Amalgamated dwelling flue purifying and discharging system

Abstract

The invention provides an amalgamated dwelling flue purifying and discharging system which comprises a vertically arranged centralized flue. The centralized flue is communicated with each smoke exhaust ventilator arranged at each storey. The amalgamated dwelling flue purifying and discharging system is characterized in that the amalgamated dwelling flue purification discharging system further comprises a cleaning device, an oil stain recovery device, a pumping and drainage type static oil fume purifying and discharging device and a control device; the cleaning device is used for cleaning the centralized flue; the oil stain recovery device is arranged below the centralized flue and used for recovering oil stains and / or liquid waste generated after the centralized flue is cleaned; the pumping and drainage type static oil fume purifying and discharging device is used for forming negative pressure in the centralized flue so as to purify and discharge oil fume in the centralized flue; the control device is used for controlling the pumping and drainage type static oil fume purifying and discharging device according to preset time or oil fume concentration in the centralized flue to form negative pressure in the centralized flue. The amalgamated dwelling flue purifying and discharging system can prevent oil fume in the smoke exhaust ventilators from flowing backwards and avoid unsmooth fume discharging, and discharged oil fume is clean; particularly, the amalgamated dwelling flue purifying and discharging system can lower potential fire hazards and keep the centralized flue clean.

Description

technical field [0001] The invention relates to the technical field of cooking oil fume discharge, in particular to a flue cleaning and discharge system for a collective house suitable for building residential groups. Background technique [0002] The increasingly widely used range hood has created conditions for the collection of kitchen fume, but the emission of fume, especially the concentrated discharge of fume gas in modern residential buildings has not been properly resolved so far. Concentrated flue is adopted in the existing building residential group, and a hood is arranged at the end of the flue. The flue in the residential complex of the building is connected to the range hoods of each family on each floor. When one family cooks, the smoke easily flows into other families along the flue through the range hood, causing a family to suffer from smoke damage. Simultaneously, when many people cook at the same time, there is a large amount of oily smoke in the concentr...

Problems solved by technology

At the same time, when many people are cooking at the same time, there will be a lot of oil fumes in the centralized flue, which will make the oil fumes of each cooking house difficult to discharge, and the smoke will spread in their own homes.

In addition, after the existing centralized flue is used for a long time, an oil stain layer will be formed on the flue wall. After a large amount of oil fume is concentrated, the temperature in the concentrated flue will rise, which will cause the oil stain to ignite, posing a fire hazard.
