Description
Technical field
The utility model relates to the condensed type combustion gas water heater field, more particularly relates to a kind of heat exchanger of condensed type combustion gas water heater.
Background technology
Usually gas heater is to utilize heat exchanger to absorb the heat that combustion gas produced, pass to by the flow through cold water of heat exchanger of water inlet pipe, after the exchanger heat exchange, hot water is discharged from outlet pipe, realization adds hot water function, and the high-temperature flue gas that burning produces is strongly exhausted to the outside by blower fan.Owing to have a part of heat in the flue gas, can carry out Btu utilization like this, people set up a flue gas condensing heat-exchanger rig on the heat exchanger basis of traditional gas heater for this reason, high-temperature flue gas by the generation of combustion gas heating heat exchanger, import smoke chamber through blower fan, cold water enters condenser from water inlet pipe and absorbs high-temperature flue gas heat preheating current, cooled flue gas simultaneously, separate out condensed water and inorganic salt, condensed flue gas is discharged outdoor by the gas outlet.Through heat exchanger, hot water is discharged from the hot-water outlet pipe after exchange heat through the current of preheating, and condensed type combustion gas water heater has utilized the flue gas heat flow heated water, and heat utilization efficiency is greatly improved.And the condensed heat exchanger of prior art is to adopt finned or rib-type copper pipe heat exchanger, in actual use, the exhanst gas outlet temperature height that contains acid water steam, corrode heat exchanger fin and pipeline easily, use a period of time can cause the condenser heat exchange efficiency to reduce, situations such as corrosion of piping appear, cause water heater normally to use, in order to solve the problem of high temperature corrosion, usually at interchanger outer surface coating corrosion-inhibiting coating, but can obviously influence the heat utilization efficiency of condensing heat exchanger like this, production cost increases, and result of use promotes limited.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiency of prior art, and provide a kind ofly have compact conformation, corrosion resistance is good, heat utilization efficiency is a high condensed type combustion gas water heater heat exchanger.
The utility model is to adopt following technical solution to realize above-mentioned purpose:
A kind of novel condensing fast gas heater heat exchanger, be arranged on the burner side top of water heater, comprise cavity and inner heat exchange pipe, fume emission pipeline thereof, heat exchange pipe is connected with inlet and outlet pipe, it is characterized in that, described heat exchange pipe mainly is made of two-way or multichannel metallic coil, and this metallic coil is set up in parallel in cavity.
As further specifying of such scheme, the side perforate of described cavity is communicated with the fume emission pipeline of burner top, and two-way or multichannel metallic coil are arranged at the cavity both sides.
Described metallic coil is a stainless steel helix tube.
Described fume emission pipeline is arranged on the periphery of cavity, and the exhaust opening of fume emission pipeline is arranged on the right side of cavity.
Described inlet and outlet pipe is imported by the cavity bottom respectively and is connected with drawing with helix tube, and delivery port is arranged on the lower right side of burner.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts and be provided with the heat exchanger that the two-way stainless steel helix tube constitutes high heat utilization efficiency in condensed type combustion gas water heater, and the stainless steel cavity shell, can effectively prevent the corrosion of acid condensate water heat exchanging device, improves heat exchanger service life; And its heat exchange area is big, and radiation loss is little, and overall structure is compact, and discharge is big, thereby improves water heater overall thermal exchange efficiency, and good market value is arranged.

Description of reference numerals: burner 1, main heat exchanger 2, water inlet A1, water outlet A2 water outlet A 3, flue gas B, B1, cavity 3, stainless steel helix tube 4.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of novel condensing fast gas heater heat exchanger of the utility model, it is arranged on the main heat exchanger 2 sides top of water heater burner 1, and between the fume emission mouth, heat exchanger mainly is made of the two-way stainless steel helix tube 4 that is fixed on side by side in the cavity 3, and described cavity is a Stainless Steel Shell, and stainless steel helix tube 4 vertically is arranged on both sides in the cavity 3, be connected with the inlet and outlet pipe of shunting, realize heat exchange respectively; Described flue gas B enters Stainless Steel Shell by the blower fan of main heat exchanger 2 tops, flows toward left direction, shunts simultaneously in the both sides of helix tube 4 and carries out heat exchange, realizes efficiently heat absorption.Described inlet and outlet pipe is imported by cavity 3 bottoms respectively and is connected with drawing with helix tube 4, Inlet and outlet water by A1, A2 through the shunting after, enter in the two-way stainless steel helix tube 4 in the cavity 3, after outlet pipeline and main heat exchanger 2 heat exchange, flow out again from burner 1 lower right side water outlet A 3; Flue gas B enters cavity 1 through the perforate of closed cavity right side, is discharged by the flue outlet on cavity 3 tops again, finishes the heat exchange of pipeline.
As shown in Figure 2, in the use, combustion gas is in burner 1 burning, produce high-temperature flue gas and heat, water inlet is by condensation heat heat exchanger and flue gas heat exchange, flue-gas temperature descends, the cold water of preheating enters main heat exchanger through outlet conduit and carries out secondary heat exchange, the cold water that the produced simultaneously flue gas of heat exchange enters by fume emission pipeline and condensing heat exchanger preheating again, behind the circulation secondary heat exchange, heat absorption efficiency can reach more than 98%, hot water flows out from water outlet A 3, flue gas B1 after the heat absorption discharges from top, and institute's oxycompound is separated out in cooling in the flue gas, drains from the floss hole of cavity bottom with condensed water.
