Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a purification tower for acidified waste gas from vegetable oil soap residue. Background Technology

[0002] Acidified oil refers to oil obtained by acidifying soapstock, a byproduct of oil refining. Essentially, acidified oil is a fatty acid-containing oil, containing pigments and unacidified triglycerides, diglycerides, monoglycerides (neutral oils), and other components. The fatty acids here are long-chain fatty acids, generally with carbon chains between 12 and 24, predominantly between 16 and 18. Depending on the source of the oil, acidified oil exhibits different distributions of saturated and unsaturated carbon chains.

[0003] In existing technologies, such as the vegetable oil soap residue acidification waste gas purification tower disclosed in patent publication number CN219091608U, the following components are included: a gas collection hood, which has a structure that is wider at the bottom and narrower at the top; a connecting pipe, which has an L-shaped structure consisting of a first sub-pipe and a second sub-pipe; a receiving space provided at the corner of the connecting pipe; liquid nitrogen, which is placed in the receiving space; an alkaline scrubbing tower located at the output end of the connecting pipe; a packed absorption tower located at the output end of the alkaline scrubbing tower; and an activated carbon adsorber fan located at the output end of the packed absorption tower, at the end of the waste gas purification path. The vegetable oil soap residue acidification waste gas purification tower of this utility model has a simple structure, is suitable for purifying vegetable oil soap residue acidification waste gas, and the purified waste gas can be directly discharged.

[0004] The waste gas produced by the acidification of vegetable oil soap residue is highly destructive. When treating this type of waste gas, adsorption is used to adsorb impurities inside the waste gas. However, this method has the problem of limited purification effect, and a large number of impurities and harmful gases remain inside the waste gas. Therefore, the above problems need to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a purification tower for acidified waste gas from vegetable oil soap residue, which has excellent purification effect on waste gas.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a purification tower for acidified waste gas from vegetable oil soap residue, comprising a purification tower, a locking block fixedly connected inside the purification tower, an activated carbon mesh locked inside the locking block, activated carbon disposed inside the activated carbon mesh, a three-way pipe fixedly connected inside the purification tower, a nozzle fixedly connected to the bottom of the three-way pipe, a washing tank fixedly connected to one end of the three-way pipe, a cleaning liquid disposed inside the washing tank, a motor fixedly connected to the bottom of the washing tank, a drive shaft fixedly connected to the output end of the motor, a stirring blade fixedly connected to the outside of the drive shaft, a pump body fixedly connected to the middle of the three-way pipe, a heating zone fixedly connected to the inner wall of the purification tower, an electric heating wire disposed inside the heating zone, a gas pipe fixedly connected to the outside of the purification tower, and an outlet opened at the top of the purification tower.

[0007] By adopting the above technical solution, the acidification waste gas from vegetable oil soap residue enters the interior of the purification tower through a gas pipeline. The waste gas rises from the bottom of the purification tower, securing the activated carbon mesh inside the tower with clips. As the waste gas rises, it enters the activated carbon mesh, where the activated carbon adsorbs impurities. The cleaning liquid is stored inside the washing tank. The starter motor drives the agitator blades via the drive shaft, thus mixing the cleaning liquid inside the washing tank and preventing sedimentation. The pump is then activated, pumping the contents of the washing tank... The cleaning fluid is drawn into the interior of the three-way pipe, which extends into the purification tower. The cleaning fluid is sprayed out through nozzles and drips onto the exhaust gas, thereby reducing dust and purifying impurities within the exhaust gas. The heating zone is located at the top of the purification tower and is heated by heating wires. When exhaust gas enters the heating zone, the high temperature inside the zone kills harmful gases. The exhaust gas is then discharged through the outlet. This process, through adsorption, dust reduction, and sterilization, enhances the purification effect of the exhaust gas.

[0008] A further feature of this invention is that a fan is fixedly installed inside the outlet, and a grille is fixedly connected inside the outlet.

[0009] By adopting the above technical solution, when the exhaust outlet discharges waste gas, the fan is activated to exhaust air. The purified waste gas is discharged from the interior of the purification tower through the airflow, thereby improving the emission efficiency of waste gas. In addition, the grille covers the exhaust outlet to prevent external impurities from entering the interior of the purification tower through the exhaust outlet.

[0010] A further feature of this invention is that a fan bracket is fixedly installed inside the outlet, and the fan is fixed inside the fan bracket.

