Description

Technical Field

[0001] The utility model relates to the technical field of condensation liquid film demisting, in particular to an upgraded and improved structure for condensation liquid film demisting. Background Art

[0002] Condensate liquid film demister, also known as condensate wet film dust removal demister, is a highly efficient dust removal and mist removal structure, widely used in flue gas treatment systems in the power, chemical, metallurgy, food, medicine and other industries.

[0003] A condensate film demister is used to remove dust from the flue gas, so that the flue gas meets the national ultra-low emission standards. However, the existing condensate film demister has a complex structure, high manufacturing and installation requirements, certain temperature requirements, and requires circulating cooling water for cooling. When the dust in the flue gas is sticky, the equipment surface needs to be flushed. Utility Model Content

[0004] The utility model mainly provides an upgraded and improved structure for condensate liquid film demisting, which can enable flue gas to meet the national ultra-low emission standards.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a condensation liquid film demisting upgraded and improved structure, including a condensation liquid film demisting device body, a first ridge-type demisting device is arranged inside the condensation liquid film demisting device body, a flat-plate condensation dust collector is connected directly above the first ridge-type demisting device, a second ridge-type demisting device is connected directly above the flat-plate condensation dust collector, a cleaning water pipe is connected to the surface of the flat-plate condensation dust collector, a filter assembly is connected to the upper end of the cleaning water pipe, and a hot water outlet is connected to the lower end of the cleaning water pipe.

[0006] Preferably, the first ridge-type demister is of the same model as the second ridge-type demister. The ridge-type demister effectively captures liquid droplets carried in the flue gas through its unique multi-fold structure of corrugated plates. When mist-laden gas flows through the demister, the inertial impact of the gas causes the mist to collide with the corrugated plates. When the agglomerated droplets become large enough that their own gravity exceeds the combined force of the gas's upward force and the liquid's surface tension, the droplets are separated from the corrugated plate surface. This successfully separates and collects the majority of the droplets in the flue gas, thereby reducing the water content in the flue gas.

[0007] Preferably, the outer dimensions of the condensate film demister body are 3600mm×22500mm, and the working pressure of the condensate film demister body is 6.0KPa. Under the working pressure of 6KPa, the condensate film demister can more effectively capture tiny droplets in the flue gas. This is because the higher working pressure helps to enhance the contact and collision between the gas and the demister surface, thereby improving the droplet capture efficiency.

[0008] Preferably, the filter assembly includes a cold water inlet, a filter box is provided inside the cold water inlet, and an installation groove is opened inside the filter box. The filter box can filter the coolant to prevent impurities in the coolant from entering the interior and reducing the efficiency of removing smoke from the flue gas.

[0009] Preferably, a filter screen is provided inside the installation groove, and magnetic blocks are connected to the outer surfaces of both sides of the filter screen, so that the filter screen can filter the coolant.

[0010] Preferably, magnets are embedded in the inner walls on both sides of the installation groove, a flow meter is connected to the top of the cold water outlet near the filter box, and a flow sensor is connected to the bottom of the flow meter. The flow meter and the flow sensor can realize real-time monitoring of the flow in the cold water outlet. When the internal flow is filtered, the filter can be removed for cleaning.

[0011] Preferably, a magnetic connection is formed between the magnetic block and the magnet, and the position and size of the magnetic block match the position and size of the magnet. The magnetic connection can fix the filter to prevent the filter from accidentally slipping out.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. The utility model is a new dust removal equipment that can be used to treat trace dust and microparticles. It is mainly used to remove dust, acid mist, water droplets, aerosols, odor, PM2.5 and other harmful substances in flue gas. It is an ideal equipment for controlling atmospheric dust pollution. It is a new type of equipment specifically used to treat some droplets existing in the current flue gas, which may break into small droplets and mist due to collision and other reasons. These droplets, mist and the dust particles they carry reduce smoke emissions and make the flue gas meet the national ultra-low emission standards.

