Technical field
The utility model relates to a kind of liquid nitrogen vaporization device, belongs to the liquid nitrogen pump apparatus field of oil field construction.
Background technology
Direct-fired to the common employing of the mode of high pressure low temperature liquid nitrogen heating, i.e. oil burning boiler heating, but for the higher oil gas well of imflammable gas content, the naked light heating is easily blasted, and has potential safety hazard.Therefore, for using the liquid nitrogen pump equipment availability, need the mode of cancellation naked light heating, to adapt to the requirement of explosion proof of oil gas well at the higher oil gas well of imflammable gas content.
The utility model content
The purpose of this utility model is, a kind of heat reclamation type liquid nitrogen vaporization device is provided, overcoming the naked light heating easily blasts, the defective that has potential safety hazard, utilize the cooling agent of heating to evaporate high-pressure liquid nitrogen, improve the explosion-proof ability of liquid nitrogen pump equipment, use the liquid nitrogen pump equipment availability to adapt at the higher oil gas well of imflammable gas content.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of heat reclamation type liquid nitrogen vaporization device, mainly form by front port, preceding lock screw, preceding straight tube, procapsid, coil pipe, manifold trunk, intermediate support plate, back casing, back straight tube, back lock screw, back coolant water interface tube, rear port, preceding coolant water interface tube; Procapsid and back casing are formed evaporator shell, and inner with the intermediate support plate reinforcement, coolant water interface tube before being provided with on the procapsid is provided with back coolant water interface tube on the back casing; Front port is connected by preceding lock screw, preceding straight tube and manifold trunk are anterior, and rear port passes through the back lock screw, the back straight tube is connected with the manifold trunk rear portion; Coil pipe is positioned at evaporator shell inside, is connected with manifold trunk.
The beneficial effect that the utility model is had compared with the prior art is: (1) does not have naked light, and explosion-proof ability is strong, and job safety coefficient height is particularly useful for using the liquid nitrogen pump equipment availability at the higher oil gas well of imflammable gas content.(2) adopt symmetrical structure, high pressure low temperature liquid nitrogen can enter from the interface of any end, discharges high normal pressure and temperature nitrogen from the other end; Equally, the cooling agent of heating can from liquid nitrogen stream round about the coolant water interface tube of an end enter, return liquid from the other end.(3) adopt many coil pipes, to realize big discharge capacity vaporized nitrogen, the maximum evaporation ability is 11327m
3/ h.(4) all high voltage components all adopt high pressure, low temperature material, and maximum amount is decided operating pressure and reached 103Mpa, allow minimum work liquid nitrogen temperature to be-210 ℃, satisfy the requirement of liquid nitrogen pump equipment availability high pressure, low temperature.(5) simple in structure, connect very easy to usely, be easy to promote.

Fig. 1 is a main pseudosection of the present utility model.
Fig. 2 is the section profile of the utility model coil pipe.
Among the figure: straight tube before the lock screw before the 1-front port, 2-, 3-, 4-procapsid, 5-coil pipe, 6-manifold trunk, 7-intermediate support plate, 8-back casing, straight tube behind the 9-, lock screw behind the 10-, coolant water interface tube behind the 11-, coolant water interface tube before the 12-rear port, 13-.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of heat reclamation type liquid nitrogen vaporization device mainly is made up of front port 1, preceding lock screw 2, preceding straight tube 3, procapsid 4, coil pipe 5, manifold trunk 6, intermediate support plate 7, back casing 8, back straight tube 9, back lock screw 10, back coolant water interface tube 11, rear port 12, preceding coolant water interface tube 13; Procapsid 4 and back casing 8 are formed evaporator shell, and inner with intermediate support plate 7 reinforcements, coolant water interface tube 13 before being provided with on the procapsid 4 is provided with back coolant water interface tube 11 on the back casing 8; Front port 1 is by preceding lock screw 2, preceding straight tube 3 and 6 anterior connections of manifold trunk, and rear port 12 is connected with manifold trunk 6 rear portions by back lock screw 10, back straight tube 9; Coil pipe 5 is positioned at evaporator shell inside, is connected with manifold trunk 6.
The course of work: external high pressure low temperature liquid nitrogen and front port 1 (or rear port 12) are connected, and rear port 12 (or front port 1) connects with external high pressure normal temperature nitrogen outlet; The external coolant import connects with back coolant water interface tube 11 (or preceding coolant water interface tubes 13), and preceding coolant water interface tube 13 (or back coolant water interface tube 11) connects with the external coolant outlet.During work, the cooling agent after the outside heating of supplying with enters from an end coolant water interface tube with certain pressure and flow, returns liquid from the other end.High pressure low temperature liquid nitrogen then enters from the interface that flows to rightabout one end with cooling agent, discharges high normal pressure and temperature nitrogen from the other end.What high pressure low temperature liquid nitrogen was flowed through is coil pipe 5 inner passages, and what cooling agent was flowed through is coil pipe 5 outsides, thereby can carry out sufficient heat exchange at coil pipe 5 places, makes high pressure low temperature liquid nitrogen become high normal pressure and temperature nitrogen and discharges.
