However, it has the following problem during use: when treating some high-temperature flue gas, the high temperature of the flue gas can damage the filter bags upon contact, affecting their use. Therefore, a dust collector with a cooling function is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a pulse dust collector that can cool down the flue gas in advance when removing dust from high-temperature flue gas, thus preventing damage to the dust removal mechanism caused by the high-temperature flue gas. It is easy to use, reliable and practical.

[0004] This utility model discloses a pulse dust collector, comprising a base plate, a support frame, a dust collection box, and an exhaust pipe. The dust collection box is fixedly mounted on the base plate via the support frame. The dust collection box contains a chamber, and an exhaust pipe communicating with the chamber is located at the top of the dust collection box. An electromagnetic valve is mounted on the exhaust pipe. The device also includes a cooling mechanism and a dust removal mechanism. The cooling mechanism is mounted on the base plate and communicates with the lower part of the dust collection box chamber. The dust removal mechanism is installed within the dust collection box chamber and performs dust removal. The exhaust pipe for high-temperature flue gas is connected to the cooling mechanism, and the exhaust pipe is connected to an external waste gas treatment system. When treating high-temperature flue gas, the flue gas enters the cooling mechanism for cooling, then enters the chamber of the dust collection box. After being dusted by the dust removal mechanism, the flue gas is discharged through the exhaust pipe into the external waste gas treatment system for further treatment. This device can pre-cool the flue gas during dust removal, preventing damage to the dust removal mechanism. It is convenient to use and has high reliability and practicality.

[0005] Preferably, the cooling mechanism includes a water tank, a conveying pipe A, an air inlet pipe, multiple heat exchange pipes, a conveying pipe B, and a gas delivery pipe. The water tank is fixedly installed on the base plate and has a water cavity inside. The conveying pipe A is fixedly installed at the left end of the water tank, and an air inlet pipe is installed at the input end of the conveying pipe A. The left ends of the multiple heat exchange pipes are all connected to the conveying pipe A, and the right ends of the multiple heat exchange pipes are all connected to the air inlet pipe. The multiple heat exchange pipes are all located inside the water cavity of the water tank. The input end of the gas delivery pipe is connected to the conveying pipe B, and the output end of the gas delivery pipe is connected to the chamber of the dust collector. A solenoid valve is installed on the gas delivery pipe. The water cavity of the water tank is filled with water. Multiple heat exchange tubes are submerged in water; a valve is installed on the inlet pipe to connect it to the external flue gas duct; during flue gas treatment, high-temperature flue gas enters multiple heat exchange tubes through the inlet pipe and delivery pipe A, and the flow rate and volume of the flue gas are controlled by the valve on the inlet pipe. Then, the flue gas exchanges heat with the water in the water tank through the tube walls of multiple heat exchange tubes, thus cooling the flue gas. Afterward, the flue gas enters the dust removal chamber through delivery pipe B and air supply pipe for dust removal. By cooling the flue gas in advance, damage to the dust removal components caused by high-temperature flue gas is avoided. It is convenient to use and highly practical.

[0006] Preferably, the dust removal mechanism includes a sealing partition, an installation pipe, and a support mesh. The sealing partition is fixedly installed in the upper part of the dust removal chamber, and the installation pipe is fixedly installed on the sealing partition.

The support mesh is fixedly installed at the lower end of the installation pipe, and the support mesh is located below the sealing partition. A filter bag is provided on the outer wall of the support mesh, and the filter bag is fixedly covered on the outer wall of the support mesh. When the flue gas enters the chamber of the dust removal chamber, the flue gas is filtered by the filter bag to remove dust, and the dust adheres to the outer wall of the filter bag. Then, the flue gas passes through the filter bag and enters the upper part of the dust removal chamber through the installation pipe. After filtration, the flue gas is discharged into the external waste gas treatment mechanism through the exhaust pipe for further treatment, which facilitates the filtration of flue gas.

[0007] Preferably, the assembly also includes a rotary joint, a soot blowing pipe, multiple air blowing pipes, an air supply pipe, and a rotating mechanism.

The rotating mechanism is installed on the soot blowing pipe and has a rotation function; air supply... The inlet of the pipe is connected to an external high-pressure gas storage tank. The gas in the high-pressure gas storage tank can be nitrogen or carbon dioxide. When it is necessary to clean the dust attached to the filter bag, first close the solenoid valves on the exhaust pipe and the gas supply pipe, and then open the pulse valve on the gas supply pipe. This allows the high-pressure gas in the gas storage tank to be blown into the filter bag through the gas supply pipe, rotary joint, soot blowing pipe and multiple blowing pipes in sequence. Then, the high-pressure gas is discharged into the dust collector box through the inside of the filter bag. When the high-pressure gas passes through the filter bag, it blows the dust attached to the outer wall of the filter bag into the chamber of the dust collector box.

The water pump is fixedly installed on the water tank, with its input end connected to the water chamber of the water tank and its output end connected to the water supply pipe and the nozzle. The nozzle is located above the water tank. The nozzle is fixedly installed on an external support frame. When the water in the water chamber of the water tank cools multiple heat exchange tubes, the water pump is turned on. The water pump causes the water in the water chamber of the water tank to enter the nozzle sequentially through the water pump and the water supply pipe. Then, the water is sprayed into the water tank through the nozzle. As the water falls up and down on the nozzle, it comes into contact with the outside air, promoting heat dissipation and cooling of the water.
