[0003] At present, the structure of the graphite heat exchange block is generally to open a number of longitudinal holes inside the cylindrical graphite block to provide passages for the exhaust gas to flow. In the actual use of this graphite heat exchanger, the flow rate of the exhaust gas in the longitudinal holes is too fast, which is difficult. Form sufficient heat exchange with the external low-temperature medium, and the heat exchange effect is poor

The invention discloses a heat exchange block of a round block hole type graphite heat exchanger and a production process thereof. The heat exchange block structurally comprises an upper graphite block body, a middle graphite block body and a lower graphite block body which are sequentially connected from top to bottom, wherein a plurality of upper longitudinal holes are distributed in the upper graphite block body, a plurality of lower longitudinal holes are distributed in the lower graphite block body, a hollow groove is formed in the middle graphite block body, the upper longitudinal holesand the lower longitudinal holes are respectively communicated with the interior of the hollow groove, a cooling piece is arranged on the middle graphite block, and the cooling piece is communicated with the interior of the hollow groove in a circulating mode. According to the heat exchange block, waste in the hollow groove is sufficiently cooled through the cooling piece, and therefore, the cooling efficiency of the waste gas in the hollow groove is improved.
Description
Technical field: [0001] The invention relates to the technical field of production of graphite heat exchangers, in particular to a heat exchange block 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 graphite used to manufacture the heat exchanger should be impermeable. Impregnated impermeable graphite and pressed impermeable graphite are commonly used. Graphite heat exchangers are based on their The structure can be divided into three types: block hole type, shell and tube type and plate type. Among them, block hole type: assembled by several block graphite components with holes, it is mainly used for corrosion of hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid. Heat exchange of neutral medium. [0003] At present, the structure of the graphite heat exchange block is generally to open a number of longitudin...
