Abstract
The utility model provides a spent lubrication oil dehydrating device relating to the technical field of spent lubrication oil regeneration treatment devices. The spent lubrication oil dehydrating device comprises a centrifugal pump, a primary dehydration tower and a single heating device, and further comprises a secondary dehydration tower and a double heating device, wherein an oil material outlet of the primary dewatering tower is connected with an oil material inlet of the single heating device through the centrifugal pump, an oil material outlet of the single heating device is connected with an oil material inlet of the secondary dehydration tower, an oil material outlet of the secondary dehydration tower is connected with an oil material inlet of the double heating device through the centrifugal pump, and an oil material outlet of the double heating device is connected with an oil material inlet of the next procedure. The primary dehydration tower is a plate tower, and the secondary dehydration tower is a plate tower. According to the spent lubrication oil dehydrating device, the adaptability of the spent lubrication oil dehydrating device to raw materials is greatly improved, the treatment capacity of the spent lubrication oil dehydrating device is improved, and the pretreatment requirement of the raw materials and the subsequent distillation pressure are reduced.
Description
Technical field
The utility model relates to a kind of waste lubricant oil regeneration treatment unit technical field, is specifically related to a kind of waste lubricating oil dewatering unit.
Background technology
China is the consumption big country of lubricating oil, and As time goes on lubricating oil in use can lose the anti-friction wear-resistant ability gradually, in case become waste lubricating oil in the time of can not satisfying working condition requirement with regard to having lost using value.Along with the day by day exhaustion of petroleum resources and the enhancing of human environmental consciousness, waste internal-combustion engine oil recovery, purification and recycle also have been subject to the great attention of countries in the world, have researched and developed various process for regeneration of waste lubricating oil and device thereof.Usually, waste lubricant oil regeneration is divided into four large steps: the first step is the insolubless such as bituminous matter that remove in the waste oil; Second step is moisture and the light oil constituents that removes in the waste oil; The 3rd step was the dissolvable oxides that removes in the waste oil; The 4th step was that lubricating base oils is made with extra care decolouring.Wherein the moisture and the light oil constituents that remove in the waste oil of second step adopts corresponding dewatering unit to carry out, yet a cover dewatering unit often only is set in the existing waste lubricant oil regeneration treatment unit, when waste oil moisture large, not only increased the pretreated requirement of raw material but also bring pressure to follow-up distillation when treatment capacity is many, the device processing power reduces.
The utility model content
The utility model for overcome existing waste lubricating oil dewatering unit large in the raw material water content, when treatment capacity is many, the processed ability descends, not only increased the pretreated requirement of raw material but also brought the defective of pressure to follow-up distillation, a kind of waste lubricating oil dewatering unit was provided.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: a kind of waste lubricating oil dewatering unit, comprise impeller pump, one-level dehydration tower and a heating installation, also comprise secondary dehydration tower and second heating device, the oil plant outlet of described one-level dehydration tower is connected with the oil plant import of a heating installation through impeller pump, the oil plant outlet of a heating installation is connected with the oil plant import of secondary dehydration tower, the oil plant outlet of secondary dehydration tower is connected with the oil plant import of second heating device through impeller pump, and the oil plant outlet of second heating device is connected with the oil plant import of subsequent processing.
Described one-level dehydration tower is tray column.
Described secondary dehydration tower is tray column.
Adopt said structure, the utility model enters the one-level dehydration tower, moisture and volatile matter condensation separation after cat head is gone out after can making waste lubricating oil through a heating installation heating.Oil after the dehydration is extracted out at the bottom of tower.Then enter the secondary dehydration tower through the second heating device heating, same cat head is isolated moisture and volatile matter, extracts out at the bottom of tower through the oil of dehydration.Thereby device is increased greatly to the adaptability of raw material, improved the processing power of device.The pre-treatment that has reduced raw material requires and follow-up distillation pressure.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model embodiment.
Embodiment
The below is further described take specific embodiment as the utility model, referring to Fig. 1: a kind of waste lubricating oil dewatering unit, comprise impeller pump, one-level dehydration tower 2 and a heating installation 3, also comprise secondary dehydration tower 4 and second heating device 5, the oil plant outlet of described one-level dehydration tower 2 is connected with the oil plant import of a heating installation 3 through impeller pump 1, the oil plant outlet of a heating installation 3 is connected with the oil plant import of secondary dehydration tower 4, the oil plant outlet of secondary dehydration tower 4 is connected with the oil plant import of second heating device 5 through impeller pump 6, and the oil plant outlet of second heating device 5 is connected with the oil plant import of subsequent processing.
Described one-level dehydration tower 2 is tray column.
Described secondary dehydration tower 4 is tray column.
It should be noted that at last: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
