Abstract
The utility model relates to a bag-type dust remover provided with a cooling device. The bag-type dust remover comprises a bag-type dust remover body, a temperature sensor, a cooling device, a cooling water pump, a cooling tower and an automatic control system, wherein the temperature sensor is mounted in front of the cooling device; the cooling device is mounted in front of the bag-type dust remover body; an inlet of the cooling water pump is connected with the cooling tower, and an outlet of the cooling water pump is connected with an inlet of the cooling device; and an outlet of the cooling device is connected with a cooling tower. The temperature sensor detects the temperature of smoke before the smoke enters the cooling device; when the smoke temperature is higher than the preset critical highest smoke temperature, the cooling water pump is started, and the cooling device is started; and when the smoke temperature is lower than a preset critical lowest smoke temperature, the cooling water pump is stopped, and the cooling device stops operating.
Description
Technical field
The utility model relates to a kind of sack cleaner with heat sink, is specifically related to a kind of smoke dust-removing equipment.
Background technology
The northern area of China, used the coal-burning boiler heating winter in a large number at present.Contain a large amount of following particles of 2.5 μ m in the flue dust of the fossil-fuel-fired discharge such as coal.For reducing the PM2.5 exhaust emission, country sets up average annual, the average daily concentration limit of PM2.5 in the original basic monitoring project of GB3095-2012 " ambient air quality ".Sack cleaner dedusting particle diameter is the above particle of 0.1 μ m, and its efficiency of dust collection can reach 99.9%, and smoke dust discharge concentration can be controlled at 50mg/Nm
3in, can adapt to the requirement of PM2.5, and dust settling pocket technique is perfect and ripe gradually, will more and more be used widely.
But during boiler operatiopn, uncertain factor is more, sometimes the flue gas of boiler emission can surpass the temperature range of expection, may surpass the limiting temperature that filter bag is used, thereby causes the cloth bag damage.The increasing device maintenance capacity, reduce efficiency of dust collection, reduces capacity utilization.
Summary of the invention
The utility model is in order to make up the prior art deficiency, provides a kind of cigarette temperature that can adapt to raise suddenly, and efficiency of dust collection is high, a little repair, cloth bag long service life, the sack cleaner with heat sink that capacity utilization is high.
The technical scheme in the invention for solving the above technical problem is described as follows:
A kind of sack cleaner with heat sink, comprise sack cleaner body, temperature sensor, heat sink, cooling water pump, cooling tower, automatic control system, it is characterized in that: described sack cleaner connects heat sink, cooling tower, cooling water pump successively, before temperature sensor is installed on heat sink; Described sack cleaner body front end is equipped with heat sink, can reduce in real time the flue-gas temperature that enters sack cleaner.
Utilize the utility model to comprise the steps: 1 with the method for the sack cleaner of heat sink) temperature sensor detection flue-gas temperature; 2) set the critical-temperature (high temperature, low temperature) of On/Off heat sink; 3) when flue-gas temperature during higher than critical maximum temperature cooling water pump open; 4) when flue-gas temperature during lower than critical minimum temperature cooling water pump close; 5) cooling water pump is controlled automatically by automatic control system.
The utility model makes up the conventional cloth bag deduster in the flue gas ash removal process, because the flue-gas temperature cloth bag that rising causes suddenly damages; 30 ℃ of maximum cooling extents.The utlity model has the characteristics that efficiency of dust collection is high, the maintenance of equipment amount is little.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the schematic diagram of the utility model with the sack cleaner of heat sink.
1-sack cleaner body in figure, 2-temperature sensor, 3-heat sink, 4-cooling water pump, 5-cooling tower, 6-automatic control system
The specific embodiment
In conjunction with above-mentioned accompanying drawing, the utility model is described in detail.
Implementation step: method 1) temperature sensor detects flue-gas temperature; 2) set the critical-temperature open/close heat sink (high temperature is set as 180 ℃, low temperature and is set as 120 ℃); 3), when 180 ℃ of flue-gas temperatures, cooling water pump is opened; 4) when flue-gas temperature during lower than 120 ℃ cooling water pump close; 5) cooling water pump is controlled automatically by automatic control system.
Implementation step: method two 1) temperature sensor detects flue-gas temperature; 2) set the critical-temperature open/close heat sink (high temperature is set as 160 ℃, low temperature and is set as 110 ℃); 3) when 180 ℃ of flue-gas temperatures, cooling water pump is opened; 4) when flue-gas temperature during lower than 120 ℃ cooling water pump close; 5) cooling water pump is controlled automatically by automatic control system.
It should be noted that above-mentioned example is only for exemplary, those skilled in the art can set the highest and minimum critical-temperature according to the temperature resistant range of cloth bag, and the change of these temperature all is included in protection domain of the present utility model.
Claims (2)
