Description
Technical Field
The utility model relates to the technical field of washing devices, in particular to a flue gas washing tower.
Background
The flue gas washing tower is mainly used for treating flue gas from a power plant, and has the main function of washing and cooling. Because the flue gas that comes from the power plant contains more dust, and is dirty relatively, and the temperature is around 110 ℃, the scrubbing tower washs the dust of the flue gas that gets into through spraying, reduces the temperature of flue gas to within 50 ℃ simultaneously through cooling water, and qualified flue gas can get into the following compressor and compress, if flue gas temperature is too high, can influence the performance of compressor. In popular terms, flue gas scrubber is used to provide acceptable flue gas for use in compressors.
The flue gas washing tower is in reverse contact with flue gas entering from the lower part of the tower by spraying washing liquid from the top of the tower, so that fine particles in the flue gas are settled to the bottom of the tower along with the washing liquid. The lower part in the existing washing tower is provided with a liquid level monitor which is interlocked with a liquid delivery pump. The used washing liquid is gathered at the bottom of the tower, and when the liquid level reaches the position of the liquid level monitor, the pump automatically transfers the washing liquid out of the washing tower. Such an arrangement is convenient, but due to the use of such precision instruments as a liquid level monitor, once the instrument fails or fails, the liquid level in the tower will rise, and the risk of liquid backflow or overflow occurs.
Disclosure of Invention
The utility model provides a flue gas scrubbing tower aiming at the problems existing in the existing flue gas scrubbing tower so as to solve the problems.
A flue gas washing tower, which comprises a tower body and a balance tank; the top of the tower body is provided with a liquid inlet pipe, and one end of the liquid inlet pipe extending into the tower body is provided with a spray header; an air inlet pipe is arranged at the lower part of the tower body; an air outlet pipe is arranged at the upper part of the tower body; the bottom of the tower body is connected with the bottom of the balance tank through a pipeline; a liquid outlet pipe is arranged at the upper part of the balance tank; the top of the balance tank is provided with a pressure release valve; the height of the liquid outlet pipe is lower than that of the air inlet pipe.
Further, a porous disc is arranged in the tower body. Thus, the uniformity of the gas to be purified in the tower is ensured, the contact between the gas and the washing liquid is ensured, and the purifying effect is improved.
Further, the air outlet pipe is positioned below the spray header.
Further, the number of the spray heads is multiple, and the spray heads are arranged in parallel. Thus, the washing liquid can be sprayed into the tower body more uniformly.
Further, the tower body is made of stainless steel.
Further, drain outlets are formed in the bottom of the tower body and the bottom of the balance tank. When the washing tower is idle, liquid in the tower can be discharged, and corrosion of the liquid to the tower body is prevented.
Further, the side wall of the tower body is provided with an access hole, so that the inside of the tower body is convenient to maintain.
The working principle of the utility model is as follows: when the flue gas is washed, the flue gas enters the tower body from the air inlet pipe, the washing liquid enters the tower body from the liquid inlet pipe, the washing liquid is dispersed by the spray header, and the gas-liquid phase moves in the opposite direction. The falling liquid is settled at the bottom of the tower body, and the balance tank and the tower body form a communicating vessel structure, and the height of the liquid outlet pipe is lower than that of the air inlet pipe, so that the liquid can be discharged in time and cannot enter the air inlet pipe, and the backflow of the liquid is avoided.
The beneficial effects of the utility model are as follows:
according to the utility model, the balance tank and the tower body form a communicating vessel structure, and the height of the liquid outlet pipe is lower than that of the air inlet pipe, so that the backflow of the washing liquid is avoided. Compared with the existing equipment, the utility model reduces the liquid level gauge and the liquid pump and reduces the cost of the equipment.
