Description

TECHNICAL FIELD

[0001] The utility model relates to condenser technical field especially a kind of anti-blocking graphite condenser. BACKGROUND

[0002] In the industrial production field such as chemical industry, pharmaceutical, graphite condenser is widely used in various cooling, condensing process by virtue of its good corrosion resistance and heat exchange efficiency. However, the existing graphite condenser has a serious plugging problem in actual use. Because the high-temperature steam medium handled often contains solid particles, crystalline or impurities, in the condensation process, these substances are easy to gradually accumulate in the pipeline or heat exchange channel of graphite condenser, and the plugging situation becomes more and more serious with time.

[0003] The plugging problem not only significantly reduces the heat exchange efficiency of graphite condenser, but also causes the increase of equipment operating energy consumption, and increases the risk of equipment damage, and even may cause production safety accident.

[0004] For example, a kind of graphite condenser is disclosed in the patent application No. CN202222839827.4, which mainly includes condensing barrel, air inlet pipe, graphite pipe, circular shell, exhaust pipe, condensate discharge pipe, cooling water input pipe, cooling water output pipe and other key components.

[0005] As can be seen, when condensing high-temperature steam, high-temperature steam needs to pass through each graphite pipe in the center, and the cooling water is supplied into the internal space of the condensing barrel by circulating the external cooling water input pipe and cooling water output pipe. This external condensing method is more likely to cause scaling and plugging problems, mainly due to the following reasons:

[0006] When high-temperature steam passes through each graphite pipe with a small diameter, impurities inside the graphite pipe are easy to accumulate on the inner wall of the graphite pipe during the condensation process, which causes long-term plugging of the graphite pipe.

[0007] Because the internal space of the graphite pipe is small, the structure will be blocked soon, which causes the need to clean the internal graphite pipe frequently, increasing the maintenance workload.

[0008] Due to the small internal space of the graphite pipe, only the method of passing in descaling agent can be used for cleaning at present, and the cleaning effect is poor, which also increases the subsequent maintenance frequency.

[0009] Based on this, it can be found that the existing graphite condenser has the problems of easy plugging, high cleaning frequency and difficult cleaning. Therefore, it is necessary to design a new type of graphite condenser which can be quickly cleaned and reduce the frequency of scaling and plugging. UTILITY MODEL CONTENT

[0059] Working process:

[0060] High-temperature steam medium input: The high-temperature steam medium enters the condensation cavity through the material pipe located at the lower outer sidewall of the left outer vertical cylinder. Since the condenser comprises two symmetrically and spaced condenser units and the upper condenser units are connected through the connecting pipe, the steam medium can first pass through the left condensation cavity and then pass through the right condensation cavity.

[0061] Cooling process: the cooling liquid enters the cooling liquid inlet cavity through the cooling liquid inlet pipe connected with the external cooling pipeline. The cooling liquid inlet cavity is located in the cavity on the top of the upper sealing disc, and the cooling liquid flows into the graphite cooling group. The graphite cooling group is composed of a plurality of graphite cooling pipes arranged in an array inside the condensation cavity, and the top of each graphite cooling pipe is sealingly fixed on the top of the upper sealing disc and communicates with the cooling liquid inlet cavity. The cooling liquid flows in the graphite cooling pipe and exchanges heat with the high-temperature steam medium in the condensation cavity to cool the steam medium.

[0062] The cooled cooling liquid flows into the cooling liquid discharge cavity from the bottom of the graphite cooling pipe. The cooling liquid discharge cavity is located in the cavity on the bottom of the lower sealing disc, and then is discharged through the cooling liquid discharge pipe on the outer lateral wall of the lower part of the outer cylinder and is connected with the external liquid discharge pipeline to complete the cooling liquid circulation.

[0063] Cooling gas discharge: the cooled gas is discharged from the material pipe on the outer lateral wall of the lower part of the right outer cylinder.

[0064] Condensate treatment: the condensate generated in the steam medium cooling process accumulates in the lower part of the outer cylinder. When it is necessary to discharge, the plug on the condensate discharge joint on the outer lateral wall of the lower part of the outer cylinder is opened, and the condensate can be discharged. After the liquid is discharged, the plug is reinstalled to prevent leakage.

[0065] Cleaning and maintenance: when the condenser needs to be cleaned, a cleaning agent is soaked into the condensation cavity. The lifting ring on the top of the lifting column is connected by the external lifting equipment, and the lifting ring is driven to move up and down, and the lifting column drives the scraping disc to move up and down in the condensation cavity. The outer lateral wall of the scraping disc abuts against the inner cavity lateral wall of the outer cylinder, and the circular hole arranged on the surface of the scraping disc movably sleeves the outer lateral wall of the graphite cooling pipe, so that the outer lateral wall of the graphite cooling pipe can be scraped. At the same time, the flow guide hole on the surface of the scraping disc can make the cleaning agent flow more uniformly in the condensation cavity, and the cleaning effect is enhanced.
