The utility model is characterized in that the cylinder body is divided into an upper cylinder body and a lower cylinder body, a middle tube plate is arranged between the upper cylinder body and the lower cylinder body, and the graphite tube bundle in the upper cylinder body is fixed between an upper tube plate and the middle tube plate; the upper tube plate is connected with the upper sealing head, and the upper cylinder body is provided with a cooling water secondary inlet and a cooling water secondary outlet; the graphite tube bundle in the lower cylinder body is fixed between the middle tube plate and a lower tube plate which is connected with the lower sealing head; the lower cylinder body is provided with a cooling water primary inlet and a cooling water primary outlet; the upper sealing head is connected with a material inlet, and the lower sealing head is connected with a material outlet. The major structure of the utility model is divided into two big parts, and the upper cylinder body and the lower cylinder body form two heat exchanging bodies to form a heat exchanging state with two poles so as to greatly increase the heat transferring efficiency of the whole equipment.
Description
Technical field
The utility model relates to a kind of efficient heat transfer graphite heat-exchange apparatus.
Background technology
Existing tube-type graphite system heat transmission equipment comprises cylindrical shell, graphite tube bank, tube sheet and upper cover, low head, has cooling water inlet and coolant outlet on the cylindrical shell.Cylindrical shell is an overall structure, and the graphite tube bank is installed between upper cover and the low head, is Integratively heat exchange state.The problem of its existence is; heat exchange efficiency is not high; thereby the glued position of heat exchanger tube tension that produces owing to the heat-exchanging tube bundle difference in elongation when the higher situation of temperature and tube sheet can not get effective protection; thereby produce shearing force and destroy problem; its serviceability temperature, working pressure all are restricted, and generally are controlled at 120～130 ℃.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of efficient heat transfer graphite heat-exchange apparatus, heat transfer efficiency height, heat resisting and pressure resisting performance height.
The utility model heat exchanger of graphite, comprise cylindrical shell, the graphite tube bank, upper cover, low head, have cooling water inlet and coolant outlet on the cylindrical shell, it is characterized in that cylindrical shell is divided into upper shell and lower shell, between upper shell and the lower shell sagging plate is set, graphite tube bank in the upper shell is fixed between upper perforated plate and the sagging plate, upper perforated plate connects upper cover, have the outlet of import of cooling water secondary and cooling water secondary on the upper shell, graphite tube bank in the lower shell is fixed between sagging plate and the lower perforated plate, lower perforated plate connects low head, having an import of cooling water and cooling water on the lower shell once exports, upper cover connects material inlet, and low head connects material outlet.
The utility model agent structure is divided into the two large divisions, and upper shell and lower shell form two heat exchange bodies, forms the two poles of the earth heat exchange state, the heat transfer efficiency of integral device is increased substantially, its mean value 800～1000W/m
2.k.Compare " the graphite inhibition and generation construction equipment " published in Chemical Industry Press's industrial equipment and information engineering publishing centre middle standard tube-type graphite heat exchanger at gas heat-transfer coefficient numerical value 348.9～174.45W/m
2.k much higher.
Sagging plate places in the cylindrical shell and is effectively protected, and has prolonged the service life of tube sheet and integral device greatly.
The last metal cover board of upper cover and connection, pull bar, spring, material inlet frame mode and low head are identical with original tube-type graphite system heat transmission equipment with the frame mode of lower cover, material outlet.
Advantage of the present utility model:
Equipment heat transfer efficiency height.Be used in especially under acid, alkali, salt class I liquid I, gas and gas-liquid mixture cooling, the condensation process state.Serviceability temperature, working pressure height, chemical stability is good, can be widely used in chemical engineering industry.Alternative stainless steel of while and other valuable non-ferrous metal.Maintenance, easy maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 4 times graphite of 1 lower cover 2 low heads, 3 lower perforated plates are restrained 5 lower shells, 6 bearings, 7 cooling waters and are once exported on 8 cooling water secondary imports, 9 sagging plates, 10 upper shells 11 graphite and restrain 12 cooling water secondaries and export import 19 material outlets of 13 upper covers, 14 material inlets, 15 upper cover plates, 16 spring compression means, 17 upper perforated plates, 18 cooling waters
The specific embodiment
As Fig. 1, integral device comprises upper shell 10 and lower shell 5, between upper shell 10 and the lower shell 5 sagging plate 9 is set, last graphite tube bank 11 in the upper shell is fixed between upper perforated plate 17 and the sagging plate 9, upper perforated plate 17 connects upper cover 13, upper cover 13 constitutes sealing with upper cover plate 15, spring compression means 16, has cooling water secondary import 8 and cooling water secondary outlet 12 on the upper shell.Following graphite tube bank 4 in the lower shell is fixed between sagging plate 9 and the lower perforated plate 3, and lower perforated plate 3 connects low head 2, and low head 2 constitutes sealing with lower cover 1, has an import 18 of cooling water and cooling water on the lower shell and once exports 7.Upper cover connects material inlet 14, and low head connects material outlet 19.
The last graphite tube bank 11 of corrosivity chemical material in equipment material inlet 14 access arrangement upper shells 10 conducted heat by the graphite tube wall with tube bank outer cooling aqueous fluid (being entered by cooling water secondary import 8), formation one-level heat exchange body; Material is after one-level cools, and the sagging plate 9 of flowing through enters down graphite tube bank 4, conducts heat by the graphite tube wall with tube bank outer cooling aqueous fluid (being entered by an import 18 of cooling water), forms secondary heat exchange body.Because two-stage heat exchange body cooling water inlet temperature is all lower, the temperature gradient difference of formation is bigger, and this heat transfer for equipment is great motive force, and heat transfer efficiency is provided greatly.
Technical indicator:
Design pressure: 0.50MPa
Design temperature :-20～180 ℃.
