Embodiment 1

[0029] Such as figure 1 with figure 2 As shown, the evaporation tower provided by this embodiment includes: a tower body 1 having a cavity; a pair of atomizers, arranged on the tower body 1, having a mist outlet 2, suitable for generating atomization Material to be dried; a pair of air jets 4, which are relatively coaxially arranged on the tower body 1, suitable for injecting opposing high-temperature dry gas into the cavity, between the pair of air jets 4 A gas opposing zone is formed, and the mist exit path of the mist outlet 2 passes through the gas opposing zone, so that the high-temperature dry gas is mixed with the atomized material to be dried.

[0030] Since the pair of air jets 4 are arranged relatively coaxially, the two high-temperature dry gases entering the evaporation tower oppose each other to form a gas counteracting area, and the material to be dried atomized by the atomizer is atomized into fine droplets. On the one hand, In the hedging zone, the gas turbulenc...

Abstract

The invention relates to the technical field of solution evaporation drying, in particular to an evaporation drying system and an evaporation tower thereof. The evaporation tower comprises a tower body, at least one atomizer and at least one air jet hole, wherein the tower body is provided with a cavity; the at least one atomizer are arranged on the tower body and provided with mist outlets, and are suitable for generating atomized materials to be dried; and each pair of air jet holes is relatively and coaxially formed in the tower body, is suitable for jetting high-temperature dry gas hedgingmutually into the cavity, and an air jetting route of the air jet holes is crossed with a mist outlet route of the mist outlets, so that the high-temperature dry gas is mixed with the atomized materials to be dried. According to the evaporation drying system and the evaporation tower thereof, the evaporation efficiency and drying quality can be improved, and size of the equipment is reduced.

Description

Technical field [0001] The invention relates to the technical field of solution evaporation and drying, in particular to an evaporation drying system and an evaporation tower. Background technique [0002] Spray drying is a method applied to material drying. After the material to be dried is atomized, it is contacted with the hot flue gas phase, and the moisture in the material is quickly vaporized to obtain a dried product. The spray drying method can directly dry the solution and emulsion into powder or granular products, which can eliminate the evaporation and crushing process, and is widely used in the evaporation treatment of desulfurization wastewater. The evaporative drying device uses the principle of spray drying to atomize and spray materials into the evaporator tower to make contact with the dry flue gas passing into the evaporator tower to vaporize the moisture in the material and the dried product to settle to the bottom of the tower. [0003] In the spray drying proc...
