Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to mixed waste gas treatment equipment. Background Art

[0002] Coal yards and other places generate a large amount of waste gas during daily production, and the waste gas contains harmful substances of different natures. Therefore, multiple sets of purification equipment are currently used to purify the mixed waste gas, such as desulfurization towers, purifiers, and waste gas treatment boxes connected by pipes.

[0003] The interior of the exhaust gas treatment box is divided into multiple cavities, and purification devices for purifying the exhaust gas are arranged in the cavities. A baffle door is arranged on one side of each of the multiple cavities to facilitate the cleaning of the purification devices inside the cavities at a later time. However, after the exhaust gas enters the exhaust gas treatment box, exhaust gas leakage is prone to occur, and in the process of cleaning the purification devices inside the exhaust gas treatment box, impurities in different cavities are prone to cross-movement.

[0004] The main reason for the above problems is that the multiple cavities inside the exhaust gas treatment box are in a connecting device, and there is no device for separating the multiple cavities. When cleaning the purification device, it is necessary to open the baffle door first. After a set of baffle doors are opened, the multiple cavities inside the exhaust gas treatment box are connected to the external environment. At this time, under the influence of the external environment airflow, the impurities or exhaust gas accumulated in the multiple cavities move around inside the exhaust gas treatment box, resulting in scattered impurities inside the exhaust gas treatment box, making it inconvenient to clean the impurities conveniently. In addition, when the baffle door is closed, the degree of sealing between it and the cavity is not high, which makes it easy for some exhaust gas to flow into the external environment through the gap between the baffle door and the inner wall of the cavity, causing pollution to the external environment. To address the above problems, we propose a mixed exhaust gas treatment device. Utility Model Content

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a mixed exhaust gas treatment device, including an exhaust gas treatment box and a cavity opened inside the exhaust gas treatment box, one side of the cavity is rotatably connected to a baffle, and the inner wall of the cavity close to the baffle is provided with a sealing mechanism, and the sealing mechanism includes:

The model of the exhaust gas treatment box 1 is BS-LZ36K. When purifying the mixed exhaust gas, the mixed exhaust gas is first transported to the inside of the desulfurization tower 4 through a conveying pipe, and then under the action of the fan 6, the mixed exhaust gas passes through the connecting pipe 8 in turn into the inside of the purifier 5 and the exhaust gas treatment box 1, so that exhaust gases of different properties are purified by different purification equipment, and the clean gas after purification can be directly discharged into the external environment through the exhaust pipe 7.

[0030] After the exhaust gas enters the exhaust gas treatment box 1, the filter components such as the filter plate 2 inside the exhaust gas treatment box 1 will purify the exhaust gas.

[0031] The inner wall of the cavity 101 near the baffle 102 is provided with a sealing mechanism, that is, when the baffle 102 is closed, the sealing mechanism blocks and seals the baffle 102 and the cavity 101 to prevent the exhaust gas from flowing directly into the external environment through the door gap. For details, please refer to the attached Figure 2 After the baffle door 102 is opened, the sealing mechanism blocks and seals the two adjacent cavities 101 in the exhaust gas treatment box 1 to prevent the exhaust gas and impurities accumulated in different cavities 101 from mixing when the filter plate 2 in one cavity 101 is cleaned. For details, please refer to the attached Figure 3 The sealing mechanism includes an L-shaped guide rail 301, which is arranged at the inner bottom of the cavity 101. The sealing plate 302 is slidably connected to the L-shaped guide rail 301. The bottom end surface of the sealing plate 302 contacts the top end surface of the L-shaped guide rail 301.

[0033] The mixed exhaust gas treatment equipment, by respectively arranging a group of combined L-shaped guide rails 301 and sealing plates 302 in multiple groups of cavities 101 of the exhaust gas treatment box 1, enables the sealing mechanism to prevent the exhaust gas from flowing directly into the external environment through the door gap when the baffle door 102 is closed, and after the baffle door 102 is opened, the sealing mechanism can prevent the exhaust gas and impurities accumulated in different cavities 101 from moving randomly inside the exhaust gas treatment box 1 when the filter plates 2 inside a group of cavities 101 are cleaned, making it inconvenient to clean the interior of the exhaust gas treatment box 1 later.
