CN207763009U - Self-suction type high-rise public flue - Google Patents

Abstract

The utility model discloses a self-priming high-rise public flue, which solves the problem of poor oil smoke discharge due to the internal temperature of the flue being lower than the external temperature and the failure to effectively form a chimney effect. One side of the public flue is connected to the flues of users on each floor, and an air bag heating device is connected to the bottom end of the public flue. A glass fiber reinforced plastic pipe adapted thereto is installed in the inner layer of the public flue to form a thermal insulation layer. The air bag heating device is a solar heating air bag, which heats the air in the flue by sending hot air into the flue through the solar heating air bag installed at the bottom of the flue. The internal temperature of the public flue is made higher than the external temperature, and suction is automatically formed, which promotes the formation of a chimney effect, increases the emission effect of oil smoke in the flues of users on each floor, and avoids the gas in the public flue from flowing back into the flues of users on each floor.

Description

A self-priming high-rise public flue

technical field

The utility model belongs to the field of environmental protection and relates to a flue, in particular to a self-suction type high-rise public flue.

Background technique

At present, the flue ducts of high-rise buildings are usually located on the shady side of the building, where there is no direct sunlight and no heat source, resulting in low temperature in the public flue ducts, and the air density in the flue ducts is greater than that of the outside air, which cannot form a chimney effect. Without the chimney effect, the oil fume cannot It is smoothly discharged from the top of the flue, which makes the fume discharge of the households difficult, and it is inevitable to pour back into the households of the households. The induced draft fan is usually installed on the roof to improve the smoke exhaust effect, but the disadvantages are as follows: 1. The induced draft fan is installed on the roof, because the diameter of the public flue is small, the power of the induced draft fan is limited, and the floor is high, the effect is often not ideal; 2. Manual operation is required to start and stop the induced draft fan, especially during peak cooking hours. However, due to the inconsistent work and rest time of users, it cannot meet the needs of all users, and smoke will still occur.

Utility model content

In order to solve the above-mentioned problems in the prior art, the utility model provides a self-priming high-rise public flue that uses the principle of air convection circulation to generate a chimney effect, automatically forms a suction force, and prevents the gas in the public flue from flowing back into the household.

The utility model adopts the following technical scheme: a self-priming high-rise public flue, one side of the public flue communicates with the flues of users on each floor, and the bottom end of the public flue is connected with an air bag heating device. The layer is installed with its matching glass steel pipe to form a temperature insulation layer.

Further, an inner wall circulating water pipe is arranged along the inner wall of the heat insulation layer, and the inner wall circulating water pipe is connected with the solar water heater on the roof through a solar circulating water pump.

Further, the public flue is provided with resistance wires for direct heating.

Furthermore, the public flue is set on the sunny side of the floor.

Further, the solar circulating water pump is electrically connected to a thermostat for detecting the internal and external temperatures of the public flue, and the thermostat is simultaneously electrically connected to a resistance wire, and the resistance wire is energized through a power supply.

The beneficial effects of the utility model are:

The utility model makes the internal temperature of the public flue higher than the external temperature by installing a heat source on the flue of a high-rise building, promotes the formation of the chimney effect, and inevitably increases the emission effect of oil fume. The utility model uses solar energy to heat the air bag at the bottom of the flue, and passes hot air into the flue to increase the internal temperature of the flue. The inner layer of the flue of the utility model is equipped with glass steel pipes to form a temperature insulation layer, and a circulating water pipeline can be added inside, and connected to the solar water heater on the roof, and the circulating water pump makes the hot water circulation of the circulating water pipeline in the temperature insulation layer to achieve heating. Purpose. Electric resistance wires are added in the flue of the utility model for direct heating. The utility model arranges the flue on the sunny side in house design to reduce the temperature difference between the inside and outside of the flue and make the heating effect better.

Detailed ways

A self-priming high-rise public flue, one side of the public flue communicates with the flues of users on each floor, and the bottom of the public flue 2 is connected with an air bag heating device 5, and the inner layer of the public flue is installed to match it The glass steel pipe forms the insulation layer. The air bag heating device 5 is a solar heating air bag, and the hot air is sent into the flue by the solar heating air bag installed at the bottom of the flue to heat the air in the flue. Make the internal temperature of the public flue higher than the external temperature, automatically form suction, promote the formation of the chimney effect, increase the emission effect of oil fume in the flue 6 of users on each floor, and prevent the gas in the public flue 2 from flowing back into the smoke of users on each floor Road 6.

The utility model arranges the inner wall circulating water pipeline 3 along the inner wall of the heat insulation layer, and the inner wall circulating water pipeline 3 is connected with the solar water heater 4 on the roof through the solar circulating water pump 7 . The hot water in the circulating water pipeline 3 in the thermal insulation layer is circulated through the solar circulating water pump 7 to achieve the purpose of heating the public flue 2 .

The electric resistance wire that directly heats is also installed in the public flue 2 of the utility model. The solar circulating water pump 7 is electrically connected with a thermostat 10. The thermostat 10 is used to detect the chimney thermometer 11 in the public flue and the outdoor thermometer 12 for detecting the temperature outside the public flue. The thermostat 10 is electrically connected to the resistance wire 9 at the same time. Even, resistance wire 9 is energized by power supply 8. When the thermostat 10 detects that the temperature difference between the inside and outside of the public flue is greater than 0°C, the solar circulating water pump 7 is started, and hot water is sent into the inner wall circulating water pipe 3 to heat the inner wall of the flue to play the role of heating the flue, so that the temperature in the flue is greater than 0°C. temperature outside the flue. When the thermostat 10 detects that the temperature difference between the inside and outside of the public flue is greater than 2°C, the resistance wire 9 is started to heat the inner wall of the flue with electric energy, so as to keep the temperature inside the flue greater than the temperature outside the flue. Preferably, when the high-rise public flue 2 is set, it is set on the sunny side of the floor, so as to reduce the temperature difference between the inside and outside of the flue, heat the inside of the flue more effectively, and keep the internal temperature of the flue higher than the external temperature all the time.
