Salt water experiment simulation system used for building ventilation and smoke discharge experiments and using method thereof

Abstract

The invention relates to a salt water experiment simulation system used for building ventilation and smoke discharge experiments and a using method thereof. The system uses movement and diffusion of salt water in clear water to simulate spreading and heat transfer of smoke in the air and comprises an experimental clear water tank, a model, a high-level salt water tank, a high-level clear water tank, a salt water storage tank, a clear water storage tank, a model drain pipe, a solar evaporation concentrator and a drain tank, wherein the experimental clear water tank is used for simulating the outdoor natural air supplement environment; the model is put in the experimental clear water tank and is used for simulating the space of tall buildings; the high-level salt water tank is connected with the model by a salt water injection pipe; the high-level clear water tank is connected with the model by a clear water injection pipe of the model; the salt water storage tank is connected with the high-level salt water tank; the clear water storage tank is connected with the high-level clear water tank; the model drain pipe is connected at the lower end of the model; the solar evaporation concentrator and the drain tank are simultaneously connected with the model drain pipe. Compared with the prior art, the system has a simple structure, is easy to manufacture, can carry out experimental simulation on ventilation and smoke discharge effects of different spaces and has higher simulation accuracy; the drained water can be recycled.

Description

technical field [0001] The invention relates to the field of ventilation and smoke prevention and exhaust, in particular to a salt water experiment simulation system and use method for building ventilation and smoke exhaust experiments, which are used to provide experimental basis for the design of ventilation and smoke prevention in large spaces. Background technique [0002] With the advancement of construction technology and the improvement of people's living standards, buildings are constantly developing towards high, large and diversified functions. In modern buildings, in order to meet the growing pursuit of people's quality of life, various types of atriums and other tall spaces continue to emerge in buildings, which put great pressure on the ventilation and smoke prevention of buildings. [0003] In the current "Code for Fire Protection Design of Buildings" GB50016, the regulations on the amount of mechanical smoke exhaust in tall spaces such as atriums still only co...
