Description

Technical Field

[0001] The utility model relates to the technical field of dust removal and environmental protection, in particular to a dust removal controller. Background Art

[0002] As environmental pressures grow, the current dust removal project emissions need to be connected to online detection equipment, and the data collected by the equipment is connected to the Environmental Protection Bureau. The Environmental Protection Bureau can detect the emission data of the project in real time. When the emission does not meet the standard, it faces the risk of fines and suspension of production for rectification. The failure of bag dust removal to meet the emission standards is mostly related to bag damage. When using bag dust removal, each dust collector usually has dozens of chambers, and each chamber has hundreds of bags. During the dust removal process, the bags often leak dust, and the emission is connected to the network, which further compresses the time for dust bag detection and bag replacement.

[0003] At present, the market uses the method of detecting the pressure difference between the inside and outside of the dust collector bag or installing a dust sensor in the pipe or clean air chamber behind the dust collector bag to detect whether the bag is leaking. When the pressure difference or concentration is higher than the set value, it indicates that the dust collector bag has leaked. However, this method is limited by the changes in working conditions. The set reference value is an empirical value without theoretical basis. Moreover, this method can only roughly detect whether the bag is leaking or not, and cannot accurately locate which bag is leaking. Therefore, replacing the bag requires replacing the bag of the entire dust collector chamber, resulting in waste of resources and increased costs. In summary, it is necessary to invent a dust collector controller that can accurately detect damaged leaking bags and damaged locations. Utility Model Content

[0035] The control design adopts a guide rail shell design, and the interior is composed of upper and lower layers of circuit boards. The lower layer circuit is mainly the power part, and the top layer is the main control and display unit.

[0036] The main processor uses a 32-bit ARM processor core, which is combined with a real-time operating system to provide real-time control. The power input DC24V is converted into 5V and 3.3V for internal use. The valve drive part uses a high-speed power tube to achieve pulse output, and the analog acquisition interface uses a high-precision 16-bit AD chip to complete the acquisition. The digital acquisition interface uses an optocoupler isolation input to effectively reduce interference input. The communication interface is divided into RS485 and Ethernet interfaces for external communication, realizing the access of sensors with multi-protocol interfaces, the access of display units, the cascade use of equipment, and multi-point coordinated control. The top panel LED display unit can display the current operating status of the controller and the status of each input and output interface. The top circuit board is equipped with a dip switch for parameter setting of the equipment.

[0037] The controller adopts a standard 5.08MM plug-in terminal interface, which is flexible to plug and unplug, providing convenient conditions for maintenance and installation.

[0038] The pulse drive module is connected to the rapper, the blowing valve and the offline valve respectively, and the rapper, the blowing valve and the offline valve are arranged in the dust removal chamber;

[0039] The analog quantity acquisition module is connected to the bag leakage detection device; the bag leakage detection device includes a dust concentration sensor and a fluorescent powder adding device; the dust concentration sensor is arranged in the clean air chamber of the dust removal chamber; the fluorescent powder adding device is arranged at the inlet pipe of the bag dust collector.

[0040] The digital quantity input acquisition module is connected to a fluorescence detector; the fluorescence detector is arranged in the dust removal chamber.

[0041] The communication module includes an RS485 unit and a network interface 2; the RS485 unit is connected to the touch screen 1, and the network interface 2 is connected to the multi-level link.

[0043] The working method of the utility model is as follows: the power module supplies power to the main processor, and the operator sends a dust removal command to the main processor through the touch screen or the multi-level link through the communication module. The main processor controls the spray valve to spray into the dust removal chamber through the pulse drive module. At this time, if the dust concentration sensor does not detect dust, it proves that the dust bag is not leaking. The spray is closed by the offline valve, and the dust removal is completed. If the dust concentration sensor detects dust, it means that the dust is leaking. At this time, the main processor controls the fluorescent powder adding device to start through the analog quantity acquisition module. The fluorescent powder adding device adds fluorescent powder to the front end pipeline of the dust collector, and uses the negative pressure at the front end of the dust collector to suck the fluorescent powder into the dust collector. After the fluorescent powder enters the dust collector, it passes through the bag at the position where the bag is damaged and enters the clean air chamber; the main processor controls the fluorescence detector to perform fluorescence detection through the digital quantity input acquisition module, and obtains which bag has a fluorescence gap, then it is concluded that the bag has a leak, and the specific leakage position, i.e., the fluorescence gap, can be obtained. After that, the spray is closed by the offline valve, and the leaking bag is manually replaced.
