A device for recovering steam and water from the tail of a wood-based panel hot press machine

Abstract

The invention relates to the field of heat presses, in particular to a device for recovering steam and water from the tail of a wood-based panel heat press, including a wood-based heat press, a steam generator, and a first liquid storage tank. The wood-based heat press includes a steam inlet and an exhaust steam The exhaust port, the steam inlet is connected to the steam outlet of the steam generator, the tail steam exhaust port is connected to the first liquid storage tank, a temperature control valve is arranged between the steam inlet and the steam generator, and the first liquid storage tank The second liquid storage tank is connected with the pressure solenoid valve between the first liquid storage tank and the second liquid storage tank. The second liquid storage tank is connected with the water inlet end of the water pump, and the water outlet end of the water pump is connected with the liquid inlet of the steam generator. A pressure switch is set between the second liquid storage tank and the water pump, and the pressure switch controls the start and stop of the water pump; the tail steam recovery device of the wood-based panel hot press described in this scheme can save labor costs, improve the efficiency of heat energy utilization, and reduce the steam generation energy. consumption.

Description

technical field [0001] The invention relates to the field of hot presses, in particular to a device for recovering steam and water from the tail of a wood-based panel hot press. Background technique [0002] The hot press is a machine used to produce plywood and other multi-layer boards, and it is one of the most important equipment in the production of wood-based panels; it has a platform that can move up and down to apply pressure to the board body; the inside of the platform has steam or electric heating device for plate heating. [0003] Because steam heating has better thermal uniformity and thermal energy efficiency, most of the existing wood-based panel hot presses use steam heating, and the wood-based panel hot presses that use steam heating are equipped with steam inlets and exhaust outlets , the steam inlet is connected to a steam generator, such as a boiler, and the tail steam exhaust port is connected to a condensate storage tank, and the condensed water in the ...

AI Technical Summary

Problems solved by technology

[0004] Since the tail steam recovery of the above-mentioned steam-heated wood-based panel heat press is through condensation and manual extraction, the water temperature of the condensed water returned to the steam generator is relatively low, which causes the steam generator to recover the heat of the condensed water. It consumes a lot of energy, and workers need to take care of it and manually start and shut down the water pump during the recycling process, and the labor cost is relatively high.
