Description

Technical Field

[0001] This utility model belongs to the technical field of graphite-based hydrogen chloride production integrated absorption tower, and particularly relates to a graphite-based hydrogen chloride production integrated absorption tower. Background Technology

[0002] An absorption tower is a device used to perform absorption operations. Based on the gas-liquid phase contact pattern, they are classified into three categories. The first category includes plate towers, bubbling absorption towers, and stirred bubbling absorption towers where the gas is dispersed in the liquid phase as bubbles. The second category includes ejectors, venturi tubes, and spray towers where the liquid is dispersed in the gas phase as droplets. The third category includes packed absorption towers and falling film absorption towers where the liquid contacts the gas phase in a film-like motion. The flow patterns of the gas and liquid phases within the tower can be either countercurrent or cocurrent.

[0003] When assembling the absorption tower, bolts need to be passed through the mounting holes, and then nuts need to be screwed onto the bolts. Two wrenches are then used to tighten the nuts and bolts. Because the nuts are relatively unstable and easily fall off, the assembly of the absorption tower is quite troublesome.

[0004] Therefore, we propose a graphite-based integrated absorption tower for producing hydrogen chloride to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of complicated absorption tower assembly, and to propose a graphite-based integrated absorption tower for producing hydrogen chloride.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A graphite-based hydrogen chloride production absorption tower includes an absorption tower body. A first nut clamping bracket and a second nut clamping bracket are provided on the outer side of the flange of the absorption tower body. The first nut clamping bracket and the second nut clamping bracket are fastened together and clamped onto the absorption tower body. A first spring clip is fixedly connected to each of the first nut clamping bracket and the second nut clamping bracket. During assembly of the absorption tower body, the first nut clamping bracket and the second nut clamping bracket are used to fix the nut position. Bolts are passed through the flange of the absorption tower body, and the nut is tightened. During tightening, the first nut clamping bracket and the second nut clamping bracket prevent the nut from rotating, thereby facilitating the assembly of the absorption tower body.

[0008] Preferably, the first nut restraint bracket includes a first arc-shaped plate and a second spring plate, and the lower end of the first arc-shaped plate has a first hexagonal groove. The nut is clamped in the first hexagonal groove, and the first spring plate blocks the lower end of the nut, so that the nut is stabilized in the first hexagonal groove, which facilitates the tightening of the target bolt.

[0009] Preferably, the first nut restraint frame further includes a first pressure block, which is fixedly connected to the lower part of the second spring sheet. The elastic force of the second spring sheet acts on the first pressure block, causing it to press against the outer wall of the absorption tower body, increasing the friction between the first nut restraint frame and the absorption tower body, and improving the stability of the first nut restraint frame's position.

[0010] Preferably, the second nut restraint frame includes a second arc-shaped plate, a third spring piece, and a spring clip. The lower end of the second arc-shaped plate has a second hexagonal groove, and the third spring piece is fixedly connected to the lower end of the second arc-shaped plate. The spring clip is fastened to the first arc-shaped plate, so that the first nut restraint frame and the second nut restraint frame form a ring, which facilitates the first nut restraint frame and the second nut restraint frame to be held around the body of the absorption tower.

[0011] Preferably, the second nut restraint frame further includes a second pressure block, which is fixedly connected to the lower part of the third spring sheet. The elastic force of the third spring sheet acts on the second pressure block, causing it to press against the outer wall of the absorption tower body, increasing the stability of the second nut restraint frame's position.

[0012] Preferably, the first spring includes a spring strip and a connecting block, with the connecting block fixedly connected to the upper end of the spring strip. The spring strip blocks the lower end of the nut, preventing the nut from falling out of the first or second hexagonal groove.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. When assembling the absorption tower body, the first nut restraint bracket and the second nut restraint bracket are used to fix the position of the nut. The bolt is passed through the flange of the absorption tower body and the nut is tightened inside. When tightening, the first nut restraint bracket and the second nut restraint bracket prevent the nut from rotating, thus facilitating the assembly of the absorption tower body.

[0015] 2. Secure the nut in the first hexagonal groove, and use the first spring clip to block the lower end of the nut, so that the nut is stabilized in the first hexagonal groove, making it easy to tighten the target bolt.

[0016] 3. The elastic force of the second spring plate acts on the first pressure block, causing the first pressure block to press against the outer wall of the absorption tower body, increasing the friction between the first nut binding frame and the absorption tower body, and improving the stability of the position of the first nut binding frame.

[0017] 4. Connect the spring clip to the first arc-shaped plate to form a ring with the first nut binding frame and the second nut binding frame, so that the first nut binding frame and the second nut binding frame can be held around the body of the absorption tower.

[0018] 5. The elastic force of the third spring plate acts on the second pressure block, causing the second pressure block to press against the outer wall of the absorption tower body, thereby increasing the stability of the second nut binding frame position. Attached Figure Description
