Description
Technical field
The present invention relates to a kind of graphite heat exchanger, be specifically related to a kind of composite graphite heat exchanger.
Background technology
Graphite heat exchanger is the heat exchanger that heat-transferring assembly graphite is made.The graphite manufacturing heat exchanger should have impermeability, conventional dipping class impermeable graphite and die mould impermeable graphite.Graphite heat exchanger can be divided into block Kong Shi ﹑ shell-and-tube and board-like 3 types by its structure.Block cellular type: the blocky graphite assembling components with holes by several forms.Shell-and-tube: shell-and-tube heat exchanger occupies critical role in graphite heat exchanger, is divided into again fixed and floating head type two kinds by structure.Board-like: plate type heat exchanger graphite cake bonding is made.In addition, Chen Jin Shi ﹑ fountain and bushing type etc. is also had.Graphite heat exchanger corrosion resistance and good, heat-transfer area is less scaling, and heat transfer property is good.But the easy embrittlement of graphite, bending resistance and tensile strength low, thus can only be used for low pressure, even if the block cavernous structure that bearing capacity is best, its operating pressure is generally also only 0.3 ~ 0.5 MPa.The cost of graphite heat exchanger is high, and volume is large, uses few.It is mainly used in the heat exchange of the Korrosionsmediums such as hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid, as being used as the condenser etc. of acetic acid and acetic anhydride.
In order to save stainless steel and valuable nonferrous materials, graphite heat exchanger is widely used for the Korrosionsmediums such as process hydrochloric acid, sulfuric acid, acetic acid and phosphoric acid.Current graphite heat exchanger substantially divides two large class shell and tube and block cellular types structure.Tube-type graphite heat exchanger structure is simple, graphite material utilization rate is high, can be made into the equipment of larger heat transfer area, unit heat exchange area cost is lower than other version, but heat transfer efficiency is not as block cellular type, allow the pressure that uses lower, generally all not higher than 1Mpa, should not have intense impact, vibration and easily produce water hammer occasion under use.Block hole-type graphite heat exchanger table structure is firm, and having higher heat transfer system can improve operating pressure, is applicable to the occasion of thermal shock or vibration, but fluid resistance is comparatively large, and heat transfer area is little.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
