Description

Technical Field

[0001] The utility model relates to a synthesis furnace, in particular to an energy-saving graphite synthesis furnace. Background Art

[0002] The appearance of graphite synthesis furnace device can be traced back to the 1940s. This equipment is widely used in ammonia manufacturing, oil refining, synthesis gas, chemical synthesis and other fields in industrial production. With the development of science and technology, the application of graphite synthesis furnace in the industrial field is becoming more and more extensive, and it has also gradually expanded to the field of scientific research;

[0003] Graphite synthesis furnace is a high-temperature reaction equipment, made of graphite material as the base material, mainly used for synthesizing ammonia, hydrogen and some other gases. Its working principle is to make the reaction occur by heating the catalyst, and produce the required products under high temperature and high pressure. Graphite synthesis furnace has no special requirements for the water content of raw materials chlorine and hydrogen, and does not require pre-treatment equipment. Therefore, the process is simple, the heat transfer efficiency is high, the outlet temperature of hydrogen chloride gas is low, the product has no Fe pollution, strong corrosion resistance, small maintenance during normal operation and long equipment life. In the graphite synthesis furnace, the circulating water can take away the heat in the furnace, thereby reducing the temperature in the furnace, but in the preheating process of the graphite synthesis furnace, the circulation of circulating cooling water will take away part of the heat, resulting in a decrease in the heating rate of the graphite synthesis furnace and an increase in energy consumption. Utility Model Content

[0004] The main purpose of the utility model is to provide an energy-saving graphite synthesis furnace to solve the problem proposed in the related art that during the preheating process of the graphite synthesis furnace, the circulation of circulating water will take away part of the heat, resulting in a decrease in the heating rate of the graphite synthesis furnace and an increase in energy consumption.

[0005] In order to achieve the above-mentioned object, according to one aspect of the utility model, an energy-saving graphite synthesis furnace is provided, comprising a graphite cylinder and a first pipeline and a second pipeline arranged outside the graphite cylinder, one end of the first pipeline is connected to a water tank, the other end of the first pipeline is connected to a temperature control box, one end of the second pipeline is connected to the lower end of the temperature control box, the other end of the second pipeline is connected to the middle part of the temperature control box, a water outlet pipe is fixedly installed on the upper side wall of the temperature control box, and the water outlet pipe is connected to the water tank;

[0006] Among them, a lifting block is slidably installed in the temperature control box. The density of the cooling water changes by changing the temperature of the cooling water in the temperature control box, so that the lifting block moves up and down in the temperature control box to control the flow or stagnation of the first pipeline and the second pipeline.

[0007] Furthermore, one end of the first pipeline is connected to the middle part of the temperature control box, and the middle part of the first pipeline and the middle part of the second pipeline are both spirally wound around the outer side wall of the graphite cylinder.

[0008] Furthermore, a fixing cylinder is sleeved on the outer side of the graphite cylinder, brackets are fixedly installed on the lower surfaces of both ends of the fixing cylinder, and a bottom plate is fixedly installed on the lower surface of the bracket.

[0009] Furthermore, cylinder covers are threadedly mounted on the side walls of both sides of the fixed cylinder.

[0010] Furthermore, the temperature control box is fixedly installed on one side of the upper surface of the base plate, a box cover is fixedly installed on the upper end of the temperature control box, and guide strips are fixedly installed at the four corners of the inner wall of the temperature control box.

[0011] Furthermore, guide grooves are provided on the side walls at the four corners of the lifting block, and water flow grooves are provided at both ends of the lifting block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In this energy-saving graphite synthesis furnace, the temperature of cooling water in a temperature-controlled box is changed to change the density of the cooling water, so that the lifting block is lifted and lowered in the temperature-controlled box. When the temperature is low, the lifting block rises, allowing the cooling water to flow into the second pipeline and be retained, thereby reducing heat loss. When the temperature rises, the lifting block descends, thereby blocking the second pipeline, allowing the cooling water to flow through the outlet pipe into the water tank and realize water circulation, which is used to prevent heat accumulation from increasing energy consumption.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-Figure 5 As shown, the purpose of this embodiment is to provide an energy-saving graphite synthesis furnace, including a graphite cylinder 1 and a first pipeline 101 and a second pipeline 102 arranged on the outside of the graphite cylinder 1, one end of the first pipeline 101 is connected to a water tank, the other end of the first pipeline 101 is connected to a temperature control box 2, one end of the second pipeline 102 is connected to the lower end of the temperature control box 2, and the other end of the second pipeline 102 is connected to the middle of the temperature control box 2, and a water outlet pipe 201 is fixedly installed on the upper side wall of the temperature control box 2, and the water outlet pipe 201 is connected to the water tank;

