Detailed Description
A method for detecting the damage of a dust removal cloth bag comprises the following steps:
and S1, confirming that the cloth bag needs to be checked according to the condition that the dust at the outlet of the coal discharge fan exceeds the standard.
And S2, opening the big cover, closing the lifting valve cover and isolating other air chambers.
S3, the interphone contacts an operator to open the air inlet valve of the cloth bag box, and the interphone visually inspects whether dust-mixed black gas is discharged from each cloth bag of the air chamber, so that whether a leakage point exists can be accurately determined.
S4, checking each working chamber of the cloth bag box in sequence, and counting the cloth bag replacement condition.
S5, when the cloth bag is pulled out, the coal discharge fan is started in a linked mode, the system generates negative pressure (the pressure cannot be too high, the flow rate of the coal discharge fan is controlled to be about 40000m3/h, so that on-site dust is removed, the emission standard of less than 10mg/m3 is guaranteed), the coal dust attached to the surface of the cloth bag is removed, and the dust on the operation site is avoided.
As shown in fig. 1, the principle of investigation of the present invention:
filling a certain amount of gas into the cloth bag box body, filtering dust by the cloth bag if the cloth bag is not damaged, and blowing out the smoke through the cloth bag outlet to obtain clean gas; when a damaged cloth bag is encountered, the gas carrying coal powder enters the cloth bag from the damaged point of the cloth bag and is discharged through the cloth bag outlet, black dust-mixed smoke is visible, namely the breakage of the cloth bag is determined, and the accuracy rate of detecting the cloth bag is improved from 70% to 100%.
As shown in figure 2, when the cloth bag is replaced, the negative pressure of the system is reduced by using self-made special tools (a crowbar 1 and a T-shaped hook 2) and simultaneously starting the coal discharge fan, so that the dust is reduced, the cloth bag replacement time is shortened, and the average time per cloth bag is shortened by 20 minutes. The specific operation process is as follows:
before the faceplate 4 is disassembled, a fastening faceplate screw in the fastening faceplate screw hole 5 is taken down;
the frameworks 3 which are made into the cloth bags are pulled out one by one, when the self-made hooks 2 are used for operation, the length of the hooks 2 is utilized to facilitate the operation of operators, the range of the action of squatting and standing is reduced, so that the working strength is reduced, the pollution caused by close-distance contact of raised dust is reduced, and in addition, compared with the original mode of pulling the frameworks out by fingers, the frameworks are pulled out by the hooks, the fingers are effectively protected, and the operation efficiency is improved;
the crowbar 1 is inserted into the fastening screw hole 5 and is used as a fulcrum to press the crowbar downwards, the faceplate 4 can be pried up easily by utilizing the lever principle, and the labor is saved and the operation is fast;
after the flower disc 4 is taken out, the damaged cloth bag pressed at the lower part of the flower disc 4 is taken out and then is put into a new cloth bag.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
