Abstract
The utility model provides a boiler flue wind pressure detection anti-blockage device. The boiler flue wind pressure detection anti-blockage device includes an anti-blockage sampler, a first valve, a second valve, a third valve, a pressure detection device, a gas back-blowing device and a control cabinet; a sampling port of the anti-blockage sampler is inserted into a flue; the outlet of the anti-blockage sampler is connected with the inlet of the first valve; the outlet of the first valve is divided into two paths; one path of the outlet of the first valve is connected with the pressure detection device through the second valve; the other path of the outlet of the first valve is connected with the outlet of the gas back-blowing device through the third valve; and the control cabinet is connected with a control end of the gas back-blowing device. With the boiler flue wind pressure detection anti-blocking device of the utility model adopted, the problem of blockage can be effectively solved, and at the same time, the wind of the boiler flue can be tested accurately.
Description
Technical field
The utility model relates to a kind of blast and detects anti-block apparatus, is specifically related to a kind of boiler flue blast and detects anti-block apparatus.
Background technology
During the blast of traditional detection boiler flue, generally by the sample tap instrument tube is connected with the detection boiler flue, then manage with detecting device and be connected by table, thereby realize the blast test of boiler flue, yet showing pipe in test process, this method of testing can produce latch up phenomenon, need to manually be dredged, and detecting device shows and often not to prepare or slow in reacting at the testing process Wind pressure, exert a certain influence to boiler operatiopn or monitoring, so the stoker personnel can't be in time according to flue blast adjust operation operating mode, security and the economy of boiler operatiopn have also been affected.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides the boiler flue blast to detect anti-block apparatus, can effectively solve the problem of obstruction, can test accurately the blast of boiler flue simultaneously.
In order to address the above problem, boiler flue blast described in the utility model detects anti-block apparatus and comprises anti-blocking sampler, the first valve, the second valve, the 3rd valve, pressure-detecting device, gas back-blowing apparatus and switch board, the sample tap of described anti-blocking sampler inserts in described flue, the outlet of described anti-blocking sampler is connected with the entrance of the first valve, the outlet of described the first valve is divided into two-way, second valve of leading up to is connected with pressure-detecting device, another road is connected with the outlet of gas back-blowing apparatus by the 3rd valve, described switch board is connected with the control end of gas back-blowing apparatus and the control end of the 3rd valve respectively.
The porch of described gas back-blowing apparatus is provided with air strainer.
Described gas back-blowing apparatus is the nitrogen back-blowing device.
Described the first valve is ball valve.
Described the second valve and the 3rd valve are Solenoid ball valve.
The utlity model has following beneficial effect:
Boiler flue blast described in the utility model detects anti-block apparatus and is provided with anti-blocking sampler, pressure-detecting device, gas back-blowing apparatus and switch board, can with boiler flue, be connected by described anti-blocking sampler, and detect accurately in real time the blast of boiler flue by pressure-detecting device, when stopping up appears in flue, control gas back-blowing apparatus by switch board and carry out blowback, thereby the blockage problem of the pipeline that effectively removes smoke, avoid manually dredging the problem of bringing, and then improve the accuracy that pressure-detecting device detects the blast of boiler flue.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is that anti-blocking sampler, 2 is that pressure-detecting device, 3 is that gas back-blowing apparatus, 4 is that switch board, 5 is that the second valve, 6 is that the 3rd valve, 7 is the first valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 1, boiler flue blast described in the utility model detects anti-block apparatus and comprises anti-blocking sampler 1, the first valve 7, the second valve 5, the 3rd valve 6, pressure-detecting device 2, gas back-blowing apparatus 3 and switch board 4, described the second valve 5 and the 3rd valve 6 are Solenoid ball valve, the sample tap of described anti-blocking sampler 1 inserts in described flue, the outlet of described anti-blocking sampler 1 is connected with the entrance of the first valve 7, described the first valve 7 is ball valve, the outlet of described the first valve 7 is divided into two-way, second valve 5 of leading up to is connected with pressure-detecting device 2, another road is connected with the outlet of gas back-blowing apparatus 3 by the 3rd valve 6, described switch board 4 is connected with the control end of gas back-blowing apparatus 3 and the control end of the 3rd valve 6 respectively.In addition, described gas back-blowing apparatus 3 is the nitrogen back-blowing device, and the porch of described gas back-blowing apparatus is provided with air strainer.
Specific works process of the present utility model is as follows:
Sample tap and the boiler flue of described anti-blocking sampler 1 are connected; flue gas enters into described the first valve 7 through anti-blocking sampler 1; and enter into described pressure-detecting device 2 by described the first valve 7 and the second valve 5 and make described pressure-detecting device 2 and be connected, thereby the blast that can measure in boiler flues by described pressure-detecting device 2; Described the second valve 5 and the 3rd valve 6 are Solenoid ball valve, when latch up phenomenon occurring, described switch board 4 is controlled the Air Reverse blowing apparatus and is carried out blowback, thereby effectively pipeline is cleared up, simultaneously when blowback is complete, the user can close the 3rd valve 6 by switch board 4, thereby thoroughly solves the impact of line clogging on the testing result of pressure-detecting device 2, the inconvenience of simultaneously avoiding artificial dredge blockage flue to bring.
