Description

Hydraulic devices for unloading coke from delayed coking chambers, made in the form of a housing with nozzles and an axial nozzle, are known. However, the hydrodynamic properties of such devices are not satisfactory enough.

In the described device, to improve the dynamic properties of the jet, the binding to the four nozzles is made of bent re arc tubes terminating with straight tips, with dampers inserted inside them, the trunks of which are directed at an angle of up to, 10 ° to the horizon and at an angle of 90 ° relative to to each other. A cap with a conical seat for a cylindrical valve and openings for the passage of water and air is rigidly fixed above the tips. To distribute the flow of fluid into the nozzles and the nozzle with automatic alternating switching them into operation, depending on the difference in hydrostatic pressures, a spring-loaded cylindrical slide valve is inserted coaxially with it and inserted into another slide valve of similar design, but of a larger diameter, overlapping four windows in a glass rigidly attached to the body, the cut-out bottom of which partially overlaps the end ring annular plates;

FIG. 1 shows the described device; in fig. 2 is a view along arrow A in FIG. one.

A hydraulic device for unloading coke from delayed coking chambers consists of a body 1 having a lock 2 for connection with a rod, a three-channel nozzle 5, bent pipes 4 terminating with straight tips 5, dampers 6 inserted into the tips 5, and a mechanism 7 for distributing the supplied liquid such as water.

No. 148011-2. When the first barrel penetrates into the coke oven chamber, the water supplied to the housing 1 passes inside the zolotnik 8, flows around the conical seat 9 and through the holes 10 enters the internal cavity // nozzle 3. The exit from the channels 12 under high pressure, water destroys coke. Additional destruction of the latter is carried out with the help of the kerchiefs and the kerchiefs 13. For switching on the IB operation, after penetrating the first bore of the nozzles 5, an increased pressure is created in the cavity 14 of the housing 1, which increases the flow of water through the channels 12, its flow rate and velocity head. When the latter is increased, the spool S, overcoming the resistance of the spring 15, will go down and down the seat 9 to the saddle 9, blocking access to the cavity 16 of the housing for water. At the same time, the spool 17 will be lowered, squeezing its spring 18 and the opening window 19 in glass 20, through which water enters the pipes 4. During passage through the dampers 6, axial vortices are eliminated in it and the compact jets exit conical nozzles 21 , completes the destruction of coke.

The described device makes it possible to increase the efficiency of unloading coke from delayed coking chambers, facilitate the work of serving its staff, increase productivity, reduce unloading time and save large amounts of water.

Claims (2)

1. Hydraulic device for unloading coke from delayed coking chambers, consisting of a body with nozzles and an axial three-channel nozzle, characterized in that, in order to improve the dynamic properties of the jet using dampers, it is bound to four nozzles made from bent along the arc pipes terminated with straight tips with calms inserted inside them, the trunks of which are directed at an angle of up to 10 ° to the horizon and at an angle of 90 ° relative to each other and between which are rigidly fixed at the top along the vertical The axes are a three-channel nozzle with a conical seat for a cylindrical spool and four holes for the passage of water and air. 2. A device according to claim 1, characterized in that, in order to determine the flow of fluid to the nozzles and the nozzle with their automatic alternating operation, depending on the difference in hydrostatic pressures, a cylindrical spring-loaded bottom positioned in it is inserted into another taut spool, but of larger diameter, which overlaps four windows in a glass rigidly attached to the bottle, whose cut-out bottom partially overlaps the end ring areas of the spools. / 7 J3 See J, 21
