Description

Technical Field

[0001] The invention relates to the technical field of environmental control, and in particular to an integrated hazardous waste storage device for pollution prevention and control. Background Art

[0002] Industrial solid waste is divided into general industrial waste and hazardous waste. Hazardous waste left in the open air will pollute the environment, so it is necessary to centrally store and treat this type of hazardous industrial solid waste to avoid polluting the environment.

The collecting pipe connecting the exhaust gas treatment box and the waste box absorbs the hazardous waste gas into the exhaust gas treatment box, and then the exhaust gas treatment box treats it. The disadvantages of this technical solution are that, firstly, a waste liquid storage box is arranged along the side of the storage space, but the storage box has a small capacity for storing waste liquid.

When storing non-volatile hazardous waste materials, since the waste gas treatment box of this scheme is located at the top of the waste box and is connected as a whole, the ventilation inside it will still pass through the built-in activated carbon plate and other materials, and this type of adsorption material used as the treatment object has activity restrictions on use, and is easily directly wasted during the storage of non-volatile hazardous waste materials, that is, the integrated treatment structure cannot adapt to the different needs of various hazardous waste material treatments.

[0014] Beneficial effects of the present invention: 1. In the present invention, a lifting seat is installed at the bottom of the outer decoration box, and an inner lining bin is installed on the top of the lifting seat, and a guide groove is set in the middle of the inner lining bin, a collection well is installed at the end of the guide groove, and a grid plate is laid on the top of the inner lining bin. When storing hazardous waste liquid, the staff puts each barrel of hazardous waste liquid into the inner lining bin of the equipment through the external anti-slip platform. When it leaks accidentally, it will flow along the grid plate into the guide groove, and then flow into the collection well from the guide groove. When the leakage is too large, it will fill up the collection well, the guide groove and all the grid plates in the inner lining bin in turn. After the overall storage of the collection well, the guide groove and the grid plate, the ground position inside the equipment is still in an accessible state where hazardous waste liquid has not yet accumulated. That is, the equipment is lifted by the lifting seat, sufficient depth is provided for the collection well and the guide groove, and the grid plate is laid inside the equipment, thereby improving the storage capacity of the equipment for hazardous waste solution with high leakage; Furthermore, by setting multiple partition boards inside the equipment, and installing a partition board at the bottom between two adjacent partition boards, a recording table with a ledger is set on one side of the inner lining bin, and an internal video recorder and an early warning unit are installed on one side of the top inside the equipment, the internal video recorder is connected to the external electric control box, and the electric control box is electrically connected to the monitoring terminal. Then, when a leak occurs inside the equipment, the caregivers around the equipment are reminded by the buzzer in the early warning unit, and the remote monitoring personnel receive the early warning alarm information at the same time, thereby improving the equipment's early warning ability for leakage. Even if the leak is too fast and the leakage amount is large, the staff can contact professional hazardous waste handling staff to enter the equipment, and use the ledger and partition board to quickly grasp the leaked hazardous waste products. The specific information of the leaked hazardous waste can be obtained, so as to quickly formulate a corresponding treatment plan. Its technical advantage lies in that the raised inner lining bin and the laid grid plate enable the equipment to store a large capacity of leaked hazardous waste liquid, providing an effective space for subsequent staff to enter for treatment. The partition board and the recording table can accurately record the hazardous waste information, so that the staff who enter can quickly grasp the specific information of the leaked material, so as to quickly formulate a suitable treatment plan. In other words, in this case, the high capacity of the equipment for hazardous waste liquid and the real-time monitoring and clear recording of hazardous waste liquid information are used to construct an integrated technical solution, which aims to effectively solve the problem of rapid entry and treatment when a large amount of hazardous waste liquid leaks in the equipment, thereby helping to improve the safety of the equipment when it is used.

