Sleeving shell of round block hole type graphite heat exchanger and production process thereof

Abstract

The invention discloses a sleeving shell of a round block hole type graphite heat exchanger and a production process thereof. The sleeving shell structurally comprises a water inlet pipe and a water outlet pipe, a plurality of annular protrusions are distributed on a middle shell body from top to bottom, an upper flange cover extends outwards to form an upper fixing plate, and a lower flange coverextends outwards to form a lower fixing plate; the water inlet pipe is fixed to the upper fixing plate and perpendicularly penetrate through the interiors of the annular protrusions downwards one byone, and a plurality of water inlets communicating with the annular protrusions one by one are formed in the water inlet pipe; and the water outlet pipe is fixed to the lower fixing plate and perpendicularly penetrates through the interiors of the annular protrusions upwards one by one, a plurality of water outlets communicating with the annular protrusions one by one are formed in the water outlet pipe, and the water inlet pipe and the water outlet pipe are oppositely arranged at the two sides of the middle shell body. According to the sleeving shell, rapid water inlet and rapid water outletin a flow guide groove are achieved through the multiple water inlets and the multiple water outlets, the circulation efficiency of cooling water in the middle shell body is improved, and therefore, the heat exchange efficiency of the cooling water and waste gas is ensured.

Description

Technical field: [0001] The invention relates to the technical field of production of graphite heat exchangers, in particular to a sleeve shell of a round hole graphite heat exchanger and a production process thereof. Background technique: [0002] Graphite heat exchanger is a heat exchanger made of graphite for heat transfer components. The working principle of graphite heat exchanger is: according to the acid corrosion resistance and good thermal conductivity of graphite, graphite heat exchange block is made of graphite. When two media When passing through each other, the high-temperature medium continuously transfers heat to the graphite heat exchanger, and the low-temperature medium continuously obtains heat from the heat exchanger, thereby realizing heat exchange. According to the characteristics of graphite, graphite heat exchangers are increasingly widely used in cold rolling pickling line, chemical industry, petroleum and pesticide industries. Traditional graphite h...

Problems solved by technology

[0003] At present, the inflow and outflow of low-temperature medium inside the casing is generally realized by opening water inlets and outlets on the casing. When the low-temperature medium actually flows in or out, the flow rate of the low-temperature medium is relatively slow, resulting in low-temperature medium The internal circulation efficiency of the casing is low, which causes heat to accumulate inside the casing, making it difficult to meet the heat exchange needs of graphite heat exchangers
