Description
Technical field
The utility model belongs to chemical solvent field of refinement, is specifically related to a kind of refining plant of isopentane solvent.
Background technology
Isopentane is mainly derived from Petrochemical Enterprises, is mainly used in molecular sieve desorption at present, blowing agent and solvent are made in replacement fluorine Lyons.But the performance that can affect catalyst owing to containing some impurity in isopentane raw material even makes its inactivation.Therefore, needed to refine it before employing isopentane is as solvent preparation catalyst, process for purification is generally the mode adopting distillation, utilizes the difference of each component boiling point in liquid mixture and by Component seperation, reaches solvent-refined object.But in solvent-refined process, substandard product may be had and flow out.The appearance of substandard product not only causes the wasting of resources, also can reduce the purification efficiency of solvent.How to discharge the industrial waste gas produced in solvent refining processes is also a difficult problem simultaneously.
Summary of the invention
For the problems of the refining existence of existing isopentane solvent, the utility model provides a kind of refining plant of isopentane solvent, comprise the isopentane storage tank connected in turn, distillation still, distillate collecting tank and isopentane finished pot, be connected by return duct between described distillation still with distillate collecting tank; Adopt the refining plant of the isopentane solvent of this structure, defective product repeatedly can be distilled, reduce the waste rate of resource.
The utility model is by the following technical solutions: a kind of refining plant of isopentane solvent, comprises the isopentane storage tank connected in turn, distillation still, and distillate collecting tank and isopentane finished pot, be connected by return duct between described distillation still with distillate collecting tank; The top of described distillation still is destilling tower; Two 1# condensers and 2# condenser of connecting are connected with between described destilling tower with distillate collecting tank; Described 1# condenser and 2# condenser are two water condensation systems being connected to the series connection of circulating water inlet and circulating water outlet pipe; Described distillation still, 2# condenser and distillate collecting tank are all connected with raw material stove input pipe; Described isopentane storage tank, distillation still, distillate collecting tank, 1# condenser is all connected with nitrogen tube with 2# condenser; Described isopentane storage tank and distillation still, distillation still and 1# condenser, 1# condenser and 2# condenser, 2# condenser and distillate collecting tank, be connected by runner pipe between distillate collecting tank with isopentane finished pot; All bodys are provided with valve to control the flow direction of material.
Adopt the refining plant of the isopentane solvent of this structure, distill during isopentane is entered with heating system distillation still by runner pipe from isopentane storage tank, product of distillation condenses in a distillation column.After still-process, material just carries out water condensation by destilling tower by the condensed in two stages system that materail tube enters series connection and operates, and after water condensation Dynamic System, material is entered in distillate collecting tank by runner pipe and collects.Grade product stores directly entering isopentane finished pot, and defective product will enter destilling tower by return duct and re-start distillation process.If repeatedly product of distillation is still defective, then carry out burning process by raw material stove input pipe.In distillation and condensation process process, also producing some waste gas simultaneously carrying out burning process, for raw material stove provides the energy by directly entering raw material stove input pipe.Whole subtractive process carries out operating under whole process leads to the condition of nitrogen, realizes, and carry out convey materials by nitrogen in the utility model by connecting nitrogen tube on each device.
In sum, adopt the refining plant of the isopentane solvent of this structure, whole process is directly convenient, reduces operating procedure, improves purification efficiency.Waste gas and defective product can be drained into raw material stove by raw material stove input pipe simultaneously and carry out burning process, improve the utilization rate of the energy, reach the object of environmental protection.1# condenser is connected with for circulating water outlet pipe with circulating water inlet respectively with the two-stage water-cooling system in 2# condenser, has accomplished circulation water reuse, has saved water resource, reduced production cost to a certain extent.Return duct be arranged so that defective product can repeatedly distill, saved industrial cost, reduced resource waste rate.
