Heated air circulation heating device of oil storage vessel

Abstract

A hot air circulation heating device for an oil storage tank, characterized in that the coal-fired hot air heating furnace is set as a rectangle, and consists of a combustion chamber, an ash storage chamber, a partition type furnace, a hot air outlet, an air return port, an air supply port, a smoke exhaust pipe and a regulating valve Composition, the furnace is set to form a labyrinth exhaust gas structure with partitions, the combustion chamber cavity is larger than the labyrinth smoke exhaust chamber, the lower part of the front side is provided with a furnace door, and a furnace grate and a furnace grate are arranged between the lower part of the furnace door and the labyrinth partition. The lower part is set as the ash storage room, the entrance of the labyrinth smoke exhaust structure is set up and down, and finally discharged into the furnace body from the upper part of the last labyrinth; the hot air outlet is set on the top of the furnace body, connected with the induced draft fan with a hot air pipe, A smoke exhaust pipe is provided on the air duct, and a regulating valve is provided on the smoke exhaust pipe; an air supply port is provided on the side of the air outlet, and the connection with the air supply pipe is controlled by a regulating valve.

Description

1. Technical field [0001] The invention relates to a crude oil heating device for a single well pulling oil storage tank, in particular to a hot air circulation heating device for an oil storage tank. 2. Background technology [0002] At present, oil storage tanks are heated for single wells in oil fields, some are heated by hot water circulation, some are heated by superconducting liquid circulation, the heating furnace and oil storage tank are separated, and some are integrated, most of which are heated by natural gas or crude oil in the well. This heating method mainly has the following problems: 1. The natural gas produced by a single well is unstable, and it cannot meet the heating needs of the oil storage tank. 2. The crude oil produced by a single well has high water content or high viscosity, and the furnace combustion is unstable. The furnace is often extinguished and the fuel pipe is often blocked, so the normal operation of the furnace cannot be guaranteed. 3. Th...

AI Technical Summary

Problems solved by technology

This heating method mainly has the following problems: 1. The natural gas produced by a single well is unstable, and it cannot meet the heating needs of the oil storage tank from time to time.

2. The crude oil produced by a single well has high water content or high viscosity, and the furnace combustion is unstable. The furnace is often extinguished and the fuel pipe is often blocked, so the normal operation of the furnace cannot be guaranteed.

3. The temperature of the heat medium rises slowly, and the heat transfer is slow. The temperature of the crude oil in the oil storage tank cannot rise by one degree after heating for one day. It often happens that the oil truck comes and cannot put in the oil, and returns empty, causing the oil storage tank to be full and close the well, which is serious. Affect the normal production of oil wells
