Description

Technical Field

[0001] The utility model relates to the technical field of condensing boxes, in particular to a condensing box for a tertiary oil and gas recovery device. Background Art

[0002] Cold box is a set of high-efficiency, heat-insulating and cold-preserving low-temperature heat exchange equipment. It is often used in the process of deep cold separation. For example, in the process of deep cold separation of petroleum cracking gas, a cold box working at about -100 to -140°C is used. It consists of a compact and efficient plate heat exchanger and a gas-liquid separator. Because low temperature is very easy to dissipate cold, extremely strict heat insulation is required, so the heat exchanger and separator are packed in a box-shaped object with insulating materials, which is called a cold box.

[0003] When a traditional condensing mechanism condenses and recovers oil, the oil and gas to be condensed directly enters the condensation box from the air inlet. However, since impurities are usually present in the oil and gas, which can easily affect the quality of the oil, the condensation box of the current oil and gas recovery device cannot filter the oil and gas.

[0004] Therefore, we proposed a condenser box for a tertiary oil and gas recovery device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to solve the problem that oil and gas cannot be filtered.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a condensation box of a tertiary oil and gas recovery device, comprising an inner tank and a condensation pipeline installed in the inner tank, the inner tank is also equipped with an air inlet and an air outlet, a filter cartridge is installed on the air inlet, a filter screen for filtering impurities is installed inside the filter cartridge, a sealing plate is detachably installed at the opening of the filter cartridge, and one side of the sealing plate is fixedly connected to the filter screen, when the oil and gas enter the inner tank through the air inlet, the impurities in the oil and gas are filtered through the filter screen in the filter cartridge.

[0007] Furthermore: the condensation pipeline includes a liquid inlet pipe, a liquid outlet pipe and multiple condensation pipes, and the two ends of the condensation pipe are respectively connected to the liquid inlet pipe and the liquid outlet pipe, and the input end of the liquid inlet pipe and the output end of the liquid outlet pipe both extend to the outside of the inner tank.

[0008] Further: side panels are provided on both sides of the two inner tanks, and two "L"-shaped plate bodies are installed on the two side panels by bolts, and the two side panels and the two "L"-shaped plate bodies constitute a box body for protecting the inner tanks.

[0009] Furthermore: the filter screen is a "cylindrical" structure, and is provided with an opening for use with an air inlet.

[0010] Furthermore: a plurality of mounting seats are fixed on the outer surface of the filter cartridge and the outer surface of the sealing plate at equal intervals along the circumferential direction, and when the sealing plate and the filter cartridge are closed, the two fitting mounting seats are connected by fixing bolts.

[0011] Furthermore: a mounting bracket is installed inside the inner tank, and a plurality of condensing tubes are installed on the mounting bracket.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides a filter in the air inlet. When the oil and gas enter the inner tank, the filter can filter the impurities in the oil and gas to prevent the impurities in the oil and gas from entering the inner tank, thereby improving the purity of the oil and gas; at the same time, it also prevents the impurities from accumulating in the inner tank.

[0014] The present invention uses a new type of filter and sealing plate which are connected in a fixed manner. When the sealing plate is taken out, the filter can be directly driven to be taken out from the air inlet, thereby reducing the operation process of the subsequent staff and bringing convenience to the staff. The filter adopts a "cylinder" structure, so that the impurities in the filter can directly fall into the filter, reducing the cleaning process of the subsequent staff in the air inlet, thereby bringing convenience to the staff.
