Definitions
- the invention relates to a heat exchanger for cooling Fission gas with the features of the generic term of Claim 1.
- a heat exchanger is from the GB-A-1 504 361.
- the cracked gas is released by a thermal cracking of Hydrocarbons produced in a cracking furnace.
- This Cracking furnaces are heated with a number from the outside Provide canned tubes through which the used Hydrocarbons with the addition of water vapor become.
- the cracked gas generated leaves the can with one Temperature of about 800 to 850 ° C and needs for stabilization its molecular composition cooled very quickly become. This is done in a cracked gas cooler by a Heat transfer from the fission gas to evaporating, below high pressure water.
- Cracked gas coolers are known in which each one is made of the can coming out of the cracking furnace with a separate one
- the cracked gas cooler is connected to one or more pipes can own, enclosed by a common coat or are designed as double pipes. Since the from the As a rule, the cracked tubes emerging from the cracking furnace are linear can be arranged at a relatively short distance from one another all cracked gas coolers in one module in the form of a Linear cooler can be summarized.
- the supply and discharge of the Cooling medium takes place at the ends of the pipes Water chambers that are oval or tubular can.
- the double tube heat exchanger known from GB-A-1 504 361 for cooling cracked gas contains oval tubes Water chambers. Several oval tubes are gas tight Floor welded together, which is a gas entry chamber completes. The inner tube and the inner tube under formation an outer tube surrounding an annular gap are on each other welded into the oval tube on opposite sides. The interior of a water chamber stands with the annular gap of all connected double pipes in connection.
- From US-A-5 035 283 is a shell and tube heat exchanger known in which the cooling tubes of a common jacket enclosed and in a tube plate provided with cooling channels are welded in.
- the tube plate is with the inside of the Provide sheaths open turns, which with the Cooling channels are connected and the cooling pipes surrounded concentrically.
- the cooling tubes in each row of tubes penetrate the cooling channels.
- the invention is based, the water chamber of the task Generic heat exchanger to design so that none Material overheating of the surfaces involved in the heat exchange occur that a defined flow of entering Cooling medium is set and that the water chamber the high Presses the coolant withstands and inexpensively is to be produced.
- the pressure of the Cooling medium on a relatively narrow annular, the Bottom of the depression-representing surface, the Outside diameter not the inside diameter of the outer tube significantly exceeds. Due to the small size of the through the pressure of the soil loaded with the cooling medium only needs it to be provided with a small wall thickness. This minor Wall thickness allows good cooling of the temperature-loaded Soil through the cooling medium so that material overheats can be avoided. Outside the distance from each other The water chamber retains the intended recesses original thickness of the solid piece, so that the Water chamber is stiff enough in itself to be without additional Reinforcements to withstand the high pressure of the cooling medium.
- the recesses can be made into the solid piece by a simple mechanical processing such as drilling and milling bring in, reducing the effort for the production of Water chamber is reduced.
- each cooling tube can individually from the cooling medium can be controlled, resulting in a better distribution of the Cooling medium on this results in a cooling tube.
- the cross section circular depression created especially in connection with a tangential supply of the cooling medium a rotating Coolant flow, which ensures good cooling of the floor and an undesirable deposition of particles from the Coolant does not allow. Any existing particles will be the cyclone principle in the rotating flow near the Wall of the recess held and can by the further Borehole leading to the outside is removed during operation become.
- a cracking furnace In a cracking furnace is implemented by Hydrocarbons generate a fission gas with water vapor.
- the Cracking furnace is provided with can 2, from the outside are heated and flowed through by the feed. That the Can 2 with a temperature of 800 to 850 ° C leaving cracked gas enters a cracked gas cooler 3 one that is in the immediate vicinity above the cracking furnace is arranged.
- this cracked gas cooler 3 In this cracked gas cooler 3, the molecular Composition of the cracked gas due to a sudden cooling in the Heat exchange with evaporating, under high pressure Stabilized water.
- the cracked gas cooler 3 consists of one or more cooling tubes 4, which are arranged in a row next to each other, that each cooling tube 4 is assigned to and in a canned tube 2 axial extension.
- the inside diameter of The can 2 and the cooling tube 4 are, as shown, customary same size.
- the cooling pipes 4 open into a gas manifold 5 on.
- Each cooling tube 4 is ring-shaped Intermediate space surrounded by an outer tube 6. At both ends the outer tubes 6 are water chambers 7, 8 for the supply and Removal of the cooling medium is provided.
- each can 2 is widened like a fork.
- an inner, the tube section 9 forming the extension of the can 2 and an outer tube section 10, both at one end are interconnected.
- the outer tube section 10 is on the lower water chamber 7 welded.
- the inner one Pipe section 9 of the canned tube 2 is small axial distance from the cooling tube 4.
- the gap between the inner pipe section 9 and the outer Pipe section 10 is made of a layer 17 filled with heat-insulating material.
- the water chamber 7, 8 is made of a solid, seamless, strip-shaped piece. This piece is in one Distance from one another in cross section circular depressions 11 incorporated, the number of which corresponds to the cooling tubes 4.
- Each cooling tube 4 has its own depression 11 assigned.
- the outer tube 6 is on the can 2 opposite side welded to the water chamber 7.
- the inside diameter of the Outer tube 6 corresponds to the diameter of the reinforcement 11.
- the recess 11 can consistently this diameter exhibit.
- the deepening can also be done in the middle area be widened, the diameter of the recess 11 being approximately by the width of the space between the cooling tube 4 and the outer tube 6 can be larger than the inner diameter of the Outer tube 6.
- the depression 11 is so deep that the water chamber 7, 8 forming piece incorporated that an annular bottom 12 with a small remaining wall thickness remains.
- this floor 12 is the cooling tube 4 welded.
- the area of the annular Bottom 12 is limited by the outer diameter of the Cooling tube 4 and the diameter of the recess 11th
- Each depression 11 opens out at the level of the bottom 12 preferably tangentially into a bore 13.
- the holes 13 are each via a connecting piece 14 with a Supply line 15 connected to the cooling medium.
- the Coolant passes through the bore 13 at high speed into the recess 11 and generates a rotating flow around the cooling tube 4. This flow ensures good cooling of the bottom 12 of the recess 11 and thereby prevents one Deposition of particles on the floor 12, which leads to a harmful local overheating.
- the depression 11 is provided with a further bore 16, which is led to the outside at the level of the bottom 12. Through this further bore 16 can the particles that are in the Well 11 are and with the flow of the cooling medium rotate during the operation of the cracked gas cooler 3 be removed.
- the others are Bores 16 connected to a line 18.
- This line 18 is equipped with a drain valve, not shown. By a brief, sudden opening of the drain valve can remove cooling medium with particles contained therein become.
- the holes 13, 16 described can be used as Inspection openings can be used by passing through them an operational shutdown, an endoscope in the recess 11 is introduced. With the help of these endoscopes, the Check the condition of the recess 11.
- Fig. 1 is a cracked gas cooler 3 with three cooling tubes shown. Without leaving the principle according to the invention, can the cracked gas cooler also more than three or only one Cooling tube included.
