Abstract
The utility model discloses an improved air heat accumulation tank, which comprises a tank body with a lower opening, wherein a dust stratification area is arranged at the lower opening of the tank body; an air inlet is formed in the upper half part of the front surface of the dust stratification area; a grating plate is arranged at the upper part of the air inlet, and is placed on a support frame in the tank body; a honeycomb type heat accumulation body is arranged above the grating plate; an air outlet is formed in the upper part of the tank body. According to the improved air heat accumulation tank, an entering mode of air is changed from an original back-inlet front-outlet mode into a bottom-inlet top-outlet mode, and air is perpendicularly circulated, so that most of dust in flue gas can fall into the dust stratification area at the bottom of the heat accumulation tank under the action of draft disturbance of an induced draft fan and natural gravity, jamming conditions are obviously improved, air in the heat accumulation tank can be kept better circulated for a long time, the heating quality and the heating capability are ensured, and the normal running of a heating furnace is facilitated; high heat exchange efficiency and good energy-saving effects of the honeycomb type heat accumulation body are ensured, and the running cost of the heating furnace is greatly lowered; the shutdown maintenance time is reduced, the replacement cycle is prolonged, the production efficiency is effectively improved, and smooth production is facilitated.
Description
Technical field
The invention belongs to mechanical equipment technical field, be specifically related to a kind of modified air heat storage tank.
Background technology
Honeycomb regenerator formula burner is because energy-saving effect is obvious, on the heating furnace of smelter, application was more and more extensive in the last few years, it combines heat accumulating type technology and traditional burner, make heat-accumulating burner there is the function of preheated air (coal gas), tissue burning and smoke evacuation, honeycomb heat accumulation body is owing to having the advantages such as specific area is large, floor space is little, heat storage capacity is strong, be applied in heat-accumulating burner, as the carrier of heat-shift between flue gas and air (coal gas), make the compact conformation of recuperative heater, and can obtain maximum heat transfer effect.
But in the use procedure of heating furnace; the phenomenon that often there will be honeycomb heat accumulation body to stop up; cause sky (cigarette) air-flow circulation passage to diminish; increase circulating resistance; cause heat exchange effect variation and preheating of air temperature to reduce; when serious, can hinder air and enter the discharge of stove and flue gas, occur that furnace temperature reduces, the anomalies such as furnace pressure rising.
The reason resulting in blockage roughly has five: dust sticks tar bonding, the honeycomb regenerator fragmentation body of in the high temperature adsorption, high heating value gas of accumulations, iron scale powder, separating out and pushes and the melting of honeycomb heat accumulation body surface high-temp in flue gas.It is the main cause that we in use run into that the interior dust of flue gas wherein sticks accumulation.
The air heat storage tank of the honeycomb regenerator formula burner using in the past, all to adopt the form going out before laggard, as Fig. 4, air (flue gas) is horizontal direction circulation, be that air enters from heat storage tank rear portion air inlet 5, by honeycomb heat accumulation body 8 preheatings, then enter burner from anterior air outlet 6, and flue gas enters from air outlet 6, after honeycomb heat accumulation body 8 release heat, discharge from heat storage tank rear portion air inlet 5 again, adopt the shortcoming of this form maximum, be exactly that the dust of taking out of in flue gas discharge process can stick in the hexagon ring and space, rear portion that is deposited in honeycomb heat accumulation body, although there is floater guide block 9, time is not grown and also can result in blockage, have influence on the normal use of heat-accumulating burner, and then have influence on the production capacity of heating furnace, the aspect such as heating quality and energy consumption, according to statistics, aspect energy consumption, honeycomb regenerator formula burner fractional energy savings can be dropped to below 20% by 50% original left and right, at this moment must stop production heat storage tank is opened and inspect, clear up and change honeycomb heat accumulation body, general opens and inspect, replacement cycle is about 6 months.
Summary of the invention
For addressing the above problem, the invention discloses a kind of modified air heat storage tank, change air mode of entrance, the original pattern going out before laggard is changed into the pattern of bottom in and top out, under air-introduced machine draft disturbance and natural gravity effect, most of dust in flue gas can fall into the dust stratification district of heat storage tank bottom, and stopping state is clearly better.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of modified air heat storage tank, comprise the casing of lower opening, it is characterized in that: described casing lower opening Chu You dust stratification district, the dust stratification district front first half has air inlet, air inlet top is provided with flase floor, flase floor is placed on the support frame of box house, and flase floor top is provided with honeycomb type heat storage, and casing side top has air outlet.
As a modification of the present invention, described box back surface is provided with access hole.
The invention has the beneficial effects as follows:
A kind of modified air heat storage tank of the present invention, change air mode of entrance, the original pattern going out before laggard is changed into the pattern of bottom in and top out, air (flue gas) is vertical direction circulation, be that air enters from heat storage tank bottom, by honeycomb heat accumulation body preheating, then enter burner from top, flue gas enters from heat storage tank top, after honeycomb heat accumulation body release heat, discharge from heat storage tank bottom again, such benefit is exactly, under air-introduced machine draft disturbance and natural gravity effect, most of dust in flue gas can fall into the dust stratification district of heat storage tank bottom, stopping state is clearly better, make sky (cigarette) the air-flow general character in heat storage tank keep for a long time better, heating quality and heating efficiency are guaranteed, be conducive to the normal operation of heating furnace, heat exchange efficiency and energy-saving effect that honeycomb heat accumulation body is good are guaranteed, the operating cost of greatly having saved heating furnace, reduced stopping production maintenance time, extended the replacement cycle, effectively improved production operational availability, what be conducive to produce carries out smoothly.
