Abstract
The utility model discloses an energy saving structure of coal gas generating equipment, which comprises a coal gas producer. A coal gas outlet on the coal gas producer is communicated with the air inlet of a dust catcher, and the air outlet end of the dust catcher is connected with a pipeline and communicated with a heat exchanger, a washing tower, an electrical light oil device and a pressurization fan in sequence; thereby the heat of the hot coal gas generated from the dust catcher is reduced after passing through the heat exchanger in the pipeline, and cooling effect is performed, the exchanged heat can have other purposes, such as water heating and steam producing, and the purpose of saving energy and reducing emissions is reached.
Description
Technical field
The utility model relates to a kind of energy-saving structure, particularly a kind of energy-saving structure of coal gas generation equipment.
Background technology
At present, common coal gas generation equipment is: adopt producer gas generator to produce coal gas earlier, passing through its gas exit (two-stage gas-fired furnace is the hypomere gas exit) then delivers in the fly-ash separator except that dust by pipeline, and then it is cooled off with air cooler, cooled coal gas is delivered to washing tower, electric fishing light oil device successively by pipeline, delivers to burner through the coal gas after repeatedly purifying by booster fan; And coal gas is one necessary process through air cooler, and cooled coal gas can be avoided superheated coal gas to produce a large amount of steam when washing and influence coal gas purity.But, be that the heat energy in the coal gas directly is dispersed in the atmosphere in air-cooled process.Whether these thermal energy collectings can be got up and utilize once more, reach the purpose of energy-saving and emission-reduction, become the problem of the required solution of people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure and energy-saving structure of coal gas generation equipment with advantage of energy-saving and emission-reduction.
The technical scheme that its technical problem that solves the utility model adopts is:
The energy-saving structure of coal gas generation equipment, comprise producer gas generator, described producer gas generator is communicated with the gas exit on it by pipeline with the inlet mouth of fly-ash separator, described fly-ash separator air outlet end is connected with pipeline and is communicated with heat exchanger, washing tower, electric fishing light oil device, booster fan successively.
In the utility model, described pipeline passes heat exchanger again through behind the booster fan.
The beneficial effects of the utility model are: since the fly-ash separator exit end heating gas in the utility model by behind the heat exchanger successively with washing tower, electric fishing light oil device, booster fan UNICOM; The heating gas that comes out from fly-ash separator has reduced temperature behind over-heat-exchanger like this, has played cooling effect.And heat exchanger is given cooled coal gas after purifying with the thermal power transfer that displaces, makes it to become purified heating gas.The heat energy that displaces also can be made other purposes, as adds hot water, produces steam etc., has reached the purpose of energy-saving and emission-reduction.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the energy-saving structure of coal gas generation equipment, comprise producer gas generator 1, described producer gas generator 1 is communicated with the gas exit on it (two-stage gas-fired furnace is the hypomere gas exit) by pipeline with the inlet mouth of fly-ash separator 2, described fly-ash separator 2 air outlet ends are connected with pipeline and are communicated with heat exchanger 3, washing tower 4, electric fishing light oil device 5, booster fan 6 successively.
Since the fly-ash separator 2 exit end heating gas in the utility model by behind the heat exchanger 3 successively with washing tower 4, electric fishing light oil device 5, booster fan 6 UNICOMs; The heating gas that comes out from fly-ash separator 2 has reduced temperature behind over-heat-exchanger 3 like this, has played cooling effect.The heat energy that displaces also can be made other purposes, as adds hot water, produces steam etc., has reached the purpose of energy-saving and emission-reduction.
In the utility model, purified cooled coal gas after coming out from electric fishing light oil device 5 through behind the booster fan 6 again by heat exchanger 3, can make cooled coal gas once more from heat exchanger 3 processes like this, send again after the heat heating that is displaced by heat exchanger 3, some equipment (as ceramic kiln, aluminium stove, calcining furnace, metallurgical equipment etc.) that need the coal gas heating have been played good energy-saving effect.
The utility model is rational in infrastructure and have the advantage of energy-saving and emission-reduction, is a kind of energy-saving structure that is widely used on the coal gas generation equipment.
Claims (2)
