The stirring shaft rotates to stir fire-fighting foam in the fire-fighting foam tank body, a foam extinguishing agent sufficiently flows under stirring of the stirring shaft, precipitation of the foam extinguishing agent can be effectively prevented, the service life of the foam extinguishing agent is guaranteed, and the fire extinguishing effect of the foam extinguishing agent is further guaranteed.

This application discloses an indoor fireproof distribution box, relating to the field of distribution box technology. The fireproof distribution box has a hinged door on its front and ventilation windows on its side walls. A fire extinguishing assembly is installed on the top of the fireproof distribution box. The fire extinguishing assembly includes a mounting base, the lower end of which is fixedly connected to the top of the fireproof distribution box. A gas storage tank is fixedly connected to the surface of the mounting base. The gas storage tank stores fire extinguishing gas, and a gas delivery pipe is fixedly connected to the surface of the gas storage tank. A switch assembly is installed on the surface of the gas delivery pipe. This application delivers fire extinguishing gas into the fire extinguishing pipe via the gas delivery pipe. The gas is then rapidly ejected through multiple exhaust ports on the surface of the fire extinguishing pipe, covering the interior space of the distribution box. Because the fire extinguishing pipe is S-shaped, it can be more widely distributed within the box, allowing the fire extinguishing gas to be more evenly distributed, quickly and effectively extinguishing the fire source, preventing the spread of fire, and reducing damage to the fireproof distribution box and its internal electrical equipment.

The invention relates to the technical field of electrical control cabinets, and discloses a high-voltage electrical control cabinet with flame-retardant, fire-extinguishing and isolation functions. The high-voltage electrical control cabinet with the flame-retardant, fire-extinguishing and isolation functions comprises a control cabinet body, a bottom plate and a partition plate are fixedly installed on the inner wall of the control cabinet body, the bottom plate and the partition plate are horizontally arranged, the bottom plate is arranged below the partition plate, and flame-retardant and fire-extinguishing structures are installed at the top end of the bottom plate and the top end of the partition plate; high-voltage electrical control assemblies in the high-voltage electrical control cabinet are installed at the top end of a bottom plate and the top end of a partition plate respectively, a flame-retardant fire extinguishing structure is in a C shape, an opening of the flame-retardant fire extinguishing structure faces downwards, and the high-voltage electrical control assemblies are covered with the flame-retardant fire extinguishing structure; a gap is reserved between the flame-retardant fire extinguishing structure and the inner wall of the control cabinet body; the fire extinguishing agent can form a uniform distribution effect when falling on the high-voltage electrical control assembly along with the high-pressure gas, the fire extinguishing effect of the fire extinguishing agent is guaranteed, the high-pressure gas can be fully mixed with the fire extinguishing agent in the early stage of fire extinguishing, and therefore the rapid fire extinguishing effect is achieved.

The present application relates to the technical field of flue gas treatment, in particular to a centralized treatment equipment for flue gas of a biomass steam boiler, which comprises a spark catcher, the spark catcher comprises a shell and an inner seat in the shell, the shell is provided with an air inlet, an air outlet and a residue discharge port, the air inlet is communicated with a flue gas outlet of the biomass steam boiler; the inner seat is in a circular table structure, and the small end faces the air inlet; a plurality of support sheets are arranged between the shell and the inner seat, the support sheets are arranged along the circumference of the inner seat, and the support sheets are spirally arranged along the axis of the inner seat; each support sheet is sleeved with a flow guide ring belt, the flow guide ring belt forms a closed motion loop, and a flow channel is formed between adjacent flow guide ring belts, the flow channel is used for passing the flue gas generated by the biomass steam boiler.