[0014] 2. In the present invention, when the coolant enters the interior through the cold water inlet, it can be filtered through the filter screen, and the flow rate can be monitored in real time through the flow meter. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] See also Figure 1-4 The utility model provides a technical solution: a condensate liquid film demisting upgraded and improved structure, comprising a condensate liquid film demister main body 1, a first ridge-type demister 2 is arranged inside the condensate liquid film demister main body 1, a flat-plate condensation dust collector 3 is connected directly above the first ridge-type demister 2, a second ridge-type demister 7 is connected directly above the flat-plate condensation dust collector 3, a cleaning water pipe 4 is connected to the surface of the flat-plate condensation dust collector 3, a filter assembly 6 is connected to the upper end of the cleaning water pipe 4, and a hot water outlet 5 is connected to the lower end of the cleaning water pipe 4.

[0023] like Figure 1 and Figure 2-3 As shown, the first ridge-type demister 2 is of the same model as the second ridge-type demister 7. The ridge-type demister effectively captures liquid droplets carried in the flue gas through its unique multi-fold structure of corrugated plates. When mist-laden gas flows through the demister, the inertial impact of the gas causes the mist to collide with the corrugated plates. When the agglomerated droplets become large enough that their own gravity exceeds the combined force of the gas's upward force and the liquid's surface tension, the droplets are separated from the corrugated plate surface. This successfully separates and collects the majority of the droplets in the flue gas, thereby reducing the water content in the flue gas.

[0024] like Figure 3As shown, the outer dimensions of the condensate film demister body 1 are 3600 mm × 22500 mm, and the working pressure of the condensate film demister body 1 is 6.0 KPa. Under the working pressure of 6 KPa, the condensate film demister can more effectively capture tiny droplets in the flue gas. This is because the higher working pressure helps to enhance the contact and collision between the gas and the demister surface, thereby improving the droplet capture efficiency.

[0025] like Figure 4 As shown, a filter screen 604 is provided inside the installation slot 603 , and magnetic blocks 605 are connected to the outer surfaces of both sides of the filter screen 604 . The filter screen 604 can filter the coolant.

[0026] like Figure 3 and Figure 4 As shown, magnets are embedded on the inner walls on both sides of the installation groove 603, and a flow meter 606 is inserted into the top of the cold water inlet 601 near the filter box 602. The bottom of the flow meter 606 is connected to a flow sensor 607. The flow meter 606 and the flow sensor 607 can realize real-time monitoring of the flow in the cold water inlet 601. When the internal flow is filtered, the filter 604 can be disassembled for cleaning.

[0027] like Figure 3 and Figure 4 As shown, a magnetic connection is formed between the magnetic block 605 and the magnet. The position and size of the magnetic block 605 match the position and size of the magnet. The magnetic connection can fix the filter 604 to prevent the filter 604 from accidentally slipping out.

[0028] The usage and working principle of this device are as follows: the flue gas enters the condensate film demister main body 1 from the bottom, passes through the first ridge-type demister 2 for primary treatment, and continues to rise to the flat-plate condensation dust collector 3 for secondary treatment. The cleaning water pipe 1 is a pipe bend setting. The cooling water enters the circulating cold water inlet 601 of the bend, is discharged from the hot water inlet 5, and continues to rise to the second ridge-type demister 7. After being cleaned by water, it falls and mixes with the slurry at the bottom, reducing smoke and dust emissions and making the flue gas meet the national ultra-low emission standards. When the coolant enters the interior through the cold water inlet 601, it can be filtered through the filter 604, and the flow rate can be monitored in real time through the flow meter 606. When the flow rate is small, it means that there are many impurities on the surface of the filter 604 and blockage has occurred. At this time, the filter 604 can be pulled out for cleaning. The cleaned filter 604 can be inserted into the installation slot 603 for continued use. A sealing ring is provided on the surface of the filter 604 to prevent cooling water from leaking.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
