Abstract
The utility model is a kind of gas diffusion test confined chamber of adjustable meteorologic parameter, by gas transmission pipeline, and floor heating capillary network, airing hole, exhaust fan, humidifying spraying nozzle, heating water pipe, the compositions such as humidification water pipe.Whole device can simulate the gas diffusion test in real space in the changeable space of classics.By the key monitoring point of (the adjustment change of epidemic disaster, wind speed and indoor particulate matter, the adjustment etc. of leak export model) under finding each space environment series of experiments condition, can be the number of times reducing gas leakage diffusion test, also for the reasonable Arrangement of the respective sensor of gas leakage diffusion provides reference, simultaneously, according to flue gas diffusion carry out safe distance preresearch estimates, security protection mode and the safe distance of test point personnel can also be determined.
Description
Technical field
The utility model relates to a kind of confined chamber of Experiment of Gas Proliferation, be utilize the meteorologic parameter of its internal adjustable to simulate in real space gas diffusion experimental provision.
Background technology
Along with the raising of the degree of depth degree of research, the requirement of people to experimental result accuracy is more and more higher.But existing similarity theory is not enough to simulate the relatively real situation of experiment.So increasing experiment is to carry out close to true or actual proportions, to avoid the interference of other factors.
Like this, really comparatively accurate result can be measured more accurately, but, for some large-scale experiments or special experiment, such a simulated cost is too high, wastes time and energy, and is difficult to again to accomplish exhaustive, be difficult to the process controlling whole experiment, be difficult to obtain gratifying result.
Therefore, need a kind of experimental provision, while carrying out the Experiment of Gas Proliferation in some changeable space of specific typical case, experimentation, Control experiment cost can be simplified, good control can be obtained again and draw comparatively accurate result.
Utility model content
The utility model provides a kind of Novel closed room, to utilize in confined chamber adjustable meteorologic parameter to simulate the changeable space of specific typical case, with the process of gas diffusion in the test space.
The utility model solves the technical scheme that its technical matters adopts:
One, the adjustment of temperature and realization: at confined chamber top, bottom is provided with capillary network floor heating system, and heat (cold) water flows through inside capillary network, regulates internal temperature by radiation effects.
Two, the adjustable and realization of humidity: arrange humidifying spraying nozzle bottom confined chamber left side plate, shower nozzle is by spraying to regulate interior humidity
Three, the regulation and control of wind speed and realization: wind speed by the outside exhausting of set 4 row's stepless time adjustment blower fan outside confined chamber, and by changing air vent size, realizes the adjustment of wind speed field and the realization of wind velocity gradient.
Four, complex control system is based on the existing testing table control system in laboratory, more each related data monitored by the relevant intelligent sensor of combination, carries out Comprehensive Control.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Drawing illustrates:
(1) heating water pipe, (2) exhaust fan, (3) humidification water pipe, (4) Leakage Gas point, (5) gas transmission pipeline, (6) humidifying spraying nozzle, (7) airing hole, (8) floor heating capillary network.
Note: humidifying spraying nozzle is arranged crosswise, has only respectively drawn a row at confined chamber left and right sides in figure, and can arrange row arbitrarily by actual conditions at differing heights during actual experiment, often row should be no more than 5.
Embodiment
See Fig. 1, the gas diffusion test confined chamber of known adjustable meteorologic parameter of the present utility model is by heating water pipe (1), exhaust fan (2), humidification water pipe (3), Leakage Gas point (4), gas transmission pipeline (5), humidifying spraying nozzle (6), airing hole (7), the compositions such as floor heating capillary network (8).
The specific implementation process citing of the utility model device:
Flue gas lecture experiment: experimentally require that humiture, air velocity transducer are placed in relevant position in confined chamber, with the accuracy of the humiture and wind speed that ensure actual conditions and model measurement; Come control in confined chamber and regulate thermograde by floor heating capillary network (8), the adjustment of wind speed field and wind velocity gradient is realized by airing hole (7), exhaust fan (2), humidification room air is carried out again by humidifying spraying nozzle (6), make to reach in confined chamber and test moisture field that is required stable or that have gradient, flue gas enters confined chamber from gas leakage point (4).So, by the key monitoring point of (the adjustment change of epidemic disaster, wind speed and indoor particulate matter, the adjustment etc. of leak export model) under finding each space environment series of experiments condition, the number of times of gas leakage diffusion test can be reduced, also for the reasonable Arrangement of the respective sensor of gas leakage diffusion provides reference, simultaneously, according to flue gas diffusion can carry out safe distance preresearch estimates, security protection mode and the safe distance of test point personnel can also be determined.
This ensures that there and obtain data comparatively reliably under the condition of limited input, obtain final flue gas lecture experiment according to measured data and can represent actual measurement experiment to a great extent.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
