Description
Technical field
The present invention relates to a kind of UTILIZATION OF VESIDUAL HEAT IN system, especially relate to a kind of DPC reaction distillation column overhead heat recovery steam device.
Background technology
In chemical process, the purity of organic solvent is required more and more higher. Need to process multiple mixed solvent simultaneously. Wherein often meet multiple mixed solvent and azeotropic, separation be a big common technology difficult problem. The separated from solvent usually with many units azeotropic properties, repeatedly need to be separated rectification and purification repeatedly step by step by rectifying distillation tower.
What current distillation tower was not all made laughs utilizes the heat energy of its inside, so that energy utilization rate is not high, therefore causes cost to remain high. Therefore existing market needs a kind of DPC reaction distillation column overhead heat recovery steam device, it is to increase the heat utilization rate of distillation tower, reduce enterprise cost.
Summary of the invention
The present invention is directed to deficiency of the prior art, it provides a kind of DPC reaction distillation column overhead heat recovery steam device, simple and reliable for structure, manufacture facilitates cost low, can effectively utilize overhead waste heat, it is to increase the heat utilization rate of distillation tower, reduce enterprise cost.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of DPC reaction distillation column overhead heat recovery steam device, it is installed on the tower top of distillation tower, comprise thermal energy portion, described thermal energy portion is provided with thermal energy pipe, described thermal energy pipe has part to be wound on the upper end outer wall of described distillation tower, described thermal energy portion is connected with water inlet pipe and rising pipe, the level attitude of described water inlet pipe is lower than the level attitude of described rising pipe, described water inlet pipe and described rising pipe one end with described conduit are connected respectively, described water inlet pipe is connected with water tank, described rising pipe is connected with insulation can, described water inlet pipe is also provided with filtering and purifying.
In technique scheme, it may be preferred that described water tank is provided with water pipe, described water pipe is connected with water pump.
In technique scheme, it may be preferred that described insulation can is provided with aqueduct, described aqueduct is provided with valve.
Present configuration is simple and reliable, manufactures and facilitates cost low, it is possible to effectively utilizes the waste heat of overhead vapour, it is to increase the heat utilization rate of distillation tower, reduces enterprise cost.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: as shown in Figure 1, a kind of DPC reaction distillation column overhead heat recovery steam device, it is installed on the tower top of distillation tower 1, comprise thermal energy portion 2, described thermal energy portion 2 is provided with thermal energy pipe 23, described thermal energy pipe 23 has part to be wound on the upper end outer wall of described distillation tower 1, described thermal energy portion 2 is connected with water inlet pipe 21 and rising pipe 22, the level attitude of described water inlet pipe 21 is lower than the level attitude of described rising pipe 22, described water inlet pipe 21 and described rising pipe 22 one end with described conduit are connected respectively, described water inlet pipe 21 is connected with water tank 3, described rising pipe 22 is connected with insulation can 4, described water inlet pipe 21 is also provided with filtering and purifying 32.
Described water tank 3 is provided with water pipe 31, and described water pipe 31 is connected with water pump.
Described insulation can 4 is provided with aqueduct 41, and described aqueduct 41 is provided with valve.
This device is arranged like this, by the high temperature hot gas of overhead, by thermal energy portion 2, is converted into the heat energy of water, also heats up as hot water by water, then preserves being delivered to insulation can 4.
