Problems solved by technology

The center tube, support screen and shell of the existing internal heating type natural gas molecular sieve dehydration device are welded together. Due to the alternating change of molecular sieve adsorption and regeneration, the thermal expansion and contraction effect of the center tube will affect the support screen and / or shell. The body produces alternating stress, which is easy to damage the internal heating type natural gas molecular sieve dehydration device, thereby reducing the service life of the internal heating type natural gas molecular sieve dehydration device

Abstract

The invention discloses a multifunctional molecular sieve dehydrating tower. A first support screen plate and a second support screen plate are arranged in a shell; mounting through holes are formed in the first support screen plate and the second support screen plate; threaded connection sleeves are arranged on the upper plate surfaces of the first support screen plate and the second support screen plate; mounting sleeves are in threaded connection with the threaded connection sleeves to be mounted on the first support screen plate and the second support screen plate; a center sleeve is inserted into the shell from the top of the shell and extends into the mounting sleeves and reaches a cavity between the lower plate surface of the first support screen plate and the inner bottom wall of the shell; the outer wall of the center sleeve is in seal connection with the inner walls of the mounting sleeves through a rubber seal ring; an adjusting sleeve is sleeved on the axial upper section of the center sleeve through threaded fit; an electric heating pipe of an electric heater at the top end of the adjusting sleeve passes through the top end of the adjusting sleeve and extends into thecenter sleeve in the shell. The multifunctional molecular sieve dehydrating tower disclosed by the invention has the advantage that the damage of the support screen plates and the shell caused by theheat-expansion and cold-contraction effect of the electric heating pipe can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of oil and gas treatment, in particular to a multifunctional molecular sieve dehydration tower. Background technique [0002] Since the existence of liquid water in natural gas will seriously affect the safety of automobiles and filling stations, it is necessary to dehydrate natural gas so that the dehydrated natural gas meets safety standards. The center tube, support screen and shell of the existing internal heating type natural gas molecular sieve dehydration device are welded together. Due to the alternating change of molecular sieve adsorption and regeneration, the thermal expansion and contraction effect of the center tube will affect the support screen and / or shell. The body produces alternating stress, which is easy to damage the internal heating type natural gas molecular sieve dehydration device, thereby reducing the service life of the internal heating type natural gas molecular sieve dehydration ...
