Abstract
The utility model relates to a kind of low nitrogen hot-water boilers of combustion gas, including wind collection and its interior coaxial mounted gas central pipe, wind collection is the conical sleeve being gradually increased along airflow direction internal diameter, and the spinning disk component and baffle assembly of the clearance fit coincideing with wind collection are set on gas central pipe.The inhibition to eddy flow combustion gas is reduced using the diffusion structure of taper wind collection, in this way in combustion gas after wind collection reaches spiral cooling tube, combustion gas can be tightly attached on spiral cooling tube always, improve water cooling efficiency and cooling efficiency.
Description
Technical field
The utility model belongs to field of boilers more particularly to a kind of low nitrogen hot-water boiler of combustion gas.
Background technique
Currently, the low nitrogen hot-water 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 since wind collection generallys use straight sleeve, and combustion gas is flowed in wind collection along cyclone mode, so collection wind
The barrel of cylinder can hinder the eddy flow of combustion gas disperse, can not effectively eddy flow be distributed on spiral cooling tube, and mainly using center collection
The mode of beam is flowed through from the central axis of spiral cooling tube, is caused the reduction of water cooling efficiency, is influenced the efficiency that cools down.
Utility model content
The purpose of this utility model is to provide a kind of low nitrogen hot-water boilers of combustion gas that water cooling is high-efficient, and technical solution is such as
Under:
The low nitrogen hot-water boiler of combustion gas, including wind collection and its interior coaxial mounted gas central pipe, wind collection are along air-flow
The conical sleeve that direction internal diameter is gradually increased is set with the spinning disk group for the clearance fit coincideing with wind collection on gas central pipe
Part and baffle assembly.
Spinning disk component and baffle assembly are axially alternately distributed in gas central pipe.
There are two spinning disk components, and the spinning disk component downstream positioned at upstream is offered on the tube wall of gas central pipe
The spinning disk component at position and downstream is close to the overflow hole of upstream position, and overflow hole is in gas central Guan Shangcheng dot matrix point
Cloth.
Baffle assembly includes the guide ring for being coaxially set in gas central pipe periphery, and the outer peripheral surface of guide ring is and collection wind
The inner peripheral surface of the conical surface of the identical clearance fit of cylinder, guide ring is trapezoidal faces, and support is connected between guide ring and gas central pipe
Along the circumferential direction uniformly distributed support spoke.
The beneficial effects of the utility model are as follows:
The inhibition to eddy flow combustion gas is reduced using the diffusion structure of taper wind collection, is arrived in this way in combustion gas through wind collection
Up to after spiral cooling tube, combustion gas can be tightly attached on spiral cooling tube always, improve water cooling efficiency and cooling efficiency.
Detailed description of the invention
It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment
Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the embodiments of the present invention, for this
For the those of ordinary skill of field, without any creative labor, it can also be obtained according to these attached drawings other
Attached drawing；
Fig. 1 is the collection wind structural schematic diagram of boiler.
Specific embodiment
In order to keep the technical purpose, technical scheme and beneficial effects of the utility model clearer, with reference to the accompanying drawing and
Specific embodiment is further illustrated the technical solution of the utility model.
Referring to Fig. 1, show in the low nitrogen hot-water boiler of combustion gas in the utility model between igniter and spiral cooling tube
Collect wind structural schematic diagram, specific structure is as follows:
The low nitrogen hot-water boiler of combustion gas includes wind collection 1 and its interior coaxial mounted gas central pipe 2, and wind collection 1 is along gas
The conical sleeve that direction internal diameter is gradually increased is flowed, the eddy flow for the clearance fit coincideing with wind collection 1 is set on gas central pipe 2
Piece component 3 and baffle assembly.Spinning disk component 3 and baffle assembly are axially alternately distributed in gas central pipe 2.Spinning disk group
There are two parts 3, is offered at the 3 downstream position of spinning disk component of upstream on the tube wall of gas central pipe 2 and downstream
Spinning disk component 3 close to upstream position overflow hole 4, overflow hole 4 on gas central pipe 2 in dot matrix be distributed.
Baffle assembly is made of one group of outer ring deflector 51 and one group of inner ring deflector 52, in two groups of spinning disk components 3
Between, baffle assembly has two groups, and in two groups of baffle assemblies, inner ring deflector 52 and outer ring deflector 51 are alternately distributed.?
3 downstream of spinning disk component in downstream is provided with one group of baffle assembly.The difference of inner ring deflector 52 and outer ring deflector 51 is only
It is outer diameter.Its structure includes the guide ring for being coaxially set in the periphery of gas central pipe 2, and the outer peripheral surface of guide ring is and wind collection
The inner peripheral surface of the conical surface of 1 identical clearance fit, guide ring is trapezoidal faces, and support is connected between guide ring and gas central pipe 2
Along the circumferential direction uniformly distributed support spoke.
It should be noted last that: the technical solution of the utility model that the above embodiments are only illustrative and not limiting is appointed
What to the utility model carry out equivalent replacement and do not depart from the spirit and scope of the utility model modification or part replace,
It should cover within the scope of the utility model claims protection.
