The utility model eliminates the disadvantages of large gas-stagnation resistance and inverse filling of spraying and condensing oil gas existing in the present waste gas purifying device, and has the advantages of high waste gas purifying speed and high purification degree. The waste gas purifying device is chiefly used for textile dyeing and finishing industries, and is also applied to the condensation and purification of high-temperature waste gas in other industries.
Description
(1) technical field: the utility model belongs to environmental protection equipment, relates in particular to the off-gas cleaning equipment that emphasis is applied to the textile dyeing and finishing industry.
(2) background technology: in the dyeing and finishing industry, the waste gas such as oil smoke that forming machine is discharged must purify just and can be discharged in the atmosphere through purifier.Utilize a spray column to purify in the prior art, waste gas enters in the tower from the mouth of pipe on the tubular body of the tower sidewall, tower internal upper part device sieve tray, the spray head of the top device water of sieve tray, water sprays from top to bottom from spray head, and waste gas flows after entering in the tower from the bottom up, and the oil smoke in the waste gas is discharged at the bottom of the shower water condensation falls into tower, so realize the purification to waste gas, the gas through purifying is from tower top discharge.Also be placed with cobble on sieve tray, waste gas and shower water to increase the condensation contact area, strengthen clean-up effect through sieve aperture and the circulation of cobble slit.
Because waste gas and shower water are through sieve tray and cobble circulation, make waste gas in spray column, be subjected to very big stagnation of the circulation of vital energy resistance, waste gas flow velocity and purification speed are extremely slow, even more serious is often to occur pouring in down a chimney into forming machine through the waste gas of spray and through the steam of condensation, the mouth of pipe of lubricator process body of the tower sidewall, influence the operate as normal and the dyeing and finishing quality of forming machine, pour in down a chimney lubricator even exist in hidden danger on fire in the hot environment of forming machine.
(3) summary of the invention: the applicant designs another kind of emission-control equipment at above-mentioned existing problems, and it can overcome above-mentioned stagnation of the circulation of vital energy resistance and spray the shortcoming that condensation oil smoke gas pours in down a chimney, and waste gas purification speed is fast, the degree of purification height.
The technical solution of the utility model is as follows: it is connected and composed by spray washing device and gas-liquid separation device, be characterised in that: described spray washing device is constructed as follows: connect pipeline section by exhaust input tube section, convergent pipeline section, trunnion section, flaring pipeline section and a left side and be linked in sequence, device water spray head above the trunnion section is as purifying first passage; Described gas-liquid separation device is constructed as follows: connect pipeline section, convergent pipeline section, trunnion section, filtration pipeline section and exhaust pipeline section by the right side that has leakage fluid dram and be linked in sequence, as purifying second channel; Described left side connection pipeline section is connected pipeline section with the right side and is connected.At the exhaust input tube section apparatus water spray head of first passage, perhaps at the reducing pipe section apparatus water spray head of first passage.Install deflector in a left side connects pipeline section, perhaps, it is the curved pipe structure that a left side connects pipeline section.In connecting pipeline section, the right side installs deflector.Can also in second channel, install screen pack, perhaps between described screen pack, install sorbing material, perhaps device water spray head above the screen pack in second channel.
In the utility model, constitute first order Venturi tube by convergent pipeline section, trunnion section and flaring pipeline section in the first passage, constitute the air-flow accelerating sections of second level Venturi tube in the second channel by convergent pipeline section and trunnion section, by of water conservancy diversion and the acceleration of two-stage Venturi tube to off-gas flows, effectively eliminated stagnation of the circulation of vital energy resistance phenomenon, waste gas purification speeds up.A left side connects pipeline section and the right pipeline section that connects is designed to the water conservancy diversion pipeline section, further accelerates waste gas flow velocity and waste gas purification speed.
The utility model in first passage the exhaust input tube section or further the water spray head is installed at its convergent pipeline section, can also the water spray head be installed at the convergent pipeline section of second channel in case of necessity, carry out one-level, secondary or three grades of sprays on demand to waste gas; Screen pack can also be installed in second channel, perhaps can also between two-layer screen pack, install sorbing material.Select above all purification means on demand, make waste gas can reach the high purification degree, again to airborne release.The condensation waste liquid and the washings that discharge in the purification process input to oil water separator by leakage fluid dram, separate the water that obtains and send the reuse of spray head secondary back to through water pump again, so fully using water wisely.
(4) description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of water spray head in the utility model.
(5) specific embodiment:
The utility model is connected and composed by spray equipment and gas-liquid separation device.See Fig. 1, spray equipment is constructed as follows: connect pipeline section 7 orders by exhaust input tube section 1, convergent pipeline section 3, trunnion section 5, flaring pipeline section 6 and a left side and be welded to connect, as the waste gas purification first passage.Outside at pipeline section 3, trunnion section 5 and pipeline section 6 is welded with outer cover.Device water spray head above trunnion section 6, its can be waste gas enters pipeline section 1 in by the holder device spray head, Fig. 1 illustrates three spray heads 2 is installed, its horizontal direction is in triangular distribution, and constitutes one-level and sprays; Also can be further in convergent pipeline section 3 by holder device spray head 4, constitute the secondary spray.Device deflector 8 carries out water conservancy diversion and acceleration to off-gas flows in a left side connects pipeline section 7, perhaps a left side can be connected pipeline section 7 and be made as the curve channelization tube shape, but manufacture difficulty and cost strengthens.
See Fig. 1, gas-liquid separation device is constructed as follows: be welded to connect and constituted by the right side connection pipeline section 12 that has leakage fluid dram 11, convergent pipeline section 18, trunnion section 19 orders, as the waste gas purification second channel.Left side connection pipeline section 7 is connected pipeline section 12 with the right side and is connected, and can as shown in Figure 1ly be tightly connected with flange 10, also can directly weld.
