Description
Technical field:
the utility model relates to the field of deaerator equipment, in particular to a rotary film deaerator.
The background technology is as follows:
the boiler feed water contains dissolved gas, and the higher the temperature is, the more easily the dissolved gas reacts with metal, so that pipelines and power equipment are corroded, and the greatest hazard is that the dissolved gas is oxygen. Thus, to ensure long-term safe operation of the thermodynamic system, the dissolved oxygen in the boiler feedwater must be removed. The spiral film deaerator is an important device for removing dissolved oxygen in boiler equipment, and generally comprises a water tank and a deaerating tower arranged above the water tank, wherein the basic principle is thermal deaeration, namely, the higher the temperature of water is, the lower the solubility is for various gases dissolved in water under a certain pressure. In the deoxidization process, external hot steam enters the deoxidizer from a heating steam port, and fully exchanges heat with low-temperature water flowing from top to bottom, so that oxygen dissolved in water is separated out when the water supply is heated to a saturation temperature under corresponding pressure, and is effectively removed. The steam heats the low-temperature water for the first time below the filler layer of the deoxidizing tower, and the homogenized steam heats the low-temperature water for the second time above the filler layer.
However, the rotary film deaerator has the following problems in the actual use process: for a deaerator with a heating steam port arranged at the top of a water tank, such as a YDXM-145/1800145T/H large cyclone membrane deaerator, the pipe orifice at the joint of the deaerating tower and the water tank is thinner, when water at the top of the tower always enters the water tank through the pipe orifice, steam in the water tank is difficult to rise to the top of the deaerating tower, so that the contact time of low-temperature water and hot steam is short, the water temperature is difficult to heat to the saturated temperature under the pressure of the heating steam, and the oxygen in the water is not thoroughly separated; the pressure at the bottom of the water tank is high, rising steam and falling water flow impact cause the water seal of the water tank to act frequently, and the deaerator vibrates.
The utility model comprises the following steps:
the utility model aims to provide a rotary film dust remover which can effectively improve the heat exchange efficiency of steam and water supply and reduce dissolved oxygen in water.
The utility model is implemented by the following technical scheme: the rotary film deaerator comprises a water tank, wherein a deaeration tower is fixedly connected above the water tank, a heating steam port is formed in the top of the water tank, a filler layer is arranged in the deaeration tower, a heating steam pipeline is arranged in the water tank, an inlet of the heating steam pipeline is communicated with the heating steam port, and an outlet of the heating steam pipeline penetrates through the top of the water tank and is arranged below the filler layer; the heating steam pipeline is characterized in that a bracket is fixedly connected above an outlet of the heating steam pipeline, and a baffle is fixedly arranged on the bracket.
Preferably, the baffle is a circular baffle.
Preferably, the distance between the baffle plate and the outlet of the heating steam pipeline is 150mm.
The utility model has the advantages that: the external hot steam directly enters the deoxidizing tower from the heating steam pipeline, and the low-temperature water is uniformly dispersed and falls down after passing through the filler layer, so that the heat exchange with rising steam can be fast carried out, the enough contact time between the low-temperature water and the steam is ensured, and the heat exchange efficiency is improved; a round baffle plate is arranged below the packing layer to prevent the steam from directly blowing the packing and enable the steam to uniformly spread around, so that heat exchange is better carried out; the pressure at the bottom of the water tank is effectively reduced, the water seal function is ensured to be perfect, and the vibration of the deaerator is reduced.

The specific embodiment is as follows:
the following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1:
the rotary film deaerator shown in fig. 1 comprises a water tank 1, wherein a deaerating tower 2 is fixedly connected above the water tank 1, a heating steam port 1.1 is arranged at the top of the water tank 1, and a packing layer 2.1 is arranged inside the deaerating tower 2.
A heating steam pipeline 1.2 is arranged in the water tank 1, an inlet of the heating steam pipeline 1.2 is communicated with the heating steam port 1.1, and an outlet of the heating steam pipeline 1.2 passes through the top of the water tank 1 and is arranged below the packing layer 2.1.
