The utility model content:
The purpose of this utility model is according to the deficiencies in the prior art part, provides a kind of built-in condensation heat to reclaim vacuum hot water boiler, improves the thermal efficiency of boiler.
Technology solution of the present utility model is as follows:
A kind of built-in condensation heat reclaims vacuum hot water boiler, comprise boiler, the vacuum boiler heat exchanger is installed in the described boiler, also comprise a condensation recover, there is flue gas heat recovery device collecting chamber described condensation recover upper end, there is flue gas heat recovery device water-dividing chamber the lower end, between described flue gas heat recovery device collecting chamber and described flue gas heat recovery device water-dividing chamber, there is flue gas to pass through the chamber, this flue gas has gas approach and exhanst gas outlet that is used to discharge flue gas that fume collecting chamber is communicated with behind the boiler of and boiler by the chamber, described flue gas heat recovery device collecting chamber is communicated with by intermediate connection tube and described vacuum boiler heat exchanger, at described flue gas by the indoor flue gas condensing heat-transfer pipe that described flue gas heat recovery device collecting chamber and described flue gas heat recovery device water-dividing chamber are communicated with that is equipped with.
Described a kind of built-in condensation heat reclaims vacuum hot water boiler, and the bottom of described flue gas heat recovery device water-dividing chamber is equipped with the boiler water inlet pipe that communicates with it.
Described a kind of built-in condensation heat reclaims vacuum hot water boiler, and described boiler water inlet pipe is communicated with by bypass pipe and described intermediate connection tube, and the by-passing valve of its open and close of control is installed on the described bypass pipe.
Described a kind of built-in condensation heat reclaims vacuum hot water boiler, and being equipped with on the described condensation recover with described has flue gas to communicate, be used for discharging the condensation delivery pipe of flue gas by indoor condensed water by the chamber.
Described a kind of built-in condensation heat reclaims vacuum hot water boiler, and described vacuum boiler heat exchanger is made of a plurality of vacuum boiler heat exchanger tubes.
The utility model beneficial effect is:
Of the present utility model with condensation recover and the integrated making of boiler, and utilize the preheating in the flue gas heat recovery device of system hypothermia backwater, not needing other recirculated water cooling flue gas, system is simple, and recuperation of heat is effective, and user installation is easy to use.Behind the high-temperature flue gas process condensation recover of back fume collecting chamber discharge, reduce exhaust gas temperature on the one hand, discharge fume afterheat.On the other hand steam a large amount of in the flue gas is condensed into water, emit the condensation latent heat of vaporization, the system hypothermia backwater condensing heat exchanger of flowing through absorbs the flue gas liberated heat, enters the vacuum boiler heat exchanger after the preheating, and the thermal efficiency of boiler is improved more than the 8-10%.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is this novel structural representation.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1; A kind of built-in condensation heat reclaims vacuum hot water boiler, comprise boiler 13, vacuum boiler heat exchanger 2 is installed in the described boiler, also comprise a condensation recover 14, there is flue gas heat recovery device collecting chamber 4 described condensation recover upper end, there is flue gas heat recovery device water-dividing chamber 8 lower end, between described flue gas heat recovery device collecting chamber 4 and described flue gas heat recovery device water-dividing chamber 8, there is flue gas to pass through chamber 15, this flue gas has gas approach 16 and exhanst gas outlet 6 that is used to discharge flue gas that fume collecting chamber 12 is communicated with behind the boiler of and boiler by the chamber, described flue gas heat recovery device collecting chamber 4 is communicated with intermediate connection tube and flue gas heat recovery device collecting chamber by intermediate connection tube 3 and described vacuum boiler heat exchanger, the vacuum boiler heat exchanger can adopt welding, modes such as bolt connection connect; The other end of vacuum boiler heat exchanger and the boiler discharging tube 1 that is installed on the boiler are communicated with, at described flue gas by the indoor flue gas condensing heat-transfer pipe 5 that described flue gas heat recovery device collecting chamber 4 and described flue gas heat recovery device water-dividing chamber 8 are communicated with that is equipped with.The flue gas condensing heat-transfer pipe is a plurality of, can be connected with flue gas heat recovery device water-dividing chamber, flue gas heat recovery device collecting chamber by the mode two ends of welding.
The bottom of described flue gas heat recovery device water-dividing chamber 8 is equipped with the boiler water inlet pipe 9 that communicates with it.
