Description

Foam removing device of rotary drum suction filtration collecting tank

Technical Field

The utility model belongs to the technical field of the liquid removes the foam, in particular to rotary drum suction filtration collection tank removes foam device.

Background

Foams are easily generated in the rotary drum suction filtration process in sugar alcohol processing, and the foams generated need to be subjected to defoaming treatment or defoaming treatment in time, otherwise, the generated foams are pumped out from a vacuum pump, so that sugar liquid is wasted, the yield of production line materials is reduced, and the benefit and development of enterprises are seriously influenced.

The existing defoaming method mainly comprises the following steps: mechanical stirring defoaming, wire mesh defoaming, cyclic spraying defoaming and the like. For example, chinese patent publication No. CN2222553Y discloses a defoaming gas distributor, which uses a guide plate and a multi-outlet annular flow channel to tangentially guide the material into the annular flow channel, and the gas enters the tower through the gap between the arc plates and the bottom of the annular flow channel to separate the gas from the liquid. The disadvantages of this method are: (1) the number of flow deflectors in the equipment is large, and the device is complex; (2) the top has no defoaming emergency measures. Also, for example, chinese patent publication No. CN200966766Y discloses a dynamic chinese medicine extraction and concentration tank for removing foam by circulating spray, which adopts a circulating spray method and utilizes discharged liquid to spray to remove foam. The disadvantages of this method are: (1) the single spray header has limited coverage for foam elimination; (2) the single liquid that sprays, when smuggleing secretly the foam in the play liquid when more, utilize the play liquid to spray and to the foam dissolution elimination dynamics limited.

The prior art is subject to further improvements and enhancements.

Further, a filler layer is arranged between the screen and the spraying distributor, and the filler layer is placed on the screen.

Furthermore, the spraying distributor is respectively connected with a water inlet valve and a feed valve through pipelines, the water inlet valve is communicated with a water inlet pipe, and the feed valve is communicated with a liquid material pipe.

Compared with the prior art, the utility model discloses a rotary drum suction filtration collection tank removes foam device, the inlet design is tangent with the collection tank wall, sets up the guiding gutter at jar internal wall, eliminates jar body feed liquor gravity drop and slow water conservancy diversion to tank bottoms portion in the twinkling of an eye, eliminates the foam production rate of liquid material. The spraying and defoaming device is arranged at the top of the tank, the spraying medium can be regulated and controlled, and water or liquid materials can be selected for spraying and defoaming. Meanwhile, when the foam is more, the feed liquid or water spray can be opened to dissolve and absorb the foam so as to eliminate the foam.

The utility model discloses still have following characteristics:

(1) the liquid inlet is tangent to the inner wall of the collecting tank and tangentially enters the liquid, and the wall of the tank is provided with the diversion trench, so that the device is simple and convenient to install;

(2) a stainless steel screen and a packing layer are arranged at the upper part in the tank, so that foam can be trapped conveniently, and emergency foam removal is realized;

(3) a spray distributor is refitted at the top in the tank, so that the effective coverage area for foam elimination is increased, and the defoaming efficiency is improved;

(4) and the spraying medium can be selected in various ways, multiple spraying is realized, and the foam dissolving and eliminating force is improved.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the preferred embodiment of the foam removing device of the drum filtration collecting tank of the present invention comprises a drum filtration collecting tank 1, wherein a liquid inlet 2 and a liquid outlet 3 for passing in and out liquid material and a gas outlet 4 for discharging gas in the tank are respectively disposed on the collecting tank 1. Liquid outlet 3 sets up in the bottom of holding vessel 1, the setting position of inlet 2 is higher than liquid outlet 3, gas outlet 4 sets up the top at holding vessel 1.

The liquid inlet 2 is tangential to the inner pipe wall of the collection tank 1. A diversion trench 5 is arranged between the liquid inlet 2 and the bottom of the collecting tank 1. The diversion trench 5 is arranged downwards along the inner wall of the collection tank 1 in a spiral mode, and liquid materials enter the collection tank 1 from the liquid inlet 2 along the tangential direction of the pipe wall and then gradually descend to the bottom of the tank along the diversion trench 5.

During the in-service use, when sugar or sugar alcohol liquid material gets into collection tank 1 from inlet 2 and jar wall tangential direction in, liquid gets into along setting up guiding gutter 5 at the jar wall, and the slow water conservancy diversion of rethread guiding gutter 5 is to the tank bottoms portion, eliminates jar body feed liquor gravity drop in the twinkling of an eye, reduces the foam production rate of liquid material.

A spraying and defoaming device 6 is also arranged in the collecting tank 1. The spraying defoaming device 6 comprises spraying distributors 7 uniformly distributed in the tank. The spraying distributor 7 is higher than the liquid inlet 2. A screen 8 is arranged between the spray distributor 7 and the liquid inlet 2. A packing layer 9 is arranged between the screen 8 and the spray distributor 7. The screen 8 is made of stainless steel and is used as a support of the packing layer 9. The packing layer 9 is placed above the screen 8. The height of the packing layer 9 is 200 mm-500 mm, and is determined by the property and the amount of foam. The mesh aperture of the screen 8 is determined according to the filler, the principle is that the aperture is smaller than the diameter of the filler, and the material of the screen can be selected according to the property of the feed liquid. The filler of the filler layer 9 is selected according to the foam-containing property of the liquid material and the temperature of the material. The foam in the sugar or sugar alcohol liquid material is soluble, the mass transfer is carried out between the foam and the spraying liquid, the soluble substance is dissolved and absorbed, so that the foam is eliminated, the spraying liquid medium can be selected, and the defoaming efficiency and the defoaming strength are improved.

The spraying distributor 7 is respectively connected with a water inlet valve 10 and a feed valve 11 through pipelines. The water inlet valve 10 is communicated with a water inlet pipe. Tap water or purified water can be connected into the water inlet pipe. The feed valve 11 is communicated with a liquid material pipe. The feed valve 11 is connected with a discharge pump of the rotary drum suction filtration collecting tank 1, and the sprayed solution returns to the bottom of the tank after passing through the packing layer 9 for discharging. Under normal conditions, the feed valve 11 is opened to defoam, when liquid foam is more and the dissolving and foam eliminating force is small, the feed valve 10 is opened to feed water for spraying, so that emergency spraying is realized, and water is dissolved with the foam, passes through the packing layer 9 and returns to a liquid storage area at the bottom of the tank to be discharged.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
