Abstract
The utility model discloses a centrifugal filtration type crude oil spiral plate heat exchanger which comprises a sealed casing. A spiral heat exchanging element and a centrifugal filter are arranged in the sealed casing from top to bottom, the spiral heat exchanging element is formed by two spiral bodies arranged in an intersecting mode, the centrifugal filter is communicated with a spiral channel of the spiral heat exchanging element, a cold medium outlet and a hot medium inlet are formed in the upper end of the sealed casing, a silt discharging opening is formed in the lower end, a cold medium inlet and a hot medium outlet are formed in the lateral wall, the cold medium inlet is communicated with an inlet of the centrifugal filter, the hot medium outlet and the hot medium inlet are connected with the two ends of another spiral channel of the spiral heat exchanging element respectively, and the silt discharging opening is communicated with the centrifugal filter. The centrifugal filter is added at the position of an original inlet, silt in crude oil is separated to the bottom of the device to be periodically discharged, and the content of the silt entering the crude oil of the heat exchanger is reduced to below 80%.
Description
Technical field
The utility model relates to technical field of heat exchangers, especially a kind of centrifugal filtration formula crude oil plate coil (exchanger).
Background technology
Plate coil (exchanger) is because heat exchange efficiency is high, easy cleaning after passage fouling, be widely used in the preheating delivery technology of crude oil, but owing to containing a large amount of silt particles in crude oil, and the instability of flow of crude oil, flow velocity is less than in the situation of 1m/s, silt particle in crude oil easily deposits in the passage of heat exchanger, result in blockage, have a strong impact on the continuous operation of heat exchanger, to operation maintenance, cause very large difficulty.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of centrifugal filtration formula crude oil plate coil (exchanger), and structure is ingenious, and efficiency is high.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of centrifugal filtration formula crude oil plate coil (exchanger), comprise seal casinghousing, in sealing housing, be provided with conveyor screw heat exchange element and centrifugal type filter from top to bottom, this spiral heat exchange element consists of two conveyor screws arranged in a crossed manner; This centrifugal type filter is communicated with a helical duct of conveyor screw heat exchange element; Sealing housing upper end is provided with cold media outlet and thermal medium entrance, and lower end is provided with sand removing hole, and sidewall is provided with cold medium inlet, thermal medium outlet; Cold medium inlet is communicated with centrifugal type filter entrance, and thermal medium entrance and exit is connected with another helical duct two ends of conveyor screw heat exchange element respectively, and sand removing hole is communicated with centrifugal type filter.
Compared with prior art, the utlity model has following advantage: in original entrance location, increased centrifugal filtration device, the bottom periodic cleaning that silt in crude oil is separated to equipment by centrifugal filter device is discharged, and the silt content that makes to enter in the crude oil of heat exchanger reduces to below 80%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of conveyor screw heat exchange element.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of centrifugal filtration formula crude oil plate coil (exchanger) as illustrated in fig. 1 and 2, comprise seal casinghousing 4, in sealing housing 4, be provided with conveyor screw heat exchange element 3 and centrifugal type filter 7 from top to bottom, this spiral heat exchange element 3 consists of two conveyor screws arranged in a crossed manner, as shown in Figure 2; This centrifugal type filter 7 is communicated with a helical duct of conveyor screw heat exchange element 3; Sealing housing 4 upper ends are provided with cold media outlet 2 and thermal medium entrance 1, and lower end is provided with sand removing hole 8, and sidewall is provided with cold medium inlet 5, thermal medium outlet 6; Cold medium inlet 5 is communicated with centrifugal type filter 7 entrances, and thermal medium entrance 1 is connected with conveyor screw heat exchange element 3 another helical duct two ends respectively with outlet 6, and sand removing hole 8 is communicated with centrifugal type filter 7.
Cold medium (crude oil) centrifugal type filter of flowing through, separated by helical duct, after centrifugal filtration, flow out outlet, and the foreign material such as silt particle enter the outlet of rapid strainer, by blowdown apparatus, regularly discharged, blowdown apparatus also can regular dismounting, cleaning, has greatly improved heat transfer efficiency and service life of equipment.
1. adopt centrifugal filtration formula crude oil plate coil (exchanger), solved heat exchanger and easily stopped up, the problem that running time is short, has solved field heat exchanger and has keeped in repair difficult problem, has greatly improved heat transfer efficiency and service life of equipment.Guarantee that equipment continuous effective reaches more than 360 days running time, save maintenance fund more than 50%, increase economic efficiency 30%.
This product is on the basis of original non-disconnectable spiral heat exchanger, in original entrance location, increased centrifugal filtration device, the bottom periodic cleaning that silt in crude oil is separated to equipment by centrifugal filter device is discharged, and the silt content that makes to enter in the crude oil of heat exchanger reduces to below 80%.
