Description

Technical Field

[0001] The utility model relates to the technical field of steam recovery, in particular to a boiler steam recovery system. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler. In order to avoid steam waste, the boiler steam needs to be recovered. The publication number is:

[0003] The "boiler steam recovery device" disclosed in "CN217686687U" has solved the technical drawback that the waste heat of steam cannot be effectively utilized, resulting in the inability to efficiently heat the water liquid, thus affecting the utilization effect. However, in actual use, boiler steam recovery systems with similar structures still have many defects. For example, it does not have the function of automatic descaling, which causes the steam recovery system to easily produce scale during long-term use. Scale will reduce the effect of gas-liquid separation. The existing steam recovery system cannot fully separate the steam and water, resulting in moisture deposition in the pipeline, which easily causes the internal pressure of the pipeline to increase, thereby causing the pipeline to burst. Therefore, it is necessary to design a boiler steam recovery system. Utility Model Content

[0004] The purpose of the utility model is to provide a boiler steam recovery system to solve the problems raised in the above background technology.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The radio frequency electronic water treatment device is powered on to generate a high-frequency electromagnetic field to magnetize the liquefied water source. After the water body absorbs the high-frequency electromagnetic energy, the calcium and magnesium ions in the water cannot combine with the carbonate ions to form calcium carbonate and magnesium carbonate, thereby achieving the effect of scale prevention. At the same time, because the water body absorbs a large number of excited electrons, the original scale on the pipe wall gradually softens and even falls off, achieving an effective descaling effect. The absorption of a large number of excited electrons in the water body can effectively remove oxygen from the water, thereby achieving the function of deoxygenation, avoiding the oxygen in the water from increasing the pipeline pressure during pipeline transmission, and ensuring the safety of liquefied water source transportation.

[0013] 2. The steam is spirally transported through the spiral disk to increase the contact area with the steam and fully separate the water content in the steam. The separated water is deposited at the bottom of the inner tank, and the separated steam is further separated into gas and liquid through the dehydration disk and then rises to the inside of the steam pipe. The water vapor is then separated in multiple stages through the dehydration disk inside the steam pipe, thereby achieving the function of drying the steam. This effectively solves the problem that the water content in the steam is deposited in the pipeline, which easily causes the internal pressure of the pipeline to increase, thus causing the pipeline to burst, and ensures the safety of the steam during transmission.

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a boiler steam recovery system proposed by the utility model comprises an outer tank body 1, a steam pipe 5, and a stirring mechanism 6. An inner tank body 101 is fixedly installed inside the outer tank body 1, a sealed tank cover 103 is threadedly installed on the top of the outer tank body 1, a gas distributor 2 is fixedly installed on the top of the sealed tank cover 103, a radio frequency electronic water treatment instrument 202 is fixedly installed on the top of the gas distributor 2, a steam pipe 5 extending to the inside of the inner tank body 101 is fixedly installed inside the gas distributor 2, and a steam pipe 5 is fixedly installed on the outside of the steam pipe 5. A spiral disk 501 is installed, and the spiral disk 501 is in contact with the inner wall of the inner tank body 101. A dewatering disk 502 is equidistantly installed inside the steam pipe 5.

[0022] It should be noted that: the radio frequency electronic water treatment device 202 is powered on to generate a high-frequency electromagnetic field, which is transmitted to the water body condensed inside the inner tank 101, so that the water body absorbs the high-frequency electromagnetic energy, and its physical structure changes. The original associated chain macromolecules are broken into single water molecules, and the positive and negative ions of the dissolved salt in the water are surrounded by single water molecules, the movement speed is reduced, the number of effective collisions is reduced, and the electrostatic attraction is reduced, so that the calcium and magnesium ions in the water cannot be combined with the carbonate ions to form calcium carbonate and magnesium carbonate, thereby achieving the effect of anti-scaling. At the same time, because the water body absorbs a large amount of excited The excited electrons increase the dipole moment of the water body and the affinity with the positive and negative ions of the salt, so that the original scale on the pipe wall gradually softens and even falls off, achieving an effective descaling effect. The water body absorbs a large number of excited electrons, which can effectively remove oxygen in the water, thereby achieving the function of deoxygenation, avoiding the oxygen in the water from increasing the pipeline pressure during pipeline transmission, ensuring the safety of water source transportation, and then filtering through the water source filter to the boiler feed water tank for water replenishment, realizing the function of water source recycling and reuse, reducing water consumption, and increasing the energy saving and environmental protection of the device;

[0023] The outer tank body 1 and the inner tank body 101 cooperate to form a double-layer tank body, and a vacuum chamber 102 is provided between the outer tank body 1 and the inner tank body 101. The vacuum chamber 102 can effectively isolate the transfer of heat, thereby solving the problem of temperature reduction caused by steam recovery and avoiding heat loss.

