Abstract
A kind of MSW Incineration Plant garbage pool vacuum control system, including garbage pool, sampling below atmospheric pressure pipe and transmitter, DCS I/O switch boards, central control room, control valve and blower fan, uniform intervals are disposed with four sampling below atmospheric pressure pipes and transmitter respectively for the garbage pool both sides, both ends are respectively disposed with two sampling below atmospheric pressure pipes and transmitter, those sampling below atmospheric pressure pipes and transmitter pass through cable connection central control room by pressure signal cable connection DCS I/O switch boards, DCS I/O switch boards；The both ends of the garbage pool are controlled by pipeline sequential concatenation control valve, blower fan and activated carbon adsorber, control valve and blower fan by DCS I/O switch boards respectively.The utility model ensures under any operating mode, garbage pool effectively prevents that foul smell is excessive in garbage pool all in negative pressure state due to using above-mentioned structure design.
Description
Technical field
Technical field of waste treatment is the utility model is related to, especially a kind of MSW Incineration Plant garbage pool negative pressure
Control system.
Background technology
Garbage pool is the important component of waste-to-energy plant, and the house refuse into garbage pool can typically store 5-
7 days, and during storage, heap ferment, rubbish can distribute and discharge substantial amounts of foul smell naturally because of the effect of microorganism, and it is led
It is hydrogen sulfide to want composition（H2S）, mercaptan, ammonia（NH3）Deng.
In order to prevent that it is excessive that garbage pool stench from condensing in atmosphere, the inlet scoop of primary air fan is generally arranged at garbage pool
Top, garbage pool is in micro-vacuum state, not only efficiently control foul smell and escape, but it is simultaneously empty using foul gas as burning
Gas leads to incinerator, foul gas pyrolytic in incinerator, and smell is removed；But primary air fan mainly coordinates pot
The air capacity of fuel combustion needed for stove load variations changes and changed, and this has resulted in garbage pool negative pressure variation, while garbage pool
Bulky, general power plant fills 3-4 platform waste incineration lines, in a boiler operatiopn, it is difficult to ensure that garbage pool negative pressure, especially
It it is night, the load reduction of whole power network, many enterprise's incinerator loads are also reduced, and primary air flow reduces, and this is tieed up to garbage pool
It is just relatively difficult to hold negative pressure, and causes refuse-burning plant night stench excessive, the reason for causing resident to have strong complaints.In addition,
Garbage unloading door uses the form of slide-lifting door, is controlled by special messenger, after cram packer enters workshop, opens Dump gate and rubbish inclines
Pour into garbage pool, close Dump gate in time after completing discharging, make garbage pool closure, to ensure that it is negative that garbage pool can be formed
Pressure.
To prevent pollution of the stench of garbage pool to surrounding environment, foul smell in garbage pool is configured to be taken out on garbage pool top
Airduct and exhaust outlet suction out, and being sent into charcoal absorption formula odor removal by blower fan purifies heel row to outdoor, in fact, above-mentioned measure
Still fail to obtain optimal stench control effect.
The content of the invention
For technical problem of the prior art, the purpose of this utility model is to provide a kind of MSW Incineration Plant
Garbage pool vacuum control system, environment caused by can effectively preventing foul smell excessive influence.
To achieve the above object, technical scheme is used by the utility model：
A kind of MSW Incineration Plant garbage pool vacuum control system, including garbage pool, sampling below atmospheric pressure pipe and pick-up
Device, DCS I/O switch boards, central control room, control valve and blower fan, uniform intervals are disposed with four respectively for the garbage pool both sides
Individual sampling below atmospheric pressure pipe and transmitter, both ends are respectively disposed with two sampling below atmospheric pressure pipes and transmitter, those sampling below atmospheric pressure pipes and change
Device is sent to pass through cable connection central control room by pressure signal cable connection DCS I/O switch boards, DCS I/O switch boards；Institute
The both ends of garbage pool are stated respectively by pipeline sequential concatenation control valve, blower fan and activated carbon adsorber, control valve and blower fan are by DCS
I/O switch boards control.
Compared with prior art, the beneficial effects of the utility model are：
Due to using above-mentioned structure design, ensure under any operating mode, garbage pool effectively prevents all in negative pressure state
Foul smell is excessive in garbage pool.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Each label is respectively in figure：（1）Garbage pool,（2）（3）（4）（5）（6）（7）（8）（9）（10）（11）（12）（13）It is negative
Probe tube and transmitter are pressed,（14）DCS I/O switch boards,（15）Central control room,（16）（17）Control valve,（18）（19）Wind
Machine,（20）（21）Activated carbon adsorber.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Refer to Fig. 1, a kind of MSW Incineration Plant garbage pool vacuum control system of the utility model, including rubbish
Pond 1, sampling below atmospheric pressure pipe and transmitter, DCS I/O switch boards 14, central control room 15, control valve and blower fan, the garbage pool
1 side uniform intervals are disposed with four sampling below atmospheric pressure pipes and transmitter 2, and 3,4,5, opposite side uniform intervals are disposed with four negative pressure
Probe tube and transmitter 6,7,8,9, one end of the garbage pool 1 is respectively disposed with two sampling below atmospheric pressure pipes and the He of transmitter 10
11, the other end is respectively disposed with two sampling below atmospheric pressure pipes and transmitter 12 and 13, and those sampling below atmospheric pressure pipes and transmitter pass through pressure
Force signal cable connection DCS I/O control valves 14, DCS I/O switch boards 14 pass through cable connection central control room 15；The rubbish
The one end in rubbish pond 1 passes through pipeline order by pipeline sequential concatenation control valve 16, blower fan 18 and activated carbon adsorber 20, the other end
Control valve 17, blower fan 19 and activated carbon adsorber 21 are concatenated, control valve 16 and 17, blower fan 18 and 20 are by DCS I/O switch boards 14
Control.
During utility model works, the negative pressure in the sampling below atmospheric pressure pipe and transmitters sense garbage pool arranged in garbage pool 1
And electric signal is converted thereof into, those electric signals are admitted to DCS I/O switch boards 14, and DCS I/O switch boards 14 are according to every group
Three signals are compared, the negative pressure condition in a manner of two from three, determining garbage pool both sides；And DCS I/O switch boards
Garbage pool negative pressure signal is transferred to central control room 15 by 14, and central control room 15 then can show garbage pool by its terminal
Negative pressure condition；When garbage pool has one group of negative pressure to reach setting value Opa situation, the output control signal of DCS I/O switch boards 14,
Start control valve and connected blower fan, blower fan system starts, and garbage pool negative pressure declines immediately, and the foul smell in garbage pool is through work
Discharged after property charcoal adsorption tower；When garbage pool negative pressure drops to setting value -20pa, the output control signal of DCS I/O switch boards 14, control
Valve processed and connected blower fan are stopped, and ensure that foul smell is not excessive in garbage pool.
To sum up, for the utility model by above-mentioned structure design, solution the shortcomings of the prior art can be effective
Prevent that foul smell is excessive in garbage pool.
It is described above, only it is a kind of preferred embodiment of the utility model, not to technical scope of the present utility model
Impose any restrictions, every any trickle amendment made according to the technical essence of the utility model to above example, equivalent change
Change and modification, in the range of still falling within the utility model technology.
