Description

Technical Field

[0001] This application relates to the technical field of exhaust gas treatment devices, and specifically discloses an exhaust gas treatment device for chili granulation. Background Technology

[0002] During the granulation process of chili peppers, the exhaust fumes contain irritating odors that can cause discomfort to the eyes, nose, and throat. Long-term exposure to these fumes can cause respiratory problems such as coughing, wheezing, and difficulty breathing, posing a potential risk to human health. The exhaust fumes also have negative environmental impacts, such as air pollution and odor diffusion; therefore, a process to remove the spiciness from the chili pepper granulation exhaust fumes is necessary.

[0003] Currently, the main methods for treating exhaust gas from chili granulation include waste gas scrubbing, heat recovery, spray tower treatment, UV photodeodorization, and activated carbon adsorption. After passing through the feeding, crushing, and granulation stages, chilies are formed into granules. The powder generated during granulation is recovered and granulated. The exhaust gas generated during chili granulation enters the deodorization stage through exhaust gas treatment pipes. However, in existing technologies, most devices installed in the deodorization stage only have deodorization functions and cannot simultaneously handle dust removal and deodorization.

[0004] Therefore, the inventors have provided a chili granulation exhaust gas treatment device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that most of the devices installed in traditional deodorization sections only have deodorization functions and cannot simultaneously address the issues of dust removal and deodorization.

[0006] To achieve the above objectives, the basic solution of this utility model provides a chili granulation exhaust gas treatment device, including a pulse filter cartridge dust collector connected to the exhaust gas treatment pipeline, a spray purification tower connected to the top of the pulse filter cartridge dust collector, an exhaust fan connected to the top of the spray purification tower, and an exhaust duct connected to the exhaust fan. The bottom of the pulse filter cartridge dust collector is also connected to a chili dust collection pipeline.

[0007] Furthermore, it also includes a filter press, and a filter press depressor pipe is connected between the bottom of the spray purification tower and the filter press for supplying absorbent liquid to the filter press.

[0008] Furthermore, a liquid supply pipe is connected between the filter press and the spray purification tower for supplying the absorbent liquid after filter pressing to the spray purification tower, and the liquid supply pipe is equipped with a water pump.

[0009] Furthermore, the spray purification tower is equipped with a spray mechanism, which is connected to the liquid supply pipeline.

[0010] Furthermore, the pulse cartridge dust collector includes a primary pulse cartridge dust collector and a secondary pulse cartridge dust collector connected sequentially between the exhaust gas treatment pipeline and the spray purification tower. The bottom of both the primary and secondary pulse cartridge dust collectors is connected to a chili powder collection pipeline.

[0011] Furthermore, the spray purification tower includes a primary spray purification tower and a secondary spray purification tower connected sequentially between the pulse cartridge dust collector and the exhaust fan.

[0012] The principle and effect of this solution are as follows:

[0013] Compared with existing technologies, this utility model uses a pulse filter cartridge dust collector to filter dust through a dry dust removal process, separating the dust in the chili granulation exhaust gas from the clean air. Then, a wet deodorization process is used through a spray purification tower. By introducing the chili granulation exhaust gas that has undergone dry dust removal into an absorbent liquid, the remaining impurities and spiciness are absorbed, thus completing the treatment of the chili granulation exhaust gas. It has both dust removal and deodorization functions, solving the problem that most of the devices installed in traditional deodorization sections only have deodorization functions and cannot simultaneously handle dust removal and deodorization.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 A schematic diagram of a chili granulation tail gas treatment device according to an embodiment of this application is shown. Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] The reference numerals in the accompanying drawings include: exhaust gas treatment pipeline 1, primary pulse cartridge dust collector 2, secondary pulse cartridge dust collector 3, filter press 4, first spray purification tower 5, second spray purification tower 6, exhaust fan 7, exhaust duct 8, chili dust collection pipeline 9, filter press pipeline 10, liquid supply pipeline 11.

[0018] A chili granulation exhaust gas treatment device, implementing, for example Figure 1 As shown:

[0019] It includes a pulse jet filter cartridge dust collector connected to the exhaust gas treatment pipeline 1, a spray purification tower connected to the top of the pulse jet filter cartridge dust collector, an exhaust fan 7 connected to the top of the spray purification tower, and an exhaust duct 8 connected to the exhaust fan 7.

[0020] Specifically, in this embodiment, the pulse jet cartridge dust collector includes a primary pulse jet cartridge dust collector 2 and a secondary pulse jet cartridge dust collector 3 connected in sequence. The exhaust gas treatment pipeline 1 is connected to the primary pulse jet cartridge dust collector 2, and the secondary pulse jet cartridge dust collector 3 is connected to the spray purification tower. Chili powder collection pipelines 9 are respectively connected to the bottom of the primary pulse jet cartridge dust collector 2 and the secondary pulse jet cartridge dust collector 3.

[0021] The spray purification tower includes a primary spray purification tower and a secondary spray purification tower connected in sequence. The primary spray purification tower is connected to the secondary pulse filter cartridge dust collector 3, and the secondary spray purification tower is connected to the exhaust fan 7.

[0022] In this embodiment, a set of filter presses 4 are also installed. The bottom of the primary spray purification tower and the bottom of the secondary spray purification tower are connected to the filter presses 4 by a filter-to-press pipe 10 for supplying absorbent liquid to the filter presses 4. A liquid supply pipe 11 for supplying the filtered liquid after pressing into the tower body is also connected between the filter presses 4 and the primary spray purification tower and the secondary purification tower. The liquid supply pipe 11 is equipped with a water pump.

[0023] Furthermore, spraying mechanisms are installed inside both the primary and secondary spray purification towers, and the liquid supply pipes 11 are connected to the liquid supply pipes 11.

[0024] In this embodiment, both the primary pulse cartridge dust collector 2 and the secondary pulse cartridge dust collector 3 are pulse cartridge dust collectors, which are dry dust removal methods used to separate chili powder dust from clean air. Furthermore, both the primary and secondary spray purification towers have a packing layer below the spray mechanism and a demister plate above the spray mechanism.

[0025] When this utility model is used, the dust is filtered by the primary pulse cartridge dust collector 2 and the secondary pulse cartridge dust collector 3 through a dry dust removal process, separating the dust in the chili granulation tail gas from the clean air, and the separated dust is discharged through the chili dust collection pipe 9.

[0026] The exhaust gas from the secondary pulse filter cartridge dust collector 3 enters the primary spray purification tower. The primary and secondary spray purification towers use a wet deodorization process to rotate and rise the chili granulation tail gas through the packing layer, where it fully contacts and absorbs the downward sprayed absorbent liquid. Then, it passes through the demister plate and is discharged by the exhaust fan 7 through the top of the exhaust duct 8, with a discharge height of not less than 15 meters.

[0027] Furthermore, in the primary and secondary spray purification towers, the absorbent is returned to the bottom of the tower and introduced into the filter press 4. After the filter press 4 removes the remaining impurities to obtain the chili filter cake, the resulting filtrate is pumped back into the spray mechanism for reuse. Simultaneously, the absorbent uses an industrial alkaline solution and maintains a certain concentration to prevent uneven treatment or leakage of waste gas due to variations in the absorbent.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
