Abstract
The utility model discloses a water-seal type ventilator capable of inspiration and expiration, which relates to a tail-gas disposal and purification device that can be used in the coking industry to dispose and purify the tail gas generated from a chemical products recover plant, a pool and a tar ship, etc. By employing the water seal principle, the water-seal type ventilator capable of inspiration and expiration can prevent the contact of the inside and outside air bi-directionally, thereby avoiding disorderly emission of the harmful gas. The water-seal type ventilator capable of inspiration and expiration comprises a water tank, a clapboard is arranged above inside of the water tank, the top part of the water tank is connected with an air-exhaust pipe and a water-intake pipe, the side wall of the water tank is connected with an air-intake pipe, an overflow hole is arranged on the place at the lower part of the air-intake pipe, corresponding to the side wall of the water tank, the bottom of the water tank is provided with a clean water hole. The water-seal type ventilator capable of inspiration and expiration can prevent the contact of the inside and outside air bi-directionally and prevent the harmful gas from disorderly emitting. The water-seal type ventilator capable of inspiration and expiration has the advantages of fire prevention, low investment, low operation coat and small floor area, and is suitable for diversified materials.
Description
Technical field
This practical processing and purifier that relates to device exhausts such as groove, pond, tar ship between coking industry chemical products recovery vehicle is specifically related to a kind of hydrolock respirator of can be air-breathing, exhaling.
Background technology
Comprise a lot of grooves pond between the coking industry recovery vehicle, material also is varied in the groove pond, as: tar, high concentration ammoniacal liquor, cyanide wastewater, crude benzol, washing oil, crude phenols, acid, alkali etc.
At coking industry groove pond exhaust emission situation, domesticly mainly contain three kinds of solutions: the one, establish breather valve at top, groove pond, the 2nd, establish the washing, purifying tower, the 3rd, exhaust stack is installed at the top.Breather valve is similar to unidirectional check (non-return) valve, and it can only outwards be exhaled, can not be inwardly air-breathing, and when system's internal pressure raise, gas just passed through the outside emptying of breather valve, guaranteed the constant pressure of system, and generally it is used on normal pressure or the low-pressure tank.The washing, purifying tower is the exhaust-gas treatment special equipment, and main effect is that waste gas is introduced in the tower, adopts particular fluid to spray washing.When exhaust stack was installed at the top, the waste gas that the material volatilization produces constantly entered atmosphere, makes plant area's air pollution serious, is filling the air the smell of various harmful substances, and worker healthy caused very big threat.
At coking industry groove pond exhaust emission situation, be necessary to research and develop a kind of new device, to solve the defective that prior art exists.
Summary of the invention
The purpose of this utility model provides a kind of hydrolock respirator of can be air-breathing, exhaling, and utilizes water-seal principle, reaches the gas contact of two-way prevention inside and outside, prevents the unordered purpose of diffusing of pernicious gas.
The utility model is achieved through the following technical solutions:
A kind of hydrolock respirator of can be air-breathing, exhaling, comprise water tank, the top of water tank inside is provided with dividing plate, tank top is connected with blast pipe and water inlet pipe, be connected with air inlet pipe on the water tank sidewall, the relative position of the water tank sidewall of air inlet pipe bottom offers overfall, and water tank bottom offers the water purification mouth.During use, be installed on the exhaust stack of former groove pond, utilize the water surface of certain altitude in the device to play the water seal effect, make the inner pressure stable that keeps in groove pond, and waste gas is washed purification in device when overflowing, reduced discharge of harmful gases, the water purification mouth that water tank bottom is offered can be discharged recirculated water, thoroughly cleans water tank bottom.
Described air inlet pipe is provided with air intake valve.
Compared with prior art, the utlity model has following advantage:
(1) utilize hydrolock respirator principle, two-way prevention inside and outside gas contact prevents from that pernicious gas is unordered to diffuse;
(2) utilize the pressure reduction of dividing plate and overflow pipe to make water tank inside remain certain liquid level, and can rely on inlet valve to regulate the size of inflow;
(3) have the function of back-fire relief, prevent from that outside naked light from contacting with the burnable gas of inside, groove pond to set off an explosion.
(4) compare with breather valve, the utlity model has purification function, can not only exhale, also can be air-breathing, groove pond pressure stability; Compare with the washing, purifying tower, the utility model cost of investment, operating cost are low, and floor space is less, and the material variety that is suitable for is many.
