Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire water supply systems, in particular to a fireproof separation water curtain water supply system in a coal conveying building of a small power station. Background Art
[0002] There are many requirements for installing fire separation water curtains indoors in coal handling buildings of power plants. However, due to the special characteristics of fire such as small working space in some coal handling buildings of power plants, limited entrances and exits for fire rescue and fire extinguishing, which is extremely unfavorable for fire fighting operations, the new version of "Code for Design of Fire Protection for Thermal Power Plants and Substations" GB50229-2019 has put forward new requirements. Fire separation water curtains should be installed at the connection between the operating trestle and transfer station, silo, coal crusher room, and main plant building in small power plants, and the layout needs to be redesigned. Summary of the invention
[0003] In order to solve the fire protection demand of existing small spaces, the utility model provides a fire-proof separation water curtain water supply system in a coal handling building of a small power station, which can meet the fire protection demand.
[0004] The technical solution is as follows: a fire-proof separation water curtain water supply system in a coal transportation building of a small power station, characterized in that it includes a main fire-fighting water supply pipe, the main fire-fighting water supply pipe includes a first vertical section, a first horizontal section, a second vertical section, and a second horizontal section, a gate valve, a pressure reducing orifice plate and a Y-type filter are sequentially arranged on the first horizontal section, a deluge valve group is installed on the second vertical section, two rows of open nozzles are installed on the second horizontal section, the distance between the second horizontal section and the bottom of the beam of the building is not less than 0.1m, and the spacing between adjacent open nozzles in the same row is not more than 1400mm.
[0005] It is further characterized in that the node between the first vertical section and the first horizontal section is connected to the factory fire protection pipeline through a control valve.
[0006] After the utility model is adopted, the main fire water supply pipe provides fire water, which can be controlled by the gate valve and the deluge valve group to spray water curtains from two rows of open nozzles to form a densely sprayed water wall, thereby meeting the fire protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 This is a schematic diagram of the fire protection system of the utility model;
[0008] Figure 2 This is the fire fighting arrangement diagram of the present utility model. DETAILED DESCRIPTION
[0009] See Figure 1As shown, a fire separation water curtain water supply system in a coal handling building of a small power station includes a main fire water supply pipe 1, the main fire water supply pipe 1 includes a first vertical section 1-1, a first horizontal section 1-2, a second vertical section 1-3, and a second horizontal section 1-4, a gate valve 2, a pressure reducing orifice 3 and a Y-type filter 4 are sequentially arranged on the first horizontal section 1-2, a deluge valve group 5 is installed on the second vertical section 1-3, two rows of open nozzles 6 are installed on the second horizontal section 1-4, the distance between the second horizontal section 1-4 and the bottom of the beam of the building is not less than 0.1m, the spacing between adjacent open nozzles 6 in the same row is not more than 1400mm, generally 1100mm is selected, and the spacing between the two rows of open nozzles 6 is 1200mm.
[0010] The specific layout is as follows Figure 2 As shown, the main fire water supply pipe 1 penetrates vertically from the top of the wall, then extends horizontally for a section and then vertically upwards to 0.1m from the bottom of the top beam, and then extends horizontally, and two rows of four groups of open sprinklers are arranged to form a fire separation water curtain.
[0011] The node between the first vertical section 1-1 and the first horizontal section 1-2 is connected to the plant fire protection pipeline 1-6 through the control valve 1-5.
