Abstract
The utility model provides a round block type graphite heat exchanger resistant to high pressure and easy to clean. A-level fine particle graphite materials resistant to high pressure are used as graphite raw materials. Two sizes of heat exchange blocks which are sealed together with one above and the other below are used as heat exchange blocks of equipment. Two circles of different sizes of expanded polytetrafluoroethylene gasket dual seal are used as seal between the heat exchange blocks, and four waterlines are processed with a waterline knife on each seal surface. Nominal diameter of hole channels of the upper heat exchange block and the lower heat exchange block is equal to the hole diameter of inlet and outlet ports of an upper seal head and a lower seal head, and the hole channels are processed into an upper through hole and a lower through hole. A material medium inlet and outlet port is designed to be of a wide mouth structure. High-reliability flexible graphite spiralwound gasket is used for sealing for the sealing gasket at the position of a flange of a lower shell body. A fluororubber O-type ring seal is used for sealing between pressure flanges of an upper shell body. A compression spring is designed on a flange of the upper seal head. The pressure flange of the upper shell body, the flange of the upper seal head and the compression spring are connected through bolts. The round block type graphite heat exchanger resistant to high pressure and easy to clean can be used in processes of waste acid concentration, easily-crystallized material heating, diaphragm type evaporation and the like.
Description
Technical field
The utility model relates to chemical field, relates in particular to a kind of high pressure resistant, easy cleaning
The graphite block heat exchanger graphite heat exchanger.
Background technology
It is less than normal that the material medium of the graphite block heat exchanger graphite heat exchanger of chemical standard series is imported and exported inside nominal diameter; Some material that concentrate to be prone to crystallization is prone to cause in the hole under heating condition and stops up, and therefore be not suitable for technical process such as the heating that concentrates the easily-crystallized stock medium, film-type evaporation, and crystal is prone to attached on the graphite hole wall; Not only influence the heat exchange effect; And when cleaning, less than normal because of importing and exporting, heat transfer block periphery duct is often cleaned unclean; Carry out monolithic again after needing equipment to disintegrate and clean, program is more loaded down with trivial details and influence the use of equipment; Leave the gap between the standard device heat transfer block; The material medium is not continuous moving upward through longitudinal holes the time, causes equipment as the reboiler purposes time; Produced not the interior film-type evaporation of tubulation of picture tube-type graphite heat exchanger; The relative tubular heat exchanger of overall heat-transfer coefficient is less than normal, but tube-type graphite heat exchanger is on the low side because of intensity under the graphite-pipe high temperature, has influenced its scope of application again;
The utility model content
The utility model provides a kind of high pressure resistant, easy graphite block heat exchanger graphite heat exchanger that cleans, and its design is: the heat transfer block upper-lower seal of two kinds of specifications of heat transfer block employing of equipment together; The varicosity Tetrafluoro spacer double sealing of two kinds of different-thickness is adopted in sealing between heat transfer block, has 4 waterlines on the per pass sealing surface; The duct inside nominal diameter of heat exchanger and last low head flow hole footpath quite is last lower through-hole up and down; The material medium is imported and exported and is the wide-mouth structure; Lower case flange place used for sealing gasket soft graphite seals after twining again; Adopt the sealing of fluorubber o type circle between the upper body differential; Have the compression spring on the upper cover differential, upper body differential, upper cover differential and compression spring are coupled together with bolt.
In sum; The beneficial effect of the utility model is: the material medium import and export inside nominal diameter that has overcome chemical standard graphite block heat exchanger graphite heat exchanger is less than normal; Be not suitable for technical process such as the heating that concentrates the easily-crystallized stock medium, film-type evaporation; And crystal is prone to influence the heat exchange effect attached on the graphite hole wall, is difficult to clean up; As the reboiler purposes time, produced not the interior film-type evaporation of tubulation of picture tube-type graphite heat exchanger, but tube-type graphite heat exchanger is on the low side because of intensity under the graphite-pipe high temperature, has influenced the shortcoming of its scope of application again; The utility model is based on above-mentioned shortcoming, and the graphite block heat exchanger graphite heat exchanger high pressure resistant, that be prone to clean of design has the structural strength height, has remedied the deficiency of tube-type graphite heat exchanger just, can be used for easily-crystallized stock again, is a kind of comparatively ideal graphite heat exchanger.
Description of drawings
Fig. 1 is this high pressure resistant, as to be prone to the graphite block heat exchanger graphite heat exchanger of cleaning structural representation of expression
The specific embodiment
As shown in Figure 1, the critical piece of equipment is: 1 is low head, and 2 is lower flange, and 3 is gasket seal, and 4 is shell flange, and 5,8 is heat transfer block; 6 is housing, and 7 is pad between heat transfer block, and 9 is bearing, and 10 is upper cover, and 11 is that housing differential, 13 is differential; 12 are sealing O type circle, and 14 is bolt, and 15 are the compression spring, and 16 is the upper cover flange, and 17 is exhaust outlet; 18 is steam inlet, and 19 is discharging hole, and 20 is condensation-water drain, and 21 is material outlet, and 22 is material inlet;
The utility model is on the basis of the graphite block heat exchanger graphite heat exchanger of standard, to improve, and technical scheme is:
According to prior standard graphite block heat exchanger graphite heat exchanger; Heat transfer block and end socket are all used A level machining graphite; And adopt warm charing heat treatment in high vacuum, high-pressure impregnation phenol-formaldehyde resin modified and 240～260 ℃, improve degree and corrosion-resistant, high temperature resistant, the high voltage performance of graphite parts; The heat transfer block of equipment is changed to the heat transfer block of two kinds of specifications; Single plant the specification heat transfer block if insufficient height, can adopt material such as resin that several of same specification are bonded together, the heat transfer block of two kinds of different sizes with two enclose different sizes varicosity Tetrafluoro spacer double sealing; Process 4 waterlines with the waterline cutter on the per pass sealing surface; Strengthen sealing surface, reduce interblock gap, make that the interblock sealing is tighter; Adopt deep hole drilling machine to be punched in vertical hole in the duct of heat transfer block up and down, be processed into lower through-hole, and inside nominal diameter is directly suitable with last low head flow hole; The monolithic orifice throat length can reach more than the 1800mm; This method reduces heat transfer block quantity, creates long vertical passage simulation film-type evaporation, only needs during cleaning to be full of the logical small amount of steam of weak solution shell side with giant flushing longitudinal holes or longitudinal holes; Pump is played circulation, can accomplish fast and clean material medium crystallization and foulant; The material medium is imported and exported and is designed to the wide-mouth structure, and the equipment that makes can be used for technologies such as spent acid concentrates, easily-crystallized stock heating, film-type evaporation; The lower case flange place high soft graphite spirotallic gasket of used for sealing gasket reliability seals, and improves the high temperature strength of pad; Adopt the sealing of fluorubber o type circle between its upper side differential, guarantee the reliability and the long-life of shell side sealing; Design compression spring on the upper cover flange couples together upper body differential, upper cover flange and compression spring with bolt, can when expanding with heat and contract with cold, seal by pretension;