[0015] 2. In the present invention, by arranging a plurality of partition plates inside the equipment and arranging a partition plate on the top of each partition plate, the equipment can store a variety of hazardous waste materials. At the same time, two ventilation fans are installed at the top of one side of the equipment. Different processing parts can be selected between the two ventilation fans according to the types of hazardous waste materials stored inside. That is, if the stored hazardous waste has no volatiles or the volatiles are harmless, the ventilation fan is used for ventilation. If the stored hazardous waste emits volatile acidic or alkaline gases, the ventilation fan is externally connected to a spray tower, and the ventilation fan is used to transport volatile gases, and the spray tower is built with corresponding alkaline or acidic neutralizing liquid. If the stored hazardous waste emits volatile organic waste gas, the ventilation fan is externally connected to a secondary activated carbon adsorption device, that is, the storage is carried out through the equipment, and then the ventilation fan is connected to the processing equipment suitable for the stored materials. That is, through the flexible connection between the storage equipment and the processing equipment, the equipment can store a variety of types of hazardous wastes while effectively avoiding the ineffective loss of processing materials such as activated carbon in the processing equipment.

[0016] 3. In the present invention, a waterproof exterior box and an interior top layer are installed on the outside and top of the equipment to elevate the equipment to avoid ground corrosion. An integrally welded inner lining bin is installed at the bottom of the equipment. At the same time, a fireproof layer is provided between the equipment exterior box and the interior, and a protective layer is brushed on the inner surface of the inner lining bin in a stacked manner. This allows the equipment to have high protection capabilities against water, fire and corrosion, thereby improving its structural stability during use, avoiding damage to the equipment by the external environment, and thus improving its safety in use. Its purpose is to avoid adding emergency protective equipment by strengthening the overall structural strength of the equipment itself, so as to prevent the problem of failure of such emergency equipment during long-term storage.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Figures 1 to 8 As shown, an integrated hazardous waste storage device for pollution prevention and control includes an exterior decoration box 1, an inner frame is installed inside the exterior decoration box 1, a lifting seat 2 is arranged at the bottom of the inner frame, an inner lining bin 3 is installed on the top of the lifting seat 2, a guide groove 4 is arranged in the middle of the inner lining bin 3, one end of the guide groove 4 is connected to the collection well 5, grid plates 6 are evenly arranged at the bottom of the inner lining bin 3, the grid plates 6 are connected to the guide groove 4, and the lifting seat 2 is used to increase the total liquid storage space of the guide groove 4, the collection well 5 and each grid plate 6; the inner lining bin 3 is evenly installed with partition plates 7 on both sides of the guide groove 4, and an interior decoration top bin 8 is installed on the top, and the interior decoration top bin 8 is installed with a partition plate between the two partition plates 7 Area plate 9, and an internal video recorder 10 is installed on one side of the top, a recording table 11 is set on one side of the inner lining bin 3, and an electric control box 12 is installed on the outside of the exterior box 1. The internal video recorder 10 is used to cooperate with the recording table 11 to quickly locate the stored objects; a fireproof layer 13 is set between the exterior box 1 and the inner lining bin 3, and a protective layer is coated on the inside of the inner lining bin 3. The inner lining bin 3 is welded as a whole; at least one ventilation fan 14 is installed on one side of the top of the interior top bin 8, and an early warning unit 15 is installed on the top. The outside of the ventilation fan 14 is detachably connected to a processing unit 16, and the processing unit 16 is used to cooperate in processing the volatile gas of the stored objects on both sides of the inner lining bin 3; an explosion-proof door 17 is installed on one side of the exterior box 1; It should be noted that the exterior box 1 located outside the equipment and the interior top compartment 8 on the upper part are both waterproof plates to prevent external rainwater from entering the interior of the equipment, preferably polyvinyl chloride waterproof plates; the exterior box 1 is fixedly connected to a warning plate 18 on one side of the explosion-proof door 17 and on the side perpendicular to the side, and the warning plate 18 is used to identify the equipment as a hazardous waste storage facility to avoid external force and pedestrians accidentally contacting; the explosion-proof door 17 (see Figure 1 ) A window 19 is set on the top for the staff to inspect the internal storage situation of the equipment on a daily basis. A handle is set on the top and is equipped with a double-hole lock 20, that is, a double lock that can only be opened by two people at the same time, so as to ensure the supervision when opening and improve the safety of equipment storage; an explosion-proof lamp 21 is installed in the middle of the top of the interior top compartment 8, which is convenient for cooperating with the internal video recorder 10 to maintain long-term uninterrupted monitoring; four lifting ears 22 are installed on the top of the exterior decoration box 1 to facilitate the overall lifting and movement of the equipment.

