It elaborates below by drawings and examples to the utility model.
Detailed description of the invention
Fig. 1 is provided by the utility model using hydrogen or methane as the signal of the composed structure of the Coalblowing system of carrier
Figure.
Specific embodiment
As shown in Figure 1, forming original by the Coalblowing system of carrier of hydrogen or methane to be provided by the utility model
Managing schematic diagram includes in the present embodiment nitrogen air inlet valve group 1, hydrogen using hydrogen or methane as the Coalblowing system of carrier
Gas air inlet valve group 2, methane air inlet valve group 3, injection tank 4, blowing feeding device 5, exhaust regulating valve 6, deduster 7, injection tank into
Expect valve 8, injection tank outlet valve 9 and the injection pipeline 10 for being communicated to downstream process system 11.
Pipeline one end where nitrogen air inlet valve group 1 connects source nitrogen, and it is pair that the other end is connected to the lower part of injection tank 4
Injection tank 4 carries out pressurising, fluidisation nitrogen seals air intake assembly, carries out pressurising to the coal dust in injection tank 4 by nitrogen, fluidisation nitrogen envelope is protected
Shield, so as not to air be mixed into occur spontaneous combustion of pulverized coal, explosion risk, and by nitrogen carry out pressurising, fluidisation so as not to blowing use hydrogen/
Methane enters injection tank 4, and release is discharged into atmosphere and causes danger when subsequent 4 blanking of injection tank.Nitrogen described in the present embodiment
Air inlet valve group 1 includes a hand-operated valve, a pneumatic intake valve, a regulating valve, a non-return valve, is also filled with flow and pressure detecting
It sets.
Hydrogen gas valve group 2 and methane air inlet valve group 3 are all the air intake assemblies of blowing gas, according to the needs of different blowings
It opens hydrogen gas valve group 2 or methane air inlet valve group 3 is blown, hydrogen gas valve group 2 and methane described in the present embodiment
Air inlet valve group 3 respectively contains a hand-operated valve, a pneumatic intake valve, a regulating valve, a non-return valve, also has flow and pressure detecting
Device.Preferably, this part pipe valve uses stainless steel material, causes danger in order to avoid corrosion of carbon steel gets rusty.
Injection tank 4 is to realize the storage equipment of breeze blowing, is equipped with inlet valve 8, deduster 7 and blowing feed thereon and sets
Standby 5, nitrogen air inlet valve group 1 is connect with the fluidisation pressure-applying unit in injection tank 4, hydrogen gas valve group 2 and methane air inlet valve group 3 and
It is blown the air inlet connection of feeding device 5.
Blowing feeding device 5 is to realize the core equipment being accurately continuously blown, and generally one turns with gas lock function
Feeding device is moved, selects vertical rotating batcher in the present embodiment, is the patent of present applicant, the patent No.: ZL
201320480948.2.Blowing 5 top of feeding device is connected with the outlet of injection tank 4, and coal dust passes through on vertical rotating batcher
The feed inlet of top plate enters vertical rotating batcher, by the rotation of vertical rotating batcher by coal dust from vertical rotating batcher bottom
The outlet in portion is fallen, which has individual air inlet, air inlet and hydrogen gas component or methane air inlet group
Pipeline where part is connected, and is the accurate feeding function of completing breeze blowing using blowing feeding device 5, but also injection tank
Interior nitrogen and blowing hydrogen or methane security isolation, are blown with realizing using hydrogen or methane.
Exhaust regulating valve 6 be control injection tank pressure regulating valve, in order to avoid in injection tank nitrogen and blowing hydrogen or
Methane pressure difference is excessively high to be caused to be blown 5 failure of feeding device or nitrogen and hydrogen or methane cannot be completely isolated, by nitrogen into
6 regulation blowing pressure inside the tank of air valve group 1 and exhaust regulating valve makes nitrogen pressure and blowing pipeline hydrogen or methane pressure in injection tank
Dynamic balance is equal, not only protects blowing feeding device 5 in this way, but also can enable nitrogen and hydrogen or methane security isolation.
Filter plant when deduster 7 is the exhaust release of injection tank 4, nitrogen is discharged into atmosphere after being filtered by deduster 7, with
Exempting from coal dust exhaust influences environment.
Injection tank inlet valve 8 is the feed inlet of injection tank 4, injection tank 4 can be added in coal dust by inlet valve 8.It is preferred that
Ground, the inlet valve 8 use dome valve.
Outlet valve 9 is the separation valve door of injection tank 4 and injection pipeline 10, for system just started starting when and after
Injection tank and blowing pipeline is isolated.Preferably, injection tank outlet valve uses dome valve.
Injection pipeline 10 is the conveyance conduit of pulverized coal injection, due to being blown using hydrogen or methane, so injection tube
Road 10 uses stainless steel material
Downstream process system 11 is the terminal of pulverized coal injection, is blown using hydrogen or methane, hydrogen or methane enter downstream
Process system 11 normal operating parameters in downstream are not influenced after process system 11.
The course of work of whole system is described in detail below:
1) operator issues start command, and injection tank outlet valve 9 is closed, hydrogen gas valve group 2 or methane air inlet valve group
3 open, and hydrogen or methane enter injection pipeline and starts to blow injection pipeline 10 clearly；
2) 6 standard-sized sheet injection tank of exhaust regulating valve, 4 pressure decline, opened when pressure drops to setting value in injection tank 4 into
Mouth valve 8, coal dust start to fall into injection tank；
3) after injection tank weighing system shows that injection tank is already filled with, inlet valve 8 is closed, and exhaust regulating valve 6 is closed,
Nitrogen air inlet valve group 1 is opened；
4) pressure is begun to ramp up in injection tank 4, when being blown pressure inside the tank and after equal 10 pressure of injection pipeline, hydrogen into
Air valve group 2 and/or methane air inlet valve group 3 are opened, and injection tank outlet valve 9 is opened, and blowing feeding device 5 starts to start, and coal dust is logical
Blowing feeding device 5 is crossed to enter injection pipeline 10 and then be blown into downstream process system 11；
5) exhaust regulating valve 6 is constantly adjusted according to blowing pressure inside the tank during blowing, makes to be blown pressure inside the tank
It is equal with 10 pressure balance of injection pipeline；
When breeze blowing terminates in injection tank, when needing tank switching, injection tank outlet valve 9 is closed, and blowing feeding device 5 stops
Only, hydrogen gas valve group 2 and/or methane air inlet valve group 3 are closed, and nitrogen air inlet valve group 1 is closed, and exhaust regulating valve 6 opens blowing
Pressure inside the tank decline prepares next blanking circulation.
