Description
Technical Field
The utility model relates to a general steam production equipment, especially a boiler tail gas energy recuperation utilizes device.
Background
The steam boiler is a kind of plant public equipment which produces steam by heating water to boil through the heat energy generated by burning gas. The water source needs to remove organic and inorganic substances, and because the dissolved oxygen in the water corrodes the boiler, the dissolved oxygen in the water promotes the electrochemical corrosion reaction, which causes severe oxygen corrosion of the boiler system. Therefore, the boiler feed water is subjected to an oxygen removal process prior to entering the boiler. The conventional oxygen removal treatment method generally adopts a physical method, namely thermal oxygen removal, and water supply is heated by steam to remove dissolved oxygen, so that a part of steam is consumed. The temperature of the tail gas discharged by the boiler is as high as about 130-.
Disclosure of Invention
To the above situation, for solving the defects of the prior art, the utility model aims to provide a boiler tail gas energy recovery and utilization device, which can effectively solve the problems of boiler tail gas energy recovery and utilization and gas consumption.
The technical scheme who solves is, including boiler, flue and chimney, the boiler flue gas export is linked together through flue and chimney, is provided with even cavity as an organic whole on the chimney, is equipped with the heat exchanger in the cavity, and heat exchanger one end is linked together with the inlet channel, and the other end is linked together through outlet conduit and heating power oxygen-eliminating device water inlet, and heating power oxygen-eliminating device delivery port is linked together through second outlet conduit and force (forcing) pump water inlet, and the force (forcing) pump delivery port is linked together with the boiler water inlet.
The utility model discloses novel structure is reasonable, can effectively carry out recycle to boiler tail gas energy, has practiced thrift gas consumption greatly, has reduced environmental pollution, has saved manufacturing cost, is the innovation on the boiler tail gas energy recuperation device.
