Description

Technical Field

[0001] The present application relates to the technical field of anti-clogging, and in particular to an anti-clogging structure for an exhaust pipe of a primary sulfidation reaction tank. Background Art

[0002] The primary sulfide reaction tank is the first process of the sulfide dearsenicization system. The dirty acid and sodium hydrosulfide reagent react chemically in the reaction tank. The liquid after the reaction automatically overflows into the slurry tank and enters the subsequent process for treatment. The hydrogen sulfide gas produced by the reaction is drawn by the blower of the harm removal tower to the desorption tower system for treatment and then meets the emission standards.

[0003] To prevent harmful gases from escaping and potentially causing personal injury, the primary sulfidation reactor for water supply and drainage utilizes a fully sealed negative pressure exhaust system. However, because the negative pressure exhaust pipe is located close to the tank surface, impurities within the reactor are easily drawn into the pipe, leading to frequent blockages.

[0008] There is a distance between the negative pressure exhaust pipe on the upper part of the accumulation tube and the reaction tank, so that the impurities are sucked up and accumulated on the wall of the accumulation tube, and fall back into the reaction tank by their own weight.

[0028] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0029] Example 1:

[0030] See also Figure 1 A blockage prevention structure for a primary vulcanization reaction tank exhaust pipe includes a reaction tank 1 and a negative pressure exhaust pipe 2. The blockage prevention structure for a primary vulcanization reaction tank exhaust pipe further includes:

[0031] The accumulation tube 3 is installed at the closed hole of the reaction tank 1, and the upper side wall of the accumulation tube 3 is connected to the negative pressure exhaust pipe 2 through the joint 4;

[0032] There is a distance between the negative pressure exhaust pipe 2 on the upper part of the accumulation tube 3 and the reaction tank 1 so that the impurities are accumulated on the wall of the accumulation tube 3 when they are sucked up and fall back into the reaction tank 1 by their own weight.

[0033] Specifically, the accumulation tube 3 is installed at the sealed hole of the reaction tank 1 to connect the two. The connection between the two should be sealed to prevent gas leakage. The upper side wall of the accumulation tube 3 is provided with a mounting hole, and a mounting tube 5 is fixed in the mounting hole. One end of the joint 4 is connected to the mounting tube 5, and the other end is connected to the negative pressure exhaust pipe 2. In this way, the connection between the negative pressure exhaust pipe 2 and the reaction tank 1 is achieved. The negative pressure exhaust pipe 2 is set on the upper side wall of the accumulation tube 3 so that it forms a certain distance with the reaction tank 1, so that when the negative pressure exhaust pipe 2 is exhausting air, impurities are sucked up and accumulated in the wall of the accumulation tube 3, and fall back into the reaction tank 1 by their own weight, thereby preventing impurities from entering the negative pressure exhaust pipe 2 and causing blockage.

[0034] In addition, in order to further prevent the negative pressure exhaust pipe 2 from being blocked, a filter screen can be set in the installation pipe, and the filter screen is made of corrosion-resistant material.

[0035] Example 2:

[0036] See also Figure 1 and Figure 2 Based on the first embodiment, optionally, a mounting tube 5 is provided on the upper side wall of the accumulation cylinder 3 , one end of the mounting tube 5 is connected to the interior of the accumulation cylinder 3 , and the other end is connected to one end of the joint 4 through a first flange 6 .

[0037] Specifically, the diameter of the mounting tube 5 matches the diameter of the end of the connector 4 near the first flange 6, and the two are sealed together via the first flange 6. The flange connection utilizes a flange gasket at the joint. This gasket is typically made of a flexible, resistant material that effectively prevents leakage and achieves high sealing performance. Furthermore, the flange connection facilitates installation and removal.

[0038] Optionally, the other end of the joint 4 is connected to the negative pressure exhaust pipe 2 through a second flange 7 .

[0039] Specifically, the end of the connector 4 near the second flange 7 matches the diameter of the negative pressure exhaust pipe 2, and the two are sealed together through the second flange 7. The flange connection uses a flange gasket at the joint. This gasket is usually made of a flexible and resistant material that can effectively prevent medium leakage and achieve high sealing performance. At the same time, the flange connection is easy to install and disassemble.

[0040] Optionally, the diameter of the end of the joint 4 close to the first flange 6 is larger than the diameter of the end away from the first flange 6, so as to form a reducing joint.

[0041] Specifically, since the diameter of the mounting tube 5 is larger than that of the negative pressure exhaust pipe 2, a reducer is used to facilitate the connection between the two. Furthermore, the middle portion of the reducer is transitioned into an arc to reduce stress concentration and improve structural strength.

[0042] Optionally, the accumulation cylinder 3 is a glass fiber reinforced plastic cylinder with a height of 100 mm and a DN of 600.

[0043] Specifically, the nominal diameter of the accumulation tube 3 is selected based on the aperture of the closed hole in the reaction tank 1. It should be larger than the aperture of the closed hole to prevent air leakage. A 100mm height ensures that impurities are absorbed and deposited within the tube 3 wall, returning to the reaction tank 1 under their own weight. Fiberglass reinforced plastics offer high strength and corrosion resistance, ensuring a long service life.

[0044] It should be noted that the height of the accumulation tube 3 is not limited to 100 mm. It can be slightly lower than 100 mm or higher than 100 mm. In short, as long as it can ensure that the impurities are sucked up and accumulated in the wall of the accumulation tube 3, and do not enter the negative pressure exhaust pipe 2, it will be fine.

[0045] Optionally, the bottom of the accumulation cylinder 3 is installed at the closed hole of the reaction tank 1 through a sealing strip 8.

[0046] Specifically, a fixing ring 9 is fixed to the bottom of the accumulation cylinder 3, and sealing strips 8 are arranged in a circumferential array at equal intervals on the fixing ring 9 to achieve uniform force. One end of the sealing strip 8 is fixed to the reaction tank 1, and the other end elastically presses against the fixing ring 9 to achieve sealing.

[0047] Furthermore, at least four groups of sealing strips 8 are provided.

[0048] Optionally, the sealing strip 8 is a spring steel sealing strip.

[0049] Specifically, spring steel sealing strips are made from spring steel, a material with excellent elasticity and corrosion resistance. When installed where sealing is required, the strip adapts to even minor irregularities in the sealing surface through its own elastic deformation, achieving a tight fit. When affected by external factors such as pressure or temperature, the strip maintains a certain degree of resilience, ensuring a durable seal. This tight fit and resilience effectively prevent media from leaking through tiny gaps in the sealing surface. Spring steel sealing strips can significantly improve the sealing performance of joints. Due to their excellent elasticity and corrosion resistance, they can adapt to a variety of complex working environments, such as high temperature, high pressure, acid and alkali conditions, ensuring the stability and reliability of the sealing effect.

[0050] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.

[0051] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
