Summary of the invention

The utility model is exactly a kind of spiral single tube condensing heat exchanger that provides in order to solve above-mentioned technical deficiency, the single corrugated stainless steel tubing that adopts spiral distribution is as heat exchange element, not only simple in structure, handling ease, and each component distribution is reasonable, heat exchange efficiency is high.

The utility model is to adopt following technical scheme to realize above-mentioned purpose: a kind of spiral single tube condensing heat exchanger, comprise shell, be located at advancing mouth and exhaust opening, be located at the heat exchanger tube in the shell on the shell, it is characterized in that: this heat exchanger tube be single corrugated stainless steel tubing and in the enclosure portion's spiral distribute.

As further specifying of such scheme, described heat exchanger tube is scattered in tubular structure along the outer casing inner wall spiral.

Described heat exchanger tube top is provided with the flow deflector of cone barrel, and this flow deflector is located at the exhaust opening below, and the vertex of a cone of this flow deflector points to the heat exchanger tube bottom along the axis of tubular heat exchanger tube, and exhaust opening is pointed in the bottom of this flow deflector.

Described heat exchanger tube spiral in the enclosure is scattered in the awl tubular structure, and the bottom of this awl barrel structure is located at into mouth place, and the top is located at the exhaust opening place.

Described heat exchanger tube is provided with water inlet and delivery port, and this water inlet is located at the initiating terminal of shell inner bottom part for the heat exchanger tube helical structure, and this delivery port is located at the shell inner top by the heat exchanger tube helical structure clearing end extends to outer casing bottom and constitutes.

Described shell is circular or square tubular structure, and exhaust opening is located at cover top portion, advances mouth and is located at the shell lower end side.

Described outer casing bottom also is provided with condensation-water drain.

The beneficial effect that the utility model adopts above technical scheme to reach is:

1. the utility model adopts helical arrangement to become the single corrugated stainless steel tubing of cylinder or awl tube as heat exchange element, high-temperature flue gas enters from condensing heat exchanger cavity bottom again and discharges from the top, contact area is big, heat exchange efficiency is high, but also can flow deflector optionally be set at the exhaust opening place on cylindric heat exchanger top, the peripherad bellows of flue gas is flowed upwards discharges again, increase the time of staying of flue gas in heat exchanger, further improved heat exchange efficiency.

2. heat exchange element of the present utility model is the bellows that single spiral distributes, and manufacture craft is simple, and installation and maintenance is also more convenient, and this bellows is stainless steel, and corrosion resistance is strong, do not need to establish in addition corrosion-resistant finishes, so cost is lower.

3. the cold water of the utility model heat exchange element is before upwards is transported to the heat exchanger top by straight tube from the heat exchanger bottom, drop to the bottom from the top spiral again, again from bottom output, the heat-exchange time of whole process cold water and flue gas is longer at last, has therefore improved heat exchange efficiency greatly.
