Embodiment Construction

[0013] Such as figure 1 with figure 2 Shown: a pretreatment device for waste incineration flue gas, which includes a gravity settling chamber 15 and a cyclone dust collector 20. The gravity settling chamber 15 and the cyclone dust collector 20 are respectively installed on the fixed wall 7 through the integral frame 10 made of metal material and the bracket 25 made of metal material.

[0014] The upper part of the gravity settling chamber 15 is the gravity settling chamber furnace chamber 11, and the middle damping partition wall 13 divides the gravity settling chamber furnace chamber 11 into the smoke furnace chamber 5 and the smoke discharge furnace chamber 1 in the middle of the gravity sedimentation chamber furnace chamber 11. The middle of the middle damping partition wall 13 is the middle damping partition wall frame 16 made of metal material. Both sides of the inner wall of the gravity settling chamber furnace chamber 11 and the middle damping partition wall 13 are p...

Abstract

The invention discloses a device for pretreating waste incineration smoke. A gravity settling chamber and a cyclone dust remover are respectively arranged on a fixed wall body through an integral frame and a bracket. A furnace chamber of the gravity settling chamber is divided into a smoke inlet furnace chamber and a smoke outlet furnace chamber by using an intermediate damping partition wall. The upside and the downside of the intermediate damping partition wall are respectively provided with an upper smoke flow through hole and a lower smoke flow through hole. The smoke inlet furnace chamber is provided with a smoke inlet I. The smoke outlet furnace chamber is provided with a smoke outlet I. The smoke outlet I is connected with the cyclone dust remover through a smoke channel pup joint.An ash collector hopper I and a helical conveyor are sequentially arranged under the furnace chamber of the gravity settling chamber. A smoke separating chamber of the cyclone dust remover is provided with a smoke outlet II connected with the smoke channel pup joint. A smoke outlet chamber is arranged at the upper part of the smoke separating chamber. A smoke outlet II is arranged on the smoke outlet chamber. An ash collector hopper II is arranged under the smoke separating chamber. Due to the adoption of the invention, rough particle dust and fine particle dust in high-temperature smoke are effectively settled and separated, and residual volatile matters and powdered carbon in the high-temperature smoke are combusted, so that the smoke is better purified.

Description

technical field [0001] The invention relates to a flue gas treatment device, in particular to a pretreatment device for waste incineration flue gas. Background technique [0002] At present, there are many domestic and foreign domestic waste disposal methods, and incineration treatment is a relatively common method. The sources of garbage in domestic waste incineration plants are mainly waste generated by urban residents in their daily lives, garbage collected by urban sanitation and cleaning departments, and rural garbage. The soil content in domestic garbage is relatively high, and some cities even reach 40%. According to my country's domestic waste incineration pollution control standards, dry treatment devices (such as bag dust removal, etc.) must be used for flue gas treatment. Due to the high soil content in domestic waste, a large amount of granular dust is entrained in the flue gas. Making baghouses etc. is stressful and expensive to run. Contents of the invention...
