Double ventilation masonry wall

Abstract

The invention relates to a double ventilation masonry wall applied to interior walls or exterior walls for industrial buildings. The double ventilation masonry wall comprises a first wall, a second wall, a ventilation air layer, a ventilation pipeline, blowers and an exhaust fan. The ventilation layer is disposed between the first wall and the second wall; the ventilation pipeline is disposed in the ventilation air layer. The blowers are connected to the ventilation pipeline and are used for indoor / outdoor air into the ventilation pipeline. The exhaust fan is connected to a terminal of the ventilation pipeline and used for discharging the air sucked into the ventilation pipeline, to the outdoor / indoor. The double ventilation masonry wall has the advantages that the requirement for emission of dangerous gases is met, fresh air can be provided for a room needing the fresh air, space is reserved for laying other pipelines, production space is saved, a rain pipeline is avoided, and complete, flexible and free space is provided for production.

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
