The invention provides a swirling air flow-type and wet flue gas desulfurization technique and a spraying tower thereof. The technique guides flue gases to enter tangentially from the upper part of a spraying tower shell; the flue gases swirl inside the spraying tower shell and leave tangentially from the lower part of the spraying tower shell; at the same time, limestone grout is sprayed upward and fog drips of the grout firstly touch the downward-swirling flue gas reverse flow, and then fall back owing to the effect of self-weight and drag force of the flue gas and then touch the forward flow of the flue gas, thus sulfur dioxide in the flue gases is absorbed owing to the quick chemical reaction with limestone grout fog drops. The spraying tower comprises a spraying tower shell; the spraying tower shell is provided with tangentially arranged flue gas inlet and outlet channels; a spraying device for spraying absorbing agents upwards is arranged between the flue gas inlet and outlet channels; a central tank is arranged in the center of the spraying tower shell; a flue gas guide plate showing a spiral descent structure is arranged on the central tank; a defroster is arranged in the flue gas inlet and outlet channels of the spraying tower shell. The desulfurization efficiency thereof is high, investment is small, and operation is safe and reliable.

The invention discloses a laminated secondary battery based on cross-stacking and a preparation method thereof. The disclosed secondary battery is formed by cross-stacking unipolar groups and positive and negative unipolar sheets, and the unipolar groups are integrally formed. It effectively reduces the situation that the performance of the battery does not meet the requirements due to poor positive and negative unipolar sheets. Manufacturing laminated secondary batteries according to the preparation method provided by the present invention can effectively solve existing problems. The monopole group and pole pieces are alternately stacked. The production process of the monopole group and pole pieces is relatively simple. During this process, defective products can be effectively screened out in advance, and the frequency of rework can be significantly reduced. Moreover, the invention adopts the method of stacking the monopole group and the monopole sheet, which can effectively reduce the initial investment cost of the monopole group and the monopole sheet manufacturing equipment.

The invention relates to a vertical environment-friendly boiler for triple dedusting burning wood and biological particle fuel in a boiler, belonging to heating technology. The invention is used for burning wood and biological particles to obtain hot water or steam, and overcomes the defects of black smoke emission, low thermal efficiency, and the like of the similar traditional boilers. The boiler comprises a wind chamber, a fire grate, a carbon powder and gas burning hearth, a first wind inlet, a secondary wind inlet, and a heat exchanger above the hearth. The boiler is characterized in that the hearth is provided with a porous boiler crown of an inclined air vent; the upper end of an inner liner is provided with a smoke blocking wall; a downward screwed smoke tube is arranged between the wall of the inner liner and a lower end socket; an upward screwed smoke tube penetrates through an upper closing plate and a lower closing plate; and a heat exchanger seat of a smoke diversion dedusting chamber in the shape of a ring cavity is arranged on the circumference of the lower end of the heat exchanger. The invention has the advantages of sufficient burning of carbon powders, sufficient gasification and high thermal efficiency. Smoke is dedusted three times in the boiler, and the exhausted smoke has low dust capacity. The invention can be manufactured in a split mode, and is convenient to transport. The tonnage can be greatly increased.
