6, in the utility model, by the cooperation of bleeding between near the 3rd pressure modulating opening 311 the 4th pressure modulating opening 351 on vacuum tank 35 and microwave heating equipment 38, cause the inner negative pressure that forms of microwave heating equipment 38, and then generation one air-flow, the top air inlet of this air-flow lower tank 31, and through vacuum tank 35, take away the water vapour that microwave heating process produces, steam can be delivered in vacuum tank 35 by tube connector, and be condensed into aqueous water at vacuum tank 35, and be delivered in sewage plash 37 by second row water pipe, so can ensure that the moisture in lower tank 31 is disposed in sewage plash 37 comparatively fully.
7, in the utility model, by metallic shield ring 381 and metallic shield net 382 are set, can make the microwave can repeated reflection in microwave heating equipment 38, avoid the microwave producing in dry run to leak. Also can make mud be dried by homogeneous heating, further improve the drying effect of mud simultaneously.
8, in the utility model, by the first pressure sensor module 17 and the first relief valve 18 are set, and coordinate the ventilation effect of Blast mechanism 4, can form a pressures cycle treatment system, after the first tank body 10 internal cause ventilations cause air pressure to increase, can increase the infiltration to mud internal void of Interstitial Water and thiobacillus thiooxidant, the contact frequency of oxidation reinforced Thiobacillus and mud, improve the ability of heavy metal in its picked-up mud, when the first tank body 10 internal pressures increase to after 700kPa, the first pressure sensor module 17 detects after this pressure peak threshold value, touching Blast mechanism 4 stops to the interior ventilation of the first tank body 10, and start the first relief valve 18 simultaneously, above-mentioned the first relief valve 18 is controlled the first tank body 10 exhausts, the pressure of the first tank body 10 inside is reduced to atmospheric pressure by 700kPa, the microbubble that the top of described the first tank body 10 is a large amount of because exhaust produces, gas in Interstitial Water can disengage and take heavy metal and reacted product out of mud hole. because the hole of mud is too small, the speed that when decompression, gas disengages is often greater than the speed that gas is discharged from hole, therefore causes mud hole internal pressure to increase. in the time that mud hole internal pressure is greater than the pressure that mud granule wall can bear, just can cause mud granule implode or burst, the exposed amount of heavy metal in mud is increased, greatly improve the gas-solid contact effect of heavy metal and thiobacillus thiooxidant, strengthen its biochemical reaction, greatly improve the removal effect of Heavy Metals in Sludge, in the time that the pressure in the first tank body 10 returns to general atmosphere pressure, the first pressure sensor module 17 detects after this pressure minimum point threshold value, touch Blast mechanism 4 again to the interior ventilation of the first tank body 10, and close the first relief valve 18 simultaneously, after again the first tank body 10 internal pressures being risen to 700kPa, be again depressurized to atmospheric pressure, constantly complete the circulation of supercharging and decompression, until mud completes the removal of heavy metal.
9, in the utility model, by the second pressure sensor module 27 and the second relief valve 28 are set, and coordinate the ventilation effect of Blast mechanism 4, can form another pressures cycle treatment system, after the second tank body 20 internal cause ventilations cause air pressure to increase, can increase the infiltration of Interstitial Water and three kinds conditioning material to mud internal void, strengthen the contact frequency of three kinds of conditioning material and mud, improve the effect of its opsonic reaction, when the second tank body 20 internal pressures increase to after 700kPa, the second pressure sensor module 27 detects after this pressure peak threshold value, touching Blast mechanism 4 stops to the interior ventilation of the second tank body 20, and start the second relief valve 28 simultaneously, above-mentioned the second relief valve 28 is controlled the second tank body 20 exhausts, the pressure of the second tank body 20 inside is reduced to atmospheric pressure by 700kPa, the microbubble that the top of described the second tank body 20 is a large amount of because exhaust produces, gas in Interstitial Water can disengage and take the product after opsonic reaction out of mud hole. because the hole of mud is too small, the speed that when decompression, gas disengages is often greater than the speed that gas is discharged from hole, therefore causes mud hole internal pressure to increase. in the time that mud hole internal pressure is greater than the pressure that mud granule wall can bear, just can cause mud granule implode or burst, make polyelectrolyte and the increase of organic exposed amount in mud, greatly improve the gas-solid contact effects of itself and three kinds conditioning material, strengthen its physical and chemical reaction, thereby can reduce yield stress and the outward appearance viscosity of mud, contribute to improve sludge dewatering effect, in the time that the pressure in the first tank body 10 returns to general atmosphere pressure, the first pressure sensor module 17 detects after this pressure minimum point threshold value, touch Blast mechanism 4 again to the interior ventilation of the first tank body 10, and close the first relief valve 18 simultaneously, after again the first tank body 10 internal pressures being risen to 700kPa, be again depressurized to atmospheric pressure, constantly complete the circulation of supercharging and decompression, until mud completes overall dehydrating and conditioning.
Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
