Description
Technical field
The present invention relates to exhaust pipe technical fields, more particularly, to a kind of fire prevention flow-guiding type flue and difunctional exhaust system
System.
Background technique
There are three types of types for the smokejack of multistoried housing construction, i.e., in major-minor flue, reverse-filling check (non-return) valve flue and pressure swing type
High-rise flue, but currently, kitchen, defend in the technology of exhaust system, resident can only change by oneself fume exhauster for kitchen or toilet
Gas fans mechanical forced-ventilated, and the unclean air in kitchen or toilet is discharged into outdoor, carries out room ventilation ventilation.
Since the exhaust system of existing technology is after indoor exhaust air is discharged into exhaust system by range hood or ventilation fan, row
Exhaust gas in gas system cannot be dredged in time is emitted into ambient atmosphere layer, causes range hood or ventilation fan to increase energy consumption, simultaneously
The capacity into exhaust system is reduced, so as to cause house kitchen, defends a kind of use space as morbid state；And currently on the market
There are no a kind of exhaust passage systems can effectively solve these problems, and existing blank in the industry is caused to fail to be filled out always
It mends.
Summary of the invention
The purpose of the present invention is to provide a kind of fire prevention flow-guiding types with the natural degassing function in mechanical forced-ventilated and 24 hours
Flue and difunctional exhaust system are difficult the technical issues of effectively discharging to solve exhaust gas existing in the prior art.
