Technical Field

The utility model relates to the field of production and processing equipment, in particular to condensation collection equipment.

Background

The existing condensation collecting equipment is mostly adopted to condense steam in a vacuum environment and collect condensed water, because a condensing device of the condensation collecting equipment cannot be completely sealed with a buffer tank, external gas can enter the buffer tank after the condensation collecting equipment is stopped for a certain time, so when the condensation collecting equipment is started again, the condensed water generated by the condensing device collides with the gas in the buffer tank, the condensed water cannot smoothly enter the buffer tank, and therefore, a vacuum pump is also commonly adopted to extract the gas in the buffer tank; however, the air suction speed of the vacuum pump is constant, and when the condensed water is generated too little, the constant air suction will cause the buffer tank to excessively suck air, so that the air pressure of the buffer tank is too small, and the water flows back to the condensing device, thereby affecting the normal use of the condensing and collecting device.

Detailed Description

As shown in fig. 1, a condensation collection apparatus includes a condensing device 10, a buffer tank 20, a control valve 40, and a vacuum pump 50, the condensing device 10 for condensing steam into condensed water; the buffer tank 20 is hermetically communicated with the output port; the inlet end of the vacuum pump 50 is in sealed communication with the buffer tank 20 through the control valve 40.

During the use, steam gets into condensing equipment 10 and converts the comdenstion water into, can improve the pumping speed of vacuum pump 50 to the cushion valve through the aperture of big control valve 40 earlier to can take out the air in buffer tank 20 fast and guarantee to intake smoothly, and when the volume of condensation aquatic products becomes little, then the accessible reduces the pumping speed of vacuum pump 50 by adjusting the aperture of little control valve 40, so that pressure balance between condensing equipment 10 and the buffer tank 20, avoid the condensate water refluence in the buffer tank 20, thereby ensure this condensation collecting device's normal use.

In particular, the condensation device 10 comprises a heat exchanger with an output.

Furthermore, the output port is communicated with the upper end of the buffer tank 20, and the opposite output port is communicated with the lower end of the buffer tank 20, so that the possibility of backflow of condensed water caused by the self weight of the condensed water can be reduced.

Furthermore, the output port is communicated with the buffer tank 20 through a pipeline 80, so that the installation is convenient.

The condensation collecting device also comprises a collecting device 30, wherein the collecting device 30 comprises a drainage pump 31 and a collecting tank 32, the volume of the collecting tank 32 is larger than that of the buffer tank 20, the collecting tank 32 can store more condensed water, and the internal pressure of the buffer tank 20 can be adjusted more easily through the vacuum pump 50 when the volume of the buffer tank 20 is small; the input end of the drainage pump 31 is in sealed communication with the buffer tank 20, and the output end of the drainage pump 31 is in sealed communication with the collection tank 32, so that the drainage pump 31 provides power for water movement to ensure that water can smoothly enter the collection tank 32.

Further, the input of drain pump 31 communicates with the lower extreme of buffer tank 20, and at this moment, the dead weight of water can make water more easily flow to drain pump 31 direction, and drain pump 31 is more comprehensive to drawing water in buffer tank 20.

Specifically, the output end of the drain pump 31 communicates with the upper end of the collection tank 32, reducing the possibility of water flowing backward under its own weight.