[0011] By adopting the above technical solution, the fan is fixed inside the outlet by the fan bracket, which improves the stability of the fan during operation.

[0012] A further feature of this invention is that a flange is fixedly installed inside the outlet, and an exhaust pipe is provided inside the flange.

[0013] By adopting the above technical solution, the exhaust pipe is fixed inside the outlet through a flange, and one end of the exhaust pipe extends to the outside of the factory building, so that the purified exhaust gas can be discharged to the outside of the factory building.

[0014] A further feature of this invention is that a lifting ring is attached to the middle of the exhaust pipe, and a bolt is threaded into the internal part of the lifting ring.

[0015] By adopting the above technical solution, the middle part of the exhaust pipe is hoisted by a lifting ring, and the lifting ring is fixed to the ceiling of the factory building by bolts, thereby supporting the exhaust pipe.

[0016] A further feature of this invention is that the number of the lifting rings is multiple, and the inner walls of each of the multiple lifting rings are fixedly connected with cotton pads.

[0017] By adopting the above technical solution, the cotton pad is placed in the gap between the lifting ring and the exhaust pipe, thereby preventing the exhaust pipe from being worn.

[0018] A further feature of this invention is that a drain pipe is fixedly connected to the bottom of the purification tower, and a wastewater tank is fixedly connected to one end of the drain pipe.

[0019] By adopting the above technical solution, the cleaning fluid after dust suppression will enter the interior of the wastewater tank through the drain pipe, and the cleaning fluid will be collected in the wastewater tank.

[0020] A further feature of this invention is that a drain pipe is fixedly connected inside the wastewater tank, and a valve is installed inside the drain pipe.

[0021] By adopting the above technical solution, opening the valve allows the used cleaning fluid to be discharged outside the wastewater tank.

[0022] A further feature of this invention is that an inlet pipe is fixedly connected inside the washing tank, and a sealing plug is provided inside the inlet pipe.

[0023] By adopting the above technical solution, when it is necessary to inject cleaning fluid into the washing tank, the cleaning fluid is injected into the washing tank through the inlet pipe.

[0024] A further feature of this invention is that the number of nozzles is several, and the several nozzles are divided into two groups.

[0025] By adopting the above technical solution, two sets of nozzles are respectively set at both ends of the three-way pipe, and the two sets of nozzles are used to treat the dust in the exhaust gas inside the purification tower.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a purification tower, a locking block, an activated carbon mesh, a three-way pipe, a nozzle, a washing tank, a motor, a drive shaft, a stirring blade, a pump body, a heating zone, a heating wire, and a gas pipeline, allows the acidification waste gas from vegetable oil soap residue to enter the purification tower through the gas pipeline. The waste gas surges upward through the bottom of the purification tower, securing the activated carbon mesh inside the tower via the locking block. As the waste gas surges upward, it enters the activated carbon mesh, where the activated carbon adsorbs impurities. The cleaning liquid is stored inside the washing tank. A starter motor drives the stirring blade via the drive shaft, thereby mixing the cleaning liquid inside the washing tank. To prevent the cleaning solution from settling, the pump is started, drawing the cleaning solution from the washing tank into the three-way pipe. The three-way pipe extends into the purification tower, where the cleaning solution is sprayed out through nozzles. The cleaning solution drips down and comes into contact with the exhaust gas, thus reducing dust and purifying impurities. The heating zone is located at the top of the purification tower and is heated by heating wires. When exhaust gas enters the heating zone, the high temperature inside the zone kills harmful gases. The exhaust gas is then discharged through the outlet. This process, through adsorption, dust reduction, and disinfection, enhances the purification effect of the exhaust gas.

[0028] 2. This utility model, through the arrangement of a fan, grille, flange, exhaust pipe, lifting ring, bolts, and cotton pad, allows the fan to be activated when exhausting waste gas, enabling the purified waste gas to be discharged from the interior of the purification tower through the airflow, thereby improving the emission efficiency of waste gas. The grille covers the exhaust outlet to prevent external impurities from entering the interior of the purification tower through the exhaust outlet. The exhaust pipe is fixed inside the exhaust outlet by the flange, with one end extending to the outside of the factory building, allowing the purified waste gas to be discharged outside the factory building. The middle part of the exhaust pipe is suspended by a lifting ring, which is fixed to the ceiling of the factory building by bolts, thereby supporting the exhaust pipe. Attached Figure Description
