Description

Technical Field

[0001] This utility model belongs to the technical field of waste gas treatment equipment, specifically relating to a chemical waste gas filter barrel. Background Technology

[0002] In chemical production processes, waste gas is an unavoidable byproduct, mainly originating from raw material handling, reaction processes, product refining, equipment leaks, and storage and transportation. Chemical waste gas is complex and diverse, including but not limited to volatile organic compounds (VOCs), sulfides, nitrogen oxides, particulate matter (PM), acidic gases (such as sulfur dioxide and chlorine), and malodorous gases. These waste gases are not only irritating and corrosive, but some are also toxic or carcinogenic, posing a serious threat to the environment and human health.

[0003] Therefore, this application provides a chemical waste gas filter barrel. This application adopts a filter cartridge structure with a double-joint cover, allowing for selective single-sided or double-sided gas collection and filtration processes via a dual-station filter element, completing the specified waste gas treatment process according to the site environment. Simultaneously, the double-layer structure of the outer shell and the recovery chamber prevents gas leakage due to valve root rupture, ensuring immediate sealing and transfer to avoid secondary pollution. Furthermore, the bottom mobile trolley can adaptively adjust its position according to terrain and site conditions, accommodating pipeline connections. Summary of the Invention

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A chemical waste gas filter barrel includes an outer shell and a cover; the openings on the left and right sides of the outer shell are fitted with caps, and a recovery chamber is installed inside the outer shell. The openings on the left and right sides of the recovery chamber are fitted with installation joints, which are connected to the cover.

[0006] A waste gas recovery valve is installed at the center of the main viewing end face of the recovery chamber. The connecting pipe of the waste gas recovery valve extends out along the mounting hole in the center of the outer shell, and the extended connecting pipe is unidirectionally connected to the external gas box.

[0007] Furthermore, a mobile trolley is connected to the bottom of the outer casing via a synchronous base;

[0008] The top plane of the mobile trolley is connected to the synchronous base;

[0009] The mobile trolley is equipped with four sets of track wheels on its front and rear ends, and tracks are mounted on the track wheels.

[0010] Furthermore, the outer casing has a movable window along the outer ring of the mounting hole, and a dustproof cover is installed on the inner ring of the movable window. The dustproof cover is connected to the mounting hole through a sealing ring.

[0011] Furthermore, two sets of limiting ribs are longitudinally installed on the inner wall of the outer shell. The limiting ribs are in limiting contact with the partition ribs, and the partition ribs are longitudinally installed at the center of the recovery cavity.

[0012] Furthermore, a filter element is installed inside the cover, and the two ends of the filter element are sealed and connected to the cover and the mounting joint respectively through sealing rings.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with existing technologies, this application adopts a filter cartridge structure with a dual-connector housing. The dual-station filter element allows for selective single-sided or double-sided gas collection and filtration, enabling the completion of specific waste gas treatment processes tailored to the site environment. Simultaneously, the double-layer structure of the outer shell and the recovery chamber prevents gas leakage due to valve root rupture, ensuring immediate sealing and transfer to avoid secondary pollution. Furthermore, the bottom-mounted mobile trolley can adaptively adjust its position according to terrain and site conditions, accommodating pipeline connections. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0020] like Figure 1 and Figure 2 As shown, a chemical waste gas filter barrel includes an outer shell and a cover. The outer shell 6 has openings on both sides with caps 1 installed. A recovery chamber 12 is installed inside the outer shell 6. The recovery chamber 12 has openings on both sides with mounting connectors 8, which connect to the cover 11. The recovery chamber 12 is housed inside the outer shell 6, and the double-chamber structure protects the internal gas from leakage, providing secondary protection. The double-connector cover 11 structure on both sides of the recovery chamber 12 allows for the completion of the waste gas filtration and collection process through a bidirectional waste gas filtration and collection structure.

[0021] A waste gas recovery valve 9 is installed at the center of the main viewing end face of the recovery chamber 12. The connecting pipe of the waste gas recovery valve 9 extends along the mounting hole 3 at the center of the outer shell 6, and the extended connecting pipe is unidirectionally connected to an external gas box. The waste gas collected in the recovery chamber 12 after preliminary filtration is then uniformly recovered to the external gas box by the waste gas recovery valve 9 for further filtration. The unidirectional connection is to prevent gas backflow, which could lead to insufficient filtration.

[0022] like Figure 1 and Figure 2 As shown, a mobile trolley is connected to the bottom of the outer shell 6 via a synchronous base 13;

[0023] The top plane of the mobile trolley is connected to the synchronous base 13;

[0024] The mobile trolley is equipped with four sets of tracked wheels 15 on its front and rear ends, and tracks 14 are mounted on the tracked wheels 15. The trolley can move the outer shell 6 and the recovery chamber 12 to a suitable location and orientation to complete the pipeline connection and waste gas recovery process through the tracked wheels 15 and tracks 14.

[0025] like Figure 1 and Figure 2 As shown, the outer casing 6 has a movable window 2 along the outer ring of the mounting hole 3. A dustproof cover 7 is installed on the inner ring of the movable window 2, and the dustproof cover 7 is connected to the mounting hole 3 through a sealing ring 4. The dustproof cover 7 can be adjusted in conjunction with the position of the mounting hole 3, thereby further adjusting the left and right position of the recovery chamber 12. During adjustment, the recovery chamber 12 can further seal one side of the cover 11 by left and right displacement, focusing on enhancing the gas recovery intensity of the other side of the cover 11. The dustproof cover 7 serves a sealing function.

[0026] like Figure 1 and Figure 2 As shown, two sets of limiting ribs 5 are longitudinally installed on the inner wall of the outer shell 6. The limiting ribs 5 are in limiting contact with the partition ribs 10, and the partition ribs 10 are longitudinally installed at the center of the recovery cavity 12. The limiting ribs 5 and the partition ribs 10 serve to limit displacement. This is a protective structure.

[0027] like Figure 1 and Figure 2 As shown, a filter element 16 is installed inside the cover 11. The two ends of the filter element 16 are sealed to the cover 11 and the mounting joint 8 respectively by sealing rings. The filter element 16 can perform a preliminary filtration process.

[0028] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
