Detailed Description
The following describes the detailed implementation of the embodiments of the present utility model with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.
The utility model will be described in detail below with reference to the drawings in connection with exemplary embodiments.
Referring to fig. 1 and 2, a first exemplary embodiment of the present utility model provides a deodorizing system including a dust removing unit S2, a desulfurizing unit S3, a VOCs treating unit, a purifying line, and a waste discharging line.
Specifically, dust collector S2 is arranged in the dust in desorption foul smell, and desulfurization device S3 is arranged in the hydrogen sulfide in the desorption foul smell, and VOCs handles the assembly and is arranged in the VOCs in the desorption foul smell. Because the nasal-olfactory threshold of ammonia is about 378ug/m 3, and the concentration of ammonia in the odor in the garbage station is generally below 200ug/m 3, the ammonia in the garbage station has no odor-causing capability basically and can not be specially treated.
The VOCs treatment assembly specifically comprises a VOCs treatment unit S4, an adsorption fan S51, a desorption fan S52, a heating device S72, an end treatment device S8 and a heat exchange unit. The VOCs treatment unit S4 comprises a zeolite molecular sieve capable of removing VOCs in odor, and the zeolite molecular sieve has strong adsorption capacity for both water-soluble VOCs and non-water-soluble VOCs.
The flow of removing dust, hydrogen sulfide, water-soluble VOCs and water-insoluble VOCs in odor by the deodorizing system can refer to fig. 1, and during practical application, the purifying pipeline can be connected in series with the dust removing device S2, the desulfurizing device S3 and the VOCs processing unit S4 along the direction from the upstream end (i.e. the odor input end) to the downstream end (the purified gas output end) of the purifying pipeline, meanwhile, the purifying pipeline is also connected in series with the adsorption fan S51, and the adsorption fan S51 can be arranged between the VOCs processing unit S4 and the purified gas output end as shown in fig. 1, but can also be arranged at other positions, such as being close to the odor input end.
Under the drive of the adsorption fan S51, the odor entering the purifying pipeline from the odor input end can sequentially pass through the dust removing device S2, the desulfurizing device S3 and the VOCs treatment unit S4, so that dust, hydrogen sulfide, water-soluble VOCs and water-insoluble VOCs are sequentially removed, and the purified odor is discharged out of the purifying pipeline through the purified gas output end. The flow path of the odor in the purge line can be referred to as S11-S15 in fig. 1.
When the zeolite molecular sieve reaches an adsorption saturation state, the zeolite molecular sieve can not adsorb more VOCs, so that in order to ensure that the zeolite molecular sieve can be repeatedly used, the zeolite molecular sieve also needs to be subjected to desorption and regeneration at regular or irregular intervals. In the present exemplary embodiment, desorption and regeneration of the zeolite molecular sieve are achieved in combination with a waste discharge line.
Specifically, the exhaust line may be connected in series with the heating device S72, the VOCs processing unit S4, and the terminal processing device S8 in the direction from the upstream end (i.e., the desorption gas input end) to the downstream end (i.e., the desorption gas output end) thereof, and at the same time, the exhaust line may also be connected in series with the desorption fan S52, and the desorption fan S52 may be disposed between the VOCs processing unit S4 and the terminal processing device S8 as shown in fig. 2, but may also be disposed at other positions, such as being disposed close to the desorption gas input end.
Under the drive of the desorption fan S52, the desorption gas (such as clean air) entering the waste discharge pipeline from the desorption gas input end can sequentially pass through the heating device S72, the VOCs treatment unit S4 and the tail end treatment device S8, wherein the desorption gas can be heated to be high-temperature desorption gas after passing through the heating device S72, the high-temperature desorption gas can exchange heat with the zeolite molecular sieve when passing through the VOCs treatment unit S4, the adsorption capacity of the zeolite molecular sieve is reduced after the temperature of the zeolite molecular sieve rises, so that the VOCs are desorbed from the zeolite molecular sieve to further flow to the tail end treatment device S8 along with the desorption gas, the desorption gas entering the tail end treatment device S8 contains high-concentration VOCs, the concentrated purification treatment is more convenient, and the desorption gas discharged from the tail end treatment device S8 accords with the emission standard, and can be directly discharged to the atmosphere through the desorption gas output end. The flow path of the desorption gas in the exhaust line can be referred to as S61-S66 in fig. 2.
After the zeolite molecular sieve is heated to desorb VOCs, the zeolite molecular sieve is required to be cooled through a heat exchange unit in the VOCs treatment assembly to recover the state of the adsorbed VOCs, so that the regeneration of the zeolite molecular sieve is realized.
It can be seen that the deodorizing system according to this exemplary embodiment processes the odor in the form of the dust removing device S2, the desulfurizing device S3, and the VOCs processing assembly containing zeolite molecular sieve, which are matched with the purifying pipeline and the waste discharging pipeline, wherein the dust removing device S2 and the desulfurizing device S3 can remove the dust and the hydrogen sulfide in the odor, respectively, the zeolite molecular sieve in the VOCs processing assembly can efficiently remove the water-soluble and water-insoluble components in the odor, and especially, the processing efficiency of the water-insoluble components is greatly improved compared with that of the conventional deodorizing process, so that the emission concentration of the odor can be greatly reduced. And the adsorption, desorption and regeneration of the zeolite molecular sieve can be realized by matching with other parts, a purification pipeline and a waste discharge pipeline in the VOCs treatment assembly such as a heat exchange unit, so that the deodorizing system can be ensured to stably deodorize for a long time.

By providing the upstream flow distribution chamber S41 and the downstream flow distribution chamber S43, the airflow rate input into the molecular sieve filling chamber S42 and the airflow rate output from the downstream flow distribution chamber S43 can be reasonably distributed, thereby improving the adaptability of the deodorizing system.
In one embodiment, the VOCs treatment assembly may be provided with a plurality of the aforementioned VOCs treatment units S4, and the plurality of VOCs treatment units S4 are disposed in parallel in both the purge line and the waste discharge line. So, when purifying pipeline or discharging pipeline during operation, all can branch into multistage little amount of wind air current with the big amount of wind air current in the pipeline through the bleeder pipeline, the little amount of wind air current of multistage is handled to rethread a plurality of VOCs processing unit S4 one-to-one, both can promote absorption, desorption effect, can realize the absorption, the desorption of low-cost and low-traffic again.

Through the arrangement of the embodiment, not only the zeolite molecular sieve with the temperature raised by desorption can be cooled, but also the part of waste heat of the zeolite molecular sieve can be recycled, and the desorption gas is preheated before being heated, so that the energy consumption of the heating device S72 is reduced. The specific flow of the waste heat recovery and utilization is as follows:
The low-pressure low-temperature liquid-phase medium in the first heat exchange structure S44 is converted into a high-pressure high-temperature gas-phase medium by absorbing the residual heat in the zeolite molecular sieve with the temperature raised by desorption;
The low-pressure high-temperature gas-phase medium is pressurized by the compressor S53 and is converted into a high-pressure high-temperature gas-phase medium;
The high-pressure high-temperature gas phase medium enters a preheating device S71 (namely a second heat exchange structure) to preheat desorption gas, and the high-pressure high-temperature gas phase medium is converted into a high-pressure low-temperature liquid phase medium after heat exchange;
