[0016] The present application has the following advantages:

[0017] 1、In the present application, the lifting seat is installed at the bottom of the outer box, the inner lining bin is installed at the top end of the lifting seat, the flow guide groove is arranged in the middle of the inner lining bin, the collection well is installed at the end of the flow guide groove, and the grid plate is laid at the top end of the inner lining bin. When storing hazardous liquid waste, the staff puts each barrel of hazardous liquid waste into the inner lining bin of the equipment through the external anti-skid table. If the hazardous liquid waste leaks, it will flow into the flow guide groove along the grid plate and then flow into the collection well. When the leakage amount is too large, the collection well, the flow guide groove and all the grid plates in the inner lining bin will be filled in turn. Through the overall storage of the collection well, the flow guide groove and the grid plate, the ground position in the equipment is still in the accessible state without storing hazardous liquid waste. That is, the equipment is lifted by the lifting seat to provide sufficient depth for the collection well and the flow guide groove, and the grid plate is laid in the equipment. In this way, the storage capacity of the equipment for high leakage amount of hazardous liquid solution is improved.

[0018] Further, by setting multiple partition plates inside the device, installing a partition plate at the bottom between two adjacent partition plates, setting a recording table with a ledger on one side of the inner substrate bin, and installing an inner recording camera and a warning unit at the top side inside the device, connecting the inner recording camera with the external electric control box, and electrically connecting the electric control box with the monitoring terminal, when leakage occurs inside the device, the caregivers around the device are reminded by the buzzer in the warning unit, and the remote monitoring personnel synchronously receive the warning alarm information, improving the early warning capability of the device for leakage. Even if the leakage is too fast to cause a large amount of leakage, the staff can contact professional hazardous waste disposal staff to enter the device, quickly grasp the specific information of the leaked hazardous waste products with the help of the ledger and the partition plate, and quickly develop a corresponding treatment plan. The technical advantage is that the elevated inner substrate bin cooperates with the laid grid plate to enable the device to store a large amount of leaked hazardous waste liquid, providing an effective space for the subsequent staff to enter and process, and cooperating with the partition plate and the recording table to accurately record the information of the hazardous waste enables the entering staff to quickly grasp the specific information of the leaked material, thereby quickly developing a suitable treatment plan. That is, the high capacity of the device for hazardous liquid and the real-time monitoring and clear recording of the information of the hazardous liquid in the case construct an integrated technical solution, which aims to effectively solve the problem of quick entry and processing when a large amount of hazardous liquid leaks in the device, thereby improving the safety of the device during use.

The lifting seat 2 is used to increase the total liquid storage space of the flow channel 4, the collection well 5, and each grid plate 6. Partition plates 7 are evenly arranged on both sides of the flow channel 4 in the inner liner compartment 3, and an interior top compartment 8 is installed at the top. The interior top compartment 8 has a partition plate installed between the two partition plates 7. The interior compartment 9 has an internal video recorder 10 installed on one side of the top, a recording table 11 on one side of the inner lining compartment 3, and an electrical control box 12 installed on the outside of the outer trim box 1. The internal video recorder 10 is used to quickly locate the stored items in conjunction with the recording table 11. A fireproof layer 13 is installed between the outer trim box 1 and the inner lining compartment 3. A protective layer is coated on the inside of the inner lining compartment 3, and the inner lining compartment 3 is integrally welded. At least one ventilation fan 14 is installed on one side of the top of the interior top compartment 8, and a warning unit 15 is installed on the top. A processing component 16 is detachably connected to the outside of the ventilation fan 14. The processing component 16 is used to process the volatile gases of the stored items on both sides of the inner lining compartment 3. An explosion-proof door 17 is installed on one side of the outer trim box 1.

[0035] It should be noted that the outer box 1 located outside the device and the inner top bin 8 are both waterproof boards, which are used to prevent external rainwater from eroding into the interior of the device, and are preferably polyvinyl chloride waterproof boards; the outer box 1 is fixedly connected with a warning board 18 on one side of the explosion-proof door 17 and the side perpendicular to the side, and the warning board 18 is used to identify the device as a hazardous waste storage facility to avoid external force and pedestrian miscontact; the explosion-proof door 17 (see Figure 1 ) is provided with a window 19 at the top, which is used for the staff to regularly patrol the storage condition inside the device, and a handle is provided at the top and equipped with a double-hole lock 20, that is, a double-hole lock that can only be opened by two people, so as to ensure the supervision effect when opening and improve the safety of device storage; the explosion-proof lamp 21 is installed at the middle of the top end of the inner top bin 8, which is convenient for cooperating with the internal video recorder 10 to keep long-time uninterrupted monitoring; four lifting lugs 22 are installed at the top end of the outer box 1, which is convenient for the overall lifting and moving of the device.

