Description

TECHNICAL FIELD

[0001] The utility model relates to filter equipment technical field especially a novel high pressure water vapor filter. BACKGROUND

[0002] In the field of paper production, high pressure steam is used in multiple production processes, including the following. (1) Pulping: In the chemical pulping process, high pressure steam is used to cook wood chips or other fiber raw materials to remove impurities such as lignin, separate and soften the fibers, accelerate chemical reactions, improve pulping efficiency and quality, and ensure fiber strength and flexibility. (2) Paper drying: Wet paper after pressing contains a lot of water, which needs to be removed by drying to meet the specified moisture content. High pressure steam is used to transfer heat to wet paper through steam drying cylinders or drying equipment to evaporate water. By accurately controlling the temperature and pressure of the steam, the uniformity and stability of the paper drying can be ensured, avoiding problems such as paper deformation, wrinkling or strength reduction. (3) Glue melting: In the papermaking process, glue is used to enhance the strength and toughness of the paper. High pressure steam is used as a heat source to ensure the quality and performance of the glue, thereby improving the quality of the paper. (4) Beating: After the bark and grass are cut and put into the pot to cook and form the pulp, high pressure steam provides continuous high temperature steam, replacing the traditional manual control of the heat source, saving labor costs. In actual production, too much water in the high pressure steam will reduce the heat transfer performance and increase the steam consumption. Experimental data shows that when the water content of the steam reaches 15%, the heat transfer performance of the steam decreases by 15%, resulting in an increase of 17.65% in the amount of steam required for the same heating process. In addition, water will also cause dirt to deposit on the surface of the heat exchange equipment, reducing the heat transfer coefficient and further affecting the heating efficiency of the equipment, thereby reducing the production efficiency. Too much water in the steam will also cause a series of safety problems. Specifically, water will cause erosion and corrosion of the pipeline and pneumatic valves, making them gradually soften and even leak and leak. For control valves, the valve core and valve seat will also be eroded, causing the control valve to be unable to close tightly. In addition, water will also increase the problem of scale, which increases the safety risk. Due to the above reasons, in the existing paper production and other fields, water vapor filtration equipment is used to filter the water in high pressure steam.

[0003] In the existing papermaking production field, the steam moisture filtering equipment generally includes a filter screen and a shell, the filtering equipment is installed in a filter cylinder between an output pipe of a steam generator and an air inlet pipe of a corresponding air equipment, and moisture is absorbed by the cloth filter screen, the above-mentioned method meets the production needs to a certain extent, but is limited by the structure and has some technical problems as follows: first, the filter screen has limited ability to absorb moisture, when the steam contains a large amount of moisture, the performance of the filter screen will be poor, which will cause the moisture in the steam to enter the corresponding equipment, and adversely affect the normal operation of the corresponding equipment, so it is necessary to take out the filtering equipment to dry the filter screen in a relatively short time interval, the above-mentioned operation needs to install the drying equipment to the original position after the filtering equipment is dried, which is inconvenient for the workers and is not conducive to improving the work efficiency. Second, during work, the filtered moisture cannot be collected, so the moisture enters the related equipment and adversely affects the normal operation of the equipment. In summary, it is particularly necessary to provide a filter which can effectively filter the moisture in the steam and reduce the manual operation of the workers to take out and install the filter screen.

[0016] Figure 1 、 2As shown in the figure, the second solenoid valve DC2 and the third solenoid valve DC3 are normally closed valve core solenoid valves, and the first solenoid valve DC1 and the fourth solenoid valve DC4 are normally open valve core solenoid valves. The electric heating mechanism includes a plurality of strip-shaped electric heating pipes RT and a ring-shaped hollow fixing frame 8. The outer side end of the fixing frame 8 has external threads. Five electric heating pipes RT are fixedly installed at the left end of the fixing frame 8 at an interval. The fixing frame 8 is installed at the left end of the cylinder body 2 through external threads. The wires connected to the five electric heating pipes RT are parallelly connected and then sleeved in a heat-resistant insulating pipe and led outwards through the upper left end hole of the cylinder body 2. The hole is sealed with sealing glue. The prompting circuit includes two copper rods T, a resistor R, a transistor Q1, and an alarm H connected through the circuit board wiring. The upper left side of the water collecting cylinder 3 has two holes at an interval. The upper ends of the two copper rods T are fixedly installed on the upper left side of the water collecting cylinder 3 through bolts.

