    摘要： The present invention relates to a method for efficiently recovering energy from off-gas with high temperatures and high pressures released from the oxidation reactor of aromatic compounds such as xylene, pseudocumene, durene and the like. More particularly, the present invention relates to a method for energy recovery from oxidation reactor off-gas, which comprises subjecting off-gas with high temperature and high pressure from an oxidation reactor to heat exchange with cooling water to cool the off-gas, subjecting the cooled off-gas to direct counter-flow contact with the water heated by said heat exchange to obtain a mixture of off-gas and steam, and cooled water, circulating the cooled water for reuse as said cooling water for said high temperature and high pressure off-gas, and sending the mixture of off-gas and steam to an expander to recover energy therefrom. According to the present invention, the energy recovered from off-gas increases by an amount equivalent to the amount of steam saturating in and accompanying the off-gas.

    摘要： A folding and lock mechanism for a pushcart includes a bracket pivotally mounted at its proximal end on a rear face of a rear leg intermediate opposite ends of the rear leg so that the bracket can be pivotally moved along the rear face of the rear leg between a generally upstanding position and a lower position. A retainer plate is formed on a lower end of a handle grip, and has a bifurcated end of a generally L-shape or inverted Y-shape defined by a pair of engaging arms. The retainer plate is pivotally connected to the distal end of the bracket at that portion of the retainer plate where the pair of engaging arms merge together. One of the two engaging arms is fitted in a groove formed in the distal end of the bracket to maintain the assembled condition of the pushcart whereas the other engaging arm is fitted in the groove to maintain the folded condition of the pushcart. A tubular stopper is fitted on the distal end portion of the bracket and is slidingly movable along the bracket. The stopper is able to fit on and retain either of the pair of engaging arms which is selectively fitted in the distal end of the bracket.
