Description

Technical Field

[0001] The utility model relates to the technical field of adsorption and desorption equipment, in particular to an adsorption and desorption system of a macroporous resin. Background Art

[0002] At present, adsorption and desorption use macroporous resin as adsorbent. In the production process, it is mainly aimed at acidic gases in waste gas with low water solubility, poor biodegradability, strong corrosiveness, and secondary pollution easily generated during oxidation and incineration. After the existing macroporous resin adsorption is completed, due to the different rates of adsorption and desorption, the working time of the adsorption tower and the desorption tower is also different, which is not convenient for complete desorption of the adsorbate in the desorption tower. The utilization rate of the adsorbent is low, and it is easy to re-enter the adsorption process before desorption is completed, resulting in incomplete desorption of the desorption tower. If the two towers desorb at the same time, it will cause production shutdown, resulting in serious economic losses. Utility Model Content

[0003] In order to facilitate the complete desorption of the desorption container and improve the utilization rate of the adsorbent, the utility model provides a macroporous resin adsorption and desorption system (this should be the same as the name of the utility model and no other words should be added).

[0004] The macroporous resin adsorption and desorption system provided by the utility model adopts the following technical scheme:

[0005] The adsorption and desorption system of macroporous resin comprises a raw material input module, a series adsorption module, a steam desorption module, a separation module, an electrical control module, a plurality of pipelines and a plurality of solenoid valves, wherein the series adsorption module, the steam desorption module, the separation module and the plurality of solenoid valves are all communicatively connected with the electrical control module, the series adsorption module comprises adsorber 1, adsorber 2 and adsorber 3 which are sequentially connected in series through corresponding pipelines, the adsorber 1, adsorber 2 and adsorber 3, the separation module comprises a condensation module and an oil-water separator; the electrical control module comprises a control system, a security system and an alarm system, and the security system and the alarm system are both communicatively connected with the control system.

[0017] As the technical solution of the utility model, the hardware setting provided is only to facilitate the complete desorption of the desorption container on the basis of the hardware facilities and improve the utilization rate of the adsorbent. The specific method of how to achieve the complete desorption of the desorption container and improve the utilization rate of the adsorbent is not the technical problem to be solved and the object of protection of the utility model. At the same time, the communication method between the devices adopts the existing communication method, which is not the innovation point of this application.

[0018] In summary, the utility model has the following beneficial technical effects:

[0019] 1. This control is equipped with an adsorption and desorption system with two adsorbers and one desorber.

[0020] 2. This system is equipped with two-stage adsorption. At the beginning of adsorption, the waste gas first enters adsorber 1 for adsorption, then enters the adsorption hot intermediate spray condenser for cooling, and then the waste gas enters adsorber 2 for secondary adsorption. The waste gas from adsorber 2 or adsorber 3 enters the condensation module, and the waste gas can enter the primary condenser and finally enter the oil-water separator. The waste gas that does not condense after the primary condenser enters the secondary condenser again. After condensation again, the waste gas that still does not condense enters the gas-liquid separator through the static compressor and returns to adsorber 1 or adsorber 2 for adsorption again. The cycle is repeated. The multiple adsorption of waste gas is conducive to improving the utilization rate of macroporous resin adsorbent, increasing the adsorption upper limit of the entire adsorption and desorption system, and reducing the emission of acidic waste gas.

[0021] 3. This system is equipped with an alarm system. The air outlets of adsorber 1, adsorber 2, and adsorber 3 are all fixedly connected with VOCs concentration detection sensors. When the system detects that the VOCs concentration exceeds the lower explosion limit of the mixed gas, the system automatically alarms, automatically interlocks and cuts off the air inlet valve in the pipeline within 5 to 8 seconds, opens the emergency discharge valve and bypass valve of the pipeline, and the exhaust gas is introduced into the emergency bypass pipeline for discharge; at the same time, if any one of adsorber 1, adsorber 2, and adsorber 3 exceeds the temperature (120℃) or the pressure (65000Pa), an alarm will be issued. The double protection ensures the safe operation of the system, opens the emergency discharge valve, opens the bypass valve of the pipeline, and introduces the exhaust gas into the emergency pipeline for discharge.

[0038] The implementation principle of the macroporous resin adsorption and desorption system of the utility model embodiment is:

[0039] 1. At the beginning of adsorption, the waste gas first enters adsorber 1 for adsorption, then enters adsorption heat intermediate spray condenser 14 for cooling (the waste gas temperature rises due to adsorption heat release), and then the waste gas enters adsorber 2 2 for secondary adsorption; when the VOCs concentration in the waste gas at the outlet of adsorber 2 reaches a certain value, the adsorption of adsorber 1 is stopped, and adsorber 2 2 and adsorber 3 3 are switched to adsorption, and adsorber 1 enters the desorption process, that is, adsorber 1 is desorbed, and adsorber 2 2 and adsorber 3 3 continue to adsorb; when the VOCs concentration in the waste gas at the outlet of adsorber 3 3 reaches a certain value, the adsorption of adsorber 3 3 is stopped, and adsorber 1 1 and adsorber 2 2 are switched back to adsorption, and adsorber 3 3 enters the desorption process, and the cycle is repeated to maintain secondary adsorption;

[0040] 2. The adsorber switching time is based on the previous continuous sampling detection of the inlet concentration and the device outlet concentration. The higher inlet concentration and the non-penetration time are used to set the adsorption time and switching cycle;

[0041] 3. When adsorption starts, the waste gas first enters adsorber 1 for adsorption, then enters adsorption hot intermediate spray condenser 14 for cooling, and then the waste gas enters adsorber 2 2 for secondary adsorption. The waste gas from adsorber 2 2 or adsorber 3 3 enters the condensation module, and the waste gas can enter the primary condenser 5, and finally enter the oil-water separator 9. The waste gas that does not condense through the primary condenser 5 enters the secondary condenser 6 again. After condensation again, the waste gas that still does not condense enters the gas-liquid separator 4 through the static compressor, and returns to adsorber 1 or adsorber 2 2 for adsorption again. The cycle repeats, and the liquid in the gas-liquid separator 4, the liquid in the primary condenser 5 and the secondary condenser 6 all finally enter the oil-water separator 9. The oil phase material in the oil-water separator 9 is discharged into the oil storage tank, and the waste water is discharged into the wastewater station;

[0042] 4. After the desorption process (steam desorption, water cooling, air + nitrogen drainage and conditioning) has been carried out for a period of time, the organic matter adsorbed in the macroporous resin is basically completely resolved, and then it is cooled to the set temperature by water, and after air + nitrogen drainage and conditioning, adsorber 1 or adsorber 2 or adsorber 3 is regenerated and ready for use.
