Description
Technical field
The present invention relates to coking industry technical field, more particularly to one kind can realize that tar storage tank top light component is automatic
The tar storage tank automatic draining device of discharge.
Background technology
China is as a coal big country and big steel country, in China there is large number of coal chemical enterprise,
And tar is a kind of important byproduct in coal chemical enterprise.In common process, tar needs to be stored in one in tar storage tank
The section time, make tar and light component standing separation.But with the lengthening of time of repose, have a certain amount of light component and separate out, no
The disconnected storage space for occupying tar.So in traditional technological process, it will usually open up several rows on tar storage tank top
Liquid mouth, by manual operation, leakage fluid dram valve is opened one by one, finds the liquid layer of light component.This traditional method it is not only time-consuming but also
Arduously, it is necessary to which discharging a certain amount of liquid by leakage fluid dram determines layer height, it can not exactly judge and discharge top in time
Light component, and continually tapping process also impacts to the standing separation effect of tar.
The content of the invention
The invention provides a kind of tar storage tank automatic draining device, effectively solves long with tar time of repose and produces
The problem of a large amount of outputs of light component occupy tar storage space, timely automated discharge opeing is realized by automatically controlling, improves worker
Operating environment, simplify operating process, reduce running cost.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of tar storage tank automatic draining device, including it is fixed on on-line densimeter and discharging tube on tar storage tank, institute
Discharging tube to be stated to be multiple, tar storage tank top is uniformly arranged on along short transverse, on-line densimeter corresponds with discharging tube, and
The bottom sensor of each on-line densimeter sets height to be alignd with the lower edge of corresponding discharging tube；Electric control valve is set on discharging tube,
Electrically connected by PLC with on-line densimeter.
The material of the on-line densimeter measurement bar is 316 stainless steels or Hastelloy.
Compared with prior art, the beneficial effects of the invention are as follows：
1) efficiently solve and produce a large amount of outputs of light component because tar time of repose is long and occupy asking for tar storage space
Topic, improve tar storage tank week transfer efficient and dischargeable capacity；
2) flexible and convenient operation, the setting value of automatic density instrument can be changed as needed, realizes different discharge opeing demands；
3) realized and automatically controlled by PLC, improved the operating environment of worker, simplify operating process, reduce operation
Cost.

In figure：1. the on-line densimeter three of one 4. on-line densimeter of tar storage tank 2. light component, 3. on-line densimeter 2 5.
6. the electric control valve 1 of 3 10. discharging tube of on-line densimeter 4 7. discharging tube, one 8. discharging tube, 2 9. discharging tube 4 11.
The tar of 2 13. electric control valve of electric control valve, 3 14. electric control valve 4 15.
Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings：
See Fig. 1, be the structural representation of the present invention, a kind of tar storage tank automatic draining device of the present invention, including fixation
On-line densimeter 3~6 and discharging tube 7~10 on tar storage tank 1, the discharging tube are multiple, are uniformly arranged along short transverse
On the top of tar storage tank 1, on-line densimeter 3~6 corresponds with discharging tube 7~10, and each on-line densimeter 3/4/5/6
Bottom sensor sets height to be alignd with the lower edge of corresponding discharging tube 7/8/910；Set on discharging tube 7~10 electric control valve 11~
14, electrically connected by PLC with on-line densimeter 3~6.
The material of the measurement bar of on-line densimeter 3~6 is 316 stainless steels or Hastelloy.
As shown in figure 1, being a kind of concrete form of the present invention, tar mixed liquor is deposited in tar storage tank 1, by for a long time
Stand, isolate bottoms tar 15 and top light component 2, but routine techniques can not judge when the released state of liquid reaches
It is required that and specific liquid separation layer position.Device shown in figure is provided with 4 on-line densimeters 3~6 on the top of tar storage tank 1, its
Measurement pole length differs, and its end sensor is uniformly arranged in the height direction, is respectively used to monitor different liquid levels
Fluid density.In the side wall of tar storage tank 1, the corresponding sensor height position of on-line densimeter 3~6 is respectively provided with 4 rows
Liquid pipe 7~10, electric control valve 11~14 is respectively equipped with discharging tube 7~10.
A kind of tar storage tank of the present invention is with the operation principle of automatic draining device：On-line densimeter 3~6 monitors automatically
The density of the upper liquid of tar storage tank 1, and digitized measured value is sent to by PLC, PLC by transmitter
In pre-enter setting value, when measured value reaches setting value, PLC sends control signals to electric control valve 11~14, electrically-controlled valve
Door 11~14 automatically turns on the top light component 2 of discharge tar storage tank 1.
The measurement sensor of on-line densimeter 3~6 is arranged on different height, when the fluid density of a certain height reaches setting
During value, the electric control valve 11~14 of PLC control respective heights is opened, by the corresponding discharge opeing of discharging tube 7~10, reach it is accurate,
The purpose of tar storage tank top light component is discharged in time.When density value such as the monitoring of on-line densimeter 1 reaches setting value, row
Electric control valve 1 in liquid pipe 1 opens discharge opeing, when the density value that on-line densimeter 24 monitors reaches setting value, discharging tube
Electric control valve 2 12 on 28 opens discharge opeing, by that analogy.The setting quantity of discharging tube and on-line densimeter and height are according to existing
It needs to be determined that.
