Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly relates to a waste gas dust removal treatment device for a pressure spray drying tower. Background Art

[0002] In modern industrial production, pressure spray drying towers are widely used in multiple fields such as food, medicine, and chemical industry. The pressure spray drying tower atomizes liquid materials into fine droplets, exchanges heat with hot air, and rapidly evaporates the water in the droplets, thereby achieving the drying of the materials. However, during the drying process, the pressure spray drying tower generates a large amount of waste gas.

[0003] These waste gases usually contain pollutants such as dust and particulate matter. If not effectively treated and directly discharged into the atmosphere, these waste gases will cause serious pollution to the environment. On the one hand, pollutants such as dust will reduce air quality and affect people's health and quality of life. Dust particles in the air may cause respiratory diseases and damage the human respiratory system. At the same time, a large amount of waste gas emissions will also damage the ecological environment and affect the growth and survival of animals and plants. On the other hand, with the continuous improvement of environmental protection requirements, the state has formulated strict standards for the emission of industrial waste gas. Enterprises must take effective measures to treat the waste gas generated by the pressure spray drying tower to meet the requirements of environmental protection regulations.

[0024] The working principle of the present invention is as follows: The main body 1 of the spray drying tower discharges waste gas through the first gas transmission pipe 3. During the process of the waste gas passing through the first gas transmission pipe 3, it will come into contact with the dust-proof net 31, thereby filtering the dust contained in the waste gas. As time goes by, the dust will accumulate on the surface of the dust-proof net 31.

When the impact block 34 contacts the dust-proof net 31, it will cause the dust-proof net 31 to vibrate, so that the dust accumulated on the surface of the dust-proof net 31 will fall off, and the dust will be guided into the inside of the guide pipe 36 by the provided impact block 34, and then fall into the inside of the collection drawer 82 for subsequent processing. Subsequently, the solid and gas in the waste gas are further separated by the provided cyclone separator 4, and the solid will fall into the collection device below the cyclone separator 4. Among them, the waste gas enters the serpentine pipe 53 provided inside the water tank 5 through the second gas transmission pipe 9 provided. During this period, cold water can be injected into the inside of the water tank 5 through the water injection pipe 51. Subsequently, the heat contained in the waste gas in the serpentine pipe 53 is used to heat the cold water, thereby improving the utilization rate of the waste gas. When the waste gas passes through the serpentine pipe 53, it will enter the inside of the drying box 6 through the inside of the first connecting pipe 54 and the second connecting pipe 55. The placement drawer 62 can be pulled out through the cooperation of the provided first guide rail 63 and the first chute. Subsequently, the items to be dried are placed inside the placement drawer 62, and the heat in the waste gas is conducted to the placement drawer 62 through the provided heat conduction medium, thereby realizing the drying process of the items and further improving the utilization rate of the waste gas. After the waste gas passes through the drying box 6, it will enter the inside of the purification box 7 through the third connecting pipe 65. The staggered distribution of the partition plates 73 inside the purification box 7 can extend the residence time of the waste gas inside the purification box 7, so that the waste gas is purified and filtered by filling activated carbon in the gaps between the partition plates 73, and then discharged through the exhaust pipe 74, thereby avoiding directly discharging the waste gas to affect the environment while improving the utilization rate of the waste gas.
