At present, exit collector is to open 10 ~ 30 millimeters sipes at corrosion resistant plate, on put cover plate, the outside silk screen that covers, there are many defectives in this structure: the ⑴ outer net can be torn because of not prison welding or external force breakage; ⑵ outer net string diameter is little, the meeting corrosion fracture; ⑶ outer screen distance is less, and the meeting adhesion is stopped up and caused the medium circulation not smooth; ⑷ it is damaged that outer net can be extruded distortion, and cause the solid particles such as catalyst in reactor, porcelain ball, foreign material to enter outlet and stop up export pipeline or valve; ⑸ outer net needs tight maintenance; ⑹ service life is short, potential safety hazard is large.
Distributor is that the sheet metal by 1.5 millimeters thick rolls into cylinder, apart from bottom of cylinder expansion joint is set, the expansion joint external diameter is greater than 3 ~ 5 millimeters of outside diameter of cylinder, riser inserts the circular hole of plate, the riser expansion joint is seated on the distribution plate plate naturally, bubble-cap is stamped to form by sheet metal, with connector itself and riser is fixed.This structure exists: after 1. the high temperature oil product enters reactor and gets to distribution plate plate or solid, produce coking.Find that in turnaround of unit the little protrusion on the plate particularly expansion joint one circle of riser has the hard coking, this phenomenon on the distribution plate of top more so.When 2. distribution plate overhauls back dress, riser can be as not installing for the first time safe smooth being installed on the plate, bad time dress, adamant occur and stop between installation, expansion joint and plate the phenomenons such as the slit is large, cause leakage, affect tightness and the distributivity of distribution plate.3. the easy Pressing Deformation of bubble-cap, percent defective is large.
Summary of the invention
Technical problem to be solved in the utility model provides the inner member that the coal tar hydrorefining device reaction device of again installation, long period safe handling is safeguarded in a kind of easy access.
For addressing the above problem, the inner member of coal tar hydrorefining device reaction device described in the utility model comprises several distributors that are located on the distribution plate plate and the exit collector that is located at reactor bottom; In described several distributors each includes bubble-cap, riser and is located at the destroyer of described riser bottom, it is characterized in that: described distribution plate plate be provided with described several distributors in each described riser several circular holes one to one, these several circular holes are equilateral triangle and arrange; Described bubble-cap is welded by cylindrical tube and circular top plate; Described riser assembles described destroyer and described bubble-cap by stay bolt, nut, connector; Described exit collector comprises cylindrical shell and the cover plate that places on the described cylindrical shell; Be evenly equipped with the slotted eye I of several two ends semicirculars in shape on the described cylindrical shell; Described cover plate is evenly equipped with the slotted eye II of several two ends semicirculars in shape along X direction; Be evenly equipped with several stiffeners in the described cylindrical shell, an end of this stiffener links to each other with described cover plate.
Described riser all links to each other with described distribution plate plate by expanded joint or welding.
12 ~ 14 millimeters apart from bottom places of described riser are thinned to 1.2 ~ 1.8 millimeters of thickness and form neck, and the external diameter after the cutting of bottom is greater than 0.1 ~ 0.3 millimeter of distribution circle bore dia on the described distribution plate plate; The neck of described riser is placed on the described distribution plate plate.
The width of described slotted eye I is 4 ~ 6 millimeters, and the groove center distance is 10 ~ 14 millimeters.
The width of described slotted eye II is 4 ~ 6 millimeters, and flute length is no more than 100 millimeters.
The utility model compared with prior art has the following advantages:
1, plate and riser are fixed in the utility model distributor, and splitting does not affect the tightness of riser and plate after the installation again, thereby have avoided the leakage problem after the maintenance secondary installing, have improved the validity that distribution plate re-uses; The simultaneously convenient practicality of inspection operation.
2, because the utility model exit collector has been removed the silk screen of outside covering, directly slot at cylindrical shell and cover plate, therefore, avoided reducing maintenance because of silk screen distortion, damaged leakage agent, the blocking pipe risk that produces.
3, owing to be provided with stiffener in the utility model exit collector, therefore, Effective Raise rigidity, strengthened load, simultaneously need not show great attention to maintenance, so that its life-span is consistent service life with housing.
