Outside setting blower, with combustion-supporting mechanism connection, the heat exchange mechanisms are set as being made of heat exchanger one and heat exchanger two, the row
Valve is respectively set in port and transition exhaust outlet, and is connected respectively by respective pipeline with corresponding heat exchanger one and heat exchanger two
It connects, pipeline of the pipeline of the transition exhaust outlet after heat exchanger again with blower is connect, and the CO concentration detecting mechanism is by setting
The CO concentration detector one and CO concentration detector two for being placed in exhaust outlet and transition exhaust ports form, the control mechanism difference
It is electrically connected, arranges with blower, the valve of exhaust outlet, the valve of transition exhaust outlet, CO concentration detector one and CO concentration detector two
Port is in communication with the outside after passing through heat exchanger one.
The combustion-supporting mechanism include with the fume centralized portion that is made into integration of installation shell, in fume centralized portion inside
Empty, bottom inlet is set as circular platform type, and combustion-supporting plate is arranged in top outlet flue, setting air inlet and peace in the middle part of the fume centralized portion
The external connection of shell is filled, the intake stack of the blower is connected to the hollow space in fume centralized portion.
The combustion-supporting mechanism is set as at least one set of.
The utility model structure is simple, improves CO concentration so that it burns more by being set to the combustion-supporting mechanism inside device
Add sufficiently, and promote the burning of other high-flash combustibles, according to flue gas after the control burning of exhaust outlet CO Concentration Testing situation
It moves towards, is discharged after the qualified direct retention heat by heat exchanger, passes through after the underproof retention heat by transition exhaust outlet
Blower feedback is back in combustion-supporting machine structure and burns away, realize heat maximally utilize and flue gas in combustible it is thorough
Burning, energy conservation and environmental protection are suitble to large-scale promotion application.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
