Description

Technical Field

[0001] This utility model relates to the field of vaporizer pipeline technology, specifically to a vaporizer operating pipeline structure. Background Technology

[0002] After ethylene oxide sterilization, residual ethylene oxide gas remains in the product, which can be harmful to personnel and does not meet the requirements of GB16886.7. Traditional natural desorption and volatilization takes a long time, typically 7-60 days, preventing the product from being marketed quickly. Rapid desorption equipment for ethylene oxide sterilization, through temperature control and negative pressure removal ventilation, can rapidly volatilize the ethylene oxide in the product, shortening the desorption time to 0.5-7 days. This involves the use of vaporizers. To meet the needs of industrial production and safety requirements, multiple ethylene oxide sterilization units are often concentrated in a fixed ethylene oxide injection area during actual production. This injection area may be tens to hundreds of meters away from the equipment. Due to incomplete vaporization, long-distance transmission, or low ambient temperature, the ethylene oxide gas may not completely vaporize upon entering the sterilization cabinet, affecting the sterilization effect and failing to meet regulatory requirements.

[0003] Conventional ethylene oxide pipelines are single-layered pipes, with gas passing through the inside. Vaporization liner pipes are double-layered, with the inner pipe carrying ethylene oxide gas and the outer pipe and the interlayer between the inner and outer pipe carrying circulating hot water. This design allows for continuous vaporization within the liner pipe over long distances if the upstream vaporizer's vaporization is insufficient. Furthermore, it is unaffected by low external temperatures, preventing the gas from condensing into liquid due to the low ambient temperature during transport. Additionally, testing the pipeline's tightness during operation is difficult. Therefore, a new vaporizer operating pipeline structure is needed. Utility Model Content

[0004] The purpose of this invention is to provide a vaporizer operating pipeline structure to solve the problems of gas turning into liquid due to low ambient temperature during the gas transmission process in existing structures, and the difficulty in testing the pipeline's airtightness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vaporizer operating pipeline structure, comprising several straight pipes and several bends, with flange rings fixedly installed at both ends of the straight pipes and bends, and protective mechanisms provided on the straight pipes and bends; the protective mechanisms include thermal insulation cotton, which is clamped to the outside of the straight pipes, with two protective long plates clamped to the outside of the straight pipes, and two protective folding plates clamped to the outside of the bends, with fixing plates fixedly installed on both the protective folding plates and the protective long plates, and several fastening bolts fixedly installed through the two flange rings and the two fixing plates.

[0006] Preferably, both flange rings are coated with adhesive between themselves and the two fixing plates, and the outer diameter of the flange rings is smaller than the inner diameter of the protective long plate and the protective folding plate.

[0007] Preferably, the curvature of the bend in the pipe is consistent with that of the protective folding plate, and the insulation cotton is composed of an arc-shaped plate.

[0008] Preferably, the protective long plate and the protective folding plate both have semi-circular cross-sections, and the fixing plate is protrudingly mounted on the protective long plate and the protective folding plate.

[0009] Preferably, both the protective long plate and the protective folding plate are provided with a detection mechanism. The detection mechanism includes an air tube, which is fixedly installed on the protective long plate and the protective folding plate. Two sealing gaskets are fixedly installed side by side at both ends of the protective long plate and the protective folding plate. A plug is embedded in the air tube, and a fixing frame is fixedly installed on one side of the air tube. A miniature trigger is fixedly installed at one end of the fixing frame.

[0010] Preferably, the sealing gasket is tightly attached to the straight pipe and the bend, and the plug is adapted to the input terminal of the micro trigger.

[0011] Preferably, a plurality of protruding rings are fixedly installed side by side on the outside of the plug, and the trachea is adapted to the plurality of protruding rings.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) The vaporizer's operating pipeline structure connects the straight pipe and the bend by controlling the fastening bolts and flange rings. After wrapping the outside of the straight pipe with heat insulation cotton, the protective long plate and protective folding plate are clamped on the outside of the straight pipe and the bend respectively by the fastening bolts, thereby achieving heat insulation and protection of the pipeline. This avoids the phenomenon of incomplete vaporization of ethylene oxide gas caused by low temperature environment during long-distance transmission, and also avoids damage to the pipeline from impacts.

