Description

Technical Field

[0001] The present application relates to the field of steam, and in particular to a steam boosting device. Background Art

[0002] In existing chemical production equipment, the rational use and recovery of steam are key factors in energy conservation and consumption reduction. Steam is also divided into many grades, including high steam, medium steam and low steam. Different working conditions use steam of different grades and qualities. A lot of low-pressure steam is not used reasonably, which will cause energy waste. For example, the low-pressure steam produced by the low-pressure waste heat boiler of the nitric acid unit, the low-transformation waste boiler of the synthetic ammonia unit, the low-steam flash tank of the ammonium nitrate unit, the melamine unit and other equipment is directly vented due to the low pressure of the by-product steam, or directly cooled by a condenser (including but not limited to: water cooler, air cooler, evaporative air cooler, etc.) to discharge the heat to the steam.

[0003] In the current steam boosting process, a separator is needed to achieve vapor-liquid separation of the steam. However, in the use of the current separator, the low-steam pipeline aggregation pipe is directly inserted into the separator tank body, and a filter is set on the top of the tank body to achieve vapor-liquid separation of the steam. In the use of such a separation tank, the low-steam pipeline aggregation pipe supplies the steam to the center of the filter screen, and the separated aqueous solution blocks the mesh of the filter screen, which results in poor vapor-liquid separation effect of the steam boosting device, thereby affecting the use of the steam boosting device.

[0027] Working principle: The present application collects the steam generated inside each steam production device through the low steam pipeline and enters the pipe 1 to add it into the conical steam storage cover 64 set inside the gas-liquid separator 6. The water vapor is supplied to the nozzle 611 through the steam inlet nozzle 69, the exhaust pipe 68 and the steam injection pipe 612. The rotating motor 66 drives the rotating rod 67 to drive the nozzles 611 at the four corners to perform rotating steam injection. Then, the water vapor can be evenly sprayed into the groove at the bottom of the conical filter bucket 613, and enter the filter plate 615 through the ventilation hole 614. The filter plate 615 filters the water vapor. The filtered water vapor is added to the compression tank 7 through the steam outlet 62 and the connecting pipe for air compression and pressure-boosting treatment. The temperature of the compressed water vapor will also increase accordingly. The water vapor is added to the desuperheater 8 through the connecting pipe. The aqueous solution in the steam condensate pipe 9 is added to the liquid spray nozzle 93 through the connecting pipe, so as to achieve cooling treatment of the water vapor in the desuperheater 8. The treated water vapor is added to the interstage separator 10 through the connecting pipe for pressure separation treatment. The separated water vapor is supplied to each low-steam user in turn through the low-steam pipeline collection discharge pipe 13, thereby achieving safe pressure-boosting treatment of the water vapor, which facilitates the use of steam.
