The invention aims to solve the problems that in the prior art, the dedusting ash of an ash bin and an ash bucket in an ultrahigh-power electric arc furnace cannot be effectively cleaned, and production stop caused by environmental protection is influenced by frequent blockage of the dedusting ash, and provides an automatic dedusting process for steelmaking and dedusting of the ultrahigh-power electric arc furnace.
In order to achieve the purpose, the invention adopts the following technical scheme:
an automatic dust removing process for steel making and dust removal of an ultra-high power electric arc furnace comprises the following steps:
the method comprises the following steps: an electric hammer and a pneumatic hammer are arranged on the outer wall of the ash bin or the ash bucket, and the electric hammer and the pneumatic hammer are both remotely connected with a PLC control cabinet and an industrial personal computer;
step two: an operator controls an industrial personal computer, selects a full-automatic cyclic ash removal mode, adopts a human-computer interface of the industrial personal computer to send an instruction, and a PLC executes remote control on the electric hammer and the pneumatic hammer;
step three: an operator controls an industrial personal computer, selects a remote semi-automatic mode, can select manual start and stop on a human-computer interface aiming at a certain ash bin and an ash hopper with poor ash cleaning effect, and automatically beats the ash bin to clean ash by an electric hammer and a pneumatic hammer according to a preset frequency after the start;
step four: the operating personnel control industrial computer, the manual mode of operation of field operation case: and the field inspection worker switches to field control according to the checked ash removal condition, or is used during debugging after the maintenance is stopped during maintenance.
As a further preferable scheme, in the first step, the number of the electric hammers is 120, and the number of the pneumatic hammers is 12.
As a further preferable scheme, the ash removal time in the full-automatic circulating ash removal mode or the remote semi-automatic mode is 30min-40min, and the hammering frequency of the electric hammer and the pneumatic hammer is 45/min-120/min.
The automatic cleaning device has a simple structure, realizes automatic cleaning of the dust removed in the steelmaking of the electric arc furnace, reduces the burden of personnel, can ensure that the ash bin is unblocked constantly, ensures the environmental protection, ensures the continuity of the steelmaking production of the electric arc furnace, and has obvious environmental protection effect and economic benefit.
Detailed Description
The technical solution of the present invention is clearly and completely described below.
In order to avoid the problems that the blockage of dust removal ash and the damage of dust remover equipment caused by the incomplete ash removal of a vibrator and the blockage of an ash bin caused by the incomplete ash removal of an ash removal device by manual irregular ash removal, the labor intensity is high, the working environment is severe, the randomness is high, the incomplete ash removal still exists, and the blockage of the ash bin is easily caused, the novel ash removal process realizes the automatic complete ash removal, and particularly relates to an automatic ash removal process for steelmaking dust removal of an ultra-high power electric arc furnace:
the technical scheme is as follows: (1) the main process flow is as follows: dust-containing flue gas generated in the steel making process of the electric arc furnace → the bag-type dust collector separates the flue gas from dust → the fly ash enters the ash bin → the fly ash enters the ash bucket → the fly ash is discharged and transported out. (2) The main process equipment comprises the following steps: the device comprises an electric hammer, a pneumatic valve table, a scraper conveyor, a bucket elevator, an ash discharge valve, a PLC (programmable logic controller) control cabinet and an industrial personal computer. (3) An automatic ash removal process: the invention designs 3 control modes to realize automatic ash removal, wherein the first mode is as follows: the full-automatic circulation deashing mode adopts an industrial personal computer and a human-computer interface to send instructions, the PLC executes remote control on main process equipment such as the electric hammer and the pneumatic hammer to realize automatic deashing, and the human-computer interface can flexibly set the interval time of deashing at each time and the action frequency of the electric hammer and the pneumatic hammer so as to achieve the optimal deashing effect. And a second mode: in the remote semi-automatic mode, a manual start and stop can be selected on a human-computer interface aiming at a certain ash bin and an ash hopper with a poor ash cleaning effect, after the operation, the electric hammer and the pneumatic hammer automatically knock the ash bin to clean ash according to a preset frequency, and a main control operator confirms to click a stop button on a picture according to the ash cleaning effect. And a third mode: manual operation mode of the field operation box: and the field inspection worker switches to field control according to the checked ash removal condition, or is used during debugging after the maintenance is stopped during maintenance.
Each ash bucket on the human-computer interface is provided with a remote/local mode selection button, and the selection of remote is to perform a full-automatic ash removal mode according to the mode I; and if the local mode is selected, the remote semi-automatic ash removal mode is carried out according to the mode II, the local mode button is lightened (turned into green), the start buttons of the 1# -4 # hammers are clicked to remove ash one by one, and the ash removal stopping is clicked to finish.
Specifically, the number of electric hammers is 120, and the number of pneumatic hammers is 12.
Specifically, the ash removal time in the full-automatic circulating ash removal mode or the remote semi-automatic mode is 30-40 min each time, and the hammering frequency of the electric hammer and the pneumatic hammer is 45-120 times/min.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
