Petrochemical Filtration Devices
In petrochemical industry and fine chemical industry, chemical reactor will be used for catalytic reaction, and a large number of noble metal catalysts will be used in the process of catalytic reaction, which requires filtration and separation. The reactor can be divided into batch reactor and continuous reactor. Both reactors need a large number of noble metal catalysts. In the actual production process, catalyst leakage often occurs, resulting in increased cost and environmental pollution. Therefore, efficient filtration method is needed to separate catalyst filtration.
According to the different parameters such as temperature, flow rate, solid content, Ph value and viscosity, different filter devices are selected.
With the heavy quality of FCC feed-stock, the yield of catalytic oil slurry becomes larger and larger, because the slurry contains a certain amount of solid impurities (mainly composed of catalyst particles and colloid and asphaltene attached to the catalyst). More solid matter not only increases the erosion of pipelines and equipment, but also has the danger of blockage furnace drunken, which seriously affects the quality of feed-stock oil. Therefore, if the solid matter in the slurry can be filtered out, the quality of the slurry will be improved, and the application will become more extensive, thus increasing the added value of the slurry product. Slurry filter is a kind of solid-liquid separation equipment which can filter the solid matter above microns in the slurry.

How to improve jujube quality
It is necessary to determine the objects that need to be improved during the last fruit ripening period of the jujube fruit, and to determine quality varieties through visits and assessments, to avoid inadvertently improving the objects during the grafting period, blindly grafting, and sharing good and bad. If the whole park is grafted, this step is omitted. 1 scion preparation: First, determine the varieties and mother plants that need to be grafted. According to the above method, scion was collected on the better performing mother plant. The scions are best collected on the annual jujube trees. The scions should have buds and eyes full and no juvenile disease and quarantine objects. The thickness is 0.4-0.8 cm, leaving 1 cm on buds and 4-5 cm under buds. After the scion was collected, the wax was sealed and the raw materials for sealing the scion were industrial paraffin. Wax temperature when sealing wax should not be too high, with 70 °C ~ 80 °C is appropriate, too easy to scald buds, phloem and formation scion layer, and not easy to store. After scion sealing, if it is not used immediately, it should be stored in cold storage and stored moist. 2 Grafting: There are two kinds of grafting methods that are most suitable for improving inferior varieties of jujube trees: splicing and cutting. Jujube peeling after skin grafting grafted than grafted survival rate is higher. There are three points to follow: to cut the surface to be flat, to form a layer to be aligned, and to be tight. The skin graft is also called the skin, this method is easy to learn, easy to operate, is a method of grafting survival rate is high, skilled grafted graft survival rate can reach 99%, but with the skin grafted improved varieties must wait until jujube After the skin can be carried out. 3 after the management: After grafting due to the scion and rootstock formation layer of healing process, the dormant buds of the rootstock itself will sprout rapidly after stimulation, thus resulting in the competition between the scion and rootstock nutrient, must be promptly wipe buds, The nutrients are used to supply scion concentrates to promote the healing of scion and rootstock. Generally, the buds are wiped every 3 to 5 days. Fertilizer management should generally be carried out before grafting, in order to promote the viability of rootstocks, to activate the formation of rootstocks, and to enhance the healing capacity of meristems in the formation layer, thereby increasing the survival rate.
