A kind of clearing frost device and clearing frost method

Abstract

The invention discloses an ice and frost removing device and a method for removing ice and frost, comprising a housing, wherein a heating chamber, a guiding chamber and a drying chamber are arranged in sequence in the housing, wherein the heating chamber, the guiding chamber and the drying chamber are connected in sequence, so that the The heating chamber is provided with a heating element and an air supply element, wherein the air supply element is arranged on the side of the heating chamber away from the guide chamber, wherein the heating element is arranged on the side of the heating chamber close to the guide chamber, wherein the heating element and the air supply element The power supply is externally connected through a cable, and a guide element is arranged in the guide chamber, wherein the guide element is used to make the airflow passing through the guide chamber into a spiral airflow, and one end of the drying chamber is provided with an opening, wherein the drying chamber is provided with an opening. The opening of the chamber is used to put the frozen oil pipe head or oil rod screw, wherein the diameter of the opening end of the drying chamber is larger than the outer diameter of the oil pipe head or the oil rod screw.

Description

technical field [0001] The invention belongs to the technical field of oil production pipeline processing, and in particular relates to a defrost removing device and a defrosting method. Background technique [0002] In the maintenance and repair process of underground oil mining operations, due to the low temperature in the severe winter, the oil pipe rods placed on the ground must be cleaned from the boiler car before entering the well, and the thread will freeze after the wax removal; When the gas condenses in the casing, condensate oil is produced, and water is brought out at the same time, so that the casing head of the test well freezes, causing the casing to be blocked by ice during logging, and logging cannot be performed. [0003] The current routine deicing and defrosting practices are: [0004] It is time-consuming and laborious, and the hardness of the frost is high, and it is difficult to brush it off with a wire brush. Long-term use of a wire brush to clean t...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of deicing device and deicing method, have overcome 1 in the prior art: use steel wire brush to scrub oil rod screw thread, both time-consuming and laborious, moreover frost hardness is relatively high. High, it is difficult to brush it off with a steel wire; 2: Using a wire brush to scrub the oil rod thread, may damage the surface of the oil rod thread and damage the device; 3: Using steel brazing is time-consuming and laborious, and it is easy to damage the surface of the casing head; 4 : Pouring boiled water will remain on the surface of the casing head, and it will freeze again soon at low temperature, etc.
