The following describes the implementation of the present invention in detail with reference to specific embodiments.
Fig. 1 is a flow chart schematically illustrating a method for treating fly ash from waste incineration based on PH according to an embodiment of the present invention, which will be described in detail with reference to fig. 1.
A control method for waste incineration fly ash treatment based on a PH value comprises the following steps:
step S100: and acquiring weight information T1 and a PH value P1 of the raw ash after the waste incineration.
Specifically, the weight information T1 of the raw ash after the waste incineration is obtained by arranging the first weight sensor, and the pH value P1 of the fly ash after the waste incineration is obtained by arranging the first pH value sensor. Wherein, the raw ash after the garbage incineration is the fly ash after the garbage incineration. Before the first agent is added into the fly ash after the waste incineration, the weight of the fly ash is measured by adopting a weight sensor, and after the adding proportion of the first agent is determined, the adding amount of the first agent can be determined.
It should be noted that the weight information T1 of the raw ash after the waste incineration may be a specific numerical value, or may be an average value obtained by multiple measurements in a corresponding time period; the PH P1 may be a specific value or an average value measured over a corresponding period of time, and the PH measurement may be measured by a solid PH meter.
In one embodiment, multiple PH collection points may be provided in the fly ash processing system when the PH of the raw ash is measured, for example, when two collection points are provided, step S100 may be performed separately, that is, the two collection points perform the step independently, and obtain the PH measurement at the first collection point and obtain the PH measurement at the second collection point. Theoretically, when there are a plurality of sampling points, the PH measurement value may also be an average value of each sampling point, and still take two sampling points as an example, the step S100 may be executed to collect the PH measurement value of a first sampling point at a certain time period, collect the PH measurement value of a second sampling point at the same time period, calculate an average value of the PH measurement value of the first sampling point and the PH measurement value of the second sampling point, and use the average value as the PH measurement value. When the PH value measured value is the average value of the PH values in the corresponding time period, the problem that the adding proportion of the first medicament is not accurately calculated due to inaccurate single PH value measured value can be further avoided, and the accuracy of process adjustment is improved.
Step S200: calculating the adding proportion of the first medicament according to the weight information T1 and the PH value P1 of the raw ash, and controlling the adding amount of the first medicament; wherein, the first reagent and the raw ash are mixed and then react to obtain a first reaction product.
Specifically, the calculation formula of the addition ratio K of the first agent is:
K =K0+△K；
wherein the compensation value delta K = K1+ K0, the range of theoretical value K0 is 0-10%, the range of empirical value K1 is 0-2%, and P1 is the PH value of the raw ash.
Step S300: the weight information T2 and the pH P2 of the first reaction product were obtained.
Specifically, the weight information T2 of the first reaction product is acquired by providing the second weight sensor, and the pH P2 of the first reaction product is acquired by providing the second pH sensor. Before the second medicament is added into the first reaction product, the weight of the first reaction product is measured by using a weight sensor, and after the addition proportion of the second medicament is determined, the addition amount of the second medicament can be determined.
It should be noted that the weight information T2 of the first reaction product may be a specific value, or may be an average value obtained by measuring a plurality of times in a corresponding time period; the PH P2 may be a specific value or an average value measured over a corresponding period of time, and the PH measurement may be measured by a solid PH meter.
It can be understood that the method for detecting the PH value of the first reactant may adopt the method for detecting the PH value of the raw ash in step S100, and this embodiment is not described again.
Step S400: calculating the adding proportion of the second medicament according to the weight information T2 and the PH value P2 of the first reaction product, and controlling the adding amount of the second medicament; mixing the second agent with the first reaction product, and then carrying out secondary reaction to obtain a second reaction product; wherein the pH of the second reaction product is in the range of 8 to 10.
Specifically, the calculation formula of the addition ratio L of the second agent is:
L =L0-△L；
wherein the compensation value Δ L = L1+ L0, the theoretical value L0 ranges from 0 to 10%, the empirical value L1 ranges from 0 to 3%, and P2 is the PH of the first reaction product.
