Embodiment
The utility model is to adopt the heat transfer plate pipe to be thinner efflux of solids with the material that relies on the downward continuous flow of gravity to carry out wall-type heat exchange.Respectively the runner of making, soda ash material and the heat transferring medium of heat transfer plate pipe and the structure formation of cooling alkali machine are described as follows:
One, the making of heat transfer plate pipe.
According to actual requirement, adopt steel-sheet thickness from 0.5mm to 3mm, to make the heat transfer plate pipe.According to actual heat transfer needs and process calculation, the heat transfer plate pipe be designed and sized to 500 * 500mm to 1200 * 1800mm.
The heat transfer plate pipe be by the two boards sheet through Laser Welding or resistance spot welding, stitch weldering all around, and welding baffling passage, then pressurising expand into and has certain thickness even Double side ripple shape, and its side welding up and down two import and export and take over.The heat transfer plate pipe adopts without the full Welding of pad, according to processing condition, can select stainless steel and other anti-corrosive alloy material.
Thickness range after the moulding of heat transfer plate pipe is between 8～40mm.
Two, the runner of soda ash material and heat transferring medium.
Can pass into water coolant, refrigeration agent, processing medium in the machicolated form inner flow passage of heat transfer plate pipe as the heat transferring medium that cools off.
According to inventory and physical property thereof, determine plate pipe quantity and plate tube spacing by process calculation, generally by 20～100 groups, spacing is that the heat transfer plate pipe of 20～50mm forms a branch of or a few bundle heat exchanger plates bundle group, is assembled in the fixing square casing.The form that arranges of single group heat exchanger plates bundle organizes that the heat exchanger plates bundle is staggered up and down to arrange form as shown in Figure 3 as shown in Figure 1.When many group heat exchanger plates bundles are staggered, leave the spacing of 300～600mm between the bundle of heat exchanger plates bundle and the bundle, as the section 14 that distributes again, to prevent feed blocking.Solid materials relies on the action of gravity of self, from top to bottom, passes through from forming outer flow passage between each heat transfer plate pipe, carries out wall-type heat exchange with from bottom to top heat transferring medium.
