Self-cleaning type laboratory exhaust device

Abstract

The invention provides a self-cleaning type laboratory exhaust device, which comprises a device main body, a device main body air inlet, a suction fan and a device main body air outlet; the device main body is internally positioned below the suction fan and successively provided with a flushing device, a drying device, a filter screen component, a second cleaning device and an initial effect filter screen from top to bottom; the filter screen component is horizontally arranged on the device main body and successively comprises an HEPA (high efficiency particulate air) high-efficiency filter screen and an electrostatic filter screen, the HEPA high-efficiency filter screen and the electrostatic filter screen are cleaned by a first cleaning device arranged in the device main body; a water storage tank is arranged at the bottom of the interior of the device main body and connected with the flushing device through a first water pipe, and the first water pipe is provided with a first water pump; the bottom of the interior of the device main body is provided with a water collecting groove device on which a water discharge pipe is arranged; and a controller is further arranged in the device main body which is connected with the suction fan, the second cleaning device, the flushing device, the first water pump, the drying device and the first cleaning device. The self-cleaning type laboratory exhaust device has the advantage of automatically cleaning the filter screen.

Description

technical field [0001] The invention relates to the technical field of exhaust devices, in particular to a self-cleaning laboratory exhaust device. Background technique [0002] In the laboratory, a large amount of exhaust gas will be generated during the chemical experiment. If the exhaust gas is not discharged in time, it will affect the experimental operation and adversely affect the health of the laboratory staff. Generally, the laboratory will be equipped with an exhaust device. Through ventilation The device and the exhaust pipe discharge the exhaust gas to the outside. During the long-term use of the exhaust device, because the exhaust gas is filtered through the filter in the exhaust device, there is a lot of dirt in the filter, which will affect the efficiency of the exhaust gas. As a result, the filter needs to be cleaned. When cleaning the filter screen of the existing laboratory exhaust device, the filter screen needs to be disassembled for cleaning, and there i...
