Description

Technical Field

[0001] The invention belongs to the technical field of heating devices and relates to a heating device. Background Art

[0002] Shell and tube heat exchanger is also called shell and tube heat exchanger. It is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This heat exchanger has a simple structure, low cost, wide flow cross section, and is easy to clean scale, but the heat transfer coefficient is low and the floor space is large.

[0003] For example, Chinese patent application [application publication number: CN117570756A] discloses a heat exchanger with adjustable thermal resistance, a thermal resistance control system and a method of using the same, including a tube side medium inlet, a tube side medium outlet, a shell side medium inlet, a shell side medium outlet, an upper head, a lower head, an upper tube plate, a lower tube plate, a shell, a heat transfer tube, a bottom inlet and outlet of a heat conducting medium, and a top inlet and outlet of a heat conducting medium. The heat transfer tube is a double-layer heat transfer tube, and the double-layer heat transfer tube is composed of an outer tube, a gap, and an inner tube from the outside to the inside, and the gap of the double-layer heat transfer tube is filled with a heat conducting medium according to the operating conditions of the heat exchanger.

[0004] The above structure heats the heat-conducting medium to be heated by allowing the medium to be heated to enter the shell from the shell side medium inlet and enter the heat transfer tube through the tube side medium inlet, thereby achieving heat exchange. Since the heated medium directly enters the shell, there is no good guidance in the shell, and it is heated in a single stroke, resulting in a poor heating effect. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to propose a heating device. The technical problem to be solved by the present invention is: how to solve the problem of poor heating effect of the prior art heating device.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A heating device comprises a tube body, wherein a plurality of water inlet pipes and a plurality of water outlet pipes are inserted into the tube body, and the character is characterized in that a plurality of heat pipes for installing a heat carrier are connected to the outer peripheral surface of the tube body, and the length direction of the heat pipe is arranged along the length direction of the tube body, and the two ends of the heat pipe are respectively connected to the inner cavity of the tube body, and one end of the tube body is connected to a connecting structure which connects the water outlet of the water inlet pipe with the water inlet of the water outlet pipe, and a plurality of steam deflectors are connected to the inner tube wall of the tube body, and the steam deflectors are all sleeved on the water inlet pipe and the water outlet pipe, and the outer edges of the steam deflectors form air vents with the inner wall of the tube body, and the air vents of two adjacent steam deflectors are staggered, and a plurality of drainage notches are provided on the steam deflectors.

[0008] The smoke generated by the existing combustion is blown onto the heat pipe, and the heat of the hot gas after the existing combustion equipment is used. The heat carrier in the heat pipe is vaporized after being heated to form a high-temperature gas, and enters the inner cavity of the pipe body from the air outlet at the upper end of the heat pipe, and heats the water inlet pipe and the water outlet pipe in the pipe body at the same time. By arranging a plurality of steam baffles in the pipe body, the steam baffles and the water inlet pipe and the water outlet pipe are in a sleeve-connected relationship, and the vents are arranged, a multi-layer air passage is formed between the plurality of steam baffles and the inner wall of the pipe body, thereby extending the flow path of the high-temperature gas, and by arranging the water inlet pipe and the water outlet pipe in the pipe body, The water in the water pipe is repeatedly heated by the high-temperature gas in the gas passage, thereby improving the heating efficiency of the water in the water pipe. The high-temperature gas will liquefy when it encounters the low-temperature water inlet and outlet pipes in the pipe body, and the liquefied liquid will flow to the corresponding steam baffle. In order to make the liquefied liquid quickly fall to the bottom of the pipe body, a drainage gap is opened on the steam baffle so that the liquefied liquid can be quickly discharged downward, and the liquid under the pipe body can be stably accumulated, so that the lower part of the heat pipe outside the pipe body always maintains a large amount of heat carrier, thereby improving the rapid heating of the water and increasing the heating effect of the heating device.

[0009] The present application adopts a double-stroke heating method, that is, the water needs to enter the water inlet pipe for heating and then pass through the connecting structure to enter the water outlet pipe for heating again. The double-stroke heating method improves the heating efficiency.

[0010] The heat carrier can be lithium bromide and water. When heated, the water will vaporize into high-temperature water vapor, and the concentration of lithium bromide will increase. When the high-temperature water vapor condenses through the water inlet and outlet pipes and drips to the bottom of the pipe body, the water returns to the lithium bromide solution, and the liquid concentration of the lithium bromide solution decreases.

[0011] The drainage notch may be opened on the outer edge of the steam baffle or inside the steam baffle, preferably opened on the outer edge of the steam baffle so that the condensed water can flow downward along the tube wall of the tube body.

[0012] The diameter of the drainage notch is smaller than the diameter of the vent.

[0013] In the above-mentioned heating device, a plurality of steam baffles are arranged in parallel, the air outlet of the heat pipe is located above the uppermost steam baffle, and the liquid inlet of the heat pipe is located below the lowermost steam baffle.

[0014] By setting the air outlet of the heat pipe at the top of the steam deflector, the high-temperature gas will gather at the upper part of the pipe body. In order to make the high-temperature gas flow slower, the air outlet of the heat pipe is directly set above the uppermost steam deflector, so that the high-temperature gas can remain in the upper part of the pipe body more stably, and the liquid after the high-temperature gas condenses can quickly flow into the lower part of the heat pipe, thereby ensuring the heating effect of the heating device and quickly allowing the condensed liquid to enter the heat pipe for easy heating and vaporization next time.

