Description

Technical Field

[0001] The utility model relates to the technical field of RTO waste gas filtering, in particular to an RTO waste gas filtering device. Background Art

[0002] RTO is a highly efficient organic waste gas treatment equipment. Compared with traditional catalytic combustion and direct-fired thermal oxidation furnaces, it has the characteristics of high thermal efficiency, low operating cost, and the ability to treat a large amount of low-concentration waste gas. Its principle is to oxidize the organic matter in the waste gas into corresponding carbon dioxide and water at high temperature, thereby purifying the waste gas and recovering the heat released when the waste gas decomposes.

[0003] However, the discharged organic waste gas contains various impurities and needs to be filtered. However, the filter of the current filtering device is easily clogged, affecting the airflow, thereby reducing the working efficiency of the filtering device. In addition, the filtering device needs to be shut down when replacing the filter, affecting the continuity of work. Therefore, we proposed an RTO waste gas filtering device. Utility Model Content

[0006] Taking the first filter plate in the filter box as an example, the organic waste gas enters from the air inlet, is filtered by the first filter plate and then discharged from the exhaust port. The wind pressure detection device detects the wind pressure of the air inlet and the exhaust port. When the wind pressure of the exhaust port is less than the set value, it means that the impurities on the first filter plate have accumulated to a certain amount. At this time, the second cylinder drives the second filter plate to slide into the filter box to replace the first filter plate for filtering. The first cylinder then drives the first filter plate to slide into the cleaning box. The spray head sprays the detergent in the water tank onto the first filter plate for cleaning. After cleaning, the fan is used to blow dry the first filter plate, thereby achieving the purpose of continuous operation of the filter device and avoiding clogging of the filter plate.

[0007] Preferably, the first chute and the second chute are both surrounded by two first fixed frames and the inner side wall of the filter box, and the third chute and the fourth chute are both surrounded by two second fixed frames and the inner side wall of the cleaning box.

[0008] Preferably, the sizes of the first chute and the third chute are the same as the size of the first filter plate, and the sizes of the second chute and the fourth chute are the same as the size of the second filter plate. The first filter plate is closely fitted with the first chute and the third chute, and the second filter plate is closely fitted with the second chute and the fourth chute, respectively, to increase the sealing between the filter plate and the chute.

[0009] Preferably, the first filter plate and the second filter plate are both detachably mounted with multiple layers of filter screens. The filter screens and the filter plates are detachably mounted, and if the filter screens need to be replaced, only the filter screens need to be removed without replacing the filter plates.

[0010] Preferably, the push rod of the first cylinder passes through the cleaning box and is fixedly connected to the side of the first filter plate, and the push rod of the second cylinder passes through the cleaning box and is fixedly connected to the side of the second filter plate. The first cylinder can drive the first filter plate to slide, and the second cylinder can drive the second filter plate to slide.

[0011] Preferably, a collecting box is movably installed at the bottom of the cleaning box. The collecting box can collect impurities and detergent on the filter screen.

[0012] Preferably, a door panel is provided on the side wall of the cleaning box, so that the staff can take out the collection box and inspect the filter plate by opening the door panel.

[0013] Preferably, the wind pressure detection device is electrically connected to the first cylinder and the second cylinder. The wind pressure detection device presets a detection value, and if the detected wind pressure is less than the preset value, the first cylinder and the second cylinder are automatically controlled to work and exchange the filter plates.

[0014] Preferably, the first chute is connected to the third chute, and the second chute is connected to the fourth chute, so that the first filter plate and the second filter plate can move back and forth between the filter box and the cleaning box.

[0015] Compared with the prior art, the utility model adopts the above technical solution and has the following technical effects:

[0016] The utility model provides a cleaning box, a first filter plate and a second filter plate. The two filter plates are slidably connected to the cleaning box and the filter box, so that the two filter plates can slide into the filter box alternately for filtering. When one filter plate is filtering, the other filter plate is cleaned in the cleaning box, thereby achieving the purpose of continuous operation of the filter device. At the same time, the cleaning box is used to solve the problem of blockage caused by too many impurities on the filter plate, thereby effectively improving the working efficiency of the filter device.
