Horizontal tank and its raceway processing method for eliminating thermal stress

Abstract

The invention relates to a horizontal tank used for eliminating thermal stress. The horizontal tank comprises a tank body and a supporter arranged at the bottom of the tank body; the supporter comprises a fixed bracket and at least one movable bracket; the fixed bracket is arranged at one end of the tank body and is 1 / 10-1 / 3 to the total length of the tank body; the movable bracket comprises at least one rolling element arranged at the bottom of the tank body, a limiting baffle and a raceway; the limiting baffle is fixedly installed at the bottom of the tank body; a card slot matched with the rolling element and used for clamping the rolling element is arranged in the limiting baffle; the raceway of each movable bracket is arranged in the same horizontal plane; a liquid injector is arranged above the tank body; a vertical liquid injection pipe and a horizontal delivery pipe are arranged on the liquid injector; and the length of the liquid injection pipe is greater than 1.5m. According to the invention, the fixed bracket is matched with the movable bracket, so that the problems of the subfissure of the tank body because of the expansion of the volume of the tank body caused by heat emission during the reaction of chemical raw materials in the tank and the problem of unreliable connection of pipe joints caused by the movement of the tank body when the tank body expands after being heated are solved.

Description

technical field [0001] The invention relates to the technical field of horizontal tanks, in particular to a horizontal tank for eliminating thermal stress and a processing method for its raceway. Background technique [0002] In chemical enterprises, tanks are important equipment, mainly used for storage of chemical raw materials and chemical reaction tanks. Generally, tanks are fixed on the site by a support mechanism set at the bottom. The support mechanism is generally set to 2 according to the size of the tank. -10 support frames, the large horizontal tank is roughly cylindrical with a diameter of 3 meters and a length of 40 meters, but after a period of use, equipment accidents and production accidents often occur in the tank, and the service life is short. There are hidden cracks in the junction of the supporting mechanism, which will lead to cracks over time, and finally cause the leakage of chemical raw materials, leading to accidents.

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to overcome the technical problem that the thermal stress of the large horizontal tank in the prior art is difficult to release, resulting in hidden cracks in the tank body, and to provide a processing method for the horizontal tank and its raceway that eliminates the thermal stress method, effectively releasing the thermal stress of the tank body, solving the problem of hidden cracks in the tank body, prolonging the service life of the tank, and reducing production accidents