[0015] In the above-mentioned heating device, the tube body is in the shape of a hollow cylinder, and two adjacent vents are respectively located on the left and right sides of the tube body.

[0016] The vents are symmetrically distributed along the radial direction of the tube body, so that the entire gas passage is S-shaped, which maximizes the flow path of the high-temperature gas and improves the heating effect of the heating device.

[0017] In the above-mentioned heating device, a plurality of heat pipes are evenly distributed along the circumferential direction of the outer peripheral surface of the tube body, and a plurality of heat absorbing fins are fixedly connected to the outer side wall of the heat pipe.

[0018] The distribution of the heat pipes enables stable heating in all directions inside the pipe body, and the provision of heat-absorbing fins increases the heat-absorbing area and effect of the heat pipes, making the vaporization of the heat carrier faster and improving the heating efficiency.

[0019] In the above-mentioned heating device, the lower end wall of the heat pipe is located above the lower end surface of the pipe body.

[0020] The arrangement of this structure enables the liquid in the lower part of the tube body to quickly enter the heat pipe, thereby improving the reflux efficiency of the vaporized liquid.

[0021] In the above-mentioned heating device, a lower tube plate is fixed to the lower end of the tube body, and the connecting structure includes a hemispherical lower head, the upper end of the lower head is folded to form a lower flange, and the lower flange is fixedly connected to the lower tube plate, and the lower ends of the water inlet pipe and the water outlet pipe are both inserted into the lower tube plate and connected to the inner cavity of the lower head.

[0022] By setting the lower flange in the lower head, it is convenient to directly disassemble and clean the lower flange when not in use. The lower head uses its own shape to allow water falling to the lower end of the pipe body to quickly enter the water inlet pipe under the hemispherical guide, thereby improving the efficiency of water flow.

[0023] In the above-mentioned heating device, the lower ends of the water inlet pipe and the water outlet pipe are both inserted downward into the inner circle of the lower flange.

[0024] The arrangement of this structure enables the water inlet pipe and the water outlet pipe to quickly and stably guide the water into the lower head through the lower flange, which has a good guiding effect and accelerates the circulation of the water in the lower head.

[0025] In the above-mentioned heating device, all water inlet pipes are located on one side of the tube body, and all water outlet pipes are located on the other side of the tube body. An upper tube plate is fixed to the upper end of the tube body for inserting the upper ends of the water inlet pipes and the water outlet pipes. The heating device also includes a hemispherical upper head, the lower end of the upper head is folded to form an annular upper flange portion, the upper flange portion is fixedly connected to the upper tube plate, and a accommodating cavity is formed between the upper head and the upper tube plate. A partition is arranged in the upper tube plate or the upper head, and the partition divides the accommodating cavity into a water inlet cavity and a water outlet cavity. A cold water inlet is provided on the water inlet cavity, and a hot water outlet is provided on the water outlet cavity.

[0026] In order to improve the heating effect of the heating device, multiple water inlet pipes and water outlet pipes are arranged in the pipe body to increase the heated area, and a partition is arranged on the upper tube plate to separate the accommodating cavity, so that the two sides of the head portion correspond to the water inlet pipe and the water outlet pipe respectively. Through the position setting of the water inlet pipe and the water outlet pipe, the water inlet and outlet of all the water inlet pipes and the water outlet pipes can be realized only through the coordinated cold water inlet and hot water outlet of the two chambers, which facilitates the water inlet and outlet and can also ensure the heating effect of the heating device.

[0027] On the other hand, water liquids with different heating effects in the water outlet cavity can merge with each other in the water outlet cavity and then flow out through the hot water outlet.

[0028] In the above-mentioned heating device, the upper end of the water inlet pipe is inserted into the water inlet cavity, and the upper end of the water outlet pipe is inserted into the water outlet cavity.

[0029] The arrangement of this structure enables cold water to quickly flow into the water inlet pipe, and hot water to quickly flow from the water outlet pipe into the water outlet cavity, thereby ensuring the stability of the use of the heating device.

[0030] In the above-mentioned heating device, the plurality of heat absorbing fins are evenly distributed along the length direction of the corresponding heat pipe, and the plurality of heat absorbing fins are arranged in parallel.

[0031] The arrangement of this structure enables the heat pipe to heat up quickly and stably when heated by flue gas, thereby improving the stability of the heat pipe heating.

[0032] Compared with the prior art, this heating device has the following advantages:

[0033] 1. By arranging a plurality of steam baffles in the pipe body, the steam baffles are in a socketed relationship with the water inlet pipe and the water outlet pipe, and the vents are arranged, so that a multi-layer air passage is formed between the plurality of steam baffles and the inner wall of the pipe body, thereby extending the flow path of the high-temperature gas. In addition, by arranging the water inlet pipe and the water outlet pipe in the pipe body, the water in the water pipe is repeatedly heated by the high-temperature gas in the air passage, thereby improving the heating efficiency of the water in the water pipe.

[0034] 2. By opening a drainage gap on the outer edge of the steam baffle, the liquefied liquid can be quickly discharged downward, and the liquid under the tube body can be stably accumulated, so that the lower part of the heat pipe outside the tube body always maintains a large amount of heat carrier, which improves the rapid heating of the water liquid and increases the heating effect of the heating device.
