Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of odor recovery, in particular to an odor recovery explosion-proof system structure. Background Art
[0002] The papermaking process is divided into two parts: pulping and papermaking. Pulping is the process of using chemical cooking, mechanical grinding or a combination of the two to different degrees to dissociate plant fiber raw materials into natural pulp, and then bleaching it into bleached pulp. Papermaking is the process of beating pulp, adding glue and filler, and then making paper through a paper machine. The finished product is paper. Different pulping methods produce different atmospheric pollution. The sulfate pulping method and alkali recovery furnace are prone to produce waste gas with a foul odor, commonly known as odor. The main components of the odor are hydrogen sulfide, methane, methyl mercaptan, methyl sulfide, dimethyl sulfide, dimethyl disulfide and other flammable, explosive and toxic and harmful gases.
[0003] At present, the common means of eliminating odor is to recycle and burn the odor, or to use photocatalytic odor treatment equipment, activated carbon adsorption devices, etc. for separate purification. Spray towers can also be used to neutralize part of the odor to reduce the odor concentration.
[0004] When burning odor, pipes are usually used to transport the odor to an incinerator. However, due to the complex composition of odor and its flammable and explosive properties, during the odor recovery and transportation process, excessive gas transportation pressure and static electricity accumulation can easily cause explosions. Existing odor treatment systems often ignore explosion-proof measures during the odor recovery process, or the explosion-proof cost is too high, the structure is complex, and the reliability is low, posing a threat to the safety of people's lives and property and the safety of equipment.

Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0025] Reference Figure 1 This embodiment proposes a odor recovery explosion-proof system structure, including a recovery pipeline 1, an odor scrubber 2 is connected to the air inlet end of the recovery pipeline 1, the other end of the recovery pipeline 1 is connected to the incinerator 3, a blower 4 is arranged in the middle of the recovery pipeline 1, a first explosion-proof plate 5 is installed on the air duct of the blower 4, and a plurality of static elimination devices 6 are connected to the recovery pipeline 1. The plurality of static elimination devices 6 are arranged along the length direction of the recovery pipeline 1, and the adjacent static elimination devices 6 are separated by 25-30 meters, such as 25 meters, 26 meters, 27 meters, 28 meters, 29 meters or 30 meters. The specific distance depends on actual needs. A blower 7 is connected between the blower 4 and the incinerator 3, and the blower 7 is also connected to one end of the explosion-proof pipeline 9. The explosion-proof pipeline 9 extends from the blower 7 to the direction away from the incinerator 3, and a second explosion-proof plate 8 is arranged at the other end of the explosion-proof pipeline 9. The blower 4 and the blower 7 are both electrically connected to the power frequency detector and the controller, and the power frequency detector is electrically connected to the controller. Cameras are installed at the air inlet of the recovery pipeline 1, the air supply fan 4, the blower 7 and one or more of the incinerator 3. Gas detection alarms and diffusers are installed at the pipeline nodes of the recovery pipeline 1, the air supply fan 4, the blower 7 and one or more of the incinerator 3, and the gas detection alarm is electrically connected to the diffuser.
[0026] The working principle of this embodiment is:
[0027] When the temperature and pressure at the air blower 4 exceed the specified temperature and pressure of the first explosion-proof disc 5 and the second explosion-proof disc, the first explosion-proof disc 5 and the second explosion-proof disc can explode first to release the pressure, avoid the occurrence of explosion or reduce the damage of the explosion, and protect the safety of the air blower 4 and the blower 7. The position of the second explosion-proof disc 8 is the explosion-proof port of the blower 7. The explosion-proof port of the blower 7 is set in a safe area away from the incinerator 3, which can ensure the safety of explosion relief and protect the incinerator 3.

The controller can control the operation of the air blower 4 and the blower 7 through the detection data of the power frequency detector to prevent the actual air volume of the air blower 4 and the blower 7 from exceeding the rated air volume, thereby ensuring the safety of odor recovery and reducing the possibility of explosion. The camera can monitor important equipment, such as the air inlet of the recovery pipe 1, the air blower 4, the blower 7 and the incinerator 3 in real time to ensure the safety of odor recovery, reduce the possibility of explosion, and protect the safety of equipment. The gas detection alarm can detect the change of odor concentration in real time to ensure the safety of odor recovery and reduce the possibility of explosion. When the gas detection alarm detects that the odor concentration exceeds the standard, the fan can be started to force ventilation to prevent the danger of odor accumulation. The above measures can effectively improve the safety of odor recovery and reduce the possibility of explosion. The structure is simple, the operation is reliable, the cost is low, and it can protect important equipment and reduce losses in the event of an accident.
