Description
Technical field
The utility model relates to coking industry technical field, particularly relates to a kind of tar storage tank automatic draining device that can realize tar storage tank top light component automatic-discharging.
Background technology
China, as a coal big country and big steel country, there is the coal chemical enterprise of One's name is legion in China, and tar is a kind of important side production in coal chemical enterprise.In common process, tar needs to be stored in tar storage tank a period of time, makes tar and light component standing separation.But along with the lengthening of time of repose, have a certain amount of light component and separate out, constantly occupy the storage space of tar.So in traditional technological process, usually can offer several leakage fluid drams on tar storage tank top, by manual operation, open leakage fluid dram valve one by one, find the liquid layer of light component.This traditional method is not only time-consuming but also require great effort, and needs to discharge a certain amount of liquid determination layer height by leakage fluid dram, cannot judge exactly and discharge top light component in time, and tapping process continually also impacts the standing separation effect of tar.
Summary of the invention
The utility model provides a kind of tar storage tank automatic draining device, effective solution produces with tar time of repose length the problem that a large amount of output of light component occupies tar storage space, by the timely automatic drain of automatic control realization, improve the operating environment of workman, simplify operating process, reduce running cost.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of tar storage tank automatic draining device, comprise and be fixed on on-line densimeter and drain pipe on tar storage tank, described drain pipe is multiple, tar storage tank top is evenly arranged on along short transverse, on-line densimeter and drain pipe one_to_one corresponding, and the bottom sensor rational height of each on-line densimeter aligns with the lower edge of corresponding drain pipe; Drain pipe establishes electric control valve, is electrically connected with on-line densimeter by PLC.
The material of described on-line densimeter sounding rod is 316 corrosion-resistant steels or Hastelloy.
Compared with prior art, the beneficial effects of the utility model are:
1) efficiently solve because tar time of repose is long and produce the problem that a large amount of output of light component occupies tar storage space, improving all transfer efficients of tar storage tank and effective volume;
2) flexible and convenient operation, can change the setting value of automatic density instrument as required, realizes different discharge opeing demands;
3) realize automatically controlling by PLC, improve the operating environment of workman, simplify operating process, reduce running cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, a kind of tar storage tank of the utility model automatic draining device, comprise and be fixed on on-line densimeter 3 ~ 6 and drain pipe 7 ~ 10 on tar storage tank 1, described drain pipe is multiple, evenly be arranged on tar storage tank 1 top along short transverse, on-line densimeter 3 ~ 6 and drain pipe 7 ~ 10 one_to_one corresponding, and the bottom sensor rational height of each on-line densimeter 3/4/5/6 aligns with the lower edge of corresponding drain pipe 7/8/910; Drain pipe 7 ~ 10 is established electric control valve 11 ~ 14, be electrically connected with on-line densimeter 3 ~ 6 by PLC.
The material of described on-line densimeter 3 ~ 6 sounding rod is 316 corrosion-resistant steels or Hastelloy.
As shown in Figure 1, being a kind of concrete form of the utility model, depositing tar mixed liquor in tar storage tank 1, through leaving standstill for a long time, isolate bottoms tar 15 and top light component 2, but routine techniques cannot judge when the released state of liquid reaches requirement and concrete point liquid layer position.Device shown in figure is provided with 4 on-line densimeters 3 ~ 6 on tar storage tank 1 top, and its sounding rod length differs, and its end sensor is evenly arranged in the height direction, is respectively used to the fluid density of monitoring different liquid level.On the sidewall of tar storage tank 1, corresponding on-line densimeter 3 ~ 6 sensor height position is provided with 4 drain pipes 7 ~ 10 respectively, drain pipe 7 ~ 10 is respectively equipped with electric control valve 11 ~ 14.
A kind of tar storage tank of the utility model automatic draining device principle of work be: the density of automatic monitoring tar storage tank 1 upper liquid of on-line densimeter 3 ~ 6, and by transmitter, digitized observed reading is sent to PLC, setting value is pre-entered in PLC, when observed reading reaches setting value, PLC sends control signals to electric control valve 11 ~ 14, and electric control valve 11 ~ 14 is automatically opened and discharged tar storage tank 1 top light component 2.
The survey sensor of on-line densimeter 3 ~ 6 is arranged on differing heights, when the fluid density of a certain height reaches setting value, the electric control valve 11 ~ 14 that PLC controls respective heights is opened, by drain pipe 7 ~ 10 discharge opeing of correspondence, reach accurately, discharge in time the object of tar storage tank top light component.When density value as on-line densimeter 1 monitoring reaches setting value, the electric control valve 1 on drain pipe 1 opens discharge opeing, and when the density value that on-line densimeter 24 is monitored reaches setting value, the electric control valve 2 12 on drain pipe 28 opens discharge opeing, by that analogy.Setting quantity and the height of drain pipe and on-line densimeter need to determine according to scene.
