Description

Technical Field

[0001] This invention relates to the field of waste gas pollution treatment technology, and more specifically, to a fully automatic online adsorption and desorption integrated device for organic waste gas. Background Technology

[0002] The fully automatic online adsorption and desorption integrated device for organic waste gas is an integrated environmental protection equipment. Its core function is to achieve efficient treatment and resource utilization of industrial organic waste gas (VOCs) through a closed-loop synergistic mechanism of adsorption and desorption.

[0003] In the current field of VOCs organic waste gas treatment, the mainstream adsorption and desorption treatment devices mainly include fixed-bed activated carbon adsorption devices, block zeolite rotary adsorption devices, and honeycomb activated carbon adsorption devices. Their core technical solution is to adsorb VOCs in waste gas through fixed-state adsorption materials. After adsorption saturation, the adsorption material is regenerated and VOCs are decomposed by heating desorption combined with catalytic combustion. In existing fixed-bed and rotary devices, the usable adsorption area of ​​honeycomb activated carbon is only the side facing the waste gas, while the side facing away from the waste gas is not fully utilized, which affects the treatment efficiency of the adsorption plate for waste gas. Moreover, after the activated carbon adsorption plate is blocked, the treatment quality of waste gas cannot be guaranteed, and the adsorption plate needs to be replaced frequently after blockage, which further affects the treatment efficiency of the adsorption plate for waste gas.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1) When this fully automatic online adsorption and desorption integrated device for organic waste gas is in use, the main fan operates to discharge the gas inside multiple filter cartridges through the common pipe and the purified gas discharge pipe. The filter cartridges are under negative pressure. At this time, the powdered molecular sieves around the filter cartridges adsorb onto the filter cartridge surfaces, forming a powder layer. As the lifting ring and inner ring move upwards on the filter cartridge surface, the powdered molecular sieves inside the fusion chamber are simultaneously blown out from multiple through holes under the action of high-pressure gas, evenly adhering to the surface of the filter cartridges, ensuring the filter cartridge surface... A uniform powdery molecular layer is formed on the surface. High-pressure gas blown out by the blower is blown into the fluidized bed of powdery molecular sieve through the powder outlet. The high-pressure gas blows the powdery molecular sieve that has sunk inside the fixed cylinder upward again, ensuring that the powdery molecular sieve around the multiple cloth filter is adsorbed onto the surface of the multiple cloth filter to form a powder layer. Compared with the traditional fixed bed activated carbon adsorption device, this adsorption and desorption integrated device forms a powder layer on the surface of multiple cloth filter to adsorb and treat the waste gas, which increases the adsorption area of ​​the powder layer on the waste gas, thereby improving the treatment efficiency of the powdery molecular sieve layer on the waste gas.

[0018] 2) When this fully automatic online adsorption and desorption integrated device for organic waste gas is in use, after the powder layer is saturated with adsorbed impurities, the main fan rotates to fill multiple cloth filter cartridges with air. At this time, the powder layer on the surface of the multiple cloth filter cartridges is blown off to form powdered molecular sieves. The saturated powdered molecular sieves enter the desorption chamber through connecting pipe three. The desorbed molecular sieves enter the mixing chamber through the powder collection port and powder inlet pipe two. Powdered molecular sieves are then fed into the fluidized bed of powdered molecular sieves again. Compared with traditional activated carbon adsorption plates, the powder layer formed by this powdered molecular sieve can ensure the treatment quality of waste gas, and there is no need to replace the adsorption plates. Only the saturated powdered molecular sieves need to be desorbed to complete the reuse of the molecular sieves. Attached Figure Description

Multiple through holes 7, connected to the eutectic cavity 8, are provided on the inner wall of the inner ring 4.

