Description

Technical Field

[0001] This utility model relates to the field of flue gas analysis technology, and in particular to a cooling and filtering device for flue gas analysis. Background Technology

[0002] When large-scale combustion operations are carried out in enterprises and factories, a large amount of harmful flue gas is generated and released into the air, causing significant pollution to the environment. Enterprises need to use flue gas analyzers to test the emissions before they are released, and emissions can only be carried out after they meet the standards. When the flue gas is first generated, the temperature is high, and the flue gas contains a large amount of soot, which can affect the detection of the flue gas analyzer. Therefore, the flue gas needs to be filtered and cooled before testing.

[0003] A search of Chinese Patent Publication No. CN218331339U reveals a high-precision flue gas analyzer, comprising an analyzer casing, a cooling box fixedly installed on one side of the bottom of the analyzer casing, several mounting components fixedly installed on the inner wall of the cooling box, cooling pipes fixedly installed on the mounting components, a semiconductor cooler fixedly installed on the outer wall of the cooling box, an analyzer body fixedly installed at the center of the bottom of the analyzer casing, a purification box fixedly installed on the bottom of the analyzer casing away from the cooling box, cooling pipes penetrating the side wall of the cooling box and communicating with the analyzer body, the analyzer body and the purification box being connected by a connecting pipe, an exhaust pipe penetrating the outer wall of the analyzer casing being connected to the purification box, and an exhaust filtration mechanism provided at the top of the analyzer casing, including an exhaust fan fixedly installed at the top of the analyzer casing, a filter box fixedly installed on the outer wall of the analyzer casing near the cooling box, several filter screens fixedly and slidably installed inside the filter box, the exhaust fan being connected to the filter box through an exhaust pipe, and a folded corrugated pipe being connected to the other end of the exhaust fan.

[0004] As the usage time increases, the amount of dust filtered on the filter screen gradually increases, which may affect the efficiency of flue gas passage and thus affect the accuracy of analysis. Utility Model Content

[0005] The purpose of this invention is to provide a cooling and filtering device for flue gas analysis in order to solve the above-mentioned problems.

An air outlet pipe 102 is fixedly connected to the top of the filter box 1. A cooling box 301 is fixedly connected to the outlet of the air outlet pipe 102. The cooling box 301 is fixed to the top of the filter box 1. Water is supplied to the cooling box 301 through a water supply assembly. A refrigeration assembly is installed inside a water tank 401. The refrigeration assembly adopts a semiconductor refrigerator or other existing equipment capable of refrigeration. The water supply assembly includes a water tank 401 bolted to the rear side of the filter box 1. A water pump 402 is fixedly connected to the top of the water tank 401. An inlet pipe 403 is fixedly connected to the outlet of the water pump 402. The other end of the inlet pipe 403 extends into the cooling box 301. An outlet pipe 404 is also fixedly connected between the cooling box 301 and the water tank 401.

[0020] An exhaust pipe 303 is fixedly connected to the side of the cooling box 301 away from the exhaust pipe 102. A serpentine pipe 302 is fixedly connected between the inner walls of the cooling box 301 and the exhaust pipe 303. The other end of the exhaust pipe 303 is fixedly connected to the flue gas analyzer body 304.

[0021] The filter box 1 is equipped with a filter mechanism, which includes a loop frame 201 that is movably installed between the inner walls of the filter box 1 via an elastic component. The elastic component includes two sets of springs 203 arranged in front and behind. The front and rear inner walls of the filter box 1 are provided with sliding grooves. The loop frame 201 slides up and down along the sliding grooves, and the springs 203 are fixedly connected between the loop frame 201 and the sliding grooves.

[0022] A filter screen 202 is fixedly connected between the inner walls of the U-shaped frame 201. The filter screen 202 is elastic. A mounting bracket 206 is fixedly connected to the top of the U-shaped frame 201. An electric push rod 207 is fixedly connected to the mounting bracket 206. A fixing block 208 is fixedly connected to the bottom end of the electric push rod 207. The fixing block 208 is fixedly connected to the center of the filter screen 202. A collection box 209 is slidably connected to the bottom of the filter box 1. The front end of the collection box 209 extends out of the filter box 1 and is fixedly connected to a handle.

[0023] An extension plate 204 is fixedly connected to the inner wall of one side of the filter box 1. A trigger switch 205 is fixedly connected to the bottom of the extension plate 204. The mounting bracket 206 is located below the trigger switch 205. The trigger switch 205 is used to control the opening and closing of the electric push rod 207.

[0024] Working Principle: During operation, gas enters the filter box 1 through the inlet pipe 101, where it is filtered by the filter screen 202 to remove dust. The filtered gas then enters the serpentine tube 302 through the outlet pipe 102, and is cooled by water in the cooling box 301. The cooled gas then enters the flue gas analyzer body 304 through the exhaust pipe 303 for analysis. Simultaneously, the water pump 402 is activated, drawing cold water from the water tank 401 into the cooling box 301 through the inlet pipe 403. Water in the cooling box 301 is then returned to the water tank 401 through the outlet pipe 404, improving the cooling effect. As usage time increases, more and more dust accumulates on the filter screen 202, gradually clogging it. When the filter screen 202 becomes clogged to a certain extent, the air pressure below it increases, driving the serpentine tube... 201 moves upward, and the U-shaped frame 201 drives the mounting bracket 206 to rise. When the mounting bracket 206 abuts against the trigger switch 205, the control valve in the air intake pipe 101 closes. At the same time, the electric push rod 207 is triggered, which drives the fixed block 208 to move the center position of the filter screen 202 up and down continuously, causing the filter screen 202 to shake and shake off the dust clogging the filter screen 202 into the collection box 209 for collection. As the dust on the filter screen 202 decreases, the flue gas below the filter screen 202 gradually passes through the filter screen 202, causing the air pressure below the filter screen 202 to decrease. Under the action of the spring 203, the filter screen 202 gradually moves downward and resets. The mounting bracket 206 separates from the trigger switch 205, and then the electric push rod 207 is de-energized. The filter screen 202 stops shaking. At the same time, the air intake pipe 101 is ventilated to continue cooling and filtration.