The control method for treating the waste incineration fly ash based on the PH value provides a control algorithm and a control strategy for adjusting the addition amount of the medicament according to the PH value of the fly ash, automatically adjusts the addition amount of the medicament by adjusting the PH value of the treated fly ash, exerts the synergistic adjustment effect of the solid medicament and the liquid medicament and ensures that the heavy metal chelation reaction of the fly ash is always in the optimal state. Compared with the prior art, the method has the advantages that the fly ash heavy metal chelation reaction is more accurate by controlling the pH value of the reactant, the accurate control on the fly ash treatment is realized, and a better treatment effect can be achieved.
In some embodiments of the present application, the first agent comprises baking soda, slaked lime, calcium dihydrogen phosphate, and calcium sulfate. After the first agent is mixed with the fly ash, hydroxide ions in the first agent can be combined with heavy metal ions in the fly ash to form a relatively stable solid compound. Such as lead hydroxide, cadmium hydroxide, zinc hydroxide, and the like.
The second agent is synthesized by chemical reaction of carbon disulfide, caustic soda flakes, ethanol and amine compounds, and the synthesized second agent comprises a sulfur-containing compound and an organic compound. Preferably, the amine compound may be diethyltriaminepentaacetic acid. It is understood that the kind of the sulfur-containing compound and the organic compound contained in the second chemical to be produced may be different depending on the kind of the amine compound to be used.
The following will further explain the control method for treating fly ash from waste incineration based on PH value in accordance with a specific example.
Referring to fig. 2, on the basis of the first embodiment, fig. 2 is a schematic flowchart illustrating a step S200 of a control method for treating fly ash from waste incineration based on PH according to a second embodiment of the present invention; it should be noted that, in this embodiment, the step S200 specifically includes the following steps:
step S201: comparing the PH value P1 with a preset theoretical value to obtain a deviation value;
step S202: comparing the deviation value with a preset value;
step S203: if the deviation value is larger than the preset value, an instruction for increasing the first medicament adding speed is sent out, and if the deviation value is smaller than the preset value, an instruction for reducing the first medicament adding speed is sent out.
Specifically, comparing the currently detected deviation value with a preset value stored in a database, and outputting a preset opening ratio of a first medicament adding valve corresponding to the stored preset value when the currently detected deviation value is judged to be matched with the stored preset value in the database; and when the current deviation value is judged to be larger than the preset value in the database, the opening proportion of the first medicament adding valve is adjusted step by step from the preset opening proportion by taking every 5 percent as a gear to reduce the opening proportion of the first medicament adding valve, an optimal adjustment proportion value is obtained during adjustment, and the optimal adjustment proportion value is stored in the database to update the database.
For example, if the current deviation value obtained in step S201 is 0.02, the valve adjustment command carries an opening adjustment ratio, and the opening adjustment ratio of the first medicament addition valve is 10%. If the obtained current deviation value is 0.025 and the numerical value does not obtain the matching data in the database, it indicates that the current deviation value is not stored, at this time, the steps S201-S203 are repeated after the adjustment from the opening adjustment proportion of 5%, if the obtained result is still in need of adjustment, the opening adjustment proportion is 10%, the adjustment and the detection are continued until a feedback result which is not in need of continuous adjustment is obtained, at this time, the obtained opening adjustment proportion is the first medicament adding valve opening adjustment proportion corresponding to the deviation value of 0.025, and the matched deviation value and the first medicament adding valve opening adjustment proportion are updated into the database in pairs.
It should be understood that the first medicament addition valve opening adjustment ratio refers to a ratio of the current opening to the adjustment initiation point opening.
Further, when the PH value shows abnormal or the first chemical adding valve is not adjusted in time, the first chemical adding valve still needs to be manually switched by a worker for adjustment, and for this reason, the method further includes:
