Description

Technical Field

[0001] The utility model relates to the field of needle coke treatment, in particular to a needle coke pretreatment device. Background Technique

[0002] The commonly used methods for removing coke from needle coke at home and abroad are mainly the method of hydraulic coke removal and open-air stacking of green coke. That is, when removing coke from the coking tower of needle coke, the top cover and bottom cover of the coking tower are opened, the coke cutter enters from the top cover, and the cut green needle coke and cutting water enter the open-air coke pond from the bottom cover. The green coke in the coke pond is dehydrated by open-air static settlement and then fed by a bridge (or gantry) crane, and sent to the downstream device by a belt conveyor. This coke removal method has a simple process and realizes the processes of green coke storage, dehydration and transportation through the combination of an open-air coke pond + a bridge (or gantry) crane.

[0003] However, since there is no gas collection device on the top cover and bottom cover during coke removal from the coking tower, the green coke and cutting water enter the open-air coke pond, and the organic gas diffuses randomly, causing environmental pollution. The green needle coke stacked in the open air will be polluted by sand and dust, resulting in an increase in the impurity content of the product, a decrease in the conductivity of the product, and an increase in the resistivity. Therefore, we propose a needle coke pretreatment device to solve the above problems. Content of the Utility Model

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

These organic gases can be collected in a timely manner to prevent them from diffusing randomly into the surrounding environment, thereby reducing pollution to the atmosphere, soil, and water bodies and protecting the ecological environment. The motor can drive the crushing rod to crush the needle coke. After crushing, the needle coke particles become smaller, and moisture is more likely to seep out from the interior of the particles during the subsequent dehydration process, thus improving the dehydration efficiency. The flushing water pipe injects water into the dehydration tank for cleaning and dehydration. After dehydration, the needle coke realizes solid-liquid separation under the action of the Johnson screen, greatly improving the separation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
