Abstract
The utility model relates to a recycling system of boiler exhaust gas. The recycling system of the boiler exhaust gas is characterized by comprising a row-fixing flash vessel (1), a demineralized water tank (2), a first demineralized water heater (3) and a second demineralized water heater (4), wherein the row-fixing flash vessel (1) is in connection with a row-fixing mother pipe (1.1). The row-fixing flash vessel (1) is connected with an inlet of a hot medium of the first demineralized water heater (3) through a pipeline. An outlet of the hot medium of the first demineralized water heater (3) is connected with an inlet of the hot medium of the second demineralized water heater (4). The demineralized water tank (2) is respectively connected with an inlet of a cold medium of the first demineralized water heater (3) and an inlet of the cold medium of the second demineralized water heater (4) through the pipeline. The recycling system of the boiler exhaust gas is added with the demineralized water tank and is internally provided with a heating coil, and therefore when exhaust gas is discharged, the demineralized water can be heated, and initial temperature can be increased by 10- 15 DEG C in average. Then the recycling system of the boiler exhaust gas can be used as a deaerator for feed-water make up, and therefore wastes are effectively changed into wealth. The recycling system of the boiler exhaust gas is not only energy-saving but also environment-friendly.
Description
Technical field
The utility model relates to a kind of reclaiming system of boiler waste gas, can the waste gas of boiler emission effectively be utilized.
Background technology
Can produce many waste gas during boiler work, and every boiler has 2% necessary discharge amount of exhaust gas, these waste gas directly are disposed to trench in the past, yet have not only caused a large amount of energy wastes also to bring thermal pollution like this.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can save the energy, turns waste into wealth, and avoids the reclaiming system of the boiler waste gas of thermal pollution.
The purpose of this utility model is achieved in that
The reclaiming system of the utility model boiler waste gas, comprise and decide row's flash vessel, sweet-water tank, the first demineralized water heater and the second demineralized water heater, described surely row is connected to the female pipe of fixed row on the flash vessel, the described flash vessel of surely arranging links to each other by the thermal medium import of pipeline with the first demineralized water heater, the thermal medium outlet of the first demineralized water heater links to each other with the thermal medium import of the second demineralized water heater, and described sweet-water tank links to each other with the cold medium import of the first demineralized water heater, the second demineralized water heater respectively by pipeline.
The reclaiming system of the utility model boiler waste gas has the following advantages:
The reclaiming system of the utility model boiler waste gas increases the demineralized water water tank, and built-in heat(ing) coil can heat demineralized water during toxic emission, on average can improve initial temperature 10-15 ℃, then as the oxygen-eliminating device make-up water, effectively turns waste into wealth, not only energy-conservation but also environmental protection.
Description of drawings
Fig. 1 is the structural representation of the reclaiming system of the utility model boiler waste gas.
Among the figure: surely arrange flash vessel 1, the female pipe 1.1 of fixed row, sweet-water tank 2, the first demineralized water heater 3, the second demineralized water heater 4.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of reclaiming system of boiler waste gas, comprise and decide row's flash vessel 1, sweet-water tank 2, the first demineralized water heater 3 and the second demineralized water heater 4, described surely row is connected to the waste heat waste gas that the female pipe 1.1 of fixed row is used for passing into the boiler generation on the flash vessel 1, the described flash vessel 1 of surely arranging links to each other by the thermal medium import of pipeline with the first demineralized water heater 3, the outlet of the thermal medium of the first demineralized water heater 3 links to each other with the thermal medium import of the second demineralized water heater 4, described sweet-water tank 2 by pipeline respectively with the first demineralized water heater 3, the cold medium import of the second demineralized water heater 4 links to each other.
The waste gas that produces of boiler just can heat demineralized water like this, can improve demineralized water 10-15 ℃, and the demineralized water after the heating is got in the oxygen-eliminating device as make-up water by water pump, thereby turns waste into wealth, not only energy-conservation but also environmental protection.
Claims (1)
1. the reclaiming system of a boiler waste gas, it is characterized in that: it comprises decides row's flash vessel (1), sweet-water tank (2), the first demineralized water heater (3) and the second demineralized water heater (4), described surely row is connected to the female pipe of fixed row (1.1) on the flash vessel (1), the described flash vessel (1) of surely arranging links to each other by the thermal medium import of pipeline with the first demineralized water heater (3), the outlet of the thermal medium of the first demineralized water heater (3) links to each other with the thermal medium import of the second demineralized water heater (4), described sweet-water tank (2) by pipeline respectively with the first demineralized water heater (3), the cold medium import of the second demineralized water heater (4) links to each other.
