Description

Building is concentrated the mist extractor system

1. affiliated technical field

The utility model relates to the room ventilation technical field, and particularly a kind of building is concentrated the mist extractor system.

2. background technology

There are two kinds of patterns in the building mist extractor system of prior art, and first kind is the dispersion purging mode of no public smoke vent: preformed hole or the perforate on the window that the smoke exhaust pipe of smoke exhaust ventilator stretches out on the wall realize smoke evacuation; Second kind for being provided with the central exhaust pattern of public smoke vent: in the kitchen of every layer of resident family, public smoke vent is provided with preformed hole, and the smoke exhaust pipe of smoke exhaust ventilator is connected with preformed hole realizes smoke evacuation.

There are the following problems for prior art:

1) disperse purging mode: the soot gas discharge is outdoor flies away everywhere, and it is indoor that portion gas can enter resident family along the window of opening; Smoke exhaust pipe is relatively poor with the clearance seal that passes the cavity, and when outdoor reverse wind-force was big, sand and dust can be along in the seal clearance inlet chamber.

2) central exhaust pattern: because smoke exhaust pipe length and vertical height are all less, when the smoke evacuation of more resident family, gas pressure raises in the public smoke vent, partial fume can be along the connection slit of smoke exhaust pipe or the check plate slit of smoke exhaust pipe return to smoke exhaust ventilator the indoor of resident family of stopping using.

3) do not possess from pumping function, after smoke exhaust ventilator was stopped transport, indoor residual soot gas was difficult to emptying for the moment.

3. summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of design, installation, easy maintenance to be provided, prevent emission gases play a reversed role pollution, possess building mist extractor system from pumping function.

The purpose of this utility model can be by realizing by the following technical solutions: a kind of building is concentrated the mist extractor system, comprise and disperse smoke exhaust pipe (1), central exhaust pipe (2), sealing bend (3), be characterized in: disperse smoke exhaust pipe (1) to be fixed in the central exhaust pipe (2), one end of sealing bend (3) is connected with disperseing smoke exhaust pipe (1), and the other end directly or successively is connected with threeway (8) by bellows (6), sealing short tube (7).

Described central exhaust pipe (2) need be offered installing hole, sealing bend (3) is provided with fixing seal ring (4) with an end that disperses smoke exhaust pipe (1) to be connected, fixing seal ring (4) compresses, is fixed in the inner tubal wall of central exhaust pipe (2), is provided with loose gland (5) and makes it compress, be fixed in the outer tube wall of central exhaust pipe (2) on the sealing bend (3) of passing central exhaust pipe (2) tube wall.

The other end of described sealing bend (3) and bellows (6) are when being connected, the other end of bellows (6) is connected with the end that sealing short tube (7) is provided with fixing seal ring (4), and the fixing seal ring (4) that seals on the short tube (7) is sealed the preformed hole of building or the perforate on the window from outdoor; Sealing short tube (7) passes the preformed hole of building or the perforate on the window, passes loose gland (5) again, is connected with threeway (8), and loose gland (5) is sealed the preformed hole of building or the perforate on the window from indoor.

Described central exhaust pipe (2) is formed by connecting by plurality of sections, is fixed in the building outer wall, and each section is combined by two parts.

Two interfaces of other of described threeway (8), one is provided with baffle plate (9), the preceding filter screen for convenience detach (15) that is provided with of baffle plate (9), another interface is connected with smoke exhaust ventilator (16) by bellows (6).

Described central exhaust pipe (2) upper end is provided with hurricane globe (11), described hurricane globe (11) be provided with can be movable verge board (12), verge board (12) upper end is hinged with edge, hurricane globe (11) cover body upper end, verge board (12) lower end is connected with spring (13), the other end of spring (13) is fixed in the tube wall outside that hurricane globe (11) lower end puts in cover, the horizontal end face of hurricane globe (11) lower end is provided with the plurality of rows water hole.

The dispersion smoke exhaust pipe (1) of resident family of the described the superiors passes the set hurricane globe (11) in central exhaust pipe (2) upper end, and the dispersion smoke exhaust pipe (1) of resident family of the superiors upper end is provided with simple and easy rain cover (14).

The beneficial effects of the utility model are:

Therefore building does not need the kitchen mist extractor highway of designs fix, only need continue to continue to use in the prior art the appropriate location of wall reserving hole or from the window-glass the design of perforate get final product thereby relatively simplification of construction; Implement the utility model on this basis and can solve building mist extractor problem better.

Disperse smoke exhaust pipe to increase the vertical setting height(from bottom) of resident family's smoke discharging pipe, strengthened stack effect, the running time that can reduce smoke exhaust ventilator is with using electricity wisely, after smoke exhaust ventilator is stopped transport, indoor residual soot gas can be discharged automatically, can also prevent that the contiguous floors soot gas from going here and there mutually." whole people's energy-saving and emission-reduction handbook---36 daily life behavior energy savings reduce discharging the potentiality quantizating index " according to Department of Science and Technology's establishment: if every smoke exhaust ventilator changes 10 minutes every day less, but power saving in 1 year 12.2 degree, 11.7 kilograms of corresponding minimizing CO2 emissions; If 8,000 ten thousand smoke exhaust ventilators that possess in the whole nation are all taked this measure, but 93.6 ten thousand tons of reducing emission of carbon dioxide are spent in power saving in every year 9.8 hundred million so.

The assembly type system can pull down and clean, checks, repair, and is very convenient.

Can realize the automatic eliminating of accumulation sand and dust in the central exhaust pipe.

Can be applied to building washroom gas purging: the enhancing of stack effect, the running time that can reduce the washroom ventilation fan is with using electricity wisely, after ventilation fan is stopped transport, indoor residual dirty gas can be discharged automatically, can also prevent that the dirty gas of contiguous floors from going here and there mutually, also will make the indoor available sky in washroom ask increase simultaneously.
