Description

Technical Field

[0001] This utility model relates to the field of organic waste gas treatment technology, specifically to an energy-saving, high-efficiency adsorption and desorption device for organic waste gas. Background Technology

[0002] Volatile organic compounds in organic waste gas are called VOCs. In many industries such as coating, printing, shoemaking and chemical production, the production processes of some industrial products are accompanied by the emission of a large amount of volatile organic compound (VOC) waste gas.

[0003] Most existing organic waste gas treatments rely on targeted adsorption and desorption devices to process the waste gas before it can be released back into the atmosphere.

[0004] Most existing adsorption-desorption devices process waste gas through pretreatment, adsorption, and desorption. During pretreatment, filters are usually installed inside the pretreatment tower to remove large particles, dust, and other impurities. After prolonged use, these filters need to be cleaned, but their location inside the treatment tower makes cleaning difficult. Without cleaning, large particles, dust, and other impurities cannot be removed, affecting the subsequent treatment effect.

[0005] Therefore, it is necessary to propose an energy-saving, high-efficiency adsorption and desorption device for organic waste gas. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an energy-saving, high-efficiency adsorption and desorption device for organic waste gas. It effectively removes large particles, dust, and other impurities from waste gas through water mist adhesion, avoiding the limitations of filtration devices. Furthermore, the used water can be purified and reused, thus solving the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: an energy-saving, high-efficiency adsorption and desorption device for organic waste gas, including a pretreatment tower:

[0008] The pretreatment tower has a spiral channel installed inside. A transition block is fixedly connected to the lower middle position inside the pretreatment tower. An atomizing nozzle is installed on the front side of the transition block. There are four sets of transition blocks arranged in a ring. A ring pipe is fixedly connected between the transition blocks.

[0009] A water tank is provided on one side of the pretreatment tower. Inside the water tank, there is a water treatment tank and a water placement tank. Inside the water placement tank, there is a water pump. The upper end of the water pump is connected to a connecting hose. The other end of the connecting hose is fitted with an inlet pipe. The other end of the inlet pipe passes through the pretreatment tower and connects to one of the transition blocks.

[0010] Preferably, the bottom of the pretreatment tower is connected to an inlet pipe, the other end of which is connected to the interior of the water treatment tank. A receiving plate is fixedly connected to the inner wall of the water treatment tank. A snap-fit ​​groove is provided on the receiving plate. A supporting frame is movably connected inside the snap-fit ​​groove. Multiple sets of slots are provided on one side of the supporting frame, and filter plates are inserted into the multiple sets of slots.

[0011] Preferably, a second connecting pipe is fixedly connected between the water treatment tank and the water placement tank, and a second water pump is installed between the second connecting pipes.

[0012] Preferably, a connecting pipe is fixedly connected to one side of the lower end of the pretreatment tower, a dry filter is connected to the other end of the connecting pipe, and an exhaust gas input pipe is fixedly connected to the top of the pretreatment tower.

[0013] Preferably, an activated carbon assembly is provided on one side of the dry filter, and a discharge tower is provided on the other side of the activated carbon assembly.

[0014] Preferably, the dry filter and the activated carbon assembly are connected via an input pipe, and the activated carbon assembly and the discharge tower are connected via an output pipe.

[0015] Preferably, the activated carbon component is connected to a connecting pipe on both the upper and lower sides, and the connecting pipe is connected to an external adsorption component.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This energy-saving high-efficiency adsorption and desorption device for organic waste gas, when pre-treating waste gas, firstly, the waste gas spirals downward through a spiral channel to reduce its velocity until it completely passes through the spiral channel. At this point, water is pumped into the transition block via a water pump, connecting hose, and inlet pipe. The water is then sprayed out by atomizing nozzles on the transition block. The resulting water mist effectively adheres to large particles, dust, and other impurities in the waste gas, thus removing them from the waste gas. This structure effectively slows down the flow rate of the waste gas inside the pretreatment tower, ensuring the adhesion effect of the water mist on large particles, dust, and other impurities. This effectively removes large particles, dust, and other impurities from the waste gas for subsequent adsorption operations, avoiding the poor performance of existing filter plates and other structures after prolonged use. This ensures effective filtration of the waste gas. Furthermore, the water used is collected at the bottom of the pretreatment tower and can be reused for subsequent treatment, effectively saving water resources.

[0018] 2. This energy-saving high-efficiency adsorption and desorption device for organic waste gas treats used water by first sending the water through the discharge pipe into the water treatment tank inside the water tank. The impurities in the water are filtered by multiple sets of filter plates installed inside the water treatment tank. After filtration, the water is sent into the water placement tank through the cooperation of connecting pipe two and water pump two, so that the waste gas can be treated again later. This structure can effectively treat the used water for reuse, thereby achieving the goal of saving water resources. Attached Figure Description
