Abstract
The utility model discloses a kind of gas fired-boiler flue gases to take off white system, including passing through sequentially connected first valve of flue with the smoke outlet of gas fired-boiler, waste-heat recovery device, the import of second valve and chimney, the outlet of one air blower is sequentially connected third valve and the flue between the second valve and the import of chimney by air supply duct, one is equipped with one end of drainage pipeline of the 4th valve with the inlet communication of chimney and the other end is connected with header tank, present apparatus structure is simple, energy consumption is few, feature applied widely, equipment during producing and using can also be avoided to be corroded, scale formation occurs, equipment working service is at low cost.
Description
Technical field
The utility model relates to a kind of flue gases to take off white system, in particular to a kind of gas fired-boiler flue gas takes off white system.
Background technique
Since China implements green energy conservation industry, waste-heat recovery device has all been installed additional at many gas fired-boiler smoke discharging pipes.
The smoke evacuation temperature that the gas fired-boiler exhaust gas temperature of waste-heat recovery device is not installed additional at 130 DEG C -170 DEG C, after installing waste-heat recovery device additional
Degree is reduced to 50 DEG C -70 DEG C, and a large amount of vapor have been carried in smoke evacuation, especially in winter when, the vapor in flue gas is pre-chilled empty
Gas condenses in chimney outlet, forms a large amount of white cigarettes, affect the life of nearby residents, emits if not administering flue gas for a long time
Bai Xianxiang can then destroy the ecological environment on periphery.Some gas emission devices are using the method for installing heat source, some tail gas at present
Tapping equipment take carried out in the way of flue gas reheat flue gas take off it is white, both schemes will lead to system energy consumption increase and fill
Set complexity.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, a kind of less energy consumption is provided, production is can be avoided and makes
It is corroded with equipment in the process, the gas fired-boiler flue gas that scale formation occurs takes off white system.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of gas fired-boiler flue gas takes off white system, including sequentially connected by flue with the smoke outlet of gas fired-boiler
The outlet of the import of first valve, waste-heat recovery device, the second valve and chimney, an air blower passes through air supply duct
It is sequentially connected third valve and the flue between the second valve and the import of chimney, one is equipped with the 4th valve
One end of drainage pipeline is with the inlet communication of chimney and the other end is connected with header tank.
Compared with prior art, the utility model has the following beneficial effects: present apparatus structure is simple, consumes energy less, is applicable in
The wide feature of range, additionally it is possible to avoid produce and use during equipment be corroded, scale formation occur, equipment working service cost
It is low.
Detailed description of the invention
Fig. 1 is that the gas fired-boiler flue gas of the utility model takes off the structural schematic diagram of white system.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
A kind of gas fired-boiler flue gas of the utility model as shown in Figure 1 takes off white system, including the smoke evacuation with gas fired-boiler
Mouth passes through the import of flue 1 sequentially connected first valve V1, waste-heat recovery device, the second valve V2 and chimney.
The outlet of one air blower P1 is sequentially connected third valve V3 by air supply duct and is located at the second valve
Flue 1 between V2 and the import of chimney；
Piece one end for drainage pipeline 3 for being equipped with the 4th valve V4 and the inlet communication of chimney and the other end and header tank
It is connected.
It is as follows using the operating process of the present apparatus:
The first valve V1, the second valve V2 are opened, the flue gas that the gas fired-boiler generates passes through described in the entrance of smoke discharging pipe 1
Waste-heat recovery device carries out waste heat recycling in the waste-heat recovery device.
Further, third valve V3 is opened, the flue gas after the waste-heat recovery device heat exchange is sent with the air
The air that blower P1 is sent is mixed in smoke discharging pipe 1.
Further, intermittent to open the 4th valve V4, the condensed water that flue gas mixes with air generation passes through drainage pipeline 3
It is collected into the header tank, and mixed flue gas is discharged into atmosphere into chimney by smoke discharging pipe 1.
The above is only preferred embodiments of the present invention, it is noted that before not departing from the principles of the present invention
It puts, various deformation and improvement can also be made, this also should be considered as the protection scope of the utility model.
