Filtering and ventilating device in chimney

Abstract

The invention discloses a filtering and ventilating device in a chimney. The filtering and ventilating device comprises a chimney, a ventilation cavity is formed in the chimney, the lower end of the ventilation cavity is in communication with a household cooking bench, a speed measuring device is arranged in the ventilation cavity, the speed measuring device comprises a rotatable mounting block, three fan blades are uniformly and fixedly arranged on the mounting block, the flue gas or hot gas in the ventilation cavity is discharged from bottom to top, and the circulation of the gas can push the fan blades to rotate. According to the filtering and ventilating device, the gas circulation speed in the ventilation cavity is detected through the speed measurement device, so that the swing of asealing plate is controlled through the circulation speed, the swing angle of the sealing plate can control the gas circulation volume of the ventilation cavity, so that the gas is stably circulated,secondly, the swinging of the sealing plate is linked with the rotation of a filter ring, adsorption blocks with different tightness are arranged in the filter ring, harmful substances or large-particle substances in the gas are subjected to adsorption treatment when gas circulation is guaranteed, and pollution of the exhaust gas to air is reduced.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a filtering ventilation device in a chimney. Background technique [0002] A chimney is a structure that provides ventilation for the hot flue gas or smoke of a boiler, furnace or fireplace. When the flue gas in the chimney is directly discharged to the outside, the harmful substances or large particles inside will pollute the space and increase the environmental burden. Therefore, The gas in the chimney needs to be treated and discharged. The existing gas treatment device in the chimney is fixedly installed in the chimney. The processing device does not set the emission and processing capacity of the flue gas. Adjustment, the problem of reduced use value, and when the discharge volume is large, the load of the processing device is low, and the processing efficiency of the gas is reduced. The present invention illustrates a device capable of solving the above-mentioned probl...
