Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a multi-stage circulating condensation treatment device for laboratory waste gas treatment. Background Technology

[0002] Experiments in laboratory fume hoods often produce volatile waste gases, which are liquefied by a condenser at the top of the hood for easy cleaning. The inner tube of the condenser usually has two output tubes: one for liquefied waste gas and the other for other waste gases that will not liquefy. However, unliquefied waste gas is prone to flow into the collection bottle along with the liquid waste gas and then be released into the external environment, polluting the environment.

[0003] According to patent document CN220837138U, this device uses a fan to draw non-liquefied waste gas into a filter box for filtration, preventing non-liquefied waste gas from entering the collection bottle along with liquefied waste gas and polluting the surrounding environment, thus increasing the filtration performance of the fume hood. However, in the aforementioned patent document, the condenser tube will be damaged after long-term use, so regular inspection of the condenser tube is required. When the condenser tube is damaged, the entire condenser circulation pipeline needs to be replaced, and the undamaged pipes are also replaced at the same time, resulting in waste. It is impossible to replace the damaged pipes specifically according to the damaged parts, extend the overall service life of the condenser box, and avoid unnecessary waste.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a multi-stage circulating condensation treatment device for laboratory waste gas treatment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-stage circulating condensation treatment device for laboratory waste gas treatment includes a condensation chamber, wherein an inlet pipe is provided at the input end of the condensation chamber, an outlet pipe is provided at the output end of the condensation chamber, and a detachable condensate circulation mechanism is provided inside the condensation chamber.

[0008] The circulation mechanism includes an inlet pipe vertically inserted at the top of the condenser, the output end of which extends into the condenser. The condenser is equipped with multiple sets of sequentially interconnected lower and upper conveying pipes. The input end of the lower conveying pipe near the inlet pipe is connected to the inlet pipe. An outlet pipe is also vertically inserted at the top of the condenser, and the output end of the upper conveying pipe near the outlet pipe is connected to the outlet pipe.

[0009] Furthermore, both the lower conveying pipe and the upper conveying pipe have U-shaped cross-sections.

[0010] Furthermore, the ends of the lower conveying pipe, the upper conveying pipe, the bottom of the inlet pipe, and the bottom of the outlet pipe are all provided with locking rings, and two sets of upper fixing blocks are provided on the outer sides of the two locking rings respectively.

[0011] Furthermore, the cross-section of the two sets of upper fixing blocks is semi-circular, and upper mounting plates are fixedly installed on the opposite side walls of the two upper fixing blocks. The two upper mounting plates are fixedly connected on opposite sides by a connecting threaded rod.

[0012] Furthermore, a lower mounting plate is provided below the upper mounting plate. A lower fixing block is fixedly provided on the outer wall of the lower mounting plate corresponding to the lower conveying pipe. The lower fixing block is tightly fitted to the side wall of the lower conveying pipe. The upper mounting plate and the lower mounting plate are fixedly connected by multiple sets of mounting vertical plates. Both sides of the two lower mounting plates are connected by connecting threaded rods.

[0013] Furthermore, a collection pipe is inserted into the bottom of the condenser box, and the outer wall of the collection pipe is wrapped around the outer wall of the air intake pipe.

[0014] Furthermore, a purification box is provided at the output end of the air outlet pipe.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model uses condensate inside the lower and upper conveying pipes to cool and release heat from the waste gas. The liquefiable waste gas is liquefied into liquid and collected through the collection pipe. The non-liquefiable waste gas is discharged through the outlet pipe and enters the purification box for purification. The collected liquefied liquid provides initial cooling for the waste gas. Then, the waste gas is circulated and cooled again through the upper and lower conveying pipes inside the condensation box, achieving multi-stage circulating cooling of the waste gas.

[0017] 2. This utility model involves rotating the bolts on the top wall of the condenser to simultaneously remove the pipes inside the condenser. Then, by rotating the connecting threaded rod one and the connecting threaded rod two, the fixing of the two upper and lower mounting plates can be released. This allows the upper and lower fixing blocks to be separated, thereby completing the disassembly of the lower and upper conveying pipes. This enables targeted replacement of the damaged parts of the pipes, extending the overall service life of the condenser. Attached Figure Description

[0024] 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.

[0025] Example 1: As Figure 1-5 As shown, the multi-stage circulating condensation treatment equipment for laboratory waste gas treatment proposed in this embodiment includes a condensation box 2, an inlet pipe 1 at the input end of the condensation box 2, an outlet pipe 3 at the output end of the condensation box 2, and a detachable condensate circulation mechanism 5 inside the condensation box 2.

