On the contrary, the following description provides a convenient illustration of an exemplary embodiment for implementing the present disclosure. In fact, it will be clear to those skilled in the art that various modifications and variations can be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure. For example, a feature shown or described as a part of an embodiment can be used in conjunction with another embodiment to produce yet another embodiment. It is expected that the present disclosure covers such modifications and variations within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present disclosure are disclosed in or clear from the following detailed description. It will be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the wider aspects of the present disclosure.
[0021] like Figure 1-Figure 3 The figure shows a dust collector air inlet air cooling box device provided by the utility model, comprising a box body 1, an air inlet 2 and an air outlet 3 on the box body 1, the air outlet 3 is provided with a sealing connection component connected with the inlet of the dust collector, and a cooling component for cooling and pre-treating the intake air is provided on the flow path between the air inlet 2 and the air outlet 3 in the box body 1.
[0022] In a specific embodiment, the cooling assembly of the utility model includes a cooling air duct 4, which is arranged in a direction perpendicular to the gas flow path in the box body 1, and both ends of the cooling air duct 4 pass through the side wall of the box body 1 to communicate with the external atmosphere; the sealing connection assembly includes a connecting flange 6 and an expansion joint 7, the expansion joint 7 connects the air outlet 3 and the connecting flange 6, and the connecting flange 6 is connected to the dust collector inlet.
[0023] The cooling air ducts 4 of the utility model are evenly spaced and distributed in the box body 1, which can ensure uniform cooling of the intake air, and the cooling air ducts 4 can be used to evenly distribute the intake air, which is convenient for subsequent dust removal by the dust collector. The outer surface of the cooling air duct 4 is provided with anti-wear angle steel 5 in the direction of the air intake, and the corner of the anti-wear angle steel 5 is toward the side where the air inlet 2 is located. For large particles of dust or impurities contained in the intake air, the use of the anti-wear angle steel 5 can reduce the impact on the cooling air duct 4 and extend the service life of the equipment.
[0024] In order to conveniently detect the intake air cooling condition, a temperature measuring interface 8 and a pressure difference interface 9 are provided on the box body 1 of the utility model. After installing the corresponding temperature sensor and pressure difference sensor, the gas temperature and pressure difference in the air cooling box can be detected.
[0025] When the air cooling box of the utility model is in use, the flue gas enters the box body 1 from the air inlet 2, and the flue gas passes through and shuttles around the outside of the cooling air duct 4. The air inside the cooling air duct circulates and exchanges heat with the external high-temperature flue gas, thereby achieving the effect of lowering the flue gas temperature. Larger particles in the flue gas are blocked by the anti-wear angle steels of the air duct parts 3 and 8, which has a primary dust removal effect and effectively reduces the wear of the dust collector; the expansion joint 7 can effectively absorb heat expansion and protect the shell from deformation.
