Description

TECHNICAL FIELD

[0001] The utility model relates to a high pressure gas filter with water circulation heating function. BACKGROUND

[0002] The gas filter is widely used in the gas engine system and is mainly used for filtering the impurities and particles in the gas to ensure the cleanliness of the gas and thus guarantee the normal operation of the engine. In the fields of vehicles, power generation equipment and the like, the gas filter is an important component in the gas supply system, and its working state directly affects the flow efficiency of the gas and the performance of the engine.

[0003] However, in a low-temperature environment, the gas filter is prone to icing due to excessively low temperature, thereby blocking the filter element and affecting the normal flow of the gas, causing insufficient gas supply of the engine and leading to a decrease in the power of the whole vehicle. In addition, after the gas passes through the filter, the internal water vapor is prone to condensing into liquid water due to the decrease in temperature, causing the related components to be stuck, further affecting the flow efficiency of the gas and even affecting the normal operation of the engine.

[0004] In the prior art, some solutions use an electric heating device to heat the gas filter, and a kind of electric heating type CNG high pressure filter (publication number: CN204851476U) is disclosed, which uses an electric heating method to increase the temperature of the filter to prevent icing. However, such an electric heating device has certain safety hazards in a gas environment, and once gas leakage occurs, the electric heating element may cause short circuit or even explosion, which has high safety risks. In addition, the electric heating method has high energy consumption, which increases the energy consumption of the vehicle or equipment during long-term use, and the heating is uneven, which may cause local overheating or insufficient heating of the filter, affecting the use effect.

[0005] Therefore, the existing heating scheme of the gas filter in a low-temperature environment still has certain defects, mainly manifested in that the safety hazards are large, the energy consumption is high, and the heating effect is uneven. Therefore, it is urgent to provide a safe and reliable, energy-efficient and compact gas filter heating scheme to solve the icing and water vapor condensation problems of the gas filter in a low-temperature environment, ensure the stable supply of the gas, and improve the operating efficiency of the engine.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] like Figs. 1-3 As shown in the figure, this utility model provides a high-pressure gas filter with water circulation heating function, including a filter canister 1, and a filter seat 2 is provided on the surface of the filter canister 1. An air outlet connector 5 and an air inlet connector 3 are respectively provided on both sides of the surface of the filter seat 2. A water drain valve 7 is provided on the lower surface of the filter canister 1. The above technical features are all mature existing technologies, and are technical solutions that are not difficult for those skilled in the art to obtain or conceive of. Those skilled in the art can make corresponding adjustments and selections based on the above technical solutions.

[0023] A filter element 10 is installed inside the filter tank 1. An inlet connector 4 and an outlet connector 6 are connected to the surface of the filter base 2. A first water passage chamber 8 is provided between the inlet connector 4 and the filter base 2, and a second water passage chamber 9 is provided between the outlet connector 6 and the filter base 2. A spiral water passage pipe 11 is installed on the lower surface of the filter base 2, and the spiral water passage pipe 11 is sleeved on the outside of the filter element 10. One end of the spiral water passage pipe 11 is connected to the interior of the first water passage chamber 8, and the other end of the spiral water passage pipe 11 is connected to the interior of the second water passage chamber 9.

[0024] In one embodiment of this utility model, the working process of the gas entering the device is as follows:

[0025] Gas enters the interior of filter canister 1 through intake connector 3. Filter element 10 filters the gas, removing impurities and particles to ensure clean gas enters the engine. After passing through filter element 10, the gas is discharged from exhaust connector 5 and delivered to the engine's gas supply system.

[0026] To prevent the filter element 10 from freezing in low-temperature environments or from condensing water vapor due to temperature drops, this device uses engine cooling water as a heat source for heating. Cooling water enters the first water passage chamber 8 through the water inlet connector 4, and then flows into the spiral water passage pipe 11. The spiral water passage pipe 11 is tightly wound around the outside of the filter element 10, allowing the cooling water to continuously release heat as it flows through the pipe, heating the filter element 10 and its surrounding environment, thus preventing ice formation on the inner wall of the filter element 10 or condensation of water vapor from the combustion gas.

[0027] The cooling water after heat exchange flows into the second water cavity 9 from the spiral water pipeline 11 and is finally discharged through the water outlet joint 6, returns to the engine cooling system and completes the water circulation heating process.

[0028] Through the above design, the utility model can effectively prevent the icing problem of the gas filter in low temperature environment, avoids the part jam caused by water vapor condensation, ensures the normal supply of gas, improves the operation efficiency of the engine and the power performance of the whole vehicle.

[0029] In the embodiment, the spiral water pipeline 11 is made of stainless steel or other high-pressure-resistant and corrosion-resistant materials. This design enables the spiral water pipeline 11 to effectively withstand high temperature and high pressure environment, prevents corrosion and leakage caused by long-term use, ensures the stability and service life of the water circulation heating system, and improves the reliability and safety of the equipment.

[0030] In the embodiment, the inner diameter of the spiral water pipeline 11 is 4-6mm. This design helps to maintain appropriate water flow rate, ensures efficient heat exchange, reduces flow resistance, avoids heat loss caused by slow water flow or insufficient heat dissipation caused by fast water flow, improves heating efficiency and system stability.

[0031] In the embodiment, the connection between the water inlet joint 4 and the filter seat 2 and the connection between the water outlet joint 6 and the filter seat 2 are both provided with sealing rubber rings. This design can effectively prevent cooling water leakage, enhance the sealing performance of the water system, improve the durability, ensure the long-term stable operation of the water circulation heating system, and avoid the influence of leakage on heating effect and equipment safety.

[0032] The above is only a preferred embodiment of the utility model, and does not limit the utility model. Any modification, equivalent replacement and improvement within the spirit and principles of the utility model should be included in the protection scope of the utility model.
