As shown in fig. 1, the self-excitation type water bath dust remover comprises a tower body, wherein the tower body is hollow, an air inlet 1 is formed in the tower body, a water tank 9 is arranged at the bottom of the tower body, an air outlet 4 is formed in the top of the tower body, an induced draft fan 10 is connected to the air outlet 4, the air inlet 1 is communicated with the upper part of the water tank 9, a guide plate 2 is arranged above the water tank 9, the guide plate 2 is provided with an S-shaped guide channel, water flows from the water tank 9 to the bottom of the guide channel of the guide plate 2, the bottom of the guide channel is upwards after water enters from the side close to the air inlet 1, and finally water flows out from the side far away from the air inlet 1. The deflector 2 in fig. 1 is formed by two blades to form an S-shaped deflector channel, and the deflector 2 has two pieces and is symmetrically arranged on two sides above the water tank 9.

Two water baffles 3 are arranged above the outer part of the water tank 9 in the tower body, the water baffles 3 are positioned between the air outlet 4 and the water outlet of the guide plate 2, and the purified air is dehydrated through the water baffles 3 at the two sides. The position of the air inlet 1 is higher than the bottommost end of the guide plate 2.

A water supplementing tank 5 is arranged outside the tower body, and the water supplementing tank 5 is communicated with the water outlet of the guide plate 2. A water supplementing valve 6 is arranged in the water supplementing tank 5. The water replenishing valve 6 can be an automatic water replenishing valve, and after the water in the water tank 9 is evaporated, the water can be automatically replenished through the automatic water replenishing valve 6.

The bottom of the tower body is provided with a blow-down valve 7, and the blow-down valve 7 is communicated with a water tank 9. The bottom of the tower body is also provided with a cleaning door 8, the cleaning door 8 is communicated with a water tank 9, and the bottom of the water tank 9 is inclined from the cleaning door 8 to the blow-down valve 7 from high to low. When the apparatus is operated for a while, the water in the water tank 9 contains a large amount of sludge, and periodic sewage discharge is required for better purification.

The working principle of the utility model is as follows: the dust-containing gas from the drying equipment enters the water tank 9 from the air inlet 1 in the middle part of the self-excited water bath dust remover, and the flow speed of the dust-containing gas changes due to the negative pressure effect of the induced draft fan 10, so that the large particles settle and impact the water surface in the water tank 9, and the dust-containing gas is primarily purified. Under the action of the front-back pressure difference of the s-shaped guide plate 2, high and low water levels are formed on two sides of the guide plate 2, the water level of the water tank 9 is lowered, air flows impact the water surface, turns and flows into the bottom of the s-shaped guide plate 2, the s-shaped guide plate 2 consists of an upper blade and a lower blade, the air flows rapidly enter the bottom of the s-shaped guide plate 2 and carry a large amount of water to pass through gaps together, the water and the air flows are fully mixed at the top of the s-shaped guide plate 2, and the dust capturing opportunity is increased. The air passes through the s-shaped guide plates 2 at the two sides and drives the water in the water tank 9 to roll along the guide plates 2 in a waterfall shape, so that a large amount of water drops are excited, and the dust-containing air is fully contacted with the waterfall flow, thereby achieving the purpose of purifying the air. On the other hand, dust and dust-containing water drops are thrown to the inner surfaces of the two blades of the s-shaped guide plate 2 due to centrifugal force and flow into the water tank 9 along with water flow for secondary purification. The purified gas is dehydrated upwards through the high-efficiency water baffles 3 on the two sides, fog drops carried out in the gas are removed through the water baffles 3, the water drops are settled in water, and finally the gas is discharged along with negative pressure of the induced draft fan 10 through the air outlet 4. In fig. 1, arrows indicate the flow direction of the exhaust gas, and broken lines indicate the flow direction of the water.
