Technical Field
[0001] The utility model relates to the field of silicon dioxide smoke treatment, in particular to a water seal device for silicon dioxide smoke treatment. Background Art
[0002] One of the important ways to deal with waste gas and waste liquid in the silicone industry in my country is incineration. After incineration, a large amount of smoke containing silicon dioxide will be generated. These smoke cannot be discharged directly, but need to be sprayed and cooled in a quench tower (hydrochloric acid absorption tower or washing tower). These spray absorption equipment will be filled with acidic gases when running, and these acidic gases will also fill the end of the water inlet pipe, which will corrode the pipe and valve. At present, the existing technology generally uses a water seal device to absorb such acidic gases, such as the small practical acid mist absorption device disclosed in Chinese patent CN201551943U. The patent is equipped with an outer barrel and an inner barrel, and an acid mist absorption inlet pipe is arranged in the inner barrel. The structure of the patent performs a single water seal on the acid mist.
[0003] In addition, the water seal device is filled with water seal liquid (absorption liquid). In areas with lower temperatures in winter, the water seal liquid in the water seal device is easily frozen, thus affecting the normal operation of the equipment. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.
[0021] A water seal device comprises a housing 10 and a controller; a water seal barrel 20 is arranged in the housing 10, and a first liquid inlet pipe 21, a curved pipe 22 and a second liquid inlet pipe 23 which are connected in sequence are arranged in the water seal barrel 20; the top end of the first liquid inlet pipe 21 extends out of the top of the housing 10, and the top end of the second liquid inlet pipe 23 is located in the middle and upper part of the water seal barrel 20; a detachable float unit 30 is also arranged at the top end of the second liquid inlet pipe 23; the detachable float unit 30 comprises a connecting pipe 31 and a float 32; a balance bar 33 is arranged at the lower part of the float 32, a limiting grid sheet 34 is arranged on the inner wall of the connecting pipe 31, a limiting hole 34.1 is arranged at the center of the limiting grid sheet 34, the lower end of the balance bar 33 passes through the limiting hole 34.1 and is connected to a balance column 35; the outer diameter of the balance column 35 is larger than the aperture of the limiting hole 34.1; a liquid outlet pipe 24 is arranged in the middle part of the side wall of the water seal barrel 20, and a liquid discharge pipe 25 and a liquid replenishing pipe 26 are arranged at the bottom.
[0022] Furthermore, the balance bar 33 and the balance column 35 can ensure the stability of the float 32 when it rises and falls.
[0023] Furthermore, the inner diameter of the first liquid inlet pipe 21 is greater than the inner diameter of the second liquid inlet pipe 23 .
[0024] Furthermore, the inner diameter of the first liquid inlet pipe 21 is larger than the diameter of the second liquid inlet pipe 23 . When water enters, the diameter of the pipe becomes smaller and the pressure becomes larger, which can better push the float 32 open.
[0025] Furthermore, a temperature sensor 11 and a heating coil 12 are also provided in the box body. The heating coil 12 is arranged on the inner wall of the box body 10, and the temperature sensor 11 is connected to the controller.
[0026] Furthermore, the controller is prior art and will not be described in detail here; the temperature sensor 11 transmits the temperature inside the box 10 to the controller. When the temperature reaches the set value, the controller controls the valve on the heating coil 12 to pass the heat source to heat and insulate the box 10, ensuring that the water seal barrel 20 can work normally.
[0027] Furthermore, the connecting pipe 31 of the detachable float unit 30 is threadedly connected to the top end of the second liquid inlet pipe 23 .
[0028] Furthermore, the balance rod 33 and the balance column 35 are threadedly connected.
[0029] Furthermore, the detachable float unit 30 itself is detachable for easy maintenance.
[0030] Furthermore, the water seal barrel 20, the first liquid inlet pipe 21, the curved pipe 22, the second liquid inlet pipe 23, the liquid outlet pipe 24, the liquid discharge pipe 25 and the liquid replenishing pipe 26 are all made of glass fiber reinforced plastics.
[0031] How this application works:
[0032] The device is arranged between the water inlet pipe and the quenching tower. The top of the first liquid inlet pipe 21 is connected to the front water inlet pipe, and the liquid outlet pipe 24 is connected to the subsequent quenching tower (acid mist absorption tower or washing tower).
[0033] When the water inlet pipe supplies water to the quench tower, etc. (refer to Figure 1 ), the tap water in the water inlet pipe passes through the first liquid inlet pipe 21, the bent pipe 22, and the second liquid inlet pipe 23, lifts the float 32 and enters the water seal barrel 20, the liquid level in the water seal barrel 20 rises, and then the water in the water seal barrel 20 is pumped into the quenching tower through the liquid outlet pipe 24 by the water inlet pump.
[0034] When the water inlet pipe stops flowing (refer to Figure 2 ), the float 32 falls back and blocks the top of the second liquid inlet pipe 23. The tap water in the water seal barrel 20, the tap water retained in the elbow 22 and the fallen float 32 achieve multiple isolation of the acid mist.
[0035] The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