[0022] Among them, a lifting block 202 is slidably installed in the temperature control box 2. The cooling water density changes by changing the cooling water temperature in the temperature control box 2, so that the lifting block 202 moves up and down in the temperature control box 2, which is used to control the circulation or stagnation of the first pipeline 101 and the second pipeline 102.

[0023] One end of the first pipeline 101 is connected to the middle of the temperature control box 2, and the middle of the first pipeline 101 and the middle of the second pipeline 102 are both spirally wound around the outer side wall of the graphite cylinder 1. By spirally winding the graphite cylinder 1 with the middle of the first pipeline 101 and the middle of the second pipeline 102, the contact area between the cooling water and the graphite cylinder 1 is increased, thereby improving the thermal insulation and heat dissipation effects of the graphite cylinder 1.

[0024] A fixed cylinder 103 is sleeved on the outside of the graphite cylinder 1, brackets 1031 are fixedly installed on the lower surfaces of both ends of the fixed cylinder 103, a bottom plate 1032 is fixedly installed on the lower surface of the bracket 1031, and cylinder covers 1033 are threadedly installed on the side walls of both sides of the fixed cylinder 103. The fixed cylinder 103 is used to protect the graphite cylinder 1 to prevent the graphite cylinder 1 from being directly exposed to the external environment, and the bracket 1031 is fixedly connected to the bottom plate 1032 to support and fix the graphite cylinder 1.

[0025] The temperature control box 2 is fixedly installed on one side of the upper surface of the base plate 1032, a box cover is fixedly installed on the upper end of the temperature control box 2, guide strips 203 are fixedly installed on the four corners of the inner wall of the temperature control box 2, guide grooves 2021 are provided on the four corner side walls of the lifting block 202, and water flow grooves 2022 are provided at both ends of the lifting block 202. The lifting block 202 divides the cavity in the temperature control box 2 into an upper cavity and a lower cavity, and the guide strip 203 in the temperature control box 2 is slidably engaged in the guide groove 2021, thereby limiting the movement of the lifting block 202, and the cooling water can flow between the upper cavity and the lower cavity through the water flow groove 2022, so that the lifting block 202 can float up and down in the temperature control box 2 under the influence of the buoyancy of the cooling water.

[0026] When the utility model is used, the power is turned on to connect the graphite cylinder 1 to the power supply. At this time, the graphite cylinder 1 will start to heat up. The cooling water in the water tank will enter the first pipeline 101 under the action of the water pump. Then, when flowing through the middle of the first pipeline 101, the cooling water will absorb part of the heat of the graphite cylinder 1. Then, the cooling water will enter the temperature control box 2 through the first pipeline 101. At this time, the temperature of the cooling water is relatively low, and the density of the cooling water is relatively large, so that the lifting block 202 rises under the buoyancy of the cooling water. At this time, the lifting block 202 will block the outlet pipe 201, forcing the cooling water to enter the second pipeline 102 at the lower end of the temperature control box 2. Then, the preheated cooling water will pass through the first pipeline 101. The cooling water will continue to flow through the graphite cylinder 1 through the second pipeline 102, preventing the cooling water with lower temperature from entering, reducing the heating efficiency of the graphite cylinder 1, and increasing energy consumption. When the temperature of the graphite cylinder 1 exceeds the threshold, the density of the cooling water decreases accordingly. At this time, the lifting block 202 is reduced by the buoyancy of the cooling water. The lifting block 202 starts to settle under the action of self-generated gravity and blocks the second pipeline 102. Then, the high-calorie cooling water will enter the water tank through the outlet pipe 201, and then the cooling water flowing through the water tank for cooling will enter the first pipeline 101 again, thereby reducing the temperature of the graphite cylinder 1 and preventing the heat from being dissipated in time, which will lead to heat accumulation and increase energy consumption.

Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
