Abstract
The utility model discloses a diaphragm type evaporator, which does not generate pressure suppression in irrigation washing, and is characterized in that the top of the diaphragm type evaporator is provided with an exhaust device. In irrigation washing, the exhaust device is opened for exhausting, and the evaporator is full of water, so the situation of incomplete cleaning is greatly improved, and the risk of affecting the service life of equipment due to pressure suppression is reduced.
Description
Technical field
The utility model relates to thin-film evaporator.
Background technology
The thin-film evaporator main purpose in aceticanhydride workshop is to reclaim aceticanhydride and the glacial acetic acid that contains in the heavy ends.Because contain the complicated ingredients such as tar of solid in the heavy ends, after operation a period of time, thin-film evaporator is dirty, the cleaning of just need stopping.When pouring water cleaning, the air in the thin-film evaporator can't be discharged, and causes its upper side not had by water logging, and owing to build the pressure, influences the service life of equipment.
The utility model content
The technical problem that the utility model solved provides a kind of pouring water and does not produce the thin-film evaporator that builds the pressure when cleaning.
The technical scheme of the utility model is at the top of thin-film evaporator exhaust apparatus to be set.
Wherein, said exhaust apparatus is the blast pipe of at least one band valve.
Said exhaust apparatus also can adopt one-way exhaust valve.
The beneficial effect of the utility model is: pour water when cleaning, open exhaust apparatus and carry out exhaust, make water fill evaporimeter, improved greatly and cleaned halfway situation, and reduced the risk that influences service life of equipment because of building the pressure.
Description of drawings
Fig. 1 is the structural representation of the utility model thin-film evaporator.
Be labeled as among the figure: thin-film evaporator 1, blast pipe 2, valve 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Thin-film evaporator as shown in Figure 1, the top of this thin-film evaporator 1 are provided with the blast pipe 2 of a band valve 3.After increasing this blast pipe 2, pour water when cleaning, open the valve 3 on this blast pipe 2 earlier, make water, carry out according to former cleaning step again from this pipeline overflow.Repeat several times, in the water that discharge the bottom till the free from admixture.Can discharge the air in the thin-film evaporator 1 more completely through blast pipe 2.
Claims (3)
1. thin-film evaporator, it is characterized in that: the top of this thin-film evaporator (1) is provided with exhaust apparatus.
2. thin-film evaporator as claimed in claim 1 is characterized in that: said exhaust apparatus is the blast pipe (2) of at least one band valve (3).
3. thin-film evaporator as claimed in claim 1 is characterized in that: said exhaust apparatus is an one-way exhaust valve.
