Description

Technical Field

[0001] This utility model relates to a collection facility for leaked liquids, specifically a collection facility for leaked liquids from a hazardous waste temporary storage facility. Background Technology

[0002] Hazardous waste temporary storage facilities are warehouse-style storage facilities used to store one or more types and forms of hazardous waste. During the storage of liquid or semi-solid hazardous waste in these facilities, if the storage containers break or tip over, leaks or spills of the liquid may occur, even resulting in liquid flowing everywhere, posing challenges to collection and cleanup. These liquids from the liquid or semi-solid hazardous waste may possess toxic, flammable, or corrosive properties, and after collection and cleanup, they must be collected, stored, and managed as hazardous waste.

[0003] Although existing hazardous waste temporary storage facilities are equipped with dikes, leaks or spills of liquid or semi-solid hazardous waste are trapped within the same area due to the dikes. The leaked liquid often overflows within the dike, making collection and cleanup difficult, thus causing temporary soaking or contamination of other hazardous waste stored in the same area. Furthermore, the dikes only serve to prevent leaks, not to collect them. In addition, the presence of dikes often hinders forklift handling and obstructs forklift movement, while dikes with forklift entrances and exits are ineffective at preventing liquid from flowing out of the area. These issues lead to various inappropriate practices in use, daily maintenance, and management. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a collection facility for leaked liquid in a hazardous waste temporary storage facility, which can both block the crossflow of leaked liquid and collect the liquid to prevent the waste liquid from soaking or contaminating other stored hazardous waste, while facilitating the daily entry and exit and loading and unloading work of forklifts.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a collection facility for leaked liquid in a hazardous waste temporary storage facility, including a diversion channel, a collection tank, and a grate cover. The diversion channel is located at the edge of the ground slope of the liquid or semi-solid hazardous waste temporary storage area of ​​the hazardous waste temporary storage facility, and the diversion channel has a slope. The collection tank is connected to one or both ends of the diversion channel, and the bottom elevation of the collection tank is set below the ±0.00 horizontal plane. The top of the diversion channel and the collection tank are respectively covered with the grate cover, and the upper surface of the grate cover is flush with the ground.

[0006] After this collection facility is put into use, waste liquid leaking or spilling from storage containers in the liquid or semi-solid hazardous waste temporary storage area flows by gravity into the diversion channel along the slope of the ground in the liquid or semi-solid hazardous waste temporary storage area, and then flows by gravity into the collection tank along the slope of the diversion channel for collection. Workers open the grate cover and transfer the waste liquid collected in the collection tank to a special hazardous waste container using conventional methods such as pump suction and container emptying. This is managed according to the regulations for temporary storage of hazardous waste in a hazardous waste warehouse, thus preventing waste liquid from flowing everywhere and soaking or contaminating other stored hazardous waste, and reducing the burden of waste liquid collection and cleaning. After the leaked or spilled waste liquid has been collected, transferred, and treated, workers close the grate cover to facilitate daily forklift access and loading / unloading operations.

[0007] Preferably, the slope of the ground is 3‰ to 1%, and the slope of the guide channel is 3% to 5%.

[0008] Preferably, the bottom elevation of the liquid collection tank is 200mm to 400mm different from the bottom elevation of the guide channel.

[0009] Preferably, the guide channel has a symmetrical design with a high middle and low ends, and the two ends of the guide channel are respectively connected to the liquid collection tank.

[0010] Preferably, the grate cover is a cast iron grate cover with a rust removal grade of St2, and the surface of the grate cover is provided with an anti-corrosion coating to ensure the strength and anti-corrosion effect of the grate cover.

[0011] Preferably, the collection tank is equipped with a level gauge and / or a gas alarm. Gas alarms, such as explosion-proof or non-explosion-proof alarms for flammable or toxic gases, can further improve the safety of the facility.

[0012] Compared with the prior art, the present invention has the following advantages: The collection facility of the present invention can be used to collect liquid or semi-solid hazardous waste stored in the hazardous waste temporary storage facility after leakage or spillage. It can not only block the crossflow of leaked liquid, but also collect the liquid, avoiding the waste liquid from soaking or contaminating other stored hazardous waste. At the same time, it facilitates the daily entry and exit of forklifts and loading and unloading work, and solves the problems of difficult cleaning after liquid leakage or spillage and the obstruction of forklift entry and exit for loading and unloading by the dike. It meets the design requirements and is easy to operate and use. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] The embodiment of the hazardous waste temporary storage facility for collecting leaked liquid, such as Figures 1-3 As shown, the hazardous waste temporary storage facility 4 includes a liquid or semi-solid hazardous waste temporary storage area 41 and a solid hazardous waste temporary storage area 42. The collection facility includes a diversion channel 1, a collection tank 2, and a grate cover 3. The diversion channel 1 is located at the edge of the ground slope of the liquid or semi-solid hazardous waste temporary storage area 41 of the hazardous waste temporary storage facility. The ground slope is 1%, and the diversion channel 1 has a 5% slope. The diversion channel 1 has a symmetrical design with a high middle and low ends. The two ends of the diversion channel 1 are respectively connected to the collection tank 2. The bottom elevation of the collection tank 2 is set below the ±0.00 horizontal plane. The top of the diversion channel 1 and the collection tank 2 are respectively covered with a grate cover 3, and the upper surface of the grate cover 3 is flush with the ground.

[0018] In this embodiment, the collection tank 2 is 500mm long and 500mm wide. The total volume of the collection tank 2 is not less than the greater of the largest liquid / semi-solid waste storage container volume in the liquid / semi-solid hazardous waste temporary storage area 41 or 1 / 10 of the total liquid / semi-solid waste storage capacity. The bottom elevation of the collection tank 2 differs from the bottom elevation of the guide channel 1 by 200mm to 400mm. The bottoms of the guide channel 1 and the collection tank 2 adopt the same existing anti-seepage and anti-corrosion processes as the liquid / semi-solid hazardous waste temporary storage area 41, including anti-seepage and anti-corrosion structures or materials. A level gauge and / or a gas alarm may be installed in the collection tank 2.

[0019] In this embodiment, the grate cover 3 is a cast iron grate cover with a rust removal grade of St2 and a size of 400×280mm. The surface of the grate cover 3 is coated with an existing anti-corrosion coating to form an anti-corrosion coating with a total thickness of 150μm.

[0020] After the aforementioned collection facilities are put into use, waste liquid leaking or spilling from the storage containers in the liquid or semi-solid hazardous waste temporary storage area 41 will flow by gravity into the diversion channel 1 along a 1% slope of the ground in the liquid or semi-solid hazardous waste temporary storage area 41, and then flow by gravity into the collection tanks 2 at both ends of the diversion channel 1 along a 5% slope, where it will be collected. Workers open the grate cover 3 and transfer the waste liquid collected in the collection tank 2 to a special hazardous waste container using conventional methods such as pump suction and container emptying. This is managed according to the regulations for the temporary storage of hazardous waste in the hazardous waste warehouse, thereby preventing waste liquid from flowing everywhere and soaking or contaminating other stored hazardous waste, and reducing the burden of waste liquid collection and cleaning. After the leaked or spilled waste liquid has been collected, transferred, and treated, workers close the grate cover 3 to facilitate the daily entry and exit of forklifts and loading and unloading operations.
