VERTICAL PIPE FOR ELECTRICALLY MELTING A FROZEN UREA SOLUTION USING A FLEXIBLE HEATING MEMBER, CAPABLE OF RAPIDLY MELTING THE FROZEN UREA SOLUTION WITHOUT OPERATING AN ENGINE

摘要

PURPOSE: A vertical pipe for electrically melting a frozen urea solution using a flexible heating member is provided to rapidly melt the frozen urea solution by independently controlling temperature by a temperature control unit.;CONSTITUTION: A vertical pipe(50) for electrically melting a frozen urea solution comprises flexible heating members(60), a filler member, a urea solution suction pipe, and a urea solution return pipe. The flexible heating members are arranged in a space between an outer pipe(50a) and an inner pipe(50b) along the length of the vertical pipe at constant intervals. The flexible heating member is filled with the filler members. The urea solution return pipe is shorter than the urea solution suction pipe. The urea solution return pipe and the urea solution suction pipe are inserted into the inner pipe.;COPYRIGHT KIPO 2013
