Problems solved by technology

[0002] The scum inventory in the workshop remains high, and there is a huge pressure on the environmental protection operation facilities. The daily refining capacity of the coking workshop is 18 tons, which can no longer effectively alleviate the current problem of scum inventory in the power workshop and the pressure on environmental protection.
Coking scum back-smelting flowmeter limit, appearing in the later stage of back-smelting, obvious pipeline vibration, and potential safety hazards; therefore, in order to solve the above problems, it is particularly important to design a method of using coke towers for back-smelting scum

Embodiment Construction

[0012] The invention provides a method for refining scum by using a coke tower:

[0013] S1: Start the scum pump, so that the scum is transported into the coke tower along the 10-meter scum valve;

[0014] S2: 20 minutes after the scum enters the coke tower, start the water pump to supply water to the coke tower, and after confirming that the cold coke water enters the coke tower, close the steam supply valve;

[0015] S3: By raising the temperature of the coke tower, the temperature is raised to 450°C-500°C to refine the scum.

[0016] In the above step S1, the post personnel observe the on-site pressure gauge of the 10-meter scum valve water supply line, open the water supply valve after the pressure rises, and keep the steam supply at 2.5-3t / h.

[0017] In the above step S2, the water supply rate is maintained at about 25t / h, and the scum refining rate is maintained at 45t / h, and the scum pump is stopped after the scum refining for about 15 minutes, and the scum valve is c...

Abstract

The invention relates to a method for remixing scum by applying a coking tower. The method comprises the following steps: S1: starting up a scum pump to enable scum to be conveyed into the coking tower along a dekameter scum valve; S2: starting up a water pump to feed water to the coking tower 20 minutes after the scum enters the coking tower, confirming that coke cooling water enters the coking tower, and then, shutting down a steam supplying valve; and S3: heating up the coking tower, and remixing the scum until the temperature rises to 450 DEG C to 500 DEG C. By adopting the method, the daily remixing amount can be greatly increased, the scum warehousing of companies can be effectively relieved, the environmental protection pressure is powerfully lowered, and an expected effect is achieved.

Description

technical field [0001] The invention relates to a method for refining scum, in particular to a method for refining scum by using a coke tower. Background technique [0002] The scum inventory in the workshop remains high, and there is huge pressure on the environmental protection operation facilities. The 18 tons of refining capacity per day in the coking workshop can no longer effectively alleviate the current scum inventory problem in the power workshop and the pressure on environmental protection. Coking scum back refining flow meter limit, appear in the late refining, obvious pipeline vibration, there are safety hazards; so in order to solve the above problems, it is particularly important to design a method of using coke tower for scum refining. Contents of the invention [0003] The present invention will immediately stop the scum refining after the coke tower re-smelting temperature drops to 290°C, so as to avoid the situation that the scum cannot completely react i...
