Problems solved by technology

Because the oil in the lampblack will adhere to the inner wall of the flue, after a long time of use, more oil will adhere to the inside of the flue, and it is easy to cause a fire when it encounters an open flame
The existing flue cleaning equipment only realizes the cleaning of the flue by spraying water into the flue. This inclined method cannot remove the oil attached to the inner wall of the flue, which leads to serious safety hazards in the flue now.

Embodiment 1

[0032] Such as figure 1 Shown: the length of the baffle 2 is greater than the length of the cross section of the flue 1, the width of the baffle 2 is greater than the width of the cross section of the flue, there are two baffles 2, and the two baffles 2 are detachably installed on the flue 1 and the two ends of the flue 1 are closed to prevent the flue 1 from communicating with the atmosphere, and to prevent the fireproof powder sprayed into the flue 1 from entering the atmosphere and polluting the environment. The baffle plate 2 can also be rotated and installed at the end of the flue 1, so that the end of the flue 1 is closed before the fireproof powder is sprayed into the flue 1, and the end of the flue 1 is opened after the fireproof powder is recovered. convenient.

[0033] In this embodiment, two injectors 3 are provided, and the two injectors 3 are respectively arranged at both ends of the flue 1 , and the medium outlets of the two injectors 3 communicate with both end...

Embodiment 2

[0050] Such as Figure 7 As shown: the difference between embodiment 2 and embodiment 1 is that there is only one injector 3, and the injector 3 is arranged on the left side of the flue 1, and the middle part of the baffle plate 2 on the left is provided with a powder inlet, and the injector 3 The medium outlet of 3 communicates with the powder inlet of the baffle plate 2 on the left.

Abstract

The invention discloses a flue fire protection device and belongs to the technical field of fire protection equipment. The flue fire protection device is characterized by comprising baffles (2) and injectors (3), wherein the baffles (2) and the injectors (3) are arranged at the two ends of a flue (1), the number of the baffles (2) is two, the two baffles (2) are detachably installed at the two ends of the flue (1) and seal the two ends of the flue (1), high-pressure medium inlets of the injectors (3) are connected with compressed air, low-pressure medium inlets of the injectors (3) are connected with the discharge ends of fireproof powder containers, and medium outlets of the injectors (3) communicate with the flue (1). The injectors of the flue fire protection device can inject fireproofpowder into the flue, and the fireproof powder will be attached to the oil face of a flue wall after entering the flue, so that the oil face is isolated from air in the flue, no fire disaster is caused even if open fire is produced in the flue, the fire disaster happening rate is greatly lowered, the risk that a fire disaster happens in the flue is lowered, and the potential safety hazard is lowered.

Description

technical field [0001] A flue fire-fighting device belongs to the technical field of fire-fighting equipment. Background technique [0002] A flue is a tubular passage for exhaust gas and smoke. Restaurants or residential buildings usually have a flue to facilitate the emission of oil fume. Since the oil in the lampblack will adhere to the inner wall of the flue, after long-term use, more oil will adhere to the inside of the flue, and it is easy to cause a fire when it encounters an open flame. The existing flue cleaning equipment only realizes the cleaning of the flue by spraying water into the flue. This inclined method cannot remove the oil attached to the inner wall of the flue, which leads to serious safety hazards in the flue. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a flue fire-fighting device that prevents fires caused by open flames by adhering the f...
