Energy-saving heating furnace

Abstract

The invention discloses an energy-saving heating furnace. The problems that the efficiency of a heating furnace is reduced due to the fact that an existing oil field heating furnace fire tube and smoke tube are short in length and prone to scaling, and the heating furnace cannot work normally caused by backflow of water in smoke are mainly solved. The energy-saving heating furnace is characterizedin that a smoke pipe (9) and fire pipes (6) are built in a shell (8), a liquid inlet pipe (1) is connected with a plurality of liquid inlet branch pipes (5), and the liquid inlet branch pipes (5) arearranged on the upper parts of the smoke pipe (9) and any one of the fire pipes (6); and a water storage tank (19) is fixed to the top of the shell (8), the water storage tank (19) is connected witha water storage tank water inlet pipe and a water storage tank water outlet pipe (18) correspondingly, wherein the water storage tank water inlet pipe is connected with a chimney drainage pipe (13), and the water storage tank water outlet pipe (18) is in communication with the interior of the shell (8). According to the energy-saving heating furnace, the fire pipes and the smoke pipe are lengthened, scale on the outer wall of the fire pipes and the smoke pipe is reduced, the heating efficiency is improved, the water in the smoke is recovered, and the situation that the heating furnace is damaged because the water flows into the fire pipes is avoided.

Description

technical field [0001] The invention relates to the field of oil fields, in particular to an energy-saving heating furnace used in oil fields. Background technique [0002] In the oil field production process, in order to ensure normal production, it is necessary to use a heating furnace to heat the oil and water. The water on the oil field is recycled and contains impurities, which can easily cause serious fouling on the outer walls of the fire pipe and smoke pipe. At the same time, the original two-in-one heating furnace is equipped with an oil recovery system, which occupies most of the space of the heating furnace, resulting in a relatively short length of the fire pipe and smoke pipe, which reduces the thermal efficiency. As the water content of the oil field continues to rise , The oil collection system is no longer necessary. In addition, when the temperature of the inner cavity of the chimney is lower than 100°C, the water contained in the flue gas will flow to the...

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing oilfield heating furnaces, such as the short length of the fire tube and the smoke pipe, the easy fouling of the heating furnace, the reduced efficiency of the heating furnace, and the reflux of water in the flue gas, which makes the heating furnace unable to work normally, the present invention provides an energy-saving heating furnace. Furnace, the energy-saving heating furnace lengthens the fire pipe and smoke pipe, reduces the scaling on the outer wall of the fire pipe and smoke pipe, improves the heating efficiency, recycles the water in the flue gas, and avoids the damage of the heating furnace caused by flowing into the fire pipe
