Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, specifically referring to a liquid coal tar pitch cooling and granulation device. Background Technology

[0002] In the oil refining and chemical industry, coal tar produced through the dry distillation of petroleum feedstocks, semi-coke ovens, and coke ovens is heated and vaporized in the refining equipment's heating furnace. The resulting compounds, before solidification, are extracted and precipitated into high-temperature liquid coal tar pitch (i.e., residual oil), which is toxic and liquid. Reuse requires transportation by specialized hazardous chemical tanker trucks. During transportation, heating is necessary to prevent the high-temperature liquid coal tar pitch from solidifying, posing a risk of fire and explosion, which would cause severe environmental pollution in the event of an accident. Furthermore, the high-temperature liquid coal tar pitch produced during refining requires temporary storage in tanks to prevent solidification, which could malfunction production equipment and disrupt production, leading to numerous disadvantages. To facilitate transportation, liquid coal tar pitch is granulated.

[0003] Existing liquid coal tar pitch cooling granulation devices mostly use single drum cooling or spray cooling methods, which have low cooling efficiency and the particles are prone to agglomeration and adhesion, making it difficult to meet the production requirements of high efficiency, environmental protection and high quality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model proposes a liquid coal tar cooling granulation device, which effectively solves the problems that liquid coal tar cooling granulation devices mostly adopt single drum cooling or spray cooling methods, resulting in low cooling efficiency, easy agglomeration and adhesion of particles, and difficulty in meeting the production requirements of high efficiency, environmental protection and high quality.

[0005] The technical solution adopted by this utility model is as follows: The liquid coal tar pitch cooling granulation device proposed by this utility model includes a base, and a granulation cooling structure is provided on the base. The granulation cooling structure includes a cooling unit and a granulation unit. The cooling unit is provided on the base, the granulation unit is provided on the base, and a separation unit is provided on the base.

[0006] Preferably, the cooling unit includes a support base fixedly disposed on both sides of the base, a cooling tower fixedly disposed on the support base, a water spray pipe fixedly disposed at the bottom of the cooling tower, a water pump fixedly disposed on the bottom side of the support base, a water pump having a drain outlet connected to one end of a delivery pipe and the other end of the delivery pipe connected to the water spray pipe, and a water inlet connected to a pumping pipe.

[0007] To achieve better results, the granulation unit includes a fixed base in the middle of the base, a motor fixed above the fixed base, a centrifuge cylinder fixed on the output shaft of the motor, and a heater installed at the bottom of the centrifuge cylinder.

[0008] To achieve separation more quickly, the separation unit includes an inclined groove inside the base, and a filter screen is provided on the lower side of the inclined groove.

[0009] Furthermore, the cooling tower is configured in a funnel shape, the bottom of the water spray pipe is provided with a ring of water holes, the bottom of the centrifuge tube is provided with several sets of separation holes, and the centrifuge tube is located at the center of the cooling tower.

[0010] To achieve efficient cooling, the water jets from the spray pipes form a water curtain as they slide downwards along the inner wall of the cooling tower.

[0011] The beneficial effects of this utility model using the above structure are as follows: The liquid coal tar pitch cooling granulation device proposed in this solution uses a granulation unit for granulation and a water flow sprayed from a water spray pipe on the cooling unit for cooling, realizing the integration of granulation and cooling, achieving uniform granulation, and facilitating transportation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figure 2 and Figure 3 As shown, the present invention proposes a liquid coal tar pitch cooling granulation device, which includes a base 1, a granulation cooling structure 2 on the base 1, a cooling unit 3 and a granulation unit 4, the cooling unit 3 and the granulation unit 4 being disposed on the base 1, and a separation unit 5 being disposed on the base 1.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cooling unit 3 includes a support base 6 fixedly mounted on both sides of the base 1. A cooling tower 7 is fixedly mounted on the support base 6. The cooling tower 7 is funnel-shaped. A water spray pipe 8 is fixedly mounted at the bottom of the cooling tower 7. A series of water holes are arranged at the bottom of the water spray pipe 8. When the water sprayed from the water spray pipe 8 slides down the inner wall of the cooling tower 7, it forms a water curtain. A water pump 9 is fixedly mounted on the bottom side of the support base 6. One end of the water pump 9 is connected to the drain port of the water pump 9 and the other end of the water pump 10 is connected to the water spray pipe 8. A water pumping pipe 11 is connected to the inlet of the water pump 10.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the granulation unit 4 includes a fixed base 12 fixedly disposed in the middle of the base 1, a motor 13 fixedly disposed above the fixed base 12, a centrifuge cylinder 14 fixedly disposed on the output shaft of the motor 13, a number of separation holes are provided at the bottom of the centrifuge cylinder 14, the centrifuge cylinder 14 is disposed at the center of the cooling tower 7, and a heater 15 is installed at the bottom of the centrifuge cylinder 14.

[0022] like Figure 1 and Figure 3 As shown, the separation unit 5 includes an inclined groove 16 opened inside the base 1 above, and a filter screen 17 is provided on the lower side of the inclined groove 16.

[0023] In practical use, first connect the water pump 11 to the water source, then control the water pump 9 to draw cold water through the water pump 11 and pump it into the spray pipe 8 through the delivery pipe 10. At this time, the water flow is sprayed from the spray hole on the lower side of the spray pipe 8 towards the inner wall of the cooling tower 7, thus forming a water curtain. Then control the motor 13 to drive the centrifuge drum 14 to rotate at high speed. At the same time, use the heater 15 to heat it, and then add the molten asphalt from the top into the centrifuge drum 14. At this time, the asphalt is dispersed outward under the centrifugal action of the centrifuge drum 14. The asphalt is then thrown onto the inner wall of the cooling tower 7. At this time, the cold water flow quickly cools and solidifies the asphalt particles, and they flow into the inclined trough 16 with the water flow. After being filtered by the filter screen 17, the asphalt particles are collected for easy transportation.
