[0019] Example 1

[0020] like Figure 1 As shown, it is the first embodiment of the utility model, which provides a new type of ridge-type indirect heat exchange equipment for solid powder, including a feed section cavity 2, the top of the feed section cavity 2 is connected with a feed pipe 1, the inner cavity of the feed section cavity 2 is provided with a heat exchange section cavity 4, one side of the inner cavity of the heat exchange section cavity 4 is provided with a ridge-type heat exchange element 5, both sides of the bottom of the feed section cavity 2 are fixedly connected with a discharge cavity 6, the bottom of the discharge cavity 6 is provided with a discharge valve 7, one side of the heat exchange section cavity 4 is fixedly connected with an inlet and outlet heat exchange medium pipe 3, the other side of the heat exchange section cavity 4 is fixedly connected with an inlet and outlet heat exchange medium manifold 8, and the inner cavity of the feed section cavity 2 is provided with a partition 9.

[0021] like Figure 1 As shown, the interior of the feed section cavity 2 is divided into multiple cavities that can be operated independently by a baffle. The equipment is subjected to the increased pressure generated by the deadweight of the material. The powder can fully contact the heat exchange surface during the self-flow process relying on its own weight, thereby solving the problem of uneven distribution of materials in an overall cavity. Multiple cavities can ensure stable flow of materials, reduce channeling, and plunger flow, thereby extending the residence time of materials in each heat exchange section cavity 4. At the same time, the material movement speed is low, which reduces wear. Each heat exchange chamber is independently designed, which is conducive to the use of heat exchange circulating water in series or in parallel, saving heat / refrigerant consumption. Each heat exchange chamber is both independent and interrelated, which is convenient for operation. According to different heat exchange requirements, it can be composed of multiple groups in series or in parallel, which is convenient for large-scale. A discharge valve 7 is set at the discharge port of the discharge cavity 6. After the material fills the tower body and the material level is established, continuous operation can be achieved. The residence time can be controlled by adjusting the valve speed of the inlet and outlet, and the residence time has a wide range of adaptability.

[0022] Example 2

[0023] Reference Figure 1 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0024] In this embodiment, the feeding section cavity 2 has a rectangular shape, and the inner cavity of the feeding section cavity 2 is divided by a baffle into four cavities that can be operated independently.

[0025] The appearance of the ridge-type heat exchange element 5 is an equilateral triangle ridge-type structure, and a plurality of ridge-type heat exchange elements 5 are arranged in a staggered manner.

[0026] like Figure 1 As shown, the interior of the feed section cavity 2 is divided into multiple cavities that can be operated independently by a baffle. The equipment is subjected to an increased pressure generated by the deadweight of the material. The powder can fully contact the heat exchange surface during the self-flow process relying on its own weight, thereby solving the problem of uneven distribution of materials in an overall cavity. Multiple cavities can ensure stable flow of materials, reduce channeling, and plunger flow, thereby extending the residence time of materials in each heat exchange section cavity 4. At the same time, the material movement speed is low, which reduces wear. The ridge-type heat exchange element 5 has an outer shape of an equilateral triangle or an isosceles triangle ridge structure. Compared with a circular tube of the same volume, the unit heat exchange area is increased. Under the same heat exchange area, the ridge-type structure is equivalent to reducing the tube bundle, thereby increasing the space for material flow and the space for heat exchange contact surface.

[0027] Example 3

[0028] Reference Figure 1 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0029] In this embodiment, each heat exchange chamber in the four chambers of the feed section chamber 2 is both independent and interconnected, and can be modularly connected in series and in parallel.

[0030] The buffer bin of the feed pipe 1 is divided into a plurality of feed openings by a baffle and a cone structure, and the feed openings correspond to the feed openings of the plurality of cavities in the inner cavity of the feed section cavity 2 respectively.

[0031] A discharge valve 7 is provided on the surface of the discharge cavity 6, and the discharge valve 7 is a rotary air-isolating valve.

[0032] like Figure 1 As shown, each heat exchange chamber in the four cavities of the inner cavity of the feed section cavity 2 is both independent and interconnected, which is easy to operate. It can be composed of multiple groups in series or parallel according to different heat exchange requirements, which is convenient for large-scale operation. The discharge valve can be a rotary air isolation valve, a ball valve and a butterfly valve. After the material fills the tower body and the material level is established, continuous operation can be achieved. The residence time can be controlled by adjusting the valve speed of the inlet and outlet, and the residence time has a wide range of adaptability.

[0033] When in use, the cavity of the ridge-type heat exchange equipment is a vertical rectangular structure. The main body consists of three parts: the feed section cavity 2, the heat exchange section cavity 4 and the discharge cavity 6. The material flows slowly from top to bottom due to gravity. The ridge-type heat exchange element 5 in the inner cavity of the heat exchange section cavity 4 is arranged in layers, staggered and evenly. It is the main component of the equipment. Each two adjacent layers of ridge-type heat exchange elements 5 are staggered. The ridge-type heat exchange element 5 is mainly used to provide the heat required for heat exchange and stabilize the bed temperature. The ridge-type heat exchange element 5 is an indirect heat exchange structure. The incoming heat exchange medium indirectly contacts the material to be dried through the wall of the ridge-type heat exchange element 5. The medium used can be steam, heat transfer oil, cooling water, etc. The interior of the feed section cavity 2 The baffle is used to divide the chamber into multiple cavities that can be operated independently. The equipment is subjected to increased pressure generated by the deadweight of the material. The powder can fully contact the heat exchange surface during the self-flow process relying on its own weight, thereby solving the problem of uneven distribution of materials in an overall cavity. Multiple cavities can ensure stable flow of materials, reduce channeling, and use plunger-type flow, thereby extending the residence time of materials in each heat exchange cavity 4. At the same time, the material movement speed is low, which reduces wear. The ridge-type heat exchange element 5 has an outer shape of an equilateral triangle or an isosceles triangle ridge structure. Compared with a circular tube of the same volume, the unit heat exchange area is increased. Under the same heat exchange area, the ridge-type structure is equivalent to reducing the tube bundle, thereby increasing the space for material flow and the space for heat exchange contact surface.
