Residual temperature heat exchange demisting spray tower

Abstract: The utility model discloses a residual temperature heat exchange demisting spray tower, which comprises an air blower, a water pump, a tower body, a water storage chamber formed at the bottom of the tower body, a tower body drain pipe arranged at the bottom of the water storage chamber, an air outlet formed in the top end of the tower body, a demisting layer, a first spray layer, a second spray layer, an air inlet pipeline arranged on one side of the upper part of the tower body, and a water inlet pipe arranged outside the tower body, wherein the demisting layer, the first spray layer and the second spray layer are formed in sequence between the inner air outlet and the air inlet of the tower body; the first spray layer and the second spray layer are connected with the water inlet pipe through spray pipes. By adopting the residual temperature heat exchange demisting spray tower, tar and dust in waste gas can be removed effectively, and heat exchange can be performed in order to save resources and maximize the energy utilization ratio.

Centrifugal spray tower

Abstract: The invention discloses a centrifugal spray tower. The centrifugal spray tower comprises a shell, wherein a lower cavity is formed in the lower part of the shell; a flue gas inlet for flue gas to enter is formed at the lower cavity of the shell; the top of the shell is provided with a flue gas outlet for desulfurized flue gas to be discharged; the bottom of the shell is provided with a liquid outlet for discharging a reacted absorbent; spraying layers for spraying the absorbent to an inner cavity of the shell are arranged in the inner cavity of the shell; a rotating mechanism which is used for enabling the flue gas in the whole inner cavity of the shell to move at a high speed under the action of centrifugal force according to a spiral or rotational flowing track to increase the contact frequency and the contact strength of the flue gas and the absorbent is arranged at least one of the followings: at the upper part of the spraying layers, between the adjacent spraying layers and at the bottom of the spraying layers. According to the centrifugal spray tower disclosed by the invention, the size of the spray tower can be reduced, and the investment, the operation cost and the operation power can also be reduced; meanwhile, the effects of fast desulfurization, dust removal and the like can be achieved.

Experimental evaluation of the removal efficiency of so2 in a spray tower using different spray nozzles

Abstract: This work presents an experimental evaluation of the removal efficiency of SO2 in a spray tower. The experiments were carried out in different conditions, varying gas velocity and using different sprays nozzles. The influence of the height of tower on the removal efficiency was evaluated through experiments inside spray tower. In this study was used two sets of five nozzles, with diameter of orifice of 2.4 and 3.2 mm, and only one nozzle with diameter of orifice of 5.6 mm. The results showed the influence of the gas velocity and L/G ratio in the removal efficiency, the influence of the gas velocity on the volumetric gas side mass transfer coefficient and the influence of the height of the tower in the removal efficiency.

Process for making alkali metal polyphosphates

Abstract: The disclosure relates to a process for making alkali metal polyphosphates, especially alkali metal triphosphates. To this end, the disclosure provides for an alkali metal phosphate solution or suspension to be forced through at least one nozzle and for them to be sprayed inside a spray tower through a flame zone produced by a one or more burners arranged in annular fashion. More particularly, the disclosure provides for fine particulate alkali metal polyphosphates, especially alkali metal triphosphates, to be additionally introduced into the spray tower from above and for them to be regularly distributed across the spray region(s) of the nozzle(s) with formation of agglomerated products. The disclosure also relates to an apparatus for carrying out the process. The apparatus is comprised of a cylindrical spray tower (1) having a tapered lower end (3) and being closed by means of a cover (2); a spray means (6) being passed centrally through the cover (2); a plurality of burners (11) and a solid matter feed means being passed through the cover concentrically with respect to the spray means (6) and so as to be spaced therefrom; and a bevelled issuing gas outlet (4) opening upwardly from the tapered end of the spray tower (1).

Biomass energy gasification centralized air-supply tobacco leaf baking device

Abstract: The utility model relates to a tobacco baking device with gasification and centralized gas supply of biomass energy. A stalk gasifying furnace, a gas storage tank, heat exchangers and combustors are combined together and innovated, a fuel gas outlet on the side of the stalk gasifying furnace is connected in series with two stages of spray towers in sequence through pipelines, the rear-stage spray tower provided with a filter screen is connected with a cyclone dust collector through a gas outlet at the upper end of the rear-stage spray tower, the gas outlet at the upper end of the cyclone dust collector is connected with a filter through a vacuum pump, the filter provided with a filter screen is connected with the gas storage tank through a gas-water separating flame arrestor, the gas outlet of the gas storage tank is connected with a gas line network through a flame arrestor, the gas line network is connected with the combustors arranged in each tobacco baking house, and the gas outlet pipes of the combustors are communicated with the gas inlet connector of the heat exchangers installed in the tobacco baking houses; the tobacco baking device has the advantages that the maintenance and the operation are simple, the required operating personnel are few, the entire system only needs two to three persons, and the labor intensity of the operating personnel can also be reduced.
