Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to a flue gas desulfurization and dust removal spray device. Background Art

[0002] Flue gas desulfurization is a technology used to reduce the sulfur dioxide content in flue gas. Sulfur dioxide is one of the main pollutants produced when burning fossil fuels. It can cause acid rain, air pollution and health problems. The principle of flue gas denitrification is to convert sulfur dioxide into harmless compounds through chemical reactions, thereby reducing the pollution caused by its emission into the atmosphere. This process is usually carried out in a flue gas desulfurization device. When the flue gas passes through the desulfurization device, it will come into contact with the desulfurization agent sprayed by the device and react to form sulfates or sulfites. These compounds can then be collected and processed. In addition, when spraying the denitrification agent, it can also have a certain dust removal effect.

[0003] However, conventional flue gas desulfurization devices often have spray dead spots during dust removal spraying, resulting in insufficient contact between the flue gas and the desulfurizer, causing a large amount of sulfur dioxide or sulfide to remain in the flue gas after desulfurization.

[0004] In view of this, a flue gas desulfurization and dust removal spray device is proposed. Utility Model Content

[0005] The utility model aims to solve the problem that a flue gas desulfurization spray device has a spray dead angle during operation, resulting in insufficient contact between flue gas and desulfurizer, and provides a flue gas desulfurization and dust removal spray device.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a flue gas desulfurization and dust removal spray device, comprising a bracket, a working chamber fixedly mounted on the bracket and two spray chambers arranged in the working chamber, and also comprising: a spray component, the spray component is arranged inside the spray chamber, the spray component comprises a rotating pipe rotatably mounted on the spray chamber and two branch pipes opened on the rotating pipe, both of the two branch pipes are connected with a spray pipe, a plurality of spray heads are arranged on the spray pipe, and the spray component is used for spraying a desulfurizer for desulfurization operation; a rotating component, the rotating component is arranged on one side of the working chamber, the rotating component comprises a rotating ring fixedly mounted on the rotating pipe and a pulley fixedly mounted on the rotating ring, the pulleys arranged on the two spray chambers are connected by a transmission belt, and the rotating component is used to drive the spray component to rotate.

[0007] Furthermore, an air inlet and an air outlet are respectively provided at both ends of the working chamber, and the two spray chambers are connected by a ventilation pipe. The spray chamber at the air inlet is provided with an air inlet pipe connected to the air inlet, and the spray chamber at the air outlet is provided with an air outlet pipe connected to the air outlet.

[0008] Furthermore, two connecting rods are fixedly connected to the rotating tube, and the two connecting rods are fixedly connected to the two spray pipes.

[0009] Furthermore, a motor is fixedly installed on one side of the working chamber near the air inlet, a gear is fixedly connected to the output end of the motor, and a plurality of teeth meshing with the gear are provided on the pulley of the spray chamber at the air inlet.

[0010] Furthermore, a mounting rod is fixedly installed on one side of the spray bin, a mounting ring is fixedly connected to the mounting rod, and the mounting ring is rotatably connected to the swivel.

[0011] Furthermore, a liquid inlet pipe for conveying desulfurizing agent to the spraying component is fixedly connected to the mounting rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The flue gas desulfurization and dust removal spray device provided by the utility model is rotatable, so that when the flue gas passes through the spray chamber, the contact effect between the flue gas and the desulfurizer can be improved under the rotation of the spray component, avoiding the problem of spray dead angles and improving the desulfurization effect;

[0014] 2. The flue gas desulfurization and dust removal spray device provided by the utility model improves the desulfurization effect of the device by setting two spray chambers, so that the flue gas passing through the spray chamber at the air inlet can enter the spray chamber at the air outlet for desulfurization operation if it is not completely desulfurized;

[0015] 3. The flue gas desulfurization and dust removal spray device provided by the utility model is configured with a pulley and a transmission belt so that when one of the two rotating rings rotates, the other can be driven to rotate. That is to say, when the rotating pipe of one spray chamber drives the spray head to rotate, the rotating pipe of another spray chamber will also drive the spray head to rotate, thereby reducing the waste of resources of power components.
