[0001] The utility model relates to the technical field of desulfurization, in particular to a comprehensive desulfurization device. Background Art

[0002] At present, a large amount of harmful gas sulfides that can cause air pollution will be produced during the coal pretreatment process, so it is necessary to use desulfurization equipment to desulfurize and purify these harmful gas sulfides.

[0003] During use, the existing desulfurization device for harmful gas sulfides generated in coal pretreatment usually directly transports the harmful gas sulfides into the interior of the desulfurization tower and treats them by spraying desulfurizer on the top of the tower. The reaction time between the harmful gas sulfides and the desulfurizer is short, resulting in reduced desulfurization efficiency. For this reason, we propose a comprehensive desulfurization device. Utility Model Content

[0004] The utility model aims to provide a comprehensive desulfurization device, which has the advantages of being able to prolong the reaction time of harmful sulfide gas and desulfurizer inside the desulfurization tower, while the desulfurizer and harmful sulfide gas are in uniform contact, thereby improving the desulfurization efficiency. It solves the problem that the existing desulfurization device for harmful gas sulfides generated in coal pretreatment usually directly transports the harmful gas sulfides to the interior of the desulfurization tower during use, and treats them by spraying the desulfurizer on the top of the tower, resulting in a short reaction time between the harmful gas sulfides and the desulfurizer, thereby reducing the desulfurization efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a comprehensive desulfurization device, comprising a base and a desulfurization tower, a spray pump is fixedly installed on the rear surface of the desulfurization tower, an air inlet pipe is fixedly connected to the upper surface of the desulfurization tower near the edge, an air outlet pipe is rotatably installed at the axial position of the upper surface of the desulfurization tower, one end of the air outlet pipe located inside the desulfurization tower is fixedly connected to an inner cylinder, an annular pipe is fixedly installed on the outer surface of the inner cylinder, a plurality of first nozzles and second nozzles are fixedly installed at equal intervals in a circular array on the outer surface of the annular pipe, the first nozzle and the second nozzle are respectively located on the outside and inside of the inner cylinder, a first multi-porous flow equalizing plate is fixedly installed on the outer surface of the inner cylinder near the upper surface, and a second multi-porous flow equalizing plate is fixedly installed on the inner wall of the inner cylinder near the lower surface.

[0006] Preferably, a base is fixedly installed on the lower surface of the desulfurization tower.

[0007] Preferably, the end of the spray pump output pipe is fixedly connected to the outer surface of the annular pipe, and the end of the spray pump input pipe is fixedly connected to the outer surface of the base near the lower surface.

[0008] Preferably, a demister is fixedly installed inside the inner cylinder near the upper surface.

[0009] Preferably, a support frame is fixedly installed on the upper surface of the desulfurization tower, a rotating motor is fixedly installed on the upper surface of the support frame, a cam is fixedly connected to the end of the output shaft of the rotating motor, a lever is fixedly connected to the outer surface of the outlet pipe, and a coil spring is fixedly connected to the outer surface of the lever.

[0010] Preferably, a roller is rotatably mounted on one side of the outer surface of the cam.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model achieves the effect of prolonging the reaction time of harmful sulfide gas and desulfurizer inside the desulfurization tower by arranging a desulfurization tower, an inner cylinder, an annular tube, a first nozzle, a second nozzle, a first porous flow equalizing plate and a second porous flow equalizing plate. At the same time, the desulfurizer and the harmful sulfide gas are in uniform contact, thereby improving the desulfurization efficiency. The harmful sulfide gas generated during the coal pretreatment process enters between the desulfurization tower and the inner cylinder through the air inlet pipe and flows downward, and is evenly distributed between the desulfurization tower and the inner cylinder after passing through the first porous flow equalizing plate, and then contacts, mixes and reacts with the desulfurizer sprayed from the first nozzle. Then, the gas after one spraying reaction enters the inner cylinder, and is evenly distributed inside the inner cylinder after passing through the second porous flow equalizing plate, and then contacts, mixes and reacts with the desulfurizer sprayed from the second nozzle, completing the secondary spraying reaction, and the desulfurized and purified gas is discharged from the air outlet pipe.

[0013] 2. The utility model achieves the effect of uniform distribution of atomized desulfurizer inside the inner cylinder and between the inner cylinder and the desulfurization tower by arranging a rotating motor, a cam, a lever and a coil spring, so that harmful sulfide gas and the desulfurizer are in uniform contact, which is beneficial to the desulfurization and purification of harmful sulfide gas. The rotating motor drives the cam to rotate, and the raised part of the cam periodically contacts the lever. During the contact process, the lever drives the air outlet pipe, the inner cylinder and the annular tube to rotate. When the raised part of the cam and the lever are separated, the compressed coil spring is released, so that the lever is reset, and the air outlet pipe, the inner cylinder and the annular tube are reversely rotated and reset, so that the first nozzle and the second nozzle can rotate and swing back and forth, which is beneficial to the uniform distribution of atomized desulfurizer inside the inner cylinder and between the inner cylinder and the desulfurization tower.

[0014] 3. The utility model converts the sliding friction between the cam and the lever into rolling friction by arranging the roller, thereby reducing friction loss and extending the service life of the lever and the cam. BRIEF DESCRIPTION OF THE DRAWINGS