[0036] As shown in Figure 2 , Figures 5 to 7 , the bottom surface of the collection well 5 is lower than the bottom surface of the flow guide groove 4, and the height of the lifting seat 2 is not less than 30 cm;

[0037] The top end of the grid plate 6 is flush with the bottom surface of the explosion-proof door 17, the outer side of the explosion-proof door 17 is provided with an anti-skid table 23, and the total liquid storage capacity of the flow guide groove 4, the grid plate 6 and the collection well 5 is greater than 1 / 3 of the total storage capacity;

[0038] It should be noted that the collection well 5 is located away from the explosion-proof door 17 and is in communication with one end of the flow guide groove 4, and the depth of the collection well 5 is greater than the depth of the flow guide groove 4, so that the flow guide groove 4 is used to reduce the contact area between the bottom of the device and the ground, reduce the corrosion of the bottom of the device by acid soil, rainwater and other factors, and more importantly, the flow guide groove 4 and the collection well 5 are reserved with a deeper storage space to improve the liquid collection capacity of the flow guide groove 4 and the collection well 5, and a large number of grid plates 6 are uniformly laid on the bottom surface inside the bottom bin 3, and the grid plates 6 are preferably made of glass fiber to avoid corrosion by the stored materials;

[0039] The dangerous waste solution stored inside the device will be transported to the guide groove 4 along the grid plate 6 after leakage, and will be transmitted to the collection well 5 along the guide groove 4, and as the leakage amount increases, the collection well 5, the guide groove 4 and the grid plate 6 will be filled in turn, however, due to the use of the lifting seat 2 and the strong total liquid storage capacity of the three places, preferably, the total liquid storage capacity of the collection well 5, the guide groove 4 and the grid plate 6 is greater than 1 / 3 of the capacity of a single tank of dangerous waste solution inside the device or the total liquid storage amount inside the device, and the larger value of the two is taken, then the device inside can still maintain the state of the top of the grid plate 6 as the landing for the treatment personnel to enter when facing a serious leakage accident with high leakage amount, which greatly improves the ability of the device to fight against sudden leakage of dangerous waste solution, and the purpose is to enable the device to still maintain the ability of convenient access for treatment personnel when facing a large amount of leakage of dangerous waste solution, thereby improving the storage safety of the device and avoiding the situation that the leakage of large-capacity dangerous waste solution cannot be handled;

[0040] In addition, since the device uses the lifting seat 2, and the height of the explosion-proof door 17 is flush with the height of the grid plate 6 inside, a non-slip platform 23 is provided outside to ensure that various dangerous waste can be conveniently transported to the inside of the device, wherein the lifting seat 2 is made of high-strength structural steel, which increases the overall strength of the device and facilitates the overall lifting and transfer of the lifting lug 22.

[0041] As shown in Figures 2 to 4 The inner lining bottom bin 3 has a side height of 1.5 meters, the inner lining bottom bin 3, the guide groove 4 and the collection well 5 are integrally welded by steel, the inner frame further includes a side beam 24 arranged on the side of the outer decorative box 1, a top beam 25 is arranged between the inner side top of the outer decorative box 1 and the inner decorative top bin 8, and the fireproof layer 13 is arranged between the two sides and the top of the inner side of the outer decorative box 1;

[0042] The protective layer includes a corrosion-resistant paint 26 adjacent to the outer side of the inner lining bottom bin 3, two layers of impermeable paint 27 are coated outside the corrosion-resistant paint 26, and a reinforcing cloth 28 is arranged between the two adjacent layers between the inner lining bottom bin 3 and the outermost impermeable paint 27;

[0043] It should be noted that the inner substrate bin 3 and the flow guide groove 4 and the collection well 5 are integrally welded by carbon steel, thereby forming an integrated boat-shaped inner lining, thereby improving the sealing performance of the equipment during use, and the leakage of the waste liquid cannot penetrate the integrated structure to the bottom surface, thereby causing pollution of the soil and groundwater in the area; On this basis, the fireproof layer 13 is filled and laid in the space blocked by the inner frame on the inside of the outer decorative box 1, the fireproof layer 13 is preferably made of rock wool sandwich board, in addition, the protective layer is arranged in the order of glass cloth, anticorrosive asphalt paint, glass cloth, epoxy resin impermeable paint, glass cloth and epoxy resin impermeable paint on the inside of the boat-shaped inner lining, and the reinforcing cloth 28 is preferably glass cloth, so that the fireproof layer 13 can avoid internal spontaneous combustion, burn through the outer decorative box 1 to cause leakage, the impermeable paint 27 located on the top layer of the inner lining can avoid the leakage of the hazardous waste liquid, and the anticorrosive paint 26 on the bottom layer can avoid the leakage caused by external corrosion, the purpose is to improve the corrosion resistance, impermeability and fire resistance of the equipment through the integrally welded inner lining and the multi-layer protective layer, avoid the substantial damage to the equipment that can cause hazardous waste leakage caused by external interference from the structure, thereby improving the risk resistance of the equipment during use and improving the use safety.

