Abstract

The invention discloses a steam waste heat waste water preheating device. The steam waste heat waste water preheating device comprises a preheating pool, the inner part of the preheating pool is provided with a preheating chamber, the preheating pool is connected with a water pumping pipe in an external manner, one end of the water pumping pipe is equipped with a water suction pump, the other endof the water pumping pipe is equipped with a water outlet pump, the water outlet pump is installed on the position of the inner side wall of the top of the preheating pool, the end part of the other end of the water pumping pipe is of a curved shape; the bottom of the preheating pool is equipped with a drainage pump; the inner part of the preheating pool is equipped with a steam preheating mechanism, the steam preheating mechanism comprises a preheating pipe, the preheating pipe is of a spiral shape, the upper end of the preheating pipe is equipped with a steam inlet pipe, the end part of thesteam inlet pipe is equipped with a steam pump, the upper side of the end part of the steam inlet pipe is equipped with an air inlet pipe, an air pump is arranged at the top end of the air inlet pipe,and a control switch is arranged between the air pump and the top end of the air inlet pipe. According to the steam waste heat waste water preheating device, the spiral- shaped preheating pipe is provided, so that the area of steam heating is greatly improved; and the efficiency of performing pre heating of the waste water in the preheating pool is greatly improved through the spiral preheating pipe.

Description

technical field [0001] The invention relates to a preheating device, in particular to a steam waste heat waste water preheating device. Background technique [0002] Vortex pump is a kind of vane pump. The vortex pump is mainly composed of impeller, pump body and pump cover. The impeller is a disc, and the blades on the circumference are evenly arranged radially. An annular flow channel is formed between the pump body and the impeller, and the suction port and the discharge port are located on the outer circumference of the impeller. There is a partition between the suction port and the discharge port, thereby isolating the suction port and the discharge port. The liquid in the vortex pump is divided into two parts: the liquid between the blades and the liquid in the flow channel. When the impeller rotates, under the action of centrifugal force, the peripheral velocity of the liquid in the impeller is greater than the peripheral velocity of the liquid in the flow channel...

AI Technical Summary

Problems solved by technology

At the same time, it also causes a large impact loss, so the efficiency of the vortex pump is relatively low

The existing steam pump is inconvenient to heat the waste water by using steam waste heat, and the efficiency of preheating the waste water is low
