Background technology

With the development of industrial technology, mechanical vapor recompression technology (MVR), also known as direct heat pump techniques, usually with electricity Power is the energy, is returned in evaporator and is re-used using vapour compression machine promotion indirect steam pressure and temperature, to greatest extent The thermal energy being utilized in indirect steam, in industrial wastewater field, including wastewater from chemical industry, pharmacy waste water, high-salt wastewater, dyestuff are useless Water, electroplating wastewater etc.；Field of food industry, including fruit juice, milk, sucrose are concentrated by evaporation；Pharmaceutical field includes traditional Chinese drug inspissation, dimension Raw element, amino acid are concentrated by evaporation；Chemical industrial field, including evaporation, concentration, crystallization etc. have been more and more widely used, but In current MVR application systems, have the following disadvantages：

1, gas-liquid separator is except equipment body, and the floor space of equipment increases；

There is no defoaming device, feed liquid directly to flow down and easily generate foam when 2, detaching；

3, foam easily seals in vacuum pipe with gas, and extreme case may arrive at vapour compression machine, cause vapour pressure Contracting machine damages.

Utility model content

Technical problem to be solved in the utility model is to provide one kind for the above-mentioned prior art to have integral type gas-liquid The MVR evaporation structures of separated structure reduce the floor space of equipment, while can eliminate the foam of feed liquid generation.

The technical scheme in the invention for solving the above technical problem is：It is a kind of with integral type vapor-liquid separating structure MVR evaporation structures, including shell are disposed with steam-generating bank in the enclosure interior, are set at the central axes in the shell Be equipped with secondary steam pipe, gas-liquid separator be installed in the bottom of the shell, the bottom of the gas-liquid separator and shell it Between detachable connection, it is airtight cavity that the inner cavity constituted is surrounded by the shell and gas-liquid separator.

Preferably, the gas-liquid separator includes the deflector for having downward drainage function, and the deflector passes through along diameter Multiple gas-liquid separation chamber are formed to multiple baffles are arranged, material outlet is both provided in each gas-liquid separation chamber.

Preferably, the outlet port of the lower part of the shell, steam-generating bank is provided with defoaming device, the defoaming device Including case and gangboard, the case is open top and is connected to secondary steam bottom of the tube, and section is taper, the gangboard Arrange that foam is fallen to from evaporation tube on the gangboard of defoaming device from top to bottom along the outer surface of case, and along in certain gradient Gangboard flow downward.

Preferably, multiple partition boards are provided on the case, partition board is arranged along the gradient direction of gangboard.

Compared with prior art, the utility model has the advantage of：

1, gas-liquid separator and evaporator are integrated, reduces the space of equipment, passes through gas-liquid separator It is detachable between evaporator, easy to repair and cleaning；

2, defoaming device is set in the tube bank bottom of evaporator so that feed liquid is not fallen directly in liquid header, is prevented Foam seals in pipeline with gas, reduces the hidden danger damaged to vapour compression machine.

Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing embodiment.

As shown in Figure 1, the utility model is related to a kind of MVR evaporation structures with integral type vapor-liquid separating structure, packet Shell 1 is included, it is airtight cavity that the inner cavity constituted is surrounded by the shell 1, and steam-generating bank 2 is disposed with inside the shell 1, The top of the steam-generating bank 2 is cloth room 5, and secondary steam pipe 3 is provided at the central axes in the shell 1, and being used for will The steam discharge generated when evaporation is provided with defoaming device 4 in the lower part of the shell 1, and material is sent into shell 1 through cloth room 5 It is interior, and from top to bottom flowed along each evaporation pipe outer wall of steam-generating bank 2, it forms a film naturally under the effect of gravity, heating steam is by entering Mouthful enter each evaporation tube, exchange heat through tube wall with feed liquid, after heating steam heat-exchanging condensation form condensed water, condensed water along evaporation tube by Temperature improves rapidly after water outlet is discharged, and liquid film absorbs amount of heat, and the evaporation of negative pressure low-temperature boiling finally flow to steam-generating bank 2 bottom, and flash under the action of negative pressure, residual liquid is the concentrate of feed liquid, these concentrates directly flow down easily Foam is generated, pipeline can be sealed in gas, due to the effect of defoaming device, the foam generated in concentrate downflow processes can be automatic It eliminates, while gas-liquid separator 6 being installed in the bottom of shell 1, it is removable between the gas-liquid separator 6 and the bottom of shell 1 Unload formula connection.

Such as Fig. 2, shown in 3, the defoaming device 4 includes case 4.1 and gangboard 4.2, the case 4.1 be open top and It being connected to 3 bottom of double evaporation-cooling pipe, section is taper, and the gangboard 4.2 is arranged from top to bottom along the outer surface of case 4.1, Foam is fallen to from evaporation tube on the gangboard 4.2 of defoaming device, and is flowed downward along in the gangboard of certain gradient, in flow process In because gangboard effect can automatically rupture eliminate.In order to allow foam to be uniformly distributed flowing on defoaming device, in the cover Multiple partition boards 4.3 are provided on shell 4.1, partition board 4.3 is arranged along the gradient direction of gangboard 4.2, defoaming device is separated into multiple Region is defoamed.As can be seen from the figure there are gaps between 4.1 edge of case and shell 1 of defoaming device 4, therefore pass through Feed liquid after defoaming can downwards be fallen in gas-liquid separator 6.

Such as Fig. 4, shown in 5, the gas-liquid separator 6 includes deflector 6.1, which is vertebral body structure, and having will The effect that the feed liquid that defoaming device is fallen is collected to center, the deflector 6.1 are formed by being disposed radially multiple baffles 6.2 Multiple gas-liquid separation chamber 6.3, are both provided with material outlet 6.4 in each gas-liquid separation chamber 6.3, and ordinary material exports 6.4 In 6.1 center of deflector, the feed liquid fallen in this way from defoaming device can be expelled directly out by material outlet 6.4, and heated and steamed Vapour then flows up, and is discharged through secondary steam pipe 3, realizes gas-liquid separation.

The foregoing is merely a kind of preferable implementations of the utility model, are not intended to limit the utility model, All non-essential modification, replacement, improvement etc. made in the utility model spirit, should be included in the utility model Within protection domain.
