Description

Technical Field

[0001] This utility model relates to the field of reactor exhaust gas treatment technology, and in particular to a reactor exhaust gas emission treatment device. Background Technology

[0002] In a broad sense, a reaction vessel is a container that undergoes physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. The exhaust gas emitted from reaction vessels may pollute the environment and needs to be treated. This necessitates a reaction vessel exhaust gas treatment device.

[0003] To address this, Chinese patent application CN208493671U discloses a waste gas emission treatment device connected to a production workshop. The device includes an emission pipe connected to one side of the production workshop, composed of multiple short pipe sections joined together. Each short pipe has a flange at both ends, with a positioning rod circumferentially fixed to one end of the flange. The positioning rod is perpendicular to the flange and extends outwards from the short pipe. During installation, the short pipe can be pre-aligned using the positioning rod, making the installation process relatively easy and efficient.

[0004] 1. The above-mentioned exhaust gas treatment device can be installed by aligning the short pipe in advance with the positioning rod, which makes the installation process relatively easy and efficient. However, during use, only one filtration and cleaning may result in poor treatment effect and difficulty in circulating and purifying the exhaust gas. Utility Model Content

[0005] The purpose of this invention is to provide a reactor exhaust gas treatment device to solve the problem that existing reactor exhaust gas treatment devices are difficult to recycle exhaust gas.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reaction vessel exhaust gas treatment device, including a filter box;

[0007] An inlet is installed at the top of one side of the filter box, a discharge pump is installed at the bottom of one side of the filter box, a connecting pipe is installed on one side of the discharge pump, and a cleaning box is installed on one side of the connecting pipe.

[0008] The cleaning box is equipped with a filter element inside, and an outlet is installed at the bottom of one side of the cleaning box. A circulation mechanism is installed at the top of the outlet.

[0009] The circulation mechanism includes an inlet installed at the top of the outlet, a conduit installed at the top of the inlet, a pump body installed at the bottom of the conduit, and an outlet installed at the top of the conduit.

[0010] In use, firstly, exhaust gas is fed into the filter box through the inlet. The filter screen filters the exhaust gas and removes dust. After filtration by the filter screen inside the filter box, the discharge pump operates and drives the filtered exhaust gas into the cleaning box through the connecting pipe. The filter element, which can be made of activated carbon, absorbs harmful substances in the exhaust gas. The inlet can be connected to other pipes through the first flange and the second flange.

[0011] Furthermore, a connection structure is installed on one side of the inlet. The connection structure includes a second flange installed on one side of the inlet, a first flange installed on one side of the second flange, a sealing block installed on one side of the first flange, a sealing ring installed on one side inside the second flange, a mounting screw installed on one side of the first flange, and a nut installed on one side of the mounting screw. The inlet can be connected to other pipes through the flange.

[0012] Furthermore, the outer side wall of the mounting screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The mounting screw and the nut are threadedly connected, and the mounting screw and the nut can fix the first flange and the second flange together.

[0013] Furthermore, the nuts are arranged in a ring shape, and the nuts are arranged at equal intervals on one side of the second flange.

[0014] Furthermore, the top of the cleaning box is equipped with a disassembly structure, which includes an opening installed at the top of the cleaning box, a cover installed at the top of the opening, a rubber ring installed at the bottom of the cover, a fixing plate installed on the outside of the opening, and a rotating shaft installed on the inside of the fixing plate. The filter element can be replaced by opening the cover.

[0015] Furthermore, a locking block is provided at the bottom of the cover, and a locking groove is provided at the top of the opening. The cover and the opening form a locking structure, which facilitates disassembly.

[0016] Furthermore, a snap fastener is installed at the top of the rotating shaft. The snap fastener is arranged in a ring and can fix the cover.

[0017] The advantages of the reaction vessel exhaust gas treatment device provided by this utility model are: during use, the exhaust gas on the filter side can also be sent into the filter box through the conduit for multiple filtrations and purifications, so as to improve the filtration effect. At the same time, when the filter element needs to be replaced, the cover can be moved to replace the filter element through the opening.

[0018] By installing an inlet at the top of the outlet, the outlet valve is closed before the exhaust gas is discharged. Then, the pump body works to generate suction, which can draw the cleaned exhaust gas out through the inlet. The exhaust gas is then transported to the outlet through a conduit and sent to the filter box through the outlet. The exhaust gas can then be filtered again through the filter box and the filter element is cleaned. This allows the exhaust gas to be cleaned multiple times, resulting in a better cleaning effect. This achieves the purpose of the reactor exhaust gas emission treatment device to facilitate the recycling of exhaust gas.

[0019] An opening is installed at the top of the cleaning chamber, which is sealed by a cover. The rubber ring at the bottom of the cover enhances the seal. The rotating shaft inside the fixing plate can rotate, and the rotation of the shaft will cause the buckle to lock the cover in place. When the filter element needs to be replaced, the buckle is rotated to release it from the cover, allowing the cover to be opened and the filter element to be replaced through the opening. This achieves the purpose of facilitating filter element replacement in the reactor exhaust gas treatment device. Attached Figure Description

[0029] Nuts 304 are installed on one side of the mounting screws 303. The nuts 304 are distributed in a ring and are arranged at equal intervals on one side of the second flange 302.

[0030] See attached document Figure 1-2 and attached Figure 4 As shown, during use, after the exhaust gas is loaded into the filter box 1 through inlet 2, the filter screen can filter the exhaust gas and the dust inside. After filtration by the filter screen inside the filter box 1, the discharge pump 5 will drive the filtered exhaust gas into the cleaning box 7 through the connecting pipe 6. After filtration by the filter element 8, which can be made of activated carbon material, the filter element 8 can absorb harmful substances inside the exhaust gas.
