Patent application document CN201510153898.0 discloses a large-scale box-type high-temperature material heat exchanger. The large-scale box-type high-temperature material heat exchanger exchanges heat for high-temperature materials through a water-cooled box cover and a heat-exchange box. The tank cover and the wall of the heat exchange box are of a sandwich structure, which is a non-pressure-bearing type. Therefore, the cover of the cold water exchange tank and the heat exchange tank can only flow water, not the mixture of steam and water, so that hot water can only be produced by using the waste heat of high-temperature materials , unable to produce steam, waste heat cannot be efficiently utilized

Embodiment 2

[0047] Such as Figure 5~6 As shown: the difference between Embodiment 2 and Embodiment 1 is that the manifold 13 is arranged horizontally, both ends of the manifold 13 are closed, and the upper end of the inner heat exchange tube 11 communicates with the manifold 13 . A connecting pipe 16 is arranged between the collecting pipe 13 and the outer cylinder 2. The connecting pipe 16 is arranged vertically.

Embodiment 3

[0049] Such as Figure 7 As shown: the difference between embodiment 3 and embodiment 1 is that the confluence pipe 13 includes two horizontal parts and a bent part below, and the two horizontal parts are symmetrically arranged on both sides of the outer cylinder 2, and the two horizontal parts are close to the outer cylinder 2 One end communicates with the inner cavity of the outer cylinder 2, and the ends of the two horizontal parts away from the outer cylinder 2 respectively communicate with the two ends of the bending part. The folds are connected.

[0050] The feeding port 4 is arranged in the middle part of the inner cylinder 1, and the helical blades of the water-cooled spiral body are separated from the middle part, and the helical blades on both sides of the middle part are opposite in direction of rotation. When the water-cooled spiral rotates, it pushes the material toward both ends.

Abstract

The invention discloses a box type evaporator for waste heat utilization of high-temperature solid materials and belongs to the field of cooling equipment for the high-temperature solid materials. The box type evaporator is characterized in that an outer cylinderl (2) and an inner cylinder (1) are combined to form a sleeve type header; the lower end of a heat exchange box (7) is open; the sleeve type header seals the upper end of the heat exchange box (7); a feeding port (4) communicated with the inner cylinder (1) is arranged at the upper part of the sleeve type header; a water-cooled spiral distributor for conveying and cooling the materials is arranged inside the inner cylinder (1); a heat exchange cavity is arranged on the side wall of the heat exchange box (7) ad is communicated with an inner cavity of the outer cylinder (2); multiple isolating mechanisms are arranged inside the heat exchange box (7) in parallel and divide the heat exchange box (7) into multiple material channels; and the materials in the inner cylinder (1) fall into the material channels via discharge ports (6). Both the sleeve type header and the heat exchange box of the box type evaporator for waste heat utilization of the high-temperature solid materials can bear pressure, so that the evaporator can be directly applied to production of steam, and waste heat of the high-temperature materials is efficiently utilized.

Description

technical field [0001] A box-type evaporator for utilizing waste heat of high-temperature solid materials belongs to the field of cooling equipment for high-temperature solid materials. Background technique [0002] In industrial production, there are many high-temperature solid materials with high temperature, such as ash discharged from circulating fluidized bed, calcined coke formed by calcination of petroleum coke, semi-coke produced by dry distillation, powder coke formed by pyrolysis of pulverized coal, etc., they carry Waste heat can be recycled. Especially for the seed material produced by rotary kiln dry distillation, powdered semi-coke, and powdered coke formed by pyrolysis of pulverized coal, the output coke of a single set of equipment is large, and the remaining heat has more utilization value. Patent application document CN201510153898.0 discloses a large-scale box-type high-temperature material heat exchanger. The large-scale box-type high-temperature materia...
