[0004] A heat exchanger device for chemical reactions in the above patent has the following deficiencies: when in use, the above device exchanges heat through the cooling water in the spiral water pipe and the gas in the heat exchange body to increase the contact area with the chemical gas and improve the heat exchange efficiency, but its contact area is still low, and the gas at the edge of some heat exchange bodies is still difficult to fully pass through the water pipe for heat exchange and is discharged to the outside, so the heat exchange effect is low, and the direct introduction of chemical gas also causes pollution and damage to the pipes and the inside of the heat exchange body, which in turn reduces the overall durability of the heat exchanger.

[0005] To this end, we propose a chemical reaction heat exchanger to solve the above problems. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0030] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0031] A chemical reaction heat exchanger provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings. Embodiment 1:

[0032] Combination Figure 1-Figure 3 As shown, the utility model provides a chemical reaction heat exchanger,

[0033] Specifically, it includes a body 1, and a gas injection connecting pipe 7 and an exhaust connecting pipe 8 are respectively installed on the upper left side and the lower right side of the body 1. The gas injection connecting pipe 7 and the exhaust connecting pipe 8 are mainly used to improve the introduction of gas and prevent leakage. At the same time, it is also convenient to fill and install the active sieving material 14. The inner sides of the gas injection connecting pipe 7 and the exhaust connecting pipe 8 are respectively penetrated and embedded with a water injection conduit 3 and a drainage conduit 4. The tops of the gas injection connecting pipe 7 and the exhaust connecting pipe 8 are respectively penetrated and connected with a gas injection pipe 5 and an exhaust pipe 6. A serpentine conduit member 9 is provided between the inside of the body 1. The serpentine conduit member 9 includes a conduit outer shell 901, a conduit inner shell 902, a ventilation cavity 903 and a water guide cavity 904. The two ends of the serpentine conduit member 9 respectively penetrate the upper left side and the lower right side of the body 1, and the end faces of the two ends of the serpentine conduit member 9 are respectively connected to the gas injection connecting pipe 7 and the exhaust Ventilation pipes 13 are installed through the mutually abutting end surfaces of the connecting pipe 8, and multiple groups of metal heat-conducting springs 11 and elastic extrusion pads 12 are respectively installed in the ventilation cavity 903. The ventilation cavity 903 is formed between the outer shell 901 of the catheter and the inner shell 902 of the catheter, and the water-conducting cavity 904 is opened on the inner side of the inner shell 902 of the catheter. The interior of the gas injection connecting pipe 7 and the ventilation cavity 903 are interconnected through the ventilation pipe 13, and the water-conducting cavity 904 is respectively connected to the water injection catheter 3 and the drainage catheter 4. One end of the metal heat-conducting spring 11 is connected to one end of the elastic extrusion pad 12, and the other end is fitted with one side of the inner shell 902 of the catheter. The operation and use of the above-mentioned components enables the heat exchange between the chemical gas and the cooling water to be simultaneously and comprehensively replaced through the metal heat-conducting spring 11, thereby improving the comprehensiveness of the heat exchange and improving the heat exchange effect. Embodiment 2:

[0034] Combination Figure 2 and Figure 3 As shown, based on the first embodiment,

[0035] Specifically, the other end of the elastic extrusion pad 12 is connected to one side of the conduit outer shell 901, and the inner sides of the gas injection connecting pipe 7 and the exhaust connecting pipe 8 are filled with active screening material 14. The active screening material 14 is mainly made of a filter screen made of activated carbon. The activated carbon has the function of absorbing and diluting some harmful substances and gases, so that the pollution damage of the introduced chemical gas to the serpentine conduit member 9 is reduced. At the same time, the metal thermal conductive spring 11 in the above-mentioned embodiment 1 mainly exchanges heat with the chemical gas, and the elastic protection of the elastic extrusion pad 12 also improves the overall durability.

[0036] Combination Figure 1 and Figure 2 As shown, in the above embodiment,

[0037] Specifically, a plurality of heat dissipation ventilation grilles 10 are symmetrically provided at the front and rear ends and the left and right sides of the device body 1. The heat dissipation ventilation grilles 10 are mainly used to improve the heat dissipation inside the device body 1 and reduce the temperature increase of the serpentine duct member 9 due to heat exchange. A mounting support base 2 is installed at the bottom of the device body 1. The mounting support base 2 is mainly used to facilitate the support of the device body 1 as a whole and to facilitate installation and fixation.

[0038] The working principle and use process of the utility model are as follows: First, when in use, the gas injection pipe 5 introduces the chemical gas into the interior of the ventilation cavity 903 formed by the serpentine conduit member 9 through the gas injection connecting pipe 7 and the ventilation pipe 13, and at the same time, the water injection pipe 3 also introduces the cooling water into the interior of the water guide cavity 904 formed by the serpentine conduit member 9, so that the metal heat-conducting spring 11 in the ventilation cavity 903 fully guides the coldness of the cooling water and the heat of the chemical gas to exchange with each other. After the heat exchange is completed, the cooling water and the gas are discharged to the designated position through the drainage pipe 4 and the exhaust pipe 6 on the exhaust connecting pipe 8 respectively. The heat exchange method not only increases the comprehensiveness of heat exchange, but also improves the heat exchange effect. Secondly, when in use, when the above-mentioned components are used, the gas introduced into the gas injection connecting pipe 7 is first filtered by the active screening material 14 filled inside and then introduced into the ventilation cavity 903. At the same time, the main heat exchange reaction is carried out through the guidance of the metal heat-conducting spring sheet 11, and the elastic protection of the elastic extrusion pad 12 also slows down the loss of the metal heat-conducting spring sheet 11. This not only slows down the damage and pollution to the conduit outer shell 901 and the conduit inner shell 902 composed of the serpentine conduit member 9, but also improves the overall durability of the heat exchanger.
