Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1 to 3, the dust fall treatment pipeline for garbage incineration provided by the utility model comprises an incineration equipment main body 1 and an exhaust structure 2 arranged on the incineration equipment main body 1. The exhaust structure 2 includes a first pipe 21 fitted at the exhaust gas discharge port of the incineration apparatus main body 1, and a spray dust settling mechanism 22 for the preliminary dust settling treatment of the exhaust gas is installed at the right end of the first pipe 21. The right end of the spraying dust fall mechanism 22 is connected with a flue gas purifier 23 through a second pipeline 24.

The spraying dust settling mechanism 22 comprises a shell 221, a spraying component 222 for spraying water resources is arranged in the shell 221, and a drain pipe 223 for discharging waste water is fixedly connected to the bottom shell wall of the shell 221.

The spraying assembly 222 comprises a water inlet pipe 2221, a distributing pipe 2222 is fixedly connected to the bottom end of the water inlet pipe 2221, and spraying pieces for spraying water are arranged at two ends of the distributing pipe 2222.

In this embodiment, the flue gas cleaner 23 includes a housing, and the inside of housing has set gradually active carbon chamber, desulfurization cavity and denitration cavity from a left side to a right side, and wherein the inside of active carbon chamber is provided with the multilayer active carbon filter screen.

A dust fall treatment pipeline theory of operation for msw incineration based on embodiment one is: when the incineration apparatus main body 1 is performing the incineration operation of the waste, the exhaust gas generated by the incineration is discharged from the exhaust gas discharge port thereof through the exhaust structure 2. The waste gas entering the exhaust structure 2 enters the spraying dust-settling mechanism 22 through the pipeline I2, and after the spraying dust-settling treatment of the water resource in the spraying dust-settling mechanism 22, the treated waste gas enters the flue gas purifier 23 through the pipeline II 24 for purification treatment and then is discharged.

When the incineration apparatus main body 1 starts to operate, the water inlet switch of the spraying assembly 222 in the spraying dust settling mechanism 22 is turned on in advance when the waste gas is treated by the spraying dust settling mechanism 22, so that water resources enter the spraying assembly 222. The water resource entering the spraying assembly 222 is sprayed from the spraying members provided at both sides by the cooperation of the water inlet pipe 2221 and the distribution pipe 2222. The sprayed water resource sprays the exhaust gas entering therein, and dust entrained in the gas after the exhaust gas is sprayed falls down with the water resource, and thus the drain pipe 223 discharges. The gas after the spraying treatment enters the flue gas purifier 23 through the second pipeline 24, and is discharged after being filtered in the flue gas purifier 23.

Example two

As shown in fig. 1, based on the first embodiment, this embodiment further includes: the first pipe 21 is fixedly connected to the exhaust gas discharge port of the incineration apparatus main body 1 by bolts. The spraying dust-settling mechanism 22 is connected with the first pipeline 21 through a flange, and the spraying dust-settling mechanism 22 is also connected with the second pipeline 24 through a flange. The flue gas purifier 23 is fixedly connected to the right end of the second pipeline 24, and an exhaust gas discharge conduit is arranged at the outlet end of the flue gas purifier 23.

In this embodiment, the flange connection between the spraying dust settling mechanism 22 and the first and second pipelines 21 and 24 not only has high tightness, but also has mature technology and convenient operation.
