Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A condensate water recycling device of a boiling fiber alkali deweighting machine, referring to fig. 1, comprises a water bath tank 1 with a hollow structure, wherein the water bath tank 1 is made of a heat insulating material, and is correspondingly provided with a liquid inlet and a pressure release valve for supplementing a heating medium. The alkali liquor pipe of the alkali deweighting machine passes through the water bath tank 1 so that the worker can heat the alkali liquor pipe by using the water bath tank 1.

The water bath tank 1 is connected with a heat exchange tube 2, the heat exchange tube 2 penetrates through the water bath tank 1, and two ends of the heat exchange tube respectively extend out of the water bath tank 1. The heat exchange tube 2 is arranged at one section of the water bath tank 1 and spirally surrounds the alkali liquor tube of the alkali weight reducing machine.

One end of the heat exchange tube 2 is communicated with a steam source of a plant area, the other end of the heat exchange tube is an output end, and residual steam and condensate water after use are discharged from the output end. In order to ensure that the residual condensed water and steam can smoothly separate from the output end of the heat exchange tube 2, the heat exchange tube 2 is integrally arranged to extend longitudinally, i.e. the length of the spiral end extends longitudinally.

Referring to fig. 2, in order to save water and improve resource recycling rate, a mechanism for collecting condensed water and residual steam is connected to an output end of the heat exchange pipe 2, which mainly includes an intermediate tank 3, a steam recycling mechanism 4, and a storage tank 5.

Referring to fig. 3, the middle box 3 is a hollow structure, and a gas-liquid inlet 31 and an exhaust port 32 for communicating the inner cavity with the outside are formed at the upper part of the middle box. The output end of the heat exchange tube 2 extends downwards and is communicated with a gas-liquid inlet 31; the exhaust port 32 communicates with the steam reuse mechanism 4.

A liquid outlet 33 communicating the inner cavity and the outside is formed in the bottom surface of the intermediate case 3, and the liquid outlet 33 is communicated with the storage case 5 (shown in fig. 2). The storage box 5 is hollow and has an upper opening structure.

When the heat exchange pipe is used, residual steam and condensed water in the heat exchange pipe 2 enter the middle box body 3 through the gas-liquid inlet 31, wherein the condensed water is separated from the middle box body 3 through the liquid outlet 33 and enters the storage box body 5 to be stored and recycled; and the remaining steam is delivered to the steam reusing mechanism 4 through the exhaust port 32.

Referring to fig. 3, in order to prevent steam from escaping from the drain port 33 and interfering with the use effect, an automatic opening/closing mechanism is attached to the drain port 33.

The automatic opening and closing mechanism has two types:

Referring to fig. 3, the self-opening and closing mechanism includes a floating ball floor drain 61. The float floor drain 61 is fixed in the liquid outlet 33. When the condensed water in the middle box body 3 reaches a quantity enough to enable the floating ball to float upwards, the floating ball floor drain 61 is opened for the condensed water to pass through; when the water quantity in the middle box body 3 is insufficient, the floating ball floor drain 61 is closed to prevent the steam from being separated from the liquid outlet 33. At this time, the storage case 5 (shown in fig. 2) is placed directly below the drain port 33.

Referring to fig. 4 and 5, the automatic opening and closing mechanism includes a liquid level sensor 62, a controller 63, a liquid pipe 64, and an electric control valve 65. The liquid level sensor 62 is fixedly arranged in the middle box body 3 and used for sensing the liquid level in the inner cavity of the middle box body, and the electric signal is connected to the controller 63; the controller 63 is electrically connected with an electric control valve 65, the electric control valve 65 is arranged on a liquid conveying pipe 64, one end of the liquid conveying pipe 64 is communicated with the liquid outlet 33, and the other end of the liquid conveying pipe is communicated with the storage box body 5.

The controller 63 includes an MCU, in which a liquid discharge threshold is preset; when the liquid level detection value fed back to the controller 63 by the liquid level sensor 62 meets the liquid drainage threshold value, the controller 63 controls the electronic control valve 65 to open so that the condensed water enters the storage tank 5 from the intermediate tank 3.

Referring to fig. 3, the condensed water enters the storage tank 5 to be reused, and the remaining steam enters the steam reuse mechanism 4. The steam recycling mechanism 4 comprises a preheating sleeve 41, wherein the preheating sleeve 41 is in a hollow column shape, is sleeved on an alkali liquor pipe of the alkali deweighting machine, and is positioned at one end of the alkali liquor pipe which does not enter the water bath box. The inner wall surface of the preheating sleeve 41 is made of heat conducting materials so as to enhance the using effect.

A preheating groove 42 is formed in the preheating sleeve 41 along the length direction, and the preheating groove 42 is formed around the alkaline liquor pipe. A secondary air intake duct 43 and a liquid discharge duct 44 communicate with the preheating jacket 41. One end of the secondary intake duct 43 communicates with the exhaust port 32 of the intermediate box 3, and the other end communicates with the preheating tank 42. The drain 44 is connected at one end to the side of the preheating tank 42 facing downward and at the other end to the storage tank 5 (shown in fig. 2).

The rest steam leaves the middle box body 3 from the exhaust port 32 and enters the preheating groove 42 through the secondary air inlet pipeline 43, after the alkali liquor pipe is preheated, the steam is condensed into condensed water which falls on the bottom surface of the preheating groove 42 and is conveyed to the storage box body 5 through the liquid discharge pipeline 44 to be reused.

The steam utilization rate can be improved by the steam reuse mechanism 4, and the total energy consumption is relatively small.

The drainage pipe 44 is connected to the downward end of the guiding groove 421.

Since the steam used in the plant is often provided by the thermal power plant, which is always inevitably acidic, the condensed water is biased towards acidity. In order to avoid the interference of the pH value of the condensed water on the alkali reduction treatment, acid-base equilibrium is needed before the condensed water is used.

For this reason, referring to fig. 2 and 5, a digital PH detector 7 is disposed in the storage tank 5, and a detection end of the digital PH detector 7 is inserted below the liquid level in the storage tank 5 to detect the PH value thereof for the staff to use.

Further, the digital display type PH detector 7 is electrically connected to the controller 63 (if the floating ball floor drain is selected from the opening and closing mechanism, a controller is additionally provided). An alarm 8 is arranged on the outer wall of the storage box body 5, the alarm 8 can be a buzzer, and the electric signal of the alarm is connected to the controller 63.

A PH alarm threshold value is preset in the controller 63, and when the PH detection value fed back to the controller 63 by the digital display type PH detector 7 accords with the PH alarm threshold value, the controller 63 correspondingly controls the alarm 8 to start alarm so as to warn a worker.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
