Description

Balanced flue

Technical Field

The utility model relates to a fume emission field, in particular to balanced type flue.

Background

Most of domestic boiler combustion chambers are poor in air quality because air required by boiler combustion is extracted from the indoor through a fan, complete isolation of smoke cannot be achieved, and the smoke is not treated basically and is directly discharged, so that more NO is discharged_XThe smoke pollutes indoor air and is harmful to the health of people.

The prior balanced flue has the following defects: firstly, the smoke easily pollutes indoor air and harms the health of indoor personnel; second, generation and discharge of large amounts of NO_XThe smoke of the device pollutes the environment; and thirdly, the concentration of the oxygen delivered to the combustion chamber by the flue is not adjustable.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the not enough of prior art, provide one kind and keep apart, reduce NO with indoor air_XThe smoke discharge amount and the concentration of the conveyed oxygen are adjustable.

The utility model provides a technical scheme that above-mentioned technical problem adopted is:

the utility model provides a balanced type flue, includes outer pipeline, the cover establishes outside pipeline inside and is equipped with the open-ended interior pipeline, forms first passageway between outer pipeline and the interior pipeline, interior pipeline inner wall forms the second passageway, second passageway one end is equipped with and is used for carminative export, the second passageway other end is equipped with the first entry with first passageway intercommunication, first passageway one end is equipped with the second entry that is used for admitting air, the first passageway other end and first entry intercommunication, first passageway and second passageway still communicate through the opening. In the technical scheme, the other end of the first channel is also communicated with the combustion chamber, and outside air enters the first channel through the second inlet and enters the combustion chamber; part of smoke generated by combustion enters the second channel through the first inlet and is discharged to the outside through the outlet; another part of the flue gas generated by combustion enters the first inletThe two channels then re-enter the first channel through the opening and enter the combustion chamber with the ambient air, thereby reducing the concentration of oxygen in the combustion chamber, reducing the flame temperature, and reducing NO_XThereby greatly reducing NO_XThe smoke discharge amount is reduced, and the pollution to the environment is reduced. According to the balanced flue, air required by the combustion chamber is from outside air, and smoke generated by combustion is discharged to the outside, so that the smoke is isolated from the indoor air, the indoor air is kept clean, and the probability of indoor air pollution is reduced. The inner pipe may be fixed within the outer pipe by a bracket.

Preferably, the inner conduit is slidably provided with a baffle corresponding to the opening. Among the above technical scheme, through slide damper and adjust the open-ended size to the regulation sets up the volume that the flue gas that the burning produced gets into first passageway through the opening, thereby the staff can adjust the oxygen concentration of combustion chamber according to actual conditions, has solved the nonadjustable shortcoming of oxygen concentration that prior art's balanced type flue was carried for the combustion chamber.

Preferably, the lower edge of the opening is provided with a first sliding groove, and the baffle is slidably arranged on the first sliding groove. Among the above technical scheme, first spout accessible screwed connection establishes at open-ended lower limb portion, also can weld at open-ended lower limb portion. Slide in first spout through the baffle to adjust the opening size, thereby adjust the volume that the flue gas that sets up the burning production enters into first passageway through the opening.

Preferably, the upper edge of the opening is provided with a second sliding chute, and the baffle is slidably arranged on the first sliding chute and the second sliding chute. Among the above technical scheme, the second spout accessible screwed connection establishes at open-ended lower limb portion, also can weld at open-ended lower limb portion. Slide in first spout and second spout through the baffle to adjust the opening size, thereby adjust the volume that the flue gas that sets up the burning production gets into first passageway through the opening. First spout and second spout make the baffle establish on the interior pipeline more steadily, have reduced the probability that the baffle drops, have increased the utility model discloses the service quality of balanced type flue.

Preferably, the upper edge of the opening is further provided with a scale. Among the above technical scheme, the scale is corresponding with the opening size, and the scale is corresponding with the volume that the flue gas got into first passageway through the opening promptly, and through the scale, the staff can conveniently pass through slide damper directly perceivedly and adjust the open-ended size to adjust the volume that the flue gas that sets up the burning production got into first passageway through the opening, the staff still can conveniently take notes the opening size condition of adjusting.

Preferably, a first exhaust fan is arranged in the first channel. In the technical scheme, the first exhaust fan blows air to the inside of the balanced type flue, so that the outside air is sucked into the first channel and is conveyed to the combustion chamber. The first exhaust fan is installed on the inner wall of the inner duct such that the first exhaust fan is disposed in the first duct.

Preferably, the first exhaust fan is located on a side of the opening adjacent to the first inlet. Among the above technical scheme, first row of fan still inhales the flue gas in the second passageway through the opening first passageway to make the partial flue gas that produces of burning still get into first passageway through the opening again after getting into the second passageway through first entry, and get into the combustion chamber, thereby reduce the concentration of combustion chamber oxygen, reduce flame temperature, and reduce NO_XThereby greatly reducing NO_XAnd (4) discharging the smoke.

Preferably, a second exhaust fan is arranged in the second channel. In the above technical solution, the second exhaust fan blows air towards the outside, thereby facilitating the discharge of the flue gas in the second channel. The second exhaust fan is installed between interior pipeline outer wall and outer pipeline inner wall to the second exhaust fan is established in the second passageway.

Preferably, the second exhaust fan is located on a side of the opening adjacent to the outlet. Above technical scheme has prevented that the flue gas in the second passageway from all getting into first passageway through the opening under the effect of first exhaust fan for some flue gas in the second passageway pass through the export and discharge to the external world, and some flue gas passes through the opening and gets into first passageway.

The utility model has the advantages that:

1. the balance type flue of the utility model is isolated from the indoor air, thereby reducing the probability of the indoor air pollution caused by the flue gas and reducing the harm of the flue gas to the indoor personnel;

2. the balanced flue of the utility model reduces NO_XSmoke discharge and reduced NO_XPollution to the environment;

3. the utility model discloses a balanced type flue can adjust the oxygen concentration who carries for the combustion chamber.
