Description

Pressure variable exhausting channel
Technical field
The invention belongs to a kind of pressure variable exhausting channel.
Background technology
The relevant design specifications requirement of dwelling house, the kitchen planted agent is provided with common exhaust duct.This pipeline should be able to satisfy the necessary ventilation of kitchen mist extractor, and should have the function of anti-taint of odour, string sound.According to this instructions for use, adopt by same upright position, the exhaust opening of each layer oil-containing air exhauster for kitchen combines in the air channel, the pipe-line system of atmospheric dilution to the top.Because the setting of this pipe-line system; Each layer kitchen that is in same upright position is interconnected; And when certain oil-containing air exhauster for kitchen starts in pipe-line system forced exhaust in system's (with each floor of Stall); For being barotropic state everywhere in the common exhaust duct system that only adopts a simple air channel structure, then all not the smoke exhaust intake of other shut down condition of the disconnected device of handicapping the string wind of inequality is all arranged, " gas blowby ", " scurrying flavor " phenomenon of each interlayer promptly taken place.A very important instructions for use of house kitchen common exhaust duct system exactly will be under the prerequisite that satisfies the necessary vented exhaust amount in kitchen, the function of use of should have not " gas blowby ", " not scurrying flavor ".
China utility model patent CN2180711 has announced a kind of pressure variable exhausting channel; It mainly is because the trunk line of exhaust is formed with component for variable-pressure, guide pipe on the wall that sets within it; Trunk line is provided with air inlet port, and guide pipe is connected with air inlet port, and its component for variable-pressure is the trihedral parts that are made up of head slab, positive flat board and bottom panel; Its both sides press closer on the inwall of the trunk line of a corresponding side, because the both sides of component for variable-pressure press closer on the trunk line inwall.Its operating principle mainly is according to dynamic and static pressure transfer principle, that is: Pq=Pj+Pd in the aerodynamics; The arbitrary flow area total head of Pq-value; Pj-Pq section static pressure; Pd-Pq section dynamic pressure value.The concrete practice is; It is component for variable-pressure that local member is set in pipe-line system; Flow to the size with flow area to change primary air, thereby eliminate the retardation of air curtain and press and quiet moving conversion, make under the shared ventilation system operation condition that each layer smoke exhaust of all various combinations open, stop forming in the ad-hoc location completion; Be and respectively inhale the local static pressure Pj of population (being air intake)<0, ingenious and simple and direct " gas blowby " that prevents each layer kitchen effectively under the stopped status.At present, this pressure swing type common exhaust duct system popularization and application day by day.
But the component for variable-pressure of different volumes blindly is set in common exhaust duct, this transformer action is descended, also can limit the decline that hinders common exhaust duct air draft effect, cause result of use not good.
Summary of the invention
The present invention seeks to design a kind of pressure variable exhausting channel; The proportionate relationship of each parts in the exhaust duct is provided; Make the local static pressure negative value of each air intake of pressure variable exhausting channel minimum, prevented that effectively " gas blowby " phenomenon in each layer kitchen from existing, also have and save material and the advantage that reduces cost.For this reason, the present invention adopts and is made up of exhaust duct, guide pipe and component for variable-pressure;
