Polycrystalline silicon tail gas spray tower

Abstract: The utility model discloses a polycrystalline silicon tail gas spray tower, comprising a tower body, wherein an air inlet, an air outlet and a liquid outlet are arranged on the tower body, a spray pipe penetrates through the tower body and is arranged at the middle-upper part of a spray cavity, and the tail end of the spray pipe is further provided with a blade type turbulent flow generator. Spray liquid forms into turbulent flow through the spray pipe to the blade type turbulent flow generator, so that the spray liquid is even in spraying (the generated turbulent flow is fully mixed with waste gas in the air inlet), and the time for water contacting with gas such as trichlorosilane and the like is prolonged, therefore, the gas such as the trichlorosilane and the like can be more fully hydrolyzed ,the work efficiency can be greatly improved, the occurrence of a pipe plugging condition can be overcome, and the occurrence of dangerous accidents such as pipe explosion and the like can be reduced.

Waste gas spray tower for melting furnace

Abstract: The utility model discloses a waste gas spray tower for a melting furnace. An air inlet is positioned on the lower part of the waste gas spray tower; an air outlet is positioned at the top end of the waste gas spray tower; a space in the spray tower can be partitioned by at least two filtering layers which can move up and down and add a dismounting function; each of the filtering layers comprises a support frame and filtering screen plates supported by the support frame; screen holes of which the aperture is 10-50mm and which are uniformly distributed are formed on the filtering screen plates; by the filtering screen plates, orthographic projection generated by vertical parallel light is used as a reference, shadow images of the screen holes are not mutually superposed in the orthographic projection of adjacent filtering screen plates; spray frames are arranged above each of filtering layers; and a plurality of nozzles which can be selectively mounted are arranged on a frame body. The waste gas spray tower for the melting furnace has the advantages that the waste gas spray tower is adapted to different types of waste gases to filter and remove dust, the effect of fully spraying can be achieved, and the spraying quality is improved to the maximum limit.

Novel spray equipment

Abstract: The invention discloses novel spray equipment and relates to the technical field of spray A filler layer is arranged in a spray tower, a filler outlet is mounted on one side surface of the filler layer, a water tank is mounted on one side surface of the spray tower, an anti-corrosion pimp I is connected with the water tank through a pipeline and connected with a spray port of the spray tower through a pipeline, the water tank is connected with a waste heat concentration device through a pipeline and a solenoid valve I, and a wastewater tank is mounted at the lower end of the waste heat concentration device A control method of the equipment comprises steps as follows: at the stage i, the solenoid valve I is opened, a solenoid valve II is closed and an anti-corrosion pump II is opened in the period a; at the stage ii, the solenoid valve I is closed, the solenoid valve II is opened and the anti-corrosion pump II is closed when the period a is up; a liquid level switch alarms to circulate to the stage i when the liquid level is decreased to L1; a liquid level alarm performs alarm protection when the liquid level is decreased to L2, and the anti-corrosion pump II is closed The equipment facilitates quick and accurate control and is convenient to use and operate, time-saving and high in working efficiency

Desulfurization spray tower

Abstract: The invention relates to a desulfurization spray tower. The desulfurization spray tower comprises a tower top and a tower body, wherein the top of the desulfurization spray tower is provided with a smoke outlet; an access port is reserved on one side at the top of the desulfurization spray tower; a smoke inlet is arranged on one side on the lower part of the desulfurization spray tower; the bottom of the desulfurization spray tower is provided with an overflow port; an anti-flushing device, a demisting device, a spraying device and an air flow distributing device are arranged in the desulfurization spray tower from the top to the bottom in turn; and a granite lining is paved on the inner wall of the desulfurization spray tower. The desulfurization spray tower has a simple structure, increases the spray range of spray equipment, improves the work efficiency of a desulfurization tower, reduces the resistance of desulfurization equipment per se, ensures normal operation of production on the premise of not replacing a boiler fan, saves the cost for replacing the fan and prolongs the service life of the desulfurization equipment.

Polycarboxylate water reducing agent waste gas treatment system

Abstract: The utility model discloses a polycarboxylate water reducing agent waste gas treatment system, include and inhale waste gas from the bottom and carry out the abstergent absorption tower of alkali lye to waste gas, say with absorption tower tube and be connected and carry out the abstergent spray column of secondary alkali lye to the absorption tower combustion gas, with spray tower tube and say the adsorption tank that is connected and carries out the active carbon adsorption processing to the spray column combustion gas, the absorption tower includes the absorption tower main part, vacuum pump to absorption tower main part evacuation, with the alkali lye of absorption tower main part bottom take out the top of the tower unrestrained and with waste gas countercurrent contact's first circulation mechanism, the spray column includes the spray column main part with absorption tower main part pipe connection, with the alkali lye of spray column main part bottom take out the top of the tower unrestrained and with gaseous countercurrent contact's second circulation mechanism. The utility model discloses an absorption tower and spray column be to the waste gas washing of establishing ties, carries out active carbon adsorption through the gas of adsorption tank after to the washing of establishing ties and handle, thoroughly gets rid of the harmful components in the waste gas, gets rid of efficiently, improves operation ambient air quality.
