The utility model discloses a combined system for sealing a water cooling structure. The combined system comprises a front arch water cooling wall, a rear arch water cooling wall, a flue side water cooling wall, expansion joints, a heavy furnace wall and an incinerator protection plate, and the expansion joints are installed on the upper portion and the lower portion of a header on the lower portion of the flue side water cooling wall; the two ends of a flue side water cooling wall, the front arch water cooling wall, the rear arch water cooling wall and the incinerator protection plate are connected through a masonry structure, and a heavy furnace wall with enough expansion gaps is manufactured. The combined system for sealing the water cooling structure has good sealing performance, sealing and smoke leakage are avoided during operation, and downward, forward and backward expansion of the water cooling wall can be well absorbed during operation; the conditions that the water cooling wall is pulled to be cracked and exploded due to the fact that expansion cannot be achieved are prevented, and safe and stable operation of the boiler is better guaranteed.

Description

Technical Field

[0001] The present application belongs to the technical field of boilers, and in particular relates to a combined system for sealing a water-cooling structure. Background Art

[0002] At present, with the development of economy and society, the demand for high calorific value and large capacity garbage treatment is becoming increasingly strong, and there is also a demand for co-burning of industrial solid waste. Therefore, a water-cooled structure with front and rear water-cooled arches and water-cooled walls on both sides in the furnace combustion area has become a necessary choice. The furnace surface temperature is low and it is not easy to get coke. The water-cooled walls on both sides replace the air-cooled walls of the insulated furnace, which completely prevents the occurrence of furnace wall collapse and shutdown, and ensures long-term operation of the boiler. After adopting the water-cooled structure, sealing here becomes the key. Therefore, how to ensure the quality of the sealing here is a difficult problem that urgently needs to be solved. Utility Model Content

[0003] The utility model aims to solve the technical problem of how to achieve good sealing after a boiler adopts a water cooling structure, and provides a combined system for sealing the water cooling structure.

[0004] In order to achieve the above application purpose, the technical solution adopted in this application is as follows:

[0005] The embodiment of the present application provides a combined system for sealing a water-cooled structure, including: a front arch water-cooled wall, a rear arch water-cooled wall, a flue side water-cooled wall, an expansion joint, a heavy furnace wall, and an incinerator guard plate;

[0006] The expansion joint is arranged at the upper and lower parts of the lower header of the water-cooled wall on the flue side to ensure the normal expansion of the water-cooled wall on the flue side;

[0007] The two ends of a flue side water-cooled wall, the front arch water-cooled wall and the rear arch water-cooled wall connected to the incinerator guard plate are heavy furnace walls with expansion joints.

[0008] Optionally, the heavy furnace wall is a masonry structure.

[0009] Compared with the prior art, the beneficial effects of the embodiments of the present application are:

[0010] The embodiment of the present application provides a combined system for sealing a water-cooled structure, which has good sealing performance, realizes sealing without smoke leakage during operation, and absorbs the downward, forward and backward expansion of the water-cooled wall well through energy-saving expansion during operation; prevents the water-cooled wall from being torn or burst due to the inability to expand, thereby better ensuring the safe and stable operation of the boiler.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
