Embodiment Construction
[0013] Shell: metal plate, which can be a single layer or more than two layers of interlayer. When the interlayer is installed, the inner layer is made of perforated plate, which can reduce noise and reduce the temperature of the outer air duct. The interlayer air duct is manufactured according to the general structure of the micro-hole plate silencer.
[0014] The opening door of the shell is convenient for cleaning internal parts and clearing the principle of fire particles, for example: the opening door is set on the side of the partition plate.
[0015] Input connection section and output connection section: adopt the general air duct processing method, airtight connection, and make it easy to connect the air ducts on both sides as the principle.
[0016] The cross-sectional area of the input connection section is larger than the cross-sectional area of the output connection section.
[0017] The ports of the input connection section and the output connection section ...

The invention discloses a fire cutting air flue and a fire cutting method. A system consists of a shell, an input connection section, an input fire cutting grid plate group, an isolating plate, a conduction box, an output fire cutting grid plate group and an output connection section; the fire cutting method comprises the following steps: communicating air flow in three chambers isolated inside the fire cutting flue; cutting the flame by using the grid plates which are overlapped at intervals and which are provided with longitudinal and transverse pores; and filtering high-temperature grains by using the grid plates which are overlapped at intervals and which are in different apertures. The fire cutting air flue and the fire cutting method can be widely used in firefighting ventilation systems at various places, members for realizing the air flue can be produced and installed in industrialization, standardization, serialization and generalization, loss caused by fire hazard can be effectively controlled, the flame is rapidly extinguished, and the fire cutting air flue and the fire cutting method belong to the ventilation and firefight field.
Description
technical field [0001] The invention discloses a fire-cutting air duct and a fire-cutting method. The system is composed of a housing, an input connection section, an input fire-cutting grid plate group, a partition plate, a conduction box, an output fire-cutting grid plate group, and an output connecting section. The utility model relates to a fire exhaust system widely applicable to various places, and belongs to the field of ventilation and fire protection. Background technique [0002] The current fire exhaust system relies on the wind speed to eliminate the flame, the flame cannot be cut off for a long time, a fire occurs, and the air duct of the smoke exhaust system is damaged a lot. And research and report on the method of cutting the flame by using the grille perforated plate group. Contents of the invention [0003] The fire cut-off air duct and the fire cut-off method disclosed in the present invention, the fire cut-off method is as follows: the air flow is cond...
