Description

Technical Field

[0001] The utility model belongs to the technical field of carbon black production equipment, and specifically relates to an oil storage device for carbon black production. Background Art

[0002] Carbon black is a black powdery amorphous carbon, mainly used as a rubber reinforcing agent, in the manufacture of automobile tires, plastic additives, dyes, printing inks and other industries. The raw materials used in the production of carbon black are usually coal tar, anthracene oil, and ethylene tar. According to national standards, the water content of carbon black raw oil should be less than 0.5%, while the water content of externally purchased raw oil is generally 2-4%. Excessive water content will cause fluctuations in carbon black products and affect product quality. At present, most of the carbon black raw oil dehydration is carried out by heating the raw oil in the raw oil storage tank. The oil temperature needs to be controlled between 60℃ and 80℃, and the liquid level in the oil storage tank needs to be monitored. However, the existing operation is: 1. The raw oil is heated by installing a steam tube at the bottom of the raw oil tank, and the oil temperature is manually observed and the steam volume is controlled to control the temperature. This setting easily causes uneven heating of the raw oil in the oil tank, and insufficient heating leads to poor dehydration effect of the raw oil, thereby affecting the carbon black product indicators; 2. A float mechanical level gauge is used to judge the liquid level through observation through the manhole. This setting consumes a lot of manpower during operation and is prone to production accidents due to human errors. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an oil storage device for carbon black production, which overcomes the defects of the prior art, can automatically control the temperature and detect the liquid level, has good temperature control and dehydration effects, and thus ensures product quality.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0016] The utility model monitors the oil in the oil storage tank in real time through the liquid level radar component, the temperature sensor and the oil water content online monitoring sensor, so as to clearly know the oil liquid level height, the oil temperature and the water content of the oil. The oil in the tank can be evenly heated through the circulation pump and the pipeline, and the oil liquid level and the oil temperature can be automatically controlled through the automatic control system. The oil can be output only when the water content of the oil reaches the qualified standard, thus ensuring the safety of oil storage and the quality of subsequent products.

[0020] Embodiment 1

[0021] like Figure 1 As shown, the utility model is an oil storage device for carbon black production, comprising an oil storage tank body 2 provided with an interlayer 1, in which an electric heating coil 3 is provided; a feed port (not marked) is provided on one side of the top of the oil storage tank body 2, and a water vapor outlet (not marked) is provided on the other side; a liquid level radar assembly 4 is provided on the top of the inner cavity of the oil storage tank body 2, and a plurality of temperature sensors 5 and an oil product water content online monitoring sensor 6 are respectively provided on the side walls of the inner cavity; the bottom and the upper part of the side wall of the oil storage tank body 2 are respectively connected to a circulation pipeline (not marked) through a circulation pump 7; the electric heating coil 3, the temperature sensor 5, the oil product water content online monitoring sensor 6 and the circulation pump 7 are respectively electrically connected to an automatic control system 8, and the automatic control system 8 is electrically connected to an external power supply (not marked).

[0022] In actual application: when the crude oil is input into the oil storage tank body 2 from the oil tanker, when the liquid level radar component 4 monitors that a certain liquid level has been reached, the automatic control system 8 controls to stop inputting the crude oil. At this time, the crude oil is at room temperature, and the water content is much higher than the water content required for production, so it is necessary to heat up and remove water. The automatic control system 8 controls the electric heating coil 3 to start heating, and controls the circulation pump 7 to circulate so that the crude oil is evenly heated. When the oil temperature reaches 80 degrees, the heating is stopped and the circulation pump 7 is turned off to keep warm and remove water. When the oil temperature drops to 60 degrees, the heating and circulation program is automatically started to heat the crude oil. During this period, the oil water content online monitoring sensor 6 has been detecting the water content in the crude oil. When the water content is lower than 0.5%, the crude oil reaches the production standard and can be transported to the mixing tank for mixing, and then enters the production link in turn to complete the oil storage process.
