Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The present application may be implemented based on a terminal having data processing capabilities, which may be a waste disposal system that may include an incinerator, a grate, a pusher, a waste grab, a blender, and a waste bin for storing solid inventory waste of a planned throughput.
The fire grate conveys garbage and ash slag through the hearth of the incinerator, materials are stirred and mixed, and primary air entering below the fire grate smoothly passes through the combustion layer. Under the action of the pusher, the mixed garbage can move from the waiting burning zone to the burning zone and finally reach the burning zone. The garbage grab bucket can be used for grabbing solid stock garbage in a garbage warehouse, and the stirrer can stir the mixed solid stock garbage and household garbage.
Next, as described in connection with fig. 1, the method for processing solid stock waste of the present application may include the steps of:
step S110, grabbing a plurality of solid stock garbage from a garbage warehouse through a garbage grab bucket, placing the solid stock garbage in a waiting area of an incinerator, grabbing a plurality of household garbage from an existing household garbage warehouse through the garbage grab bucket, and placing the household garbage in the waiting area of the incinerator.
Wherein the weight ratio of the solid stock garbage in the waiting area is not lower than the preset blending proportion.
Specifically, the preset blending ratio may represent a blending ratio for improving the solid stock garbage incineration efficiency, and the preset blending ratio may be customized, for example, 50% -80%. The waiting area may represent a waiting area in the incinerator that is being queued for transport to the combustion area, where refuse in the waiting area may be pushed by the pusher to the combustion area.
It can be understood that when the weight ratio of the solid waste in the waiting area is not lower than the preset blending ratio, the mixed solid waste and the household waste can have a higher incineration heat value than the incineration of the solid waste only, so that the mixed waste obtained by the mixing is incinerated, and the incineration efficiency is higher.
And step S120, layering, stirring and throwing the solid stock garbage and the household garbage in the waiting area by using a stirrer to obtain mixed garbage.
Specifically, the solid waste and the household waste are respectively paved by utilizing the stirrer to obtain the paved waste, the paved waste is stirred to obtain the stirred waste, and then the stirred waste is thrown, wherein the throwing times are not less than 2 times, the throwing height is not lower than two grab bucket positions of the waste grab bucket each time, the mixing state of the solid waste and the household waste can be monitored in the throwing process, and the mixed waste is obtained after the solid waste and the household waste are uniformly mixed.
And step S130, calculating the garbage conveying speed of the fire grate and the garbage feeding speed of the pusher according to the quantity of solid stored garbage in the current garbage warehouse and the planned treatment capacity.
The garbage conveying speed can be not lower than the default conveying speed of the fire grate, and the garbage feeding speed can be not lower than the default feeding speed of the pusher.
Specifically, the default conveying speed may represent a default operating speed of the grate before conveying the mixed garbage, and the default feeding speed may represent a default operating speed of the pusher before processing the mixed garbage.
It will be appreciated that since the solid waste of the planned throughput is required to be processed within a limited period of time, the amount of solid waste in the current waste bin and the planned throughput can be referenced to determine the waste conveying speed of the grate and the waste feeding speed of the pusher, thereby ensuring that the solid waste can be incinerated within the specified period of time.
And step S140, conveying the mixed garbage to an incinerator at the garbage conveying speed and the garbage feeding speed, and incinerating the mixed garbage by the incinerator to burn the mixed garbage in the waiting burning zone.
Specifically, in the process of mixed garbage incineration, the flame intensity, the fire wire position and the material layer thickness of the incineration can be monitored, so that the furnace temperature is prevented from being reduced due to the fact that the combustion condition of the mixed garbage is poor.
And step S150, judging whether solid stock garbage exists in the garbage warehouse or not when the mixed garbage does not exist in the waiting area, if so, returning to the step S110, and if not, executing the step S160.
It can be understood that the solid garbage in the garbage bin is huge in quantity, the solid garbage grabbed by the garbage grab is far less than the solid garbage in the garbage bin, and the garbage in the garbage bin needs to be grabbed by the garbage grab repeatedly/repeatedly for multiple times so as to perform multiple rounds of garbage incineration treatment. Then when there is solid stock waste in the waste bin and there is no mixed waste in the burn waiting area, step S110 may be returned to grasp the solid stock waste into the burn waiting area.