[0022] like Figure 2 , Figures 5 to 7 As shown, the bottom surface of the collection well 5 is lower than the bottom surface of the guide groove 4, and the height of the lifting seat 2 is not less than 30 cm; The top of the grid plate 6 is flush with the bottom of the explosion-proof door 17, and an anti-slip platform 23 is provided outside the explosion-proof door 17. The total liquid storage volume of the guide groove 4, the grid plate 6 and the collection well 5 is greater than 1 / 3 of the total storage volume; It should be noted that the collection well 5 is located on the side away from the explosion-proof door 17 and is connected to one end of the guide groove 4. At the same time, its depth is greater than the depth of the guide groove 4. The guide groove 4 is used to reduce the contact area between the bottom of the equipment and the ground, reduce the corrosion of the bottom of the equipment by factors such as acidic soil and rainwater, and more importantly, reserve a deeper storage space for the guide groove 4 and the collection well 5 to improve the liquid collection capacity of the guide groove 4 and the collection well 5. A large number of mesh plates 6 are evenly laid on the bottom surface of the inner substrate bin 3. The mesh plates 6 are preferably made of glass fiber to avoid corrosion by stored materials. After leakage, the hazardous waste solution stored in the equipment will be transported to the guide groove 4 along the grid plate 6, and then transferred to the collection well 5 along the guide groove 4. As the leakage amount increases, the collection well 5, the guide groove 4 and the grid plate 6 will be filled up in turn. However, due to the use of the lifting seat 2 and the strong total liquid storage capacity of these 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 the capacity of a single tank of hazardous waste solution in the equipment or 1 / 3 of the total liquid storage amount in the equipment, and the two take the larger value. In the event of a serious leakage accident with a high leakage amount, the top of the grid plate 6 can still be kept in a state where treatment personnel can enter and settle, thereby greatly improving the equipment's ability to resist sudden leakage of hazardous waste solutions. The purpose is to enable the equipment to maintain the ability to provide convenient entry for treatment personnel when facing a large amount of hazardous waste solution leakage, thereby improving the storage safety of the equipment and avoiding the situation where a large volume of hazardous waste solution cannot be treated when it leaks; In addition, since the equipment uses a lifting seat 2 and the height of the explosion-proof door 17 is flush with the height of the internal mesh plate 6, an anti-slip platform 23 is set up outside to ensure that all kinds of hazardous waste can be conveniently transported to the inside of the equipment. The lifting seat 2 is made of high-strength structural steel, which increases the overall strength of the equipment while facilitating the overall lifting and transfer by the lifting ears 22.

[0023] like Figures 2 to 4 As shown, the side height of the inner lining bin 3 is 1.5 meters, the inner lining bin 3, the guide groove 4 and the collection well 5 are welded as a whole by steel, the inner frame also includes a side beam 24 arranged on the side of the outer decoration box 1, a top beam 25 is installed between the inner top of the outer decoration box 1 and the interior decoration top bin 8, and the fireproof layer 13 is arranged between the two sides and the top of the inner side of the outer decoration box 1; The protective layer includes an anti-corrosion paint 26 adjacent to the outer side of the inner lining bin 3, two layers of anti-seepage paint 27 are coated on the outer side of the anti-corrosion paint 26, and reinforcing cloth 28 is installed in the two adjacent layers between the inner lining bin 3 and the outermost anti-seepage paint 27; It should be noted that the inner lining bin 3, the guide trough 4 and the collection well 5 are all welded together with carbon steel to form an integrated ship-shaped lining, thereby improving the sealing performance of the equipment during use. After the waste liquid leaks, it cannot penetrate to the bottom surface through this integrated structure, thereby causing soil and groundwater pollution in the area; on this basis, a fireproof layer 13 is filled and laid on the inner side of the exterior box 1 relying on the barrier space of the inner frame. The fireproof layer 13 is preferably made of rock wool sandwich panels. In addition, the inner side of the ship-shaped lining is coated with glass cloth, anti-corrosion asphalt paint, glass cloth, epoxy resin anti-seepage paint, glass cloth and epoxy resin anti-seepage paint. The coating sequence of the paint sets up a protective layer, wherein the reinforcing cloth 28 is preferably glass fiber cloth. When the equipment is in use, the fireproof layer 13 can prevent internal spontaneous combustion and burning through the exterior decoration box 1 to cause leakage. The anti-seepage paint 27 located on the top layer of the lining can prevent the hazardous liquid from leaking outward, and the anti-corrosion paint 26 on the bottom layer can be used to prevent leakage caused by external corrosion inward. The purpose is to improve the corrosion resistance, seepage resistance and fire resistance of the equipment through the integrally welded lining and multi-layer protective layers, and structurally avoid external interference from causing substantial damage to the equipment that may cause hazardous waste leakage, thereby improving the risk resistance of the equipment during use and improving safety of use.

