Q:The basic principle of heat exchanger is what?

The heat exchanger [is] will be part of the thermal fluid heat transfer to cold fluid equipment, also called heat exchanger. Is a kind of different temperature between two or more fluid heat transfer between the material energy saving equipment. Heat exchanger in chemical industry, petroleum, power, food and many other occupies an important place in the industrial production, its heat exchanger in chemical industry production can be used as a heater, cooler, condenser, evaporator and reboiler, etc., used widely.

Q:What are the factors affecting heat transfer rate of the chemical equipment

Cold and hot medium temperature, cold and hot, cold and hot medium heat transfer medium flow state if (fluid), thermal conductivity, heat transfer interface and other hot and cold medium heat capacity, etc

Q:Cement production technology

(1) rotary kiln, rotary kiln combustion equipment and pulverized coal combustion heat therein; As well as heat transfer equipment, raw materials absorb the heat of the gas for calcination. Sometimes other conveying equipment, from raw material feeding end to discharging end. And fuel combustion, heat transfer and the movement of raw materials must be reasonable and collaboration between the three, to make the heat generated by the fuel combustion can in raw material by rotary kiln, rotary kiln in a timely manner to the raw material, has reached the purpose of high-yield, high-quality, low consumption. (2) raw material movement in the particles in the rotary kiln, rotary kiln is more complicated. If the raw material particles on the kiln wall and the raw materials inside the layer without sliding phenomenon, raw material movement is often thought to be like this: raw materials under the action of friction, as a whole with the kiln wall rises slowly, when transferred to a certain height, the raw material layer surface and the horizontal plane Angle is equal to the Angle of the accumulation of raw materials, raw materials particles under the action of gravity, slipped along the bed

Q:The working principle of new special viscous material scatter equipment?

Working principle is as follows: moisture content in 25 to 40% of the wet material has reunited sex or agglomerate material is entered into the scattered conveying cavity, the high-speed rotation of the rotor was carried out on the material impact, shear, make the material crushing reduction.

Q:Heat conduction oil boiler equipment is normal, no pressure after running system

Search the third, check the oil and the oil pressure gauge with thermal equipment whether there is a pressure difference, if the differential big jams with thermal equipment. You can check the thermal oil system according to these points, if there is a problem can call my company advisory.

Q:The types of heat exchangers have?

according to heat transfer type classification 1, no phase change heat transfer Generally divided into heater and cooler. 2, with phase change heat transfer Generally divided into condenser and reboiler. Reboiler is divided into kettle reboiler, siphon reboiler, reboiler, evaporator, the steam generator and waste heat boiler.

Q:What is heat transfer, heat transfer is wha

Each point within the object or system, the temperature difference between heat conduction is the necessary condition. Caused by heat conduction heat transfer rate (hereinafter referred to as thermal conductive rate) is determined by the distribution of temperature within the object. Temperature field is as a flash object or the total temperature distribution of each point in the system.

Q:Should be prepared to what kind of equipment and materials and tools and equipment?

Tube plate heat exchanger products reached a mature stage, and to its high efficiency, energy saving and environmental protection advantages in feel frequently used in the field of various industries, is used to replace the original, tube and shell heat exchanger and achieved good results. The structure of the heat exchanger Tube and shell heat exchanger, also known as tube heat exchanger, heat exchange equipment, is a common standard, it has simple structure, strong and durable, low cost, wide range of wood easy to clean, the advantages of strong adaptability, the most widely used.

Q:What is the difference between diversion in heat exchanger heat exchanger and diversion?

In diversion tube heat exchanger is inside the shell side of heat exchanger tube set up within the guide tube make the before or after the end of the heat exchanger without diverting tube before use hard to make full use of the heat transfer of heat exchange tube, thereby increasing the effective heat transfer area of heat exchanger. The diversion tube used In the floating head or fixed tube plate heat exchanger, and less common in the u-tube heat exchanger.

Q:For the same device and circulating thermal coefficient and countercurrent heat transfer coefficient is what relation?

The same device, a heat transfer coefficient of downstream and upstream won't, but the gap is not big. The same device, so the heat exchange area of the same; Upstream downstream, logarithmic mean temperature difference is different Assumes that the heat transfer coefficient is consistent, fluid temperature of import and export have change Inlet temperature and temperature changes, fluid physical properties are changed, the physical properties changed little Fluid physical properties are changed, heat transfer coefficient is also have change So the heat transfer coefficient, but the impact is not big.
