Abstract
The utility model discloses a sodium nitrate solution tail gas absorber, the control unit comprises a reaction vessel, the last tail gas absorbing device that is connected with of reation kettle, tail gas absorbing device includes the absorption tower, the absorption tower bottom is provided with air inlet and waste liquid export, and the absorption tower top is provided with the shower head and tail gas exports, waste liquid export bottom is provided with the waste liquor recovery groove, be provided with the pipe in the tail gas export and be connected with the waste liquor recovery groove. The utility model discloses technical scheme's a sodium nitrate solution tail gas absorber, simple structure, the absorption of tail gas in the realization sodium nitrate solution production that can furthest to the recovery and the utilization of furthest's realization tail gas, through three steps of absorption and recovery to tail gas, the absorption rate of tail gas reaches 98.5% in the realization sodium nitrate solution, has avoided getting rid of of acid tail gas, has realized the protection of environment and saving of cost.
Description
Technical field
The utility model belongs to the utility model sodium nitrate solution tail gas absorber that the tail gas produced when producing sodium nitrate solution in chemical industry carries out efficient absorption.
Background technology
Current, in chemical industry sodium nitrate solution production process, the method of its tail gas absorption is a lot, but truly all absorption is all be difficult to accomplish, this all can produce a very large impact production, life, safety, environmental protection etc., for solving the tail gas absorption in sodium nitrate solution production process, become a large headache of sodium nitrate solution production industry.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, absorbs sodium nitrate solution tail gas absorber completely.
A kind of sodium nitrate solution tail gas absorber of technical solutions of the utility model, comprise reactor, described reactor is connected with device for absorbing tail gas, described device for absorbing tail gas comprises absorption tower, air inlet and waste liquid outlet is provided with bottom described absorption tower, top, absorption tower is provided with spray head and offgas outlet, is provided with devil liquor recovery groove bottom described waste liquid outlet, described offgas outlet is provided with conduit and is connected with devil liquor recovery groove.
Preferably, be provided with column plate in described absorption tower, described column plate is provided with filler, described filler is cylindrical tube, and described filler material is PVC.
Preferably, described reactor is sodium nitrate solution preparation feedback still, described reactor top is provided with exhaust outlet one, described exhaust outlet one is provided with stainless steel tube, described stainless steel tube is connected with the air inlet bottom absorption tower, and exhaust outlet one position at described reactor top is lower than the air inlet position bottom absorption tower.
A kind of sodium nitrate solution tail gas absorber of technical solutions of the utility model, the tail gas main component of sodium nitrate solution is NO, NO2, NaNO2, NaNO3 etc., the stainless steel tube between coupled reaction still and absorption tower is utilized to carry out the first step condensation of tail gas, due to what stainless steel tube was upwards arranged, secondary response and utilization is carried out again when just there will be after condensation appears in tail gas to flow backward in reactor, and enter in absorption tower without the air inlet of tail gas through absorption tower of condensation, sodium hydroxide solution is atomized and makes it to carry out chemical reaction with tail gas by the spray head at top, absorption tower, generate the pollution-free material such as salt and water, and be expelled to devil liquor recovery groove in by the waste liquid outlet on absorption tower by spraying out unnecessary sodium hydroxide solution together with the material of generation, by through absorption tower, the offgas outlet of incomplete systemic a small amount of tail gas through absorption tower is expelled to bottom the solution in devil liquor recovery groove, realize absorbing the third time of tail gas, guarantee the absorption completely of tail gas, avoid the pollution of environment.
The utility model technology beneficial effect:
A kind of sodium nitrate solution tail gas absorber of technical solutions of the utility model; structure is simple; the absorption of tail gas in sodium nitrate solution production can be realized to greatest extent; and realize the Collection and utilization of tail gas to greatest extent; through three steps to the absorption of tail gas and recovery; realize the absorptivity of tail gas in sodium nitrate solution and reach 98.5%, avoid the eliminating of acid tail gas, achieve the protection of environment and the saving of cost.
