Description

Technical Field

[0001] This utility model relates to the field of gas generator set technology, and in particular to a novel gas filter for generator sets. Background Technology

[0002] With continuous technological advancements, the types of gas that can be used in gas-fired generator sets have become increasingly diverse. This has expanded from traditional natural gas, biogas, coalbed methane, and coal gas to include coking gas, ferroalloy tail gas, straw gas, oil shale gas, semi-coke gas, and other artificially produced combustible gases. Most of these gases contain impurities such as dust and solid particles. Improper handling of these impurities before supplying the gas to the generator set can not only affect the generator set's operational stability and efficiency, leading to increased equipment failure rates and higher operating costs, but also cause blockages, abnormal wear and corrosion, shorten equipment lifespan, and in severe cases, render the equipment inoperable or even scrapped.

[0003] Currently, centralized, integrated gas purification and treatment facilities are often installed in gas-fired internal combustion engine power generation projects to meet the operational requirements of all generator units for gas quality and other parameters. However, in actual cases, sometimes after project completion, due to poor management of the gas purification and treatment equipment or equipment malfunctions, the gas purification quality fails to meet standards during certain periods. Furthermore, some projects lack effective protective gas filtration equipment before the generator units, resulting in excessive levels of dust, particulate matter, and other impurities entering the gas generator units, causing serious damage to their operation. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of gas filter for generator sets, which serves as a protective filtration device after centralized purification facilities and before gas generator sets. This addresses the problem in the prior art where the content of impurities such as dust and particulate matter entering the generator set exceeds the standard, thereby causing damage to the generator set, in the event of malfunctions in the front-end purification equipment.

[0005] This utility model provides a novel gas filter for generator sets, comprising:

[0006] The top cover assembly is installed on top of the filter housing;

[0007] The filter housing has a filter element fixing slot on its bottom plate, a drain hole seat at the bottom of the bottom plate, and is connected to the top cover plate assembly at the top.

[0008] A combined drainage assembly is installed at the bottom of the filter housing;

[0009] The inlet-side pressure measurement assembly and the outlet-side pressure measurement assembly are respectively installed in the inlet and outlet pipes of the filter housing;

[0010] The C-type combined filter element is made of a porous plate as the core material and skeleton, and is entirely covered with water-resistant filter material. It is pre-bent in a C-shape and installed inside the filter housing.

[0011] In a further improvement, the upper cover plate assembly is welded together from a machined circular steel plate and two handles, and a filter element fixing groove is provided under the circular steel plate.

[0012] In a further improvement, the filter housing is welded from steel pipe, flange, and steel plate, and has an air inlet pipe and an air outlet pipe, with pressure detection holes pre-installed on the air inlet pipe and the air outlet pipe respectively.

[0013] A further improvement is the combined drainage assembly, which is installed on a pre-drainage hole seat at the bottom of the filter housing.

[0014] In a further improvement, the inlet-side pressure measurement component and the outlet-side pressure measurement component are used to obtain the pressure difference between the front and rear of the C-type combined filter element.

[0015] A further improvement is that the perforated plate is a steel perforated plate.

[0016] As a further improvement, the filter housing is an overall cylindrical structure with an air inlet pipe and an air outlet pipe.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The gas filter configured in the generator set can prevent the content of dust, particulate matter and other impurities entering the gas generator set from exceeding the standard, thereby reducing serious damage caused by the operation of the generator set.

[0019] (2) The gas filter is installed as a separate device on the intake branch pipe in front of the gas generator set in a straight-through structure, which is extremely convenient to install and does not require a base or other supporting structure. Through the overall structural design, the flow area of ​​the filter element is fully enlarged, and the pressure of the intake airflow on the filter element ensures a tight fit between the filter element and the shell. Thus, the structure is simplified while ensuring the filtration effect.

