Abstract
Disclosed is a flue heat exchanger which comprises: a cylindric shell, wherein, flanges that can be connected with a flue are arranged at both ends of the cylindric shell, and the utility model is characterized in that: at least one group of heat exchange water pipes is arranged in the cylindric shell, water inlet pipes and water outlet pipes of the heat exchange water pipes are respectively led out from walls at both ends of the cylindric shell. The heat exchange water pipes are arranged in the flue, heat energy in the high temperature gas has the heat exchange with running water therein through the heat exchange water pipes, the water flow direction in the heat exchange water pipes is opposite to the smoke exhaust direction in the flue, water in the heat exchange water pipes absorbs heat continuously and rises in temperature during flowing until being discharged through the water outlet pipes. The flue heat exchanger applies smoke gas containing heat to water heating, the heat of the high temperature gas is fully utilized, energy resources are saved, the pollution and influence to the air environment by direct high temperature gas discharge are reduced, and the environmental protection is achieved. The flue heat exchanger has advantages of simple structure, easy manufacture and installation and long service life, and is a low-cost, convenient and beneficial hot water apparatus.
Description
Technical field
The utility model relates to heat-exchange apparatus, especially a kind of chimney heat exchanger.
Background technology
In various fuel industry stoves or the boiler for domestic running, the capital produces a large amount of high-temperature flue gas, the temperature of these high-temperature flue gas generally all has hundreds of degree, is 170～180 degree as 2 tons of industrial arcola exhaust gas temperatures, and the flue-gas temperature that blast furnace is discharged through flue then can reach hundreds of degree.High-temperature flue gas is directly discharged, and is not only a kind of waste of energy, and simultaneously, the discharging of a large amount of high-temperature flue gas also can influence the atmospheric environment temperature, is unfavorable for environmental protection.
The utility model content
The purpose of this utility model is the deficiency that exists at above-mentioned condition, and a kind of chimney heat exchanger that can carry out the water heating to the heat in the high-temperature flue gas is provided.
Technical problem of the present utility model is solved by the following technical programs.
This chimney heat exchanger comprises: cylindrical outer casing, the two ends of cylindrical outer casing be provided with can with the flue flange connecting.
The characteristics of this chimney heat exchanger are: be provided with one group of heat exchanging water pipe in the cylindrical outer casing at least, heat exchanging water pipe's water inlet pipe and outlet pipe are drawn from cylindrical outer casing two ends shell wall respectively.
Technical problem of the present utility model is solved by following further technical scheme.
Described heat exchanging water pipe fixes by the support that is arranged on the cylindrical outer casing inwall.
Described heat exchanging water pipe is a spiral heat exchange tube.
Be provided with three spiral heat exchange tubes of axial symmetric arrays in the described cylindrical outer casing, back in parallel respectively, the two ends of three spiral heat exchange tubes is connected with outlet pipe with water inlet pipe.
Described heat exchanging water pipe is the tab style heat exchanging water pipe.
Described cylindrical outer casing is cylindrical shape or square tube shape or rectangular cylindrical outer casing.
The flue gas that the utility model chimney heat exchanger will contain heat is applied to the water heating.The heat exchanging water pipe is arranged in the flue, heat energy in the high-temperature flue gas carries out heat exchange by heat exchanging water pipe and the flowing water in it, water (flow) direction is opposite with the smoke evacuation flow direction in the flue in the heat exchanging water pipe, and the water in the heat exchanging water pipe is constantly heat absorption intensification in flowing, up to discharging through outlet pipe.Experimental results show that: this chimney heat exchanger is applied to 2 tons of industrial arcolas, about 170～180 degree of the temperature of smoke discharging pipe can be produced about 10,000 cubes of hot water about 60 degree every year, can save 40～50 tons in raw coal every year, thereby reduce more than 100 ton of discharging, about 60,000 cubes carbon dioxide; Consume about 100 tons about 70,000 cubes of oxygen less.If this chimney heat exchanger is applied to the flue of hundreds of degree high-temperature flue gas, then can makes to be heated water temperature 〉=100 degree, and then provide high-temperature steam for the user.
The beneficial effect that the utility model is compared with the prior art is: this chimney heat exchanger not only makes the heat of high-temperature flue gas be fully used, and has also saved the energy, has reduced pollution and the influence of the direct discharging of high-temperature flue gas to atmospheric environment, helps environmental protection.This chimney heat exchanger simple in structure is easy to processing and manufacturing and installation.Long service life.It is a kind of cheap convenient profitable hot water apparatus.
Description of drawings
Fig. 1 is the structural representation of chimney heat exchanger;
Fig. 2 is that chimney heat exchanger N-N shown in Figure 1 is to cross-sectional view.
The specific embodiment
Embodiment: can be clear that from Fig. 1 chimney heat exchanger has a cylindrical housing 11, the two ends of cylindrical housing 11 be provided with can with flue flange connecting 16.It is in parallel with water inlet pipe 13 and outlet pipe 15 respectively to be fixed with the two ends of 14, three spiral heat exchange tubes 14 of three spiral heat exchange tubes by support 12 axial symmetric arrays in the cylindrical housing 11.Water inlet pipe 13 and outlet pipe 15 are drawn from cylindrical outer casing 11 two ends shell walls respectively.
The installation and operation process of chimney heat exchanger: the boiler flue that this chimney heat exchanger will be installed blocks, utilize the flange 16 at cylindrical housing 11 two ends chimney heat exchanger to be installed between the flue that blocks, running water pipe is connected with the water inlet pipe 13 of chimney heat exchanger, and the outlet pipe 15 of chimney heat exchanger is connected with the hot water storage tank.By speed and the water yield of running water valve controllable flow through the chimney heat exchanger heat exchanging water pipe, and then control is heated the temperature of water.Water (flow) direction is opposite with the smoke evacuation flow direction in the flue in the heat exchanging water pipe, and the water in the heat exchanging water pipe is constantly heat absorption intensification in flowing, up to discharging through outlet pipe 15.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
