Description

Technical Field

[0001] This utility model relates to the field of high-temperature flue gaslocks, and in particular to an assembled high-temperature flue gaslock valve core. Background Technology

[0002] In high-temperature flue gas waste heat recovery scenarios such as industrial silicon smelting and waste incinerators, waste heat recovery boilers need to control the introduction of flue gas through high-temperature flue gas gate valves. However, existing gate valve core technology has significant drawbacks:

[0003] Inferior structural issues: Some manufacturers use simple gate valve cores consisting of "steel structure + thermal insulation casting material". The casting material is prone to cracking and falling off at high temperatures, causing the steel structure to be directly exposed to high-temperature flue gas, resulting in deformation and failure. Frequent shutdowns are required for replacement, which seriously affects the continuity of production.

[0004] Problems with extensive improvement methods: Some professional manufacturers delay deformation by simply increasing the thickness of the gate valve core and piling on ablative materials. Although this slightly extends the service life, it leads to a surge in material costs and excessive weight of individual units (such as those larger than 4m×4m). This not only increases the procurement pressure on enterprises, but also poses safety hazards due to the transportation of oversized components.

[0005] The aforementioned problems expose the shortcomings of traditional gate valve cores in terms of structural design, material application, and transportation and installation, and there is an urgent need for a new solution that takes into account lightweight, low cost, long service life and ease of construction. Utility Model Content

[0006] The purpose of this invention is to provide an assembled high-temperature flue gaslock valve core to solve the problems of existing technologies, such as difficulty in eliminating thermal deformation stress, easy damage to casting materials, high maintenance costs, and potential transportation safety hazards.

[0007] This utility model is achieved by the following technical solution: a modular high-temperature flue gas damper valve core, characterized in that it includes multiple gate plate assemblies, which are connected to each other as a whole by an assembly structure. Each gate plate assembly includes a heat insulation component and an installation component, wherein the heat insulation component is fixed to the installation component by bolts, and the multiple installation components are interconnected.

[0008] Furthermore, the heat insulation component includes a silicon carbide plate and an aluminum silicate ceramic fiber plate, which are arranged sequentially from the outside to the inside, and are fixed to the mounting component by connecting bolts.

[0009] Furthermore, the mounting assembly includes a mounting plate and a mounting bracket. The outer side of the mounting plate is connected to the heat insulation assembly, and the inner side is connected to the mounting bracket. The mounting bracket is welded to the mounting plate, and the mounting bracket includes several steel pipes.

[0010] Furthermore, the mounting frame includes two sets of steel pipes, each set of steel pipes is welded in parallel and set at both ends of the mounting plate, so that the edge of the mounting frame and the edge of the mounting plate are on the same plane. When the two mounting components are spliced ​​together, the two sets of steel pipes at the edge are arranged in a rectangular layout.

[0011] Furthermore, a sealing strip is provided at the center of the four steel pipes at the edge of the two mounting components, and an installation groove is provided at the splice joint on the side of the aluminum silicate ceramic fiber board. A sealing strip is also provided in the installation groove, and the two sealing strips achieve the sealing of the splice joint.

[0012] Furthermore, the mounting assembly also includes a connecting rod, which is perpendicular to the steel pipe on the mounting frame and passes through the steel pipe on the mounting frame to connect multiple mounting assemblies in series to form an integral structure.

[0013] Furthermore, several reinforcing bars are installed between the mounting brackets to improve the stability of the mounting components.

[0014] The advantages of the assembled high-temperature flue gas damper valve core described in this utility model include:

[0015] Modular assembly: After being heated, the modular structure allows for non-rigid connections between modules in the horizontal direction, thus eliminating thermal deformation stress in this direction. Furthermore, the modular components can be disassembled for processing and transportation, reducing the risks associated with transporting oversized units and facilitating rapid on-site installation to adapt to complex working conditions.

[0016] Lightweighting and cost reduction: Optimize structural design and use high-performance high-temperature resistant materials to reduce material stacking and reduce unit weight and manufacturing costs by more than 30%.

[0017] Long lifespan and reliability: Through a layered protective structure (such as a combination of a thermal shock resistant composite layer and a thermal insulation layer), high-temperature ablation is slowed down, and the service life is more than twice that of traditional products.

[0018] Convenience of operation and maintenance: When a part is damaged, the module can be replaced individually, avoiding the scrapping of the whole module and further reducing maintenance costs.

[0019] Safety and economy: Balancing lightweight design, low cost, and high reliability, it provides efficient protection for enterprises' energy conservation, emission reduction, and safe production. Attached Figure Description
