Description
Technical field
The utility model relates to garbage-incineration smoke purifying technical field, specially a kind of incineration of refuse flyash stabilisation is matched
Expect control system.
Background technique
Incineration of refuse flyash is the substance that reheating recycling system after consumer waste incineration, flue gas purification system are collected,
Now, the processing disposition flying ash that has produced carried out mainly using cement solidification, lime curing technology, although this two
Curing/stabilizing technical treatment expense is lower, but after handling increase-volume than (up to 1.5~2.0) greatly, of poor quality, disposal costs are high,
And stability of the heavy metal in long-term disposal process is poor, and contains higher chloride ion in incineration of refuse flyash, uses
Cement solidification method processing must just carry out pre-treatment, to reduce chloride ion to the mechanical performance of building block after solidification and a later period huge sum of money
Belong to the problems such as influence that ion leaches, can thus greatly improve the standard built and run to flying dust disposal site, increase into
This, that is, limit the prolonged application of the processing method；
And the raising with people's environmental consciousness with the development of economy, should be for the processing of the following incineration of refuse flyash
With the raising of pollutant emission standard, what innoxious degree to be further increased, while processing and control two should be reduced as far as possible
The operating cost of secondary pollutant, then it is existing mostly to be handled using cement solidification, it is to select silicate chelating agent, cement as steady
Chemical drug agent is determined to handle city flying ash, main reasons is that: 1. increase-volume is than small, because being added to city using cement as medicament
In city's incineration of refuse flyash, the moisture content in flying dust is small, will affect the progress of hydrated reaction of cement, keeps aquation insufficient, so
Increase-volume is smaller；It is comparatively cheap raw material for the relatively various medicaments of cement, it is easy to obtain, and property 2. expense is low
Stablize；3. easy to operate, mainly mixing reacts it sufficiently, does not need the complicated steps such as melting, maintenance, there is very strong reality
With property, but existing technologies are low for the addition control precision of additive, cause increased costs.
Summary of the invention
Addition control precision additive in the processing of conventional garbage flying ash it is low and aiming at the problem that cause increased costs,
The utility model provides a kind of incineration of refuse flyash stabilisation batching control system, can be automatically adjusted according to flying dust treating capacity
The injection rate of additive, and measuring accuracy is high, and then improves stabilizing fly ash efficiency, saves cost.
Its technical solution is such that it includes blender, flying dust feed conveyer, cement feed conveyer, chelating agent
Delivery pump, it is characterised in that: it further includes PLC system, controller, and the PLC system is bi-directionally connected with the controller, described
Controller is separately connected the flying dust feed conveyer, cement feed conveyer, chelating agent delivery pump by frequency converter, described to fly
Grey feed conveyer, cement feed conveyer, chelating agent delivery pump connection weighing hopper are followed by the blender, with the weighing
The weighing sensor of bucket connection is communicatively connected to the controller.
It is further characterized by:
The model that the PLC system uses is S7-315-2DP；The controller is miniature using model DIN43700's
Controller, the frequency converter is equipped with 3, and divides with the flying dust feed conveyer, cement feed conveyer, chelating agent delivery pump
It does not connect not accordingly；The weighing hopper includes flying dust weighing hopper, cement weighing hopper, chelating agent weighing hopper, and is fed with the flying dust
The corresponding connection respectively of conveyer, cement feed conveyer, chelating agent delivery pump, the flying dust weighing hopper, cement weighing hopper, chelating
Agent weighing hopper is respectively connected with the weighing sensor.
The utility model has the beneficial effects that providing system operation after PLC system receives set amount signal to controller and referring to
It enables, controller can pass through the feed speed of Frequency Converter Control flying dust feed conveyer, cement feed conveyer, chelating agent delivery pump
Degree, and the signal of weighing sensor is received, correction is being made after relatively, automatic adjustment feed frequency reaches preset weight,
It is finally mixed into blender and is stirred, to ensure that feed precision, avoid the excessive injection of additive, save use
Cost, and can realize the purpose of continuous and quantitative production.
Detailed description of the invention
Fig. 1 is the work flow diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model includes that blender, flying dust feed conveyer, cement feed conveyer, chelating agent are defeated
Pump, PLC system, controller are sent, the model that PLC system uses is S7-315-2DP；Controller is using model DIN43700's
Microcontroller, PLC system are bi-directionally connected with controller, and corresponding connection flying dust feed is defeated respectively by 3 frequency converters for controller
Send machine, cement feed conveyer, chelating agent delivery pump, flying dust feed conveyer, cement feed conveyer, chelating agent delivery pump point
Flying dust weighing hopper, cement weighing hopper, chelating agent weighing hopper are not connected not accordingly to be followed by blender, are claimed with flying dust weighing hopper, cement
The weighing sensor (being not drawn into figure) that bucket, chelating agent weighing hopper accordingly connect again is communicatively connected to controller.
The course of work of the utility model is that PLC system calculates after receiving artificial settings amount signal and needs to put into
Flying dust, cement and chelating dosage, or be manually set need put into flying dust, cement and chelating dosage, and export to control
Device processed, and content of beary metal is detected, while providing system operating instructions, flying dust feed conveyer, cement to controller
Feed conveyer, chelating agent delivery pump start to be fed, and in order to guarantee to be fed precision, controller can be provided according to weighing sensor
Weighing feedback signal adjust automatically be fed frequency, reach feed setting value after, flying dust feed conveyer, cement feed conveyer,
Chelating agent delivery pump stops feed, while controller is to PLC system feedback system operating status；And controller can pass through frequency converter
The delivery rate of flying dust feed conveyer, cement feed conveyer, chelating agent delivery pump is controlled, and receives the anti-of weighing sensor
Feedback signal, after the two comparison, controller makes correction, ensure that feed precision, and in feed operation, controller is providing height
Fast signal reaches after being fed the 98% of set amount, and controller provides low speed signal again, after reaching feed set amount, controller hair
Stop feeding signal out, then passes through above-mentioned feed, metering, amendment, not only ensure that feed precision, avoid the excess of additive
Injection, saves use cost, and can realize the purpose of continuous and quantitative production.
