Description
Technical field
The present invention relates to Pneumatic feeding device field more particularly to a kind of Pneumatic feeding devices.
Background technique
Coal gasifier refers to the capital equipment of coal gasification；At present in gasification furnace when coal, it is usually used manually
Coal；The bell for opening top of gasification furnace is generally required in coal charcoal, this process tends to showing for gas leak occur
As being easy to happen explosion accident；And it can be mixed into portion of air, influence the use of gasification furnace.
Summary of the invention
The object of the present invention is to provide a kind of Pneumatic feeding devices for capableing of automatic charging.
Technical scheme is as follows:
A kind of Pneumatic feeding device, which is characterized in that including burner, which connect one end with inlet duct
It is connect by discharge nozzle with gasification furnace；The burner is externally provided with the wind chamber being connected to burner, wind chamber peripheral hardware having heaters；Institute
Stating inlet duct includes air blower, and the Venturi tube connecting with air blower, the Venturi tube other end is connect with burner；The Venturi tube
On be also connected with coal bunker, star-shaped discharge valve is additionally provided between coal bunker and Venturi tube；The wind chamber passes through gas valve and gasification furnace
Connection.
The discharge nozzle is connect with the test side of oxygen determination controller, and the control terminal of the side oxygen controller is connect with air blower.
By setting oxygen determination controller, it can effectively prevent thering is extra oxygen to enter burner hearth in mixed gas, once detect pipeline
In contain oxygen, the blower change of front end can be automatically cut off.
At least three groups of nozzle sets are evenly equipped in the burner cavity.By setting nozzle sets to spray the coal gas in wind chamber
Enter and mixes combustion in burner.
The nozzle sets include being set up and down two nozzles.By the way that two nozzles one on the other are arranged, so not
Only enable coal gas to quickly enter in burner and there are certain convection effects, increases flow velocity and accelerate mixed combustion.
The nozzle sets include first jet group, second nozzle group and third nozzle sets, the first, second, third nozzle sets
It include being set up and down two nozzles；The nozzle height of the second nozzle group is greater than the nozzle height of first jet group,
The height of first jet group nozzle is equal to the height of third nozzle sets nozzle.Since two centrally located nozzle heights are higher than two
The height of side nozzle not only has preferable convection effects in this way, but also can greatly improve the flow velocity of gas, so that mixed combustion is more
Rapidly.
The nozzle is in back taper.Using inverted cone-shaped structure, when coal gas sprays, strength is more concentrated, and convection effects are more preferable.
The beneficial effects of the present invention are: by the sky of air blower when the coal in coal bunker enters Venturi tube by star-shaped discharge valve
Gas brings the inner cavity of burner into, shifts to an earlier date the coal gas of cycle gasification furnace output in burner cavity and is heated to by housing heater
High temperature, air, which enters in burner, at this time to generate stronger pressure with the mixed combustion of coal gas, gas volume instantaneous expansion, which can
Moment increases the kinetic energy of coal, enters gasification furnace furnace roof by gas piping.
Detailed description of the invention
Through the following detailed description taken in conjunction with the accompanying drawings, present invention objects, features and advantages above-mentioned and other will become
Obviously.
Wherein: Fig. 1 is schematic structural view of the invention；
Fig. 2 is second nozzle group structural schematic diagram of the present invention；
In attached drawing, 1 is burner, and 2 be wind chamber, and 3 be heater, and 4 be air blower, and 5 be Venturi tube, and 6 be coal bunker, and 7 be star
Type discharge valve, 8 be gasification furnace, and 9 be oxygen determination controller, and 10 be nozzle, and 11 be first jet group, and 12 be second nozzle group, and 13 are
Third nozzle sets, 14 be gas valve.
Specific embodiment
It is shown in Figure 1, a kind of Pneumatic feeding device, which is characterized in that including burner 1, the burner one end with into
Device of air connects one end and is connect by discharge nozzle with gasification furnace 8；The burner is externally provided with the wind chamber 2 being connected to burner, wind
Chamber peripheral hardware having heaters 3；The inlet duct includes air blower 4, the Venturi tube 5 connecting with air blower, the Venturi tube other end with
Burner connection；It is also connected with coal bunker 6 on the Venturi tube, star-shaped discharge valve 7 is additionally provided between coal bunker and Venturi tube；The wind
Chamber is connect by gas valve 14 with gasification furnace.By air blower when coal in coal bunker enters Venturi tube by star-shaped discharge valve
Air brings the inner cavity of burner into, shifts to an earlier date the coal gas of cycle gasification furnace output in burner cavity and is heated by housing heater
To high temperature, air, which enters in burner, at this time to generate stronger pressure, the pressure with the mixed combustion of coal gas, gas volume instantaneous expansion
The kinetic energy of coal can be made to increase moment, enter gasification furnace furnace roof by gas piping；By gas valve will turn in gasification furnace
The coal gas for changing completion leads in air-inlet chamber, save the cost.
The discharge nozzle is connect with the test side of oxygen determination controller 9, and the control terminal of the side oxygen controller is connect with air blower.
By setting oxygen determination controller, it can effectively prevent thering is extra oxygen to enter burner hearth in mixed gas, once detect pipeline
In contain oxygen, the blower change of front end can be automatically cut off.
At least three groups of nozzle sets are evenly equipped in the burner cavity.By setting nozzle sets to spray the coal gas in wind chamber
Enter and mixes combustion in burner.
The nozzle sets include being set up and down two nozzles 10.By the way that two nozzles one on the other are arranged, in this way
Not only enable coal gas to quickly enter in burner but also there are certain convection effects, increases flow velocity and accelerate mixed combustion.
The nozzle sets include first jet group 11, second nozzle group 12 and third nozzle sets 13, and first, second, third
Nozzle sets include two nozzles that (being oppositely arranged in the up-down direction) is arranged one on the other；The nozzle of the second nozzle group is high
Degree is greater than the nozzle height of first jet group, and the height of first jet group nozzle is equal to the height of third nozzle sets nozzle.Due to
Two centrally located nozzle heights are higher than the height of two side nozzles, not only have preferable convection effects in this way, but also can
The flow velocity of gas is greatly improved, so that mixed combustion is rapider.
The nozzle is in back taper.Using inverted cone-shaped structure, when coal gas sprays, strength is more concentrated, and convection effects are more preferable.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is all according to
According to any simple modification to the above embodiments in technical spirit of the invention, equivalent variations, guarantor of the invention is each fallen within
