Description
Technical field
The utility model relates to catalytic combustion device technical field, specially a kind of gas mixer.
Background technique
When existing catalytic combustion device uses, need to mix to air with exhaust gas, to reduce exhaust gas
Concentration can be carried out adequately convenient for subsequent catalysis burning；But because exhaust gas and air enter the flow velocity of gas pipeline
Quickly, often there is the problem of exhaust gas and air mixing unevenness, will lead to local gas in later period catalytic process and react insufficient,
Reduce whole purification efficiency.
Summary of the invention
In order to solve the problems, such as that air and exhaust gas undercompounding, the utility model provide a kind of gas mixer,
Air and waste gas can be made to be sufficiently mixed, subsequent catalyst process is enable sufficiently to carry out.
The structure of the utility model is such that it includes exhaust gas entrance, air intake, spiral board, tube body, the exhaust gas
Entrance is located at one end of the tube body, and the spiral board is set to the other end of the tube body, and the air intake connects air
Pipeline, it is characterised in that: the diameter of the air pipeline is less than the radius of the tube body, and the air pipeline is along the tube body
The tangential direction of upper end pipe outer wall be inserted into the tube body；The spiral board is umbrella, the blade of the spiral board and the pipe
There is angle in the radial end face of body.
It is further characterized by:
The angular range is 15 degree ~ 30 degree；
It further includes flowing to transformational structure, described to flow to the steel plate that transformational structure includes wave-like, and the steel plate is parallel
Be installed in tube wall, constitute wavy mixed-gas channel between two adjacent steel plates, the flow direction conversion
Structure is connect by connecting component with adjacent component；
The adjacent steel plate for flowing to transformational structure is orthogonal；
Sealing element is provided with outside the connecting component.
A kind of gas mixer provided by the utility model, air is along exhaust piping radially into tube body, edge pipe
What the tube wall direction of body rotated carries out mixed once with relatively slow speed and exhaust gas, and mixed effect is more preferable；After mixed once
Gas cross spiral board, generate eddy flow using the kinetic energy of itself of two kinds of gas, carry out secondary mixing；Because of the gas stream entered
Fast very fast, the angle of spiral board and radial end face can play the role of drainage dispersion, make mixed gas is more efficient to lead to
Spiral board is crossed, secondary mixed efficiency is improved；After the utility model, two kinds of gases into device are mixed twice
It closes, keeps gas mixing more abundant.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of mixing arrangement；
Fig. 2 is mixing arrangement A-A the schematic diagram of the section structure；
Fig. 3 is the B-B the schematic diagram of the section structure for flowing to transformational structure.
Specific embodiment
As shown in Fig. 1 ~ Fig. 3, the utility model includes exhaust gas entrance 1-1, air intake 2-1, spiral board 3, tube body 1, is given up
Gas entrance 1-1 is located at one end of tube body 1, and spiral board 3 is set to the other end of tube body 1, air intake 2-1 connection air pipeline 2,
The diameter of air pipeline 2 be less than tube body 1 radius, air pipeline 2 along the upper end pipe outer wall of tube body 1 tangential direction insertion tube
Body 1；Spiral board 3 is umbrella, and there is angle in the radial end face of the blade 3-1 of spiral board 3 and tube body 1, when the gas stream passed through
When speed is larger, the angle of the radial end face of blade 3-1 and tube body 1, make mixed gas it is stronger flow to tube wall direction, touch
It is mixed again after hitting；The secondary mixed mixed effect of gas is more preferable when angular range is 15 degree ~ 30 degree.
Flow to transformational structure 4 including wave-like steel plate 4-1, multiple steel plate 4-1 it is parallel be installed in tube wall 4-4,
Wavy mixed-gas channel 4-2 is constituted between two adjacent steel plate 4-1, transformational structure 4 is flowed to and passes through connecting component
4-3 is connect with adjacent component；Adjacent when flowing to transformational structure 4 and connecting, the steel plate 4-1 of the two is orthogonal；Connecting component
It is provided with sealing element 5 outside 4-3, the connection of all parts is made to keep air-tightness；Secondary mixed mixed gas enters first
A to flow to transformational structure 4, the mixed gas passed through is divided into multiple little airflows by wavy mixed-gas channel 4-2 again,
Cutting mixes gas further, and wavy gas passage 4-2 slows down the flow velocity of gas, and the gas flowed through is abundant
Mixing；Subsequently into second flow direction converting 4, because of steel plate and first flow direction in second flow direction converting
The steel plate of conversion equipment is orthogonal, i.e., after mixed gas enters the mixed-gas channel 4-2 in second flow direction converting,
Airflow direction produces conversion, then is divided again into the mixed gas of second flow direction converting 4, and converts flow direction,
Further improve mixed effect.
After the technical solution of the utility model, mixed exhaust gas and air, into device after carry out
It mixes for the first time, has carried out second by spiral board and mixed；Flow direction converting is by cutting mixed gas and being turned
The change of current is to being further sufficiently mixed；And it, can be according to the flow velocity of the gas of entrance when using the present apparatus
Difference increases or reduces the number for flowing to transformational structure, the gas entered is made to reach suitable mixed effect, can be according to need
The transformational structure that flows to be increased and decreased makes the present apparatus have better adaptability.
