Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to a high-efficiency purification device based on a molecular sieve rotor + RTO. Background Art

[0002] Waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment and air sterilization and purification. Generally speaking, waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before external discharge to meet the national waste gas discharge standards. At present, molecular sieve adsorption towers (mainly including molecular sieve rotors) are often used in conjunction with RTO control methods to absorb harmful components in waste gas.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: during the execution of the current molecular sieve adsorption tower in conjunction with the RTO control method, the exhaust gas is usually passed into the molecular sieve adsorption tower and then directly discharged after being treated by the molecular sieve rotor. The contact and reaction time between the exhaust gas and the molecular sieve rotor is relatively short, resulting in incomplete absorption of harmful components.

[0004] To this end, we proposed a high-efficiency purification device based on molecular sieve rotor + RTO to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a high-efficiency purification device based on a molecular sieve rotor + RTO, so that the exhaust gas can be treated with harmful components by the molecular sieve rotor multiple times, thereby making the purification and absorption of the exhaust gas more effective and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A molecular sieve rotor + RTO high-efficiency purification device, comprising a base and a purification tank integrally welded to the base, an input pipe and an output pipe are fixedly connected to opposite side walls of the purification tank, two side supports are symmetrically welded to the outside of the purification tank, and motors are horizontally mounted on the two side supports, wherein the output shafts of the two motors are coaxially connected to the outer shafts, and the two outer shafts are fixedly sleeved with outer pulleys;

[0008] Inner supports are welded on both sides of the bottom wall of the inner cavity of the purification tank, and rotating shafts are rotatably connected to the two inner supports, and inner pulleys are coaxially connected to the opposite sides of the two rotating shafts, that is, there are two inner pulleys in total, and the outer pulleys correspond to the inner pulleys one by one, that is, one outer pulley corresponds to one inner pulley, and the corresponding outer pulleys and inner pulleys are connected by belts;

[0009] Molecular sieve rotors are coaxially connected to the opposite sides of the two rotating shafts, and a guide block is integrally filled on the side of the purification tank close to the output pipe. The guide block and the purification tank are integrated, and a forward flow channel connected to the output pipe is formed at the center of the guide block, and two reverse flow channels that penetrate the purification tank and lead into the inner cavity of the purification tank are formed in the forward flow channel.

[0010] As a preferred implementation scheme, the two side supports are both U-shaped in design, and the two outer shafts are respectively located in the inner cavities of the two side supports and are rotatably connected to the side supports; so that the two outer shafts can operate stably under the drive of two motors, and the motors need to be powered by external power facilities.

[0011] As a preferred embodiment, through holes are formed on both sides of the outer side of the purification tank, and the two belts pass through the two through holes respectively, so that the belts can run smoothly.

[0012] As a preferred embodiment, the two through holes are respectively located on the inner sides of the two side supports; so that the two side supports can block the openings of the two through holes, thereby preventing the exhaust gas from entering the through holes from the purification tank and overflowing to the outside.

[0013] As a preferred implementation scheme, the inner pulley, rotating shaft and molecular sieve rotor on the inner support are all coaxially designed, and the two molecular sieve rotors are placed vertically, and the two molecular sieve rotors are distributed on both sides of the inner cavity of the purification tank; thereby facilitating the use of two molecular sieve rotors to absorb the exhaust gas twice in a short period of time, thereby achieving a better effect in absorbing harmful components in the exhaust gas.

[0014] As a preferred embodiment, a valve is installed on the output pipe; the valve is a common valve body in the prior art, such as an electric valve.

[0015] As a preferred embodiment, the two reverse flow channels are symmetrically distributed on the upper and lower sides of the purification tank; when the valve closes the output pipe, the two reverse flow channels work together to send the absorbed and treated waste gas to the front of the two molecular sieve wheels for re-absorption.

[0016] In summary, the technical effects and advantages of the utility model are as follows:

[0017] The molecular sieve rotor + RTO high-efficiency purification device makes the waste gas circulate in the purification tank for many times during the process of the molecular sieve rotor rotating and absorbing harmful components in the waste gas, so that the waste gas can be absorbed by the molecular sieve rotor for many times, thereby making the purification and absorption of the waste gas more effective.

[0018] The high-efficiency purification device based on molecular sieve rotor + RTO has two molecular sieve rotors that can cooperate with each other in the purification tank, so that the exhaust gas is immediately absorbed by the second molecular sieve rotor after being absorbed by the first molecular sieve rotor, which is convenient for more detailed absorption of harmful components in a short time, so that the removal effect of harmful components is better.

[0026] Inner supports 10 are welded on both sides of the bottom wall of the inner cavity of the purification tank 2, and rotating shafts 11 are rotatably connected to the two inner supports 10, and inner pulleys 9 are coaxially connected to the sides of the two rotating shafts 11 facing each other, that is, there are two inner pulleys 9, and the outer pulleys 7 correspond to the inner pulleys 9 one by one, that is, one outer pulley 7 corresponds to one inner pulley 9, and the corresponding outer pulleys 7 and inner pulleys 9 are connected by belts 8. Through holes 18 are formed on both sides of the outer side of the purification tank 2, and the two belts 8 pass through the two through holes 18 respectively, so that the belts 8 can run smoothly. The two through holes 18 are respectively located on the inner sides of the two side supports 4, so that the two side supports 4 can block the openings of the two through holes 18, thereby preventing the exhaust gas from entering the through holes 18 from the purification tank 2 and overflowing to the outside;

[0027] Molecular sieve rotors 12 are coaxially connected to the opposite sides of the two rotating shafts 11, and the inner pulley 9, the rotating shaft 11 and the molecular sieve rotor 12 on the inner support 10 are all coaxially designed, and the two molecular sieve rotors 12 are vertically placed. The two molecular sieve rotors 12 are distributed on both sides of the inner cavity of the purification tank 2, so that the two molecular sieve rotors 12 can be used to absorb the exhaust gas twice in a short time, so that the effect of absorbing harmful components in the exhaust gas is better;

[0028] A guide block 13 is integrally filled on one side of the inner cavity of the purification tank 2 near the output pipe 15, and the guide block 13 is integrated with the purification tank 2.
