Description
Technical field
The present invention relates to electrical control and instrument measurement fields, specifically, the present invention relates to a kind of coal dedusting coolings
The explosion-proof warning device in advance in storehouse.
Background technique
The common cleaner in coking of coal field when dust removal blower of coke oven, coke oven dust are made of two independent systems,
It is that coke oven discharges of the coke and coal craft dust removal respectively, is respectively equipped with independent dedusting fan, wherein the control of coal technique dust pelletizing system
Mode processed are as follows: the instruction of coal dedusting fan high speed signal is arrived, but the inactive high speed of practical upper fan, but very valve has closed at this time
Close, cooling storehouse assembles a large amount of raw coke oven gas under the operating condition of low speed air quantity, if operative employee find correct processing not in time, when blower again
Restarting high speed, air duct can be mingled with Mars and enter cooling storehouse, mix with the raw coke oven gas in storehouse and be easy to set off an explosion.
Two kinds with the low speed and at a high speed revolving speeds operations of coal blower (low speed is 20% at full capacity, is at a high speed 80% at full capacity,
Normal blower low speed reaches high speed and needs 90S)；How to judge that coal blower instructs then in high speed signal, practical rotation speed of fan
There is key point of the low speed to high-speed mobile trend for the method.
Summary of the invention
The revolving speed that the technical problem to be solved by the present invention is to be measured by practical blower when blower high speed instruction reaches
With the comparison of the rotation speed of fan of setting, judgement when the pass very valve and when the alarm.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that: a kind of coal dedusting cooling storehouse is explosion-proof
Warning device in advance, including blower, tachometer of measuring, revolving speed display instrument, revolving speed comparator one and revolving speed comparator two, described turn
The revolving speed of the front measurement blower of blower is arranged in fast measuring instrument, and tachometer of measuring passes through conducting wire and revolving speed display instrument, rotating ratio
It is connected compared with instrument one and revolving speed comparator two, the revolving speed comparator one is connect by conducting wire with coal very valve, revolving speed comparator
Two are connect by conducting wire with alarm lamp.
The explosion-proof warning device application method in advance of this coal dedusting cooling storehouse, includes the following steps:
A: if revolving speed comparator one confirms that blower is high-speed rotation, rotation speed of fan reaches setting speed at this time, begins to shut off non-
Normal valve, coal vehicle can normal coals；
B: if revolving speed comparator one confirms that blower is not up to high speed, coal very valve is always maintained at opening state, so that it is guaranteed that
Without raw coke oven gas in cooling storehouse, prevent from exploding；
C: when blower runs at high speed, revolving speed is not up to setting value, and the revolving speed that revolving speed comparator two is actually measured after 30 seconds is not up to
Setting value, dedusting control system start to alarm, and operative employee is reminded to carry out emergent management.
Using technical solution of the present invention, can obtain it is below the utility model has the advantages that
The explosion-proof warning device in advance of coal dedusting cooling storehouse of the invention, if revolving speed comparator one confirms that blower is that high speed turns
Dynamic, rotation speed of fan reaches setting speed at this time, begins to shut off very valve, and coal vehicle can normal coal；If revolving speed comparator
One confirmation blower is not up to high speed, and coal very valve is always maintained at opening state, so that it is guaranteed that preventing in cooling storehouse without raw coke oven gas
Explosion；When blower runs at high speed, revolving speed is not up to setting value, and the revolving speed that revolving speed comparator two is actually measured after 30 seconds is not up to
Setting value, dedusting control system start to alarm, and operative employee is reminded to carry out emergent management.
Detailed description of the invention
Brief description is made to content expressed by each attached drawing of this specification and the label in figure below:
Fig. 1 is the structural schematic diagram that this shifts to an earlier date warning device；
Label in above-mentioned figure is equal are as follows: 1, blower；2, tachometer of measuring；3, revolving speed display instrument；4, revolving speed comparator one；5, revolving speed
Comparator two；6, coal very valve；7, alarm lamp.
Specific embodiment
Below against attached drawing, by the description of the embodiment, to for example related each structure of a specific embodiment of the invention
The works such as the shape of part, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle are further
Detailed description.
As shown in Figure 1, the explosion-proof warning device in advance of this coal dedusting cooling storehouse includes blower 1, tachometer of measuring 2, revolving speed
The front measurement blower 1 of blower 1 is arranged in display instrument 3, revolving speed comparator 1 and revolving speed comparator 25, tachometer of measuring 2
Revolving speed, tachometer of measuring 2 are connect by conducting wire with revolving speed display instrument 3, revolving speed comparator 1 and revolving speed comparator 25, rotating ratio
It is connect by conducting wire with coal very valve 6 compared with instrument 1, revolving speed comparator 25 is connect by conducting wire with alarm lamp 7.
The explosion-proof warning device in advance of this coal dedusting cooling storehouse uses step are as follows:
A: if revolving speed comparator 1 confirms that blower 1 is high-speed rotation, 1 revolving speed of blower reaches setting speed at this time, begins to shut off
Coal very valve 6, coal vehicle can normal coals；
B: if revolving speed comparator 1 confirms that blower 1 is not up to high speed, coal very valve 6 is always maintained at opening state, thus really
It protects in cooling storehouse without raw coke oven gas, prevents from exploding；
C: when blower 1 runs at high speed, revolving speed is not up to setting value, and the revolving speed that revolving speed comparator 25 is actually measured after 30 seconds does not reach
To setting value, dedusting control system starts to alarm, and alarm lamp 7 is lighted, and operative employee is reminded to carry out emergent management.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
