Abstract
An explosion-proof heating insulation box of an oil well mouth, which is used for insulation of the oil well mouth in winter and integrates heating and insulation functions. The heating and heat-insulating box body is composed of two symmetrical halves which are connected together through a fastener. The electric heater assembly is embedded in the inner wall of the box body, so that heat generated by the electric heater assembly is supplied to the interior of the box body, and the electric heater does not need to be arranged at a wellhead during use. The heating device can be an electric heating belt or an electric heating pipe. The heater assembly is provided with an explosion-proof junction box, a temperature sensor, a temperature controller and a temperature control switch which are arranged in the explosion-proof junction box and used for controlling the work of a heating device. The heat-insulating layer in the middle of the box body is made of fireproof materials. The heating and heat preservation integrated function can be realized, the heat preservation process is simplified, and the safety and reliability are improved.
Description
Technical field
The utility model relates in a kind of oil field oil recovery manufacturing process, the incubator of developing for heating in well mouth of oil well winter and insulation.
Background technology
In north cold area recovered the oil manufacturing process winter, the crude oil in the well mouth of oil well device was in lower temperature, its viscosity increased, and mobile decline caused the obstruction of oil gas, influences output.At present, all adopt incubator that wellhead assembly is incubated, existing incubator has only heat insulation function, must increase simultaneously the electric heater heating that heats up during use on wellhead assembly, and its casing connects and uses screw perforation to connect, and on-the-spot warming technology is complexity.
Summary of the invention
In order to simplify warming technology, overcome the deficiency of existing incubator, the utility model provides a kind of and has integrated heating and be incubated the explosion-proof heater incubator of the well mouth of oil well that can connect fast.This heater incubator cabinet wall has embedded explosion-proof electric heater component, need not electric heater be installed again at well head when using incubator, and casing connects the employing fastener and connects.
The technical scheme that its technical problem that solves the utility model adopts is: thermal insulation box body is split type for symmetry, and the heater that casing is embedded in produces heat and offers box house.In the electric heater component that on casing, embeds, comprise the temperature-control protector part, sensor, temperature controller, temperature detect switch (TDS) are arranged, play the effect of control heater spare duty.Sensor cooperates the control heating-up temperature with temperature controller, in a single day temperature controller lost efficacy, and when temperature reached maximum permissible temperature, temperature detect switch (TDS) can be cut off the electricity supply, and realized safe effect.Insulation layer in the middle of the heat tracing casing uses fire proofing material, and casing connects the employing fastener casing is linked into an integrated entity.
The beneficial effects of the utility model are: realized the heat tracing function that is integrated in one, casing can connect fast, dismounting, has simplified warming technology, has improved security reliability.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples
Fig. 1 is a sectional structure chart of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
1. casing inner panels among the figure, 2. casing outside plate, 3. fire-retardant heat-insulation material, 4. anti-explosion electric heater assembly, 5. anti-explosion terminal box, 6. temperature pick up, 7. temperature controller, 8. temperature detect switch (TDS), 9. casing, 10. connection fastener.
The specific embodiment
In Fig. 1, two fan casings (a 9) wherein side are located near casing inner panel (1), embed anti-explosion electric heater assembly (4), and the general power of electric heater is 200-1000Kw; Its underpart is provided with anti-explosion terminal box (5) for one jiao, interior dress temperature temperature detect switch (TDS) (8), temperature pick up (6), temperature controller (7).Sensor (6) and temperature controller (7) cooperating play the effect of control heater spare (4) heated condition.In case temperature controller (7) lost efficacy, temperature rises when reaching maximum permissible temperature, and temperature detect switch (TDS) (8) can be cut off the electricity supply.Heat-insulation and heat-preservation material (5) adopts fire proofing material, as rock wool, glass wool etc.For keeping two fan casings in conjunction with tight, mismatch or tenon mouth overlapping mode are adopted in the junction, rely on connection fastener (10) to close up, lock together use.
Electric heating device (4) can be the ribbon heater, also can be electrothermal tube.
Claims (4)
1, the explosion-proof heater incubator of a kind of well mouth of oil well is characterized in that: incubator is split type for symmetry, embeds explosion-proof heater assembly at cabinet wall.
2, the explosion-proof heater incubator of narrating according to claim 1 of well mouth of oil well is characterized in that: tenon mouth or mismatch overlapping mode are adopted in two fan casing junctions, and some connection fasteners are installed.
3, the explosion-proof heater incubator of narrating according to claim 1 of well mouth of oil well, it is characterized in that: explosion-proof heater assembly bottom is provided with an anti-explosion terminal box.
4, the explosion-proof heater incubator of narrating according to claim 3 of well mouth of oil well is characterized in that: anti-explosion terminal box inside is furnished with a temperature controller and a temperature detect switch (TDS).
