Description

Papermaking wastewater is without emission treatment machine

Technical field:

This utility model is by sewage produced by paper-making industry, after high-temperature heating evaporates, is brewed into lignosulfonates ointment, reclaims after the moisture content evaporated processes simultaneously, can the papermaking wastewater that uses of secondary without emission treatment machine.

Background technology:

So far, utilize the multiple methods such as chemistry, medicine, biology to process papermaking wastewater, be all difficult to reach the discharge standard of country, waste industrial resources and water resource；Equipment manufacturing cost and chemistry, medicine, bioequivalence lattice are all expensive, and producer is difficult to accept.

Summary of the invention:

Learn that it is condensed into ointment shape through boiling, and can be used in the commercial production being correlated with containing lignosulfonates in papermaking wastewater according to chemical examination, the moisture content receipts cage of evaporation can be returned simultaneously and can use by secondary after taking process.So, the purpose of this utility model is that papermaking wastewater can be made industrial goods lignosulfonates ointment by design one, can reclaim again the papermaking wastewater doing secondary use after evaporation moisture content processes without emission treatment machine.

Solution of the present utility model is: make a circular distillation water pot, making a conical distillation water tank lid again, cover inwall is that beveled top end installs a gas cleaner, interior filling filtering medium, with the harmful substance in filtering steam, cover and the tight closing lid of tank body；Tank body lower end outlet is connected with water purifier through distillation water pipe, distillation water solenoid valve, distillation water pump, and the water outlet of water purifier is controlled by electrodeionization water purification magnet valve；The open and close of water pump therein and electromagnetic valve are by liquid level self-controller control.Make a circular evaporator less than distillation water pot, its top is by several pillars, support a cone bucker, bucker outer wall is inclined-plane, in case the distillation globule drops in evaporator, it has therebetween corresponding spacing, and boil-off gas can be made unblocked, and evaporator is arranged on the middle part of distillation water pot；Evaporator upper end wastewater inlet is connected with detention tank through soil pipe concatenation, sewage table, sewage electromagnetic valve, sewage pump；Sewage pump and sewage electromagnetic valve are controlled by oil liquid level automatic controller, lower end product outlet, are connected with finished product cooling bay through production tube, finished product valve.Make a circular heat converter less than evaporator, flowline and oil return pipe bracket-suspending are placed in evaporator.Doing a bottom surface and divide the thermal source fuel tank of height two-layer, its lower end oil-out is connected with heat converter lower port through flowline, fuel tap, oil pump；Upper port is connected with heat converter upper port through oil return pipe；Form it into a circulation canal；Formed, by magnetic board and gas furnace, the thermal source that an electricity, gas are dual-purpose, in case having a power failure or dying, it is possible to share simultaneously, accelerate thermal energy to strengthen；Magnetic board heating-surface and the close contact of thermal source fuel tank low bottom surface, gas furnace and thermal source fuel tank height bottom surface are from corresponding spacing, in order to the burning of gas；There are ignition switch and air inlet pipe and the gas solenoid valve controlled by liquid level self-controller in gas furnace side；After the main switch of opening power, the electrical equipment respectively needing action can under the control of liquid level self-controller, automatic action, as magnetic board generates heat, conducting heat and thermal source fuel tank, oil starts heating, open fuel tap, oil is under the driving of oil pump, and oil can carry out quickly constantly circulating in circulation canal, and heat energy is transferred to heat converter, conduction and sewage, sewage heats up and evaporates, and the gas of evaporation forms distillation water, and distillation Water Sproading processes secondary through water purifier and uses.

So, papermaking wastewater, under the decocting of high temperature, forms ointment shape lignosulfonates, for, in relevant commercial production, reusing, accomplish the effect of sewage zero-discharge, be killing three birds with one stone after being recycled by the moisture content of evaporation again simultaneously.
