Diaphragm air pressure tank is an energy storage device composed of a steel shell and a rubber diaphragm liner. The rubber diaphragm completely separates the water chamber from the air chamber. When water with external pressure is filled into the liner of the diaphragm air pressure tank, the air sealed in the diaphragm air pressure tank will be compressed. Shaanxi Gas fired hot blast stove According to Boyle's gas law, the volume of gas becomes smaller after being compressed, and the pressure increases to store energy. The expansion of compressed gas can press the water in the rubber diaphragm out of the tank. Diaphragm pressure tank is widely used in central air conditioning, boiler, water heater, frequency conversion and constant pressure water supply equipment. It can buffer the pressure fluctuation of the system and eliminate water hammer to stabilize the pressure and unload the load. small-scale Gas fired hot blast stove factory When the water pressure in the system changes slightly, the automatic expansion and contraction of the diaphragm air pressure capsule will have a buffer effect on the change of water pressure, which can ensure the stability of the water pressure in the system, and the water pump will not be opened frequently due to the change of pressure.

It can only be prevented by adding medicine to the pot. Shaanxi Gas fired hot blast stove Adding drugs to the boiler can further soften the water quality, making up that the softening water equipment cannot replace silicon, sulfur and heavy metal ions and anions, so that impurities such as suspended solids, water slag and scale in dissolved water have good looseness and fluidity, and then the impurities are discharged by sewage, thus preventing scale. The water treatment method is carried out in the pot, so it is called water treatment method in the pot. small-scale Gas fired hot blast stove factory Therefore, boiler water treatment actually includes water treatment of feed water and quantitative feeding treatment in the boiler. Water treatment should only be carried out without adding drugs. The boiler water index basically does not meet the specified requirements, and the boiler cannot operate under good water quality. This is also the main reason for the softened water device. The softened water is also qualified, and the boiler will also be polluted.

When the boiler is shut down, the temperature of the heat transfer oil can be reduced to below 70 ℃ before the shutdown of the hot oil pump. In case of sudden power failure, extinguish the fire immediately, and then implement the operating procedures. Otherwise, the furnace tube will be burned out and the loss will be large. According to the type of heat transfer oil boiler, heat transfer oil shall be reasonably selected to prevent overheating. Shaanxi Gas fired hot blast stove When purchasing unqualified heat transfer oil, do not save money or mix heat transfer oil indiscriminately. Otherwise, the consequences will be very serious. Prevent the oxidation of heat transfer oil. The strict heat transfer oil is more than 50 degrees in contact with the air, which will make the heat transfer oil crack. Its speed is amazing, and the consequences are relatively serious. After normal operation, the test crew needs to close the exhaust valve on the auxiliary exhaust pipe. After 6 months of use, the heat transfer oil must be sampled and tested according to the instructions. If problems are found, the heat transfer oil must be replaced immediately. small-scale Gas fired hot blast stove factory However, it should be noted that different types of heat transfer oil should not be mixed. The circulation speed of the heat transfer oil should not be less than 1.5m/s. Due to the excessive temperature difference between some entrances and exits, the original design requirements were destroyed, the heat transfer oil could not maintain the original circulation state, the boundary layer became thicker, and the thermal resistance became larger, making the furnace wall exceed the oil film temperature, leading to carbon deposition, cracking, polymerization, coking, and even burning through the furnace tube.

The waste heat boiler is composed of drum, movable smoke hood, feeding pipe groove, oxygen lance mouth, furnace mouth section flue, inclined section 1 flue, inclined section 2 flue, last section 1 flue, last section 2 flue, nitrogen sealing device and nitrogen sealing plug, manhole, micro differential pressure tapping device, flue support and hanger. Shaanxi Gas fired hot blast stove Unlike conventional boilers, waste heat boilers do not produce combustion process and do not have combustion related equipment. Essentially, they are just gas water/steam heat exchangers. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of flue is introduced from the drum through downcomer to the lower header of each flue, and then enters into each heating surface. The water passes through the heating surface and generates steam into the header, and then is introduced into the drum through the riser. small-scale Gas fired hot blast stove factory The needle tube waste heat recovery device is a special high-efficient energy-saving product specially designed for waste heat recovery of flue gas. The heat recovery boiler uses needle shaped tubes to strengthen the heat elements to expand the heating surface. The heating surface on the water pipe smoke side can be greatly increased. At the same time, the smoke will form strong turbulence when passing through the needle shaped tube surface, which will improve the heat transfer efficiency and reduce the soot accumulation.

The manufacturer of the pneumatic water tank shall hold the pressure vessel manufacturing license or registration, and have a sound quality management system and system. Shaanxi Gas fired hot blast stove The purchased parts of the equipment must have the product certificate and pass the entrance inspection before use. The pneumatic water tank, water pump unit, electrical components and other components of the three-dimensional elastic filler manufacturer's equipment shall be assembled and used after passing the inspection. The equipment assembled on site can be used to inspect the performance of the whole machine on site. The production license issued by the relevant department shall be held. small-scale Gas fired hot blast stove factory When selecting this product, requirements shall be put forward for the following items: equipment composition, equipment classification, equipment working pressure, equipment design flow, specification and quantity of air pressure tank, equipment data, and sanitary requirements. The overall structure of equipment, water pipe, gas pipe and electrical circuit shall be arranged reasonably, and the manufacturer of single hole mold aerator shall reserve space for device maintenance to facilitate operation. The pipeline of the equipment shall be equipped with a safety valve, and the opening pressure of the combined packing manufacturer shall not be greater than 1.1 times of the working pressure. The equipment shared by fire fighting and living (production) shall have a separate fire water outlet.

The hardness of water is mainly formed and expressed by calcium and magnesium, so cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component forming scale) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of the resin to remove Ca2+and Mg2+gradually decreases. Shaanxi Gas fired hot blast stove When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank to replace the hardness ions on the resin. With the regeneration waste liquid discharged out of the tank, the resin will resume its softening and exchange function. small-scale Gas fired hot blast stove factory Since the hardness of water is mainly formed by calcium and magnesium and represents that the hardness of water is mainly formed by calcium and magnesium and represents the principle of sodium ion exchange and softening treatment, the principle is to pass raw water through sodium type cation exchange resin, so that the hardness components Ca2+and Mg2+in the water can exchange with the Na+in the resin, thereby adsorbing Ca2+ Mg2+， Soften the water.
