Description
(1) technical field
The present invention relates to a kind of oil assay apparatus, particularly a kind of protected against explosion crude oil water containing analyzer.
(2) background technology
In present petrochemical industry, the mensuration of water content in crude oil usually realizes according to the international method of distillation that adopts, but in the process of distillation to the determining instrument of its heating arrangement and control device, but exist many defectives.
Because it is relatively stricter that petrochemical industry requires anti-explosion fire, but the heating of present crude oil water containing analyzer and control section are normally wrapped up in the electric jacket heating of glass fiber crocheted outward by resistance wire, realize control by some electrical equipments.After electric jacket used a period of time, glass fiber came off, and produced naked light, and in case splash into moisture and be short-circuited, fire hazardous causes the accident; And resistance wire easily blows cisco unity malfunction after use a period of time.
(3) summary of the invention
The present invention provides a kind of simple in structure, safe protected against explosion crude content analyzer in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of protected against explosion crude oil water containing analyzer, comprise housing, heating arrangement and be connected the explosion-proof control box of heating arrangement, it is characterized in that: described heating arrangement is that inside surface is hemispheric heating shell, heating shell and explosion-proof inner casing weld and form the heat conduction oil pocket up and down between the two, the outer connection of explosion-proof inner casing is covered with explosion-resistant enclosure, explosion-proof inner casing is provided with lubrication hole, and electric heating tube and heat pipe are installed in the heat conduction oil pocket; Be provided with the temperature control instrument, A.C. contactor, electric switch and the pilot lamp that connect successively in the explosion-proof control box; Temperature sensor is installed in the heat pipe, and temperature sensor stretches out heating arrangement by the cable sealed joint on the explosion-resistant enclosure, and is connected with temperature control instrument.
The present invention is provided with the heat conduction oil pocket between heating shell and explosion-proof inner casing, and places electric heating tube, is used to heat conduction oil, thereby the heating heating shell in addition, is used for the laying temperature sensor by a heat pipe is set, and is used for measurement and control to conduction oil.
Control between heating arrangement and the explosion-proof control box realizes by stube cable.In the course of the work, temperature control instrument constantly detects the evil temperature of conduction oil, and compares with the temperature of setting, if be lower than the temperature of setting, control output energized, begin heating, if surpass design temperature, control output stops heating, as occur unusual, heating-up temperature surpasses last upper limit alarm setting value, and general supply is cut off in control output, could recover normal behind the Awaiting Overhaul.
More excellent scheme of the present invention is:
Described heating shell is made of double-layer stainless steel.
Described housing is provided with the retaining valve that is communicated with the heat conduction oil pocket.
Described explosion-proof inner casing is connected by bolt with explosion-resistant enclosure.
The present invention is simple in structure, and is safe in utilization, the accuracy of detection height, and long service life is a kind of new type measuring instrument device that is applicable to the quantitative determination of petrochemical industry crude oil water containing, and has passed through the evaluation of national explosion-proof evaluating center, has obtained conformity certificate of protection.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of heating arrangement of the present invention;
Fig. 3 is an electrical schematic diagram of the present invention.
Among the figure, 1 housing, 2 heating arrangements, 3 explosion-proof control boxs, 4 heating shells, 5 explosion-proof inner casings, 6 heat conduction oil pockets, 7 explosion-resistant enclosures, 8 lubrication holes, 9 electric heating tubes, 10a, 10b temperature control instrument, 11 cable sealed joints, 12 retaining valves, 13 bolts.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises housing 1, heating arrangement 2 and is connected the explosion-proof control box 3 of heating arrangement 2, described heating arrangement 2 is hemispheric heating shell 4 for inside surface, heating shell 4 welds and forms heat conduction oil pocket 6 up and down between the two with explosion-proof inner casing 5, explosion-proof 5 outer connections of inner casing are covered with explosion-resistant enclosure 7, explosion-proof inner casing 5 is provided with lubrication hole 8, and electric heating tube 9 and heat pipe are installed in the heat conduction oil pocket 6; Be provided with the temperature control instrument 10, A.C. contactor, electric switch and the pilot lamp that connect successively in the explosion-proof control box 3; Temperature sensor is installed in the heat pipe, and temperature sensor stretches out heating arrangement 2 by the cable sealed joint on the explosion-resistant enclosure 7 11, and is connected with temperature control instrument 10; Described heating shell 4 is made of double-layer stainless steel; Described housing 1 is provided with the retaining valve 12 that is communicated with heat conduction oil pocket 6; Described explosion-proof inner casing 5 is connected by bolt 13 with explosion-resistant enclosure 7.
Before analyzer uses, earlier that various articles for use are ready, the condenser pipe support is inserted in the hole at two ends above the instrument platform, again the condensation pattern is inserted in the bracket loop, check then whether condenser pipe and receiver, heating shell 4 be vertical, whether flexible twitch up and down, otherwise should correct; At last the intake-outlet of condenser pipe and soft water conduit is connected, so just finished the preliminary work of measuring.
Various preliminary works finish, the energized switch, and the control section of system begins self check, enter mode of operation after all are normal, when needing to set heating-up temperature, the SET instrument of push key enters the state of setting, the selection temperature is provided with, and the operation increasing-and-decreasing key is finished the temperature setting.
After finishing various the setting, instrument enters normal measurement state of a control, and operating personnel wait for the end of a complete course of work.
In the course of the work, the control of temperature control instrument 10a output is used for adding normally heat control, and when temperature was lower than setting value, heater heats stopped heating when being higher than setting value; Another one temperature control instrument 10b is used for out-of-limit alarm control, if temperature control instrument 10a occurs unusual, when heating-up temperature was higher than the out-of-limit alarm set value of another temperature control instrument 10b, a pair of normally closed contact T2 of temperature control instrument 10b disconnected system cut-off.
