Fully submerged electrode steam boiler with circulating device

Abstract

The application discloses a fully submerged electrode steam boiler with a circulating device. The steam boiler comprises a boiler shell, a partition plate and a heating device; the partition plate isarranged in the boiler shell and divides the boiler shell into a lower half cavity and an upper half cavity which are independent and communicates with each other; the heating device is arranged in the upper half cavity; the lower half cavity is provided with a water replenishing port, and the upper half cavity is provided with a first outlet. The steam boiler also comprises a circulating water inlet, a circulating water outlet and a circulating power device; the circulating water inlet is arranged on the lower half cavity; the circulating water outlet is arranged on the upper half cavity; thecirculating power device is respectively connected with the circulating water inlet and the circulating water outlet; and the circulating power device is used for conveying the water in the upper half cavity to the lower half cavity.

Description

technical field [0001] The invention relates to the field of electric boiler equipment, in particular to a fully submerged electrode steam boiler with a circulation device. Background technique [0002] Patent CN2018201319785 provides an electrode heating boiler. This electrode heating boiler divides the pot shell into two parts through the partition function. After dividing the pot shell into two parts, a problem is caused, that is, the space in the pot shell is divided by the partition plate. There are two upper and lower chambers, and the water temperature in the upper chamber is higher than that in the lower chamber. Due to the difference in water temperature between the upper and lower chambers, there is a temperature difference between the upper and lower parts of the pot shell, and during the working process In the process, the temperature difference between the upper and lower chambers will become larger and larger, and there will be a large temperature difference in...

[0002] Patent CN2018201319785 provides an electrode heating boiler. This electrode heating boiler divides the pot shell into two parts through the partition function. After dividing the pot shell into two parts, a problem is caused, that is, the space in the pot shell is divided by the partition plate. There are two upper and lower chambers, and the water temperature in the upper chamber is higher than that in the lower chamber. Due to the difference in water temperature between the upper and lower chambers, there is a temperature difference between the upper and lower parts of the pot shell, and during the working process In the process, the temperature difference between the upper and lower chambers will become larger and larger, and there will be a large temperature difference in the pot shell, which will reduce the service life of the pot shell on the one hand, and will easily cause dangerous accidents