During the upward movement of the lifting ring 3 and inner ring 4 on the surface of the cloth filter cartridges 2, the powder inside the fusion chamber 8... Under the action of high-pressure gas, molecular sieves are simultaneously blown out from multiple through holes 7, uniformly adhering to the surface of the cloth filter 2, ensuring that a uniform powdery molecular layer is formed on the surface of the cloth filter 2. The high-pressure gas blown out by the blower 44 is blown into the interior of the powdery molecular sieve fluidized bed 1 through the powder outlet 41. The high-pressure gas blows the powdery molecular sieves that have sunk inside the fixed cylinder 11 back up, ensuring that the powdery molecular sieves around the multiple cloth filters 2 are adsorbed onto the surface of the multiple cloth filters 2 to form a powder layer. Compared with the traditional fixed-bed activated carbon adsorption device, this adsorption and desorption integrated device forms a powder layer on the surface of multiple cloth filters 2 to adsorb and treat the waste gas, increasing the adsorption area of ​​the powder layer on the waste gas, thereby improving the treatment efficiency of the powdery molecular sieve layer on the waste gas.

The other interface of the three-way connector is connected to the powder outlet 41.

[0041] The operating steps of this invention are as follows: When using this fully automatic online adsorption and desorption integrated device for organic waste gas, firstly, the powdered molecular sieve is placed into the mixing chamber 27 for uniform mixing. Then, the solenoid valve 29 is opened, and simultaneously the powder inlet fan 31 and the main fan 26 are started. At this time, the powder inlet fan 31 operates, injecting high-pressure gas into the connecting pipe 30. The high-pressure gas inside the connecting pipe 30 enters the mixing chamber 27, and then carries the powdered molecular sieve through the powder inlet pipe 28 into the main powder inlet pipe 16. The powdered molecular sieve inside the main powder inlet pipe 16 is divided into two paths: one path enters the powdered molecular sieve fluidized bed 1 through the fixed cylinder 11, surrounding the multiple cloth filter cartridges 2; the other path enters the eutectic chamber 8 through the guide pipe 17 and a three-way pipe. The main fan 26... The forward rotation discharges the gas inside the multiple cartridge filters 2 through the common pipe 18 and the purified gas discharge pipe 25. The multiple cartridge filters 2 are under negative pressure. At this time, the powdered molecular sieves around the multiple cartridge filters 2 are adsorbed onto the surface of the multiple cartridge filters 2, forming a powder layer. Then, the powdered molecular sieves gradually sink along the baffle plate 14. To achieve uniform adsorption of powdered molecular sieves on the surface of the multiple cartridge filters 2, when the main fan 26 is working, the motor 24 rotates. The rotation of the motor 24 drives the threaded rod 22 to rotate, causing the lifting frame 23 to move upward, which in turn moves the multiple lifting rings 3 upward. The movement of the lifting rings 3 causes the inner ring 4 to move upward. During the upward movement of the lifting rings 3 and the inner ring 4 on the surface of the cartridge filters 2, the powdered molecular sieves inside the fusion chamber 8... Under the action of high-pressure gas, it is blown out simultaneously from multiple through holes 7. The powdered molecular sieve blown out from multiple through holes 7 adheres evenly to the surface of the cloth filter 2 as the lifting ring 3 moves upward, ensuring that a uniform powdered molecular layer is formed on the surface of the cloth filter 2. When the powdered molecular sieve around multiple cloth filters 2 is adsorbed, the blower 44 is started to rotate forward (at this time, the solenoid valve 43 is in the closed state). The high-pressure gas blown out by the blower 44 is blown into the interior of the powdered molecular sieve fluidized bed 1 through the powder outlet 41. Then, the high-pressure gas moves upward along the arc-shaped cone 12 and its bottom cavity. Since the inner wall of the powdered molecular sieve fluidized bed 1 is fixedly installed with a fixing ring 10, the gas moving upward in the bottom cavity enters the fixed cylinder 11 and removes the sinking powdered molecules. The air is blown upwards again, ensuring that the powdered molecular sieves around the multiple filter cartridges 2 are adsorbed onto the surface of the multiple filter cartridges 2 to form a powder layer. The high-pressure gas moves upwards along the arc-shaped cone 12, and then enters the interior of the fixed cylinder 11 through several ventilation holes 13 on the surface of the fixed cylinder 11. Then, the powdered molecular sieves around the multiple filter cartridges 2 are further