Description
Technical field
The utility model belongs to field of boilers more particularly to a kind of low nitrogen condensing boiler of combustion gas.
Background technique
Currently, the low nitrogen condensing boiler of combustion gas generallys use surface water-cooled, including mixing tank, wind collection, the one of mixing tank
Side is fixedly connected with capping, and one end of wind collection is set in the cavity of mixing tank；Combustion air is provided on the cabinet of mixing tank
Air inlet and natural gas air inlet are provided with the gas central pipe of bending on natural gas air inlet；Gas central pipe includes water
Flat pipe portion and vertical pipe portion；Horizontal tube section is provided with spinning disk component on the tube wall of vertical pipe portion and several are circumferentially equal
The even overflow hole being laid on tube wall, is additionally provided with baffle assembly in horizontal tube section, and the external of the wind collection other end extends
It is arranged with spiral cooling tube；Spiral cooling tube is provided with cold water inlet and hot water outlet.
But there are the following problems in actual use:
1, since wind collection generallys use straight sleeve, and combustion gas is flowed in wind collection along cyclone mode, so wind collection
Barrel the eddy flow of combustion gas can be hindered to disperse, can not effectively eddy flow be distributed on spiral cooling tube, and mainly use center boundling
Mode flowed through from the central axis of spiral cooling tube, cause water cooling efficiency reduction, influence cool down efficiency.
2, since spiral cooling tube also uses straight sleeve structure, so it can only be cold to the hot-fluid progress for flowing through inner surface
But, center boundling hot-fluid cannot be cooled down, causes hot-fluid the phenomenon that heat center concentration occur, influences temperature controlled essence
Degree.
Utility model content
The purpose of this utility model is to provide a kind of low nitrogen condensing boilers of combustion gas that accuracy of temperature control is high, and technical solution is such as
Under:
The low nitrogen condensing boiler of combustion gas, the spiral cooling tube including wind collection and its downstream connection, coaxial grafting in wind collection
There is gas central pipe, spiral cooling tube includes diversion pipe of the straight tube with the M type being connected on straight tube for being socketed in duct set periphery,
Diversion pipe, which has from downstream, protrudes into the closed central protrusion portion in straight tube and upstream end and the side for being looped around straight tube downstream peripheral
Turn-up portion, diversion pipe and straight tube surround the drainage channel of M type.
Straight tube and/diversion pipe include spiral heat-dissipating pipe, and heat-dissipating pipe and drainage channel are equipped at intervals with corrugated plating.
Wind collection is the conical sleeve being gradually increased along airflow direction internal diameter, is set on gas central pipe and kisses with wind collection
