An intake tube and a delivery tube are arranged in the casing through the right end cover; a heating core is arranged between the intake tube and the delivery tube; the heat supply collection box and the heat return collection box of the heating core are respectively communicated with the intake tube and the delivery tube; a heat supply arm tube and a heat return arm tube are respectively communicated with the heat supply collection box and the heat return collection box, and the heat supply arm tube is communicated with the heat return arm tube through a heating coil. The heating coil of the utility model has good elasticity, and the casing is placed in horizontal type and does not need a large factory building so that the installation and the maintenance are convenient. The utility model is an ideal heat exchanger which has the advantages of high heat exchange efficiency, energy saving and convenient operation and does not need scale removing.

Description

Suspension-arm self-agitating horizontal coiled-pipe heat-exchanger

The utility model belongs to heat exchanger, and particularly a kind of cantilever is from disturbance coil pipe horizontal heat exchanger.

Heat exchanger of the prior art uses shell heat exchanger and spiral heat exchanger mostly, and shell-and-tube heat exchanger is applied widely, bears the pressure height, but heat-transfer effect is relatively poor, and volume ratio is huger, easily scales, difficult in maintenance, and, be difficult to accurate temperature controlling because capacity is bigger.The spiral heat exchanger compact conformation, heat-transfer intensity is higher, is difficult for dirty plug, but because the structure of spiral plate itself makes its maintenance very difficult, then have to scrap as if internal damage, so service life is lower.The patent No. is 92219187.5 combined type horizontal floating coiled pipe water-water heat exchanger, though solved the problem of above-mentioned existence, owing to be vertical, the factory building height height, though itself has elasticity coil pipe, coil pipe is produced float, strengthened heat transfer current generation local dip, and accumulation and sclerosis difficulty that coil pipe floats and can make incrustation scale, thereby slowed down the fouling of coil pipe wall, but because coil pipe unsteady little, thereby heat exchanger effectiveness is still not ideal enough, and still have the problem of incrustation scale.

The purpose of this utility model is for overcoming above-mentioned shortcoming, and a kind of heat exchange efficiency height is provided, and temperature control is accurate, and energy savings is easy to use, and a kind of cantilever that need not remove incrustation scale is from disturbance coil pipe horizontal heat exchanger.

The purpose of this utility model is achieved in that it is that existing heat exchanger is improved, with former vertical change into horizontal, housing is a horizontal positioned, left side at housing, right two ends are respectively equipped with left end cap and right end cap, and be connected as a single entity by flange, in housing, be provided with ingress pipe and delivery line by right end cap, be provided with several heating movements between ingress pipe in housing and the delivery line, heating heat supply collection case of movement and backheat collection case respectively with ingress pipe, delivery line communicates, be respectively equipped with the heat supply arm pipe and the backheat wall pipe of several unequal lengths on heat supply collection case and the backheat collection case, heat supply arm pipe communicates with backheat arm pipe by heat(ing) coil, heat(ing) coil is a multilayer, and it is little that it vertically is two, olive shape broad in the middle is arranged.Heat(ing) coil individual layer horizontal direction is 3/4ths circles.On left and right end cap, be respectively equipped with and be heated water out and be heated water inlet, above housing, be provided with the thermocouple interface successively, glass thermometer interface, air bleeding valve interface, pressure gauge connection and relief valve connection are provided with sewage draining exit and base below housing.

The utility model is owing to increased heat supply collection case, backheat collection case, heat supply arm pipe and backheat arm pipe on the heating movement between ingress pipe and the delivery line, thereby make the good springiness of heat(ing) coil own, because being heated water flows to heat(ing) coil generation effect upwards, and being produced, heat(ing) coil floats, current are produced local dip, strengthened heat transfer, and the incrustation scale in the heat(ing) coil is built up and the sclerosis difficulty, thereby has a function of antiscale and scale removal, the utility model is owing to adopting the horizontal placement of housing thereby not needing tall and big factory building, so installation and maintenance are all convenient.

Accompanying drawing is the schematic diagram and the embodiment of the utility model concrete structure.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model heating movement;

Fig. 3 is the individual layer vertical view of the heat(ing) coil in the utility model heating movement.

Below in conjunction with accompanying drawing the utility model is further elaborated:

As shown in the figure, housing 3 horizontal positioned of the present utility model, left side at housing 3, right two ends are connected with left end cap 14 and right end cap 13 by flange respectively, ingress pipe 8 and delivery line 10 are horizontally set in the housing 3 by right end cap 13, vertically be provided with several heating movements 5 between ingress pipe 8 in housing 3 and the delivery line 10, the heat supply collection case 17 and the backheat collection case 18 of heating movement 5 are connected with ingress pipe 8 and delivery line 10 respectively, vertical respectively several heat supply arm pipes 19 and the backheat arm pipe 20 of being provided with on heat supply collection case 17 and the backheat collection case 18, vertical mutually between heat supply arm pipe 19 and the backheat arm pipe 20, heat supply arm pipe 19 communicates with backheat arm pipe 20 by heat(ing) coil 16.Above housing 3, be provided with thermocouple interface 1, glass thermometer interface 2, air bleeding valve interface 4, pressure gauge connection 6 and relief valve connection 7 successively, below housing 3, be provided with sewage draining exit 15 and base 12.On left end cap 14, be provided with and be heated water out 11, on right end cap 13, be provided with and be heated water inlet 9.
