Technical Field
The invention relates to a device for recovering steam, in particular to a self-suction type fixed-discharge white-fading device with a fin grid.
Background
When the power station boiler normally operates, hot water leaked in a valve, drainage before soot blowing, continuous blowdown and the like are discharged into a fixed-discharge flash tank, two parts of media are formed after flash tank expansion, one part of the media is condensed water, the other part of the media is saturated steam with the temperature of 90-100 ℃, the condensed water is recycled, the saturated steam is discharged into the atmosphere along with an exhaust pipeline of the flash tank, and the steam discharged into the atmosphere wastes and pollutes the air.
The invention can realize natural circulation of air in the condensing pipeline and self-adapt to the steam flow, thereby replacing the spray device and saving equipment cost, energy and water.
The main difference between the invention and the Lele's utility model patent (No. CN 203687001) "device for recovering the steam in the steam discharge cylinder of the fixed-row flash tank" is that the fins on the outer wall of the condensing pipe are arranged along the axial direction of the pipe and connected to the exhaust pipe, and the inner wall of the condensing pipe is provided with a plurality of layers of grids, thereby increasing the heat exchange area and the heat exchange time; secondly, a plurality of air inlets communicated with the condensing pipeline are arranged on the side wall of the steam exhaust pipeline, so that the air flow is increased, and the heat exchange efficiency is improved; and the condensing pipeline and the grating are made of aluminum alloy, and have higher heat transfer coefficient than stainless steel, so that the heat exchange efficiency is improved.
Disclosure of Invention
The invention aims to provide a self-suction type fixed-row white-fading device with a finned grid.
The invention aims to implement the following technical scheme, and the self-suction type fixed-discharge white-fading device with the finned grating comprises a fixed-discharge flash tank, a steam discharge pipeline, a condensed water discharge pipeline and an exhaust pipeline, wherein a section of condensation pipeline is arranged in the exhaust pipeline, each section of fins are uniformly distributed on the outer wall of the condensation pipeline, a plurality of layers of gratings are uniformly distributed on the length of the inner wall of the condensation pipeline, a plurality of air inlets corresponding to the condensation pipeline are arranged on the side wall of the exhaust pipeline, one end of the condensation pipeline is communicated with the air inlets, and the other end of the condensation pipeline is an air outlet and is directly communicated with the atmosphere.
For convenient installation, be equipped with one section condensation duct in the steam extraction section of thick bamboo, every section fin evenly distributed on the condensation duct outer wall, every section the length of fin is 10 meters, and the interval is 1 meter.
In order to increase the heat exchange area, fins are fully distributed on the outer wall of the condensation pipeline.
In order to increase the heat exchange area, increase the cold air circulation resistance and prolong the heat exchange time, the inner wall of the condensation pipeline is provided with a plurality of layers of grids.
In order to prevent the long-term adsorption of condensed water to cause corrosion and prolong the service life of the condensation pipeline, the condensation pipeline is an aluminum alloy pipeline.
The middle part of the condensation pipeline is fixedly connected with the inner wall of the exhaust pipeline through a connecting piece so as to reduce the tensile stress at the joint of the condensation pipeline and the exhaust cylinder and prolong the service life of the joint.
The invention utilizes the characteristic that hot air flows upwards, because the inside of the exhaust pipeline is saturated steam, the temperature can reach 90-100 ℃, a section of condensation pipeline is arranged in the exhaust steam cylinder, the temperature of the air in the condensation pipeline is close to the saturated steam temperature of the exhaust pipeline through heat exchange, the steam heats the air in the condensation pipeline, because the added upper and lower pipe orifices of the condensation pipeline are communicated with the outside atmosphere, the air flows upwards along with the rise of the temperature of the air in the condensation pipeline from bottom to top, so that a bottom-to-top air flow is formed in the added condensation pipeline, namely, the outside cold air is sucked from the lower inlet and discharged from the upper inlet, a natural circulation is formed in the condensation pipeline, and the purpose of reducing the temperature of the exhaust pipeline is achieved by utilizing the circulation of the outside cold air. When the temperature of the exhaust pipeline is reduced, saturated steam is condensed into water, condensed water is condensed outside the condensing pipeline (inside the exhaust pipeline), and then flows back to the fixed discharge flash tank, so that the purpose of recovering and discharging steam is achieved. The added condensation pipeline is made of aluminum alloy materials, so that corrosion caused by long-term adsorption of condensed water is prevented. The fins are arranged on the outer wall of the condensation pipeline, and the grids are arranged on the inner wall of the condensation pipeline, so that the heat exchange area is increased, and the service life is prolonged.
The invention has the advantages that the self-absorption of the steam can be realized without external equipment and energy, the steam flow is self-adaptive, and the defect that the cooling water flow of the spray type white elimination device is difficult to determine is avoided; a large amount of water resources can be recovered, and the resource waste is reduced; simple structure and ingenious design concept.