[0026] like Figure 1-5 As shown, the circulation mechanism 5 includes an inlet pipe 51 vertically inserted at the top of the condenser 2. The output end of the inlet pipe 51 extends into the condenser 2. The condenser 2 is provided with multiple sets of lower conveying pipes 52 and upper conveying pipes 53 that are connected to each other in sequence. The input end of one of the lower conveying pipes 52, which is close to the inlet pipe 51, is connected to the inlet pipe 51. An outlet pipe 54 is also vertically inserted at the top of the condenser 2. The output end of one of the upper conveying pipes 53, which is close to the outlet pipe 54, is connected to the outlet pipe 54.

[0027] It should be noted that: the condensate enters the condensation chamber 2 through the liquid inlet pipe 51, passes through multiple sets of upper conveying pipes 53 and lower conveying pipes 52, and is then discharged through the liquid outlet pipe 54, thus achieving the function of condensing laboratory waste.

[0028] Furthermore, both the lower conveying pipe 52 and the upper conveying pipe 53 have U-shaped cross-sections;

[0029] like Figure 2-5 As shown, the end of the lower conveying pipe 52, the end of the upper conveying pipe 53, the bottom of the inlet pipe 51, and the bottom of the outlet pipe 54 are all provided with locking rings 59, and two sets of upper fixing blocks 55 are provided on the corresponding outer sides of the two locking rings 59.

[0030] like Figure 2-5 As shown, the cross-section of the two sets of upper fixing blocks 55 is semi-circular, which serves to seal the two locking rings 59. Upper mounting horizontal plates 56 are fixedly installed on the opposite side walls of the two upper fixing blocks 55. The two upper mounting horizontal plates 56 are fixedly connected on opposite sides by connecting threaded rods 58, and the ends of the connecting threaded rods 58 are threaded with nuts to fix the two upper mounting horizontal plates 56.

[0031] like Figure 2-5 As shown, a lower mounting plate is provided below the upper mounting plate 56. A lower fixing block is fixedly provided on the outer wall of the lower mounting plate corresponding to the lower conveying pipe 52. The lower fixing block is tightly fitted to the side wall of the lower conveying pipe 52. The upper mounting plate 56 and the lower mounting plate are fixedly connected by multiple sets of mounting vertical plates 57. Both sides of the two lower mounting plates are connected by connecting threaded rods.

[0032] It should be noted that the top wall of the condenser box 2 is connected to the main body of the condenser box 2 by bolts.

[0033] like Figure 1-5 As shown, a collection pipe 6 is inserted at the bottom of the condenser box 2. The outer wall of the collection pipe 6 is wrapped around the outer wall of the air inlet pipe 1, which serves to initially cool the air inlet pipe 1.

[0034] like Figure 1-5 As shown, the output end of the exhaust pipe 3 is equipped with a purification box 4, which is used to purify laboratory exhaust gas. It should be noted that the purification box 4 is internally fitted with an activated carbon filter plate, a nylon mesh filter, and a glass fiber filter plate. It is a functional device for purifying exhaust gas in the prior art, and will not be described in detail here.

[0035] Working principle: When this utility model is in use, the waste gas generated in the laboratory enters the condenser box 2 through the inlet pipe 1. The waste gas is cooled and heat-releasing by the condensate inside the lower conveying pipe 52 and the upper conveying pipe 53. The liquefiable waste gas is liquefied into liquid and recycled through the collection pipe 6. The non-liquefiable waste gas is discharged through the outlet pipe 3 and enters the purification box 4 for purification. The collected liquefied liquid performs preliminary cooling treatment on the waste gas. Then, the waste gas is circulated and cooled again through the upper conveying pipe 53 and the lower conveying pipe 52 inside the condenser box 2, realizing multi-stage circulating cooling of the waste gas.

[0036] When the condenser 2 needs to be replaced or its internal upper conveying pipe 53 and lower conveying pipe 52 need to be inspected after long-term use, the pipes inside the condenser 2 can be moved out simultaneously by rotating the bolts on the top wall of the condenser 2. Then, by rotating the connecting threaded rod 1 58 and connecting threaded rod 2, the fixation of the two upper mounting plates 56 and the lower mounting plates can be released. In this way, the upper fixing block 55 and the lower fixing block can be separated, thereby completing the disassembly of the lower conveying pipe 53 and the upper conveying pipe 52. Then, the pipes can be replaced according to the damaged parts, thus extending the overall service life of the condenser 2.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
