Description
Technical Field
The utility model discloses an automatic dehumidifying device of a dust remover steam drum based on PLC control, and relates to the technical field of bag type dust remover dust removal.
Background
The dust remover is a common device for removing dust from flue gas in factories, the dust remover mainly filters dust in the flue gas through the filter bag, when the filter bag is used for a period of time, a large amount of dust can be accumulated on the outer side of the filter bag, and most of dust attached to the filter bag can be removed by periodically blowing the filter bag from the inner side by compressed air. Compressed air of the dust remover firstly enters the steam drum through the jetting pipe, and then is distributed to each jetting branch pipe through the steam drum. The drum plays an important role in the compressed air injection system for storing compressed air and for distributing the air source. In the use, because compressed air can't accomplish absolutely dry, can cause the moisture that slowly accumulates in the steam pocket, the gas humidity of follow steam pocket jetting is too big, can cause the filter bag outside dust to adhere to on the filter bag because the moisture can not clear up, influences the dust removal effect of dust remover, serious can cause the filter bag to damage, only can make the dust remover normal operating through shut down the change filter bag. It is therefore very important and urgent to monitor the humidity of the compressed air in the drum and automatically dehumidify.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-2, the automatic dehumidifier of dust remover steam drum based on PLC control, including the steam drum, jetting branch pipe and blast pipe are connected simultaneously to the steam drum, be equipped with entry solenoid valve and blowdown solenoid valve on jetting branch pipe and the blast pipe respectively, still install pressure sensor and humidity transducer on the steam drum, pressure sensor, humidity transducer, entry solenoid valve and blowdown solenoid valve respectively with PLC controller electric connection, PLC controller still with acousto-optic device and control panel electric connection, control panel is equipped with man-machine interaction interface, man-machine interaction interface is used for showing the numerical value that pressure sensor, humidity transducer feedback signal correspond, can show the operating condition of entry solenoid valve and blowdown solenoid valve simultaneously to can realize manual control.
The controller is installed in the control cabinet, and the control panel is installed on the control cabinet in an embedded mode. The number of the steam drums is multiple, the steam drums are connected with a blowing main pipe through blowing branch pipes, and the blowing main pipe is connected with a compressor.
The working principle of the utility model is as follows:
in the daily operation process, the signals of the humidity sensor and the pressure sensor are transmitted to the PLC. When the humidity value of a certain steam drum exceeds the set value of the PLC, the PLC sends out an exhaust signal to control the blow-down electromagnetic valve to be opened for exhaust, and simultaneously, the inlet electromagnetic valve is closed.
When the pressure value reaches a set value, the PLC controller sends out a gas storage signal to control the pollution discharge electromagnetic valve to be closed and the inlet electromagnetic valve to open so that compressed air enters the steam drum.
The humidity sensor continuously detects the humidity condition in the steam drum, and if the humidity in the steam drum is recovered to be normal, the PLC controller does not send corresponding exhaust and gas storage signals. If the humidity of the steam drum is still higher, the PLC controller executes the exhaust and gas storage program again.
If the humidity of the steam drum is higher after a plurality of times of exhausting and storing operations by the PLC, the PLC sends an alarm signal to send out an audible and visual alarm to the audible and visual device, and the operation and maintenance personnel are reminded to go to the site for checking and maintenance. The times of the exhaust and gas storage operation, the humidity value and the set value of the pressure sensor can be set on a man-machine interaction interface.
The utility model realizes unattended operation in the daily operation process without manual operation. The operation and maintenance personnel can observe the operation parameters through a man-machine interaction interface, can also realize manual operation, and can modify the program set values in real time according to the field conditions. The utility model can effectively avoid the phenomenon of dust attachment of the cloth bag of the dust remover caused by high humidity of the steam drum, reduce the condition of damage of the filter bag due to humidity and improve the dust removing efficiency of the dust remover; personnel, equipment and economic losses caused by filter bag wetting problems and secondary problems are avoided, and the safety of the whole production operation process and the stability of the whole production system are protected.
Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
