Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a device for adsorbing and treating waste gas from morel mushroom production residue. Background Technology

[0002] The production of morel mushrooms generates waste gas containing organic matter. If this waste gas is directly released into the atmosphere, it will not only pollute the environment but may also harm human health. Therefore, developing a highly efficient and stable waste gas adsorption and treatment device is of paramount importance.

[0003] Traditional waste gas treatment methods often suffer from low treatment efficiency, unstable operation, and high equipment maintenance costs. In particular, traditional methods struggle to achieve ideal treatment results for waste gases containing complex organic matter, such as those from morel mushroom production residue.

[0004] In recent years, activated carbon fiber adsorption technology has been widely used in the field of waste gas treatment due to its high adsorption capacity, rapid adsorption rate, and good regeneration performance. However, existing activated carbon fiber adsorption devices still have problems when treating waste gas from morel mushroom production residues, such as untimely treatment after adsorption saturation, high energy consumption during regeneration, and poor continuous operation capability of the system. Utility Model Content

[0005] To address some of the problems existing in the prior art, this utility model provides an adsorption treatment device for waste gas from morel mushroom production residue. An automatic control system enables alternating adsorption and regeneration of the adsorbers, ensuring that at least one adsorber is always operational, thus achieving continuous waste gas treatment. Simultaneously, a steam assembly is used to desorb and regenerate the saturated activated carbon fibers, and the desorbed organic matter is sent to a recovery system, improving treatment efficiency and achieving resource recycling.

[0006] To achieve the above objectives, this utility model provides an adsorption treatment device for waste gas from morel mushroom production residue, comprising an adsorption device body, wherein the adsorption device body includes at least two activated carbon fiber adsorbers, the interior of which is filled with activated carbon fiber blocks, and the activated carbon fiber adsorbers are equipped with an automatic control system and controlled by the automatic control system to achieve alternating adsorption. A steam assembly is externally connected to the activated carbon fiber adsorbers, and the steam assembly desorbs the organic matter adsorbed on the activated carbon fibers through steam pressure and sends it to the recovery system.

[0007] As a further improvement of this utility model, in order to enhance the driving force of the waste gas entering the activated carbon fiber adsorber and ensure the effective adsorption of the waste gas, the activated carbon fiber adsorber is equipped with an adsorption fan, and a gas buffer tank is connected to one end of the adsorption fan.

[0008] As a further improvement of this utility model, in order to help the uniform discharge of steam and realize the condensation and recovery of organic matter in the steam, thereby further improving the resource recovery rate, steam discharge pipes are respectively provided on both sides of the activated carbon fiber adsorber. The steam discharge pipes are arranged in a U-shape, and a tube condenser is connected to one side of the steam discharge pipes.

[0009] As a further improvement of this utility model, in order to ensure the safe discharge of the treated waste gas and further improve the condensation efficiency to ensure the full recovery of organic matter, a purified discharge pipe is provided below the activated carbon fiber adsorber, and a spiral plate condenser is connected below the tube condenser.

[0010] As a further improvement of this utility model, in order to prevent dust and ignition sources in the exhaust gas from entering the adsorber and to ensure the safe operation of the device, a dust removal and flame arrester is connected to the bottom of the gas buffer tank. The dust removal and flame arrester is connected to a direct discharge pipe. The direct discharge pipe is connected to the activated carbon fiber adsorber. A drying dust collector is also provided in conjunction with the direct discharge pipe.

[0011] As a further improvement of this utility model, in order to ensure the stability of the steam pressure inside the steam inlet pipe, the steam assembly includes a steam inlet pipe disposed on the activated carbon fiber adsorber, and the steam inlet pipe is equipped with a self-regulating pressure reducing valve.

[0012] As a further improvement of this utility model, in order to accelerate the drying process of the activated carbon fiber adsorber and improve the regeneration efficiency, the activated carbon fiber adsorber is equipped with a drying fan, a drying duct is provided between the drying fan and the activated carbon fiber adsorber, and a pneumatic butterfly valve is provided in the drying duct.

[0013] As a further improvement of this utility model, in order to achieve effective separation and storage of condensate and facilitate subsequent processing and resource recycling, the spiral plate condenser is connected to a separation tank, and the separation tank is equipped with an intermediate storage tank, which is equipped with a solvent pump.

[0014] In operation, the core of this morel mushroom production residue waste gas adsorption treatment device lies in utilizing at least two activated carbon fiber adsorbers, which alternately adsorb and regenerate under the control of an automatic control system. First, the waste gas enters the dust collector and flame arrester through a direct discharge pipe to remove dust and potential ignition sources, and then enters the gas buffer tank to stabilize the airflow.

[0015] Next, the exhaust gas is evenly fed into the activated carbon fiber adsorber by the adsorption fan. Under the action of the activated carbon fiber blocks, the organic matter in the exhaust gas is efficiently adsorbed. When one adsorber reaches saturation, the automatic control system switches to another adsorber to continue adsorption, while simultaneously regenerating the saturated adsorber.

[0016] During regeneration, a stable pressure of steam is introduced into the adsorber through a steam inlet pipe, using the steam pressure to desorb the organic matter adsorbed on the activated carbon fibers. The resulting mixture of steam and organic matter is discharged through a U-shaped steam outlet pipe and enters a tube-and-shell condenser for initial condensation. The mixture then enters a spiral plate condenser for further condensation. The condensed liquid flows into a separation tank for separation, and the separated organic matter is sent to an intermediate storage tank and then further processed or recovered via a solvent pump.

[0017] Meanwhile, a drying fan blows dry air into the regenerated adsorber through a drying duct, accelerating the drying process and preparing it for the next adsorption cycle. The drying fan is connected to a drying dust collector to further treat the dust generated during the drying process, preventing it from re-entering the adsorber and affecting its adsorption efficiency. Under the precise control of the automatic control system, the entire workflow achieves efficient waste gas treatment and resource recovery.

[0018] The beneficial effects of this utility model are as follows:

[0019] Highly efficient continuous treatment: By setting up at least two activated carbon fiber adsorbers and achieving alternating adsorption and regeneration under the control of an automatic control system, the continuity of waste gas treatment is ensured, greatly improving treatment efficiency.

[0020] Resource recycling: Steam components are used to desorb and regenerate saturated activated carbon fibers, and the desorbed organic matter is sent to the recycling system, which realizes the effective recycling and reuse of resources, reduces production costs, and reduces environmental pollution.

[0021] Safe and stable operation: The device is equipped with safety facilities such as dust removal flame arresters and gas buffer tanks, which effectively prevent dust and ignition sources in the exhaust gas from entering the adsorber, ensuring the safe and stable operation of the device.

[0022] High-efficiency condensation and recovery: By using tube condensers and spiral plate condensers in combination, high-efficiency condensation and recovery of organic matter in steam is achieved, improving the resource recovery rate and reducing the amount of waste gas emissions.

[0023] Intelligent and precise control: The automatic control system and self-regulating pressure reducing valve ensure the stability and accuracy of the equipment operation, reduce the failure rate, and improve production efficiency and product quality.

[0024] Optimized drying effect: The combined use of the drying fan and pneumatic butterfly valve enables precise control of the adsorber drying process, accelerates the drying speed, improves regeneration efficiency, and fully prepares the adsorption for the next adsorption cycle.
