Abstract
The utility model discloses a large-scale flash vaporizer, which comprises a tower body in which a fluid channel is arranged, wherein a pressure reducing part is arranged at the upper part of the tower body, and a heating part is arranged at the lower part of the tower body; the heating part comprises a heating kettle and a heat exchange tube which is arranged in the heating kettle and connected with the fluid channel, and the heat exchange tube comprises a plurality of tubes which are arranged around the heating kettle in parallel; and each tube is connected in the fluid channel of the tower body from top to bottom. The heat exchange tube adopts tubes arranged around the heating kettle in parallel, so that the flow is larger, and the heat exchange is full; the amount of material which gathers at the center of the heating kettle can be reduced, so that the heat exchange of the material in the heating kettle is uniformly distributed, and the local temperature difference is smaller so as to improve production efficiency and heat utilization efficiency.
Description
Technical field
The utility model relates to the chemical industry preparation, relates in particular to a kind of large-scale flash distillation plant.
Background technology
Flash distillation plant is the chemical industry equipment of rapid gasification of a kind of convection cell and vapor-liquid separation, existing flash distillation plant comprises the decompression part on top and the warming portion of bottom, the boiling point of material is to reduce with pressure, flash distillation plant can be to heating behind the fluid pressure that enters, make fluid temperature (F.T.) be higher than boiling point under this pressure, fluid is boiling vaporization rapidly in flash distillation plant, and carries out two-phase and separate.What the warming portion of existing flash distillation plant adopted is that heat exchange coil is set in the heating kettle, the two ends of heat exchange coil are connected in the fluid course of flash distillation plant, in the existing heat exchange coil fluid pass through that speed is slow excessively, flow is little, cause production efficiency lower, autohemagglutination also appears easily.
The utility model content
The purpose of this utility model is to provide that a kind of fluid is big at the heating part flow, the sufficient large-scale flash distillation plant of heat exchange.
The technical solution of the utility model is: a kind of large-scale flash distillation plant, establish the tower body of fluid passage in comprising, tower body top is provided with the decompression part, the bottom is provided with heating part, described heating part comprises in heating kettle and the heating kettle heat exchanger tube that is serially connected with in the fluid passage is set, described heat exchanger tube is the many tubulations that are set up in parallel that are surrounded on around the heating kettle, and every tubulation is top-down to be serially connected with in the fluid passage of tower body.
Described every tubulation includes and is used for and material copper tube internal layer and the stainless steel skin that is used for contacting with heat medium.
Described heating kettle comprises inner heat exchanging chamber and is communicated with the import and export of the heat transferring medium of heat exchanging chamber that described heat exchanging pipe vertically wears at the heat exchanging chamber of heating kettle.
Described heating kettle center is provided with the central tube in the fluid passage that is serially connected with tower body, and described tubulation is located in around the central tube, is provided with flushing valve in the central tube.
Heat exchanger tube of the present utility model adopts and is surrounded on the heating kettle tubulation that is set up in parallel all around, flow is big and heat exchange is abundant, and can reduce the gathering of material at the heating kettle center, the heat exchange of material in the heat exchange still is evenly distributed, the bigger situation of local temperature difference can not appear, to enhance productivity and heat utilization efficiency.
In addition, tubulation of the present utility model adopts the stainless steel skin can improve corrosion resistance, and tubulation adopts the copper tube internal layer to play inhibition to the acrylamide product.
In addition, each tubulation of the present utility model is convenient to the even distribution of center tubulation around the central tube setting, and central tube can open when tower body washes, and flushing water can be reserved fast.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the structural representation of the tubulation among Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, the embodiment of large-scale flash distillation plant of the present utility model, establish the tower body 1 of fluid passage in comprising, advancing of fluid passage, outlet 6,7 are located at the top of tower body 1 respectively, the bottom, tower body 1 top also is provided with steam (vapor) outlet 8, tower body top is provided with the decompression part, the bottom is provided with heating part, described heating part comprises the many heat exchanging pipes 4 that are serially connected with in the fluid passage that are set up in parallel in heating kettle 2 and the heating kettle 2, heating kettle 2 comprises inner heat exchanging chamber and is communicated with the import and export 2-1 of the heat transferring medium of heat exchanging chamber, 2-2, described heat exchanging pipe 4 vertically wears at the heat exchanging chamber of heating kettle 2.Every heat exchanging pipe 4 includes and is used for copper tube internal layer 4-2 that contacts with material and outer 4-1 of the stainless steel that is used for contacting with the heat medium of heating kettle 2.Heating kettle 2 centers are provided with the central tube 3 in the fluid passage that is serially connected with tower body 1.Described every heat exchanging pipe 4 is top-down to be serially connected with in the fluid passage of tower body 1, and be located in central tube 3 around.Central tube 3 tops are provided with flushing valve 5, and flushing valve 5 is closed when flash distillation plant is worked, and the fluid in the fluid passage enters in each heat exchanging pipe 4, when large-scale flash distillation plant need wash, can open flushing valve 5, and flushing water can be reserved fast.
Embodiment of the present utility model is when work, material is entered by tower body 1 top inlet 6, feed liquid flows out from tower body 1 outlet at bottom 7, material steam is flowed out by steam (vapor) outlet 8, material is when flowing through heating part, because central tube 3 is obstructed, avoided material to concentrate on the center, material to around diffusion and be allocated in uniformly in each tubulation that ring establishes and carry out heat exchange with thermal medium in the heating kettle 2.In addition, each tubulation adopts the stainless steel skin to improve corrosion resistance.Each tubulation adopts the copper tube internal layer, and the copper tube internal layer can stop the acrylamide autohemagglutination that flows through in the production that is prepared acrylamide by acrylonitrile, and does not need to use polymerization inhibitor.
