Embodiment Construction

[0067] figure 1 A slide valve is shown in cross section, which is used in a blast furnace plant for controlling a high-temperature flow, in particular for the control of a catalyst flow.

[0068] The closed position II of the spool valve is shown in Figures 1 to 4 in and open position I as shown in Figures 5 to 8 middle.

[0069] The fitting comprises a pipe part 10 lined with a refractory material 20 which is connected via a flange connection to a corresponding device part. Viewed along the flow direction S, in the upper part of the pipe section 10 the refractory material 20 tapers to form a funnel. At the end of the funnel is arranged a partition 11 which extends in the tube part 10 transversely to the direction of flow. The outlet of the funnel opens into a throttle opening 12 provided in the partition 11 , which is formed in a throttle plate 19 . The throttle plate 19 is screwed to a connecting plate 21 which is connected to the wall of the pipe part 10 . The orif...

Abstract

The invention relates to a sliding valve, especially for regulating a catalyser flow or similar high temperature media, said valve comprising a tubular section (10) and a diaphragm (11) which is arranged therein and comprises an inlet and an outlet (12a, 12b) through which a medium flows during operation. Said valve also comprises a sliding plate (13) which interacts with the outlet (12b) in order to regulate the catalyst flow and can be displaced into an open or closed position I, II. The sliding plate (13) is displaceably mounted by means of meshed guiding elements (14, 15) arranged on the tube side and on the plate side. The invention is characterised in that the tube-side guiding elements (14) are arranged upstream of the outlet (12b) in the flow direction.

Description

technical field [0001] The invention relates to a slide valve having the features of the preamble of claim 1 . Background technique [0002] Slide valves of this type are commonly used in FCC (Fluid Catalytic Packing) plants and are used to control the production rate of the plant, where the flow of catalyst (aluminum oxide, Al 2 o 3 ). [0003] Figure 14 The part on the left shows an example of such a slide valve used in industry. The slide valve has a pipe section in which is arranged a partition B with an orifice C, which is passed by a catalyst flow at a high velocity (10 m / sec.) at a temperature of about 720° C. during operation of the plant . orifice, such as Figure 14 As shown in , it is closed by a slide D, which is displaceably mounted transversely to the direction of flow. To open the spool move the spool from the Figure 4 The closed position shown in is moved to an open position, thereby partially or completely opening the orifice. [0004] To move the s...
