Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a cyclone spray tower for waste gas treatment. Background Art

[0002] Atmospheric environmental governance is an important means of maintaining sustainable development. Regardless of whether it is waste gas emissions from factory buildings or waste gas generated by industrial working environments, the waste gas cannot be directly discharged into the air after it is generated. It is necessary to purify the waste gas under the premise of meeting the standards for gas emissions and governance. For example, a cyclone spray tower for waste gas treatment can spray liquid on the waste gas during its generation and flow process to remove impurities and harmful substances in the waste gas, so that the discharged atmosphere will not cause pollution and burden on the environment.

[0003] Existing cyclone spray towers for waste gas treatment generally use cyclone gas to increase the retention time of waste gas in the spray tower. Under the continuous waste gas transportation operation, the reaction solution continuously sprayed in the spray tower is used to mix and chemically react with the molecules of substances in the waste gas to achieve the effect of waste gas treatment. Although this operation process can achieve the treatment and processing of waste gas, there are also some problems in its use, such as:

[0004] In order to achieve rapid treatment of harmful substances and dust in exhaust gas, the generated cyclone is continuously sprayed by spraying water mist. Although it can achieve the effect of simultaneous treatment of harmful substances and dust, the dust condenses into clumps under the action of water mist and will be mixed into the treatment liquid to be recycled in large quantities, affecting the recovery and treatment of the treatment liquid. At the same time, the dust clumps will accelerate the absorption of water mist, affecting the stability of the spraying water mist in the treatment of harmful substance molecules in the air, resulting in poor exhaust gas treatment efficiency and low quality of treated exhaust gas.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original cyclone spray tower for waste gas treatment. Summary of the invention

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example 1: Please refer to Figure 1-Figure 12 The present invention provides a technical solution: a cyclone spray tower for waste gas treatment, comprising:

[0047] A cyclone separation tank 1 is provided with a spray tank 2, and a water tower pipe 3 is provided on the sides of the cyclone separation tank 1 and the spray tank 2, and an air guide pipe 4 is provided through the water tower pipe 3; the heated waste gas treatment liquid is stored inside the water tower pipe 3, wherein the air guide pipe 4 inside the water tower pipe 3 is spirally separated, and a water pump is provided at the bottom of the water tower pipe 3 and the connection point of the circulating water pipe 5; an air pump is provided at the connection point of the air guide pipe 4 and the cyclone separation tank 1;

[0048] In the above technical solution, if Figure 3 and Figure 4 As shown, the water tower pipe 3 is used to continuously replenish the heated treatment liquid storage through the external liquid pressurizing component. The water tower pipe 3 can be provided with a heat preservation structure so that the water tower pipe 3 can preheat the exhaust gas continuously flowing in the air guide pipe 4, thereby improving the activity of molecules and facilitating the acceleration of subsequent exhaust gas treatment efficiency. At the same time, the air pump and water pump can ensure the air pressure in the cyclone separation tank 1 and the hydraulic pressure inside the circulating water pipe 5.

[0049] This technical solution also includes Figure 5-Figure 9The technical solution shown is as follows: a circulating water pipe 5, the main pipeline is located inside the cyclone separation tank 1, wherein the lower end of the circulating water pipe 5 is connected to the inside of the water tower pipe 3, and a waste water pipe 6 is fixed on the outside of the circulating water pipe 5, and the waste water pipe 6 is located in the middle section of the cyclone separation tank 1. A secondary separation component is also arranged to realize the secondary separation of dust in the gas by airflow swirl; the secondary separation component includes a waste water pipe 6 arranged in the middle section, and the sections of the waste water pipe 6 are fixed with a secondary separation tank 601 and an airflow blocking ring 602 in sequence from bottom to top; wherein the secondary separation tank 601 is arranged in a funnel-shaped structure, and the top of the secondary separation tank 601 is located above the bottom of the airflow blocking ring 602; the middle part of the inner wall of the secondary separation tank 601 is arranged in an arc structure, the middle part of the outer wall of the airflow blocking ring 602 is arranged in an arc structure, and the two arc surfaces in the middle part of the inner wall of the secondary separation tank 601 and the middle part of the outer wall of the airflow blocking ring 602 are relatively distributed;

[0050] In this technical solution, the dust is separated from the gas by cyclone separation in the cyclone separation tank 1, and the airflow direction in the cyclone separation tank 1 is as follows: Figure 8 As shown, the airflow swirls to the bottom in the cyclone separation tank 1 and is transported upward from the middle position to the connection port of the cyclone separation tank 1 outlet and the spray tank 2 inlet.

An airflow discharge channel is reserved between the airflow through the water flow barrier cylinder 9 and the waste water pipe 6, and the spray treatment liquid exported from the spray pipe 7 is treated. The treated treatment liquid will only be introduced into the concave arc position of the water flow barrier cylinder 9 for storage due to the upward transport of gas at the position of the airflow discharge channel. The stored wastewater flows back to the waste water pipe 6 through the threaded conduit 10, thereby realizing the downward transportation of the wastewater in the waste water pipe 6.
