Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects of the invention are consistent.
As shown in Figure 1, in one embodiment of the invention, providing a kind of discharge control method, bin bottom is provided with
The double-deck blow-off valve, the described method comprises the following steps.
In step s101, grey magnitude currently stored in the feed bin is obtained.
In embodiments of the present invention, it can use the ash quantity detection being set on the test point position of different height in feed bin
Device measures the grey magnitude in feed bin, and grey amount detecting device can be level-sensing device, or temperature element is matched with temperature element
The fixation member used and the calculator for calculating temperature value are covered, temperature element can be thermocouple sensor or thermoelectricity
Sensor etc. is hindered, in practical applications, grey amount detecting device can be according to temperature of charge and ring at material-level measure point in feed bin
Temperature different principle in border reflects controlling level by way of directly measuring temperature indirectly, can also be fallen according to material
Average speed and time etc. calculate the grey magnitude stored in feed bin.
When determining grey magnitude in feed bin indirectly using temperature element, since the dust or material general speed of whereabouts will not
It is too fast, it is a slow process, at material rises to temperature element and when being detected high temperature, the material of rising generally will not
It is too many to be higher by temperature element, this height can be ignored completely, and even have the material accumulation higher than temperature element, for
This little material, as long as having enough spaces above temperature element, discharge, is not problem completely more a little later.Therefore right
When lag processing mode when temperature element is in test point position thermometric is exactly to install temperature element, above temperature element slightly
The space for staying a little height, since general temperature element can't be installed to top, so the height of the test point position can not
It is restricted.
In addition, because when discharge causes material to hurtle down, if temperature element reacted slow, it may appear that material is low
In the also not reaction in time of many temperature of temperature measuring point, it is likely that material can be emptied, influence the leakproofness of blow-off valve, so should
The temperature element of high sensitivity is used as far as possible.
In this step, the temperature value of available temperature element measurement, temperature value and preset temperature threshold are compared
Compared with, when be higher than temperature threshold when, can determine that material position reaches at test point position, and then can be according to the material at test point position
Holding capacity of bin calculates grey magnitude.
For example, it is assumed that preset temperature threshold is 50 DEG C, when the grey amount detecting device output temperature for being located at test point position is high
When preset temperature threshold values is 50 DEG C, it can determine that the controlling level of material in feed bin reaches test point position, here default
What what threshold values can detect for a long time according to test point position where live temperature element detected when material reaches at the position
Temperature, the result of ambient temperature data observation are configured.
In step s 102, judge whether the currently stored grey magnitude is equal to default grey magnitude.
In embodiments of the present invention, the default grey magnitude can be according between the upper valve plate and lower valve plate of the blow-off valve
The capacity of stocking space determine, that is to say, that default ash magnitude can be contained according to blow-off valve upper layer charge cask
Inventory determines.
In practical applications, the position setting at least one of the capacity of upper layer charge cask can be doubled on feed bin side wall
At least one detection point is arranged in a test point position, the position that the capacity of upper layer charge cask is twice on feed bin side wall
It sets, at least one test point position is arranged in the position that the capacity of upper layer charge cask is three times on feed bin side wall, and so on,
For example, the test point position of position 1 of the capacity of upper layer charge cask can be doubled on feed bin side wall, on feed bin side wall
It is twice in the test point position of position 5 of the capacity of upper layer charge cask, can specifically be set according to actual needs, accordingly
Ground, the corresponding default grey magnitude in each test point position is not also identical, is set at the capacity for being doubled in upper layer charge cask
The corresponding default grey magnitude in test point position be one times upper layer charge cask capacity, be set to and be twice in upper layer charging and hold
The capacity, etc. for the upper layer charge cask that the corresponding default grey magnitude in test point position at the capacity of device is two times, each
The multiple grey amount detecting devices of the position setting of the integral multiple of the capacity of upper layer charge cask can reduce a certain ash quantity detection to the greatest extent
Measurement error caused by plant failure, the case where avoiding the mistake open and close for controlling the double-deck blow-off valve.
In this step, the grey magnitude that can be calculated is compared with default grey magnitude, when the two is equal, can be determined
Currently stored grey magnitude is equal to default grey magnitude.
When the currently stored grey magnitude is equal to default grey magnitude, in step s 103, generates discharge and control signal.
In embodiments of the present invention, discharge control signal can refer to that control blow-off valve starts the control letter of a discharge movement
Number, the control program that control blow-off valve carries out discharge movement can be a set of independent discharge program, general discharge control process
It is as follows: to can control the upper valve plate of unlatching first, at this moment material is fallen in the vessel space of blow-off valve upper layer；Wait preset time period
Afterwards, such as 2 seconds etc., it can control the upper valve plate of closing；After the closing of upper valve plate, unlatching lower valve plate can control；At this moment due under
Valve plate is opened, it is possible to outside discharge predetermined amount of time, such as 2 seconds etc., it then can control closing lower valve plate, at this moment discharge
Terminate, and so on.
