Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, and particularly relates to an odor filtering structure for desulfurizing coal-fired flue gas. Background Art

[0002] The coal-fired flue gas emissions from the power, chemical, metallurgical, and manufacturing industries have a great impact on air pollution. Among them, the harmful substances such as soot, sulfur dioxide, and nitrogen oxides contained in the coal-fired flue gas are one of the roots of air pollution, acid rain, and the greenhouse effect.

[0003] In current flue gas desulfurization, the particulate matter in the flue gas basically directly contacts the filter net, which will greatly increase the load on the filter net, thereby reducing the service life of the filter net and requiring frequent replacement, resulting in the difficulty for the desulfurization mechanism to be put into use for a long time. Content of the Utility Model

[0004] Therefore, the utility model provides an odor filtering structure for desulfurizing coal-fired flue gas to solve the above problems in the prior art.

[0008] A blocking plate is installed inside the installation pipe, a hole structure is formed in the middle of the blocking plate, a plurality of limiting pipes are uniformly arranged on the lower side of the blocking plate, and through hole structures corresponding to the limiting pipes one by one are formed inside the blocking plate;

[0009] A filtering mechanism is installed on the upper side of the blocking plate for filtering.

[0010] Further, a guiding ring is installed at the upper end of the installation pipe, and the inner side of the guiding ring is inclined.

[0011] Further, the filtering mechanism includes a filter net, and a reinforcing ring is installed on the outer side of the filter net.

[0023] The following specific embodiments illustrate the implementation manners of the utility model. Those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in this specification. Obviously, the described embodiments are some embodiments of the utility model, rather than all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.

[0024] As shown Figures 1 to 4 in the figure, an odor filtering structure for desulfurization of coal-fired flue gas in the first aspect embodiment of the present utility model includes an installation pipe 1. A guiding seat 2 is installed inside the lower end of the installation pipe 1. The outer side of the guiding seat 2 is inclined, and the inner opening of the guiding seat 2 is inclined. A collecting groove 4 is installed on the outer side of the guiding seat 2. A positioning ring 3 is fixed to the outer end inside the collecting groove 4, so that the collecting groove 4 and the positioning ring 3 can carry the particulate matter in the coal-fired flue gas;

[0025] A blocking plate 5 is installed inside the installation pipe 1. A hole structure is provided in the middle of the blocking plate 5. Limiting pipes 6 are uniformly arranged on the lower side of the blocking plate 5, and through hole structures corresponding to the limiting pipes 6 one by one are provided inside the blocking plate 5;

[0026] A filtering mechanism 7 is installed on the upper side of the blocking plate 5 for filtering;

[0027] Specifically, during the process of the flue gas being discharged into the installation pipe 1, due to the inner opening of the guiding seat 2 being inclined, the flue gas shows a state of spreading outwards when entering the installation pipe 1. After the flue gas enters the installation pipe 1, some flue gas particles fall downward due to their own weight, while a part of the flue gas continues to move upward. The part of the flue gas that spreads outwards is blocked by the blocking plate 5, and the flue gas can only be discharged from the hole structure in the middle of the blocking plate 5. Thus, it is filtered by the filtering mechanism 7, and some of the filtered particulate matter is guided downward by the blocking plate 5 and discharged from the through hole structures provided in the blocking plate 5, thereby preventing the particulate matter from staying in the filtering mechanism 7 and reducing the possibility of blockage. The fallen particulate matter falls into the collecting groove 4 for centralized collection, thereby reducing the filtering load of the particulate matter on the filtering mechanism 7 and preventing the particulate matter from continuously generating a filtering demand on the filtering mechanism 7.

[0028] A guiding ring 10 is installed at the upper end of the installation pipe 1. The inner side of the guiding ring 10 is inclined, which can gather the discharged flue gas inwards and increase the wind pressure during discharge.

[0029] The filtering mechanism 7 includes a filter net 701. A reinforcing ring 702 is installed on the outer side of the filter net 701 to increase the strength on the outer side of the filter net 701;

[0030] A limiting mechanism 8 is further installed on the outer side of the reinforcing ring 702 for controlling the gap between the single bodies of the reinforcing ring 702, preventing contact between the reinforcing rings 702, thereby being able to prevent contact between the filter nets 701 and avoiding the change of the filtration mesh number of the contact surface after contact between the single bodies of the filter nets 701.

[0031] The limiting mechanism 8 includes a mounting ring 801. A limiting rod 802 is fixed to the inner side of the mounting ring 801, and a spring structure is arranged on the outer side of the limiting rod 802. One end of the spring is connected to a blocking ring 803. The inner diameter of the blocking ring 803 is smaller than the inner diameter of the reinforcing ring 702, which is convenient for supporting the reinforcing ring 702.

[0032] A limiting bolt 9 is also elastically connected to the inner side of the positioning ring 3 for limiting the installation between the positioning ring 3 and the installation pipe 1.

[0033] The surface of the limiting bolt 9 is inclined, which is convenient for connecting between the positioning ring 3 and the installation pipe 1 and also convenient for removing the positioning ring 3.
