Microsoft Yahei, structure
Microsoft Yahei
Microsoft Yahei Black water film dust collector The water film dust collector is mainly composed of the air inlet part, the middle section of the cylinder, and the introduction part.
Microsoft Yahei
Microsoft Yahei granite desulfurization purifier is composed of desulfurization chamber, aerosol mixer, atomization system, swirl plate, water pump and liquid supply line, and external dehydrator.
Microsoft Yahei
Microsoft Yahei According to the initial smoke and dust emission characteristics of the coal-fired chain-fired boiler, the original wet method dust collector is used in the first stage of this plan.
Microsoft Yahei
Microsoft Yahei (Based on the initial smoke and dust emission characteristics of coal-fired chain-fired boilers, the first stage of this plan uses the original water film dust collector, dust removal efficiency, dust collector resistance mm water column, In the ash discharge method, the ash particles are thrown onto the water film on the wall of the cylinder, and are sent to the bottom ash hopper by the water film. They are discharged from the ash discharge port and enter the sedimentation tank. Due to the hard texture of granite, it is corrosion-resistant, wear-resistant, acid-resistant, and alkali-resistant. It is durable and can be used for more than a hundred years. The longest one has been used for more than 100 years and is still the same.)
Microsoft Yahei
The second stage of Microsoft Yahei adopts / type desulfurization purifier with high desulfurization efficiency. , the main body is made of granite structure, the inner wall is made of epoxy resin cement grooves, the built-in mass transfer structure is made of acid-resistant stainless steel, the main body is made of granite masonry, and the cylinder is made of corrosion-resistant, wear-resistant, erosion-resistant, high-temperature-resistant epoxy resin cement, and built-in stainless steel The combination of material components ensures long service life.

Microsoft Yahei, dust removal and desulfurization principle
Microsoft Yahei
Microsoft Yahei type granite desulfurization and purification equipment, its principle is to use alkali The alkaline liquid and the sulfur dioxide and fine dust in the flue gas are strongly mixed in the three phases of gas, liquid and solid. During the mass transfer process, the alkaline absorption liquid forms mist droplets, liquid nets and liquid films, which pass through a series of processes in the desulfurization device. Chemical reactions are completed in physical processes such as collision, impact, remixing, condensation and efficient separation, and sulfur dioxide and fine dust in the flue gas are removed to achieve efficient purification.
Microsoft Yahei
Microsoft Yahei's first-stage high-efficiency water film dust collector is a mechanical centrifugal dust removal equipment. It is a circular cylinder. The flue gas is introduced tangentially along the lower part of the cylinder due to the attraction of the induced draft fan. , spiraling up in the cylinder, the gray water and ash particles are separated with the flue gas under the action of centrifugal force. The flue gas is led out from the top of the cylinder in a tangential axial direction or a volute, and the gray water droplets and ash particles are thrown onto the water film on the cylinder wall. , is sent to the bottom ash hopper by the water film, and is discharged from the cylinder through the ash discharge port, thereby achieving the purpose of dust removal.
Microsoft Yahei
The main body of Microsoft Yahei's second-stage/type high-efficiency combined granite desulfurization and dust removal device is a cylindrical structure. The flue gas after dust removal enters the desulfurization chamber. At this time, the moisture content of the flue gas has Reaching the saturated state, the flue gas passes through the swirl plate, transforms from turbulent flow to swirling flow, and then mixes with the aerosol mixture in the upper part of the cylinder body, and then impacts and mixes with the absorption liquid sprayed from the atomization system set in the middle of the cylinder body. Finally, after mass transfer, the flue gas passes through the upper swirl plate, and the collected flue dust and desulfurization products form a liquid film and drain along the cylinder. This is a strongly mixed mass transfer and separation process of gas, liquid, and solid phases. Due to The action of flue gas passing through the swirl plate. The flue gas completes the transition from turbulent flow to swirling flow, and rotates downward on the inner wall of the cylinder. The liquid mist condenses to form a water film, which flows down the wall and enters the bottom. The dust and desulfurization products are discharged into the circulating pool for precipitation. Desulfurization is completed.
Microsoft Yahei
The flue gas purified by Microsoft Yahei enters the external dehydrator. The external dehydrator has a stronger defogging, dehydration and diverting structure, which effectively reduces the moisture content of the flue gas. discharge. Effective technical measures improve operational reliability.
