[0002] Industrial flue gas is the gaseous product of fuel combustion in industrial production of enterprises. It contains a large amount of toxic gases and other harmful substances. The existing flue gas purification equipment generally adopts the structure of a fixed filler bed, which lays the purification filler on the air-permeable hole plate arranged horizontally. The flue gas treatment device using the carbon monoxide heat value in sintering flue gas of CN202311805432.5 patent and the sintering flue gas carbon monoxide and nitrogen oxide combined removal device of CN202021463211.6 patent are similar in structure. This structure has limited contact area between flue gas and purification filler, low treatment efficiency, and inconvenient replacement of filler.

[0003] The applicant has applied for a patent with application number 2024213766018, a mobile bed type sintering flue gas treatment equipment, which uses a mobile bed to improve the purification and treatment efficiency of carbon monoxide and facilitates the replacement of carbon monoxide catalyst filler. However, the treatment efficiency is still limited.

[0004] As a further improvement, the applicant has previously applied and later disclosed a patent with application number 2024228725059, a continuous gas purification equipment. The equipment sets up vertical and horizontally separated purification areas inside the shell, then uses a continuous feeding device and a scraping mechanism to feed the material into the purification area, and discharges the material from the discharge device after purification, which can realize online replacement of filler and better improve the purification efficiency and effect of filler. However, the equipment uses a continuous feeding structure, which has the defects of complex structure, high cost, and high operation control requirements. The equipment is more suitable for the needs of enterprises with large flue gas treatment capacity, and is not suitable for small enterprises with small treatment capacity.

[0005] Therefore, it is necessary to develop a flue gas purification equipment with high purification efficiency, simple structure, and low control requirements, which is suitable for the production needs of small enterprises with low treatment capacity requirements. UTILITY MODEL CONTENT

[0006] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is: how to provide a flue gas purification equipment with high purification and treatment efficiency, simple structure, low control requirements, and more flexible use, which is suitable for the production needs of small enterprises with low treatment capacity requirements.

[0007] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0008] The utility model provides a fixed baffle type flue gas purification tower, including the vertically arranged shell, the upper and lower ends of shell are provided with air inlet and air outlet (usually air inlet is on, air outlet is below) respectively, the inner chamber of shell has the baffle of horizontal partition type installation, a plurality of purification modules are installed on the baffle with interval, its characterized in that, the purification module is whole and presents vertical long strip shape box body shape, and the air hole with the diameter less than the purification filler particle is evenly arranged on the box body, and the upper recessed space is formed to the middle position of the lower end bottom plate of purification module upwards, and the upper recessed space is connected to form the purification area of vertical section and presents inverted U shape to the opposite two sides (including left and right two sides and / or front and back two sides) and the upper side of upper recessed space, and the purification filler is filled in the purification area, and the opening is arranged on the baffle and is communicated with the lower side of baffle in the upper recessed space of each purification module.

[0009] In this way, the flue gas enters the shell through the air inlet, and then is shunted through the upper end of the purification module to reduce the flow resistance, and then flows through the purification module from all directions to the upper recessed space, and then flows downward after converging and flows downward through the lower side of the baffle, and then is discharged through the air outlet. In this way, the purification module has an upper convex three-dimensional structure, which greatly expands the area through which the flue gas can pass, improves the flue gas purification treatment efficiency, and has the characteristics of simple structure, low control requirement, and flexible use.

[0010] The fixed baffle is vertically arranged at the middle position in the upper recessed space.

[0011] In this way, the gas flowing out of the purification module can be better guided to flow downward after impacting on the fixed baffle.

[0012] A manhole and a corresponding manhole cover are arranged on the shell.

[0013] In this way, it is convenient for workers to enter the tower to replace the filler and to maintain and repair.

[0014] The air outlet is further provided with an air outlet flue gas concentration detector, and the air outlet flue gas concentration detector is connected with the alarm device.

[0015] In this way, when the concentration of the flue gas after treatment exceeds the preset value, it can be determined that the filler particles need to be replaced, the machine can be stopped, and the workers can enter the tower to replace the filler after the flue gas in the inner chamber of the shell is emptied.

[0016] The air inlet and the air outlet are further provided with on-off valves.

[0017] In this way, it is convenient to close the air inlet and the air outlet when the filler needs to be replaced.

[0018] An exhaust pipeline is further arranged on the shell, an exhaust pump is arranged on the exhaust pipeline, and the exhaust pipeline is connected with the front pipeline system connected with the air inlet.

[0019] In this way, when the packing needs to be replaced, the gas inlet and the gas outlet are closed, and then the exhaust pump is opened to exhaust the gas in the tower to the pipeline system before the gas inlet, so that the packing replacement is facilitated.

[0020] The gas inlet position is internally provided with a gas inlet flue gas detector for detecting the flow or interference components of the gas inlet.

[0021] In this way, when the gas inlet flue gas detector detects that the flow of the incoming flue gas is too large or that the flue gas contains high-activity interference components that are not targeted, the butterfly valve mechanism can be started to open the communication port to allow the flue gas to bypass, so that as much flue gas as possible does not flow through the packing and directly bypasses to the flue gas outlet, thereby protecting the purification packing from rapid deactivation.

[0022] The butterfly valve mechanism includes a butterfly valve plate corresponding to the communication port, and a butterfly valve shaft is arranged in the middle of the butterfly valve plate.

[0023] In this way, the butterfly valve motor is installed outside the shell, which is more convenient for maintenance.

[0024] The purification module has a rectangular body structure, and the shell has a rectangular structure in the horizontal section.

[0025] Alternatively, the lower end of the purification module is fixed to the partition plate, and the upper end is open upward.

[0026] In this way, the purification module with a fixed structure is simpler in structure, and when the packing needs to be replaced, workers can enter the tower to replace the packing by using the pipeline suction method.

[0027] Alternatively, the purification module has an overall structure with a sealed upper end, and the lower end is installed on the opening position of the partition plate, and the width of the purification module is smaller than the diameter of the manhole.

[0028] In this way, the purification module with an overall structure is convenient for overall disassembly and replacement.

[0029] The lower end of the shell is provided with a support around the upper end.

[0030] Therefore, the present application realizes efficient flue gas purification under normal conditions, reduces the cost of flue gas purification by nearly 25%, and realizes automatic processing of abnormal flue gas, thereby ensuring that the flue gas pollutant purification is in a high-efficiency and stable operation state for a long time.

[0031] In summary, the utility model has the advantages of high flue gas purification treatment efficiency, simple structure, low control requirement and flexible use, and is particularly suitable for small enterprises with low treatment capacity requirement. BRIEF DESCRIPTION OF DRAWINGS
