Description

Electric heater

The utility model relates to the employed a kind of electric heater of a kind of oil field shaft mouth discharging oil.

Oil is human necessity, and it is widely used in industry, agricultural and the vehicle transport.During recover petroleum,, therefore in the oil pipeline of oil field shaft mouth, all be provided with heater, the viscosity of oil reduced, so that the smooth discharge of oil because oil viscosity is bigger.Existing employed heater all adopts an airtight housing, its both sides have inflow entrance and link to each other with flow export and with petroleum pipeline, be provided with calandria in the described housing, as heating wire, electrothermal tube, electric backing plate, ceramic cladding formula heating element, to reach the reduction oil viscosity.The shortcoming of this heater is: the oil that is input in the housing can not get sufficient heating, and the heat efficiency is low, power consumption is big, has naked light short useful life.

The purpose of this utility model provides heat exchange process, the saving electric energy that a kind of heat exchange effect is good, increase fluid, a kind of electric heater of flames of anger long service life.

The utility model is achieved in that a kind of electric heater, comprise tank body, the sidewall of tank body and upper end are respectively equipped with inflow entrance and flow export, it is characterized in that: the both ends in the described tank body are provided with division board tank body are separated into down cavity, tank body lumen and upper plenum, on described, following cavity is communicated two cavitys by a branch of heat pipe, be provided with guide shell in the described upper plenum, this guide shell will separate each other near the heat pipe of central part and the heat pipe of peripheral part, internal layer chamber and outer chamber have been formed, the peripheral part of the last division board in the described tank body has the stream hydraulic fluid port, on described, the internal face of following division board is provided with a wire connection cavity that surrounds the heat pipe end, be provided with one between two wire connection cavities for the metal tube that the electric wire turnover is installed, described going up on the division board is connected to conduit, one port of this conduit passes outside the tank body, the another port communicates with conductor chamber, described heat pipe comprises an interior heating tube, be coated with semiconductor thermoelectric film on the periphery wall of interior heating tube, be with outer heating tube on this Electric radiant Heating Film, the place, two ends of described Electric radiant Heating Film passes through metal tube by lead, conduit links to each other with power supply.Be provided with one group of semi-circular deflection plate in the described tank body lumen, this deflection plate is upper and lower to be staggered.

The utility model mainly is that division board has been set up at the two ends in tank body, make in the tank body and be divided into, in, isolated down cavity, in the described tank body lumen a branch of heat pipe is installed, and with last, following cavity communicates, be provided with guide shell in the upper plenum, the heat pipe of central part and peripheral part is isolated, the described division board peripheral part of going up is provided with the stream hydraulic fluid port, the tank body lumen is communicated with last outer chamber, be provided with deflection plate across in the described tank body lumen, when liquid when inflow entrance enters the tank body lumen, just formed a S shape runner, after liquid enters outer chamber from the stream hydraulic fluid port of last division board, endoporus by the peripheral part heat pipe from top to bottom enters down cavity, from bottom to top enters the internal layer chamber again, discharges by flow export at last, can increase flow process like this, make the heat exchange of fluid more abundant.Described heat pipe, comprise an interior heating tube, the periphery wall of interior heating tube is coated with semiconductor thermoelectric film, at the two ends of Electric radiant Heating Film extraction electrode heating element, be with outer heating tube on the described Electric radiant Heating Film, because the utility model adopts Electric radiant Heating Film to make calandria, can improve the efficiency of heating surface, save electric energy, this Electric radiant Heating Film is a planar heat producing body, can form thermal conductive surface to greatest extent with heated object.

The utility model compared with prior art has following advantage, and heat-conductive characteristic is good, and the flames of anger, long service life, what mode of heating of the present utility model adopted is the tubulation dividing wall type, compare with heat exchanger commonly used, its heating procedure improves a lot, and has increased heat exchange area.The utility model can make the crude oil temperature of petroleum pipeline and oil storage tank improve, and reduces viscosity of crude, thereby has strengthened the conveying capacity of crude oil.The utility model is specially adapted to viscous crude, the high heat temperature raising that coagulates oil.

Drawing is described as follows:

Fig. 1 is the utility model sectional structure schematic diagram.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Referring to accompanying drawing, as can be seen from the figure, the utility model comprises a tank body 10, the sidewall of tank body 10 and upper end are respectively equipped with inflow entrance 3 and flow export 19, the bottom of tank body is provided with bearing 1, both ends in the tank body are provided with division board 21,4, this division board is separated into down cavity 2 with tank body, tank body lumen 6 and upper plenum, being provided with a branch of heat pipe 7 in the tank body lumen 6 also will go up, following cavity is communicated with, be provided with guide shell 17 in the described upper plenum, this guide shell 17 will separate each other near the heat pipe 8 of central part and the heat pipe 9 of peripheral part, internal layer chamber 18 and outer chamber 16 have been formed, the described peripheral part of going up division board 21 is laid with stream hydraulic fluid port 15, on described, following division board 21,4 internal face is provided with a wire connection cavity 23 that surrounds heat pipe 7 ends, 5, on, following wire connection cavity 23, be provided with one between 5 for the metal tube 24 that the electric wire turnover is installed, be connected to a conduit 20 on the described wire connection cavity 23, one port of this conduit 20 passes tank body 10, the another port communicates with wire connection cavity 23, described heat pipe comprises an interior heating tube 14, the periphery wall of interior heating tube 14 is coated with semiconductor thermoelectric film 13, be with outer heating tube 12 on this Electric radiant Heating Film 13, the place, two ends of described Electric radiant Heating Film 13 passes through metal tube 24 by lead 22, conduit 20 links to each other with power supply.Be provided with the semi-circular deflection plate 11 of mutual cross arrangement in the described tank body lumen 6.During use, when liquid enters tank body lumen 6 from inflow entrance 3, because the effect of deflection plate 11, fluid is made broken line and is flowed in tank body lumen 6, simultaneously do uniform heat exchange by outer heating tube 12 convection cells, after fluid enters outer chamber 16 from stream hydraulic fluid port 15, in the interior heating tube 14 of periphery heat pipe 9, pass again, from top to bottom flow to down cavity 2, pass in the interior heating tube by central part heat pipe 8 again, from bottom to top flow to internal layer chamber 18, and discharge, so just constituted a complete electric heater by flow export 19.
