Abstract
The utility model discloses a heat exchanger of the crystal decomposing slot for the product of alumina. The heat exchanger comprises a heat exchange unit and a connection piece of the heat exchange unit. The heat exchange unit is a cavity body in the hollowed structure welded by two or more heat exchange sheets, and at least two through-pores are provided on the heat exchange unit. The connection piece of the heat exchange unit is a tubular element connecting at least two heat exchange units together through the through-pore. Therefore, the at least two heat exchange unit communicate with each other, and every two heat exchange units are connected by the through-pore. The cold water can be circulated inside the heat exchange device. The main body of the heat exchange device is in the water phase in the single hollowed board type structure, the phase of the material is in the open type, so that no problem of deposition occurs. Scaling is unlikely to be formed for the main body of the apparatus because of heat exchanger is immersed under the liquid surface in the groove, so that the life cycle can be prolonged. The operation of the material in the material phase is implemented by the self-driving in the groove, so that other power for driving is not needed to be provided.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially relates to a kind of heat exchanger that material and water in the aluminum oxide production process decomposition of crystal seed groove is carried out the heat exchange cooling that is applicable to.
Background technology
At present, in aluminum oxide production process, the cooling of material (mixing material that solids content is higher) mainly adopts equipment such as broad passage plate, spiral plate type to carry out cold and hot thermal energy exchange mutually with water in the decomposition of crystal seed groove, to reduce material temperature in the seed precipitation tank, reaches the requirement of technology controlling and process.But these equipment material are the totally-enclosed structure with water (heat, mutually cold) mutually, its side pole by the material phase of material (liquid that solids content is higher) easily forms fouling or buildup, cause the material handling capacity to reduce on the one hand, heat transfer efficiency is reduced, the cooling ability declines to a great extent.Simultaneously, because the equipment heat exchange seals mutually, the fouling of its formation or buildup are difficult to remove, or can't repair after the equipment attrition leakage, cause scrapping of whole equipment the most at last.And these equipment need adopt the pump class to carry at the heat transfer process material, consumed power, and energy consumption is higher, and the installation form of pump often adopts installs (submerged pump) below the liquid level in groove, and equipment fault is many, maintenance, difficult in maintenance.Above problem causes equipment such as the material cooling is adopted in the present decomposition of crystal seed groove broad passage plate, spiral plate type, investment is high, fault is many, running cost is high, the maintenance difficulty greatly, fluctuation of service, cooling-down effect is bad, thereby has influence on control of process condition.
Summary of the invention
In view of this, the purpose of this utility model is exactly the deficiency at above-mentioned existence, and it is open type that a kind of material phase structure is provided, and is easy to clear up fouling, and the material heat transfer process does not need dedicated transport equipment, maintenance, heat exchanger apparatus easy to maintenance.
Above-mentioned purpose realizes by following proposal:
A kind of decomposition of crystal seed groove heat exchanger that is used for alumina producing is characterized in that described heat exchanger comprises:
Heat exchange unit, described heat exchange unit for by 2 or more the polylith heat exchange plate be welded into cavity with hollow structure, have at least 2 through holes on the described heat exchange element;
The heat exchange unit connector, described heat exchange unit connector is a tube element, it links together 2 described heat exchange units by described through hole at least, make at least 2 described heat exchange units be communicated with, and per two described heat exchange units is connected by at least 2 heat exchange unit connectors;
Pipe fitting, at least 2 described pipe fittings are connected on 2 through holes of heat exchange unit of described heat exchanger one end at least;
Closeouts, described at least 2 closeouts are connected on 2 through holes of heat exchange unit of the described heat exchanger other end at least, and described through hole is blocked.
Heat exchanger according to above-mentioned is characterized in that, described heat exchange plate is ordinary steel plate or stainless steel plate, and described heat exchange unit is a hollow cavity.
Heat exchanger according to above-mentioned is characterized in that, described heat exchange unit connector is made by common steel or stainless steel.
Heat exchanger according to above-mentioned is characterized in that, described heat exchanger unit connector or closeouts are connected with the mode of described heat exchange unit by welding or screw threads for fastening.
This heat exchanger main body is single water, and material is open plank frame mutually, so there is not deposition problems in material.And because heat exchanger is immersed in below the interior liquid level of groove, apparatus body is less scaling, can prolong life cycle.The operation of material phase materials realizes by means of carrying in the groove to stir, does not need to provide other power again.Simultaneously, behind the long-play, when heat exchanger need clean or leak maintenance, hang out in groove, material is highly susceptible to adopting physical method or chemical method directly to handle more completely mutually, and the inner water of heat exchanger adopts soak cleaning also very convenient, and maintenance also is easy to.The utility model is simple in structure, volume is dexterous, weight of equipment is little, small investment, easily installation, easy to clean, easily overhaul, can multi-platform combinedly use, the heat exchange efficiency height.
Description of drawings
Fig. 1 is the profile of heat exchanger of the present utility model;
Fig. 2 is the right view of heat exchanger shown in Figure 1.
The specific embodiment
Referring to Fig. 1, a kind of heat exchanger comprises heat exchange unit 1, heat exchange unit connector 2, water inlet pipe 3, outlet pipe 4 and closeouts 5, serve as reasons heat exchange plate that at least 2 ordinary steel plates or stainless steel plate make of heat exchange unit 1 is welded into the cavity with hollow structure and (is rectangle shown in Fig. 1, also can be other shapes), have at least 2 through holes (shown in Fig. 1 is 2 through holes) on the heat exchange unit 1.The tube element that heat exchange unit connector 2 is made for common steel or stainless steel, it links together at least 2 heat exchange units 1 (Figure 1 shows that 5 heat exchange units, can select the quantity of heat exchange unit as required).On the heat exchange unit 1 of heat exchanger right-hand member, be connected with water inlet pipe 3 and outlet pipe 4, be connected with closeouts 5 at the other end.Connector 2, water inlet pipe 3, outlet pipe 4 and closeouts 5 all can also be connected with heat exchange unit by the mode that is threaded or welds.
The inner space of heat exchanger constitutes the runner 6 of water, and cold water circulates therein, and the space between heat exchange unit 1 outside constitutes the material phase passage 7 of the material of will lowering the temperature, and material flows at this passage 7.
Referring to Fig. 2, the pipe fitting of upside and downside pipe fitting constitute water inlet pipe 3 and outlet pipe 4.