[0044] As shown in Figure 2 and Figure 8 The inner recorder 10 is located at the top of the inner decorative top bin 8 away from the explosion-proof door 17 on one side, the recording table 11 is installed on the side close to the explosion-proof door 17, the inner recorder 10 and the early warning unit 15 are electrically connected with the electric control box 12, the electric control box 12 is built-in signal transceiver module and connected with remote monitoring terminal, the partition plate 9 is used to identify the type of hazardous waste stored between the two adjacent partition plates 7 below;

[0045] It should be noted that the partition plate 7 is used to block the inner lining of the equipment into multiple storage areas, and the partition plate 9 is installed at the top of each storage area, and the partition plate 9 is used to record the type of hazardous waste stored in each storage area. The recording table 11 collects the detailed information of the storage amount and the time of the storage and the like of the storage material in each storage area, so as to record the storage material in the equipment in detail; The inner recorder 10 and the early warning unit 15 cooperate with the explosion-proof lamp 21 to monitor the real-time storage state of the hazardous waste in the equipment, when the leakage triggers the alarm system of the early warning unit 15, the corresponding information of the inner recorder 10 and the early warning unit 15 is accepted by the signal transceiver module in the electric control box 12 connected with it and sent to the remote terminal, and the remote monitoring terminal receives and processes the subsequent response;

[0046] The storage locations are clearly divided by partitions 7 and partitions 9 to prevent the mixing of different types of hazardous waste materials and avoid the risk of secondary hazards caused by mutual reactions during storage. The recording station 11 records detailed information about the internal storage, and the internal video recorder 10 monitors the storage status in real time. The purpose is to isolate the internal storage and record and monitor it in detail. In the event of a leak, the leak can be detected remotely through video monitoring. When personnel arrive at the scene, they can quickly obtain all information about the leaked substance by using the information recorded on the partitions 9 and the recording station 11. This allows for a faster response to the leak and the development of appropriate treatment methods. This also improves the equipment's ability to respond quickly to sudden leaks.

[0047] In addition, detailed information recording can also avoid erroneous transfers during daily access. Furthermore, an external video recorder is installed on one side of the top of the explosion-proof door 17 in the outer casing 1 to cooperate with the internal video recorder 10 for information comparison.

[0048] The early warning unit 15 has a built-in combustible gas concentration sensor, volatile organic compound concentration sensor, acid mist sensor and buzzer. The early warning unit 15 is electrically connected to the electrical control box 12. The electrical control box 12 has a built-in solenoid valve, which is electrically connected to the ventilation fan 14.

[0049] It should be noted that the solenoid valve is an induction valve. The early warning unit 15 integrates multiple sensors to adapt to the storage needs of various hazardous waste materials in the equipment. When a corresponding leak occurs inside the equipment, the early warning unit 15 will immediately trigger an early warning message and alert the staff through a buzzer. The early warning message is sent to the control center through the signal transmission module inside the electrical control box 12 so that the control center can contact professional personnel for handling in a timely manner. Preferably, when all sensors in the early warning unit 15 are within the normal concentration range, the electrical control box 12 controls the solenoid valve to be in the closed state, and the ventilation fan 14 does not work. When a sensor in the early warning unit 15 is triggered, the electrical control box 12 starts the solenoid valve, and the ventilation fan 14 performs a suction action. The gas concentration at which the solenoid valve is opened is adjustable. For example, when the combustible gas content inside the equipment is maintained at 5% of the set dangerous threshold for combustible gas concentration, the solenoid valve is not activated. When the combustible gas concentration exceeds the threshold of 5%, the solenoid valve is activated.

[0050] Example 2: Figure 9 As shown, the processing unit 16 includes an outer protective chamber 29 fixedly connected to the outside of the ventilation fan 14, an air supply pipe 30 is installed between the two outer protective chambers 29, and a spray tower 31 is installed on the side of the air supply pipe 30 away from the outer protective chamber 29.

