    Process of cooling waste gas bend and apparatus for carrying out same, said process comprising removing concentrated heat at said bend by feeding coolant at an adjustable pressure through cooling channels longitudinally disposed along a selected sector of the cross-section of the bend, the channels being of equal flow cross-section within the entire circuit, said heat being reduced to a level prevailing in the cool sections of the bend portion of the casing (i.e. the cooler sections of the cross-section).

    专利说明:

    The purpose of the invention is to increase the cooling efficiency. This goal is achieved by the fact that in a device for cooling a gas outlet knee, the lateral surface of which is made in the form of sections of pipes located in the direction of the exhaust gases adjacent to each other and connected to the supply and removal of the cooling medium, rotary caps into coils connected in sections at the other end of the knee to the coolant inlet and outlet. The flow section of the cap is equal to the flow section of the coil. In addition, the device is equipped with a cooling flange, made in the form of spiral coils. FIG. 1 schematically shows the gas elbow; in fig. 2 - the side surface of the knee; in fig. 3 knee, view from tortsd from the side of the cooling flange; in fig. i and 5 - connection of two pipe lengths for about, development of a coil, two projections. The gas outlet leg 1 is turned 90. The greatest thermal load of the side surface 2 takes place in the sector oL. The side surface 2 of the collar to 1 consists of individual lengths of pipes 3 connected by a cap k so that they form a coil 5 and create a closed circulation loop. The inlet 6 and the outlet 7 of the cooling medium are made at the end of the hottest zone of the surface 2 for quickly removing heat from the respective section. Inputs 6 and outlets 7 of the individual circulation circuits (Fig. 2) are located at the upper end of the knee. The forced circulation goes through the distributor 8, to which the separate cooling circuits are connected, the flow area and the hydraulic resistance of each of which are selected according to the thermal conditions of the individual sections. The taps 7 are connected to the collector 9- Knee 1 is equipped with a chiller - flange 10, made in the form of spiral-shaped coils 11 and connected to one or several cooling circuits, so that no thermal stresses occur in the flange 10. The welded ends of the pipes 3 are connected by a cap C for turning the flow, the bore section 12 of the cap being equal to the cross section of each of the pipes connected by it. Adjacent to each other pipe walls are flat and parallel to each other and welded. The invention helps to prevent local overheating of the gas outlet bend and protects it from the occurrence of stress in it due to temperature differences. Claim 1. A device for cooling a vapor pipe, mainly a knee whose lateral surface is made in the form of exhaust gas tubes arranged in the direction of the exhaust gases adjacent to each other and connected to the supply and removal of the cooling medium, in order to increase the cooling efficiency, pipe sections are connected at one end of the knee by means of rotary caps e coils connected by sections at the other end of the knee to the inlet and outlet of the cooling medium. 2. The device. Under item 1, that is, that the flow section of the cap is equal to the flow section of the coil. 3- The device according to claim 1, about tl and which is provided in that it is equipped with a cooling flange made in the form of spiral-shaped coils. Sources of information taken into account. examination 1. The author's certificate of the USSR, cl. P23J 11/06, 1967. 2. The Federal Republic of Germany patent No. l4o8919, cl. 18t, pub. 1972.
