Description
Technical field
The present invention relates to nitrocotton production field, a kind of horizontal pushing centrifuge oil temperature for nitrocotton cools down
Device and improved method thereof.
Background technology
Along with the development of science and technology, the range of application of nitrocotton is no longer confined on war products, but is embodied in daily life
The every aspect lived, such as Automobile paint, solid alcohol, coating, ink and electronic product binding agent etc..Actual production process
In, need the cotton-wool after nitrification to carry out the cotton separation of acid, it is common that being completed by centrifuge, centrifuge long-term work will result in
Hydraulic oil temperature rises, and the viscous stickiness causing hydraulic oil is not strong, and impact uses.
Tradition, for reducing centrifuge hydraulic fluid temperature, is outside equipped with shell and tube heat transmitter, shell and tube heat transmitter at centrifuge
Being connected to tap water by pipeline one end, the other end is connected to cesspool, reduces hydraulic oil by the temperature difference of hydraulic oil and water
Temperature.But, owing to tap water is without process, before carrying out heat exchange, temperature is ambient temperature, when summer temp is too high, from
Water is too small with the hydraulic oil temperature difference, and rate of heat exchange is low；Winter, north temperature was on the low side, and generally below 0 DEG C, tap water can at 0 DEG C
Freeze, be thus inconvenient to carry out heat exchange；And tap water is inconvenient to be circulated use, so the loss of tap water is big, make
Become the waste of a large amount of tap water, add operating cost.
Summary of the invention
The present invention solves that the problem that heat exchanger effectiveness is low provides a kind of horizontal pushing centrifuge oil temperature for nitrocotton
Chiller and improved method thereof.
The technical solution adopted in the present invention is: for the horizontal pushing centrifuge oil temperature chiller of nitrocotton, including
Tubular heat exchanger, described tubular heat exchanger is provided with the first entrance and the first outlet of outflow that hydraulic oil flows into, and heat is handed over
Change the second entrance and the second outlet of outflow that medium flows into, also include cooling down the freezing unit of heat exchange medium and power being provided
Circulating pump, be sequentially connected in series freezing unit and circulating pump formation loop by pipeline between described second outlet and the second entrance,
Increase the temperature difference between hydraulic oil and heat exchange medium solution, improve heat exchanger effectiveness.
For avoiding solution not freeze below 0 DEG C, the heat exchange medium in described pipeline group is that freezing point is less than 0 DEG C molten
Liquid, the most preferably NaNO3Solution.
For avoiding NaNO3Solution corrosion tubular heat exchanger and pipeline, described tubular heat exchanger and pipeline are by rustless steel
Material is made.
Described freezing unit is to NaNO3The limit that solution carries out cooling down is-8 DEG C, for reaching preferable cooling effect, by cold
But temperature controls at-8 DEG C to-5 DEG C.
The invention has the beneficial effects as follows: carry out before heat exchange first by NaNO3Solution carries out being cooled to-8 DEG C to-5 DEG C again
Carry out heat exchange, greatly improve NaNO3Solution and the temperature difference of hydraulic oil, improve heat exchanger effectiveness；After heat exchange
NaNO3Solution reclaims, and re-starts cooling, the method reusable edible, reduces cost.

Fig. 1 is present configuration schematic diagram.
Figure is labeled as: 1, tubular heat exchanger；2, the first entrance；3, the first outlet；4, the second entrance；5, second goes out
Mouthful；6, circulating pump；7, pipeline；8, freezing unit.
Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention is the horizontal pushing centrifuge oil temperature chiller for nitrocotton and improved method thereof,
Hydraulic oil enters tubular heat exchanger 1 by the first entrance 2, by the first outlet 3 outflow tubular heat exchanger 1, and shell and tube
NaNO after cooling down in heat exchanger 13Solution carries out heat exchange, realizes the cooling of hydraulic oil with this, keeps hydraulic fluid temperature to control
At 45 DEG C 55 DEG C, the NaNO after heat exchange3Solution enters freezing unit 8 by pipeline 7 and cools down, and flows from freezing unit 8
The NaNO gone out3Solution is flowed into tubular heat exchanger by circulating pump and carries out heat exchange, circulates with this.
