Summary of the invention
The purpose of this utility model is the phenomenon for boiler exhaust gas pipe UTILIZATION OF VESIDUAL HEAT IN, provides a kind of reasonable in design, the heat transfer structure of the boiler chimney heat utilization that hot handing-over rate is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of heat transfer structure of boiler chimney heat utilization, it is characterized in that comprising chimney breast, wrap in the outer field waterpipe of chimney breast, some the heat exchanger fins identical with walking cigarette direction are provided with in described chimney breast, heat exchanger fin is hollow-core construction, and the outlet of heat exchanger fin hollow-core construction communicates with waterpipe.To have an appointment in the fume emission process of boiler the temperature of 150 DEG C, the technical program carries out heat exchange design for boiler exhaust gas system especially, heat exchanger fin is stretched into chimney breast inside, and can arrange the fin having more heat exchange effect on surface, all heat exchanger fins are all between water inlet pipe and outlet pipe.This case can in waterpipe set temperature meter, and at water inlet pipe and outlet pipe position, by-pass valve control is installed, carries out again changing the water in waterpipe after abundant heat exchange.
As preferably, described waterpipe bottom is provided with water inlet pipe, and top is provided with outlet pipe.Length and the highest segment length of chimney breast temperature of waterpipe match.
As preferably, some described heat exchanger fins are arranged along chimney breast even circumferential.
As preferably, described heat exchanger fin is flat hollow structure, and along walking the S-shaped curve-like in cigarette direction.Heat exchanger fin does not produce resistance, favourable smoke evacuation.
As preferably, the part that described heat exchanger fin is positioned at chimney breast is up-small and down-big trapezium structure.Reduce the resistance to water-flow in waterpipe, improve heat transfer effect.
As preferably, described outlet pipe is connected with attemperater, and attemperater communicates with boiler.In the boiler hyperactivity of fire phase, the water after heat exchange is stored, and can the water circulation heating in attemperater.
As preferably, described heat exchanger fin outer surface is provided with fin.
As preferably, the width that described heat exchanger fin is positioned at chimney breast is less than or equal to the radius of chimney breast.
Effective effect of the present utility model is: walk cigarette smoke evacuation route along it, utilize hollow heat exchanger fin diversion to enter chimney breast, and make rate of heat exchange reach best, make full use of waste heat of chimney, energy-saving effect is obvious.

In figure: 1. waterpipe, 2. heat exchanger fin, 3. water inlet pipe, 4. outlet pipe, 5. chimney breast.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the heat transfer structure of a kind of boiler chimney heat utilization of the present embodiment, it is the design carrying out waterpipe 1 at chimney breast 5 skin, in order to improve heat transfer effect, in chimney breast 5, the more than one piece heat exchanger fin 2 identical with walking cigarette direction is set, same cross-section, heat exchanger fin 2 arranges 3 along chimney breast 5 even circumferential, as shown in Figure 2.
Heat exchanger fin 2 is flattened tubular configuration, and the hollow-core construction outlet of heat exchanger fin 2 is positioned at waterpipe 1 tube wall position and communicates with waterpipe.Waterpipe 1 is also water heat exchange place, and bottom connects water inlet pipe 3, and top sets out water pipe 4, and valve is equipped with respectively in water inlet pipe 3 and outlet pipe 4 position.
Heat exchanger fin 2 length direction can be pressed sigmoid curve shape and make, and as a kind of embodiment, this structure not only increases heat exchange area, plays simultaneously and draws cigarette effect.
The part that heat exchanger fin 2 is positioned at chimney breast 5 can design as a kind of embodiment by up-small and down-big trapezium structure, and this structure mainly useful for reduces water flow resistance.
