The invention relates to an exhaust passage structure of a storied house, in particular a dwelling house, and discloses a multi-power source adjustable voltage-transforming fire-proof exhaust passage system. The system comprises one or more voltage-transforming exhaust devices arranged on one exhaust passage, wherein each of the voltage-transforming exhaust devices comprises a fire-proof check valve, a Venturi active plate and a connecting component. In the voltage-transforming exhaust devices between different floors in the same exhaust system, the vertical distances between the Venturi active plates and an assembling plate are different and the included angles beta between the Venturi active plates and the horizontal plane are different. In the system, the exhaust amount between floors is balanced by adjusting an angle alpha of a guide plate of the fire-proof check valve at an air inlet; the beta is approximately equal to the alpha by adjusting a horizontal angle beta of the Venturi active plate arranged opposite to the fire-proof check valve; the optimal Venturi effect is achieved through the same curve rate; the loss of the air flow energy passing through the voltage-transforming exhaust device is reduced to the minimum; and the problem that centralized exhaust on the lower floors of a dwelling building is not smooth and ideal is solved.
Description
Technical field
The present invention relates to the especially air discharging structure of dwelling house of building, relate in particular to the adjustable transformation fire prevention of multi power source exhaust duct system.
Background technology
At present, in residential kitchen and toilet is concentrated the exhaust duct system, the multi power source exhaust system that operation condition is formed by many even tens induced-draft fans or exhaust fan.Which kind of but no matter all can occur the closer to top layer during exhaust duct system practical application at present; Between adjacent two layers the upper strata induced-draft fan than the exhaust smoke level of lower floor is big must be many more. more serious situation is: if all higher than strong wind piezometric head near the power of certain or certain several induced-draft fans of bottom; Then can make bottom or very little, even can not discharge fume near the exhaust air rate of the lower-powered induced-draft fan of bottom.Exhaust duct is exhaust from bottom to top, and the fume emission flow process of bottom floor is the longest, exhaust duct also maximum along journey frictional resistance; Capacity is also minimum, and the floor fume emission flow process of top layer is the shortest, exhaust duct also minimum along journey frictional resistance; Capacity is also maximum, and the capacity size of top layer and bottom differs even up to several times, the result is that a large amount of fume emissions of upper floor resident family have taken whole concentrated exhaust duct; The flue gas of bottom floor resident family is concentrated exhaust duct because of the little and very difficult entering of capacity, causes that exhaust is smooth, the ineffective phenomenon of exhaust, to these situation; Common technological means is to adopt the structure of transformation exhaust to solve at present; But since the transformation structure of using in the market normally during actual installation the position of variable-pressure plate can't correctly lay, in addition its structure this when producing Venturi effect, the resistance of generation is also very big; Energy loss is many; Especially high residential building adopts existing transformation structure can't solve the middle and lower part flue gas effectively to discharge, have a strong impact on IAQ, and then influence the healthy of resident at all.Add that each user chooses and install lampblack absorber or ventilation fan arbitrarily voluntarily at present, cause pressure and air quantity confusion between each layer of same system exhaust duct, make the more effectively exhaust of flue gas of middle and lower part floor.And addressing these problems of not having also in the market that a kind of exhaust duct system can be effective and easy.
Summary of the invention
The present invention is directed to venturi unreasonable structure in the prior art, non-science, the asymmetric flue gas that causes in the transformation process; Resistance is big; The lampblack absorber energy loss is many, and the shortcoming that middle and lower part floor flue gas can't effectively be discharged provides a kind of floor exhaust duct internal pressure balance up and down that makes; Stability of flow is easy to make, the adjustable variable-pressure exhaust passage of the multi power source system of I&M; And solved when choosing and installing lampblack absorber or exhaust fan voluntarily arbitrarily because of existing user and cause floor exhaust duct air inlet port place's pressure and air quantity imbalance up and down, and make smooth, the not ineffective problem of middle and lower part floor exhaust.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals:
The adjustable transformation fire prevention of multi power source exhaust duct system; Comprise and be arranged on one or more transformation exhaust plant on the exhaust duct; The transformation exhaust plant comprises and can realize changing air guide port big or small fire-preventing check valve, venturi portable plate and connector by adjusting angle; The right opposite of described fire-preventing check valve be provided with can adjusting angle the venturi portable plate; In the transformation exhaust plant between the different floors of same exhaust system, the horizontal range between venturi portable plate and the buck plate is inequality.
