Abstract

The invention discloses a low-heat-loss type deaerator for a power plant boiler. The low-heat-loss type deaerator comprises a deaerator body, the deaerator body internally comprises a water storage tank body, the outer side of the water storage tank body is fixedly connected with an air cylinder, the movable end of the air cylinder is fixedly connected with a tank door, and the inner side of the tank door is fixedly connected with a sealing clamping block; the upper end of the gear box is fixedly connected with an air pump, an air outlet of the air pump is fixedly connected with a deflation pipe, a guide groove is formed in the outer wall of the deflation pipe, a guide block is fixedly connected in the sleeving pipe, a spring is fixedly connected in the mounting groove, a positioning clamping button is fixedly connected to the outer side of the spring, and a sealing groove is formed in the connecting pipe fitting. According to the low-heat-loss type deaerator for the power plant boiler, the overall heat preservation effect is improved, rapid heat dissipation of the whole deaerator in the using process is facilitated, the overall heating speed is increased, violent shaking caused bythe excessively large overall temperature difference is reduced, and the overall practicability is improved.

Description

technical field

[0001] The invention relates to the technical field of deaerators, in particular to a low heat loss deaerator used in power plant boilers. Background technique

[0002] The deaeration equipment is mainly composed of the deaeration tower head, the deaeration water tank, the connecting pipe and the external parts. pipe), water spray grate, thermal storage packing liquid vapor network and other components, deaerator equipment removes oxygen and other gases dissolved in feed water, prevents and reduces corrosion of boiler feed water pipes, economizers and other ancillary equipment, deaerator It is one of the key equipment of the boiler and heating system. If the deaerator has poor oxygen removal capacity, it will cause serious losses to the corrosion of the boiler feed water pipe, economizer and other auxiliary equipment, and the economic loss caused will be the cost of the deaerator. Dozens or hundreds of times of that, the Ministry of Electric Power of the Peo...