[0017] Figure 1 、 2 As shown in the figure, the first power switch S has a power input end (220V power one pole), and the power input ends 1 and 2 of the power module U1 are respectively connected to the two poles of the 220V alternating current power through wires.

[0018] Figure 1 、 2As shown, the steam water filter device body 1 is installed in the filter cylinder between the output pipe of the steam generator and the air inlet pipe of the corresponding air equipment, and the moisture is absorbed by the cloth filter screen (the above is a mature technology, and the present application will not be described again). After the power supply module U1 is powered on, the 3 and 4 pins of the power supply module U1 output stable 12V DC power to the power input end of the power switch. When the new type works, the filtered water in the steam water filter device body 1 will collect in the water collecting cylinder 3 under the action of gravity; when the water in the water collecting cylinder 3 is relatively small (on the basis of opening the power switch S3), the lower ends of the two copper rods T do not contact the water in the water collecting cylinder 3, so that the resistance value between the two copper rods T is infinite, the 12V power supply will not enter the one end of the resistor R through the two copper rods T, the triode Q1 will not be turned on, and the alarm H will not be powered on and sound, which represents that the water collecting amount in the water collecting cylinder 3 is relatively small; when the water in the water collecting cylinder 3 is relatively large, the lower ends of the two copper rods T contact the water in the water collecting cylinder 3, so that the resistance value between the two copper rods T becomes small, the 12V power supply will enter the one end of the resistor R through the two copper rods T, and then enter the base of the triode Q1, the triode Q1 will be turned on to output low level to the negative power input end of the alarm H, the alarm H will be powered on and sound, which represents that the water collecting amount in the water collecting cylinder 3 is relatively large; after the staff hear the sound, they can take out the water collecting cylinder 3 in the non-working period to pour out the water in the water collecting cylinder 3. When the steam water filter device body 1 works normally (the power switch S is opened, the electric heating pipe RT is powered on and works to heat, and the water in the steam entering the related equipment is heated, which further reduces the water in the steam entering the corresponding production equipment), the steam enters the corresponding equipment from the solenoid valve DC1 with the valve core opened, the electric heating mechanism, the steam water filter device body 1 and the solenoid valve DC4. When the steam water filter device body 1 is not used, the staff opens the power switches S and S1, so that the five electric heating pipes RT are powered on and heated, the solenoid valves DC1 and DC4 are powered on and the valve cores are closed, the solenoid valves DC2 and DC3 are powered on and the valve cores are opened, and the axial flow fan M is powered on and works. The axial flow fan M is powered on to suck the external air, then enters the rear end of the cylinder body 2 through the fixed shell 5, the solenoid valve DC2 with the valve core opened and the five electric heating pipes RT (heated to hot air), then is discharged to the air through the solenoid valve DC3 with the valve core opened, and the air flows in and out. In the process of flowing in and out, the heated air in the cloth filter screen left end input and right end output will dry the cloth filter screen under the action of heat. After the cloth filter screen is dried, the staff closes the power switch S1, the solenoid valves DC2 and DC3 lose power and the valve cores are closed, the solenoid valves DC1 and DC4 are powered on and the valve cores are opened, and the steam water in the steam water filter device body 1 can be filtered normally.

[0019] Figure 1 、 2As shown, through the above, the new type effectively collects the moisture filtered by the steam moisture filtering device body, reduces the probability of moisture entering the corresponding production equipment, and the staff can automatically dry the filter screen through the electric heating mechanism and the axial flow fan through simple power switch operation; Since the new type does not need to open the filter cartridge to take out the filter device to dry the filter screen thereof, it brings convenience to the staff, correspondingly improves the work efficiency, and saves the production cost. Figure 2 Among them, the power module U1 is an AC 220V to DC 12V power module product: the electromagnetic valves DC1, DC2, DC3 and DC4 are DC electromagnetic valves with a power of 2W; the axial flow fan M is a coaxial negative pressure fan with a power of 50W (consistent with the structure of the cooling fan of the computer host); the resistance R (voltage reduction and current limiting effect) has a resistance of 20K; the triode Q1 is a type 9013 (NPN); the alarm H is an active continuous sound alarm product with a model FQ12V; the electric heating tube RT is a straight stainless steel constant temperature electric heating tube product with a power of 500W.
