Tail gas dedusting and purifying device

Abstract

The invention relates to a tail gas dedusting and purifying device. The tail gas debusting and purifying device comprises a connecting component and a purifying device body. The connecting component comprises a connecting pipe, a sealing ring, a connecting sleeve and an adjusting bolt. The purifying device body comprises a shell, a high-voltage electrostatic dedusting component, a first filteringcomponent and a second filtering component. The high-voltage electrostatic dedusting component comprises a high-voltage power supply, an anode plate and a cathode plate. According to the tail gas dedusting and purifying device, the adjusting bolt is in threaded connection with the connecting sleeve; firstly, an external tail gas pipe is sleeved with the connecting sleeve, and then the adjusting bolt is screwed to fasten the connecting sleeve, so that the sealing and fastening degree of the connection of the external tail gas pipe and the connecting sleeve is higher; and the high-voltage electrostatic dedusting assembly, the first filtering component and the second filtering component are all fixedly connected with the shell, the tail gas is filtered and purified in multiple ways, and the high-voltage electrostatic dedusting assembly comprises the high-voltage power supply, the anode plate and the cathode plate, and the tail gas dedusting and purifying device has the beneficial effectsof low energy consumption, high dedusting efficiency and the like in electrostatic dedusting.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to a dust removal and purification device for tail gas. Background technique [0002] With the rapid development of the automobile and ship industry, gasoline engines and diesel engines are used more and more widely, so the exhaust gas produced by gasoline engines and diesel engines is also increasing, and the most common treatment methods at present can no longer meet the requirements of environmental protection , the increasingly standardized environmental protection standards have also improved the national awareness of environmental protection, but the existing exhaust gas treatment devices are easy to block the exhaust holes, making the engine's work efficiency low, catalytic conversion efficiency low, and energy consumption.

[0002] With the rapid development of the automobile and ship industry, gasoline engines and diesel engines are used more and more widely, so the exhaust gas produced by gasoline engines and diesel engines is also increasing, and the most common treatment methods at present can no longer meet the requirements of environmental protection , the increasingly standardized environmental protection standards have also improved the national awareness of environmental protection, but the existing exhaust gas treatment devices are easy to block the exhaust holes, making the engine's work efficiency low, catalytic conversion efficiency low, and energy consumption. A more effective tail gas treatment device, such as a Chinese invention patent (publication number: CN205714359U), discloses a special automatic dust removal and purification device for automobile exhaust purification, including a heat-insulating host shell (2), a filter screen (13), a dust discharge hole ( 14) and an ignition device (17), characterized in that: an air inlet (16) is provided on the left side of the heat preservation main engine shell (2), and a sealing device (1) is arranged on the air inlet (16), and the A fuel tank (5) is arranged on the top of the heat preservation main engine shell (2), an air-fuel mixing injection device (6) is arranged on the right side of the fuel tank (5), and a Hydraulic expansion device (4), the bottom of described hydraulic expansion device (4) is provided with automatic dedusting brush head (3), and described filter screen (13) is installed on the both sides of automatic dust removal brush head (3), and filter screen The left side of (13) is provided with gas component detecting device (15), and described ignition device (17) is installed on the inner upper part of heat preservation host shell (2), and the interior right side of described heat preservation host shell (2) is provided with catalytic A conversion device (11), the left side of the catalytic conversion device (11) is provided with a temperature detection device (7), and the two ends of the temperature detection device (7) are provided with a high temperature resistant fixing device (12), the heat preservation host The right side of the housing (2) is provided with an exhaust fan (9), the right side of the exhaust fan (9) is provided with an exhaust port (10), and the lower part of the heat preservation host housing (2) is provided with a fixing device (8), the dust discharge hole (14) is installed under the heat preservation host shell (2), the air-fuel mixing injection device (6), temperature detection device (7), exhaust fan (9), gas composition Both the detection device (15) and the ignition device (17) are electrically connected to the external control panel. The automatic dust removal and purification device for automobile exhaust gas purification has a scientific and reasonable structure, and is safe and convenient to use. The sealing device can prevent exhaust gas from leaking and improve purification efficiency. , the heat preservation of the host shell can effectively prevent temperature loss, the automatic dust removal brush head can effectively remove the dust on the filter net, the exhaust fan is convenient to speed up the exhaust speed, and at the same time reduce the probability of engine blockage, the temperature detection device can detect the internal temperature of the device in real time, The air-fuel mixing injection device can automatically adjust the mixing ratio of air and fuel. However, when the purification device is connected to the exhaust pipe, the fixing device is rigidly fixed. The purification device moves with the car during use, which is prone to loosening and cannot be carried out. Adjustment makes the stability of the purification device poor, and the purification device only passes through the general filter, the filtering effect is poor, and the dust removal effect is poor , and the dust in the purification device is directly discharged outside the purification device, which brings inconvenience to use, and the purification device is connected to the outside through a fixing device, and the disassembly and installation process are relatively cumbersome
