Definitions

  • a cooler for the passage of a regulable partial current of heat carrier in a reaction vessel includes a cooler housing having longitudinally spaced inlet and outlet connections.
  • a plurality of cooling tubes extend longitudinally through the housing and the interior of the housing is divided into a flow path along and around the tubes from the inlet to the outlet and a control flow through a by-pass extending from the inlet to the outlet on the exterior of the tubes but within the housing.
  • the coolant is circulated through a central coolant inlet tube which extends centrally within the tube bundle for flow from the chamber defined at the far end upwardly through the tubes to an opposite chamber for removal.
  • the by-pass flow is regulated by means of a slide valve which maybe slid along the by-pass passage to divert a portion of the inlet flow through the inlet so that it flows directly through the by-pass to the outlet and is not affected by the cooling tubes.
  • the circulation to the .cooler may be from the interior of the reactor to the inlet and from the outlet back into the reactor. Alternai tively, the flow may be through an annular conduit extending around the reactor from the outlet of the cooler and thence downwardly on the exterior passage around the annular outlet back to the inlet.
  • This invention relates in general to the construction of coolers and in particular, to a new and useful cooler for the passage of a controlled partial amount of heat carrier which is circulated in a reaction vessel.
  • a reaction vessel for carrying out chemical reactions such as contact furnaces
  • heat is transferred to a heat carrier preferably a fused salt bath.
  • the heat carrier is circulated by means of a pump in the reaction vessel and a cooler is provided to maintain constant temperature conditions.
  • the heat generated in through reaction vessel is delivered to the water circulated through a nest of tubes in the cooler.
  • the entire heat carrier flows in a cycle from the reaction vessel into the cooler and back again.
  • the control of the temperature by eliminating heat is effected by the amount of feed water supplied to the cooler.
  • the heat carrier such as a salt bath which is circulated in the reaction vessel
  • a partial current which is conducted through a cooler and back again into the reaction vessel.
  • This partial current or flow mixes with the rest of the salt bath.
  • the connections for the exit and reentry of the partial current are arranged in the reaction vessel at points where a pressure difference exists. With this latter arrangement, an additional circulation pump is not required for the partial current flow.
  • the first system described above has the disadvantage that the evaporation and superheating of the water takes place by necessity in a tube field. At the points where the water is transferred in the steam phase, high alternating thermal stresses are produced which frequently lead to tension cracks.
  • coolers which include a slide valve control for regulating the partial current flow of the cooling medium.
  • Such a design has disadvantages. With a low load of the reaction vessel there is little heat to eliminate. The amount of salt is then greatly throttled by the slide valve. This produces a correspondingly smaller amount of heat carrier flow and it causes the heat carrier to flow relatively slowly through the cooler. Due to the longer stay, the salt bath is greatly cooled. The salt bath, which has been reduced significantly in temperature, thus returns to the reaction vessel and is likely to cause trouble in the operation of the vessel. In addition, the materials are highly stressed'by the great temperature differences due to thermal stresses.
  • the slide valve of the cooler In those instances, where a great amount of heat has to be eliminated from the reaction vessel the slide valve of the cooler must be opened wide. The partial amount of the heat carrier flowing through the cooler is great so that the stay period in the cooler is short. The salt bath thus has a relatively high temperature at the outlet of the cooler. A larger amount of salt bath with a small reduction of temperature is therefore returned into the reaction vessel. Since the amount ofheat to be eliminated is inversely proportional to thetemperature difference betweenthe cooler inlet and the cooler outlet it is not possible to achieve the desired plant performance. In addition, the cooling area of the-cooler cannot be calculated exactly because of the abovedescribed conditions.
  • the partial amount of the salt bath returning to the reaction vessel has substantially the very low temperature of the water in the cooler in all load ranges.
  • the flow distribution in the reaction vessel is also distorted by the fact that the partial current temporarily branched off from the circulation in the reaction vessel and flowing through the cooler is changed during the regulation by the slide valve.
  • the disadvantages of the prior art are substantially eliminated by providing a cooler having a by-pass which serves for the tempoe rary subdivision of the constant partial current of the heat carrier which may be branched off from the reaction vessel into two parallel flowing and then combined currents, or streams, of which only one is directed along side the cooling tubes.
  • the control of the amount of partial current flow through each path is controlled by a control element designed as a slide valve which is arranged so that movement thereof will divert a larger or smaller partial cross section of the inlet flow stream into the by-pass with the remainder being directed for flow into assocation with the cooling tubes.
  • the construction of the cooler includes a nest of cooling tubes which are arranged eccentrically to the longitudinal axis of an associated outer shell or housing wall.
  • the tubes are offset from the axis to provide a wider part of an annular or ring shaped by-pass at one side adjacent the inlet and the outlet openings for accommodating a control member suchas a slide valve.
  • the construction preferably includes an annular passage around the tube nest which is divided in an axial direction by a plurality of disc elements which permit the flow of a partial current stream from the inlet in a transverse direction through the tube nest and then axially around the spaced disc members which provide baffle elements along and around the tubes. The partial stream is discharged at the other end through the outlet.
  • the discs define on their inner and outer circumferences a flow cross section similar to a coil shaped guide for the partial flow of the heat carrier to be cooled and the internal wall portion or inner shell of the cooler permits an annular flow ofa partial stream outside of the tubes directly to the outlet -so that this part of the stream is not cooled.
  • an object of the invention to provide an improved cooler construction for use with a reaction vessel which includes a housing defining a partial flow path from an inlet through and around cooling tube elements and another partial flow path for bypassing the flow through the tubular elements which is regulated by the movement of a control member and which advantageously includes a housing formed by a tube bundle which is eccentrically positioned within a cylindrical housing shell in order to define a passage for a movement of the slide valve for controlling the partial flows.
  • a further object of the invention is to provide a reactor cooling system having an improved means for flow control and regulation of a circulating medium for cooling the reactor.
  • a further object of the invention is to provide a cooler and a reactor system which are simple in design, rugged in construction and economical to manufacture.

