cost is reduced, the reliability is high, and the difficulty of maintenance and replacement is also low. When the flue gas flows in the curved flow passage, it is affected by the cavity wall of the accommodating chamber 11, the blocking structure 1 4 13, the blocking structure 2, and the blocking structure The smoke is restricted and guided by the three-block structure 513 and the four-blocking structure, and is forced to flow along the curved flow channel. During the flow, it touches the inclined plate 1 7 and the two-blocking plate 8. The inclined arrangement of the inclined plate 1 7 and the two-blocking plate 8 will also block part of the smoke, thereby reducing the flow velocity of the smoke, further prolonging the time the smoke stays in the economizer, and ultimately increasing the feed water temperature of the boiler. The sealing structure 1 413, the two-blocking structure, the three-blocking structure 513 and the four-blocking structure can be set as blocking baffles, and each blocking baffle is fixed by the fixed plate 1 9 or the fixed plate 2 10. Taking the fixing plate 1 9 for fixing the blocking structure 1 413 as an example, the fixed plate 1 9 is inserted into a mounting slot 3 414 and a mounting slot 1 4112 to fix the blocking structure 1 413. The blocking structure 1 413 can be quickly replaced and can be separated from the connecting plate 1 411, thereby improving the flexibility of structural utilization.

[0024] The arrangement of the filter plate 1 412 and the filter plate 2 512 serves to block the dust in the smoke, making it easier to discharge the smoke later and improving the practicality of the present application. The following description is based on the filter plate 1 412. The top of the filter plate 1 412 is inserted into the card slot 1 4111 to fix the filter plate 1 412 so that the filter plate 1 412 can stably block the dust in the smoke. When the filter plate 1 412 is not in use, the filter plate 1 412 is clamped and blocked by the blocking structure 1 413 and the blocking structure 2. When the filter plate 1 412 is used, the filter plate 1 412 is clamped and blocked by the blocking structure 1 413 and the blocking structure 2. When the filter plate 1 412 is used, the blocking structure 1 413 and the blocking structure 2 need to be moved, and the blocking structure 1 413 and the blocking structure 2 can be quickly separated from the connecting plate 1 411, so they can be quickly taken out, improving the flexibility, convenience and practicality of use. The blocking structure 1 413 and the blocking structure 2 can be set as a blocking film. The blocking structure 1 413 is used as an example. After the blocking structure 1 413 is set as a blocking film, it is relatively soft. When using the filter plate 1 412, first separate the fixing plate 1 9 and the corresponding trough structures, and then translate the blocking structure 1 413 and the blocking structure 2 into a blocking film. The blocking structure 413 is then fixed to one of the fixing plates 9 again, and another fixing plate 9 is fixed by the mounting groove 5 110 on the fixing plate 3 100, thereby achieving the fixed blocking structure 413 after the transfer. At this time, the blocking structure 413 stably blocks the area on one side of the filter plate 412, so that the smoke can only flow through the several filter holes 4121 on the filter plate 412. Since the blocking structure 413 is relatively soft after being set as a blocking film, the blocking structure 413 can be folded or The curved setting will only block the area on one side of the filter plate 412 but not the filter hole 4121. The filter plate 412 is an elastic plate, and the filter holes 4121 are arranged in a square array, especially the filter holes 4121 distributed at intervals along the vertical direction. At this time, for a column of filter holes 4121 distributed vertically, the dust in this column of filter holes 4121 can be pushed out by inserting a rod into the lowest filter hole 4121 and moving it upward, thereby facilitating the removal of the filter plate 412 for dust cleaning.

[0025] A connecting mechanism 6 is provided between any two adjacent partition mechanisms 1 41 and any two adjacent partition mechanisms 2 51, so that each partition mechanism 1 41 and each partition mechanism 2 51 can support each other. At this time, there is no need to connect each partition mechanism 1 41 and each partition mechanism 2 51 to the wall of the accommodating chamber 11, and the base is composed of a bottom plate 14, a top plate 15, a front plate 16, a back plate 17 and two side plates 18. It is convenient to remove the partition component 1 4 and the partition component 2 5. When the base is damaged, only part of it needs to be replaced without replacing the entire part. It is also convenient to clean the water storage chamber. When the partition component 1 4 and the partition component 2 5 are arranged in the base, the two generally fit the top and bottom walls on the inner side of the base to avoid providing a straight flow path for the smoke. When the connecting mechanism 6 is not provided, such an arrangement can also serve to clamp and fix the partition component 1 4 and the partition component 2 5.
