Abstract
The utility model discloses an energy-saving and safety control device of gas furnace in the oilfield for petroleum industry, and is suitable for the oil production wells used in heating and transportation of the crude oil by the gas furnace. The device comprises a safety valve. The natural gas is introduced into the bottom of the furnace body for combustion through a feed piping and a control valve, and on the feed piping is equipped with a gas control system. The controller is communicated with an oil temperature sensor, a water temperature sensor and the gas control system by cables. The utility model solves many problems including no precise control of oil discharge temperature, burnt furnace, poor security and waste of energy of existing heating system of the gas furnace during the transportation of the crude oil in the oilfield, so as to achieve the purposes of protection of equipment and safe production.
Description
Technical field
The utility model relates to the oil production equipment of petroleum industry, and particularly oil field gas-fired heater energy-saving safety control device is applicable to and adopts gas-fired heater to carry out the producing well that heating crude oil is carried.
Background technology
Heating furnace is the visual plant in the crude oil production process, at measuring station to the course of conveying of multi-purpose station, for the mode of movement that easily coagulates, highly viscous crude generally adopts big heating furnace heating, prevent that crude oil from solidifying in course of conveying, reduce viscosity, reduce the friction loss of crude oil in course of conveying.Current, the big heating furnace in the most of oil field of China uses generally that isolated natural gas acts as a fuel from crude oil.Heating furnace often is located in open-air no staff on duty, and for a long time, because the low Crude Oil Transportation that influences of outlet temperature, the interior lack of water of heating-furnace burns out accident potential such as heating furnace becomes a persistent ailment.The energy does not obtain more effectively utilizing, and waste is serious.Problems such as traditional heating stove control method exists that stove fire can't be regulated, defencive function imperfection, burning are insufficient, source of the gas instability.Because the source of the gas instability, the self-extinguishing phenomenon happens occasionally, and safety in production can not get abundant assurance.Because big heating furnace uses comparatively general in northern oil field; most heating furnaces have only been installed safety valve in order to pressure protect to be provided; when natural atmospheric pressure changes; when stove fire is big; the temperature of the thermal medium in the heating furnace---water constantly raises; a large amount of water vapours cause the body of heater internal pressure to raise gradually; when pressure exceeds alarm setting value; the safety valve action; steam is discharged; if in time do not find this moment to take measures or safety valve in the temperature extremes akinesia, can cause heating furnace blast even more serious security incident to take place.And general combustion control system costs an arm and a leg at present, can't apply on a large scale, and most heating furnaces are still worked under the situation that lacks effective protection and control device, adopt artificial manual control.
Summary of the invention
The purpose of this utility model provides oil field gas-fired heater energy-saving safety control device, overcomes that existing heating furnace stove fire can't be regulated, defencive function imperfection, insufficient, the source of the gas problem of unstable of burning.Make full use of the energy, protection equipment, safety in production.
Following technical proposals can reach above-mentioned purpose: oil field gas-fired heater energy-saving safety control device comprises safety valve, natural gas enters the base burning of body of heater by admission line and control valve, the combustion gas controlling organization is installed on admission line, and controller is connected with oil temperature sensor, cooling-water temperature sensor and combustion gas controlling organization by cable.
The utlity model has following useful effect: this device possesses perfect control and defencive function, can increase substantially thermal efficiency of heating furnace and security performance, and compact conformation is simple to operate, and the equipment input cost is low.Simplify the execute-in-place program simultaneously, increase work efficiency, fully ensured the person and device security, accomplish safety in production, reduce labor strength greatly.Regulate and control the size of each air inlet pipeline gas transmission by controller and magnetic valve, solved in the crude oil course of conveying, the oil outlet temperature that the heating furnace heating system exists can't accurately be controlled, stove burns, and poor stability, problems such as waste energy.
Description of drawings
Accompanying drawing is an assembling scheme of installation of the present utility model.
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: oil field gas-fired heater energy-saving safety control device comprises safety valve 4, natural gas enters the base burning of body of heater 6 by admission line and control valve 13, the combustion gas controlling organization is installed on admission line, and controller 2 is connected with oil temperature sensor 1, cooling-water temperature sensor 5 and combustion gas controlling organization by cable.The combustion gas controlling organization comprises air inlet pipeline 7,8 and 9, and air inlet pipeline 7,8 and 9 is in parallel with control valve 13 and admission line.Connecting respectively on the air inlet pipeline 7 and 8 control valve 10 and magnetic valve 11; Connecting on the air inlet pipeline 9 control valve 10 and pressure maintaining valve 12; Magnetic valve 11 is connected with controller 2 by cable.Oil temperature sensor 1 is installed in the oil outlet end of the coil pipe 3 of body of heater 6 outsides; Cooling-water temperature sensor 5 is installed in the outside of body of heater 6, and its feeler lever is deep in the water in the body of heater 6, detects water temperature.Crude oil enters, spirals in the water of body of heater 6 by coil pipe 3 from the oil inlet end of coil pipe 3, and absorption is heated the heat of water, and the crude oil after the heating flows out from the oil outlet end of coil pipe 3.
During daily use, control valve 13 is closed, and only just opens when combustion gas controlling organization maintenance of the present utility model, allows natural gas via control valve 13 enter the base burning of body of heater 6, plays standby effect.During by 2 conducting air inlet pipelines 9 of controller is little fire, and air inlet pipeline 9 and 8 is a moderate heat during conducting all, is big fire when air inlet pipeline 9,8 and 7 whole conductings, constitutes three grades of firepower thus.Control valve 10 can be distinguished the air demand of three air inlet pipelines of manual adjustments 7,8 and 9, thus the size of regulating three grades of firepower.Controller 2 is selected little fire, moderate heat, big fire by the opening and closing of controlling two magnetic valves 11.Controller 2 is gathered water temperature and oil temperature by cooling-water temperature sensor 5 and oil temperature sensor 1.Controller 2 has load button, can set for the user, import oily temperature desired value, has LCD.Show oil temperature, water temperature, running status and firepower size in real time.Controller 2 was done once and is judged in per 10 minutes, and when oil temperature during greater than 5 ℃ of user's target value set, controller 2 will progressively reduce firepower by regulation and control magnetic valve 11.When oil temperature during less than 5 ℃ of user's target value set, controller 2 will progressively strengthen firepower.When water temperature surpassed 92 ℃, controller 2 was transferred to little fire with firepower, the vaporization of anti-sealing.
