Abstract

The utility model discloses a buried two-way multi-shell-tube dry condenser, comprising a casing 11, two groups or a plurality of groups of current equalizers 1, a liquid trap 5, and a heat exchanger tube 9. The heat exchanger tube is provided with a plurality of tubes in two directions; both ends of the heat exchanger tube are respectively welded with the current equalizer and the liquid trap. The utility model decreases the density of the welding spot with convenient weld, compact structure, small size, which can decrease the space occupied by a refrigeration set.

Description

In bury two-way many group package dry condensers

One, technical field

The utility model relates to a kind of evaporation product, particularly dry condenser.

Two, technical background

Traditional shell and tube condenser is a pressure vessel, has potential safety hazard, need set up the pressure vessel administer archive, carries out annual test every year; Its tube sheet floral disc and copper pipe adopt the connected mode that expands mouthful, and it is bigger or of short duration when situation such as cutting off the water, freezing to run in the condenser difference variation, can cause leakage because of the coefficient of expansion of material is different, and maintenance difficulty is bigger; Cleaning, can only adopt chemical method during scale removal, its chemical agent has certain corrosiveness to material, influences its service life.Though I in the patent of " the package dry condenser is taken in interior slugging " (ZL01263983.4) provides a technical scheme that addresses the above problem, but scheme is unidirectional stringing owing to what take, make that the weld bond density of current equalizer and knockout is very big, be not easy to weld, if look after the volume that welding density can add large equipment again.

Three, summary of the invention

The purpose of this utility model provides a kind of anti-leak, be convenient to keep in repair and cleaning, safe in utilization, be convenient to weld, the condenser of compact conformation.

This condenser is made up of two groups or more current equalizer and liquid trap, ring flange, flow guiding disc, heat exchanger tube, housing, end cap, current equalizer, liquid trap place the housing two ends and weld with the two-port of heat exchanger tube respectively, heat exchanger tube is placed in the housing, locate by flow guiding disc, laterally the heat exchanger tube direction is opposite, it is curved that radially heat exchanger tube is done equal difference at interval, end cap is connected by flange with housing, side, housing two ends is respectively arranged with cooling water inlet and coolant outlet, current equalizer has the refrigerant vapour inlet, and liquid trap has refrigerant outlet.

The advantage of this condenser is: cold-producing medium flows in heat-exchanging tube bundle, and every index of heat-exchanging tube bundle does not all reach the standard of management type pressure vessel, so this equipment is non-management type pressure vessel, is not subjected to the management and the annual test of its national management mechanism, and is safe in utilization; Owing to use welding procedure instead, so be difficult for leakage loss under the big or flip-flop temperature regime, particularly be subjected to strong impact, vibrate and also be difficult for leakage loss at heat transfer temperature difference, in running, to cut off the water suddenly, equipment is difficult for leakage loss when freezing suddenly; The heat exchange piping can whole take out from housing, cleans, scale removal or maintenance, greatly reduces the difficulty of work; Owing to adopt two-way stringing, reduced solder joint density, be convenient to welding, and compact conformation, volume is little, can reduce refrigeration unit and take up room.

Five, specific embodiment

Fig. 5, Fig. 6, Fig. 7, Fig. 8, condenser shown in Figure 9 is by two or more circular current equalizer 1 (or boxlike current equalizers, the cast current equalizer, diaphragm capsule formula current equalizer), ring flange 7, flow guiding disc 8, U type heat exchanger tube 9, housing 11, circular liquid trap 5 (or boxlike liquid trap, the cast liquid trap, diaphragm capsule formula liquid trap), end cap 10 is formed, end cap is connected by ring flange with housing, be lined with flange gasket 12 therebetween, U type heat exchanger tube is placed in the housing, by flow guiding disc location, circular current equalizer (or boxlike current equalizer, the cast current equalizer, diaphragm capsule formula current equalizer) with circular liquid trap (or boxlike liquid trap, the cast liquid trap, diaphragm capsule formula liquid trap) adopt welding procedure to be connected in the two ends (Fig. 6) of U type heat exchanger tube respectively.U type heat exchanger tube adopts highdensity layout (Fig. 5), horizontal adjacent U type heat exchanger tube direction is opposite, radially U type heat exchanger tube is done equal difference curved (Fig. 7) at interval, condenser can design according to different needs, as the heat exchange (Fig. 8) of two group, four groups of heat exchange (Fig. 9) and the heat exchange of many groups, side, housing two ends is respectively arranged with cooling water inlet 3 and coolant outlet 6, and cooling water is entered by inlet 3 and is full of condenser, is discharged by coolant outlet 6; Cold-producing medium enters condenser by refrigerant vapour inlet 2, through circular current equalizer (or boxlike current equalizer, cast current equalizer, diaphragm capsule formula current equalizer), U type heat exchanger tube, circular liquid trap (or boxlike liquid trap, cast liquid trap, diaphragm capsule formula liquid trap), discharge 4 in the refrigerant liquid outlet.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are another embodiment of the present utility model, it is with the U type heat exchanger tube snake type heat exchanger tube (Fig. 1) that changes the outfit, adopt horizontal adjacent snake type heat exchanger tube direction opposite (Fig. 3), radially connect into two-way two groups (or many groups) heat exchange mode of snake type heat exchanger tube (Fig. 2) by little U word elbow, or adopt horizontal adjacent snake type heat exchanger tube direction identical, unidirectional many group heat exchange modes (Fig. 4) of radially many group snake type heat exchanger tubes.
