Embodiment Construction

[0015] The method for quick fire extinguishing of the gas boiler of the present invention is as follows: install a pneumatic quick-closing valve on the east and west branch pipes and four-corner branch pipes of the raw gas, and when the MFT operates, the pneumatic quick-closing valve responds within 1 second to quickly close and cut off the incoming gas; at the same time , Before the last valve of the branch pipe of the burner at each corner of the gas, nitrogen is introduced to block it; the leaked gas is blocked by nitrogen gas due to the fouling of the pipeline caused by the jamming or lax closing of the valve.

[0016] In order to realize the above method, the present invention proposes as figure 1 Gas boiler quick fire extinguishing device: This device includes gas pipelines leading into the furnace, and pneumatic quick-closing valves are respectively installed on the gas pipelines, and each pneumatic quick-closing valve is connected to the gas storage tank through the gas...

Abstract

The invention discloses a method and a device for rapidly carrying out fire extinguishment on a gas boiler. Pneumatic quick-closing valves are arranged on east and west crude gas branch pipes and four corner branch pipes; when an MFT (Master Fuel Trip) actuates, the pneumatic quick-closing valves respond to the action in 1S to be rapidly closed to cut off incoming gas; meanwhile, nitrogen is filled to carry out blocking in front of the last valve of each gas corner burner branch pipe; blockage is carried out by nitrogen for gas leakage caused by the case that the valves are jammed or are not tightly closed due to scale depositing in pipelines. According to the invention, by changing electrical quick-closing valves into the pneumatic quick-closing valves and adding nitrogen to extinguish a fire, the condition that a pipe network cannot be controlled due to loss of pressure can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of boilers, and relates to a fire extinguishing method, in particular to a method and device for quickly extinguishing a gas boiler. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical ene...
