Abstract
The utility model discloses a water seal for a spray drying tower. An inner cylindrical shell (1) is arranged on an outer cylindrical shell (3), the upper end of the inner cylindrical shell (1) is communicated with air and is provided with a water inlet pipe (9), the lower end is extended to the position close to the bottom of the outer cylindrical shell (3), a vent pipeline (4) is mounted on the upper portion of the outer cylindrical shell (3), one end of a circulation pipeline (2) is communicated with the outer cylindrical shell (3), the other end of the circulation pipeline (2) is connected with the inner cylindrical shell (1), an overflow port (8) is disposed on the circulation pipeline (2), and a liquid level meter and a liquid level controller (7) are mounted on the outer cylindrical shell (3). The utility model is a water seal for a spray drying tower with simple structure, high reliability and good safety performance.
Description
Technical field
The utility model relates to a kind of water seal, particularly relates to a kind of protection water seal of system pressure in spray drying device.
Technical background
At present; spray drying device is in field extensive uses such as metallurgy, food, medicine, chemical industry; but this equipment volume is big, and air quantity is big, to the balance adjustment of system's internal gas pressure; the protection of pressure is difficulty very; again because pure automaton lacks certain sensitivity and reliability, all the time; do not have a kind of safe and reliable device, cause occurring in the industry a lot of because pressure is controlled the accident of improper generation.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, reliability is high, security is good spray drying tower water seal.
In order to solve the problems of the technologies described above, the spray drying tower water seal that the utility model provides, on outer cylinder body, be provided with inner barrel, described inner barrel upper end is communicated with atmosphere and is provided with water inlet pipe, and the lower end extends near described outer cylinder body bottom, is provided with discharge duct on the top of described outer cylinder body, circulating line one end is communicated with described outer cylinder body, the other end is connected with described inner barrel, and described circulating line is provided with gap, and described outer cylinder body is provided with liquid level gauge and fluid level controller.
Described liquid level is counted the quartz tube type liquid level gauge.
Adopt the spray drying tower water seal of technique scheme, can carry out the bidirectional protective of system's malleation and negative pressure.When system overpressure, reach the pressure differential of setting, gas is from interior tube bottom pressure release in the system; When system is under-voltage, reach the pressure differential of setting, ambient atmos enters system by water seal, realizes the balance of external and internal pressure.Fluid level controller can be realized the stable of the interior liquid level of water seal, and when being lower than design water level, system's automatic water supplement is when being higher than design water level, system's automatic overflow.The positive/negative pressure difference can be set by structural design, can be because of other former thereby inefficacy such as outage, operate miss.
In sum, the utility model is a kind of simple in structure, reliability is high, security is good spray drying tower water seal.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structure vertical view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, on outer cylinder body 3, be provided with inner barrel 1, inner barrel 1 upper end is communicated with atmosphere and is provided with water inlet pipe 9, the lower end extends near outer cylinder body 3 bottoms, be provided with discharge duct 4 on the top of outer cylinder body 3, circulating line 2 one ends are communicated with outer cylinder body 3, and the other end is connected with inner barrel 1, circulating line 2 is provided with gap 8, and outer cylinder body 3 is provided with quartz tube type liquid level gauge 6 and fluid level controller 7.
Referring to Fig. 1 and Fig. 2, discharge duct 4 is communicated with spray drying tower by taking over 5, before device start, water intaking valve is opened, and water enters in the outer cylinder body 3 by water inlet pipe 9, water level arrival desired location, and water intaking valve is closed.The utility model can carry out the bidirectional protective of system's malleation and negative pressure; according to system overpressure and under-voltage limiting pressure; structural design is carried out in water seal; the height of inner barrel 1 bottom surface arrival liquid level has determined the highest malleation of the internal system that water seal can be born, and the height that liquid level arrives discharge duct 4 porch lowest parts has determined the peak suction that water seal can be born.When system overpressure, reach the pressure differential of setting, gas is from inner barrel 1 bottom pressure release in the system; When system is under-voltage, reach the pressure differential of setting, ambient atmos enters system by the inner barrel 1 of water seal, realizes the balance of external and internal pressure.
Quartz tube type liquid level gauge 6 can be indicated the liquid level of outer cylinder body 3, and fluid level controller 7 can be realized the stable of the interior liquid level of water seal, and when being lower than design water level, system's automatic water supplement is when being higher than design water level, system's automatic overflow.
Claims (2)
1, a kind of spray drying tower water seal, it is characterized in that: on outer cylinder body (3), be provided with inner barrel (1), described inner barrel (1) upper end is communicated with atmosphere and is provided with water inlet pipe (9), the lower end extends near described outer cylinder body (3) bottom, be provided with discharge duct (4) on the top of described outer cylinder body (3), circulating line (2) one ends are communicated with described outer cylinder body (3), the other end is connected with described inner barrel (1), described circulating line (2) is provided with gap (8), and described outer cylinder body (3) is provided with liquid level gauge and fluid level controller (7).
2, spray drying tower water seal according to claim 1 is characterized in that: described liquid level is counted quartz tube type liquid level gauge (6).