Step S160, determining that the solid stock garbage of the planned treatment capacity is completely burnt.
It will be appreciated that when there is no solid waste present in the waste bin, it may be indicated that the solid waste has been processed and it may be determined that the planned throughput of solid waste has been completely burnt.
According to the method for processing the solid stored garbage, the solid stored garbage is grabbed from the garbage warehouse through the garbage grab bucket, the solid stored garbage is placed in the waiting area of the incinerator, the household garbage is grabbed from the existing household garbage warehouse through the garbage grab bucket, the household garbage is placed in the waiting area of the incinerator, the proportion of the solid stored garbage in the waiting area is not lower than a preset blending ratio, the solid stored garbage and the household garbage in the waiting area are paved, stirred and thrown through the stirrer to obtain mixed garbage, the garbage conveying speed of the fire grate is calculated according to the quantity of the solid stored garbage in the current garbage warehouse and the planned processing quantity, the garbage conveying speed is not lower than the default conveying speed of the fire grate, the garbage conveying speed is not lower than the default feeding speed of the pusher, the mixed garbage is conveyed to the incinerator under the garbage conveying speed and the feeding speed, and is burnt until all the solid stored garbage is burnt by the mixed garbage, and the mixed garbage is recycled. Therefore, the solid garbage and the household garbage are mixed, so that the incineration efficiency of the mixed garbage obtained after mixing is increased, the running speeds of the fire grate and the pusher can be adjusted according to an incineration plan and the current garbage incineration process, the mixed garbage can be incinerated more efficiently, and the efficiency of incinerating the solid garbage is improved.
In some embodiments of the present application, the process of calculating the garbage conveying speed of the grate and the garbage feeding speed of the pusher according to the amount of solid garbage stored in the current garbage bin and the planned throughput in the step S130 is described, where the process may include:
s1, dividing the number of the solid stock garbage in the current garbage warehouse by the planned treatment capacity to obtain the proportion of the solid stock garbage to be burnt.
Specifically, the proportion of the solid waste to be burned may represent the progress of the solid waste to be treated.
S2, calculating a first accelerating proportion of the fire grate and a second accelerating proportion of the pusher based on the proportion of the solid garbage to be burnt and the current residual burning time.
Wherein the first rate of increase may represent a rate of increase to the operating speed of the grate and the second rate of increase may represent a rate of increase to the operating speed of the pusher.
Specifically, the first acceleration ratio and the second acceleration ratio may both be greater than 1.
More specifically, the process of calculating the first accelerating rate of the fire grate and the second accelerating rate of the pusher based on the proportion of the solid waste to be burned and the current residual burning time may include:
Calculating a first accelerating ratio of the fire grate and a second accelerating ratio of the pusher by using the following steps:
wherein x is the proportion of the solid garbage to be burned, y is the residual burning time, f 1 (x, y) is the first accelerating rate of the fire grate, f 2 (x, y) is the second speed increasing proportion of the pusher, alpha is the ageing sensitive index of the fire grate, beta is the ageing sensitive index of the pusher, and both alpha and beta can be greater than or equal to 0.
It can be understood that as the proportion of the solid waste to be burned increases, the first speed-up proportion of the fire grate and the second speed-up proportion of the pusher are enhanced, and as long as the solid waste to be treated exists, the first speed-up proportion of the fire grate is not lower than 112.78%, and the second speed-up proportion of the pusher is not lower than 126.82%. The first accelerating proportion of the fire grate and the second accelerating proportion of the pusher are enhanced along with the decrease of the residual incineration time, and the first accelerating proportion of the fire grate is not lower than 112.78 percent as long as the residual incineration time exists.
And S3, multiplying the first accelerating proportion by a default conveying speed to obtain the garbage conveying speed of the fire grate.
It will be appreciated that since the first rate of acceleration is greater than 1, multiplying the first rate of acceleration by the default conveying speed results in a greater value of the waste conveying speed than the default conveying speed, resulting in an increase in the operating speed of the grate.
And S4, multiplying the second accelerating proportion by the default feeding speed to obtain the garbage feeding speed of the pusher.
It will be appreciated that since the second ramp rate ratio is greater than 1, multiplying the second ramp rate ratio by the default feed rate results in a greater value of waste feed rate than the default feed rate, resulting in a higher operational speed of the pusher.
