Energy-saving and environment-friendly thermal deaerator

Abstract

The invention discloses an energy-saving and environment-friendly thermal deaerator. The energy-saving and environment-friendly thermal deaerator comprises a deaerator body. A deoxygenation head is mounted at the top end of the deaerator body. A recovery pipe is mounted at the top end of the deoxygenation head. A water storage tank is mounted on one side of the deaerator body. A second separator is mounted at the top end of the water storage tank. The energy-saving and environment-friendly thermal deaerator is provided with the recovery pipe, a preheater, a condensate water return pipe, a condensing agent circulating pipe, a condenser and a condensing agent discharge pipe. Primary waste steam and secondary waste steam discharged from the interior of the deaerator body are recovered throughthe recover pipe. The recovered waste steam firstly passes through the recover pipe to go into the condenser and is subjected to heat exchange through a condenser pipe in the condenser. After heat exchange, water vapor in the waste steam is condensed into liquid water. Heat in the waste steam is transferred to a condensing agent in the condenser pipe. The condensed liquid water passes through a pressure valve and the condensate water return pipe to be discharged into the water storage tank, and the cyclic utilization of water is realized.

Description

technical field [0001] The invention belongs to the technical field of thermal deaerators, and in particular relates to an energy-saving and environment-friendly thermal deaerator. Background technique [0002] Thermal deaerator is a new type of thermal deaerator, which can remove dissolved oxygen and other gases in the feed water of the thermal system and prevent corrosion of thermal equipment. It is an important equipment to ensure the safe operation of power plants and industrial boilers. Thermal deaerators are used in During use, the condensed water is heated by high-temperature steam. During the gradual heating of the condensed water, the dissolved oxygen and other non-condensable gases in the condensed water gradually escape, and form exhausted steam with water vapor to be discharged. [0003] However, the exhaust steam discharged from the existing thermal deaerator contains a large amount of water vapor and heat, and the direct discharge causes a large amount of waste...