[0020] (3) The gas filter can conveniently determine the replacement time of the filter element and the overall working status of the purification system by detecting the pressure difference before and after the filter element. When the gas is dirty due to abnormal operation of the front-end centralized purification equipment, it can be used as a protective filter device. It can give an abnormal operation prompt by rapidly increasing the pressure difference of the filter element, and then protect the generator set at the back end. This makes it easier to judge the working condition and facilitates the maintenance of the equipment. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0028] like Figure 1-4 As shown, a novel gas filter for generator sets according to a specific embodiment of the present utility model includes: an upper cover plate assembly 1, a sealing gasket 2, a filter housing 3, a combined drainage assembly 4, an inlet-side pressure measuring assembly 5, a C-type combined filter element 6, and an outlet-side pressure measuring assembly 7.

[0029] The top cover assembly 1 is welded from a precision-machined circular steel plate and two handles. A filter element fixing slot is provided under the steel plate. The sealing gasket 2 is made of rubber or similar material. The filter housing 3 is welded from steel pipe, flange, and steel plate. It is a cylindrical structure with inlet and outlet pipes. Pressure detection holes are reserved on the inlet and outlet pipes respectively. A filter element fixing slot is provided on the bottom plate. There is a drain hole seat at the bottom of the bottom plate and a flange at the top for connecting with the top cover assembly 1. The combined drainage component 4 is a general standard part and is installed on the drain hole seat reserved at the bottom of the filter housing 3. The inlet-side pressure measuring component 5 and the outlet-side pressure measuring component 7 are also general standard parts and are installed on the inlet and outlet pipes of the filter housing 3 respectively, which have reserved pressure detection holes. The C-type combined filter element 6 is made of steel porous plate as core material and skeleton and is covered with water-resistant filter material. The whole part is in a C-shaped pre-bent shape.

[0030] Work process:

[0031] After placing the C-type combined filter element 6 in the pre-drilled filter element fixing slot on the bottom plate of the filter housing 3, ensuring a good fit between its bottom and sides and the filter housing 3, and correctly placing the sealing gasket 2, place the upper cover plate assembly 1 on the filter housing 3. Ensure that the upper side of the C-type combined filter element 6 is embedded in the pre-drilled filter element slot at the bottom of the upper cover plate assembly 1 and fits well. Then, use bolts to fasten the upper cover plate assembly 1 and the filter housing 3 into a single unit. Next, install the new type of gas filter on the intake branch pipe in front of the gas generator set via a flange connection. During installation, follow the airflow direction indicated on the housing and do not install it backwards. Also, ensure that the upper cover plate assembly 1 is vertically upward during installation. After installation, with normal gas supply and unit operation, the gas enters from the filter inlet side (outer side of the arc apex of the C-type combined filter element 6), is filtered and purified by the C-type combined filter element 6, and flows out from the filter outlet side (inner side of the arc apex of the C-type combined filter element 6). During operation: The pressure difference between the front and rear sides of the C-type combination filter element 6 is detected by the inlet side pressure measuring component 5 and the outlet side pressure measuring component 7. The working status of the C-type combination filter element 6 is judged based on the pressure difference. When the pressure difference exceeds the specified value, the upper cover plate assembly 1 is opened and the C-type combination filter element 6 is replaced. At the same time, the water, oil and other liquid impurities accumulated at the bottom of the filter housing 3 are discharged periodically through the combined drainage component 4.

[0032] The novel gas filter for generator sets provided in this embodiment can achieve the following functions: It can be installed as a standalone device on the intake branch pipe before the gas generator set in a straight-through structure, making installation extremely convenient and eliminating the need for a base or other supporting structure; through the overall structural design, the flow area of ​​the filter element is fully enlarged, and the pressure of the intake airflow ensures a tight fit between the filter element and the housing; by detecting the pressure difference across the filter element, the replacement time of the filter element and the overall working status of the purification system can be easily determined; when the gas is heavily contaminated due to malfunctions in the front-end centralized purification equipment, it can act as a protective filtration device, providing an abnormal operation warning through rapid increases in the filter element pressure difference, thereby protecting the downstream generator set. This utility model can effectively solve the problem in the prior art where the content of impurities such as dust and particulate matter entering the generator set exceeds the standard when the front-end purification equipment malfunctions, thus causing damage to the generator set.

[0033] To cope with corrosive gas, this type of filter can be made entirely of corrosion-resistant materials such as stainless steel.
