Tail gas treatment device for calcining pottery clay preparation process

Abstract

The invention discloses a tail gas treatment device for a calcining pottery clay preparation process. The structure of the tail gas treatment device comprises an air outlet pipe, a fan, an installingbase, a machine body, observing windows, an automatic liquid adding device and an air guiding pipe, the top of the machine body is connected with the fan through the air guiding pipe. Compared with the prior art, the tail gas treatment device has the beneficial effect that through the combined installation of an electromagnet transmission mechanism, a lifting mechanism, a rack gear transmission mechanism, an active force transmission mechanism, a liquid outlet triggering mechanism, and a NaOH solution spraying machine, the tail gas treatment device has the automatic liquid adding and liquid stopping functions, is capable of automatically spraying a NaOH solution while a tail gas enters the machine body, good in tail gas treatment effect, does not need to perform secondary treatment, and iscapable of stopping the spraying of the NaOH solution in time while no tail gas enters, thereby effectively avoiding the waste of the NaOH solution, and according to the solubility of the tail gas, automatically adjusting a spraying amount of the NaOH solution, and reducing the using cost.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment technology, in particular to a tail gas treatment device in the preparation process of calcined clay. Background technique [0002] Calcined clay has stable chemical properties. As a rubber filler, it has a smooth appearance of extruded or calendered products, and has the characteristics of acid and alkali resistance, heat resistance and electrical insulation. It can endow EPDM rubber with good insulation, air permeability, Therefore, calcined clay has been widely used in the manufacture of EPDM rubber. At present, calcined clay for EPDM rubber filler mainly relies on imported products from the United States and the United Kingdom. The exhaust gas in the process of manufacturing calcined clay contains acid gases such as SO2, SO3, CO2 and a large amount of dust. If it is not treated, it will be very harmful to the environment. burden. [0003] At present, the tail gas generated during ...

AI Technical Summary

Problems solved by technology

[0003] At present, the tail gas generated during the preparation of calcined clay reacts with the tail gas through the NaOH solution to remove the acid gas. However, due to the imperfect technology of the existing technology, it is not possible to automatically spray the NaOH solution when the tail gas enters the body, resulting in tail gas treatment. It is not clean and requires secondary treatment, and the spraying of NaOH solution cannot be stopped in time when there is no tail gas, resulting in a waste of NaOH solution. At the same time, the solubility of the tail gas produced during the preparation of calcined clay is different, and cannot be determined according to the solubility of the tail gas. More or less spraying of NaOH solution increases the cost of use
