Abstract
The invention relates to the field of PTA (pure terephthalic acid) production technology, in particular to a conveying method of CTA (cellulose triacetate fiber) powder in a PTA (pure terephthalic acid) production device. With the adoption of the conveying method of the CTA powder, more than half number of the used nitrogen can be saved; and meanwhile, the CAT powder in an intermediate bin is served as the backup powder, so that the whole process of pulping of CTA can not be influenced once a spiral chain plate link is in fault or maintenance can not be influenced, and the whole PTA production technology can be continued.
Description
Technical field
The present invention relates to PTA production technology field, concretely, relate to the carrying method of CTA powder in a kind of PTA process units.
Background technology
The pure terephthalic acid is a primary raw material of producing poly-ester fibres, resin, film and container resin, is widely used in fields such as chemical fibre, container, packing, film production.The pure terephthalic acid in process of production, and is present, and what the conveying of CTA (crude terephthalic acid) powder was adopted is the method that wind send, and in course of conveying, the consumption of nitrogen is very big.
Summary of the invention
To above-mentioned technical matters, the purpose of this invention is to provide the carrying method of CTA powder in a kind of multipath, PTA process units of reducing nitrogen use level.
Technical scheme to be solved by this invention is following:
One of CTA powder transport way is to deliver in the storage tank through wind, adds back being transported in the making beating jar through spiral carrier bar of water stirring in the storage tank and pulls an oar; Another approach that the CTA powder is carried is to deliver in the intermediate bunker through wind; Intermediate bunker stores the CTA powder; When storage tank et out of order in the approach one or other problems, the CTA powder in the intermediate bunker is as stand-by storage, with CTA powder blanking to making beating jar interior making beating.
Adopt this CTA powder carrying method can save nitrogen use level over half; Simultaneously; CTA powder in the intermediate bunker is as subsequent use powder, and the process of whole C TA making beating is not received influence when spiral carrier bar link breaks down or keeps in repair, and whole PTA production technology still can be carried out.
Description of drawings
Fig. 1 is the structural representation sketch of the carrying method of CTA powder in a kind of PTA process units.
Reference numeral shown in Figure 1 is following: CTA powder 1, wind send 2, storage tank 3, carrier bar 4, making beating jars 5, intermediate bunker 6.
The specific embodiment
One of CTA powder 1 transport way is to send 2 to storage tank 3 through wind, adds back being transported in the making beating jar 5 through spiral carrier bar 4 of water stirring in the storage tank 3 and pulls an oar; Another approach that CTA powder 1 is carried is to send 2 to intermediate bunker 6 through wind; Intermediate bunker 6 stores CTA powder 1; When 3 et out of orders of the storage tank in the approach one or other problems, the CTA powder 1 in the intermediate bunker 6 is as stand-by storage 3, with CTA powder 1 blanking to making beating jar 5 interior making beating.
Claims (1)
1. the carrying method of CTA powder in the PTA process units, it is characterized in that: one of CTA powder transport way is to deliver in the storage tank through wind, adds water in the storage tank and stirs the back and be transported in the making beating jar through spiral carrier bar and pull an oar; Another approach that the CTA powder is carried is to deliver in the intermediate bunker through wind; Intermediate bunker stores the CTA powder; When storage tank et out of order in the approach one or other problems, the CTA powder in the intermediate bunker is as stand-by storage, with CTA powder blanking to making beating jar interior making beating.
