A chemical detecting instrument with an exhaust gas absorbing and purifying function according to claim 1, wherein: arc-shaped guide plates (6) are bolted to two sides of the top of the inner cavity of the fixed box (2), and the water tank (4) is located on one side of the arc-shaped guide plates (6) in the opposite direction.
8. A chemical detecting instrument with an exhaust gas absorbing and purifying function according to claim 1, wherein: dust covers (5) are bolted to the tops of two sides of the water tank (4), and the dust covers (5) are located on the outer sides of the air holes.
9. The chemical detecting instrument with exhaust gas absorbing and purifying function according to claim 4, wherein: the right side of the top of the second supporting plate (11) and the left side of the top of the third supporting plate (12) are both bolted with flow guide blocks, and the front side of the left side of the inner cavity of the water tank (4) is bolted with a water level sensor (19).
10. A detection method of a chemical detection instrument with an exhaust gas absorption and purification function is characterized by comprising the following steps:
s1, when in use, waste gas is generated when the chemical detection instrument body (1) detects an experimental article, at the moment, a user turns on a second air pump (31) through a controller, at the moment, the second air pump (31) provides suction for a second suction head (34), at the moment, the second suction head (34) absorbs the waste gas around the chemical detection instrument body (1), then the second suction head (34) conveys the waste gas to an air suction pipe (32) through a shunt pipe (33) so as to convey the waste gas into a vent pipe (35) through the air suction pipe (32), at the last, the vent pipe (35) conveys the waste gas into a water tank (4), at the moment, clean water in the water tank (4) adsorbs and settles dust in the waste gas, so as to primarily purify the waste gas, then the gas rises and is dissipated out of the water tank (4) through air holes, at the same time, a dust cover (5) further filters the waste gas, at the moment, at the moment, the first air pump (14) pulls the waste gas at the top of the fixed box (2) through the first suction head (16);
s2, the waste gas falls to the surface of a filter plate (13) at the top of a first support plate (10) through an arc guide plate (6) under the action of traction force, at the moment, the filter plate (13) further filters and purifies the waste gas, meanwhile, the filter plates (13) on the surfaces of a second support plate (11) and a third support plate (12) filter the waste gas for multiple times, impurities and harmful substances in the waste gas are further purified by utilizing three groups of filter plates (13), meanwhile, the residence time of the waste gas is prolonged by the first support plate (10), the second support plate (11) and the third support plate (12), so that the waste gas is purified more completely, at the moment, the waste gas continues to move under the action of the traction force until the waste gas descends to the right side of a deodorization filter screen (183), at the moment, a HEPA high-efficiency filter (181), an active carbon filter screen (182) and a deodorization filter screen (183) finally filter and purify suspended particles, so that the waste gas reaches the dischargeable standard, and finally the first air pump (14) discharges the completely purified waste gas through the gas outlet pipe (17).
