Atmospheric superconductive heating furnace

Abstract

The invention relates to an atmospheric superconductive heating furnace for heating oil, gas, water and mixture medium thereof. The atmospheric superconductive heating furnace mainly comprises a housing, a sealing head, a superconductive sleeve, a serpentine coil, a sealing support graining board, an oil-gas entrance, a burner, a fire tube, an anti-explosion port, a chimney, a smoke box, a support seat, a breath type watersealed liquid level indicator, a sewage outfall and a cleaning port. The bottom of the inner cavity of the housing is provided with the fire tube and the anti-explosion port; the fire tube is connected with the chimney through the wet type smoke box which is arranged on the top of a water chamber cavity; the cleaning port penetrates through the sealing head to be communicated with the smoke box; the lower part of the inner cavity of the housing is provided with a radiative convection chamber, and the upper part is provided with a heat exchanger; two ends of the water chamber cavity are communicated to each other through the heat exchanger; and the breath type watersealed liquid level indicator is communicated with the water chamber cavity to keep the heating furnace in the atmospheric pressure. The invention has the advantages that a water jacket structure is replaced by a sleeve structure, the pressure-resistant capacity of the furnace is improved by over ten times than a water-jacket type heating furnace; in order to prevent explosion of residual gas, pressure bearing is changed into atmospheric pressure, so that the heating furnace does not need a pressure container; and heating furnace with low pressure and high temperature reduces energy consumption, is safe and improves the thermal efficiency.

Description

1. Technical field: [0001] The invention relates to a special heating furnace for oil fields, in particular to an atmospheric superconducting heating furnace for heating oil, gas, water and their mixed media. 2. Background technology: [0002] At present, the water jacket heating furnaces and vacuum superconducting heating furnaces used in the development of my country's oilfields are designed and managed according to pressure vessel standards, with many safety accessories, troublesome management, registration and inspection, high cost and great safety hazards; normal pressure water jackets Although the procedure of the furnace is simple and safe, the loss of the media medium is large, the addition is frequent, and the temperature difference is small (water temperature is less than 100 degrees Celsius), and the thermal efficiency is low, so it is difficult to meet the actual production needs; although the tube furnace has high thermal efficiency, it is easy to coke and burn.
