Description
Technical field
The present invention relates to VOCs treatment technical field more particularly to a kind of sealing systems of exhaust gas enrichment facility.
Background technique
China's pharmaceuticals industry is environmental pollution rich and influential family, and wherein exhaust gas constituents are complicated, and contamination hazard is serious, and exhaust gas discharge is presented
Erratic behavior, so that developing adaptable exhaust treatment system seems particularly critical in pharmaceuticals industry waste gas pollution control and treatment field.
The purification method of VOCs mainly has absorption method, combustion method, biological clarification, corona method and plasma for purification method
Deng according to the type of VOCs, concentration, air quantity, recoverable value etc., selecting different processing methods, could preferably control
The pollution of VOCs.The case where investigating from existing market is learnt: either organic waste-gas purification, peculiar smell removal or solvent recovery,
Adsorption Concentration technology occupies very important status, has that construction cost is low, removal efficiency is high this is mainly due to absorption method,
The features such as thoroughly, low energy consumption, technical maturity for purification, energy recycling design, easy to spread practical.
The key application of absorption method, which first consists in, selects suitable adsorbent material as adsorbent, next is how to use
The adsorbent research and development adsorption plant that operating cost is low, removal efficiency is high.Currently, large amount of adsorption, the activated carbon adsorption being easily desorbed
Method is considered as an economically and reasonably process route.In practical application in industry, VOCs exhaust gas usually contains water vapour, activity
Charcoal absorption property is affected by aqueous vapor, regeneration is difficult, be also easy to produce secondary pollution, particularly the thermal current after adsorption saturation again
Fire easily occurs during raw, does not meet safety in production requirement now.
Currently, using the zeolite concentration rotating wheel that zeolite molecular sieve non-combustible, resistant to high temperature is researched and developed as adsorbent material as useless
The core component of gas enrichment facility is widely used in terms of organic exhaust gas adsorption concentration.Molecular sieve is by inorganic oxide
Composition has incombustibility, 2h is roasted at 900 DEG C, crystallinity still remains unchanged, therefore thermal stability is high, can lead to repeatedly
Heating is crossed to realize desorption and regeneration, and guarantees longer service life.Exhaust gas enrichment facility is by front and back cabinet and is located in cabinet
Between zeolite concentration rotating wheel composition.Core procedure is fixed on runner among the cabinet of front and back to keep its stabilization in assembling process
Rotation, and by sealing, it determines from the exhaust gas that air inlet enters cabinet and all passes through runner, without gas leak.Currently, often
The sealing means of use are that gasket is fixed on cabinet first, then by opposite between mobile change cabinet and runner
The mode of distance is sealed between runner and cabinet.This mode of operation can quickly adjust between cabinet and runner away from
From to achieve the purpose that sealing.
But this sealing means suffer from the drawback that firstly, being determined by exhaust gas properties to be processed, most cases lower box
Used material is 304 stainless steels, and the weight of the wheel being relatively large in diameter, cabinet is also quite large, is suitable to mobile box
Difficult；Secondly in most cases, it is contemplated that the reasons such as transport, often a complete runner is divided into several pieces of fans first
Piece is assembled after then transporting to scene, and it is inevitable locally to assemble unequal phenomenon in assembling process, at this time according to tradition
Sealing means can not accomplish the adjusting of partially sealed degree, generate so as to cause partially sealed not tight phenomenon.