[0024] like Figure 2 and Figure 8 As shown, the internal video recorder 10 is located in the middle of the top of the interior top compartment 8 away from the explosion-proof door 17, and the recording table 11 is installed on the side close to the explosion-proof door 17. The internal video recorder 10 and the early warning unit 15 are electrically connected to the electric control box 12. The electric control box 12 has a built-in signal transceiver module and is connected to the remote monitoring terminal. The partition plate 9 is used to identify the type of hazardous waste materials stored between the two adjacent partition plates 7 below; It should be noted that the partition plate 7 is used to block the inner substrate bin 3 inside the equipment into multiple storage areas. A partition plate 9 is installed at the top of each storage area for each storage area. The partition plate 9 is used to record the types of hazardous waste stored in each storage area. The recording table 11 summarizes the detailed information such as the entry and exit time and storage volume of the stored objects in each storage area to record the materials stored in the equipment in detail; the internal video recorder 10 and the early warning unit 15 cooperate with the explosion-proof lamp 21 to monitor the real-time storage status of hazardous waste inside the equipment. When a leak occurs and triggers the alarm system of the early warning unit 15, the corresponding information of the internal video recorder 10 and the early warning unit 15 is received by the signal transceiver module in the electric control box 12 connected thereto and sent to the remote end, which is received by the remote monitoring terminal and performs subsequent response processing; That is, the storage objects are clearly divided into stacking positions by the partition board 7 and the partition board 9 to prevent the mixing of different types of hazardous waste materials and avoid the risk of the mixing of different types of hazardous wastes causing the mutual reaction during storage to generate secondary hazards. The recording table 11 then records the internal storage objects in detail, and the internal video recorder 10 is used to monitor the storage status in real time. The purpose is to record and monitor the storage objects in the equipment in detail after they are isolated and placed. When the storage objects leak, it can be known through remote image monitoring. After the treatment personnel arrive at the scene, they can quickly know all the information of the leaked substances with the help of the recorded information on the partition board 9 and the recording table 11, so as to speed up the provision of appropriate treatment methods for the leaked objects and speed up the rapid response capability of the equipment in the face of sudden leaks. In addition, detailed information recording can also avoid erroneous transfer during daily access. Furthermore, an external video recorder is installed on one side of the top of the explosion-proof door 17 of the exterior decoration box 1 to cooperate with the internal video recorder 10 for information comparison.

[0025] The early warning unit 15 has a built-in combustible gas concentration sensor, a volatile organic compound concentration sensor, an acid mist sensor and a buzzer. The early warning unit 15 is electrically connected to the electric control box 12. The electric control box 12 has a built-in solenoid valve, and the solenoid valve is electrically connected to the ventilation fan 14. It should be noted that the solenoid valve is an induction valve and the early warning unit 15 integrates multiple sensors to adapt to the storage needs of various types of hazardous waste materials of the equipment. When a corresponding leakage occurs inside the equipment, the early warning unit 15 immediately triggers the early warning information and alerts the staff through a buzzer. The early warning information is sent to the control center through the signal transmission module inside the electric control box 12, so that the control center can contact professional processing personnel in time for processing; preferably, when the sensors in the early warning unit 15 are in the normal concentration range, the electric control box 12 controls the solenoid valve to be in a closed state, and the ventilation fan 14 does not work. When a sensor in the early warning unit 15 is triggered, the electric control box 12 starts the solenoid valve, and the ventilation fan 14 performs a pumping action, and the gas concentration for opening the solenoid valve is adjustable. For example, when the combustible gas content inside the equipment is maintained at 5% of the set combustible gas concentration danger threshold, the solenoid valve is not started. When the combustible gas concentration exceeds the threshold of 5%, the solenoid valve is started.

