Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to an anti-blocking and cleaning device for flue gas desulfurization equipment. Background Art

[0002] Coal-fired flue gas contains a large amount of pollutants such as sulfur dioxide and dust; and the limestone-gypsum wet flue gas desulfurization technology is the most mature desulfurization process at present, and has become the preferred technology for flue gas desulfurization in thermal power plants at home and abroad. For thermal power units burning high-sulfur coal, since the sulfur dioxide concentration in the flue gas before entering the desulfurization device is very high, the desulfurization reaction absorption tower generally needs to adopt a larger slurry spray volume and an enhanced liquid-gas mass transfer device (such as a tray, coupling device, etc.); Therefore, while ensuring a strong desulfurization capacity, the high-sulfur coal flue gas desulfurization device generally has the disadvantages of high flue gas resistance, high system power consumption, and a single energy-saving adjustment method. In addition, the fresh limestone slurry of the existing desulfurization absorption tower almost directly enters the slurry pool, and does not fully utilize the high-purity, high-PH value limestone slurry. If the fresh limestone slurry is first in contact with the flue gas, the desulfurization efficiency can be improved;

[0003] After a certain period of use, a large amount of reactants will be produced by the reaction in the desulfurization absorption tower. The concentration of the limestone slurry in the desulfurization absorption tower will become higher and higher, and at the same time, more and more solids will appear at the bottom. Therefore, it is often necessary to shut down the equipment regularly and have the operator enter the absorption tower for cleaning. On the one hand, this reduces production efficiency, and on the other hand, entering the absorption tower does great harm to the operator's body. Utility Model Content

[0004] The utility model aims to provide an anti-blocking cleaning device for flue gas desulfurization equipment, which has the characteristics of simple operation, time and labor saving, improved cleaning efficiency and strong versatility.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-blocking and cleaning device for flue gas desulfurization equipment, comprising a tower body and a support plate located above the tower body, a mounting plate is arranged below the support plate, a screw rod is rotatably connected to the left side of the lower end surface of the mounting plate, a slide rod is fixedly connected to the right side of the lower end surface of the mounting plate, a mounting ring is movably connected to the outer walls of the screw rod and the slide rod, an ultrasonic generator is installed on the upper end surface of the mounting ring, a transducer is installed on one side of the ultrasonic generator, a knife seat is arranged on the outer wall of the transducer, a scraper is fixedly connected to the outer wall of the knife seat, and a plurality of evenly distributed nozzles are arranged on the outer wall of the mounting ring.

[0006] In order to facilitate the winding of the water pipe, as a preferred anti-blocking and cleaning device for flue gas desulfurization equipment of the utility model, an electric reel is installed on the upper end face of the mounting plate, and the water pipe is wrapped around the outer wall of the electric reel. The other end of the water pipe passes through the mounting plate and is connected to the inside of the mounting ring.

[0007] In order to facilitate the introduction of an external water source, as a preferred anti-blocking and cleaning device for flue gas desulfurization equipment of the utility model, a water pump located on one side of the electric reel is installed on the upper end surface of the mounting plate.

[0008] In order to drive the screw to rotate, as a preferred anti-blocking and cleaning device for flue gas desulfurization equipment of the utility model, a motor is installed on the upper end surface of the mounting plate, and the output end of the motor is fixedly connected to the screw.

[0009] In order to drive the mounting plate to rotate, as a preferred anti-blocking and cleaning device for flue gas desulfurization equipment of the utility model, the bottom end of the support plate is rotatably connected to a rotating shaft, the bottom end of the rotating shaft is fixedly connected to the mounting plate, and the top end of the rotating shaft extends to the top of the support plate and is fixedly connected to a rotary valve.

[0010] In order to facilitate observation of the internal conditions of the tower body, as a preferred anti-blocking and cleaning device for flue gas desulfurization equipment of the utility model, two observation doors are provided on the upper end surface of the support plate.

[0011] In order to match the inner wall of the tower body, as a preferred anti-blocking and cleaning device for flue gas desulfurization equipment of the utility model, the scraper is an arc-shaped structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When cleaning the inside of the tower body, one end of the water pipe is connected to the water pump, and the other end is connected to the external water source. The water pump is started, and water is introduced into the inside of the installation ring through the water pipe and sprayed out through multiple nozzles, so as to wash the inner wall of the tower body, which is convenient for cleaning the inner wall of the tower body. At the same time, the ultrasonic generator and the transducer are started to drive the scraper to vibrate rapidly, so as to scrape off the dirt and solid impurities on the inner wall of the tower body. The scraping effect is improved through rapid vibration. When the motor is started, the screw rod is driven to rotate, so as to drive the installation ring to move at a uniform speed on the outer wall of the screw rod and the slide rod, so as to wash and clean the inner wall of the tower body as a whole, thereby increasing the cleaning range, saving time and effort in operation, and improving the cleaning efficiency.

The scraper has an arc structure, and the entire inner wall of the tower body can be cleaned by adjusting the angle. Compared with the ring structure, it has strong versatility and avoids the problem of jamming and damage to the scraper. BRIEF DESCRIPTION OF THE DRAWINGS
