Double Vented Masonry Wall

Abstract

The invention relates to a double-layer ventilation masonry wall, which is used for the inner wall or outer wall of an industrial building, and comprises a first wall body, a second wall body, a ventilation air layer, a ventilation pipe, a blower fan and an exhaust fan. The ventilation air layer is arranged between the first wall body and the second wall body. The ventilation duct is arranged in the ventilation air layer. The blower is connected to the ventilation duct, and is used for sucking an indoor / outdoor air into the ventilation duct. The exhaust fan is connected to the terminal of the ventilation duct, and is used for exhausting the gas sucked into the ventilation duct to the outdoor / indoor. The invention can not only meet the requirement of discharging dangerous gas, but also can deliver fresh air to rooms that need fresh air, and can also reserve space for the laying of other pipelines, thereby not occupying the production space, and avoiding rainwater pipes, which can provide a complete system for production. , flexible and free space.

Description

technical field [0001] The invention relates to a building wall structure, in particular to a double-layer ventilation masonry wall which can solve the problem of ventilation. Background technique [0002] At present, in domestic industrial buildings, when the production heat source or radiant heating heat source is a gas lighter than air (such as natural gas), it is relatively easy to solve the problems encountered in the engineering design of plant ventilation and fire protection, which can be installed on the roof or Use external windows or install ventilators on the external wall to solve the problem. [0003] When the heat source gas is heavier than air (such as propane), the situation is more complicated. These gases are heavier than air and are not volatile, and gas leakage and insufficient combustion will inevitably occur during production and use. If no measures are taken for it, the gas It will gradually accumulate near the ground of the factory building. When it ...

Problems solved by technology

[0003] When the heat source gas is heavier than air (such as propane), the situation is more complicated. These gases are heavier than air and are not volatile, and gas leakage and insufficient combustion will inevitably occur during production and use. If no measures are taken for it, the gas It will gradually accumulate near the ground of the plant, and when it accumulates to a certain concentration, there will be a danger of combustion and explosion when it encounters an open flame

[0004] At present, the commonly used solution is to exhaust the factory building with surface-mounted suction pipes indoors. The disadvantages of this are: 1. There will be many suction pipes in the factory building, which will affect the usable space of the factory building; 2. The pipes are all exposed in the workshop The side wall has a serious conflict with the rainwater pipe; 3. There are many air outlets connected to the outside, which will damage the overall aesthetic effect of the factory building

[0005] On the other hand, there are mainly two types of double-layer walls in China, one is double-layer curtain wall, the outside is generally glass curtain wall or metal plate curtain wall, the middle is an air layer, and the inner layer is generally glass curtain wall, stone curtain wall or masonry wall , the cost of this kind of wall is high, and it is rarely used in factories in China, and it is difficult to install equipment between double-layer curtain walls, which cannot solve the problem of timely discharge of harmful gases

The other is a composite sandwich wall, with masonry walls on both sides and an insulation layer (such as extruded polystyrene board) in the middle, combined to form an integral composite wall. This kind of wall has better thermal insulation performance than ordinary masonry walls, but it cannot solve the problem. ventilation problem
