Description

Technical Field

[0001] The utility model relates to the field of storage, in particular to a storage device for hazardous waste before treatment. Background Art

[0002] In existing chemical production, a large amount of hazardous waste is generated. Although these hazardous wastes have greatly reduced their corrosiveness or toxicity after corresponding chemical reactions, they still have the effect of hurting people. In order to treat these hazardous wastes, relevant purification devices are usually used to batch purify the hazardous wastes. In order to ensure that the hazardous wastes will not hurt people due to exposure to the outside world during concentration, the wastes are usually put into a special storage device for hazardous waste before treatment for sealed storage.

[0003] The existing storage device for hazardous waste before treatment usually puts the hazardous waste into the waste storage tank through the feeding port of the waste storage tank (the feeding cover is immediately closed and sealed after feeding). The hazardous waste is separated into solid and liquid through the internal solid-liquid separation plate of the waste storage tank, reducing the possibility of its continuous chemical reaction, so as to ensure the safety of the waste storage tank (in order to ensure that the waste liquid leaking from the waste will not pollute the ground environment, a check valve is usually installed at the waste liquid discharge port to discharge the waste liquid in batches and uniformly).

[0004] Because the hazardous waste is in the sealed environment of the waste storage tank, the toxicity of the exhaust gas inside it will become stronger and stronger. When the operator opens the discharge port, it is very likely to be injured by the leaked high-concentration exhaust gas. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing storage device for hazardous waste before treatment cannot timely treat the exhaust gas generated in the waste storage tank.

A gas one-way valve is arranged at the air outlet end of the air outlet, and both the gas one-way valve and the water seal purification tank are connected to the air port of the air extraction device through corrosion-resistant pipelines.

[0007] As an improvement, a detachable dust-proof net is arranged at the air inlet end of the air outlet.

[0008] As an improvement, the detachable dust-proof net is connected to the air inlet end of the air outlet through a bolt structure.

[0009] As an improvement, the solid-liquid separation plate is an inclined plate. A discharge port located at the bottom end of the solid-liquid separation plate is provided on the side wall of the waste storage tank. A sealing plate for sealing the discharge port is provided inside the discharge port, and a corrosion-resistant sealing ring is provided on the outer wall of the sealing plate.

[0010] As an improvement, the sealing plate is connected to the side wall of the discharge port through a hinge, and the sealing plate is connected to the side wall of the waste storage tank through a pin structure.

[0012] As an improvement, the air extraction device is connected to the outer wall of the waste storage tank through a bolt structure, and the water seal purification tank and the outer wall of the waste storage tank are connected by welding.

[0013] The advantages of the present utility model compared with the prior art are as follows: The device extracts the hazardous waste gas in the waste storage tank from the air outlet through the air extraction device and purifies it through the water seal purification tank, ensuring that the waste gas in the waste storage tank does not harm people and does not pollute the air.

Detailed Embodiments

[0020] The following further elaborates on the present utility model in conjunction with the accompanying drawings.

[0021] As shown in the attached Figure 1 , 3 , and Figure 5, it includes a waste storage tank 1. Inside the waste storage tank 1, there is a solid-liquid separation plate 2. At the bottom of the waste storage tank 1, there is a check valve 3 that closes the liquid outlet. The solid-liquid separation plate 2 and the waste storage tank 1 are of an integrated structure, thereby ensuring the stability of the solid-liquid separation plate 2 and preventing the waste from collapsing the solid-liquid separation plate 2. After the hazardous waste enters the waste storage tank 1, the liquid in the hazardous waste can leak through the solid-liquid separation plate 2 into the liquid storage tank below the solid-liquid separation plate 2, avoiding chemical reactions of the hazardous waste in the tank.

[0022] The solid-liquid separation plate 2 is an inclined plate (this inclined surface facilitates the removal of waste). On the side wall of the waste storage tank 1, there is a discharge port 11 located at the bottom end of the solid-liquid separation plate 2. Inside the discharge port 11, there is a sealing plate 12 for sealing the discharge port 11. On the outer wall of the sealing plate 12, there is a corrosion-resistant sealing ring 13. The sealing plate 12 is connected to the side wall of the discharge port 11 through a hinge, and the sealing plate 12 is connected to the side wall of the waste storage tank 1 through a pin structure; the corrosion-resistant sealing ring 13 is sleeved on the outer wall of the sealing plate 12, the sealing plate 12 is inserted into the discharge port 11, and the upper side of the sealing plate 12 is connected to the upper side of the discharge port 11 using a hinge, enabling the sealing plate 12 to rotate around the hinge. The pin hole at the bottom of the sealing plate 12 is aligned with the pin hole at the bottom of the waste storage tank 1, and a pin is inserted for fixation.

[0023] As shown in the attached Figure 2 , 3 , and Figure 4, on one side of the top of the waste storage tank 1, there is a gas extraction device 4. The gas extraction device 4 includes an air outlet 41 at the top end of the waste storage tank 1, a water seal purification tank 42 on one side of the waste storage tank 1, and an air extraction device 43 for extracting the exhaust gas inside the waste storage tank 1. The water seal purification tank 42 is connected to the outer wall of the waste storage tank 1 by welding, making the water seal purification tank 42 and the waste storage tank 1 an integrated structure through welding, reducing the number of parts during disassembly.

[0024] At the air outlet end of the air outlet 41, there is a gas check valve 44. The gas check valve 44 and the water seal purification tank 42 are both connected to the air inlet of the air extraction device 43 through corrosion-resistant pipelines. The gas check valve 44 is inserted into the air outlet 41 and sealed using airtight glue or other items to prevent the exhaust gas from flowing back through the gas check valve 44.

[0025] A detachable dust-proof net 45 is provided at the air inlet end of the air outlet 41. The detachable dust-proof net 45 is connected to the air inlet end of the air outlet 41 through a bolt structure. The detachable dust-proof net 45 can prevent floating objects such as sand and dust from entering the air extraction device 43 and extend the service life of the air extraction device 43.

[0026] An air vent extension pipe 421 connected to the air inlet of the water seal purification tank 42 is provided inside the water seal purification tank 42. Through the air vent extension pipe 421, the purification degree of the gas after entering the water seal purification tank 42 is ensured.

[0027] When the present utility model is specifically implemented, the hazardous waste is put into the waste storage tank 1 from the feeding port above the waste storage tank 1. Immediately after the feeding is completed, the feeding cover is closed. The liquid in the hazardous waste passes through the filtration of the solid-liquid separation plate 2 and enters the waste liquid tank below the solid-liquid separation plate 2 (after accumulating a certain amount, open the on-off valve 3 to drain the waste liquid into the corresponding liquid storage box); start the extraction device 4 to extract the waste gas in the hazardous waste storage tank 1 from the air outlet 41 to the water seal purification tank 42. Through the purification of the purification liquid in the water seal purification tank 42, the gas is made harmless and then discharged (to protect the nearby air from pollution); after the waste storage tank 1 is full, remove the pin, rotate the sealing plate 12 around the hinge to open it, take out the hazardous waste, and then insert the pin into the pin hole of the sealing plate 12 again for fixation.

[0028] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