According to the solid stock garbage treatment method provided by the embodiment, the solid stock garbage to be burnt ratio is obtained by dividing the number of the solid stock garbage in the current garbage warehouse by the planned treatment amount, then the first accelerating ratio of the fire grate and the second accelerating ratio of the pusher are calculated based on the solid stock garbage to be burnt ratio and the current residual burning time, finally the first accelerating ratio is multiplied by the default conveying speed to obtain the garbage conveying speed of the fire grate, and the second accelerating ratio is multiplied by the default feeding speed to obtain the garbage feeding speed of the pusher, so that the accelerating of the fire grate and the accelerating of the pusher are more accurate.

s1, monitoring the dryness and humidity of a slag extractor in the process of incinerating mixed garbage by an incinerator.
It can be understood that the slag extractor can work normally under the condition of keeping humidity to normally slag, but when the slag extractor adheres to a large amount of dry ash granule, its humidity greatly reduced causes equipment to block easily, and even the part drops and damages the machine, consequently needs to monitor the dry humidity of slag extractor.
S2, when the dryness and humidity are lower than a preset humidity threshold value, water is injected into the slag extractor.
Specifically, the preset humidity threshold may represent a humidity threshold at which the slag tapping machine can effectively adsorb dry ash to maintain humidity.
Considering that the inorganic matter content in the solid waste is high, the incinerator can generate a great amount of slag in the process of incinerating the mixed waste mixed with the solid waste, and the slag is accumulated in a slag extractor, so that the slag extractor can be damaged.
On the basis, the method for treating the solid garbage provided by the application can further comprise the step of introducing a process for alarming when a slag extractor is detained with a large amount of slag, and the process can comprise the following steps:

S2, when the amount of the retained slag is larger than a preset slag retention threshold value, alarm information for processing the amount of the retained slag is sent to a slag management system through an abnormal alarm system.
Specifically, the preset slag retention threshold may represent an alert value of the slag scale. The alarm information may be sent to a slag plant system to inform slag plant personnel of timely presence to clear slag.
Considering that the incineration efficiency may be low due to insufficient incinerator fire during the process of incinerating mixed garbage, in some embodiments of the present application, the garbage disposal system mentioned in the foregoing embodiments is further described, and the garbage disposal system may further include a temperature monitor and a combustion supporting device in addition to the incinerator, the fire grate, the pusher, the garbage grab bucket, the stirrer and the garbage warehouse, so as to monitor the incinerator temperature during incineration.
On the basis, the method for treating the solid stock garbage provided by the application can further comprise the following steps:
s1, monitoring the upper layer temperature of a hearth of the incinerator through a temperature monitor in the process of incinerating mixed garbage by the incinerator.
And S2, adding the combustion-supporting device into the hearth when the upper temperature is lower than a preset temperature threshold value so as to improve the upper temperature.
Specifically, the preset temperature threshold may represent an incineration temperature at which there is a risk of decreasing the incineration efficiency, and the preset temperature threshold may be customized, for example, 880 ℃.
Considering that flammable and explosive gases, such as biogas, may exist in an environment where mixed garbage is burned, and the situation that gas explosion exists needs to be prevented, in some embodiments of the present application, the garbage disposal system mentioned in the foregoing embodiments is further described, where the garbage disposal system includes, in addition to an incinerator, a fire grate, a pusher, a garbage grab, a stirrer, and a garbage bin, a gas detector and an explosion-proof blower, so as to disperse the flammable and explosive gases through the explosion-proof blower, thereby preventing gas explosion, and reducing loss of equipment during gas explosion.
On the basis, the method for treating the solid stock garbage provided by the application can further comprise the following steps:
In the process of incinerating mixed garbage by the incinerator, if the gas detector detects that the concentration of methane in the garbage treatment system is greater than a preset methane concentration warning value, an explosion-proof fan is started to disperse the methane in the garbage treatment system.
Specifically, the preset biogas concentration warning value may represent a biogas early warning concentration value at which a biogas explosion risk exists.
It will be appreciated that when the concentration of biogas in the waste disposal system is greater than the preset biogas concentration warning value, it may be indicated that there is a risk of biogas explosion in the environment where the mixed waste is incinerated at this time, and then the anti-explosion blower may be started to disperse the biogas in the waste disposal system to prevent the biogas explosion to the maximum extent.
