Definitions
- the invention relates to a heat exchanger, the outer jacket of a vessel wall is formed, a cooling tube coil being located within the vessel wall, the Inside the vessel wall in the area of the cooling tube coil is provided with a heat and corrosion protection layer and where a thermal seal is attached to the upper end of the cooling pipe coil between the cooling pipe coil and the vessel wall.
- the heat exchanger can e.g. serve as syngas cooler.
- the flue gas / synthesis gas flowing through the inner gas space of a heat exchanger has at the bottom end of the boiler tube wall cage free access to the between the vessel wall or the pressure jacket and the tube cage formed annular space, so that in The gas and annulus approach the same pressure.
- the in the heat exchanger the as Synthesis gas cooler is used, arranged cooling surfaces extract part of the synthesis gas the sensible warmth, at the same time the solid components are cooled down and in separated in a water bath.
- the object of the invention is in a heat exchanger of the aforementioned Kind to provide heat and corrosion protection on the inner vessel wall, which at significantly reduced weight and reduced layer thickness granted good protection and the is also easy to install.
- the gas flowing through the gas space of the heat exchanger has free access to the Annulus, which is located between the tube cage and the vessel wall, so that approximately there is the same pressure in the two rooms.
- a cooling coil close to the wall with one in one Web sheet protruding into the water bath is arranged.
- one Sealing At the top of the cooling coil is one Sealing arranged, which is also the base of the invention Interior wall protection with ceramic fiber filler panels represents.
- the one above the top one Cooling tube attached wedge-shaped plate part is as so-called dust slide slope designed to possibly Avoid dust build-up in this area.
- the heat / corrosion protection layer from a variety of individual ceramic Filler panels joined together.
- the fiber filler panels which is made of a highly heat insulating Material are made on circumferential rings put on. These rings take up the vertical forces due to the weight of the panels and possibly Dust deposits on the face of the plates come.
- the fiber filler panels are in the radial direction on the inner vessel wall of the pressure jacket glued on.
- a suitable substructure e.g. B. Expanded metal, hex rust, perforated sheet u. a. upset to to give the adhesive an appropriate anchor.
- the Support rings are on the front with a Thermal insulation protection provided to prevent corrosion on the To prevent wrestling.
- ceramic Foam material can be applied that as continuous corrosion and heat protection along the Inner wall is foamed. Can on the support rings completely waived or the number of circulating Support rings can be significantly reduced.
- FIG. 1 shows the lower area of the synthesis gas cooler, where the gas to be cooled by the inner gas space (14) formed in a tube cage (11) flows down. Between the vessel wall (1) and the Tube cage (11) forms an annular space (12) so that approximately the same pressure in the gas (14) and annulus (12) prevails.
- the inner vessel wall (1) is through here protected against corrosion (16).
- This provides heat and corrosion protection for the inner wall (1) consistently given the pressure jacket; at the bottom Area of the heat exchanger, at the level of the cooling coils (9) with web plates (10), becomes a metallic Corrosion layer (16), above the cooling coils (9), a covering with ceramic fiber material (2) brought in.
- the seal (7) consists of in a known manner stacked fiberboard on a mounted on a cooling tube (9) welded web plate are. So-called through holes in the web plate Compression screws (8) with washers introduced that compress the fiberboard.
- a wedge-shaped plate part (15) has the Task to act as a dust slide slope to one to prevent dust build-up.
- the fiber filler panels (2) glued to the inner wall (1) of the pressure jacket.
- a suitable substructure (4) applied to the adhesive (5) a corresponding To give anchorage.
- the support rings (3) are with a Thermal insulation protection (6) provided to prevent corrosion to prevent the support rings (3).
- Fig. 2 shows in a section the structure of the heat and Corrosion protection layer on the inside of the vessel wall (1).
- Above the cooling pipe coil, not shown and the sealing are fiber filler panels (2) in Arranged segments and with support rings (3) Corrosion protection (6) held.
- the Fiber filler panels (2) by means of a substructure (4) and an adhesive (5) on the inside of the Vessel wall (1) attached.
