Abstract
The utility model relates to a high-temperature dust remover with temperature difference compensation devices, which solves the technical problem that deformation is generated under a high-temperature environment because of thermal expansion and cold shrinkage so as to further cause the damage of equipment. The utility model adopts the technical scheme that the high-temperature dust remover is a dust remover which adapts to the long-term work at the environmental temperature of 300 DEG C -800 DEG C, and the temperature difference compensation devices with the function of compensating thermal expansion and cold shrinkage are additionally arranged on the connecting and positioning positions of a raw gas inlet, a purified gas outlet, a reverse blowing air port, an ash falling port and a casing of the high-temperature dust remover, the connecting position of each chamber inside the casing, the position of the waist part of the casing and the positioning position of a tubeplate in the casing. The temperature difference compensation devices are positioned and connected by a matched welding material. The utility model has the advantages that the utility model has very good compensation effect to large tension generated by the thermal expansion and the cold shrinkage, the service life of equipment is prolonged, the effects of heat preservation and heat insulation of the equipment and the outside are obvious, and the potential safety hazards of the equipment are reduced.
Description
Technical field
The utility model belongs to the manufacturing field of industrial dedusting equipment, specifically is to be used for producing the deduster that raw coke oven gas is administered, particularly a kind of hot precipitator with difference variation process to producing.
Background technology
At present a lot of fields all relate to the problem of utilizing of coal gas that burning is generated in the industrial production, prior art generally all adopts pocket type or electric dust-removing process, its shortcoming is that operating temperature is lower, the heat energy of coal gas very large part all is wasted, can not well utilize, so people more and more pay close attention to the utilization to hot precipitator.
The advantage of hot precipitator is chemical energy and the physical energy that generates the high temperature purified gas all can be used, and avoids the waste of the energy.But hinder for still existing numerous camphor trees at present in the production of hot precipitator and the preparation, especially under the hot environment because the deformation that produces of expanding with heat and contract with cold causes problems such as device damage, also be difficult at present solve.Therefore hindered further developing of high-temperature dust removal technology.
Summary of the invention
Produce the technical problem that deformation further causes equipment damage for solving under hot environment owing to expand with heat and contract with cold, the utility model has designed a kind of hot precipitator with temperature difference compensation device, connecting portion in hot precipitator is set up the temperature difference compensation device, can be good at compensating the huge deformation of expanding with heat and contract with cold and bringing in the course of the work.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of hot precipitator with temperature difference compensation device, this hot precipitator is the deduster that adapts to long-term work under 800 ℃ of-300 ℃ of environment temperatures, in its raw coke oven gas import, the purified gas outlet, the blowback air port, the position point that is connected of ash port and housing, housing) connecting portion of inner each locellus, the waist position of housing, and on the location of card in housing, all have additional the temperature difference compensation device with the compensating action that expands with heat and contract with cold, this temperature difference compensation device positions by supporting securing member or wlding and is connected.
The beneficial effects of the utility model are that the huge deformation power that produces of expanding with heat and contract with cold is had good compensation effect, have prolonged the service life of equipment, and equipment is obvious with extraneous insulation, effect of heat insulation, has reduced the potential safety hazard of equipment.
