Circulating spray type steel slag hot soaking steam treatment device

Abstract: The utility model discloses a circulating spray type steel slag hot soaking steam treatment device comprising a slag soaking pit for stacking steel slag, wherein the top of the slag soaking pit is sealed and covered by a slag soaking cover; an air outlet is formed in the side wall of the slag soaking cover; the slag soaking pit is communicated with a spray tower through a steam pipeline communicated with the air outlet formed in the side wall of the slag soaking cover; a plurality of straight pipes are distributed in the spray tower along the circumferential direction; a plurality of annular pipes communicated with the straight pipes are arranged from top to bottom inside the spray tower at intervals; a plurality of spray pipes provided with nozzles are distributed on each annular pipe along the circumferential direction; the steam pipeline extends from the top of the spray tower to the inside of the spray tower; the steam pipeline extending into the spray tower is annularly sleeved by the annular pipes; a water outlet is formed in the lower side wall of the spray tower; the spray tower is communicated with an inlet of a cooling tower through a first water return pipeline; the cooling tower is communicated with a pool through a second water return pipeline; and the pool is used for supplying water to the straight pipes through water supply pipelines. The circulating spray type steel slag hot soaking steam treatment device has the advantage that steam generated after steel slag is hot-soaked can be effectively treated.

Hybrid synergetic enhanced low-temperature plasma air purifying equipment

Abstract: The invention discloses hybrid synergetic enhanced low-temperature plasma air purifying equipment, which comprises a rotary spray tower, an oil absorption and dust collection mesh, a rare earth catalysis mesh, a siphon anion mesh, a UV (Ultraviolet) light generator, a multi-unit plasma module, an ozonolysis mesh, an induced draft fan and a shell. The oil absorption and dust collection mesh, the rare earth catalysis mesh, the siphon anion mesh, the UV light generator, the multi-unit plasma module and the ozonolysis mesh are sequentially arranged in a shell from a polluted air purification upstream to a polluted air purification downstream; an outlet of the rotary spray tower is communicated with an inlet of the shell; an outlet of the shell is communicated with an inlet of the induced draft fan. According to the hybrid synergetic enhanced low-temperature plasma air purifying equipment provided by the invention, on the basis of de-dusting, de-oiling and purifying particles, the rotary spray tower and the siphon anion mesh are additionally arranged, so that the air is more moistened and higher in oxygen content, negative oxygen ions, ozone, hydroxyl ions and hydrogen ions are greatly increased, the decontamination efficiency is improved, the plasma module is cleaned, and the equipment can operate more smoothly.

Desulfurizing spray tower

Abstract: The utility model provides a desulfurizing spray tower, including the tower body, the top top of tower body is equipped with the gas outlet the inside top of tower body is equipped with the defogging layer, is equipped with multiple layer distribution's filter layer below the defogging layer the below of filter layer is equipped with the reaction tank, and open the tower body side between the filter layer of reaction tank upper portion and lower floor has the air inlet, the reaction tank is connected with main water pipe through the circulating pump, the main water pipe other end is connected with first shower and second shower, first shower and the vertical setting of second shower edge tower body inner wall first shower and second shower equipartition have a plurality of shower nozzles The beneficial effects of the utility model are that the quick equipartition of flue gas flow state in the desulfurizing tower can be makeed, exhanst gas outlet sulfur dioxide problem not up to standard is avoided

Purification of waste gas of nox absorption tower

Abstract: PURPOSE:To prevent a danger of explosion due to accumulation of ammonium nitrate, etc by washing a waste gas in a spray tower to reduce amounts of ammonium nitrate and ammonium nitrite to below a given amount, elevating the pressure, heating, adding NH3 and decomposing NOx in a reactor filled with a catalyst CONSTITUTION:Waste gas containing NOx and small amount of ammonium nitrate and nitrite, is washed in a spray tower under a spray pressure of 2 to 20 kg/cm , in a total spray amount of 2 to 20 l per Nm of the waste gas and at a temperature of below 30 degC, to reduce the total amount of ammonium nitrate and nitrite present in the waste gas to below 20 ppm After elevating the pressure, heating and adding NH3 to the gas, the resulting gas is introduced into a reactor 5 filled with a catalyst NOx is decomposed by a catalytic decomposition reaction to remove it A preferred gas pressure of the waste gas to be introduced into the reactor 5 is from 300 to 800 mAq, and the preferred temperature is from 250 to 400 degC The operation can be conducted continuously for a long time without the accumulation of ammonium nitrate and nitrite in any steps The waste gas can be purified without the danger of explosion

Converter smoke purifying saturation spray tower

Abstract: The utility model discloses a converter smoke purifying saturation spray tower, including a smoke inlet section, an expansion section (3) and a contraction section (7); wherein the inlet section is composed of a heat insulation water jacket (1) and an overflow water tank (2). The utility model is characterized in that the expansion section (3) is arranged on the lower part of the inlet section; upper, middle and lower cylindrical shells (4, 5, 6) are arranged on the lower end of the expansion section (3); the contraction section (7) is positioned on the lower end of a lower cylindrical shell (6); the inlet section and the expansion section (3), the expansion section (3) and the upper cylindrical shell (4), cylindrical shells and the lower cylindrical shell (6) and the contraction section (7) are firmly connected; a draining hole (8) is arranged on the lower end of the contraction section (7); a smoke outlet pipe (9) is arranged on the side surface of the middle cylindrical shell (5); and at least four layers of spray nozzles are arranged in the saturation spray tower. The saturation spray tower has advantages of simple structure, large circulation area, small resistance, low quantity of turbid circulating water and high purification efficiency.
