Description

Technical fields:

[0001] This invention belongs to the field of substation fire protection technology, and specifically relates to a skid-mounted fire protection equipment compartment system for transformers in desert areas. Background technology:

[0002] Desert, Gobi, and arid regions are vast, with diverse climates and abundant wind and solar energy resources. In recent years, these regions have taken the lead nationwide in constructing a new power system based on new energy sources, accelerating the development of large-scale power bases centered in these areas. Substations, as a core component of the power system, are directly related to the stability and reliability of the entire system due to their fire safety. Statistics show that electrical equipment in substations prone to fires includes transformers, capacitors, and oil circuit breakers. Among these, oil-immersed transformers are the most common, filled with flammable transformer oil that serves both insulation and heat dissipation functions. When the temperature is too high, the transformer oil easily decomposes into hydrogen, methane, and acetylene gases, causing a rapid increase in internal pressure and leading to the rupture of weak points such as bushings and welds. This can trigger complex combustion patterns such as jet fires, oil pool fires, and flowing fires, greatly complicating firefighting efforts.

[0003] Traditional substation fire protection facilities mitigate the impact of the harsh environment of desert and Gobi areas by constructing buildings such as fire pump rooms. However, construction in such harsh environments presents numerous challenges, including long construction periods, low construction standards, and non-standard equipment installation. Furthermore, water scarcity and frequent extreme weather events such as sandstorms in desert and Gobi areas can contaminate fire-fighting water sources. Organic, inorganic, and microbial particles can easily clog fire-fighting nozzles, hindering the effective activation and efficient fire suppression of the system. Additionally, the frequent severe weather in desert and Gobi areas can cause power supply failures in fire equipment compartments, preventing timely power supply to fire-fighting equipment in the fire control room and impacting the normal operation and maintenance of the entire fire protection system.

[0043] The mud-water separator is mounted on the support frame 234. The circulating pump 232 and the ultrafiltration filter 233 are respectively fixed on the inner side wall of the fire equipment compartment 2. The bottom of the support frame 234 is provided with support frame pulleys 2341 and support frame pins 2342. The bottom plate of the fire equipment compartment 2 has a support frame fixing hole (not shown in the figure) that matches the support frame pins 2342.

[0051] Work process:

[0052] The water circulation purification system 23 for the water circulation purification in the buffer tank 221 includes two processes: filtration and forward flushing. The filtration process is as follows: close the flushing drain electric valve 2333, the mud-water separator outlet electric valve 2322, and the cleaning spray valve 46; open the buffer tank outlet electric valve 2214 and the buffer tank inlet electric valve 2212; the circulation pump 232 draws water and pressurizes it, drawing water from the bottom of the buffer tank 221. The water then enters the ultrafiltration filter 233 through the buffer tank outlet pipe 2213 and is filtered by the ultrafiltration membrane module 2334. Inorganic, organic, and pathogenic microbial particles in the water are efficiently intercepted in the ultrafiltration filter 233. The filtered water returns to the buffer tank 221 through the buffer tank inlet pipe 2211. One cycle of filtration in the buffer tank 221 is completed in one hour. After the cycle filtration is completed, the forward flushing process begins. The forward flushing process involves maintaining the mud... The water separator outlet electric valve 2322 and the cleaning spray valve 46 are closed, the buffer water tank outlet electric valve 2214 is kept open, the buffer water tank inlet electric valve 2212 is closed, the flushing drain electric valve 2333 is opened, the circulation pump 232 draws water and pressurizes it, drawing water from the bottom of the buffer water tank 221 and through the buffer water tank outlet pipe 2213 into the ultrafiltration filter 233, performing surface flushing on the ultrafiltration membrane module 2334, washing off the dirt attached to the surface of the ultrafiltration membrane, and flowing with the water through the flushing drain pipe 2332 into the inlet area 2313 of the mud-water separator 231. Large particles of dirt are deposited at the bottom, and the clean water filtered by the filter screen 2311 enters the clean water area 2312 for storage. The flushing lasts for 1 minute, ending the forward flushing process. Through regular circulation filtration and forward flushing, the water quality in the buffer water tank 221 can be effectively guaranteed, and the ultrafiltration membrane module 2334 can always be in the best working condition.

[0053] The water circulation purification system 23, used for the recycling and reuse of wastewater from photovoltaic panel cleaning 41, includes two processes: filtration and forward rinsing. The filtration process is as follows: The flushing drain electric valve 2333, the buffer tank outlet electric valve 2214, and the buffer tank inlet electric valve 2212 are closed. The mud-water separator outlet electric valve 2322 and the cleaning spray valve 46 are opened. The circulation pump 232 draws in water and pressurizes it, drawing water from the clear water zone 2312 of the mud-water separator 231. The water then enters the ultrafiltration filter 233 through the mud-water separator outlet pipe 2321 and is filtered by the ultrafiltration membrane module 2334, removing particles larger than 0.0 mm. 3µm pollutant particles are efficiently intercepted in the ultrafiltration filter 233. Filtered water enters the cleaning spray pipe 45 through the clean water outlet of the ultrafiltration filter 233 and is sprayed out from the cleaning spray head 47 to clean the photovoltaic panel 41. The cleaning wastewater, carrying a large amount of sand and dust, is collected in the collection tank 42 and enters the inlet area 2313 of the mud-water separator 231 through the drain pipe 48. The mud and sand particles quickly settle downwards to the bottom of the inlet area due to their own weight. After concentration, the mud is discharged from the system by periodically opening the mud discharge electric valve 2315. The remaining fine pollutant particles rise with the water flow. When they pass through the filter screen 2311, the particle size is larger than that of the filter screen 2311. Pollutant particles with a pore size of 311 are further trapped, and the filtered clean water is returned to the clean water zone 2312, realizing the recycling of the photovoltaic panel 41 cleaning wastewater. The cleaning time of photovoltaic panel 41 is set to 10 minutes. When the cleaning time is reached, the filtration ends and the forward rinsing process begins. The operation method of the forward rinsing process is as follows: keep the mud-water separator outlet electric valve 2322 and the cleaning spray valve 46 closed, keep the buffer water tank outlet electric valve 2214 open, close the buffer water tank inlet electric valve 2212, open the flushing drain electric valve 2333, and the circulation pump 232 draws water and pressurizes it, drawing water from the bottom of the buffer water tank 221. The water enters the ultrafiltration filter 233 through the outlet pipe 2213 of the buffer tank to perform surface rinsing on the ultrafiltration membrane module 2334, washing off the dirt attached to the surface of the ultrafiltration membrane. The dirt then flows with the water through the rinsing drain pipe 2332 into the inlet area 2313 of the mud-water separator 231. Large particles of dirt settle downwards to the bottom. The clean water filtered by the filter screen 2311 enters the clean water area 2312 for storage. The rinsing lasts for 0.5-1 minute, ending the forward rinsing process. Through regular filtration and forward rinsing, the water quality of the photovoltaic panel 41 cleaning water can be effectively guaranteed, and the ultrafiltration membrane module 2334 can always be in optimal working condition.

[0054] During the filtration and backwashing period, the water circulation purification system 23 intercepts fine particles in the inlet water zone 2313 to complete the static water sedimentation process and deposits them at the bottom of the inlet water zone 2313. The concentrated sludge is discharged from the water circulation purification system 23 by periodically opening the sludge discharge electric valve 2315.

[0055] The water volume reduced due to the sludge discharge of the water circulation purification system 23 can be replenished by fire water source. The specific operation method is as follows: open the water supply valve 2217, and fire water source flows in through the water supply pipe 2216 until the buffer water tank 221 reaches the set maximum water level.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
