Abstract
The invention provides a safe waste gas pretreatment device which comprises a ventilation pipe and a filter assembly installed on the ventilation pipe, a filtering groove is formed in the ventilation pipe, and a positioning boss corresponding to the filtering groove is installed in the ventilation pipe. The filter assembly comprises a filter screen inserted into the filter tank, a clamping boss clamped on the filter screen and a sealing strip block inserted into the filter tank, the clamping boss corresponds to the positioning boss, the clamping boss is fixedly mounted on the sealing strip block, and the filter screen enters the positioning boss under pushing of the clamping boss. The filter assembly further comprises an induction frame fixedly installed on the clamping boss and a touch sensor arranged on the induction frame, the induction frame is arranged on one side of the filter screen in the air inlet direction of the ventilation pipe, the induction end of the touch sensor faces the filter screen, the filter screen presses the touch sensor after being impacted by the VOCs gas to deform, and after the critical pressure is reached, the touch sensor sends a replacement signal to the outside to remind a worker to replace the filter screen.
Description
technical field [0001] The invention relates to the field of pneumatic technology, in particular to an exhaust gas safety pretreatment device. Background technique [0002] Before the VOCs gas is incinerated, the gas needs to be pre-treated by filtering and preheating. In the filtering step, the filter screen intercepts solid particles such as dust in the VOCs gas to avoid the impact of particles on the regenerative incinerator. (RTO) The ceramic regenerator in the RTO causes impact damage, and the filter screen is set in a closed cavity space, the filtering effect of the filter screen cannot be directly observed, and the filter screen needs to be taken out for observation, the process is too cumbersome, and the filter screen If the mesh state of the filter is not observed, it will easily cause the mesh of the filter to be clogged, which will affect the circulation of the gas and cause the gas treatment efficiency to be low.