  • the tube sheet 4 and the hood 6 define a cooling liquid outlet chamber 50 and the tube sheet 3 and hood 5 define a reversing chamber 52.
  • the tube sheet 2 is surrounded, in an intermediate area between an inlet 14 and an outlet of shell 1, by an inner shell 7.
  • a disc member or partition baffle 8 extends transversely between the nest of tubes 2 and to the exterior wall of the outer shell 1 at a location at the top of the inlet 14 but not in a slide valve slot area of a by-pass which extends from the inlet 14 directly to the outlet 15 between the inner shell 7 and the outer shell 1.
  • a plurality of similar discs 9 and 10 which do not extend to the interior wall of the outer shell 1 but only to the inner shell 7 as well as the disc 8 have central openings for the passage of a partial flow stream therethrough.
  • the discs 8, 9 and 10 are alternately arranged with discs 11 and 12 which engage around the periphery of a coolant medium supply tube 13 which extends centrally through the nest of tubes 2 and communicates at its inner end with the reversing chamber 52.
  • the discs 11 and 12 do not extend outwardly to the inner shell 7 but leave a flow passage between the shell and the discs.
  • the first partial flow is from the inlet in the direction of the curved arrows and through and around the nest of tubes 2 and along the tubes to the outlet and then transversely out through the outlet.
  • the cooling medium which flows through the tube 13 and into the reversing chamber 52 flows through the tubes of the nest 2 and to the discharge chamber 50 and out through an outlet tube 16.
  • the cooler 23 is advantageously arranged vertically and the outlet 15 is aligned vertically with the inlet 14 and connected into the outer shell 1 in the area of the widest interior space between the inner tube shell and the interior of the wall of the outer shell 1. This is the area of the by-pass 20 and in this by-pass a box-shaped slide valve 17 is movable either upwardly or downwardly by actuating means (not shown) connected to a rod 18.

  • the valve 17 has a curved wall 17a which may be oriented in the flow stream of the heat carrier to provide an even diversion of this stream to the by-pass 20 in accordance with operational requirements.
  • the partial current, which flows in the direction of the arrow 56 through the bypass is practically not influenced by the cooling medium circulated through the nest of tubes 2. This flow is combined with the partial current flowing in the direction of the arrow 54 through and over the tubes 2 at the location of the outlet 15.
  • the design of the cooler 23 has several operating advantages in addition to its simple construction.
  • the amount of circulating heat carrier flowing through the salt bath cooler and thus also the circulating amount of the flow distribution in the reaction vessel are constant in all load ranges.

  • the slide valve At a temperature deviation of substantially zero the slide valve is at the bottom and the entire amount flows through the system without coming into the range of the cooling tube nest 2.
  • Under load the slide valve 17 is moved to the top position in which substantially the entire stream is diverted into heat exchange relationship with the tubes and there is very little or no flow through the by-pass 20.
  • the temperature difference is established between the salt bath inlet 14 and the salt bath outlet 15 after the two temporarily separated partial flow streams are mixed at the outlet 15.
  • the nest of tubes 2 can be designed as an evaporator or as a gas heater or as an evaporator with a series connected superheater.
