It is not connected to the feed bin of the charging door and adsorbent, improves charging efficiency.
Above method curing molding in storage tank by absorbent particles, one side padding facility, is on the other hand inhaling
By absorbent particles curing molding in attached dose of activation process, adsorbent location structure is formed, support and position-limit mechanism is eliminated, carries
High adsorption efficiency.Compared with prior art, it breaches and absorbent particles is fixed on by a certain model using support plate and fixed plate
Interior pattern is enclosed, also breaches and is arranged in the prior art by adsorbent pre-molding, again by formed absorbent outside tank body
Pattern.
The advantageous effect generated using above-mentioned technical proposal is：（1）Filling mode of the present invention is simple, quick, has filled
Bi Hou completes curing molding while adsorbent activates, simple for process, reduces the difficulty of processing of ANG storage tanks；（2）Absorption
Agent curing molding avoids colliding in transit, rub, stable structure, and it is not necessary that adsorbent support component is arranged, tank body is certainly
Heavy and light, unit weight are relatively high.
