Description
Technical field
The utility model relates to industrial cycle cooling technology, is specially a kind of enclosed cooling recirculation system for waste calcining facility.
Background technology
High-temperature service in hazardous waste burn system comprises rotary kiln feed hopper, kiln hood and dual firing chamber's slag scraper.Feed hopper is positioned at the front end of rotary kiln, and slag scraper is positioned at the bottom of dual firing chamber.In burning line running, the temperature of rotary kiln is 850 DEG C, the temperatures as high of dual firing chamber 1000 DEG C, and feed hopper and slag scraper are located to run at high operating temperatures for a long time, and its material creep can occur, and the life-span can shorten greatly.Due to the radiant heat of incinerator, kiln hood and feed well likely produce thermal deformation, overheated in order to prevent, blanking groove in the radiation areas being exposed to rotary kiln, kiln hood part, major part laying fireproof bricks, with the place of refractory brick solar heat protection, can not be designed to the double-decker being with water-cooling jacket, cooled by cooling water recirculation system, prevent the distortion of kiln hood and feed well.
Therefore under such conditions, need to adopt circulating cooling system to carry out cooling protection to feed hopper, kiln hood and slag scraper.
Mostly open cooling tower is adopted in current circulating cooling system, open cooling tower be by by recirculated water with spray pattern, spray is on the filler of glass fibre, heat exchange is carried out with direct contact of air by water, blower fan is utilized to drive airflow circulating in tower, by with water heat exchange after thermal current take out of, thus reach cooling object.But there is certain shortcoming in the existing open cooling tower for dangerous waste incineration device:
1, accurate not to the control of temperature;
2, need the underground tank excavating 1-2 20 cubes, due to water drop and open lift loss, power consumption is large;
3, due to the recirculated water windage loss of open system and evaporation loss large, so rate of water make-up is large in running, water consumption is high;
4, because open cooling tower needs pond, floor space is comparatively large, installs also cumbersome;
5, open cooling tower directly contacts with air, and easily contaminated, water quality easily degenerates, and influential system runs.
Summary of the invention
The purpose of this utility model is to provide a kind of enclosed cooling recirculation system for waste calcining facility, and automaticity is high, dependable performance, operating cost are low, and can avoid water pollution.
Enclosed cooling recirculation system for waste calcining facility described in the utility model, comprise closed cooling tower, described closed cooling tower comprises blower fan, spray equipment, cooling coil and water leg, described blower fan is located at closed cooling tower top, water leg is positioned at below cooling coil, described water leg is communicated with spray equipment by coolant circulation pump, the delivery port of described cooling coil is communicated with the water inlet of high-temperature service by inlet pipeline, the delivery port of described high-temperature service is communicated with the water inlet of cooling coil through hot water circulating pump by water return pipeline, described system also comprises temperature measuring set and controller, described temperature measuring set is located on the delivery port of cooling coil, described controller and described temperature measuring set, coolant circulation pump is connected with blower fan.
Further, soft water water source is communicated with described water return pipeline by small pump.
Further, produce water water source to be communicated with described inlet pipeline by accident water pump.
Cooling recirculation system described in the utility model has the following advantages:
1, owing to being closed cycle, it can ensure that water quality is not contaminated, system uses soft water, can make feed hopper, kiln hood water-cooling ring, slag scraper and pipeline non-scaling, do not pollute, decrease corrosion, extends the service life of feed hopper, kiln hood water-cooling ring and dual firing chamber's slag scraper;
2, cooling system is closed circulation, and soft water does not almost consume, and can save a large amount of soft water;
3, closed cooling tower is provided with Based Intelligent Control, comes controlled cooling model circulating pump and blower fan according to operating mode start and stop, serve energy-saving and cost-reducing effect by controller, can the precision of strict temperature control;
4, closed cooling tower does not need independently pond, and occupation of land space is less, installs and facilitates yet.
The operating cost summarizing this cooling recirculation system is lower, meets energy-saving and cost-reducing requirement, adopts soft water circulation, makes pipeline and equipment non-scaling, do not pollute, decrease corrosion, extend the service life of equipment and pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
The enclosed cooling recirculation system for waste calcining facility as shown in Figure 1, described closed cooling tower 1 comprises blower fan 11, spray equipment 12, cooling coil 13 and water leg 14.
Described blower fan 11 is located at closed cooling tower top, and water leg 14 is positioned at below cooling coil 13, and described water leg 14 is communicated with spray equipment 12 by coolant circulation pump 2.During work, water is sprayed on damp and hot cooling coil tube wall by spray equipment and forms moisture film by coolant circulation pump, absorbs amount of heat by evaporation, part shower water becomes steam, taken away by air, do not dropped in water leg by the water droplet evaporated, for recycling.
The delivery port of described cooling coil 13 is communicated with by the water inlet of inlet pipeline with high-temperature service 3, the delivery port of described high-temperature service 3 is communicated with through the water inlet of hot water circulating pump 4 with cooling coil 13 by water return pipeline, and in the present embodiment, high-temperature service is feed hopper, kiln hood water-cooling ring and slag scraper.
Described system also comprises temperature measuring set 6 and controller 5, and described temperature measuring set 6 is located on the delivery port of cooling coil 13, and described controller 5 is connected with described temperature measuring set 6, coolant circulation pump 2 and blower fan 11.
Described controller receives the outlet water temperature of the closed cooling tower measured by temperature measuring set, and judges with presetting temperature range, thus the operation of controlled cooling model circulating pump and blower fan.
Soft water water source 7 is communicated with described water return pipeline, to system water supplement by small pump 8.Produce water water source 9 to be communicated with described inlet pipeline by accident water pump 10.
The workflow of above-mentioned enclosed cooling recirculation system is: soft water squeezes into system by small pump, after converging with backwater, closed cooling tower is squeezed into by hot water circulating pump, after heat radiation, soft water return water temperature is down to 40 DEG C from 70 DEG C, then enter high-temperature service, after high-temperature medium heat exchange, temperature rises to 70 DEG C, each stock soft water returns again closed cooling tower cooling through water return pipeline, so circulates.When causing closed cooling tower out of service when having an accident, filling into industrial water by accident water pump, maintaining system cloud gray model temporarily.
