Abstract
An air curtain type exhaust gas collecting device pertains to the exhaust gas purifying field, which comprises a stove, an air introducing pipe, a blast pipe, a connection pipe, an air curtain forming equipment and a gas skirt. The middle part of the air introducing pipe communicates with the connection pipe which is rested on the top of the gas skirt; the air curtain forming equipment is positioned on the blast pipe, the portion of the blast pipe where the air curtain forming equipment is mounted is opposite to edges of the gas skirt so that the air curtain generated by the air curtain forming equipment and the gas skirt joints to constitute a close system in which the stove is positioned. The device solves the problem of collecting the gas exhausted by a non-close stove; the operator and the material can freely move in the air curtain, requirements for loading and unloading space of the equipment can be met. The device, which is convenient to run and maintain and has little possibility of corrosiveness, can collect much more exhaust gas than only with the gas skirt due to the screening function of the air curtain, up to above 95% of exhaust gas being collected. The device has a simple structure, requires low labor cost and meets environment protection requirements.
Description
Technical field
The utility model relates to the isolated gas sampling device of a kind of air curtain, belongs to the waste gas purification field.
Background technology
As everyone knows, the collection of kiln waste gas is the key technology of kiln waste gas pollution control and treatment, at present mostly adopt the fixed form of divider wall (plate, frame) to carry out to the collection of kiln waste gas, for charging discharging and the frequent kiln of maintenance of equipment, then can't adopt this method to carry out, then occurred collecting with windproof door curtain or the form that adds removable cover, but operate very inconvenient, and equipment corrodes easily, often perform practically no function after service time is long, cause waste gas to add that yield is significantly low to be reduced or can not collect fully, environment is polluted (harm).
Also there is not effectively to collect the device of waste gas in the prior art.
Disclose a kind of electronic kiln waste gas burner in the Chinese patent 200420025449, belonged to environmental protection and energy-conservation facility.It comprises: furnace body frame; Be fixedly arranged on the body of heater on the furnace body frame, body of heater central authorities are formed with burner hearth; Burner is fixedly arranged on one of body of heater end, and its burner passed through body of heater and extend into burner hearth; Some groups of heat exchanger tubes assemble the heat exchange nest of tubes, are located in the burner hearth, and a pair of pipe end of every group of heat exchanger tube communicates with the heat exchanger chamber respectively; Waste gas intake and high temperature air outlet are fixedly arranged on the body of heater respectively, and communicate with furnace chamber and heat exchanger chamber respectively; The cold wind intake is fixedly arranged on the body of heater, communicates with the heat exchanger chamber; Induced duct, the one end communicates with burner hearth, the valve that continued in the middle part of it, its other end is routed on the air-introduced machine.The utility model has the advantages that: embody environmental protection and energy-conservation, be easy to understand and grasp combustion position, convenient for cleaning.This equipment has certain treatment effect to combustible waste gases, still, can't handle for the waste gas of incombustibility.
The device of a kind of environment-friendly type pump drainage oil smoke and waste gas is disclosed in the Chinese patent 02114395, this device is mainly by oil smoke and waste gas suction inlet, blower fan, purifying box, and the connecting pipe between each parts is formed, device passes through the pump drainage wind system with the kitchen, boiler, the oil smoke and the waste gas of kiln or internal combustion engine and the discharging of other place are sent into purifying box, make wherein contained mist of oil, particles such as dust are adsorbed in purifying box with other harmful substance or dissolve, oil smoke and waste gas are discharged in the air after handling through purifying box again, thereby reduce to the pollution of air and building construction and to the destruction of ecological environment.The pump drainage wind system can be collected waste gas effectively, but operation is very inconvenient.
The utility model content
Existing apparatus waste gas yield is low in order to overcome, the deficiency of inconvenient operation, and the purpose of this utility model is: the isolated gas sampling device of air curtain that a kind of waste gas yield height, flexible and convenient operation are provided.
The technical scheme that its technical problem that solves the utility model adopts is as follows: the isolated gas sampling device of air curtain comprises that induced duct, ajutage, communicating pipe also comprise air curtain former, gas skirt; The middle part of induced duct communicated with communicating pipe, be installed in the gas skirt top communicating pipe, install the air curtain former on the ajutage, it is relative with the gas skirt edge that ajutage is installed the part of air curtain former, the air curtain wall that the air curtain former the forms formation closed system that is connected with gas skirt.
Kiln is installed in this closed system, or the kiln ventilating opening is installed in this closed system, or kiln comprises that the part of ventilating opening is located in this closed system.
The isolated gas sampling device of air curtain also comprises fixed frame or fixedly wall or fixed head.
The air curtain wall that described air curtain former forms can be an one side or more than the one side.
Compared with prior art, the beneficial effects of the utility model are:
1. in order to overcome the shortcoming of prior art, the utility model is to adopt air curtain to isolate (screen closes) mode or air curtain to be aided with fixedly that wall (plate, frame) mode is controlled at kiln waste gas the method for collecting waste gas with modes such as adopting the collection gas hood in the certain space.According to the charging discharging working method of kiln and the loading and unloading space requirement of maintenance of equipment maintenance, around the kiln or several orientation (aspect other fixedly on wall (plate, frame) a certain height of isolating with certain speed and the thick formation air curtain wall that flows, waste gas is controlled in the space of kiln mouth top, again with gas skirt and pipeline with gas sampling, through the airduct carrying-off, handle.
2. the utility model can solve the kiln waste gas that can not seal because of kiln working method and equipment loading and unloading space requirement and reclaim problem, people and material can freely pass through in air curtain, can satisfy the requirement in equipment loading and unloading space, and operation maintenance is convenient, the possibility of corrosion is little, because the shielding action of air curtain, exhausted air quantity are more narrow-minded than what collect with the simple set gas hood, collection rate can be up to more than 95%, simple in structure, power cost is low, and flexible and convenient operation can satisfy environmental protection requirement.
