Description

Technical Field

[0001] This utility model relates to the field of gas analyzer technology, specifically a gas analyzer for flue gas pipelines. Background Technology

[0002] In industrial production processes such as chemical manufacturing, the emitted flue gas often contains pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter. Analyzing the composition of this flue gas using a gas analyzer not only allows for monitoring the operating status of combustion equipment and timely detection of problems such as incomplete combustion and equipment leaks, but also reduces the occurrence of excessive emissions. Therefore, gas analyzers are indispensable equipment. Due to the high temperature and high dust content of flue gas, existing gas analyzers used for pipeline flue gas detection integrate coolers and filters. However, cooling, filtration, and gas sampling components are usually fixedly installed, resulting in a large weight and size of the entire device. This makes it impossible to disassemble and adjust the equipment according to actual gas detection needs (such as whether the gas requires filtration and cooling), limiting the equipment's application scenarios and complicating the calibration process, lacking a convenient calibration structure. Therefore, there is an urgent need for a portable and flexible gas analyzer. Utility Model Content

[0003] The purpose of this invention is to provide a gas analyzer for flue gas ducts to solve the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas analyzer for flue gas ducts, comprising a movable frame and an analyzer body. The analyzer body has component grooves and a body mounting groove on both sides of its housing from top to bottom. Sliding blocks are fixedly connected to the inner walls of the two side plates of the movable frame. Damping shock absorbers are vertically mounted on the sliding blocks, which are slidably installed within the body mounting grooves. The top of the damping shock absorber contacts the top of the body mounting groove. Cooling and filtering sections and gas sampling sections are slidably installed in the component grooves on both sides. A slider adapted to the component groove is fixedly connected to one side of each of the cooling and filtering sections and the gas sampling section. Multiple calibration gas cylinders are placed on the movable frame, and the outlets of the multiple calibration gas cylinders are connected via multi-port pipes with valves.

[0005] Preferably, the movable frame is composed of a U-shaped plate, support columns and a base. Support columns are vertically fixedly connected to the four corners of the top surface of the base. The top of the support columns is fixedly connected to the bottom surface of the U-shaped plate base plate. Sliding blocks are fixedly installed on the inner walls of the two side plates of the U-shaped plate. Both the sliding blocks and the sliders are "T"-shaped sliders.

[0006] Preferably, a gas cylinder placement plate is fixedly connected to the top surface of the base, and a semi-circular groove for calibrating the placement of the gas cylinder is provided on the gas cylinder placement plate. Universal wheels are installed at the bottom of the base.

[0007] Preferably, the outer walls of the two side plates of the U-shaped plate are fitted with pipe boxes for placing gas pipes, and the top of the analyzer body is provided with a lifting handle.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a gas analyzer for flue gas pipelines, including a movable frame 1 and an analyzer body 2. The analyzer body 2 has a component slide groove 2a and a body mounting slide groove 2b respectively on both sides of the shell from top to bottom. Sliding blocks 8 are fixedly connected to the inner walls of the two side plates of the movable frame 1. A damping shock absorber 9 is vertically installed on the sliding block 8. The sliding block 8 is slidably installed in the body mounting slide groove 2b. The top of the damping shock absorber 9 is in contact with the top of the body mounting slide groove 2b. Cooling filter section 4 and gas sampling section 5 are slidably installed on the component slide grooves 2a on both sides. A slider adapted to the component slide groove 2a is fixedly connected to one side of both the cooling filter section 4 and the gas sampling section 5. Multiple calibration gas cylinders 6 are placed on the movable frame 1. The gas outlets of the multiple calibration gas cylinders 6 are connected through a multi-port pipe with a valve.

[0019] Furthermore, the movable frame 1 is composed of a U-shaped plate 1a, a support column 1b and a base 1c. The support column 1b is vertically fixedly connected to the four corners of the top surface of the base 1c. The top of the support column 1b is fixedly connected to the bottom surface of the base plate of the U-shaped plate 1a. Sliding blocks 8 are fixedly installed on the inner walls of the two side plates of the U-shaped plate 1a.

[0020] Furthermore, a gas cylinder placement plate 1d is fixedly connected to the top surface of the base 1c. The gas cylinder placement plate 1d has a semi-circular groove for calibrating the placement of the gas cylinder 6. A caster wheel 1e is installed at the bottom of the base 1c.

[0021] Furthermore, pipe boxes 7 for placing gas pipes are installed on the outer walls of both sides of the U-shaped plate 1a, and a lifting handle 3 is provided on the top of the analyzer body 2.

[0022] Furthermore, the outlet of the calibration gas cylinder 6 is connected via a multi-port pipe with a valve. The multi-port pipe is equipped with a pressure gauge and a flow meter for real-time monitoring of gas pressure and flow. The cooling and filtering section 4 consists of a filter and a condenser. The gas sampling section 5 is a pump. The cooling and filtering section 4, the gas sampling section 5, the outlet, and the gas nozzle of the analyzer body 2 are connected via gas pipelines in the order of gas analysis operation standards.

[0023] Furthermore, the sliding block 8 has holes for mounting the damping shock absorber 9, and the bottom plate of the U-shaped plate 1a has through holes for the bottom support feet of the analyzer body 2 to pass through, with a rubber buffer ring 1f at the top of the through hole.

[0024] The working process of this utility model is as follows:

[0025] like Figure 1 - Figure 4 As shown, when the gas analyzer needs to be moved as a whole, the casters 1e at the bottom of the moving frame 1 provide convenient movement capabilities, allowing the equipment to be pushed to the flue gas duct detection position. If the analyzer body 2 is used alone and does not require calibration, it can be separated from the moving frame 1 by the top lifting handle 3. During the separation process, the body mounting groove 2b of the analyzer body 2 slides relative to the sliding block 8 of the moving frame 1. The damping shock absorber 9 on the sliding block 8 plays a key role in separation or installation: during installation, the analyzer body 2 presses down, and the damping shock absorber 9 compresses and absorbs the vibration energy. Its top end slides relative to the body mounting groove 2b. The tops of slots 2b touch to form a buffer support; during separation, damping shock absorbers 9 assist in a smooth detachment, avoiding hard collisions and ensuring the stability of the internal components of the analyzer body 2; the cooling filter section 4 and the gas sampling section 5 are slidably connected to the component slide groove 2a of the analyzer body 2 via side sliders. When the flue gas to be detected needs to be filtered and cooled, the cooling filter section 4 and the gas sampling section 5 work together with the analyzer body 2. The two are integrated on both sides of the analyzer body 2 and move with the equipment to the detection point; if the gas to be measured does not need to be filtered and cooled, the cooling filter section 4 can be directly slid out of the component slide groove 2a and removed to reduce the load on the equipment and adapt to simplified detection scenarios;

[0026] During calibration, multiple calibration gas cylinders 6 are fixed to the gas cylinder placement plate 1d on the base 1c of the mobile frame 1. The outlets of the calibration gas cylinders 6 are connected via multi-port pipes with valves. The valves of the corresponding gas cylinders on the multi-port pipes are opened according to different calibration requirements, and the calibration gas is delivered to the analyzer body 2 through pipelines, thus calibrating the analyzer without the need for additional complex piping, simplifying the calibration process. Furthermore, the rubber buffer ring 1f on the U-shaped plate 1a of the mobile frame 1 provides support and cushioning in the event of damping shock absorber 9 failure, further enhancing the overall stability of the equipment.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