[0026] Embodiment 2: Fig. 9 As shown, the treatment 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; It should be noted that since the equipment can be used to store a variety of different types of hazardous waste materials, and the volatility of different hazardous waste materials during storage is different, and the hazardousness of volatiles is also different, when the stored materials are non-volatile or the volatiles are harmless, the outer protective chamber 29 does not need to be installed on the outside of the ventilation fan 14. When the volatiles are hazardous, it is necessary to connect the pipeline through the outer protective chamber 29 to the corresponding back-end processing equipment. For example, when the hazardous waste materials stored inside the equipment are hazardous wastes that emit acidic waste gas, such as waste lead-acid batteries, it is necessary to connect to the alkaline solution supply. When the neutralizing spray tower 31 is working, the ventilation fan 14 transmits the acidic volatile gas along the gas pipe 30 to the inside of the spray tower 31. A multi-layer spray pipe is arranged inside the spray tower 31, and a filling layer is arranged between each spray pipe to increase the contact efficiency between the acidic gas and the alkaline 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 equipment; in addition, if the volatile matter of the stored material is an alkaline gas such as ammonia, the acidic treatment liquid is injected into the spray tower 31.

[0027] Embodiment 3: Fig.10 As shown, the treatment element 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 secondary activated carbon adsorption device 32 is installed on the side of the air supply pipe 30 away from the outer protective chamber 29; It should be noted that when the hazardous waste materials stored inside the equipment are waste engine oil and other volatile organic compounds (VOCs), a secondary activated carbon adsorption device 32 is connected. The device is composed of two activated carbon adsorption boxes connected in series, and a plurality of detachable activated carbon storage drawers are arranged on the outside of the box. After the volatile organic matter passes through the activated carbon in the two activated carbon adsorption boxes in turn, it will be intercepted and adsorbed by multiple layers of activated carbon, and then the safe gas will be 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 plum blossom handle on each storage drawer, so as to maintain the equipment's safe treatment function for volatile organic gases.

[0028] Furthermore, it can be seen from the foregoing that when the equipment is storing non-volatile or non-hazardous volatiles, the ventilation fans 14 are only used for daily ventilation, and when hazardous volatiles are present in the stored materials, targeted volatile gas treatment can be carried out by externally connecting processing components 16 to the outside of the two ventilation fans 14. The purpose is to ensure that the main body of the equipment can store a variety of hazardous wastes while allowing the equipment to flexibly connect corresponding volatile gas processing components 16, so that it has both safety and flexibility when used. That is, through the structural form of the main body plus the flexible docking processing component 16, the use restrictions of the integrated processing structure when storing a variety of hazardous wastes are avoided, and the ineffective waste of single-function exhaust treatment materials is avoided.

[0029] In addition, multiple devices storing hazardous wastes with the same volatile characteristics can be connected in parallel to use the same set of back-end air pollution control facilities. After parallel use, the treatment capacity of the back-end air pollution control facilities is the linear superposition of the waste gas treatment capacity required by each device. For example, if one of the devices requires 3000m 3 / h exhaust gas processing capacity, the other equipment needs 5000m 3 / h exhaust gas processing capacity. After the two are processed in parallel, the preset exhaust gas processing capacity of the back-end air pollution control facility is 8000m 3 / h, and the equipment storing hazardous wastes with different volatility characteristics cannot be incorporated into the same system, nor can different rear-end air pollution control facilities be used in series, such as connecting the series spray tower 31 and the secondary activated carbon adsorption device 32 in series, and the acid mist discharged by the equipment storing waste lead-acid batteries will corrode the activated carbon in series at the rear end; Among them, after the early warning unit 15 is used in parallel with multiple devices, the operating power of the ventilation fan 14 after starting follows the following formula: ; Wherein, P is the power that the ventilation fan 14 should be turned on at present, P MAX is the maximum opening power of the ventilation fan 14, k i is the weight coefficient for turning on the ventilation fan 14 for the i-th device, c i is the concentration of volatile gas detected by the sensor in the i-th equipment warning unit 15, c iMAX is the gas alarm concentration threshold preset in the i-th device.

[0030] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention.