[0014] 2) The vaporizer's operating pipeline structure includes a gas pipe installed on a protective long plate and a protective folding plate, with a plug embedded inside the gas pipe. Under the action of gas pressure, the plug moves up and down along the gas pipe. When there is a leak in the straight pipe or bend and its joint, the pressure inside the protective long plate or protective folding plate will increase, causing the plug to move out of the gas pipe. When the plug is released to the input end of the micro trigger, the signal of pipeline leakage will be transmitted to the vaporizer control system through the micro trigger for accurate detection of the leak location in the pipeline.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-3 A vaporizer operating pipeline structure includes several straight pipes 1 and several bends 2. Flange rings 3 are fixedly installed at both ends of the straight pipes 1 and the bends 2. Protective mechanisms 4 are provided on both the straight pipes 1 and the bends 2. The protective mechanism 4 includes thermal insulation cotton 401, which is clamped to the outside of the straight pipes 1. Two protective long plates 402 are clamped to the outside of the straight pipes 1, and two protective folding plates 403 are clamped to the outside of the bends 2. Fixing plates 404 are fixedly installed on both the protective folding plates 403 and the protective long plates 402. Several fastening bolts 405 are fixedly installed through the two flange rings 3 and the two fixing plates 404.

[0024] Adhesive is applied between the two flange rings 3 and the two fixing plates 404. The adhesive application increases the tightness of the connection between the flange rings 3 and the fixing plates 404, preventing gaps from appearing at the connection between the straight pipe 1 and the bend 2. The outer diameter of the connecting flange ring 3 is smaller than the inner diameter of the protective long plate 402 and the protective folding plate 403. The cross-sections of the protective long plate 402 and the protective folding plate 403 are both semi-circular rings. The fixing plate 404 is protrudingly installed on the protective long plate 402 and the protective folding plate 403, ensuring that the protective long plate 402 and the protective folding plate 403 can be fastened to the straight pipe 1 and the bend 2 respectively. The curvature of the bend 2 is consistent with that of the protective folding plate 403. The thermal insulation cotton 401 is composed of arc-shaped plates, allowing the thermal insulation cotton 401 to wrap around the outside of the straight pipe 1.

[0025] Example 2

[0026] See Figure 4 and Figure 5 Both the protective long plate 402 and the protective folding plate 403 are equipped with a detection mechanism 5. The detection mechanism 5 includes an air pipe 501, which is fixedly installed on the protective long plate 402 and the protective folding plate 403. Two sealing gaskets 502 are fixedly installed side by side at both ends of the protective long plate 402 and the protective folding plate 403. A plug 503 is embedded in the air pipe 501, and a fixing frame 504 is fixedly installed on one side of the air pipe 501. A miniature trigger 505 is fixedly installed at one end of the fixing frame 504.

[0027] The sealing gasket 502 is tightly attached to the straight pipe 1 and the bend 2 to improve the sealing performance of the protective long plate 402 and the protective folding plate 403. The plug 503 is adapted to the input end of the micro trigger 505. Several convex rings are fixedly installed in parallel on the outside of the plug 503, and the air pipe 501 is adapted to several convex rings. When the straight pipe 1 or the bend 2 leaks, the pressure inside the protective long plate 402 and the protective folding plate 403 will increase, which will cause the plug 503 to move outward along the air pipe 501. When the plug 503 is released to the input end of the micro trigger 505, the signal of pipeline leakage will be transmitted to the vaporizer control system through the micro trigger 505 for accurate detection of the pipeline leakage location. Among them, several protective long plates 402 are intermittently fixedly installed in parallel on the outside of the straight pipe 1.

[0028] In actual operation, the straight pipe 1 and the bend 2 are connected by controlling the fastening bolts 405 and the flange ring 3. After wrapping the outside of the straight pipe 1 with thermal insulation cotton 401, the protective long plate 402 and the protective folding plate 403 are clamped on the outside of the straight pipe 1 and the bend 2 respectively by using the fastening bolts 405. This achieves thermal insulation and protection of the pipeline, avoids the phenomenon of incomplete vaporization of ethylene oxide gas caused by low temperature environment during long-distance transmission, and avoids damage to the pipeline from impacts.

[0029] An air pipe 501 is installed on the protective long plate 402 and the protective folding plate 403, and a sealing plug 503 is embedded inside the air pipe 501. Under the action of air pressure, the sealing plug 503 moves up and down along the air pipe 501. When the straight pipe 1 or the bend pipe 2 and its joint leak, the pressure inside the protective long plate 402 or the protective folding plate 403 will increase, which will cause the sealing plug 503 to move out of the air pipe 501. When the sealing plug 503 is released to the input end of the micro trigger 505, the signal of pipeline leakage will be transmitted to the vaporizer control system through the micro trigger 505 for accurate detection of the pipeline leakage location.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
