Description

Technical Field

[0001] This utility model relates to the field of port oily wastewater treatment technology, specifically to a port grease trap with heating function and a port oil transportation system using the same. Background Technology

[0002] In the field of port oily wastewater treatment technology, oily wastewater from ships or ports is transferred to port grease traps via dedicated receiving facilities. Oil-water separation is achieved through demulsification, flocculation, and sedimentation technology (typically, the collected oily wastewater is stored in the grease trap, where demulsification, flocculation, and sedimentation occur). The separated waste oil is then transported away by tanker trucks. A large port in South China can separate over 100 tons of oily wastewater daily in winter. Assuming the water content of the oily wastewater is around 30%, approximately 60-65 tons of waste oil are processed daily, and the water content of the waste oil after flocculation and sedimentation separation must not exceed 5%. In existing technologies, even with demulsifiers, oily wastewater often fails to separate due to the low temperature (around 10°C), easily leading to production stoppages and economic losses. Given limited port power supply, limited port space, and the need for convenient collection and transportation of waste oil, how to avoid the problem of low port oily wastewater treatment efficiency in winter has become a key research direction for those skilled in the art. Utility Model Content

[0019] The second oil loading arm is used to transport the oil that has undergone oil-water separation treatment, which flows through the first and second oil loading arms, to the oil tanker located next to the main body of the oil separator via the oil pump in the loading arm.

[0023] Furthermore, the oil loading arm installation platform is also equipped with a staircase, which is used to facilitate personnel to climb to the top of the oil loading arm installation platform and observe the interior of the oil separator body from below.

[0038] Example 1

[0039] like Figure 1 , Figure 3 , Figure 4 As shown:

[0040] This embodiment proposes a port grease trap with heating function, including:

[0041] The main body 1 of the oil separator is installed in the port for storing and treating oily wastewater;

[0042] A tubular heat exchanger 2 is installed inside the main body 1 of the oil separator; the tubular heat exchanger 2 contains heat transfer oil, and the structure of the tubular heat exchanger 2 is in the form of a pipe network, thereby increasing the contact area between the tubular heat exchanger and the oily wastewater in the oil separator.

[0043] The electric heating heat transfer oil tank 3 is used to heat the heat transfer oil flowing from the tubular heat transfer oil heat exchanger 2 into the electric heating heat transfer oil tank 3; the second heat transfer oil outlet 32 ​​of the electric heating heat transfer oil tank 3 is connected to the first heat transfer oil inlet 21 of the tubular heat transfer oil heat exchanger 2.

[0044] The hot oil pump 4 is used to circulate and exchange the heat transfer oil between the tubular heat transfer oil heat exchanger 2 and the electrically heated heat transfer oil tank 3; the third heat transfer oil inlet 41 and the third heat transfer oil outlet 42 of the hot oil pump 4 are respectively connected to the first heat transfer oil outlet 22 of the tubular heat transfer oil heat exchanger 2 and the second heat transfer oil inlet 31 of the electrically heated heat transfer oil tank 3.

[0045] Ideally, the main body 1 of the oil separator is covered with an insulation layer; this avoids significant heat loss from the main body 1 of the oil separator.

[0046] Ideally, the tubular heat exchanger 2 includes at least two layers of sequentially connected pipe networks 23 at different heights, thereby further increasing the contact area between the tubular heat exchanger and the oily wastewater in the oil separator.

[0047] Ideally, the pipe network 23 is a pipe coil structure in the shape of a snake, formed by connecting multiple U-shaped pipes in sequence.

[0048] Specifically, using the 300m³ grease trap 1 of the port, two sets of tubular heat exchangers 2 can be installed to heat the sludge and oil in the grease trap. An external 300kW electric heating device is installed to heat the sludge and oil in the tank. A hot oil pump 4 is used for the circulating heating process. The existing sludge scraper of the original grease trap 1 can also be used as a stirring and heat exchange mechanism to build a set of oily wastewater demulsification, flocculation and sedimentation device with heating and stirring device. Under the condition that the port only has 150-300kW of available power load and cannot use open flame heating, the sludge and oil can be directly heated by the tubular heat exchangers 2.

[0049] Specifically, through an experiment using a port grease trap with heating function in this embodiment, the heating time required to raise 200m³ of oily wastewater in the grease trap to a set temperature under the condition that the main body 1 of the grease trap is covered with an insulation layer can be calculated. The set heating termination temperatures are 40℃, 35℃, and 30℃. Referring to the average temperature in summer, the time required to heat to 30℃ is taken as the heating working time. The calculation results are shown in Table 1 below:

[0050]

[0052] This embodiment describes a port grease trap with heating function for treating oily wastewater. In winter, it uses a power supply of 150 kW during the day and 300 kW at night. The oily wastewater is directly heated by an electrically heated heat transfer oil tank 3. It processes 200 m³ of oily wastewater per day and produces eight truckloads of oil every two days.

[0065] Further optimized, the oil loading arm installation platform 300 is a frame steel structure; the oil loading arm installation platform 300 is located on one side of the oil separator body 1; this facilitates the rapid construction of the oil loading arm installation platform 300 and the installation and arrangement of other equipment.

[0067] Furthermore, the oil loading arm installation platform 300 is also provided with a staircase 3001, which is used to facilitate personnel to climb to the top of the oil loading arm installation platform 300 and observe the interior of the oil separator body 1 from below; thereby making the port oil transportation system of this embodiment a convenient, safe, and environmentally friendly operating system.

[0068] Specifically, according to the port oil transfer system of this embodiment, regardless of winter or summer, following the process flow and operation time of the time sequence diagram, with the support of electric heating heat transfer oil heat exchange and demulsifier, the main body of the oil separator can complete the processing of 200m³ and 300m³ of oily wastewater every two days, producing six truckloads and eight truckloads of waste oil; regardless of winter or summer, the energy consumption of electric heating + the energy consumption of heat transfer oil circulation heat pump will not exceed 150 kW and 300 kW;