lifted upwards, ensuring that the powdered molecular sieves around the multiple filter cartridges 2 are adsorbed onto the surface of the multiple filter cartridges 2 to form a powder layer. After the powdered molecular sieves have been adsorbed, the blower 44 and the powder inlet fan 31 are stopped. At this time, the solenoid valve 29 is closed, and waste gas is introduced into the fluidized bed 1 of powdered molecular sieves. The waste gas reaches the area around the multiple filter cartridges 2 through the fixed cylinder 11, and negative pressure is generated by the positive rotation of the main fan 26.At this time, the exhaust gas is filtered through the powder layer on the surface of multiple cloth filter cartridges 2. The filtered gas is discharged through the common pipe 18 and the purified gas discharge pipe 25. The powder layer adsorbs the impurities inside the exhaust gas. When the powder layer is saturated with impurities, the intake of exhaust gas is stopped. At this time, the solenoid valve 43 opens, the blower 44 and the main blower 26 reverse, and the main blower 26 rotates to fill the multiple cloth filter cartridges 2 with air. At this time, the powder layer on the surface of the multiple cloth filter cartridges 2 is blown off to form powdered molecular sieves. The blower 44 reverses and blows the powdered molecular sieves out from the powder outlet 41. Then, the saturated powdered molecular sieves enter the desorption box 32 through the connecting pipe 42. At this time, the solenoid valve 43 closes and the blower 44 stops working. The desorption box 32 has a built-in heating system to heat the saturated powdered molecular sieves. Molecular sieves undergo heating and desorption, and the desorbed waste powder is discharged. At this time, the return powder fan 36 and solenoid valve 35 are turned on. The desorbed molecular sieve enters the mixing box 27 through the powder collection port 33 and the powder inlet pipe 34. Then, following the steps of introducing powdered molecular sieve into the fluidized bed 1, powdered molecular sieve is introduced into the fluidized bed 1 again. The exhaust gas after heating and desorption enters the catalytic combustion bed 37 through the connecting pipe 38 (at this time, solenoid valve 39 is opened). The exhaust gas is then heated and catalyzed by the catalytic combustion bed 37, and the clean gas is discharged through the exhaust pipe 40. In this scheme, the main fan 26 operates to discharge the gas inside the multiple filter cartridges 2 through the common pipe 18 and the purified gas discharge pipe 25. The multiple filter cartridges 2 are under negative pressure. In this state, the powdered molecular sieves around the multiple cartridge filters 2 are adsorbed onto the surface of the multiple cartridge filters 2 to form a powder layer. As the lifting ring 3 and inner ring 4 move upward on the surface of the cartridge filters 2, the powdered molecular sieves inside the fusion chamber 8 are simultaneously blown out from multiple through holes 7 under the action of high-pressure gas, uniformly adhering to the surface of the cartridge filters 2, ensuring that a uniform powdered molecular layer is formed on the surface of the cartridge filters 2. The high-pressure gas blown out by the blower 44 is blown into the powdered molecular sieve fluidized bed 1 through the powder outlet 41. The high-pressure gas blows the powdered molecular sieves that have sunk inside the fixed cylinder 11 upward again, ensuring that the powdered molecular sieves around the multiple cartridge filters 2 are adsorbed onto the surface of the multiple cartridge filters 2 to form a powder layer. Compared with the traditional fixed-bed activated carbon adsorption device, this adsorption... In the integrated desorption and purification system, a powder layer forms on the surface of multiple cartridge filters 2 to adsorb waste gas, increasing the adsorption area of ​​the powder layer and thus improving the treatment efficiency of the powdered molecular sieve layer. When the powder layer is saturated with impurities, the main fan 26 rotates to fill the multiple cartridge filters 2 with air. At this time, the powder layer on the surface of the multiple cartridge filters 2 is blown off to form powdered molecular sieves. The saturated powdered molecular sieves enter the desorption box 32 through the connecting pipe 3 42. The desorbed molecular sieves enter the mixing box 27 through the powder collection port 33 and the powder inlet pipe 2 34, and are then fed back into the powdered molecular sieve fluidized bed 1. Compared with traditional activated carbon adsorption plates, the powder layer formed by this powdered molecular sieve can ensure the treatment quality of waste gas and eliminates the need to replace the adsorption plates.The molecular sieve can be reused simply by desorbing the saturated powdered sieve.
