Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, and specifically relates to a tail gas treatment device for skid-mounted equipment. Background Art

[0002] Skid-mounted equipment, as an efficient high-power mechanical operation tool, is widely used in various industrial sites, such as construction, mineral mining, petrochemical and other industries. While performing their functions, these devices inevitably generate a large amount of tail gas containing harmful substances, such as sulfur dioxide (SO2), nitrogen oxides (NOx) and other volatile organic compounds (VOCs). In order to meet the increasingly strict environmental protection standards and reduce the impact on the environment, the use of tail gas treatment devices becomes crucial.

[0003] Existing tail gas treatment technologies usually adopt a multi-stage purification process, including filtration, adsorption, washing and other links to remove pollutants in the tail gas. For example, Chinese Patent Application CN202320131230.6 discloses a tail gas treatment device, the design of which includes components such as a filter cartridge, an adsorption cartridge, a washing tank and a draft fan, and realizes tail gas purification through physical filtration, chemical adsorption and combustion. However, such devices have obvious volume problems, resulting in challenges in their practical applications, especially in space-constrained environments, such as being installed on skid-mounted equipment.

[0004] Due to the special structure of skid-mounted equipment, its chassis is often designed to be relatively low for easy movement in complex terrains. When a large tail gas treatment device is installed at the end of the tail gas pipe or outside the equipment, it is easy to collide with the ground or other low obstacles, resulting in damage to the device or detachment from the tail gas pipe, thus affecting the stability and safety of the tail gas treatment system.

[0005] In view of the above problems, there is an urgent need to innovate the design on the basis of the original structure of the tail gas treatment device suitable for skid-mounted equipment. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a tail gas treatment device for skid-mounted equipment, so as to solve the technical problem that when the tail gas treatment device in the prior art has a large volume and is installed at the end of the tail gas pipe or outside the equipment, it is easy to collide with the ground or other low obstacles, resulting in damage to the device or detachment from the tail gas pipe.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A tail gas treatment device for skid-mounted equipment, installed on the tail gas pipe for tail gas treatment, includes:

[0008] An exhaust pipe, the exhaust pipe is inserted into the interior of the tail gas pipe;

[0009] A snare, which is fixedly connected to the exhaust pipe and used to clamp the end of the tail pipe to fix the exhaust pipe;

[0010] An installation component, which is used to limit and install the exhaust pipe inside the tail pipe;

[0011] A filtering component, which is located inside the exhaust pipe and used to filter the tail gas.

[0012] Furthermore, the installation component includes an inclined mouth push rod, a limiting plate and a clamping post;

[0013] A through groove for accommodating the inclined mouth push rod is opened on the inner side of the exhaust pipe;

[0014] The inclined mouth push rod is slidably clamped in the through groove, and the tail end of the inclined mouth push rod is fixedly connected to the limiting plate;

[0015] The limiting plate is used to limit the sliding of the exhaust pipe when the exhaust pipe is inserted into the tail pipe;

[0016] The clamping post is used to be inserted into the exhaust pipe to squeeze the inclined mouth push rod to drive the limiting plate to tightly press against the inner wall of the tail pipe.

[0017] Furthermore, the limiting plate has an arc-shaped structure to adapt to the inner contour of the tail pipe.

[0018] Furthermore, the installation component also includes

[0019] A threaded connection ring, which is fixedly connected to one end of the snare;

[0020] A threaded sleeve, which is fixedly connected to the clamping post. By rotating the threaded sleeve, the relative position between it and the threaded connection ring is adjusted, so as to fix the exhaust pipe;

[0021] The clamping post is a through structure that communicates with the exhaust pipe to guide the discharge of flue gas.

[0022] Furthermore, patterns for increasing friction are provided on the outer side of the threaded sleeve.

[0023] Furthermore, the installation component also includes an exhaust filter screen, which is installed inside the threaded sleeve to filter the flue gas.

[0024] Furthermore, the filtering component includes an intake pipe, which is fixedly connected to the end of the exhaust pipe away from the snare and forms a through structure with the exhaust pipe to guide the tail gas into the treatment device.

[0025] Furthermore, the filtering component includes

[0026] Filter plates, which are used to adsorb large particle pollutants in the tail gas;

[0027] Graphite adsorption plate, used for adsorbing harmful gases in the tail gas;

[0028] Activated carbon filter screen, further removing other harmful components in the tail gas.

[0029] Furthermore, the filter plate, graphite adsorption plate and activated carbon filter screen are arranged in sequence from bottom to top inside the exhaust pipe.

[0030] Compared with the prior art, the beneficial effects of the present utility model are that the tail gas treatment device suitable for skid-mounted equipment is provided with:

[0031] 1. By designing the exhaust pipe to penetrate through the tail gas pipe, the overall volume is reduced, and a filtering component is arranged inside the exhaust pipe to optimize the space utilization, thereby solving the problems in the prior art that when the tail gas treatment device is large in size and installed at the end of the tail gas pipe or outside the equipment, it is easy to collide with the ground or other low obstacles, resulting in damage to the device or detachment from the tail gas pipe, and using the installation component to ensure the stability and safety of the tail gas treatment device.

[0032] 2. A structure that is easy to install. When installing the tail gas treatment equipment, first insert the exhaust pipe into the inner side of the tail gas pipe until the sleeve is clamped at the tail of the tail gas pipe. Then insert the clamping column into the inner side of the exhaust pipe and rotate the threaded sleeve to make the threaded sleeve threadedly connected with the threaded connection ring. As the threaded sleeve is continuously rotated, the threaded sleeve will move continuously towards the exhaust pipe along the texture on the outer side of the threaded connection ring, so that the clamping column inside the threaded sleeve will move accordingly and continuously squeeze the inclined mouth push rod on the outside. After being squeezed, the inclined mouth push rod will slide along the inner side of the through groove, so that the limiting plate at the tail end of the inclined mouth push rod closely fits on the inner side of the tail gas pipe. Through the cooperation of multiple groups of limiting plates, the exhaust pipe is fixed inside the tail gas pipe to treat the tail gas inside the tail gas pipe. This structure not only achieves the effect of being easy to install, but also installs the tail gas treatment equipment inside the tail gas pipe, thereby reducing the risk of the tail gas treatment equipment being collided.

[0033] 3. A filtering structure. This structure installs a filter plate, a graphite adsorption plate and an activated carbon filter screen inside the exhaust pipe. The filter plate can capture the particulate matter in the tail gas. The graphite adsorption plate utilizes the characteristics of graphite materials to adsorb and remove the harmful substances in the tail gas. The activated carbon filter screen, relying on its huge specific surface area and rich pore structure, can effectively adsorb the harmful substances in the tail gas. Through the above structure, the harmful substances in the tail gas are effectively removed, making the tail gas emission cleaner and more environmentally friendly. Description of the Drawings
