Technical field
The present invention relates to a kind of smoke dust sampling gun, particularly a kind of flue dust heating sampling gun that can simultaneously heat filter cylinder and sampling pipe.
Background technology
Smoke dust sampling is power plant boiler discharge, equipment performance is tested and the important step of environmental protection supervision, generally carries out smoke dust sampling by smoke dust sampling gun.In practical application, the humidity ratio of some smoke dust in flue is larger, when using the smoke dust sampling gun of traditional non-power pattern of fever to sample, because the internal-external temperature difference of sampling gun is comparatively large, condensate water can be produced in the exhaust tube of sampling gun, along with the time of sampling increases, various gas and the dust of flue has been mixed in condensate water, to accumulate over a long period just crystallization in exhaust tube, cause exhaust tube to block, thus affect the use of sampling gun; And, smoke moisture is crossed conference and is drenched filter cylinder, sampling filter cylinder is met wet water absorbent and sampling resistance can be caused to increase blocking or sampling filter cylinder is broken, sampling is caused to carry out or failure, sampling filter cylinder and smoke dust sampling head stick together, to making sampling filter cylinder original weight change, causing sampled result abnormal, smoke dust sampling quality cannot be ensured.
On prior art smoke dust sampling gun many employings filter cylinder, the filter cylinder of structure to smoke dust sampling gun of direct winding screw electric heating tube heats, because heating tube directly contacts with flue dust, steam in flue dust and dust granules can cause breaking-up to heating tube, for protection heating tube, manufacturer applies anti-stick coating on heating tube, to avoiding flue dust to the erosion of heating tube and making to insulate between heating tube and filter cylinder, but, the anti-stick coating that heating tube applies can produce certain influence to the heating and thermal insulation effect of heating tube, and coating damageability, between heating tube and filter cylinder, insulativity can not be guaranteed.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and provide a kind of insulating property good, can to filter cylinder and sampling pipe heating and thermal insulation realize the flue dust heating sampling gun of temperature control, Automatic-heating simultaneously.
Realizing the technical scheme that the object of the invention adopts is, a kind of flue dust heating sampling gun, at least comprise smoke dust sampling cylinder, well heater, smoke dust sampling cylinder front end is provided with the smoke dust sampling mouth be communicated with smoke dust sampling cylinder, rear end is provided with the soot sampling tube be communicated with smoke dust sampling cylinder, smoke dust sampling cylinder inside is provided with filter cylinder, described well heater is the spring heating collar of built-in thermoelectric idol, smoke dust sampling cylinder and soot sampling tube are all closely arranged with spring heating collar outward, described spring heating collar is two-tube turn, one end of two turns connects to form spring heating collar, the other end respectively connecting power line forms the both positive and negative polarity of spring heating collar, outer tube is provided with outside spring heating collar, outer tube one end and smoke dust sampling gonys end are fixed, the other end is provided with temperature controller and attaching plug, temperature controller is serially connected between spring heating collar and attaching plug, a control port linking springs heating collar wherein power lead of temperature controller, the temperature signal input mouth of temperature controller connects the signal wire of thermopair.
Described outer tube is cylindrical shape, and outer tube end is provided with sleeve, and outer tube to be stuck in sleeve and to be connected with sleeve.
Temperature controller and attaching plug are installed in sleeve.
Described ferrule barrel is provided with the through hole matched with soot sampling tube caliber.
Described outer tube is provided with draw-in groove, and draw-in groove and outer tube are connected.
Described outer tube is provided with pitot tube, and pitot tube snaps in draw-in groove.
Described outer tube is threaded with the bottom of smoke dust sampling mouth.
Described smoke dust sampling mouth comprises the sampling mouth and bend pipe that are threaded.
As shown from the above technical solution, in flue dust heating sampling gun provided by the present invention, smoke dust sampling mouth, smoke dust sampling cylinder and soot sampling tube are interconnected and form smoke dust sampling passage, filter cylinder is arranged in smoke dust sampling cylinder, spring heating collar is set in outside smoke dust sampling cylinder and soot sampling tube, spring heating collar and flue dust completely cut off by smoke dust sampling cylinder and soot sampling tube, avoid the erosion of flue dust to spring heating collar, and make to produce between spring heating collar and filter cylinder and reliably insulate, spring heating collar heating smoke dust sampling cylinder and soot sampling tube, flue dust in smoke dust sampling cylinder and soot sampling tube is heated evenly, ensure that sampling is smooth and sampled result is accurate, spring heating collar and external environment are isolated by outer tube, protection spring heating collar, extend spring heating collar serviceable life.
Spring heating collar is the spring heating collar of built-in thermoelectric idol, thermopair can in sampling process the temperature of real-time measuring spring heating collar, and detection signal is delivered in temperature controller, temperature controller is according to the break-make of the temperature signal control spring heating collar heater circuit of input, effectively can avoid occurring that spring heating collar temperature is too high and cause heat waste, temperature is low causes flue dust heating insufficient, bonding soot dust granule thing on filter cylinder, thus realizes Automatic-heating and the temperature control of smoke dust sampling gun; Spring heating collar is two-tube turn, and therefore two power leads of spring heating collar are positioned at homonymy, and power lead length is short, decreases the possibility of power lead fault generation and saves power lead material.
The sampling mouth of smoke dust sampling mouth is threaded with bend pipe, sampling mouth can be screwed off the sampling mouth more renewed when mouth of sampling is blocked by flue dust, avoids smoke dust sampling mouth integral replacing waste material.
Compared with prior art, flue dust heating sampling gun provided by the invention, between each part, the mode of suit that adopts connects more, easy accessibility; This sampling gun can carry out heating and thermal insulation to filter cylinder and sampling channel simultaneously, and realizes Automatic-heating and temperature control, and ensure that sampling is smooth and sampled result is accurate, sample effect is good.
