Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas purification technology, and in particular to a spray flue gas purifier box. Background Technology
[0002] The exhaust gas emitted by diesel generator sets contains harmful substances such as sulfides, nitrogen oxides, and solid particles. At the same time, the outlet temperature reaches 480-500℃. Therefore, it is necessary to treat the exhaust gas to meet the relevant national and provincial regulations.
[0003] However, most long-term flue gas treatment equipment uses diffuser nozzles installed at the top to spray and settle the flue gas before it is discharged. The flue gas flow path is relatively short, and the contact between the spray water mist and the flue gas is relatively one-sided, which can easily lead to incomplete adsorption of micro-dust in the flue gas, affecting the purification quality. At the same time, the cooling effect on high-temperature flue gas is also inefficient due to the short flow path and the short heat exchange time. In addition, after the high-temperature flue gas exchanges heat with the spray water, some of the water will evaporate and be discharged to the outside with the flue gas, resulting in a reduction of the water volume in the equipment. Frequent observation and timely replenishment of water are required, which is quite labor-intensive. Utility Model Content
[0004] The purpose of this utility model is to provide a spray flue gas purifier box that can perform layered isolation of the flue gas inlet and outlet channels within a certain area, thereby performing multiple and comprehensive adsorption, sedimentation and cooling operations on the flue gas, ensuring complete purification of micro-dust in the flue gas, maintaining efficient cooling, and automatically replenishing the water consumed by high-temperature evaporation in the box to maintain the stability of the circulating spray operation and avoid manpower consumption.
[0005] To achieve the above objectives, a spray flue gas purifier box is provided, comprising: a box body, an inlet pipe fixedly connected to the top left side of the box body, an exhaust pipe fixedly connected to the top right side of the box body, a baffle plate mounted on the inner middle of the box body, the top and front and rear sides of the baffle plate being correspondingly fitted and fixed to the box body, several vertical spray pipes symmetrically mounted on the left and right sides of the baffle plate, several spiral nozzles equidistantly mounted on the outer side of the vertical spray pipes, a diversion pipe fixedly connected to the bottom of the opposite front and rear sides of the vertical spray pipes, a circulation pipe fixedly connected to the front left of the diversion pipe, the front side of the circulation pipe extending out of the box body and fixedly connected thereto, and the bottom end of the circulation pipe extending rearward into the inner side of the box body and fixedly connected thereto. A circulating pump is fixedly connected to the lower right section of the ring pipe. A water supply tank is fixedly connected to the lower left front side of the housing. A float valve is installed between the water supply tank and the housing. The float valve is located at the lower left of the water supply tank, and the float on it is located inside the water supply tank. By setting up vertical spray pipes and several spiral nozzles below the smoke inlet and exhaust pipes, the flue gas inlet and outlet channels are isolated in layers within a certain area. This allows for multiple and comprehensive adsorption, sedimentation, and cooling operations on the flue gas entering the housing, ensuring complete purification of micro-dust in the flue gas and maintaining efficient cooling. At the same time, the water supply tank and float valve are set up to automatically replenish the water consumed by high-temperature evaporation in the housing, maintaining the stable operation of the circulating pump's spraying and avoiding incomplete flue gas purification due to water shortage.
[0006] According to the aforementioned spray flue gas purifier box, the outer surface of the float of the float valve is coated with an anti-corrosion coating. This maintains the buoyancy of the float and prevents water from seeping into it, thus avoiding affecting the automatic water replenishment.
[0007] According to the aforementioned spray flue gas purifier box, a water inlet is provided at the center of the top of the water supply tank, and an external ring cover is threadedly connected to the inner side of the water inlet. It is connected to an external water inlet pipe for automated water supply.
[0008] According to the aforementioned spray flue gas purifier box, a drain valve is fitted and fixed at the lower right position of the front side of the box body. This facilitates the timely discharge of sludge settled at the bottom.
[0009] According to the aforementioned spray flue gas purifier box, a filter cover is fitted onto the outer side of the bottom end of the circulation pipe. This filter prevents the introduced spray water from being filtered and filtered to remove particles, thus avoiding clogging and pollution problems caused by the water entering the spiral nozzles.
[0010] According to the aforementioned spray flue gas purifier box, a sealing gasket ring is provided on the mating surface of both the inlet pipe and the outlet pipe. This improves the sealing performance of the flue gas entering and exiting the system.
[0011] According to the aforementioned spray flue gas purifier box, a rubber pad is fixedly connected to the rear side of the circulating pump, and the rear side of the rubber pad is correspondingly fixedly connected to the box body. This provides auxiliary support for the circulating pump while reducing the vibration impact during its operation.
[0012] According to the aforementioned spray flue gas purifier box, the baffle is made of galvanized perforated mesh and is vertically mounted above the diversion pipe. This improves the baffle's corrosion resistance and accelerates the flue gas flow rate.
[0013] The above-mentioned solution has the following beneficial effects:
[0014] In this invention, vertical spray pipes are installed in conjunction with several spiral nozzles located below the inlet and outlet pipes to achieve layered isolation of the flue gas inlet and outlet channels within a specific area. This allows for multiple and comprehensive adsorption, sedimentation, and cooling of the flue gas entering the chamber, ensuring complete purification of micro-dust in the flue gas and maintaining efficient cooling. Simultaneously, a water replenishment tank with a float valve is installed to automatically replenish the water consumed by high-temperature evaporation within the chamber, maintaining stable circulating spray operation of the circulating pump and avoiding incomplete flue gas purification due to water shortage.
[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
