Abstract
The utility model belongs to the field of the waste gas recycling device, in particular to a flash steam recycling device for a flash drum. The flash steam recycling device for the flash drum comprises two flash drums, wherein the liquid inlet of the first flash drum is connected with a liquid inlet pipe; the steam outlet of the first flash drum is connected with the vapor inlet of the second flash drum; liquid outlets on the bottoms of the two flash drums are all connected with a liquid storage drum; and steam outlets on the upper part of the second flash drum and the upper part of the liquid storage drum are all connected with an emptying pipe. The flash vapor recycling device is characterized in that the steam outlet on the upper part of the second flash drum and the steam outlet of the upper part of the liquid storage drum are connected with the steam inlet of a triple effect evaporator via a steam recovery pipe; and the steam recovery pipe is provided with a steam ejector. According to the flash steam recycling device, a great quantity of waste gas generated by the flash evaporation of the two flash drums is recovered and is conveyed to an evaporation concentration post by the steam ejector, the flash steam is fully utilized, the evaporation concentration post can operate under the condition of little steam even no steam, so that the steam consumption is greatly reduced, and good economic benefit is brought for the production enterprise.
Description
Technical field
The utility model belongs to waste vapour recycling device field, is specifically related to a kind of flash tank flash steam re-use device.
Background technology
In food-processing industry, the liquefaction operation can be carried out flash distillation to material through flash tank, can produce a large amount of flash distillation waste vapour in the flash process; These waste vapour all were not add utilization in the past; Directly be discharged in the air, serious waste the steam resource, manufacturing enterprise has also been caused economic loss.
The utility model content
The purpose of the utility model is to solve in the existing present food-processing industry; Produce a large amount of flash distillation waste vapour in the flash process, directly emptying, the defective of waste steam resource; Provide a kind of this part waste vapour waste heat that utilizes to concentrate material, practice thrift the flash tank flash steam re-use device of steam resource.
The utility model is realized through following technical scheme:
It is a kind of flash tank flash steam re-use device; Comprise two flash tanks; The inlet of first flash tank is connected with feed tube; The steam (vapor) outlet of first flash tank is connected with the steam inlet of second flash tank, and the liquid outlet of two flash tank bottoms all is connected with fluid reservoir, and the steam (vapor) outlet on the second flash tank top and fluid reservoir top all is connected with evacuated tube; The steam (vapor) outlet that it is characterized in that the second flash tank top and fluid reservoir top is connected with the air intake of triple effect evaporator through the Steam Recovery pipe, and said Steam Recovery pipe is provided with steam jet ejector.
A preferred version as the utility model: be equipped with Pneumatic butterfly valve on evacuated tube and the Steam Recovery pipe.
The utility model reclaims a large amount of waste vapour that two flash tank flash distillations produce; Be delivered to the evaporation and concentration post through steam jet ejector again; Made full use of the flash distillation waste vapour; Make the evaporation and concentration post reach few living steam even do not have the operation of living steam, practiced thrift steam consumption greatly, for manufacturing enterprise has brought good economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Shown in figure: 1 feed tube; 2 first flash tanks; 3 second flash tanks; 4 evacuated tube; 5 Pneumatic butterfly valves; 6 Pneumatic butterfly valves; 7 Steam Recovery pipes; 8 steam jet ejectors; 9 triple effect evaporators; 10 give birth to steam input pipe; 11 fluid reservoirs.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further elaboration.
As shown in Figure 1: the inlet of first flash tank 2 is connected with feed tube 1; The steam (vapor) outlet of first flash tank 2 is connected with the steam inlet of second flash tank 3; The liquid outlet of two flash tank bottoms all is connected with fluid reservoir 11; The steam (vapor) outlet on second flash tank, 3 tops and fluid reservoir 11 tops is connected with evacuated tube 4, Steam Recovery pipe 7 respectively; Steam Recovery pipe 7 is connected with the air intake of triple effect evaporator 9, and said Steam Recovery pipe 7 is provided with steam jet ejector 8, is respectively equipped with Pneumatic butterfly valve 5,6 on evacuated tube 4 and the Steam Recovery pipe 7.
When the utility model liquefaction operation ran well, Pneumatic butterfly valve 5 was closed, and Pneumatic butterfly valve 6 is opened; Flash-off steam collects through pipeline; The waste vapour that fluid reservoir 11 produces also collects through pipeline, incorporates Steam Recovery pipe 7 into, for preventing the steam suck-back; Change fluid reservoir 11 feeding manners into bottom feed, the top charging aperture is shut with iron plate.The steam of collecting leads to the evaporation and concentration post through Steam Recovery pipe 7, goes to triple effect evaporator 9 through steam jet ejector 8, and the living vapor mixing with giving birth in the steam input pipe 10 heats up to triple effect evaporator 9 together, reaches concentrated material, practices thrift the purpose of steam.
When the liquefaction operation is stopped, open Pneumatic butterfly valve 5, the emptying residual gas is closed Pneumatic butterfly valve 6, to avoid influencing because of no steam the vacuum of triple effect evaporator 9 inside.
Use the utility model, made full use of the flash distillation waste vapour, make the evaporation and concentration post reach few living steam even do not have living steam operation, practiced thrift steam consumption greatly.
