Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, to a hazardous waste storage waste gas collection and treatment device. Background Art

[0002] Hazardous waste storage refers to the storage of hazardous waste. Different types of hazardous waste must be stored separately to prevent incompatible substances from coming into contact and reacting. Liquid hazardous waste refers primarily to hazardous liquid wastes. These typically possess one or more hazardous properties, such as corrosiveness, toxicity, flammability, reactivity, or infectivity. If improperly handled, they can pose a serious threat to the environment or human health.

[0003] When storing liquid hazardous waste, it needs to be kept sealed to prevent the gases emitted from it from escaping. Existing storage devices are not convenient for storing stored liquid waste in a sealed manner. At the same time, most storage devices are externally connected to exhaust gas collection and treatment devices and are not equipped with dedicated exhaust gas collection and treatment mechanisms. This results in the inability to effectively treat exhaust gas during equipment transportation. Harmful gases emitted by some liquid waste can easily accumulate, causing increased pressure inside the storage mechanism. If not effectively purified, it can easily lead to dangers such as explosions in storage tanks. In view of this, we propose a hazardous waste storage exhaust gas collection and treatment device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a hazardous waste storage and waste gas collection and treatment device to solve the technical problems that current storage equipment is inconvenient for sealed storage of liquid waste, and harmful waste gas cannot be purified in a timely and effective manner, causing safety hazards.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a hazardous waste storage and waste gas collection and treatment device, comprising a panel and a retaining frame, wherein seam strips are distributed in a circular array at the front end of the retaining frame, and an air hood is provided between the seam strips, an assembly port is provided at the rear end of the retaining frame, and an air collecting cylinder is provided in the assembly port, and a wind tube is provided on the air collecting cylinder, an arc port is provided on the inner side of the air hood, and a storage tank is fixed between the arc ports of adjacent air hoods, the panel is rotatably installed at the front end of the storage tank by a rotating shaft, a first arc groove and a second arc groove are respectively provided at the upper and lower ends of the inner side of the panel, and a sealing gasket is provided at one end inside the first arc groove.

[0006] When the utility model is used, the liquid injection pipeline is connected to the loading port through the operating port of the second arc groove, and the liquid waste is injected into the corresponding storage tank. After the feeding is completed, the material is separated, and then the panel structure is rotated to move the loading port in the second arc groove to the sealing gasket. The loading port is blocked by the sealing gasket structure to achieve closed treatment, so that the harmful gas generated by the liquid waste in the storage tank will not escape to the outside, ensuring the safety of storage. When unloading, the cover at the discharge port is opened through the operating port of the first arc groove to discharge the liquid waste to the outside. This device can store different liquid wastes through the independent storage structure design, and the storage tank can be sealed by rotating the panel structure to prevent the harmful gas inside it from leaking. Its independent structural design does not connect with the external pipeline, and it is horizontal. The structural design facilitates transportation and reduces the difficulty of transshipment. When the panel is rotated to achieve closure, the harmful gas generated by the liquid waste in the storage tank flows through the air groove to the corresponding air hood interface. The harmful gas enters the air hood and is filtered through three filtering mechanisms. The corresponding filter material can be selected according to the harmful gas generated to achieve purification, neutralization and removal of the corresponding harmful substances in the harmful gas. The gas is then discharged into the gas collecting cylinder through the tail pipe and discharged outward through the wind tube. A fan is built into the wind tube to guide the gas to accelerate the flow. Through the design of the panel structure, the storage mechanism is equipped with a gas circulation and purification passage and structure to avoid the increase of air pressure in the sealed storage tank due to the generation of harmful gas, ensure the safety of storage, and effectively treat the harmful gas guided for discharge.

[0007] Preferably, a loading port and a loading port are respectively provided on the upper and lower sides of the front end of the storage tank, and a sealing cover is provided at the loading port.

[0008] Preferably, a docking port is provided on the inner side of the arc opening of the air vent hood, and the docking port is connected to one end inside the air vent hood.

The utility model designs a retaining frame, wherein an air hood is fixed between the seam strips of the retaining frame, and a storage tank is installed in the inner arc opening of the connected air hood. The three storage tanks are designed horizontally, which is convenient for independent storage of liquid waste and convenient for transportation and other operations. The injection pipeline is connected to the loading port through the operation port of the second arc groove, and the liquid waste is injected into the corresponding storage tank. After the feeding is completed, the material is separated, and then the panel structure is rotated to move the loading port in the second arc groove to the sealing gasket. The loading port is blocked by the sealing gasket structure to achieve closed treatment, so that the harmful gas generated by the liquid waste in the storage tank will not escape to the outside, ensuring the safety of storage. When unloading, the cover at the unloading port is opened through the operation port of the first arc groove to discharge the liquid waste to the outside. The device can store different liquid wastes through the independent storage structure design, and the storage tank can be sealed by rotating the panel structure to prevent the harmful gas inside it from leaking. Its independent structural design is not connected to the external pipeline. The horizontal structural design is convenient for transportation and reduces the difficulty of transportation.

[0015] 2. The utility model also designs a panel. When the panel is rotated to achieve closure, the harmful gas generated by the liquid waste in the storage tank flows through the air groove to the corresponding air hood interface. The harmful gas enters the air hood and is filtered through three filtering mechanisms.