In practical applications, discharge control signal can be used as the input of the control program of discharge movement, for example, working as discharge
When control signal is " 1 ", the control program of discharge movement can be executed, it, can not the row of execution when discharge control signal is " 0 "
The control program etc. of material movement.
In step S104, discharge control signal is sent to the double-deck blow-off valve, so that the bilayer discharge
Valve controls discharge movement of signal enabling according to the discharge.
This method provided in an embodiment of the present invention, can be according to the pass of grey magnitude and default grey magnitude in current feed bin
System, the discharge that the discharge movement of starting of control blow-off valve can be generated when material is identical as default ash magnitude control signal,
It realizes and presses Level control bin bottom discharge valve events, just carry out discharge when reaching target material position, improve discharge control
Discharge when accuracy, the i.e. discharge, is more energy-saving and environmentally friendly.
In another embodiment of the present invention, the method also includes following steps.
When the currently stored grey magnitude is not equal to default grey magnitude, in step s 201, judge described currently to deposit
Whether the grey magnitude of storage is less than default grey magnitude.
When currently stored grey magnitude is less than default grey magnitude, in step S202, returns and execute described in the acquisition
In feed bin the step of currently stored grey magnitude.

The current grey magnitude of constant testing, convenient for determining the grey magnitude in feed bin in real time.
In another embodiment of the present invention, the method also includes following steps.
When the currently stored grey magnitude is not equal to default grey magnitude, in step S301, judge described currently to deposit
Whether the grey magnitude of storage is greater than default grey magnitude.
When the currently stored grey magnitude is greater than default grey magnitude, in step s 302, according to described currently stored
Grey magnitude calculation discharge number.
In embodiments of the present invention, the currently stored grey magnitude and the double-deck blow-off valve upper layer can be calculated first
Multiple proportion between the capacity of stocking space, for example, grey magnitude is 2 times or 3 times etc. of the capacity of upper layer charge cask, so
The discharge number is determined according to the multiple proportion afterwards, for example, corresponding discharge number can be 2 when multiple is 2 times
Secondary, when multiple is 3 times, discharge number is corresponding can be inferior for 3.
Discharge can refer to the discharge movement of control blow-off valve, and general discharge control process is as follows: first can be with
Upper valve plate is opened in control, and at this moment material is fallen in the vessel space of blow-off valve upper layer；After waiting preset time period, such as 2 seconds etc., it can
Upper valve plate is closed with control；After the closing of upper valve plate, unlatching lower valve plate can control；At this moment since lower valve plate is opened, so can
With outside discharge predetermined amount of time, such as 2 seconds etc., closing lower valve plate then can control, at this moment discharge terminates, and so on.
In step S303, generates discharge corresponding with the discharge number and control signal.
In step s 304, discharge control signal is sent to the double-deck blow-off valve, so that the bilayer discharge
Valve controls signal enabling multiple discharge corresponding with discharge number according to the discharge and acts.
In embodiments of the present invention, the double-deck blow-off valve starts corresponding with discharge number after receiving discharge control signal
The movement of multiple discharge, for example, when the discharge number in discharge control signal is 2 times, then the discharge of the double-deck blow-off valve starting
The number of movement is also 2 times, and when the discharge number in discharge control signal is 3 times, then the discharge of the double-deck blow-off valve starting is dynamic
The number of work is also 3 inferior.
Certainly, the mode of this continuous multiple discharge of starting is to be carved with the case where a large amount of material is fallen when being directed to a certain,
Rather than material slowly falls always the case where being gradually accumulated, because under normal circumstances when dust stratification amount charges equal to unloading valve
It is primary just to start discharge when space, without using multiple marker method, because when the material mistake by slow dust stratification process collection
When mostly without arranging, bottoms material is easy cooling, and block is easy if containing aqueous vapor in flue gas, material is easy to cause to be difficult to arrange
Out.
In step S305, after the movement of multiple discharge, return currently stored in the execution acquisition feed bin
Grey magnitude the step of.
This method provided in an embodiment of the present invention, can grey magnitude in feed bin be that the upper layer of the double-deck blow-off valve charges and holds
When the several times of the capacity of device, the corresponding number for determining discharge movement be can be avoided again due to discharge is not discharged causes
Stuck, the case where leaking out.
In another embodiment of the present invention, the step S101 includes the following steps.
In step S401, the multiple ash quantity for being respectively arranged at multiple and different test point positions on the feed bin side wall are obtained
The temperature value of detection device acquisition.
In embodiments of the present invention, the height of multiple different test points positions is different.
In step S402, the temperature value greater than preset temperature threshold is judged whether there is.
When there is the temperature value for being greater than the preset temperature threshold, in step S403, determine described in all be greater than
The corresponding test point position of the temperature value of preset temperature threshold.
In step s 404, it is calculated according to the maximum test point position of the height determined currently stored in the feed bin
Grey magnitude.
This method provided in an embodiment of the present invention, the temperature value that can be exported automatically according to grey amount detecting device judge material position
The test point position for whether reaching grey amount detecting device achievees the purpose that detect material position height, and then is convenient for pressing Level control material
