Abstract
The utility model relates to a heat-exchanger for fractional distillation, reaction and crystallization, which is composed of heat exchange tubes and a casing. The heat exchange tubes through which heat transfer medium can pass are arranged densely in a grade separation and grouping drawer type mounting means. Each chamber of the drawer type heat exchange tubes can be convenient for withdrawing. The utility model which has the advantages of uniform heat exchange tube arrangement, high heat transfer efficiency, non thermal stress, convenient installation, convenient maintenance, and long service life. The utility model can be used as a heat exchanger for cooling or heating in the process of fractional distillation, reaction, crystallization, etc.
Description
The utility model relates to a kind of heat-exchanger rig that is used for fractionation, reaction, crystal chemistry process.
The fractionator that crude benzol workshop section adopts between coke-oven plant's recovery vehicle is generally fixed tube sheet type now, square tube sheet is welded on the rectangle housing, and the heat exchanger tube expanded joint leads to cold oil, cooling water in the heat exchanger tube on tube sheet, the logical outward coke oven destructive distillation gas of cooling tube makes it fractionate out naphthalene and crude benzol.Because temperature is low in the pipe, case temperature is high, there is bigger thermal (temperature difference) stress between housing and the pipe, cause easily that heat exchanger tube pulls, leakage of oil, drainage, both reduced production efficiency, influence product quality again.For prevent to pull, leakage of oil, then the cold oil oil pressure can not improve, flow velocity can not be accelerated, and causes heat transfer efficiency low, influences production capacity.In addition, after heat exchanger tube pulled, changing needed integral replacing, and difficulty is changed in not only lifting, and influence is produced.
The purpose of this utility model is the problem that exists according to the fixed tube sheet type fractionator, is intended to design a kind of novel fractionation, reaction, crystallization heat-exchanger rig, the no thermal (temperature difference) stress of this device, heat transfer efficiency height, long service life, and the installation maintenance is all very convenient.
The purpose of this utility model realizes in the following manner, a kind of fractionation, reaction, crystallization heat-exchanger rig, by heat exchanger tube 1,4, housing 3 constitutes, be furnished with have on the heat exchange bobbin carriage of heat exchanger tube for heat transferring medium into and out of mouth, have on the housing for fractionation, reaction, crystallization gas, liquid into and out of mouth, the heat exchanger tube 4 of logical heat transferring medium by the installation of grouping drawer type, is made up of for 6 the casees 2-6 drawer type heat exchanger tube for every group housing 3 in.The heat exchange bobbin carriage reaches hull outside, outside it case lid 7 is arranged, and has communicating pipes 5 to be communicated with between each heat exchange bobbin carriage.Have under each heat exchange bobbin carriage for the convenient slide rail of extracting out of heat exchange bobbin carriage.All have cold oil to import and export f, g on each heat exchange bobbin carriage, dress heat exchanger tube within it adopts the tube bank of U type, is crossings on different level and arranges.
The utility model content is described in detail in detail with reference to the accompanying drawings.

The A-A cut-away view of Fig. 2 Fig. 1
Fig. 3 is positioned at the heat exchange bobbin carriage heat-exchanging tube bundle crossings on different level layout drawing in framework centre position
The B-B view of Fig. 4 Fig. 3
With reference to accompanying drawing, the heat exchanger tube 4 of the logical heat transferring medium of the utility model by the installation of grouping drawer type, is made up of 2-6 heat exchange bobbin carriage for every group housing 3 in, under each heat exchange bobbin carriage slide rail is arranged, and can conveniently extract easy access and replacing out.Heat exchanger tube adopts the U-shaped tube bank, directly is not welded on the housing, has avoided the thermal (temperature difference) stress between tube bank and tube sheet.Heat exchanger tube adopts the crossings on different level dense arrangement stringing shown in Fig. 3,4, and stringing is even, and the heat transfer area in the unit volume is big, the heat transfer efficiency height.
The utility model once between coke-oven plant's recovery vehicle crude benzol workshop section on probation, respond well, oven gas is entered by bottom a mouth, in tower, rise, through bottom cold oil heat exchange bobbin carriage 6, by the discharge of outlet c, d, e, the higher oven gas of benzene content is discharged by outlet b successively for 2 coolings of top cooling water heat exchange bobbin carriage, the thick naphthalene that condensation goes out.Cold oil enters the heat exchange bobbin carriage by f1, f2, f3, f4, f5, f6 inlet respectively, exports discharge by g1, g2, g3, g4, g5, g6 respectively again.
The heat exchanger tube of the logical heat transferring medium of the utility model adopts the tube bank of U type, crossings on different level dense arrangement stringing, and grouping drawer type mounting means, stringing is even, the heat transfer efficiency height, no thermal (temperature difference) stress is convenient to install and maintenance long service life.
The utility model can be used as the cooling of processes such as fractionation, reaction, crystallization or adds heat exchanger.
Claims (1)
1, a kind of fractionation, reaction, the crystallization heat-exchanger rig, by heat exchanger tube 1,4, housing 3 constitutes, be furnished with on the heat exchange bobbin carriage of heat exchanger tube and have for heat transferring medium, the mouth that goes out, have on the housing for fractionation, reaction, crystallization gas, liquid advances, the mouth that goes out, the heat exchanger tube 4 that it is characterized in that logical heat transferring medium is installed by the grouping drawer type in housing 3, form by 2-6 drawer type heat exchange bobbin carriage 6 for every group, the heat exchange bobbin carriage reaches hull outside, outside it case lid 7 is arranged, have communicating pipes 5 to be communicated with between each heat exchange bobbin carriage, have under each heat exchange bobbin carriage for the convenient slide rail of extracting out of heat exchange bobbin carriage, the heat exchanger tube that is contained in the heat exchange bobbin carriage adopts the tube bank of U type, is crossings on different level and arranges.