[0024] At the same time, the spiral disk 501 is used to spirally transport the steam to increase the contact area with the steam and fully separate the water content of the steam. The separated water content is deposited at the bottom of the inner tank body 101, and the separated steam is further separated into gas and liquid by the dewatering disk 502 and rises to the inside of the steam pipe 5. The dewatering disk 502 inside the steam pipe 5 is then used to separate the water vapor in multiple stages, thereby achieving the function of drying the steam. This effectively solves the problem that the water content in the steam is deposited in the pipeline, which easily causes the internal pressure of the pipeline to increase, thereby causing the pipeline to burst, thereby ensuring the safety of the steam during transmission.

[0027] Furthermore, a steam inlet 203 is fixedly installed on one side of the gas distribution seat 2 , and a controller 201 is fixedly installed on the front side of the gas distribution seat 2 .

[0030] It should be noted that the exhaust pipe 302 transports the steam after gas-liquid separation to the steam filter 3, and after the dry steam is filtered by the filter element 301 inside the steam filter 3, it is supplied to the steam equipment through the pipeline. At the same time, the flow rate of the exhaust steam is monitored in real time through the air flow detector 303, which is convenient for the staff to control the steam supply amount.

[0031] Furthermore, a metering pump 402 is fixedly installed on the top of the water quality detector 403 , and a medicine tank 401 is fixedly installed on the top of the metering pump 402 .

[0032] It should be noted that: the pH value of the water source inside the inner tank body 101 is tested by the water quality detector 403, and the test result is transmitted to the controller 201 through a wire for calculation. The metering pump 402 is powered on and operated according to the calculation result of the controller 201. By powering on the metering pump 402, the liquid medicine in the medicine tank 401 is sucked and transported to the inner tank body 101, thereby realizing the function of quantitative dosing.

The liquefied water source flows into the bottom of the inner tank body 101 through the liquid hole 602 for collection, and a vacuum chamber 102 is provided between the outer tank body 1 and the inner tank body 101 to form a vacuum tube, which can reduce the heat loss of the water source.

[0035] The working principle is: the boiler is connected to the steam inlet 203 through a pipeline, the steam discharged from the boiler enters the gas distributor 2 through the steam inlet 203, and the steam is spirally transported along the spiral disk 501 to the inner tank body 101;

[0036] The spiral disc 501 is used to spirally transport the steam, increasing the contact surface with the steam, and fully separating the steam water. The separated water is deposited at the bottom of the inner tank 101, and the separated steam is further separated into gas and liquid by the dewatering disc 502 and then rises to the inside of the steam pipe 5.

At the same time, the flow rate of the discharged steam is monitored in real time by the air flow detector 303, so that the staff can control the steam supply amount.

[0038] The liquefied water source is powered on by the radio frequency electronic water treatment device 202 to generate a high-frequency electromagnetic field for magnetization treatment, so that the water body absorbs the high-frequency electromagnetic energy, so that the calcium and magnesium ions in the water cannot combine with the carbonate ions to form calcium carbonate and magnesium carbonate, thereby achieving the effect of scale prevention. At the same time, because the water body absorbs a large number of excited electrons, the original scale on the pipe wall gradually softens and even falls off, achieving an effective descaling effect. The water body absorbs a large number of excited electrons, which can effectively remove oxygen from the water, thereby achieving the function of deoxygenation. After being filtered through the water source filter, it is transported to the boiler feed water tank for water replenishment, realizing the function of water source recycling and reuse, and reducing water source consumption.

[0039] The water source inside the inner tank body 101 is tested for pH by the water quality detector 403, and the test result is transmitted to the controller 201 through the wire for calculation. The quantitative pump 402 is powered on and operated according to the calculation result of the controller 201. The quantitative pump 402 is powered on and operated to suck the liquid in the medicine tank 401 and transport it to the inner tank body 101, thereby realizing the function of quantitative dosing.
