Accompanying drawing explanation

Accompanying drawing 1 is the structural representation of the comprehensive wet dust separater of scavenging vehicle.

The specific embodiment

Contrast accompanying drawing 1, the comprehensive wet dust separater of scavenging vehicle, its structure comprises water tank, inlet plenum 1, S shape passage 2, air-purifying chamber 3, baffle plate 4, feed pipe 5, mud valve 6, the spill box 7 that adds surfactant, the gentle dirty agent of bacteriostatic agent; Wherein the top of water tank is inlet plenum 1, there is air inlet in left side at inlet plenum 1, in water tank, there is S shape passage 2, S shape passage 2 communicates with air-purifying chamber 3, air-purifying chamber 3 device top board belows are baffle plates 4, spill box 7 is equipped with in the right outside of air-purifying chamber 3, the left-external side dress feed pipe 5 of water tank, the bottom dress mud valve 6 of device.

In described water tank, adding surfactant is polyacrylamide PAM compound, and this PAM compound comprises that mass concentration is 0.05～0.4% polyacrylamide PAM, the dioctyl sodium sulfosuccinate AOT that mass concentration is 0.05～0.4%, the Na that mass concentration is 0.5～5mmol/L ₂sO ₄with mass concentration be 1% NaOH or hydrochloric acid solution, its pH value to 6～10.

The slow dirty agent and the bacteriostatic agent that in described water tank, add are polyquaterniums, consumption 20～50 m g/L.

1) wet scrubber is provided with S shape passage; S shape passage consists of upper and lower blade, when the serpentine passage forming by upper and lower blade with 8～35m/s when dusty gas flows into clean room, can evoke a large amount of sprays, water, gas are fully contacted, dusty gas is purified, and dust removal efficiency can reach more than 99%, reduces water level fluctuation simultaneously.

2) in water tank, add polyacrylamide PAM compound as surfactant; Dust is more easily caught by water, and make more free settling of dust, the Na that the dioctyl sodium sulfosuccinate AOT that the polyacrylamide PAM that this PAM compound is 0.05～0.4% by mass concentration, mass concentration are 0.05～0.4%, mass concentration are 0.5～5mmol/L ₂sO ₄with mass concentration be 1% NaOH or the composite adjusting pH of hydrochloric acid solution value to 6～10.

3) in water tank, add polyquaternium as slow dirty agent and bacteriostatic agent; Use amount is controlled at 20-50 m g/L.

Embodiment 1

(1) the serpentine passage that dusty gas forms by upper and lower blade with 15m/s flows into clean room, can evoke a large amount of sprays, and water, gas are fully contacted.

(2) in water tank, add surfactant PAM compound, regulate the concentration of each material to be respectively: AOT concentration 0.15%, PAM concentration 0.02%, Na ₂sO ₄concentration 2mol/L also regulates pH value to 7 can reach optimum wettability effect, and efficiency of dust collection can reach more than 97%.

(3) in water tank, adding polyquaternium is 30mg/L as slow dirty agent and bacteriostatic agent concentration, and bacteriostasis rate reaches more than 99%, and slow dirty rate can reach 98.5%.

(4), by the Comprehensive Control of above each side, the efficiency of dust collection of this scavenging vehicle wet type combined dust-eliminating system can reach 99%.

In the water tank of deduster, add surfactant, reduce water surface tension, improve the wetability of dust, thereby improve the arresting efficiency to hydrophobic dust.Also add the gentle dirty agent of certain bacteriostatic agent, be conducive to circulation and the recycling of water, realized the real performance of sweeper dedusting.Simple in structure, cost is low, and operational effect is good, can remove pernicious gas simultaneously, has effectively realized the cycling and reutilization of high-effective dust-removing and water.

During work, dusty gas enters inlet plenum 1 by entrance, and the larger grit of part is because effect of inertia falls within water; When dusty gas passes through the S shape passage 2 of upper and lower blade with the speed of 8 ~ 35m/s, evoke a large amount of sprays, make water, gas contact, the grit of most particulates is sneaked in water, and dusty gas is purified; After serpentine passage 2, due to the effect of centrifugal force, the water that obtains grit returns again in water tank; Purified gas You Fen fog chamber baffle plate 4 is removed water droplet and is discharged by air-purifying chamber 3 outlets, and mud pulp-expelling valve 6 is discharged termly.New water has feed pipe 5 tunnels to supplement; Water level in unit is controlled by spill box 7; Water in water tank has added certain medicament, add polyacrylamide (PAM) compound solution as surfactant, polyquaternium is as the gentle dirty agent of bacteriostatic agent, all reagent adds in water tank as the cleaning solution of deduster, can improve deduster to the efficiency of dust collection of fine dust and reduce the performance of the flowing resistance aspect of deduster.

The above, is just to simple declaration of the present invention, rather than limitation of the present invention, any innovation and creation that do not exceed essence of the present invention, all fall within the scope of protection of the present invention.
