Abstract

The utility model relates to a novel spiral pipe heat exchanger, which is composed of a cylinder body, a current dividing box, a pipe plate, spiral pipes and a supporting plate. The utility model is characterized in that two partition boards arranged in the current dividing box are used for dividing the current dividing box into an A, a B and a C three chambers, and the front end of the current dividing box is provided with a steam inlet and a condensed water outlet respectively communicated with the B chamber and the A chamber; four sets of U-shaped spiral pipes are arranged in the cylinder body transversely, the end ports of the first and the second sets of spiral pipes inserted in the pipe plate are communicated with the B chamber and the C chamber, and the end ports of the third and the fourth sets of spiral pipes inserted in the pipe plate are communicated with the A chamber and the C chamber. The high-efficiency and energy-saving heat exchanger of the utility model integrated with heat exchange and condensed water recovery has compact structure, small size and convenient installation, maintenance and operation.

Description

A kind of novel spiral grooved tube heat exchanger

The utility model relates to a kind of heat exchanger, specifically a kind of novel spiral grooved tube heat exchanger.

Along with the fast development of national economy, skyscraper progressively increases, thereby the heat exchanger of architectural central heating becomes requisite heat-exchange apparatus.But traditional tubular heat exchanger is to be combined by " steam water heat exchanger " and " coagulating hydro-thermal amount recover ", so pipeline is many, and volume is big, thereby not only installs, safeguards, operates inconvenience, and the thermal efficiency is low, the cost height.Application number is 95209802.4, the applying date is on April 27th, 95, name is called " a kind of novel screwed tube heat exchanger " and has solved the problems referred to above substantially, but because three dividing plates of installing are divided into four zones in end socket, establish the condensed water entry and exit on the end socket again, thereby complex structure, increased volume, moreover only horizontal two groups of " U " type screw thread heat exchanger tubes in the housing, thereby can not fully make heat transferred be heated fluid, the thermal losses height.

The purpose of this utility model provides that a kind of to collect heat exchange and coagulate water waste heat recovery two functions be efficient, the energy-conservation spiral grooved tube heat exchanger of one.

Another purpose of the present utility model provides a kind of reasonable in design, compact conformation, volume is little, is convenient to install the heat exchanger of maintenance, operation.

The purpose of this utility model is realized by following technical scheme.

The utility model is by cylindrical shell, current divider box, tube sheet, spiral grooved tube and be latticed gripper shoe and form, and it is characterized in that:

Two dividing plates of installing are divided into A, B, three chambers of C in a, the described current divider box, and the current divider box front end is provided with steam inlet and condensation-water drain, are communicated with B chamber and A chamber in the current divider box respectively;

B, in the interior horizontal cylindrical shell of spiral grooved tube that is " U " type to outer four groups, the port of first and second two groups of spiral grooved tubes inserts tube sheet and is communicated with B chamber and C chamber in the current divider box respectively, and the port of third and fourth two groups of spiral grooved tubes inserts tube sheet and is communicated with A chamber and C chamber in the current divider box respectively.

When steam enters separating box B chamber by the steam inlet, just enter first and second two groups connection B chambers and place the interior spiral grooved tube of cylindrical shell, the be heated water outer with pipe carries out thermal conversion, part steam since the condensed water that becomes of heat release together with steam from being communicated with third and fourth the two groups spiral grooved tube heat exchanges once more that place in the cylindrical shell of C chamber, fully absorb and utilize its sensible heat, discharge by the condensation-water drain that is communicated with the A chamber at last.

The utility model has the advantages that by two dividing plates are set in current divider box, be divided into three Room, constitute four loops with three Room respectively by four groups of " U " type spiral grooved tubes that are horizontally placed in the cylindrical shell again, thereby make heat exchange area big, thereby thermal efficiency height, and with coagulate the water waste heat recovery and unite two into one.Simultaneously reasonable in design, compact conformation, volume is little, and installation, maintenance is easy to operate.

Be spiral grooved tube owing to heat exchanger tube again, so tube outer surface is less scaling, thus long service life.

Fig. 1 is the utility model structural representation.

By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.

Embodiment:

(referring to Fig. 1) installs two spacer blocks 6 in current divider box 2, be divided into A, B, three chambers of C, and current divider box 2 front ends are provided with a steam inlet 7 and a condensation-water drain 8, makes it be communicated with B chamber and A chamber in the current divider box 2 respectively.Four groups of spiral grooved tubes 4 that are " U " type are horizontally placed on water inlet 9 and the delivery port 10 that top has band temperature control auxiliary adjustment mouth 11, and be equipped with in the cylindrical shell 1 of a draining valve 12 bottom, by latticed gripper shoe 5 support fixation.The port of first and second two groups of spiral grooved tubes inserts tube sheet 3 and is communicated with B chamber and C chamber in the current divider box 2 respectively, and the port of third and fourth two groups of spiral grooved tubes inserts tube sheet 3 and is communicated with A chamber and C chamber in the current divider box 2 respectively.By flange 13 current divider box 2 and cylindrical shell 1 are linked into an integrated entity then.
