Bag filter dust collector with ultrasonic cleaning system and adaptive pressure control

Abstract

In this invention, a cubic bag dust collector with laboratory dimensions is designed. An ultrasonic transducer is installed on top of each bag, which produces ultrasonic waves with a frequency of 20 to 40 kHz and causes dust particles to be separated from the surface of the bag. The central control unit is based on an Arduino board, which, by receiving data from the pressure difference sensor, adaptively issues the ultrasonic activation command. In this way, cleaning is performed only when necessary and with the appropriate intensity. The cubic body design of the device allows for the installation of multiple filter bags simultaneously and is capable of being expanded to an industrial scale.

Description of the invention Note: Items must be written only inside [ ], otherwise they will not be reviewed. Title of the invention (as stated in the declaration) Bag filter dust collector with ultrasonic cleaning system and adaptive pressure control Technical background of the relevant invention The present invention is in the field of air pollution control technologies and industrial filtration systems and is specifically related to the design and manufacture of bag filters equipped with an ultrasonic cleaning system with adaptive pressure control. This technology is classified as an advanced system for separating suspended particles from a flow of polluting gases and, by utilizing ultrasonic waves and an intelligent differential pressure control algorithm, performs the process of removing particles from the surface of the bags without the need for compressed air flow and without stopping the filtration process. The main application of this technology is in industries with high pollution loads, including steel, cement, foundry, chemical and mining industries, where high particle collection efficiency, stable performance and reduced energy consumption are critical requirements for pollution control systems. Technical problem and stating the objectives of the invention Technical problem: Conventional methods of cleaning bag filters, such as jet pulse or mechanical agitation, result in high energy consumption, rapid bag wear, the need for expensive compressors, and periodic shutdowns. Objectives of the invention: 1. Reducing the energy consumption of the dust collection system 2. Increase the useful life of filter bags 3. Eliminates the need for compressed air compressors and high-wear parts 4. Possibility of continuous cleaning (Online Cleaning) without stopping the process A description of the state of the prior art and the history of developments related to the claimed invention. Bag filters have been introduced as one of the most widely used methods for controlling particulate matter since the 1950s. Over the years, methods such as mechanical agitation, reverse flow, and compressed air pulse cleaning have been developed. Despite the effectiveness of these methods, problems of pressure drop, high energy consumption, and reduced bag life have always been reported. In recent research, the use of ultrasonic technology for cleaning filters has been proposed, but so far, an industrially applicable model with adaptive control has not been designed and commercialized. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention This invention relates to a cubic baghouse dust collector with an ultrasonic cleaning system designed to separate suspended particles from industrial and laboratory gas flows. The main innovation in this invention is the use of ultrasonic technology to increase cleaning efficiency and automatic adaptive control based on a pressure difference sensor. In this system, contaminated air first enters the cubic body of the dust collector through the inlet chamber (1). The gas flow containing dust particles enters the dust collector chamber and is directed towards a set of vertical filter bags (3). Each bag is made of heat and moisture resistant porous industrial fabric and is suspended inside the chamber. The polluted air flow enters the bags from the outside, solid particles settle on the outer surface of the fabric, clean air passes through it, and the clean air is directed to the outside environment through the outlet (2). Over time, the accumulation of dust on the surface of the bag increases the pressure drop and reduces efficiency. To solve this problem, a cleaning system has been designed in such a way that the ultrasonic transducer system (4) is automatically activated at specific intervals after receiving a command from the adaptive pressure control device and ultrasonic waves are blown into the bags from the nozzles. The sudden shock caused by the waves causes the bag to vibrate momentarily and the dust layer to separate from its outer surface. The cleaning system produces these ultrasonic waves (ultrasound) with a frequency between 20 and 40 kHz. As mentioned, the vibration waves are transmitted to the fabric wall of the bag and, by creating tiny vibrations on its surface, they separate the adhering dust particles. This unique feature allows the bags to be cleaned continuously and effectively without the need for air pressure and compressor or stopping the process. The activation of this system is carried out by the central control unit (8) which is designed based on the Arduino board. By receiving data from the pressure difference sensor (5), this unit calculates the pollution load on the filters in real time and adaptively issues the command to activate the ultrasonic waves. In this way, the system only starts cleaning when the pressure drop exceeds the set value, thereby reducing energy consumption and increasing the life of the filters. The separated dust particles (6) fall down from the surface of the bags and accumulate in the dust collection funnel (7). At the end of the funnel, a discharge valve is installed to release the collected materials so that they can be periodically discharged or recycled. The device body is designed in a cubic shape to allow the installation of multiple filter bags in a modular manner. This structure is easily expandable to an industrial scale, so that the purification capacity can be increased in proportion to the inlet gas flow rate by adding additional filter modules. All components of the device are designed to be sealed and detachable for easy maintenance. Overall, this invention, by combining ultrasonic technologies and adaptive pressure control, significantly increases the efficiency of the filtration system, reduces energy consumption, and enables simultaneous use on a laboratory and industrial scale. Explanation of shapes, maps and diagrams Figure 1 shows an overview of the structure and operation of this bag filter dust collector with an ultrasonic cleaning system and adaptive pressure control. By utilizing ultrasonic wave technology and adaptive pressure control, it increases efficiency, reduces energy consumption, and enables continuous operation without the need for a compressed air system. A clear and precise statement of the advantages of the claimed invention over prior inventions. Reduces energy consumption by up to 30% compared to the Jet Pulse method Double the life of bags Eliminates compressors and costly peripherals Continuous cleaning capability without stopping the system Possibility of scaling to industrial dimensions Description of at least one implementation method for implementing the invention First, the device is assembled by installing the bags and transducers. The Arduino board is connected to the differential pressure sensor and the ultrasonic driver. During operation, when ΔP increases above the threshold value, the control unit commands the ultrasonic activation and the separated particles are transferred into the hopper. This process continues continuously and without stopping. Explicit mention of the industrial application of the invention Use in cement, steel, mining, foundry, chemical and other industries with suspended dust to control air pollution.
