Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purification box for a texturizing machine. Background Art

[0002] The treatment of waste gas in the heating box of the texturing machine is an important environmental protection issue. A common treatment method is to treat it through a waste gas treatment environmental protection device.

[0003] Specifically, the exhaust gas treatment process is as follows:

[0004] Exhaust gas collection: The exhaust gas in the heating box is first collected through the outlet pipe.

[0005] Filtration and preliminary treatment: After the exhaust gas enters the air outlet duct, it will be filtered through the filter in the filtration mechanism. This step is mainly to isolate the large particles of dust in the exhaust gas on the filter.

[0006] Cooling and adsorption: The preliminarily treated waste gas then enters the air pipe through the output end of the air pump and is input into the purification box. Here, the waste gas will be cooled by cooling water, and the gas dissolved in water and small dust particles will be adsorbed by the cooling water.

[0007] Further purification: Gases insoluble in water and acidic gases will continue to pass through the activated carbon layer and alkaline filter plate for reaction absorption to further purify the exhaust gas.

[0008] However, when the exhaust gas contacts the cooling water in the purification box, the contact between the cooling water and the exhaust gas is not sufficient, resulting in insufficient dissolution and adsorption of the gas dissolved in water and small particles of dust. Utility Model Content

[0009] In order to solve the above technical deficiencies, the utility model provides an exhaust gas purification box for a texturizing machine, which can make the gas dissolved in water and small dust particles in the exhaust gas fully contact with cooling water.

[0010] The utility model discloses an exhaust gas purification box for a texturizing machine, comprising a box body, an air inlet pipe is vertically arranged at the bottom of the box body, the lower end of the air inlet pipe is connected with the air outlet end of an air pump after passing through the box body, a one-way valve is arranged on the air inlet pipe outside the box body, a tube body is sleeved on the outer side of the air inlet pipe inside the box body, the bottom of the tube body is fixed to the bottom of the box body, a gap is left between the inner wall of the tube body and the outer wall of the air inlet pipe, the upper end of the tube body is higher than the upper end of the air inlet pipe, a through hole is arranged on the lower side wall of the tube body, a sponge is horizontally arranged on the upper side of the inside of the box body, the edge of the sponge is fixedly connected to the inner wall of the box body, an exhaust port is arranged on the upper end of the box body, a drain port is arranged at the bottom of the box body, and a valve is arranged on the drain port.

[0011] The principle of the above technical solution is that when in use, cooling water is injected into the box body, the water level of the cooling water is higher than the upper end of the air inlet pipe and lower than the upper end of the tube body, the exhaust gas is input into the air inlet pipe through the air pump, and is blown out from the end of the air inlet pipe at a high speed, and at the same time, the cooling water enters the gap between the tube body and the air inlet pipe through the through hole at the bottom of the tube body and contacts with the exhaust gas blown out at a high speed, forming an aerosol that is blown out from the upper end of the tube body, and the aerosol makes the exhaust gas fully contact with the cooling water, and after the aerosol rises and contacts the sponge, the cooling water is absorbed and retained by the sponge, and the exhaust gas passes through the sponge and is discharged from the exhaust port to the next process, and the exhaust gas further contacts with the cooling water in the sponge during the process of passing through the sponge, so that the gas dissolved in water and small particles of dust are fully dissolved and adsorbed in the cooling water.

[0012] In order to maintain the water level of cooling water in the box, a liquid level sensor is arranged in the box. The liquid level sensor is higher than the upper end of the air inlet pipe and lower than the upper end of the pipe body. A water inlet is arranged on the box body. An electromagnetic control valve is arranged on the water inlet. The liquid level sensor and the electromagnetic control valve are electrically connected to a controller. The controller controls the electromagnetic control valve to replenish water in time according to the electrical signal of the liquid level sensor.

[0013] The utility model provides an exhaust gas purification box for a texturizing machine, which has the beneficial effect of forming aerosol by the collision of cooling water and high-speed exhaust gas, so that the exhaust gas is fully in contact with the cooling water, the cooling water in the aerosol is intercepted by the sponge, and the exhaust gas is further in contact with the cooling water when passing through the sponge, so that the gas dissolved in water and small particles of dust are fully dissolved and adsorbed in the cooling water.
