Abstract
The utility model provides a large-scale coke tower material level continuous measurement device, by coke tower 1, gamma radiation source 2, cross valve 3, go up detector 4, detector 5 is constituteed down, the utility model discloses owing to adopt to connect 3 gamma radiation sources respectively in two coke tower outsides, connect detector, detector down respectively in two coke tower inboards. The height of the raw coke of the coke tower can be accurately reflected, the height of the foam layer is visually displayed, the injection amount of the defoaming agent can be conveniently and timely adjusted to reduce the height of the foam layer, and the foam is effectively prevented from being caused by overflow from the top of the tower. The method provides a powerful basis for accurately judging and formulating the time for switching the coke tower, can visually see the change of the water level when the old tower treats the feed water, accurately judges the time for changing the overflow and ensures the safe production of the device. The structure is simple, the material is saved, and the cost is lower. The installation is simple and convenient, saves space, and the radiation is less, and is less harmful to human bodies. No pollution, low energy consumption and great benefit, and is very suitable for on-site popularization and application.
Description
Technical field:
The utility model relates to a kind of petrochemical complex and produces the measurement mechanism of going up use, particularly a kind of large-scale coke tower material level continuous measuring device.
Background technology:
For a long time, the delayed coking unit green coke height of coke drum in process of production can't onlinely be measured, and can only obtain when decoking, seriously lags behind production.Therefore when bigger variation took place feedstock property, coke drum green coke height can only estimate by rule of thumb that potential safety hazard is bigger.Use neutron level-sensing device commercial measurement, a radioactive source and detector only are installed on coke tower.Radiation is strong, and is big to human body harm.And can't realize continuous coverage.
Technical scheme
The utility model purpose is to provide a kind of large-scale coke tower material level continuous measuring device.The green coke height that can reflect coke tower accurately has intuitively the height of froth bed to show that radiation is less, and is less, pollution-free to human body harm.Energy consumption is low, and income is big.
The utility model purpose is to realize like this, it is made up of coke tower (1), gamma ray radiator (2), four-way valve (3), last detector (4), following detector (5), in the upper and lower binding respectively of two coke towers (1), it connects by four-way valve (3) down, be connected to 3 gamma ray radiators (2) respectively in two coke towers (1) outside, be encapsulated in 3 chests, have only a hole on the chest, be connected to detector (4), following detector (5) in two coke towers (1) inboard respectively.
During work, ray penetrates from the hole, passes coke tower, gets on the detector on the right, passes the quantity and the intensity of coke tower according to ray and measures material level accurately.On DCS, make simultaneously corresponding point and configuration, accurately coke tower green coke height and feedwater highly are reflected on the DCS picture.
The utility model is connected to detector, following detector respectively because employing is connected to 3 gamma ray radiators respectively in two coke towers outsides two coke tower inboards.The green coke height that can reflect coke tower accurately has intuitively the height of froth bed to show, the injection rate IR of being convenient in time to adjust defoamer reduces the height of froth bed, prevents that effectively foam from leading to a disaster from the cat head overflow.Provide strong foundation for accurately judging, when old tower is handled feedwater, can see the variation of water level intuitively, accurately judged the time that changes overflow, guaranteed the safety in production of device with working out the time of switching coke tower.It is simple in structure, saves material, and cost is lower.Simple installation is saved the space, need not perforate on equipment, perforating.Radiation is less, and is less to human body harm.Pollution-free.Energy consumption is low, and income is big, is well suited for field popularization application.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
As shown in the figure, the utility model is made up of coke tower 1, gamma ray radiator 2, four-way valve 3, last detector 4, following detector 5, at 30.4 meters, 36.6 meters, 40.06 meters of two coke towers 13 γ sources are installed respectively, be encapsulated in 3 chests, the hole of having only a diameter 20mm on the chest faces coke tower 1.Ray penetrates from the hole, passes coke tower 1, gets on the last detector 4 on the right, the following detector 5, passes the quantity and the intensity of coke tower according to ray and measures material level accurately.On DCS, make simultaneously corresponding point and configuration, accurately coke tower green coke height and feedwater highly are reflected on the DCS picture.Be positioned at 30.4 meters bottom, be instantaneous flow, as long as coke layer height or water level surpass time place, last this point of DCS promptly becomes green by redness.And be continuous quantity between 36.6 meters to 40.06 meters, can show the situation of discharge of the coke layer or water level rising accurately.
In chemical industry, solve the level gauging problem of large-scale plant, as the level gauging of the coke tower of 8.4 meters of coker diameters, the level gauging of polypropylene reactor etc.Can be in real time accurately with measurement feedback on the DCS monitoring system, thereby the result dataization that relies on empirical analysis to draw before making, sharpening, accuracy, the operative employee is got information about the variation of thing position, make accurately and judging, can adjust operation timely, guarantee safety and steady production.
The green coke height that can reflect coke tower accurately has intuitively the height of froth bed to show, the injection rate IR of being convenient in time to adjust defoamer reduces the height of froth bed, prevents that effectively foam from leading to a disaster from the cat head overflow.Provide strong foundation for accurately judging, when old tower is handled feedwater, can see the variation of water level intuitively, accurately judged the time that changes overflow, guaranteed the safety in production of device with working out the time of switching coke tower.
Claims (1)
1, a kind of large-scale coke tower material level continuous measuring device, it is made up of coke tower (1), gamma ray radiator (2), four-way valve (3), last detector (4), following detector (5), it is characterized in that: in the upper and lower binding respectively of two coke towers (1), it connects by four-way valve (3) down, be connected to 3 gamma ray radiators (2) respectively in two coke towers (1) outside, be encapsulated in 3 chests, have only a hole on the chest, be connected to detector (4), following detector (5) in two coke towers (1) inboard respectively.