[0051] It should be noted that, since the device can be used to store a variety of different kinds of hazardous waste materials, and the volatility of different hazardous waste materials during storage is different, and the danger of volatile matter is also different, when the storage material has no volatility or the volatile matter has no harm, the outside of the air exchange fan 14 can not be equipped with an outer protective cabin 29, and when the volatile matter is dangerous, it needs to be connected to the corresponding backend processing equipment through the outer protective cabin 29. For example, when the hazardous waste stored in the device is a hazardous waste such as a waste lead-acid battery that emits acidic waste gas, a spray tower 31 that provides alkali neutralization needs to be connected. When the device is working, the acidic volatile gas is transmitted to the inside of the spray tower 31 along the gas conveying pipe 30 by the air exchange fan 14. The inside of the spray tower 31 is provided with multiple layers of spray pipes, and a filling layer is arranged between each spray pipe to increase the contact efficiency between the acidic gas and the alkali solution. After sufficient neutralization reaction, the treated safe gas is discharged from the top of the spray tower 31, thereby realizing the safe treatment function of the acidic volatile gas discharged from the device. In addition, if the volatile matter of the storage material is ammonia gas or other alkaline gas, the spray tower 31 is injected with an acidic treatment liquid.

[0052] As shown in Figure 3, the processing piece 16 includes an outer protective cabin 29 fixedly connected to the outside of the air exchange fan 14, and a gas conveying pipe 30 is installed between the two outer protective cabins 29. The side of the gas conveying pipe 30 away from the outer protective cabin 29 is provided with a two-stage activated carbon adsorption device 32. Figure 10

[0053] It should be noted that when the hazardous waste stored in the device is waste oil or other volatile organic compounds (VOCs), a two-stage activated carbon adsorption device 32 needs to be connected. The device is composed of two activated carbon adsorption boxes connected in series. The outer side of the box is provided with a plurality of detachable activated carbon storage drawers. The volatile organic compounds are adsorbed by multiple layers of activated carbon after passing through the activated carbon in the two activated carbon adsorption boxes in sequence, and then the safe gas is discharged. The adsorption capacity of the activated carbon will gradually decrease with the extension of the use time. The activated carbon can be conveniently replaced by twisting the wrench handle on each storage drawer, thereby maintaining the safe treatment function of the device for organic volatile gas.

[0054] Further, as known from the foregoing, when the device is used for storage without volatility or harmful volatile matter, the air exchange fan 14 is only used for daily ventilation. When the storage material has harmful volatile matter, the corresponding volatile gas treatment piece 16 can be connected to the outside of the air exchange fan 14 for targeted treatment of volatile gas. The purpose is to ensure that the main body of the device can store a variety of hazardous waste materials, and at the same time, the device can be flexibly connected to the corresponding volatile gas treatment piece 16, so that it has safety and flexibility when in use. That is, through the structure of the main body plus the flexible connection of the treatment piece 16, the use limitation of the integrated treatment structure for the storage of a variety of hazardous waste materials is avoided, and the waste of single-function tail gas treatment materials is avoided.

[0055] ​In addition, multiple devices storing hazardous waste with the same volatile characteristics can use the same set of backend air pollution control facilities in parallel. After parallel use, the processing capacity of the backend air pollution control facilities is the linear superposition of the required exhaust gas treatment capacity of each device. For example, if one device requires a treatment capacity of 3000 m 3 / h of exhaust gas, and another device requires a treatment capacity of 5000 m 3 / h of exhaust gas, after parallel processing, the preset treatment capacity of the backend air pollution control facilities is 8000 m 3 / h, and devices storing hazardous waste with different volatile characteristics cannot be connected to the same set of facilities, and different backend air pollution control facilities cannot be connected in series. For example, connecting a spray tower 31 and a secondary activated carbon adsorption device 32 in series, the acid mist discharged by the device storing lead-acid batteries will corrode the activated carbon in the backend series.

[0056] After multiple devices are used in parallel, the running power of the air exchange fan 14 after starting follows the following formula:

[0057] ;

[0058] Where P is the power that the current air exchange fan 14 should be turned on, P MAX is the maximum power of the air exchange fan 14, k i is the weight coefficient of the i-th device turning on the air exchange fan 14, c i is the volatile gas concentration detected by the sensor in the i-th device warning unit 15, and c iMAX is the threshold value of the preset gas alarm concentration in the i-th device.

[0059] The above describes one embodiment of the present application in detail, but the content described is only the preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made in accordance with the scope of the present application should still be within the scope of the present application.
