Abstract
The utility model relates to a hot sleeve pressure container type detecting device used for measuring the actual weight water level of a steam drum of a steam boiler. The hot sleeve pressure container type detecting device is characterized in that a hot sleeve pressure container is used for replacing a single tube pressure container, and the hot sleeve pressure container is in a sleeve tube structure; an inner tube changes the water level, and an outer tube bears pressure; the water temperature of the inner tube is extremely close to saturation temperature, and therefore, the displayed water level is the weight water level of saturated water in the steam drum. When the water level of the steam drum of a 670 T/h superhigh pressure boiler is a normal value, the maximum error of the water level displayed by the device is 4.6 millimeters and is 70 to 110 millimeters smaller than that of a mica water gauge, and is 50 to 70 millimeters smaller than that of a single tube pressure container type water level detecting device.
Description
The utility model relates to a kind of hot jacket pressure vessel type pick-up unit that is used to measure steam boiler drum actual weight water level.
The general known device that is used to measure steam boiler drum normal water level as mica water column, glass water column etc., by measuring the water level in the connection container that joins with drum, shows the normal water level of drum indirectly.This class directional error is bigger, and displayed value is on the low side, and boiler pressure is big more, and boiler water level is high more, and environment temperature is low more, and the amount of deflection is big more.
In recent years, Britain adopts HydrasteP measurement device steam boiler drum normal water level, and this device is a single tube pressure vessel type boiler water level pick-up unit.The single tube pressure vessel of this device has two effects of pressure-bearing and change water level concurrently, and thickness of pipe, diameter are big, and SEA LEVEL VARIATION speed is slow, the saturation temperature of water temperature under the relevant pressure, and the severe of water substantially exceeds saturation water severe.Boiler water level that this device is shown and drum actual weight water level differ bigger.
The purpose of this utility model is a kind of hot jacket pressure vessel type pick-up unit that is used to measure steam boiler drum actual weight water level of design, make it to satisfy the fireballing requirement of high parameter heavy duty boiler SEA LEVEL VARIATION, and can remedy above-mentioned boiler-steam dome normal water level pick-up unit, take into account deficiency on the single tube pressure vessel type boiler water level pick-up unit function as mica water column, the glass water surface.
Characteristics of the present utility model are to adopt the hot jacket pressure vessel to replace the single tube pressure vessel, and the hot jacket pressure vessel is a sleeve structure, an interior pipe change water level, and outer tube pressure-bearing.Diameter of inner pipe can be done very carefully, thereby reaches the purpose of timely change water level.If is example with 50 millimeters of SEA LEVEL VARIATION, hot jacket pressure vessel SEA LEVEL VARIATION will be than single tube pressure vessel fast 3 times.The interior pipe water temperature utmost point of hot jacket pressure vessel is bordering on saturation temperature, so the water level that shows is the weight water-level of saturation water in the drum.When 670 tons/time superpressure boiler steam water-level during at normal value, water table ratio single tube pressure vessel reaction water bit error is little 50～70 millimeters in the hot jacket pressure vessel, and is littler 70～110 millimeters than mica water column error.
The utility model is made up of hot jacket pressure vessel and electric contact, and the hot jacket pressure vessel is a sleeve structure, pipe and outer tube two parts in comprising, and interior pipe downside links to each other with drum water side, and inside and outside two pipe tops all communicate with the vapour side of drum.Interlayer between two pipes constitutes steam jacket, is full of saturated vapour.Water in saturated vapour simultaneously heats in the pipe makes it the temperature that reaches capacity, and one side condenses into water and flows into downtake.Under saturation temperature, the water level of interior pipe equals the weight water-level in the drum.
Four regularly arranged vertically row electric contacts are housed, the height of pipe water level in can directly measuring on the inner tubal wall of hot jacket pressure vessel.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a hot jacket construction of pressure vessel assembling synoptic diagram of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the utility model installation system synoptic diagram.
With reference to Fig. 1～3, hot jacket pressure vessel of the present utility model is made up of interior pipe (3) and outer tube (4) two parts, inside and outside two pipe forming sleeves structures.Outer tube (4) top is sealed by upper cover (10), the bottom is linked to each other with blow-off pipe (1) by low head (2), blowdown connects short tube (11) and connects low head (2) and interior pipe (3) lower end closure plate (13), and interior pipe (3) bottom is communicated with blow-off pipe (1).Interior pipe (3) downside has a valve pipe of water side (5) to communicate with boiler-steam dome (16) water side.Outer tube (4) upside has drainage tube (12) to communicate with drum downtake (20).Hyponome (15) is with fixed attention arranged in the inner chamber of outer tube (4) top, and its end opening is suitable for reading relative with interior pipe (3).On outer tube (4) wall, have along the regularly arranged four row electric contact seats (7) (totally 19) of the axis direction of pipe.Each electric contact seat (7) all has connection short tube (6) to be communicated with interior pipe (3) inner chamber and is fixed on the tube wall, and these connect short tube (6) and line up four row vertically regularly on interior pipe (3) wall.Lay an electric contact (8) that passes to interior pipe (3) inner chamber in each electric contact seat (7), in order to measure the height of interior pipe (3) water level.Interlayer between interior pipe (3) and the outer tube (4) is steam jacket (14), is full of saturated vapour.
When the utility model is in normal operating conditions, a valve pipe of the vapour side of hot jacket pressure vessel (19) (9) links to each other with drum (16) vapour side by a valve of vapour side (17), a valve pipe of water side (5) links to each other with drum (16) water side by a valve of water side (22), drainage tube (12) links to each other with drum downtake (20) by lowering valve (21), and blow-off pipe (1) communicates with boiler blow-out system by blowoff valve (23).Each electric contact (8) joins with Displaying Meter (24).Mica water column (18) is connected between drum (16) vapour side and the water side, and is in parallel with hot jacket pressure vessel (19), and the water-head that shows between the two is Δ h.
Through test, hot jacket pressure vessel type boiler water level pick-up unit be used for 670 tons/time during boiler, the water level in the hot jacket pressure vessel is compared with actual weight water level in the drum, maximum error is 4.6 millimeters.The water level that this device shows is not changed by unit parameter and steam water-level influence just, and not with variation of ambient temperature, has satisfied the fireballing requirement of high parameter heavy duty boiler SEA LEVEL VARIATION, has remedied the deficiency on the known boiler water level pick-up unit function.
