Abstract
The invention relates to an automatic drainage device for a tar storage tank; the automatic drainage device comprises online densimeters and drainage pipes; the online densimeters and the drainage pipes are fixed on the tar storage tank; the plurality of drainage pipes are uniformly arranged at the upper part of the tar storage tank along a height direction; the online densimeters are corresponding to the drainage pipes one by one, and the installation height of a bottom sensor of each of the online densimeters is aligned to the lower edge of the corresponding drainage pipe; electronic control valves are arranged on the drainage pipes and are electrically connected with the online densimeters by a PLC (programmable logic controller). Compared with the prior art, the automatic drainage device has the following beneficial effects: 1) the problem that a lot of light components are produced to occupy the tar storage space due to long standing time of tar is effectively solved, and the turnaround efficiency and the effective volume of the tar storage tank are improved; 2) the operation is flexible and convenient, and set values of the automatic densimeters can be changed as required to realize different drainage requirements; 3) the automatic control is realized by the PLC, so the operating environment of a worker is improved, the operation procedure is simplified, and the operation cost is reduced.
Description
Technical field
The present invention relates to coking industry technical field, particularly relate 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 invention 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 present invention 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 invention has the beneficial effects as follows:
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, the specific embodiment of the present invention is described further:
See Fig. 1, it is structural representation of the present invention, a kind of tar storage tank of the present invention 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 present invention, 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 present invention 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.
