Abstract
The utility model relates to a seawater desalination using falling film evaporator technology made by using ring shaped node tube. The device fully uses ring shaped globoid design structure, which changes traditional straight pipe falling film evaporation mechanism and improves evaporation efficiency fatherly. The evaporator is suitable for multi-effect evaporation seawater desalination model, and belongs to seawater desalination technology field.
Description
Technical field
The utility model relates to a kind of sea water desaltination falling-film evaporator technology of utilizing ring-like bellows tube to manufacture, this vaporizer makes full use of axial ring-like spherule structure design, changed traditional straight tube falling film evaporation mechanism, further improved vaporization efficiency, this vaporizer is applicable to the desalting seawater through multi-effect evaporation pattern.Belong to field of sea water desalting technology.
Background technology
Seawater and brackish water are being carried out in the desalination process, routine techniques mainly contains distillation method, ion exchange method, dialysis, reverse osmosis membrane and cold method etc., wherein distillation method mainly adopts phase change technique to realize desalination, as modes such as multistage flash evaporation, low-temperature multi-effect evaporation and vapour compression.The topmost advantage of phase transformation class just is to make full use of renewable energy sources such as industrial exhaust heat or sun power, and can reuse the latent heat of evaporation and condensation, therefore is widely adopted in sea water desaltination.Vaporizer is the key part in such device, the desalination effect is played an important role, this class vaporizer generally adopts vertical tube falling film evaporation and horizontal tube falling film evaporation, horizontal tube falling film evaporation is the evaporation technique that new development is got up, and mainly utilizes liquid to condense and the separating of membranaceous mobile realization liquid phase and steam at extratubal falling film.It is generally acknowledged that level pipe is that the heat transfer coefficient of horizontal tube falling film evaporation is flash distillation or vertical tube evaporation 1.5-2 a times.But present horizontal falling film evaporation pipe mostly is metal straight pipe, the metal straight pipe welding combination of promptly adopting copper, aluminium, stainless steel, titanium alloy material to make, and this structure has only utilized two walls in the generating tube outside to realize falling film evaporation.Adopt and axially become wavy annular corrugated or bellows tube, can make full use of its globosity design, increased heat interchanging area on the one hand, improved intensity, changed interior heat transfer type on the other hand, the most important thing is to have changed falling film evaporation mechanism, therefore obviously improve than traditional straight tube vaporization efficiency.Annular corrugated or bellows tube is used widely in the heat exchange industry, belong to known technology, the heat exchange effect is apparently higher than straight pipe heat exchanger, if it is applied on the seawater desalination evaporators, then can on original technological achievement basis, further improve evaporation of seawater and desalination efficient.
Summary of the invention
Technical problem to be solved in the utility model is for sea water desalinating plant provides new vaporizer, further improves sea water desaltination output.
The alleged problem of the utility model is solved by following technical scheme:
Falling film evaporator with ring-shaped corrugated tube for seawater desalination is is mainly imported and exported and is formed by ring-like node generating tube, pipe top board, heating agent flow passage cover plate, heating agent, and heating agent flow passage cover plate, heating agent are imported and exported the end that is weldingly fixed on ring-like node falling-film evaporator respectively.
Described ring-like node generating tube is axially to become wavy metal bellows tube or metallic bellows.
The porous metal board member that described pipe top board is the ring-like bellows tube of bearing metal.
Described heating agent flow passage cover plate, heating agent are imported and exported the sealed interface that is respectively the turnover of falling-film evaporator heating agent fluid.
Described falling film evaporator with ring-shaped corrugated tube is selected the ring-like bellows tube of metal of sufficient amount according to the sea water desaltination steam output, its length requires decision according to desalination unit scale and evaporation area, and with each root pipe be welded on respectively the pipe top board on, afterwards with heating agent flow passage cover plate and welding of pipe top board or sealing, the heating agent interface can be located on the heating agent flow passage cover plate, its special feature is: falling film evaporator with ring-shaped corrugated tube is horizontally set in sea water desalting equipment or other thickening equipment, when the seawater through spraying or other need the bellows tube vaporizer of spissated liquid process sphere structure design, changed the mechanism that liquid becomes the freely falling body falling film evaporation, force fluid is in the ring-like bellows tube spherome surface uniform distribution and the film forming of condensing, when high temperature fluid during by the ring-like node generating tube of each root, interior heat-transfer fluid forms disturbance in pipe, its heat energy is evenly distributed to each node, accelerates the extratubal falling film evaporation.This vaporizer is applicable to that also doing evaporator assemblies in the absorption type air-conditioner refrigeration equipment uses except that suitable evaporation-type seawater desalination equipment uses.

Embodiment
Ring-like node generating tube 1 adopts metal straight pipe to process through plastotype, selects the ring-like bellows tube 1 of metal of sufficient amount then according to steam output, and its length is according to desalination unit and evaporation area decision; The ring-like node generating tube 1 of each root is welded on respectively on the pipe top board 2, and with heating agent flow passage cover plate 3 and 2 welding of pipe top board, heating agent interface 4,5 is located at respectively on the heating agent flow passage cover plate 3, as shown in Figure 1 afterwards.When making separately, vaporizer can be made into square, also vaporizer can be made conglobately, shown in Fig. 2,3, manage top board structure as vaporizer.
Adopt the beneficial effect of ring-like bellows tube evaporimeter to be, because ring-like bellows tube itself structurally Increased disengagement area, seawater or other liquid that need concentrate through spraying more are conducive at spherome surface Therefore the film forming of condensing evaporation obviously improves than straight tube falling film evaporation efficient. The utility model is except being applicable to Outside the desalinization, also be fit to liquid evaporation equipment that various need concentrate and establish as the absorption refrigeration air-conditioning Evaporator assemblies in standby uses, owing to use function identical without exception within protection domain of the present invention.
