Description

UTILIZATION OF VESIDUAL HEAT IN cyclone separator
Technical field
The present invention relates to a kind of cyclone separator, specifically, a kind of UTILIZATION OF VESIDUAL HEAT IN cyclone separator relate to.
Background technology
The industrial development of China enters a new stage at present, and environmental problem such as air pollution, water pollution are increasingly It is prominent, all badly influence the normal life of people and healthy, increasingly paid close attention to by people.Industrial processes In can produce a large amount of environmentally harmful organic gas.In this case, it is necessary to increase the research and development power of VOCs treatment technology Degree, the harm to atmospheric environment is reduced by improving exhaust gas treatment technology.In chemical industry, solid and gas separation is often used Device, for removing the impurity such as the dust granules in gas, cyclone separator is most widely used, but monistic whirlwind point High temperature problem can not be solved from device, causes hot gas to be discharged into air, causes thermal pollution.
The method that current enterprise generally uses has two kinds, and one is first to carry out waste heat recovery, then carries out dust removal process;Two It is first to carry out dust removal process, waste heat recovery is carried out afterwards.The drawbacks of both of which has certain:In first method flue gas Flue dust can block the exhaust gases passes of heat exchanger, over time, and the high-temperature smoke being attached on heat-transfer surface will increase the heat of heat-transfer surface Resistance, thus heat exchange efficiency reduction, influence the heat transfer effect of equipment;Also, for the waste heat recovery of high-temperature gas, easily cause heat Stress corrosion.If using second method, carrying out that during dedusting the temperature of flue gas can be reduced in cleaner, so that Produce certain waste heat loss.
Further, since the viscosity of high-temperature flue gas is more than low-temperature flue gas, so drag losses increase of the flue gas in deduster, Need to consume more power, cause the waste of the energy.
In order to solve the problem of above is present, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, so that it is high, integrated to provide a kind of design science, heat exchange efficiency Degree is high, the UTILIZATION OF VESIDUAL HEAT IN cyclone separator of energy-conserving and environment-protective.
To achieve these goals, the technical solution adopted in the present invention is:A kind of UTILIZATION OF VESIDUAL HEAT IN cyclone separator, it is wrapped Include housing, the dusty gas entrance located at housing sidepiece, air inlet distributor, the ash discharging hole located at housing lower end and located at housing top One group of helical pipe is set in the net gas outlet in portion, the housing, and the upper end of helical pipe described in one group is sealed to be contained described in connection Dirt gas access, the lower end sealing connection ash discharging hole of helical pipe described in one group, the ash discharging hole is sealed by riser The net gas outlet is connected, the shell side space of the ash discharging hole and the housing completely cuts off, the upper side and lower side difference of the housing Open up the heat transferring medium entrance for connecting the shell side space and heat transferring medium outlet.
Described on base, inwall of the helical pipe along the housing described in one group spirals settings, helical pipe described in one group with Stayed between the inwall of the housing and set gap.
Described on base, it also includes at least one set of inside spin pipeline, and the upper end connection of inside spin pipeline described in every group is described Dusty gas entrance, the lower end of inside spin pipeline described in every group is connected to be stayed between the ash discharging hole, inside spin pipeline described in each group There is gap, gap is left between outermost one group of inside spin pipeline and the helical pipe.
Described on base, the ash discharging hole includes being located at the horizontal baffle of the housing lower end and is opened in the horizontal baffle The upper opening for being used to install the riser, the lower end of inside spin pipeline is equal described in the lower end of helical pipe described in one group and each group It is located on the dividing plate.
Described on base, the lower end of inside spin pipeline described in the lower end of helical pipe described in one group and each group is located in described On side wall below riser.
It is described on base, fin is set on the outer wall of inside spin pipeline described in helical pipe described in one group and each group.
The present invention is compared with the prior art with prominent substantive distinguishing features and significantly progressive, specifically, tool of the invention Have the advantage that:
1st, the integrated heat exchange function in cyclone separator, high-temperature dusty gas, which enters, realizes that solid and gas is separated in helix tube, together When, high-temperature gas is flowed in helix tube high speed, and heat is concentrated under high-speed screw motion to tube wall, then passes through tube wall and shell The heat transferring medium of journey is exchanged heat, dusty gas high speed rotational flow in helix tube, is effectively thinned flow of fluid border Layer, reduces thermal resistance, improves heat exchange efficiency, it is to avoid the waste heat losing issue of separated processing.In addition, helical pipe is less Diameter can farthest increase the heat exchange area of high-temperature gas and shell side heat transferring medium, and further improving heat exchanging efficiency is kept away Exempt from the waste of heat.
2nd, increase inside spin pipeline, enough helical pipes are arranged in housing, one is the flow for ensureing gas, and two be to protect Demonstrate,prove the abundant contact of gas and heat transferring medium, further improving heat exchanging efficiency.
3rd, it because helical pipe is integrated in housing, can be transformed, be transformed based on existing whirlwind heat exchanger Cost is low, meanwhile, volume keeps constant, and integrated level is improved, and is easy to carry out supporting install based on existing equipment.
4th, the heat that high-temperature gas is carried is taken out of in time by heat transferring medium, effectively reduces the wind that high temperature stress corrosion is brought Danger.
It has the advantages that design science, heat exchange efficiency are high, integrated level is high, energy-conserving and environment-protective.
