Description
Technical field
The present invention relates to oil-refining chemical industry Large Oil Tank cleaning technique fields, and in particular to one kind is exempted to accompany oil washer
The method of the clear tank of tool.
Background technology
With the promotion of oil-refining chemical enterprise production capacity, crude oil storage capacity greatly increases, and petroleum tank overhauls the need to mechanical tank cleaning
Ask growing.Currently, cleaning crude oil storage tank needs the light-weight fuel oil using 2-4 times of tank bottom oil sludge reserve as accompanying early period
Washing oil, these light-weight fuel oils are mostly product oil, are mixed just into sump oil with heavy dirty oil, tank bottom sludge after treatment.One
The prodigious waste of lightweight finished fuels oil is caused, a large amount of sump oils is accordingly generated, occupies huge stocks；Two increase device sump oil
Freshening rate, more important is some crude oil tank farms not to have this kind of light oil, more not the channel of dirty oil recycling, this just gives oil tank clear
It washes and increases very burden；Three carry out the processing production capacity that freshening sump oil occupies many valuable devices again, cause vicious circle, economical
Cost is also larger.Therefore, the large-scale oil depot for not light-weight fuel oil or do not have freshening sump oil ability enterprise, can only hope and
Step, has seriously affected the business development of mechanical tank cleaning, it would be highly desirable to develop a set of stronger method of mechanical tank cleaning Technological adaptability.
Invention content
The purpose of the invention is to overcome the prior art to exist to accompany washing oil cleaning to lead to follow-up complicated processes and accompany washing oil
A large amount of wastes the problems such as, a kind of method for exempting to accompany washing oil mechanical tank cleaning is provided.
To achieve the goals above, one aspect of the present invention provides a kind of method for exempting to accompany washing oil mechanical tank cleaning, including following
Step：
(1) heating tank base oil makes it have certain mobility, and then vacuum suction out and on force feed to can body is arranged
Mechanical injection equipment, action of forced stirring mixing；
(2) continue heating tank base oil, make deep fat that there is 360 degree of flows without dead angle Hybrid Heating in tank；
(3) each point temperature and liquid level in tank are checked, each point temperature, liquid level change curve are drawn out, is machine
Tool spraying equipment provides data and supports；
(4) when each point temperature and liquid level tend to be steady, start, to oil is sent outside, to be carried out at the same time hot-oil circulation heat preservation；
(5) after sending oil, the aqueous-base cleaning hot water circuit of largest loop flow is established, heavy oil is periodically skimmed into recycling,
When no heavy oil skims, terminate aqueous-base cleaning.
Compared with prior art, the invention has the advantages that：
1) mechanical tank cleaning technique is eliminated to accompanying the source of washing oil and the misgivings in place to go；
2) consumption of cleaning supplies is reduced；
3) adaptability of mechanical tank cleaning is improved.
Specific implementation mode
