Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

As shown in figure 1, a gaseous defogging purifier, including casing (4), air inlet (5) of setting in casing (4) below, and one-level defogging module (7) of air inlet (5) intercommunication, support piece (8) and second grade defogging module (9) that are located one-level defogging module (7) top, flower disc (11) of setting in casing (4) top, filter element (10) of fixing on flower disc (11) and gas outlet (12) that are located casing (4) top.

The device also comprises a lower sealing head (3) arranged at the bottom of the shell (4), a liquid discharge port (14) is arranged at the bottom of the lower sealing head (3), and a vortex-proof port (2) is arranged on the liquid discharge port (14).

The bottom of the shell (4) is provided with a base (1) which is convenient for fixing the shell (4).

The primary demisting module (7) is of a tubular structure, and a groove (71) is formed in the lower portion of the tubular structure. And a primary filter (6) is arranged in the primary demisting module (7) and close to one side of the air inlet (5).

The secondary demisting module (9) is detachably arranged on the support piece (8), the secondary demisting module (9) is a wire mesh demister, and the wire mesh demister is provided with an electric heating structure.

The device further comprises a manhole (13) arranged in the side wall above the housing (4), said manhole (13) being located below the filter element (10). Because this kind of device is used in industrial waste gas treatment more, and the handling capacity is great, therefore casing (4) can be designed into very big structure usually, when needing to be changed filtering element (10) so, in the staff only need get into the device through manhole (13), change filtering element (10) can, need not spend more manpower, material resources and open the top cap of casing (4) and change filtering element (10), it is more convenient to operate.

The filter element (10) is a bag filter element or a core filter element, the core filter element is a metal filter element or a ceramic filter element, and the upper surface of the metal filter element or the ceramic filter element is coated with a catalyst. In this embodiment, a ceramic filter element having a catalyst supported on the surface thereof is preferred.

The working principle is as follows: industrial waste gas enters the shell (4) through the air inlet (5), is pre-filtered through the primary filter (6), and intercepts larger particles in the gas, so that the large particles are prevented from falling into the liquid outlet (14) to block liquid discharge when impacting the primary demisting module (7). When waste gas passes through one-level defogging module (7), most steam is intercepted and drips to low head (3) storage in the gas, when low head (3) liquid is too much, opens leakage fluid dram (14) flowing back, and the design of preventing vortex mouth (2) can prevent effectively that the water vortex from forming, and the flowing back is more unobstructed.

The gas after the preliminary defogging drying of one-level defogging module (7) upwards flows, carries out electrical heating drying process through second grade defogging module (9), and the silk screen demister is preferred to this embodiment. The gas is demisted and dried and then flows to the filter element (10) for dust removal.

When the waste gas is required to be subjected to desulfurization, denitration and other treatments, a metal filter element or a ceramic filter element with a catalyst loaded on the surface can be selected, and at the moment, the gas has higher temperature, so that the catalytic desulfurization and denitration treatment can be carried out when the dust is removed by the filter element (10), and finally the clean gas is discharged through the gas outlet (12).

Of course, if the water vapor in the waste gas is less or the desulfurization and denitration treatment is not needed, the wire mesh demister can not be heated, and the filter element (10) can also be purified and dedusted at a lower temperature by using a common bag filter.

The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
