Abstract

This utility model discloses a sealing structure for the HVAC exhaust vents of the exterior curtain wall of a waste-to-energy plant, relating to the field of building sealing engineering technology. The utility model comprises a three-layer structure: a masonry wall layer with an axial flow fan vent, an aluminum alloy rainproof louver on the outside, and a C20 concrete reinforcing frame around the vent; a metal panel curtain wall layer with an equally sized metal grille vent directly opposite the masonry vent, the air gap between the curtain wall and the masonry wall sealed with a 1.5mm aluminum plate; and a secondary sealing layer filled with ≥100mm rock wool around the vent's frame beams and columns. This utility model effectively solves the odor diffusion problem and improves the indoor air environment of the waste-to-energy plant by aligning the HVAC axial flow fan vents with the curtain wall vents, using a metal plate to seal the air gap between them initially, and using rock wool to seal the surrounding frame beams and columns secondaryly.

Description

Technical Field

[0001] This utility model belongs to the field of building sealing engineering technology, specifically relating to the odor-proof structure of the HVAC exhaust vent of the exterior curtain wall of a waste incineration power plant. Background Technology

[0002] In waste-to-energy plants, according to HVAC requirements, multiple axial flow fan exhaust vents of varying sizes need to be installed on the exterior walls of the plant. These vents are typically constructed by the civil engineering unit initially, followed by a secondary construction by the curtain wall unit. However, inconsistencies in the positioning and size of the vents between the construction and curtain wall units directly resulted in insufficient ventilation.

[0003] Even more seriously, the odors produced by the incinerator, after being discharged through openings in the masonry walls, diffuse and circulate in the air layer between the masonry walls and the metal panel curtain wall, thus causing odors throughout the entire incinerator. Furthermore, the source of these odors is difficult to locate, severely impacting the air quality for visitors, office workers, and operators within the incinerator.

[0004] Therefore, we propose a sealing structure for the HVAC vent openings of the exterior wall of a waste incineration power plant. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing structure for the HVAC exhaust vent of the exterior wall of a waste incineration power plant, which prevents the spread of odor through a primary sealing (aluminum plate sealing the cavity) and a secondary sealing (rock wool filling the beams and columns).

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sealing structure for the HVAC exhaust vent opening of the exterior curtain wall of a waste incineration power plant, comprising:

[0008] An axial flow fan opening is made in the masonry wall;

[0009] Aluminum alloy rainproof louvers installed on the outside of masonry walls;

[0010] A metal panel curtain wall is installed on the outside of the masonry wall, with a metal grid opening of the same size facing the axial flow fan opening.

[0011] A 1.5mm thick aluminum plate sealing layer is used to fill the air gap between the metal panel curtain wall and the masonry wall.

[0012] The secondary sealing layer of rock wool filling the frame beams and columns around the axial flow fan opening has a thickness of not less than 100mm.

[0013] In one embodiment, the axial flow fan opening of the masonry wall is surrounded by a C20 concrete reinforcing frame, and four Φ10 steel bars are arranged inside at 200mm intervals.

[0014] In one embodiment, the metal grille opening is composed of 50mm×50mm×5mm metal grilles, which are arranged horizontally or vertically.

[0015] In one embodiment, the aluminum plate sealing layer connects the metal panel curtain wall and the masonry wall through a folded interlocking method, forming a continuous airtight interface.

[0016] In one embodiment, the filling density of the rock wool secondary sealing layer is ≥90%, and it covers the entire area of ​​the joint between the frame beams / columns and the opening.

[0017] In one embodiment, the distance between the aluminum alloy rainproof louver and the metal grille opening is 100mm, forming a direct gas exhaust channel.

[0018] This utility model has the following beneficial effects:

[0019] This invention avoids the problem of poor exhaust caused by mismatched openings by aligning the openings of the axial flow fan in the building's HVAC system with the openings in the curtain wall. Simultaneously, a 1.5mm thick aluminum plate is used to seal the air layer between the metal panel and the masonry wall opening, and rock wool with a thickness of at least 100mm is used to seal the frame beams and columns around the axial flow fan opening. This effectively prevents the odor generated in the incinerator from diffusing and circulating in the air layer between the masonry wall and the metal panel curtain wall, preventing the odor from entering the incinerator interior. This significantly improves the indoor air quality of the incinerator, providing better conditions for indoor visits, offices, and operations.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
