Embodiment approach 1

[0043] Such as Figure 1-5 As shown, the unorganized waste gas and dust recovery treatment system of the sublimation workshop of the present invention has the following general structure:

[0044]The recycling system is composed of a collection cover 1, a bag filter 2 and an exhaust tube 3 connected in series through pipelines. Specifically, the collection cover 1 and the bag filter 2 are connected through a first pipeline 4. The bag filter 2 and the exhaust cylinder 3 are connected through the second pipeline 5, the first pipeline 4 is provided with an induced draft fan 6 near the collection cover 1, and the second pipeline 5 is provided with a Fan 7, the fan 7 is a high-pressure and high-flow fan, which forms a waste gas and dust recovery and treatment system. The specific treatment process is: turn on the induced draft fan 6 and the fan 7, and first pass through the collection cover 1 to collect the unorganized waste gas generated in the sublimation workshop. and dust are ...

Embodiment approach 2

[0053] see Figure 6 Shown is the second embodiment of the exhaust gas and dust recovery treatment system of the present invention. The difference between this embodiment and the first embodiment is that in order to realize the protection of the filter bag and to collect the dust into the ash hopper for convenience, the The surrounding edges of the first filter bag 10, the second filter bag 11 and the third filter bag 12 are respectively connected with a first filter disc 17, a second filter disc 18 and a third filter disc 19, the first filter disc 17, The second filter disc 18 and the third filter disc 19 are respectively evenly distributed with the same holes as the apertures on the first filter bag 10, the second filter bag 11 and the third filter bag 12, and the first filter disc 17 , the second filter disc 18 and the third filter disc 19 are disc-shaped structures, and the peripheries of the first filter disc 17, the second filter disc 18 and the third filter disc 19 are ...

Embodiment approach 3

[0056] see Figure 7 Shown is the third embodiment of the exhaust gas and dust recovery and treatment system of the present invention. The difference between this embodiment and the second embodiment is that the recovery and treatment system further includes a cooling device, and the cooling device includes a water tank 23, a water pump 24 and the spiral cooling groove 25, the spiral cooling groove 25 is arranged in the bag filter 2, and is located at the bottom of the bag filter 2, and the outlet of the first pipeline 4 is located below the spiral cooling groove 25, the The two ends of the spiral cooling tank 25 are connected with a water inlet pipe 26 and an outlet pipe 27. The other end of the water inlet pipe 26 passes through the bag filter 2 and extends into the water tank 23. The water tank 23 is preferably fixedly connected to the bag filter. 2, and the water pump 24 is connected to the water inlet pipe 26 for pumping the cooling water in the water tank 23 into the spi...

Abstract

The invention discloses a sublimation workshop unorganized waste gas and dust recovery system. The system comprises a collection hood for collecting volatilized waste gas and dust; a first pipeline, which is used for connecting the collection hood; a bag-type dust collector, which is communicated with the collection hood through the first pipeline; a second pipeline, which is used for connecting the bag-type dust collector; an exhaust funnel, which is communicated with the bag-type dust collector through the second pipeline; and a fan, which is arranged on the second pipeline; wherein the bag-type dust collector is composed of an ash hopper and a treatment cylinder located above the ash hopper, a dust collection device is arranged in the treatment cylinder and comprises a first filter bag,a second filter bag and a third filter bag, and the first filter bag, the second filter bag and the third filter bag are sequentially arranged at intervals from bottom to top. Non-organized waste gasand dust can be collected to realize organized treatment, and the dust and organic compounds in the waste gas are collected and recycled, so that resources are saved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of recovering fugitive waste gas and dust from a fine chemical workshop, in particular to a system for recovering and treating fugitive waste gas and dust from a sublimation workshop. Background technique [0002] When refining organic compounds, which involves the process of sublimation treatment of organic compounds, the present invention chooses 4,4'-diaminodiphenyl ether as an example. [0003] Specific sublimation treatment process: first add dry 4,4'-diaminodiphenyl ether into the chemical tank, vacuumize the chemical tank, and heat the chemical tank to 4,4'-diamino The temperature at which diphenyl ether can be vaporized. After gasification, 4,4'-diaminodiphenyl ether enters the clean crystallization chamber and is cooled and crystallized in the crystallization chamber. After the high-temperature sublimation is completed, the crystallization chamber is opened to manually take out 4,4'-diaminodiphenyl ether, an...
