Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as Figure 1-6 As shown, the present invention includes a housing 4 and an insulating layer 3 on the inner wall of the housing. A water-water heat exchanger 1 is installed on the top surface of the housing. The left side of the housing is provided with a combustion area, the right side is provided with a convection area, and the outer wall of the housing is installed Chimney 5; the combustion zone includes a fuel ignition nozzle and a spiral square membrane wall. The spiral square membrane wall is composed of a radiant tube bundle 7, an elbow 8 and a fin 9. 11. For φ89×13 or φ60×9 tube bundles, one end of the first radiant tube bundle is welded with a 90° elbow, and the o...

Abstract

The invention discloses a movable type oil field steam generator with a spiral square film type wall. The movable type oil field steam generator comprises a shell body and a shell body inner wall heat preservation layer, a water-water heat exchanger is arranged on the top face of the shell body, a combustion area is arranged on the left side inside the shell body, a convection area is arranged on the right side inside the shell body, and a chimney is arranged on the outer wall of the shell body. The combustion area comprises a fuel ignition nozzle and the spiral square film type wall, the convection area is composed of a light pipe row, a finned pipe row and an elbow, the water-water heat exchanger is composed of an inner pipe and an outer pipe, the water outlet end of the outer pipe of the water-water heat exchanger is connected with the water inlet end of a convection finned pipe, the water inlet end of the inner pipe of the water-water heat exchanger is connected with the water outlet end of a convection light pipe, and the water outlet end of the inner pipe of the water-water heat exchanger is connected with the right water inlet end of a square spiral pipe. The elbow heated face of an original oil field steam generator convection pipe bundle is fully utilized, the convection area is increased by 10 percent, and therefore manufacturing cost is lowered.

Description

technical field [0001] The invention relates to the field of thermal recovery and development of oilfield heavy oil steam, and more specifically relates to a mobile spiral square membrane wall oilfield steam generator. Background technique [0002] Since most domestic oil fields currently use traditional steam generators, traditional steam generators are mainly divided into radiation section, transition section, convection section, water-water heat exchanger, chimney and other parts. The radiant section is mainly used as a fuel combustion chamber. The radiant heat energy released by combustion is absorbed by the horizontal reciprocating furnace tube in the radiant section. The flue gas generated is stably diverted in the transition section and then enters the convection section. The convection section mainly uses light tubes + fins The convection heating surface arranged by the tubes, through the flue gas and the water in the convection section furnace tubes, countercurrent ...
