Abstract

The utility model relates to a heating stove for raw oil, comprising a housing, a combustor, a combustion chamber and an oil tube. The essential structure is that the oil tube is composed of a wall protecting tube, an inner and an outer coilers, wherein, the wall protecting tube, the inner and the outer coilers are connected in order; the cylindrical combustion chamber is composed of the inner coiler, a plurality of pins which are welded on the inner coiler, and a refractory coating layer; a heat insulating layer is arranged in the columnar housing, and the outer side part of the outer coiler is embedded in a heat insulating layer on the side wall of a furnace body; a partition is arranged in an annular flue. The product has the advantages of simple and compact structure, small size, quick temperature rise, high heat efficiency, long service life and low cost; the utility model can be used for heating well mouths, extracting light oil by dewatering, gathering, etc.

Description

Crude oil heater

The utility model relates to a kind of crude oil heater.

The patent No. is that 94205628 utility model patent specification discloses a kind of " open type radiation furnace ".This oven is compared advantages such as having quick heating, simple to operate, noncoking, low cost of manufacture with the hydroecium oven, but the convective region is a parallel baffled, the heat exchange weak effect, and heat-transfer coefficient is low, and heating surface is arranged and is doted on greatly; Arranged fireproof coating on the chamber wall, but heat can't outwards exchange, be in for a long time under the hot flame, easily scaling loss.

The purpose of this utility model is to provide a kind of quick heating, and is simple in structure, noncoking, and volume is little, the crude oil heater that cost is low.

The purpose of this utility model is achieved by the following technical solution.The utility model comprises housing, burner, firing chamber and oil pipe, its structure outline is: said oil pipe is connected in turn by revetment pipe, inner coil pipe and outer coil pipe, inner coil pipe and several pins and the fireproof coating that are welded on the inner coil pipe are formed throat less chamber, be provided with thermal insulation layer in the barrel-type casing, the lateral part of outer coil pipe is embedded in the thermal insulation layer on the sidewall of the furnace body, and annular flue top is provided with two dividing plates of symmetry.

The utility model is simple in structure, compact, and volume is little, quick heating, and noncoking, thermal efficiency height, long service life, energy saving, cost is low, and can be applicable to well head heating, dehydration, to extract light oil and collection defeated etc., of many uses.

Fig. 1 is a sectional structure chart of the present utility model;

Fig. 2 cuts open structural drawing for a left side of the present utility model office of looking.

The accompanying drawings preferred embodiment of the utility model.As shown in Figure 1, the utility model comprises burner 1, firing chamber 13, oil pipe, housing, base 12 and anti-riot door 11, oil pipe is by annular revetment pipe 9, inner coil pipe 5 and outer coil pipe 4 are connected in turn, inner coil pipe 5 and be welded in several pins 7 of inner coil pipe inboard and fireproof coating 6 is formed throat less chambers 13, pin can strengthen heat transfer, can also cool off fireproof coating, can prolong chamber wall working life, barrel-type casing by sidewall 10 with before, bonnet 2 usefulness bolts link to each other and form, be provided with thermal insulation layer 3 in the sidewall, before, the interior fireproof coating that outwards is equipped with successively from the lining of bonnet, thermal insulation layer and high temperature resistant heat insulation layer, the lateral part of outer coil pipe 4 is embedded in the thermal insulation layer 3 on the sidewall of the furnace body, annular space between inner coil pipe and the outer coil pipe is a flue 14, revetment pipe 9 is put in the steering chamber of combustor tail, and as shown in Figure 2, annular flue top is provided with the dividing plate 15 of two symmetries.

The utility model working procedure is as follows: crude oil enters from import; high-temperature flue gas heat exchange through revetment pipe and steering chamber; rear cover body is protected; flow into then in the inner coil pipe and combustion chamber high temperature section radiation heat transfer and smoke convection heat exchange; flow at last in the outer coil pipe and carry out middle low temperature convection heat exchange with flue gas, flue gas is introduced into the flue of the lower partition through steering chamber; turn back then after top flue and crude oil carries out convection heat exchange, discharge from chimney 8.This inside and outside coil arrangement seemingly resembles the major thread pipe, and flue gas washes away in intermediate lateral, increases to scratch, good effect of heat exchange is divided into two return with dividing plate with the convective region in addition, has increased cigarette speed, heat-transfer coefficient is very high, has reduced a large amount of heating surfaces, makes temperature of exhaust fume drop to 160 ℃.

Claims

1, a kind of crude oil heater, comprise housing, burner, firing chamber and oil pipe, it is characterized in that: said oil pipe is connected in turn by revetment pipe, inner coil pipe and outer coil pipe, inner coil pipe and several pins and the fireproof coating that are welded on the inner coil pipe are formed throat less chamber, be provided with thermal insulation layer in the barrel-type casing, the outer then portion of outer coil pipe is embedded in the thermal insulation layer on the sidewall of the furnace body, and annular flue top is provided with two dividing plates of symmetry.
